OAKLAND, Calif. -- The Golden State Warriors lost to the Utah Jazz 105-99 in a game that meant little to the hosts beyond building habits.

The Warriors had nothing tangible to gain but perhaps benefited from testing their mettle against Rudy Gobert at the rim (he was as brilliant as his 17 points, 18 boards and two blocked shots suggests). It was also the game that saw Kevin Durant and Stephen Curry get their first minutes together since Feb. 28, when Durant suffered an MCL sprain against the Washington Wizards.

"I mean it's been a while since we played together, but the flow was there," Curry said after the game. "It was kind of choppy at first. That's the way Utah kind of slowed the tempo down."

He added, "We had some bright spots, some good runs, got some good spurts."

On Curry and Durant playing a lot simultaneously, Kerr said, "That was part of the idea tonight was to get them as many minutes as possible, so we left KD out there longer than we did last game in terms of his runs. So both first and third quarter I think they got about 10 minutes action together, each."

Prior to that injury, the Durant/Curry dynamic had been workable, but not exactly living up to preseason expectations. Many thought they'd operate within a devastating pick-and-roll, and that has yet to happen. Still, the Warriors are successful with both on the floor, and Monday night gave us glimpses of how the two work together.

The beginning seemed to presage some deference, as Curry passed up an open 3-pointer to assist Durant on a midrange shot. Durant then returned the favor as he passed out of the post for a Curry 3 at the top of circle.

As the Warriors played lax defense, the fun stuff came later when Curry tossed an outlet to Durant that led to a Green dunk. The Warriors might have dominated this game had they finished more plays like that. Instead, they botched a few easy transition opportunities.

In the beginning, Curry didn't need easy baskets to do his damage, as he was content to shell the Jazz from deep (28 points, six 3-pointers in 30 minutes of play). As the season winds to a close, Curry looks, subjectively, like last year's MVP candidate -- finally. That's quite a positive sign for a Warriors team, obviously.

As for the Durant watch, he certainly looks to be in good condition on a couple of highlight plays. On one, Durant crossed over Dante Exum in transition and threw down a furious slam. On another, Durant zipped past Joe Ingles and dunked right in the face of Joel Bolomboy.

Of the dunks, Durant said, "It felt really good man, I can't lie. I'm a little hesitant early on these first few games, just exploding off and just making moves I normally make. Seems like most second halves these last two games I've just been saying, 'Forget it, just go out there and try some stuff.'"

Durant looks athletic as ever, and the midrange jumper is accurate, but the 3-point shot isn't quite there yet. Durant scored 16 points on 12 shots, but went 0-of-5 from deep. Despite more space than he had in Oklahoma City's offense, Durant is shooting 28.4 percent from 3-point territory over his past 19 games dating back to Jan. 20.

That's a luxury issue for a team that didn't have to try on Monday because their 1-seed status is assured. The Warriors have a few kinks to work out, but theirs are smaller and less gnarled than what everyone else is going through.

Warriors focus on chemistry as Stephen Curry joins Kevin Durant - ESPN (blog)

Several years ago, a groupof four chemists believedthey had stumbled upon evidence that contradicted a fairly well-established model in fluid dynamics.

Between 2013 and 2015, the researchers published a series of four papers detailing their results two in ACS Macro Letters and two in Macromolecules.Timothy P. Lodge, the journals editor and a distinguished professor at the University of Minnesota in Minneapolis, explained that the results were somewhat controversial, because they appeared to contradict the generally accepted model for how somepolymer fluids move.

Indeed, the papers sparked debate between the authors and other experts who questioned the new data, arguing it didnt upend the previous model.

Then, in 2015, the authors realized their critics might be correct.

The authors began to suspect something wasnt quite right after a 2015 paper in ACS Macro Letters reported significantlydifferent results. Last author Zhen-Gang Wang, a professor of chemical engineering at California Institute ofTechnology, explained:

We first got alarmed by the large discrepancy with our results reported in a paper by Cao and Lihktman (ref. 6 in our retractions) for a very similar system.

Wang and his team wanted to understand the source of this discrepancy, so they went back to check their data and protocols:

To resolve the discrepancy, we did a lot ofindependent checking using different protocols, including using a new program written from scratch by anotherstudent in one of the PIs group.

Theseindependenttestsconvinced us that our published results were wrong, Wang said.

Further digging revealedthe source of the problem: a glitch in the computer code used to derive their simulation results. Wang explained:

As we have described in our retractions, the source of errors was a coding glitch in thetreatment of the thermal bath.

Once Wang and his team understood what had happened, they contacted Lodge and other experts in the field to let them know:

We immediately informed the editor in chief for Macromolecules and ACS Macro Letters, Prof. Timothy Lodge, and sent out an e-mail message to dozens of people in the field, acknowledging that our previous results were wrong and told them about the errors.

Wang said this was an unfortunate but inadvertent mistake. And Lodge agreed:

There is no indication that the mistakes were deliberate in any way.

Even so, because the results were based on unreliable code, Lodge said that, a simple correction wasnt enough. Lodge reviewed the matter with the American Chemical Society (ACS), which publishes both journals, along withother experts in science publishing, and determined that a retraction was the right thing:

This case is unfortunate, but it happens. Science is self-correcting.

We commend Wang and his co-authors for their transparency and efforts to uncover and rectify the problem.

The retraction notices also provide an extensive account of what happened. Heres the retraction notice for the first paper in the series, Evolution of Chain Conformation and Entanglements during Startup Shear, published in ACS Macro Letters in 2013 and cited 12 times:

In recent years, we published a series of four papers in ACS Macro Letters and Macromolecules(1-4) reporting Brownian Dynamics simulation results on startup shear of entangled polymers for shear rates in the regime d > 1 but R < 1, where R and d are respectively the Rouse time and reptation time. Our results showed significant chain stretching (measured by the contour length of the primitive chain) and suggested, based on analysis of the different components of stress, that the origin of the shear stress overshoot was due to chain stretching followed by retraction instead of chain orientation, in contradiction to the predictions of the reptation/tube theory. Our results also implied violation of the empirical stress-optical rule generally believed to hold in this regime, as pointed out by Masubuchi and Watanabe.(5) Subsequently, Cao and Likhtman(6) published their simulation results on a very similar system and found results in strong disagreement with ours their results showed little chain stretching and conformed to the stress-optical rule.

In order to resolve these discrepancies, we performed many tests, including using a new code written from scratch. We are now convinced that our previous results were wrong. Both the new code and independent runs (on LAMMPS with the fix deform protocol) at Akron by Yexin Zheng, a joint student between Shi-Qing Wang and Mesfin Tsige using the equilibrated copies of systems from three different sources (one of our previous copies, a copy provided by Dr. Robert Hoy, and a new copy generated at Akron), produced results similar to those reported by Cao and Likhtman.

The source of errors has been identified to be in the treatment of the heat bath under shear, which resulted in much lower temperatures than T = 1 (in scaled units) for the sheared samples. The same errors were introduced in both the Langevin heat bath and the DPD heat bath. The reduced temperatures resulted in longer relaxation times. The chain stretching reported in our earlier work was thus a result of this artifact. These errors invalidate all the data at finite shear rates reported in our published papers, and render our conclusions baseless. The authors therefore request retraction of the Article Evolution of Chain Conformation and Entanglements during Startup Shear and the other three affected articles.

The other three retractions contain almost identical wording. Here are links to the notices and papers:

Chemistry papers challenged a paradigm - until the authors spotted ... - Retraction Watch (blog)

SALINA Harrah, Oklahoma native Apryl Saunders is compelled by the idea of one day defeating multiple sclerosis, or MS, a disease from which her mother suffers. But thats a long way from the love of softball that helped her get to Kansas Wesleyan University five years ago.

Saunders entered her freshman year at KWU as a talented softball infielder with dreams of becoming a doctor. As she pursued a pre-med track, her biology and chemistry classes began to capture her attention. Seeing her talent for the sciences, Dr. James Townsend, chair of the KWU chemistry department, helped her to apply for and get two remarkable research experiences.

First, she participated in a study abroad opportunity at the Nottingham Trent University in England.

Her research in chemistry there further stoked her interest and led her to apply for and receive a Research Experience for Undergraduates grant, funded by the National Science Foundation, to conduct research in structural biology at the University of Oklahoma.

Dr. Townsend helped me so much at Kansas Wesleyan, Saunders. The study abroad and REU opportunities were so important. Between sophomore and junior year, I still wanted to go to medical school after college, but I felt so confirmed by the research opportunity at OU that I came back to college determined to get a degree in chemistry.

After graduating with honors from KWU with a bachelors degree in chemistry and biomedical chemistry, Saunders entered the graduate program in chemistry at OU to pursue a doctoral degree in medicinal chemistry.

Currently working in the Duerfeldt Lab, Saunders is researching medicines targeting diabetes and vision loss. For Saunders, the work is increasingly personal as she learns to manipulate molecules and medicines that can change and save lives. Her mother suffers with multiple sclerosis, and Saunders would one day like to dedicate her research efforts to treatments for MS.

I discovered I liked being behind the formation of medicines, Saunders explains, and less inclined to want to give or prescribe drugs. And as I learn about the chemistry of medicine and the differences we can make in treatment, I want to continue my work and see if I can possibly help change the outcomes of MS treatment. My mother suffers with MS and making a difference with MS is very important to me.

At KWU, a full 60 percent of the science faculty are women, which was a quiet but powerful inspiration for Saunders. The majority of science professors are women at KWU, Saunders says. Seeing so many women leaders created a great environment, and I felt like I had a place there. I was pushed to excel and felt as though I could be an accomplished scientist at KWU.

Kansas Wesleyan University is a private four-year college founded in Salina, Kansas in 1886.

Affiliated with The United Methodist Church, KWU offers unique and innovative undergraduate degrees and a Master of Business Administration. The university, recognized as a College of Distinction, is characterized by excellence within a caring environment and student-centered education. At Kansas Wesleyan, students are encouraged to get involved in the classroom and in the community, explore academic interests and participate in activities, learn and serve in Salina and the world.

MAYPEARL Not including edging Grandview by one run, Maypearl has outscored its opponents 66-9 in six seemingly scientific district victories.

Sixteen of those runs came during Friday night's 16-0 shutout of Keene High School at Panther Field and helped Maypearl High School remain the undefeated No. 1 seed of District 17-3A.

It was also the (10-6, 7-0) Panthers' seventh consecutive victory and the third team held scoreless during that stretch.

"The pitching has been a focal point this season and helped us get to where we are right now," Panther Head Coach Brian Bilbrey said. "Dakota (Davis) was great and has been all year long on the mound as has Lonnie (Brooks) and anyone else who has taken on that responsibility."

Despite the juggernaut success of the regular season, Bilbrey said he's reserving judgment on where this year's team stands with others he's coached.

"Each year each team has its own personality," he continued. "This year's team has done a really good job of putting in the work. They are always doing extra work on their own and its paid off with their play. We just keep working the way we have been working and try to build off what we've been able to accomplish. If we practice the right way with lots of energy and emphasize the details we feel good things will happen."

There was more than a possibility the Panthers felt on the proverbial "right track" after Davis tossed a two-hit, seven-strikeout and 60-pitch five-inning gem against the visiting Bulldogs. Only Payton Denning and DeMarcos Peireira were able to reel hits off Maypearl's right-handed ace during 14 total at-bats.

While the Keene struggled to earn bases, Maypearl stockpiled hits. It used 16 to score 16 runs and run-rule their district opponents two innings shy of a complete game. Six of those earned bases came from the bats of Brooks (3-for-4, 3 RBIs), Davis (2-for-3, 1 RBI), Luis Dermas (3-for-3, 5 RBIs) and Tanir Horton (3-for-4, 3 RBIs).

Every player on the Maypearl roster, save two players, got at least one hit. Every player, though, contributed, regardless of if it was a hit, run scored or a lead-extending sacrifice.

There were stolen bases in the first, third and fourth innings that helped buoy the Panther lead and basereunning that turned a seven-inning high school baseball district matchup into a blowout.

In addition to logging multi-hit and multi-steal performances on their season resumes, Brooks, Davis, Dermas and Horton accounted for 12 runs batted in.

Cole Maxwell, Chase Reeher and Sam Taylor helped round out the RBI total at 15. For Horton and the Panthers, though, there is one word that defines his current team versus ones in the past.

Chemistry.

"Our chemistry is stronger now than ever," he said. "We've had awesome chemistry in the past but this team seems locked in every at-bat, inning, game and stretch. Even when we stumble there's always someone to play savior whether its Luis, Robert (Pinter), Sam, Cole, Ken (McGinn) or Cory (Nix). We all have the same goal in mind and are unified by our desire to reach it. That's getting to the state championship one step at a time and winning the whole thing. You can't win a title in a team sport like baseball without chemistry."

That chemistry exists despite a possible txhightschoolbaseball.com snub that left Maypearl unranked a week after knocking off Grandview's Zebra, the No. 4 3A team in its state poll.

"Rankings don't mean anything to us because, at the end of the day, every team has to compete," he continued. "We play our best nine against another team's best nine and we go and compete. We play with a chip on our shoulders every game because we feel like we have something to prove to everyone every game we step inside the diamond. We love being the underdogs because it gives us a little extra motivation. It makes us who we are, chemistry included. Everybody from your starting pitcher to your bullpen pitchers and your leadoff batter to your pinch hitter or reserve players has to be on the same page. Baseball is like music. We're the instruments and Coach Bilbrey is the virtuoso. All we have to do is play."

The Panthers are seemingly stockpiling good vibes. They sit in first place and are in the driver's seat to the district championship with four games left on the regular-season schedule including a finale rematch with Grandview High School.

Counting Rice High School, Maypearl's 7 p.m. Tuesday opponent at RHS Bulldog Field, three of the Panthers' next four opponents have won less than five games. The (4-11, 3-4) Bulldogs lost their Friday night matchup to Scurry-Rosser High School 1-0. It was Rice's third consecutive loss.

"Rice is a good team that's well-coached," Bilbrey said about keeping the momentum this late in the season. "We'll have our hands full. It starts with our pitching. If we pitch well, play good defense, and get a couple of timely hits we'll give ourselves a chance."

Chemistry set: Maypearl's wild science has the Panthers on the top of 17-3A class after Friday district rout - Waxahachie Daily Light

Gena Marsh and her student Jovan have been spending their Time4Chem doing extra chemistry during lunch breaks, even synthesising solvents for school lessons.

I work in an international school in Italy, teaching IB Diploma Chemistry. Because of the city I live in there are always new students with different backgrounds and experiences in chemistry.

One of these students is Jovan he joined our school a year and a half ago from Belgrade in Serbia. His theoretical chemistry knowledge is superb, but his knowledge of practical techniques had been severely limited. Having few friends and little initial inclination to socialise (my Italian students are loud!) he spent a lot of time in my classroom and it became clear that we have a shared love of chemistry in all of its aspects from the mundane to the arcane!

So during lunchtimes and after school we have spent time developing his practical skills in chemistry and also introducing him to some of the other students in his year group with similar interests. Over the last 18 months his abilities have improved greatly.

Recently, in lessons, we have started organic chemistry and, while I have access to some solvents, over the years before I arrived the stocks were allowed to run out or were disposed of, either due to health and safety rules or lack of use.

This state of affairs has been in parts frustrating and heart-breaking, as some of the best reactions are denied to us. However, on one such occasion Jovan stepped up and offered to synthesise the missing solvent for a simple organic practical. As most of you will be aware, the synthesis of cyclohexanone is a two-step process: it took Jovan about 175 minutes to produce about 7 cm3 of it, but it allowed us to compare it with cyclohexane and cyclohexene, enabling my students to observe the differences in reactivity.

It was a great chance to see that the time he has spent in the lab has been put to good use and along the way he has made friends too. For example, many of my other students seek him out at lunchtimes when they need more help.

For Jovan, he enjoys being in the chemistry lab and I think he appreciated having someone trust him to do this reaction with minimal supervision. When I asked, his response was "but I enjoyed the synthesis"!

Michigan State Universitys Chemistry Club took first place in the 13th annual Battle of the Chemistry Clubs, or BCC, competition held Feb. 1.

The MSU Younger Chemists Committee sponsors the annual BCC competition to attract chemistry clubs from throughout Michigan. Held on the MSU campus, this years competition included 10 colleges and universities in teams of at least four students each. The BCC first began as a competition between UM-Flint and the University of Detroit, Mercy, in 2007.

"On behalf of the department, I congratulate our Chemistry Club champions, said Robert Maleczka, professor and chair of the Department of Chemistry in the MSU College of Natural Science, or NatSci.This group of chemistry majors has shown a great esprit de corps and are terrific examples of students getting the most out of their MSU experience.A shout-out to the clubs advisor, Sheba Onchiri, is also most certainly in order!"

I consider such competitions as one of the best ways to demonstrate students talents, Onchiri said. If we fail to provide these kinds of forums, some students may not discover their hidden talents and other skills they possess. Above all, these events help students build self-confidence, teamwork and other soft skills vital in the world today. I am so proud of the Chemistry Club and all they have accomplished in the short time they have been in operation. Go Legends!

BCC events cover a full day. Competitive events in the morning include chemistry Jenga, a safety rules obstacle course, identifying elemental trivia in haiku poems and tests on International Union of Pure and Applied Chemistry, or IUPAC, knowledge. IUPAC is the unified system of nomenclature, measurements and atomic mass values for chemists. MSU dominated in all these categories and held first place after the mornings events.

"Our expectation as we were waiting for the results of the morning was just to be in the top five, said Natasha Perry, MSU Chemistry Club vice president.

MSU's club continued to hold its lead throughout the afternoon in the titration race and in timed events that tested students knowledge of density laws and regions of the visible light spectrum. The competition closed with jeopardy-style trivia questions on a variety of chemistry knowledge before moving on to the Final Jeopardy round and winning the competition.

When we found out that we won, we were at first speechless, Perry said. I know that winning will allow our club to flourish and was an exceptional way for seniors to finish their last year."

A senior, Perry plans to pursue a Ph.D. in organic chemistry, with a focus on either organometallics or total synthesis. She is still deciding which graduate program to attend.

I believe this success at the BCC will be very important for the future of MSU's Chemistry Club in attracting members, said Austin King, MSU Chemistry Club president, who started the club in spring 2019. Having fun and being passionate about chemistry is the clubs main focus; students will see the accomplishments the club has made and want to be a part of it.

King will start graduate school in chemistry at MSU in the fall and looks forward to seeing new members help the club continue to grow.

MSU's Chemistry Club fosters and promotes passion for chemistry among students, who come from a variety of backgrounds and majors but share a common desire to expand their knowledge of the world around them. The club focuses on having fun and exploring chemistry topics rarely addressed in standard colloquia. Club members enjoy exploring some of the unusual as well as the practical applications of chemistry.

ATLANTIC CITY The school district advertised three times for a certified chemistry teacher last summer and fall, and three times they failed to get a candidate to accept the job.

So they turned to Edmentum, a provider of online courses, to fill the gap. This year, four classes at the high school are being taught via the online course, with backup support from a teacher.

This is the way of the future, said Assistant Superintendent Sherry Yahn, who said they are looking at other online programs.

Not everyone is happy with the shift. Students in the chemistry classes didnt mind being able to work at their own pace, but almost all interviewed said they would prefer a live teacher.

The online chemistry classes at Atlantic City High School represent the intersection of several critical education issues: a shortage of science teachers, school funding cuts and growth in online courses.

Just 80 new teachers were certified in chemistry in 2016, according to state Department of Education data. Just 41 new teachers were certified in physics.

While the online co
urses may seem to provide a solution to budget and teacher-shortage issues, educators are leery of turning their schools into online academies.

ATLANTIC CITY A tiny coffee shop next to the Atlantic City Rescue Mission offers a welcomi

Atlantic City is at ground zero in the shift. Yahn said they are still looking for a chemistry teacher. But they are also considering using Edmentum courses for an Alternative High School program next year.

The Atlantic City school board approved spending $35,400 for as many as five Edmentum EdOptions Academy chemistry classes at its January meeting. But board members peppered Yahn with questions about why it was necessary. Yahn said applicants took the job, then backed out.

The district had a substitute in the class, Diana Arndt, who is certified in Earth science but not chemistry, so she could not teach the entire year. She remains in the class to assist.

The statewide shortage makes the position competitive. At least three area school districts are looking for chemistry teachers next year.

MIDDLE TOWNSHIP Tammy DeFranco hears it all the time.

Ralph Aiello, principal at Cumberland Regional High School, said hes looking for a combined chemistry/physics teacher for next year. So far, he has had just two applications.

Linda Smith, president of the New Jersey Science Teachers Association, said she is working with colleges to develop programs that recruit former or retired scientists into teaching as a second career.

People can just make more money as scientists than they can as science teachers, she said. Some do want to teach. But they need training and mentoring. People who are good at science are not always good at explaining it.

Claudine Keenan, dean of education at Stockton University, said school districts contact her constantly looking for math and science teachers. Stockton has made an effort to encourage science majors to also get their teaching certificates and has had some success.

Youre supposed to do fun labs in chemistry, she said. We only did one.

What does every start-up business want from the ideal investor? The answer may seem painfully obvious: surely it's just cash and lots of it.

But new research has discovered that founders of new businesses often crave something far more valuable from their backers personal chemistry.

A report from UK Innovation Hub, a new start-up programme backed by German outfit Innogy and Tech City UK, the government-backed organisation that aims to help create tomorrows technology entrepreneurs, has revealed that start-ups want personal chemistry and trust above all other considerations when weighing up potential investors.

The findings give weight to the adage that people only do business with those they know, like, and trust.

When it comes to external investors, the research found that start-up bosses are obsessed with three key areas. These are: personal chemistry, a strong track record and access to a great network. There was a consensus from founders that the ideal investor will be someone they like and who is in tune with their product and vision.

Start-ups want personal chemistry and trust above all other considerations when weighing up potential investors

Starting a business is never straightforward and there tend to be highs and lows in the early days. Founders want investors at their side who will roll with the punches and offer words of wisdom, not reproach, if there is a bump in the road.

Indeed, the research found that founders are keen to find investors who will act as a mentor or coach when the need arises but who will otherwise be low maintenance.

As well as highlighting the priorities for start-up founders, this poll looked at the least important factors. Accelerators and incubators promising free office space and HR support are missing a trick, it emerges, as these are ranked amongst the least useful services.

With a huge array of different start-up programmes and investment options available, we wanted to get to the heart of what really matters to founders when considering funding, said Innogys Thomas Birr.

Finding someone they liked or trusted with an understanding of their product and vision, was incredibly important. Access to further funding and a great track record were also key considerations, while the add-ons many programmes provide such as free office space and pitch training were a low priority.

The research, which gathered views from 164 British start-ups, also looked into the changing funding landscape. A decade ago, bank loans were one of the most popular ways to fund a new business. Today, just over one in 10 entrepreneurs would choose this route, compared to 66pc who would consider angel investment, and 55pc who would look to venture capital.

Matt Lerner, venture partner at 500 Startups, which helped to compile the research, said: These founders are dead-on. Taking money from a venture-capitalist is like a 10-year marriage. It really has to come down to trust and chemistry. Thats why its great to reference-check your VCs before you take their money. My old roommate used to say, I only trust God and my mum. And with my mum, I cut the cards.

FLINT (WJRT) (12/05/19) - It's a question stylists face repeatedly over the years: can coloring or straightening your hair cause cancer?

A recent study says permanent hair dye and chemical straighteners may increase risk for breast cancer.

Even before hearing about this study, one woman says she has always insisted on all natural color products and refused to use any chemical products in her hair.

"My mother passed away from breast cancer, and that's why I don't use any type of chemical relaxer in my hair right now. There are lots of things that I'm reluctant to do because of the fact that it has not been unproven that their is a link between the chemicals and cancer, and it's just not worth it," Grand Blanc resident, Shannon Polk said.

The study was published in the International Journal of Cancer. Researchers used data from nearly 47,000 women over several years.

In general, women using permanent dye had a 9% higher risk of developing breast cancer.

The study also showed that Black women using permanent dye had a 45% higher risk of breast cancer, compared to those who skipped out on those products.

The more often people used the products, the risk of developing cancer also grew.

One stylist says she's been hearing about studies like this one for years, and the findings are usually inconsistent.

She says she does not think this will impact people who already are and have been treating their hair.

"They wouldn't stop because it's a vanity thing. You don't want to go grey too early because you have some people that started graying really early in life, in their 20's maybe, and they just don't want to deal with it. They feel like it makes them look old, and so they're going to color it. Either they'll do a rinse, they'll do a semi-permanent, they'll do a permanent. They're going to do something," Nora Griffin said. Griffin is a hair stylist at Park Place Hair Studio in Flint.

Scientists do say that although there is prior evidence to back up the study's findings, there still needs to be more research.

The University of WisconsinMadison Department of Chemistry received the 2020 Diversity Award from the University of Wisconsin System Board of Regents.

According to a news release by UWMadison Communications, the UWMadison Chemistry Department received this award in recognition of their programs designed to help underrepresented groups in the field excel in the Chemistry graduate program.

The news release said one of the main underrepresented groups in the doctoral programs are women, many receiving undergraduate degrees but not moving on from those programs.

Chair of the Chemistry Department Judith Burstyn said in the release that the award celebrates their efforts towards creating more diversity, and this is just the beginning of the departments efforts.

New PEOPLE program director emphasizes access, diversity as paramountThe Precollege Enrichment Opportunity Program for Learning Excellence program recently appointed its former assistant director as its new director in Read

These achievements are the result of everyone in the department who works tirelessly to build diversity through the creation of key programs and mentorship of students, Burstyn said in the news release.

A few of the UWMadison Chemistry Departments key programs include Chemistry Opportunities and Research Experiences for Undergraduates. According to the programs websites, they serve as opportunities in the department to reach underrepresented populations and allow them to explore the doctoral programs.

One of the key programs designed for graduate student success is a program called Catalyst. According to the programs website, Catalyst is a mentoring program geared towards helping first generation, low-income and underrepresented student populations.

The program consists of a peer-mentoring scaffold and a professional development seminar series that helps create a sense of belonging and connection between participating first-year students and their peers, department, campus, and the Madison community, the Catalyst website said.

UW recognizes efforts, challenges faced by returning adult studentsThe University of Wisconsin recently announced the winners of its Outstanding Undergraduate Returning Adult Student Awards. These awards were created Read

According to the news release, the UW System Office of Academic and Student Affairs chooses the recipients of the award. Other recipients across the state include an Associate Professor from the UWMilwaukee School of Architecture and Urban Planning and UWStouts Fostering Success program.

The news release said the Board of Regents awards each recipient $7,500, and the chemistry department will put this money towards further development of its existing programs to reach underrepresented students.

The three recipients of the award will be honored at the 12th annual Regents Diversity Awards at the Board of Regents meeting in Madison Feb. 7.

Everyone benefits from diverse perspectives, Burstyn said in the news release. We recognized that need in our department and have worked to find effective solutions.

Soap fans love a good bad boy! Thomas Forrester fits the bill of show antagonist nicely on The Bold and the Beautiful because hes tall, dark, handsome, and goes for what he wants!

Thomas (Matthew Atkinson) currently has two women interested in him. Whether she can admit it or not, Hope (Annika Noelle) is drawn to the guy. Also, Zoe (Kiara Barnes) has moved on from Xander (Adain Bradley) and is now interested in Thomas.

Which lady has the best chemistry with Thomas? Soap Hub posed this question to BB fans. Read on for the results!

The majority of you, just under 68%, feel that Zoe has the best chemistry with Thomas. Zoe knows better than anyone what Thomas is capable of yet she cant fight the attraction she feels for the confidant designer.

Thomas is very convincing when he persuades Zoe to think that he has genuine feelings for her. He may not truly love her, but theres no denying there are sparks between them.

The rest of you, just over 32%, feel that Thomas and Hope have the best chemistry. Hope has literally run away from this man, but theres something that keeps bringing her back to him.

It cant be just her love for little Douglas (Henry Joseph Samiri) that draws her to Thomas. Maybe its the danger? Maybe its the charm? There are days when Hope cant even concentrate on her work while sitting in the same office as Thomas.

Thomas probably shouldnt pursue either of these women until he gets his act together. If he were to stop trying to manipulate everyone around him, maybe a woman in his life could get past that dangerous element he has and decide hes someone with whom she could truly build a future?

The Bold and the Beautiful Poll Results: Who Has the Most Chemistry with Thomas? - Soap Hub

Molecular nitrogen has been found to actually speed up some reactions that use ruthenium-based catalysts despite being considered inert for the purposes of most chemical reactions.1 This behaviour could also affect other catalytic processes, so dinitrogen should no longer be considered as a simple inert carrier gas, the team from the UK and China say.

Heterogeneous catalytic reactions usually consist of two or three phases, including a solid-phase catalyst, as well as gas- and/or liquid-phase reactants and solvents. Most studies focus on improving the catalysts, but as these processes occur at interfacial sites, species from the other two phases can also affect the catalytic properties. Dinitrogen is commonly used as carrier or protective gas in catalytic reactions because it is considered to be unreactive. But now chemists have discovered that the molecule can sometimes behave in unexpected ways.

Dermot OHare of the University of Oxford and colleagues investigated the hydrodeoxygenation of p-cresol to toluene over a titanium oxide supported ruthenium catalyst and found that introducing 6 bar dinitrogen caused a 4.3-fold activity increase at 160C under batch conditions. The greatest impact of this work is to demonstrate that a hitherto perceived unreactive molecule can now be observed to increase catalytic performance, OHare says. This is extremely surprising and unusual.

The researchers carried out experiments at different temperatures and using various ruthenium catalysts. Their results showed an enhancement on all the studied materials. DFT calculations helped them understand the mechanism involved. We think the nitrogen molecule may convert to a more reactive NNH species on the metal surface, OHare says. Jun Li at Tsinghua University, who also participated in the study, explains that this NNH pathway for dinitrogen activation, which he says mimics the biological pathway used by nitrogen-fixing bacteria, has been theoretically proposed for ammonia synthesis2 but had not been confirmed experimentally until now. This work provides the first experimental evidence of the unusual formation of NNH or NNHx species, he says.

Normally, nitrogen is considered extremely inert, which makes this proposal quite exciting, as such behaviour is unprecedented, says Michael Fryzuk of the University of British Columbia, Canada, who was not involved in the study. The role as a catalytic promoter facilitating protonation of surface-adsorbed hydroxyl species is quite enticing, but as the authors are careful to note, the role of nitrogen may also be to open up more sites on the ruthenium surface by removal of surface hydrogen atoms.

OHare thinks the new results could have a wider impact. This may be a more general concept and applicable for other metal-based catalyses, he says. Researchers should now add nitrogen to their gas streams to see what happens. Fryzuk agrees that this would be an interesting thing to do. There may be some surprises that await, he adds. Ji believes that the NNH pathway could become a useful strategy for ammonia production. On the theoretical side, we plan to explore a wide range of metals to determine which metal surface can facilitate this pathway the best. Then it might be used for nitrogen-to-ammonia conversion, he says.

Chemists taken aback as dinitrogen found to speed up some reactions - Chemistry World

In the fast-paced, complicated world of quantum chemistry, A.I.s are used to help chemists calculate important chemical properties and make predictions about experimental outcomes. But, in order to do this accurately, these A.I. need to have a pretty strong understanding of the fundamental rules of quantum mechanics, and researchers of a new interdisciplinary study on the topic say these quantum predictions have been lacking for some time. A new machine learning framework could be the answer.

While previous renditions of quantum-savvy A.I. algorithms have been useful, say the new studys researchers, they have also failed to capture some of quantum chemistrys most important characteristics in their prediction models. Namely, these previous models have neglected to account for electronic degrees of freedom in these trials which are the number of changing factors required to describe a specific state of a system.

Quantum mechanics, famously, allows for states to simultaneously exist and not exist, and using degrees of freedom can help scientists better understand how to accurately and usefully describe a system. Without accounting for these degrees of freedom, previous A.I.s have described these quantum chemistry experiments in more classical scalar, vector and tensor fields, which required much more calculation time and energy.

Researchers of this new study have instead designed a framework that will describe them in the more quantumly accurate, and faster, form of ground-state wavefunctions. The study describing their approach was published last week in the journal Nature Communications.

One of the studys authors, Reinhard Maurer from the Department of Chemistry at the University of Warwick, said in a statement that their algorithms combined flexibility and quantum know-how will help make it an important tool for quantum chemistry.

This has been a joint three year effort, which required computer science know-how to develop an artificial intelligence algorithm flexible enough to capture the shape and behaviour of wave functions, but also chemistry and physics know-how to process and represent quantum chemical data in a form that is manageable for the algorithm, said Maurer.

The study authors write that this deep-learning framework, called SchNOrb (which we can only imagine is as fun to pronounce as it looks), allows them to predict molecular orbits with close to chemical accuracy which in turn provides an accurate prediction of the molecules electronic structure and a rich chemical interpretation of its reaction dynamics.

The capabilities demonstrated by this algorithm would help chemists more effectively design purpose-built molecules for medical and industry use.

However, while the authors write that SchNOrb is proof that such an application is useful and feasible, the large number of atomic orbitals its able process also leaves it vulnerable to increased prediction errors as well. The authors write that the accumulation of these prediction errors eventually led to a bottleneck in the prediction process in many ways the same kind of efficiency error they were trying to improve from previous approaches.

In order to account for this problem, the authors write that in future studies theyll need to learn more about and improve the neural network used in this study.

That said, the authors are still confident that this preliminary research demonstrates a path forward toward more effective collaboration between quantum chemists and these quantum-savvy A.I.s, and that this collaboration will become an essential part of the discovery process in years to come.

>Abstract:

Machine learning advances chemistry and materials science by enabling large-scale exploration of chemical space based on quantum chemical calculations. While these models supply fast and accurate predictions of atomistic chemical properties, they do not explicitly capture the electronic degrees of freedom of a molecule, which limits their applicability for reactive chemistry and chemical analysis. Here we present a deep learning framework for the prediction of the quantum mechanical wavefunction in a local basis of atomic orbitals from which all other ground-state properties can be derived. This approach retains full access to the electronic structure via the wavefunction at force-field-like efficiency and captures quantum mechanics in an analytically differentiable representation. On several examples, we demonstrate that this opens promising avenues to perform inverse design of molecular structures for targeting electronic property optimisation and a clear path towards increased synergy of machine learning and quantum chemistry.

Karen Aston began planning the Longhorns trip abroad two years ago.

Texas head coach wanted to take her players on an expedition that would expose them to different cultures and basketball competition. She had done the research, contacting other schools to gauge where she should take her team and what they should do. She also hired a travel company that specializes in basketball tours.

Eventually, Aston settled on Italy.

I picked Italy because I believe theres a lot of historical value, and you want it to be a good cultural experience for the team, Aston said. I think its a bit of a recruiting tool if youre able to tell a recruit that theyre going to go to one of these places in their career here. Everyone kept saying that Italy was the one to go on. I can understand why, it was a remarkable trip.

The team took flight on Aug. 11 and stayed for 10 days, making stops in Rome, Venice and Lake Como. However, Florence was deemed the consensus favorite stop among coaches and players alike.

Senior guard Ariel Atkins had been in Japan prior to Texas trip, playing for Team USA in the U24 Four Nations Tournament. She joined the Longhorns in Florence on Aug. 16.

We wanted to go see Ariel (at the hotel), she had just gotten back from Tokyo, sophomore wing Jada Underwood said. The elevator is literally smaller than my dorm shower. They wouldnt let more than four people get on there. And so we all get in, and its 12 or 13 of us.

The elevator reached the third floor before stalling out.

And we just dropped down, Underwood said. The light went off for a second, and then it came back on and we were just like Were stuck yall. There was hot breath, sweat, it was horrible.

The team spent 45 minutes waiting to be released.

I didnt get to see them until the next morning, Atkins said. That was probably the most fun part. I feel like they missed me as much as I missed them. I think this trip definitely gave us a chance to kind of see each other in different ways.

The elevator is going down in history, Hosey said. I feel like we got a lot closer. Now, we can go to each other and say Hey, youre slacking, pick it up. I feel like, before the trip, we couldnt do that because we didnt know each other that well. We thought we knew each other, but the trip made us closer.

The improvement in the players bond translated on the court. The Longhorns opened with a 52-50 loss against Hannover in overtime. But in its second game, the team was able to seal the deal with a 88-56 victory over FSG Academy. In the Italy exhibition finale, the women decimated Basket Costa, crushing them 122-36.

Now back home, the players hope to see their progress continue.

We learned togetherness, Underwood said. We had to be stuck in an elevator, you know we had to be together. You can tell when a team has chemistry on the court. I think the chemistry we developed over there carries onto the court, and its carried on since weve been back.

Leading marine scientists have detailed a litany of serious deficiencies by Australias chemical regulator that have failed to prevent the ongoing pollution of the Great Barrier Reef catchment, where they found excessive levels of several pesticides banned by other countries.

A new paper, co-authored by reef water quality expert Jon Brodie and fisheries veterinarian Matt Landos, found that pesticide regulation and management in the reef catchment areas of Queensland had failed to prevent the exposure of ecosystems to the significant risk of agricultural chemicals.

The report detailed extensive concerns about the processes and practices of Australian Pesticides and Veterinary Medicine Authority (the APVMA), which is responsible for the regulation and licensing of chemicals.

More than 80 of the active ingredients registered for use in Australia are prohibited by the 27 member countries of the European Union, the study says. This includes 17 pesticides that are known to be or likely or probable to be carcinogens and 48 pesticides flagged as potential endocrine [hormone] disruptors.

More than 20 are classified as either extremely or highly hazardous by the World Health Organisation. Three of the pesticides are subject to actions by international conventions but are still used in Australia.

Among the pesticides the scientists show were detected in the reef catchment is Atrazine, a herbicide banned in 60 countries due to concerns about water contamination but registered for use in Australia.

The study documented how more than 50 individual pesticide residues had been detected in Great Barrier Reef waterways, and how the highest concentrations were in freshwater areas adjacent to areas of intensive cropping.

Where monitoring exists in waterways (and little systematic monitoring of residues in waterways occurs in Australia), pesticide residues are detected widely and at concentrations often above Australian guidelines (where guidelines exist), and commonly above published effect levels, especially in intensive cropping situations, the study said.

In the freshwater and estuarine reaches of Barratta Creek south of Townsville, with a catchment dominated by irrigated sugarcane cultivation and smaller areas of cotton and horticulture, a total of 43 pesticide residues were detected with seven pesticides exceeding ecologically relevant water quality guidelines/trigger values during the study period and four (including Atrazine) of these exceeding guidelines for several months.

Even far offshore in Great Barrier Reef marine waters pesticides are always found due to their surprisingly long half-lives in marine waters and long residence times in the Great Barrier Reef lagoon.

The study detailed how the regulation and management by the APVMA had failed to prevent the exposure of ecosystems to chemicals, including the slow speed of regulatory reviews, which have in some cases dragged on for more than a decade. The authors concerns included that the regulator was focused on agricultural interests rather than environmental protection.

A major deficiency of the Australian regulatory system is that the APVMA is under the umbrella of the Department of Agriculture, the study says. This is unfortunate, because the priority of the Australian system is to provide chemicals for agricultural production, whereas protecting the environment is not a strong consideration.

Other concerns included the APVMAs processes that support the ongoing use of registered products after environmental or health concerns are raised, rather than removing those products from use.

Australian law states that there must be conclusive scientific evidence that a pesticide is unsafe before it can be removed from use. Testing the effects of a pesticide on humans and the environment is a long and expensive process, so its unsurprising that Australias banned pesticides list is substantially shorter than most other countries which stipulate that a pesticide must be proven safe before it can be sold.

The ad hoc, case-by-case and very slow chemical review process administered by APVMA has not effectively assessed or addressed chemical risks to the Great Barrier Reef, or elsewhere.

The scientists found Australian water quality guidelines for pesticides were badly out of date and updates had been severely delayed.

A related issue is the long delays between strong evidence of exceedance of guidelines in waters over long periods, as demonstrated via published monitoring studies, and regulatory or management action.

To adequately protect the Great Barrier Reef, given its marine protected area and world heritage status, both the special management provisions for the area already existing plus an effective national pesticide regulatory regime at least of the standard of the European Union are the minimum requirements.

Continued detections of above guidelines concentrations of pesticides and the conclusion that most basins of the Great Barrier Reef do not meet the current risk target lead us to conclude that, in general, pesticide regulation and management is, and has been, unsuccessful in the region.

The APVMA said in a statement it had not been provided with a copy of the journal article, nor were they approached by the authors of the article.

In Australia, we employ a weight-of-evidence, risk-based model to regulate pesticides. This model considers both the hazards posed by a product and the likely exposure of humans, animals and the environment to those hazards, the authority said.

The APVMA only registers chemical products where the risks can be mitigated through specific application and safety instructions on the product label. It is then the responsibility of state and territory governments to control the use of these products.

It said active constituents were assessed on the basis of their expected volume of use, expected exposure and the behaviour of any active constituents, and the potential harmful effects on wildlife and organisms.

This information helps to establish whether the risk to any of these organisms posed by the use of the product may be considered unacceptable or whether there are other concerns due to the behaviour of the substance in the environment.

Registered products are safe to use according to label directions.

Great Barrier Reef: scientists find high levels of pesticides and blast chemical regulator - The Guardian

Ravens players and coaches insist theres plenty of time left to build some chemistry and continuity on offense. But really, what else are they going to say?

It has to be extremely hard to evaluate the offense when theres so many missing or moving pieces. How can the team get a true read on the wide receivers when Ryan Mallett has struggled mightily and the teams de facto No. 2 quarterback, Dustin Vaughan, played so poorly in the preseason opener that he was quickly yanked and has since been released? Can we truly gauge whether the running game has improved when the first-team offensive line changes on a seemingly daily basis?

James Hurst started at right tackle in Thursdays preseason opener against the Washington Redskins. By Saturdays practice, he was at left guard, with recently signed Austin Howard inserted at right tackle. With Ronnie Stanley missing practice the past two days, Hurst is now at left tackle. Credit Hurst for his versatility, but it has to be difficult to develop chemistry with so much change up front.

The Ravens have 3 1/2 weeks before they open the regular season against the Cincinnati Bengals. If quarterback Joe Flacco, wide receiver Breshad Perriman and Stanley are back practicing at this time next week, there is still enough time. But thats a big if, as very little this summer has gone according to plan for the Ravens.

More on Mallett: It seems that every Ravens preseason game will be a referendum on Malletts ability as a quarterback. The increased scrutiny is understandable, given Flaccos back concerns and Colin Kaepernicks availability.

But have we really learned anything about Mallett this summer? His accuracy and decision-making have been issues his whole career, and his training camp has been a continuation of that. Throw in a revolving door of offensive linemen and a lot of uncertainty at wide receiver and tight end, and you have a struggling offense.

Make no mistake, the Ravens know Malletts flaws. But since drafting Tyrod Taylor in 2011, they have shown a reluctance to invest assets (money or high draft picks) in their backup-quarterback position.

Mallett makes $2 million, which is mid-level backup-quarterback money. Per contract data website Spotrac, 43 quarterbacks in the league will make more than Mallett this season. His salary this year is the same as that of Matt Barkley, Case Keenum, Mark Sanchez and Brandon Weeden, and less than that of guys like Landry Jones ($2.2 million), Matt Cassel ($2.6 million), Colt McCoy ($3 million) and former Raven Matt Schaub ($4.5 million).

With Flaccos durability, the Ravens clearly dont believe in spending much money on an upper-level backup quarterback. The only time Flacco has missed games was in 2015, when he tore up his knee in late November. The Ravens were 3-7 and going nowhere fast when the injury occurred.

So while they havent been punished yet for not investing a lot in a backup quarterback, a case could be made that the position should become a bigger priority with Flacco now 32 years old and having taken a ton of hits over the years.

Theories on White are wrong: The idea that the Ravens concocted the severity of the thumb injury to undrafted wide receiver Tim White so that they can stash him on injured reserve a narrative that has been strengthened by misinformed media members and fan speculation is nonsensical for myriad reasons.

First, White could have helped them this year as a wide receiver and returner. You never know how the final three weeks of the preseason would have played out, but White was in position to not only make the team but also have a role on Sundays. With jobs potentially on the line this year, no coach or executive is going to prioritize next season over the current one.

Second, you cant officially put players on IR without them having clear waivers after the final roster cutdown to 53 players, which follows the final preseason game. So there are absolutely no benefits right now in shutting White down. It doesnt give you roster flexibility.

Third, the Ravens are dealing with a staggering number of injuries right now, and the wide receiver position has been hit reasonably hard. Perriman and Kenny Bell have been sidelined since early in camp because of hamstring injuries. Since White was ruled out, Quincy Adeboyejo has gone down with a knee injury. The Ravens simply arent going to compound their injury situation by shutting down a good young player who could help them during the season.

Four, while stashing is frowned upon by the NFL, it happens pretty much everywhere. But nobody is stashing players after Week 1 of the preseason. Too much can happen over the rest of the preseason for teams to handcuff themselves with a rash decision after one game.

And one more quick point about White: The Ravens said the former Arizona State player is expected to miss the season. That doesnt mean hes not an option to be one of two players the Ravens place on IR with a designation to return later. But that doesnt need to be decided now.

Quick hits: Undrafted rookie running back Taquan Mizzell has been really impressive, and there should be a spot for him in the NFL, but I think it will be tough for him to crack the Ravens 53-man roster. The Ravens already have Danny Woodhead, and Mizzell has a pretty similar skill set. Im a little surprised the Ravens havent opened up a few roster spots by doing something with Bell and inside linebacker Lamar Louis, who are both dealing with injuries and not practicing. They could use a few more healthy bodies at certain positions. Tight end Maxx Williams deserves a ton of credit for persevering through a serious knee surgery and getting back onto the field this summer. But in watching him run, its still pretty clear that he has a ways to go. He has bulked up and gotten considerably stronger, so it will be interesting to see whether he becomes more of a blocking tight end, assuming hes on the season-opening roster. In about a month, second-year offensive lineman Matt Skura went from a guy I thought might not make the team to the teams top reserve at three positions. Im not sure the Ravens have seen enough in fullbacks Lorenzo Taliaferro or Ricky Ortiz to feel comfortable with either as the lead blocker in a key fourth-and-short situation. At least, not yet. Every time an NFL team loses a member of its front seven to a season-ending or significant injury, as the Detroit Lions recently did, I picture Ravens officials poring over that teams roster to see whether they have any excess offensive linemen who might intrigue them in a potential trade.

Tiffany Michelle Geliga, 35, was charged with two counts of sexual assault by a person 24 years of age or older on a 16 or 17-year-old victim, WFLA reported.

Police began investigating Geliga afterPort St. Lucie High School administrators told them that a 17-year-old students mother contacted the school to report that the teacher texted her son many times at odd hours.

The woman said she believed nothing happened between her son and Geliga but suspected that she had an inappropriate relationship with another student.

School officials questioned that 17-year-old boy, who admitted to having sex with Geliga two times in her car on separate occasions and met her off campus in late April or early May,WPTV reports.

He added that he also received late-night phone calls and text messages from Geliga.

Investigators said the victim met Geliga two months ago when she began tutoring him atIndian River State College in Port St. Lucie, the Palm Beach Post reported.

They reportedly started text messaging each other after the victim sent a message requesting Geligas assistance in making an introduction to a female student.

Police initiated a controlled phone call between the 17-year-old and Geliga in whichthey monitored their conversation.

On the call, Geliga told the student she had never done anything inappropriate with other students just you, and acknowledged that she had a sexual relationship with him. She then offered to foot the bill for a stay at a West Palm Beach hotel.

Geliga was released from the St. Lucie County Jail after she posted $30,000 bail Friday.

Geliga started teaching at Port St. Lucie High School back in August 2014 and is reportedly married with two children.
