The Nationals bullpen is a tire fire. Theyre about to add another tire. Per Jon Heyman of FanRag Sports, Washington is about to sign free agent reliever Francisco Rodriguez.

K-Rod was released by the Tigers last week after posting an ERA of 7.82 over 28 appearances this season. He has a 1.658 WHIP, is allowing 11.9 hits per nine innings and is posting his highest walk rate in five years. Also worth noting: the Detroit Friggin Tigers decided that he was not good enough to be in their bullpen.

So, yeah, good luck with that Washington.

Ive spent years arguing with people about team chemistry. You know the battle lines on all of that now: people who talk a lot about team chemistry tend to attribute winning or losing to good or bad chemistry, respectively. I tend to think that characterizing chemistry is a retroactive exercise in which teams that win are happy and then cite their happiness as the reason and vice versa. Jim Leyland agrees with me, for what its worth, so Im pretty happy with my take.

Not that Ill claim a monopoly on wisdom here. Ive never played on a professional baseball team. I dont know what its like to try to prepare to play baseball while surrounded by jackwagons who dont get along with anyone. I cant imagine that makes life easier. Indeed, based on the testimony of players I have spoken to, I will grant thatthere is at least some intangible yet real benefitif everyone is happy an gelling. I dismiss team chemistry arguments for the most part, but if I ran a team Id at least try to get rid of bad seeds if their bad seeding was not outweighed by seriously outstanding on-the-field play. You want your workers happy, folks.

All of which makes me wonder what the heck to do about this passage from Ken Rosenthals latest column. Its about the reeling San Francisco Giants. They have all kinds of issues their offense is putrid, their pitching isnt much better and theyve been without their ace most of the year but today Rosenthal looks at their team chemistry. Its a quiet and subdued clubhouse, he notes, and it has a lot of people wondering if something is wrong there. What could it be?

Sandoval, who was an often noisy and boisterous presence during his time with the club, departed as a free agent after that season. Pence has suffered a number of injuries in recent years and declined offensively, making it difficult for him to be as vocal as he was in the past. Some with the Giants muse that the team even misses Angel Pagan, who created an odd sort of unity because most of the players disliked him.

Read that last sentence again. And then go on with your talk about how team chemistry is a legitimate explanatory concept regarding what makes teams win or lose as opposed to a post-hoc rationalization of it.

Not that its not a good article overall. Theres some interesting stuff about the Giants bullpen culture. And, of course, we now know why no one signed Pagan last winter.

Giants ace Madison Bumgarner tossed three no-hit innings yesterday in his first minor league rehab start with the Giants Arizona Rookie League team. He struck out two and walked a guy, while sitting in the 88-91 m.p.h. range on his fastball.

Bumgarner, who is coming back from a sprained left AC joint in his shoulder suffered in a dirt bike accident in April, will return to San Francisco to throw a bullpen session and then go back on the road for more rehab games. Thats a lot of traveling, but the Giants obviously want to monitor his progress. At the moment hes expected to build up his strength for the next several weeks and, hopefully, return to the Giants rotation some time after the All-Star break.

Of course, there shouldnt be too much of a rush. The Giants have lost five in a row and 12 of 13 and currently sit in last place, 24.5 games behind the Dodgers. At this point Bumgarner rushing to rejoin the Giants is like an Australian soldier getting a wound dressed to hurry back to the Gallipoli Campaign.

One of the biggest things to watch in the upcoming Denver Broncos Training Camp is positional battles in various parts of the roster. Specifically, who will earn the right to start Week 1 at tight end. How quickly the veteran tight ends competing for that spot can gel with the quarterbacks will be vital in determining who gets the nod.

The tale of the Broncos season last year was a defense that kept the team in games and an offense that could not produce enough points to win them.

While all three tight ends bring their own unique skills to the table, the Broncos need for offense could drive them to select the tight end that helps put up points.

With both Trevor Siemian and Paxton Lynch expected to receive an equal share of first-teams reps in training camp, each tight end will need to show chemistry with both to separate themselves in the competition.

In Lynchs two starts last season, none of the tight ends on the roster logged a single reception, making it hard to judge which of the three he will feel most comfortable throwing to.

It should be noted that when Lynch entered the game in relief of the injured Siemian in Week 4, his only completion to a tight end was a 19 yard strike to Jeff Heuerman.

Virgil Green, the starter for most of the 2016 season, should get the first chance at proving he can be the Broncos starter for the 2017 season.

While Green, one of the longest-tenured Broncos, has more experience than his fellow tight ends on the roster, does that necessarily make him the best best choice for the Broncos as the starting tight end in Mike McCoys offense?

Unlike Gary Kubiaks run-heavy offense, which favored a blocking tight end, McCoy will look to get the tight ends involved in the scoring game. His success with Julius Thomas in his previous stint in Denver and with Antonio Gates andHunter Henry in San Diego.

If Trevor Siemian is named the Broncos starting quarterback, both Green and A.J. Derby could be the frontrunners for the starting position. Both showed good chemistry with Siemian in different parts of the 2016 season.

Green led the tight ends in receiving yards overall (237), but Derby finished within 100 yards of Green (160) despite being acquired midseason.

It wont necessarily be the best overall player who is named the starting tight end right away. The Broncos know they need offensive production to develop quickly if they hope to return to the playoffs in 2017.

Regardless of who is named the starter, head coach Vance Joseph has a positive take on all three tight ends competing for the starting spot on the roster:

Its a mixed-bag group. Its a big blocker in Green. Its a new move guy in Derby. Its a young guy in Heuerman. Its a group of great potential first of all. Its exciting to watch those guys go make plays. Our safeties are really, really good players, [T.J.] Ward and those guysso to beat those guys one on one, thats fun to see, Joseph said during OTAs

Pay close attention to training camp practices and early preseason games. The tight end who can put up yards and points from both quarterbacks could be starting Week 1 for the Broncos.

Quick chemistry with QBs vital in determining Broncos starting TE - Mile High Sports

WASHINGTON You might not know which chemical element in the Hope Diamond has the largest molecular mass, but an eighth-grader from Scottsdale does.

Isaiah Hazelwood faced that and other questions faced earlier this week when he squared off against other middle school students from around the country as part of the You be the Chemist National Challenge in Washington.

The lanky 13-year-old whos in the eighth grade at Basis Scottsdale won the state competition in February to advance to the nationals on Monday, competing against 41 other students representing 39 states, Puerto Rico and the District of Columbia.

The competition drew a total of 55,000 students at the local and state levels, according to a prepared statement from Dwayne Sattler, executive director of the Chemical Education Foundation, which sponsored the contest.

Students like Isaiah, who are excited about particular subject areas, certainly dive a little bit deeper and our teachers help work with them to foster that excitement, Basis Scottsdale Principal Kristen Jordison said by phone this week.

Between rounds, Isaiah spoke quietly and looked away during interviews until the conversation turned to chemistry. Then, he lit up.

Im excited about chemistry because it just tells us so much about how the world works and how we work, Isaiah said Monday.

The competition, sponsored by the Chemical Educational Foundation, featured four rounds of competition, with students eliminated in each round.

But unlike the more familiar spelling and geography bees, where individual students face the glare of the spotlight as they try to answer a question, the chemistry students remain seated on stage where they all saw the same question at once. Giant screens projected timed multiple-choice questions that the students answered using individual clickers.

-Cronkite News video by Emma Lockhart

All 42 students started in the first, preliminary round in a Washington hotel ballroom with the students in seated rows on the stage as educators, organizers, sponsors and others watched from round tables in the audience.

Im excited about the having completed the preliminary rounds however the questions are a bit harder than I expected, Isaiah said after one of the early rounds. Im not all that certain Ill get into a top four spot.

The questions, some of which were at the level of an AP class, were a challenge even for some teachers.

They are tough questions, said Kaitlyn Mandigo, a BASIS Scottsdale chemistry teacher who was in Washington for the competition. As a person with a chemistry degree, there were some that I really had to pause and think about.

Isaiah was able to survive and advance to the second round with 14 other students but did not make the next cut, down to four finalists.

Miss USA Kara McCullough, who has a bachelors degree in chemistry, spoke at the event and awarded the winning prize which included a calculator as well as a trophy to eventual champion, Anantahn Sadagopan, 13, from Massachusetts. He also won a $12,000 scholarship.

But for Isaiah, there was more to the trip than winning. And chemistry, surprisingly.

Coming here I was excited to see all of the monuments and memorials in D.C., he said this week. We may be staying here a few extra days to catch up on all of the memorials and monuments and buildings.

In a recent Chemical Reviews article, Spanish researchers have published the first exhaustive revision of the state-of-the-art methodologies underlying chemical search engines, named entity recognition and text mining systems.

The rapidly growing field of big data applications in biomedical research, together with the use of machine learning and artificial intelligence technologies for text data mining, has resulted in promising tools. The authors write, "This review is organised to serve as a practical guide to researchers entering in this field but also to help them to envision the next steps in this emerging data science field."

"Through the release of Gold Standard datasets and the organisation of several community challenge benchmark events, the Biological Text Mining Unit has played a critical role in the development and evaluation of current chemical text mining systems, as highlighted in this article," explains Martin Krallinger, head of the unit and co-first author of the review.

A huge amount of unstructured data

A considerable fraction of biomedically relevant data is only available in the form of unstructured data. This type of data includes rapidly growing scientific literature, medicinal chemistry patents, electronic health records and clinical trial documents. In fact, every year, over 20,000 new compounds are published in medicinal and biological chemistry journals.

Being able to transform unstructured biomedical research data into structured databases that can be more efficiently processed by machines or queried by humans is critical for a range of heterogeneous applications. These include the identification of new drug targets and chemical probes to validate/discard those new potential targets, re-purposing of approved drugs, the identification of adverse drug events or retrieval of systems biology associated with chemical-disease or chemical-gene networks.

As a therapeutic strategy to treat medical needs, chemical compounds constitute a key entity type of critical relevance for biomedical research. "The construction of large chemical knowledge bases, integrating chemical information with biological and clinical data, is crucial to identify and validate new therapeutic targets for unmet medical needs as well as to speed up the drug discovery process," says Julen Oyarzabal, director of Translational Sciences at CIMA and co-leader of this report.

Researchers review the state-of-the-art text mining technologies for chemistry - Phys.Org

The U.S. team was finalized after an intensive two-week Chemistry Olympiad Study Camp, sponsored by the American Chemical Society and held at the U.S. Air Force Academy in Colorado Springs.

The students are Steven Liu of Monta Vista High School in Cupertino, Calif.; Joshua Park of Lexington High School in Massachusetts; Harrison Wang of Hinsdale Central High School in Illinois; and Brendan Yap of Carmel High School in Indiana.

Jeffrey Shi of Marcellus High School in New York is the first alternate. Aniket Dehadrai of Oklahoma School of Science and Mathematics in Oklahoma City is the second alternate.

This is one of the strongest groups we have seen, says mentor Michael Danahy, a lecturer in chemistry at Bowdoin College. They came in really well prepared in all aspects of chemistry.

Liu says he has been preparing for this moment for years. Last year, I was the first alternate, and it was heartbreaking, he says. Going through the cycle twice really helped me grow and improve. I think thats what helped me make the team this year.

Yap says that participation in the study camp motivated him to change his intended college major from electrical engineering to chemistry or chemical engineering.

To be honest, Im still kind of stunned, says Park. Im going to be one of four people representing the U.S., and its a big responsibility. Im kind of nervous about that.

Wang is nothing short of optimistic. The U.S. team this year is really strong, and I want others to see how hard we work and how much time and effort weve put into this.

In addition to Danahy, the team will be accompanied by mentors Patrick Chan of Benjamin N. Cardozo High School in New York City and Christine Saber of Gannon University.

Eli Lilly (NYSE: LLY) has completed a $90 million expansion of its biotechnology R&D center in San Diego, added new automated synthesis equipment, and plans to build out its next-generation chemistry capabilities here over the next two years.

The new facility adds 180,000 square feet of space to Lillys laboratory in La Jollaa 145 percent increase for the site. The expansion features a soaring architectural faade intended to resemble DNA molecules during gel electrophoresis. During a dedication ceremony of the revamped facility Wednesday, David Ricks, chairman and CEO of the Indianapolis-based pharmaceutical giant, said the project is part of the $850 million capital spending plan that Lilly announced earlier this year.

This new space will help foster and accelerate the discovery and development of medicines within Lillys core therapeutic areas of immunology, diabetes, oncology, and neurodegeneration [particularly in Alzheimers disease], as well as our emerging areas of pain, said Tom Bumol, who oversees the San Diego site as Lillys senior vice president of biotechnology and immunology research.

Bumol said he has been part of the life sciences community in San Diego since Lilly acquired Applied Molecular Evolution in 2004 for roughly $400 million. The company later combined AMEs operations with SGX Pharmaceuticals, another San Diego biotech Lilly acquired in 2009 for $64 million.

The expansion will add new capabilities in small-molecule drug development to the labs existing expertise in biological drug development, Bumol said. The San Diego lab engineered the DNA for Ixekizumab (Taltz), an injectable monoclonal antibody drug that won FDA approval in March 2016 for treating psoriasis.

Several of Lillys current products and many of the new molecular entities in our research pipeline are biologics, Bumol said. Almost 60 percent of those molecules have been touched by the scientists and technology in our San Diego labs. As an example, another investigational molecule designed here, galcanezumab for migraine prevention, just finished three successful Phase 3 studies. The company is now planning to file for FDA approval.

The expanded facility also has the Lilly Life Science Studio, which includes equipment needed in automated organic synthesis for new chemical entities. The studio will enable researchers across the globe to remotely design, synthesize, and screen investigational molecules, using robotic equipment that can be programmed to run experiments overnight.

Today, Lillys San Diego lab has about 210 employees, and Bumol said he is looking to fill 30 or so openings this year. With the laboratory expansion, the facility can now accommodate 400 workers Bumol said.

Lilly Adds Chemistry Capabilities in San Diego Lab Expansion ... - Xconomy

This is my eighth summer in Australia. It took a little while to adapt to Christmas and New Year in the heat swapping the once obligatory novelty sweater for swimming togs but now it feels almost normal.

This summer has been different though. The country has been on fire.

For countless days beaches have been deserted, blue skies turned orangey-brown with smoke obscuring the summer sun, the eerie odour of burning bushlands heavy in the air.

Were used to bushfires in Australia, but this season the fires have been unprecedented. They started earlier than usual, their scale has been enormous, and theyve had devastating consequences. Thirty-three people have been killed, thousands of homes have been damaged or destroyed and at least 1 billion mammals, birds and reptiles are thought to have perished.

The bushfire season isnt over in Australia, but as heavy rain has finally dampened many of the blazes, weve entered a time for both sombre reflection and calls for action. Amidst increased public discourse on the links between the bushfires and climate change, questions have emerged about the role of the scientific community in the response to the bushfires. And of course, that means citizen scientists too.

Erin Roger, chair of the Australian Citizen Science Association(ACSA), thinks that citizen science can play a huge role in measuring the wide ranging impact of the bushfires, particularly because so many people want to know what they can do to help.

ACSAs role is as a voice for the community, a source of coordination and best practice advice, says Roger.Immediately following the catastrophic fires, we saw a number of call outs on social media this really garnered a community will to somehow contribute. I think theres huge potential for citizen science to tap into that.

Casey Kirchhoff, a PhD candidate at the University of New South Wales Centre for Ecosystem Science, was one of the people who lost her home in the bushfires. Returning to her property, just days after the fire came through, Kirchhoff was inspired to start a citizen science project; perhaps an unusual response to such a devastating event.

It definitely came from a bit of a strange place, says Kirchhoff. I really need something to occupy my mind at the moment. She was inspired when she saw some early signs of recovery in the bush. The whole thing was burnt out, so going back there and seeing some of the shoots coming through so quickly made me really happy.

Following conversations with colleagues, Kirchhoff launched Environment Recovery Project: Australian Bushfires, hosted on the citizen science platform iNaturalist. The aim is to encourage people to upload photographs taken in fire-affected areas (once its safe to return to the bush) so that scientists can better understand which species of plants and animals are returning and which remain threatened or even more tragically, which may be extinct.

For me, projects like this are especially important because they are inextricably linked with climate activism. They encourage people to directly observe the stark effects of bushfires that have been exacerbated by record temperatures and long periods of drought.

Kirchhoff believes that citizen scientists have an important role to play too. When people actually see things with their own eyes maybe they care about things a little more and are motivated to act and get other people to act as well. And that really does tie in with climate change and action on climate change, because when people start caring about the natural world, then they obviously want to protect it.

The images of green shoots on charcoal landscapes are incredibly hopeful, but I asked Kirchhoff if there was a risk that these images could be used to propagate a message that minimises the impacts of the bushfires. I think its really good for people to keep in mind that although it can be really positive to see the regeneration, theres also things out there that arent regenerating and things that wont be coming back, she says.

The team are not just calling for images of regrowth. Volunteers have uploaded tragic images of dead snakes, wombats and wallabies. Participants are actively encouraged to share any and all images taken in areas where the fire has passed through, along with careful annotations that describe the location and contents of each image. And theyre being particularly diligent in this project.

Usually on iNaturalist you dont get much in terms of a comment relating to an observation, but were getting really detailed notes, says Kirchhoff. People are going above and beyond and its really been great to see. If we could get more people doing that it would be fantastic because we could have more future activists on climate issues as well.

Dipping bread in a bowl of fresh, extra virgin olive oil ranks as one of the most pleasurable gastronomic experiences possible. But as this new Reactions video explains, theres more to this delicious and surprisingly healthy condiment than meets the eye.

Olive oil is a staple in many kitchens, yet its a condiment many of us take for granted. This delicious oil, in addition to bringing salads and bread to life, can be used in cooking, as an effective paint and grease remover, a remedy for ear wax, and even as hair conditioner.

But for those of us who use it in the kitchen with reckless abandon (raises hand), not all olive oil is created equallynor does it all taste the same. The American Chemical Society takes a look at some of the chemistry behind olive oil, including the best way to use it, why it draws bad LDL cholesterol from our bloodstreams, and how some manufacturers add unsavory ingredients to the olives during the extraction process. The ACS also talks to an expert who explains what we should be looking for in a high-grade, quality olive oil.

Armed with this information, youll be able to annoy your friends with your expansive knowledge of olive oil the next time a charcuterie board comes your way.

The Chemistry of Olive Oil Will Make You an Instant Food Snob - Gizmodo

You gotta exfoliate. The dead skin cells on your face dull your complexion, clog your pores, and cause breakoutsand sloughing them away is the first step to brighter and smoother skin. This is not news, right? Exfoliating is part of the basic skincare regimen.

The most common exfoliating products are textured scrubswhat are called physical exfoliants. But if you are feeling more serious than ever about your skincare regimen, we suggest you consider switching over to a chemical exfoliant. These work much deeper and more proactively than a superficial scrub that runs its full course in 15 seconds. (Doubly so if you are feeling serious about this routine being an anti-aging regimen.)

Chemical exfoliants range from straightforward skin brighteners to heavy-duty face peels. They help reverse things like hyperpigmentation (dark spots and discoloration), fine lines, and wrinkles, and fight clogged pores. And they do it far more effectively than most topical scrubs. (Scrubs do have some benefits of their ownwell get to that.)

To get more intel on chemical exfoliants, we rang up top-tier NYC dermatologist Michele Green. Here is what Green had to say about these acid-packed serums, masks, and peelsand she even provides expertise on the type of chemical exfoliant that will best suit your skin.

Dont be spooked by the term chemical here. It simply refers to the reactions that take place when these products encounter your skin. Acids are the most common chemical exfoliants, Green says, and they vary in strength and purpose.

These exfoliators gently penetrate the layers of the skin, breaking down dead skin cells through chemical reactions, explains Green. The shedding of dead skin cells can be dramatic or superficial depending on the type of exfoliant used and its strength. Many of these ingredients are derived from natural sources like fruits, and many of them also occur naturally in our own bodies.

You can tell that a product will act as a chemical exfoliant if its ingredients include things like:

AHAs: alpha hydroxy acids, such as lactic and glycolic acid. Tthese work well as skin brighteners, and are especially useful for people without a major skin malady besides an interest in having fresher complexion and smoother skin tones.

BHAs: beta hydroxy acids, like salicylic acid. These are great for acne-prone individuals since they better penetrate the skin and exfoliate the pores; they are often anti-inflammatory too, calming redness and swelling associated with breakouts.

TCAs: trichloroacetic acids. These provide a deeper peel, and are better for reversing hyperpigmentation, signs of aging, melasma, and even scarring.

Fruit enzymes: like papaya or pear extract. People with sensitive skin might have a hard time with AHAs, BHAs, and TCAs, but luckily, fruit enzymes work more in their favor: Fruit enzymes provide a gentler exfoliation, notes Green. The enzymes break down the keratin proteins that are within those upper, old skin cells, revealing fresh, new, and brighter cells from beneath the surface.

Were still fans of physical exfoliationthat is, face scrubs and body buffers. They smooth your skin as if you spent a day rolling around in the sand. And some of them are gentle enough that they can be used daily.

The major benefit of chemical exfoliants, says Green, is that they can remove several layers of dead skin with one application, whereas scrubs are typically only targeting that superficial, outermost layer.

Another point in favor of chemical exfoliants is that they tend to be better for people with sensitive skin, who typically suffer from the friction of physical scrubs. A lightweight fruit enzyme peeling mask will do wonders for sensitive skin, Green says, improving skin tone and texture and reducing hyperpigmentation and superficial wrinkles.

The main risk is excessive use. Green says that you shouldnt be using these products daily; you need to give your skin cells time to turn over before you peel away the new top layer. Too much exfoliation, with scrubs or chemicals, will only lead to rashes, redness, dryness, and breakouts. Everyones skin is different, but 1-2 times a week is a good baseline to avoid over-exfoliating.

Lactic acid and pear extract combine to smooth wrinkles, fine lines, and to rid of dark spots and large pores.

Watch your skin age in reversethis serum fights sun damage, wrinkles, dark spots, and more.

Papaya extract leads the charge in this wash-away peeling mask. Do it twice a week after cleansing, before bed: wash away after 5-10 minutes and follow with a overnight moisturizing cream.

A heavy-duty peeling serum that deploys lactic acid to dissolve dead skin and reveal a healthy, bright complexion beneath.

The combination of glycolic and lactic acids fuels REN's exfoliating mask, which you can use twice a week for 10 minutes. (Apply to clean, dry skin, ideally before bed.)

Swipe one of these wipes across clean skin to zap dead cells and promote the quick turnover of clear, healthy skin. It's more of a skin-toning step than the full-on application of a serum or mask, but it's every bit as effective.

With a high concentration of TCA, plus the addition of salicylic acid, you've got yourself one helluva face peel. This stuff helps remove the appearance of fine lines, hyperpigmentation, and even scars; it's one of the best anti-aging products of the lot.

The combined effects of chemical contamination by road salt and invasive species can harm native amphibians, according to researchers at Binghamton University, State University of New York.

During the winter, Binghamton and similar areas throughout the United States use a lot of salt to clear icy roads, but what effect does it have on wildlife? George Meindl, visiting assistant professor of environmental studies at Binghamton University, worked with a team of undergraduate students in his plant ecology course to examine how water chemistry changes due to invasive plant leaf litter leachates and road salt, and how it influences the development and survival of the native Northern leopard frog, Lithobates pipiens, and the non-native African clawed frog, Xenopus laevis.

They discovered that the non-native amphibians were more tolerant to chemical changes than the native amphibians, suggesting that the non-native amphibian species might have a competitive advantage when introduced into a new, disturbed environment.

Recently, there has been widespread chemical alteration of natural environments due to human activity, especially with the use of road salt. While road salt is commonly used to keep roads safe during the winter months, it also has negative effects on the surrounding environment and animals, according to Meindls research. Aquatic ecosystems, where frogs tend to reside, are especially susceptible to chemical changes, including those caused by road salt runoff and invasive plant species.

People are changing natural environments in many ways, so it is important that we understand how these changes affect wild populations of plants and animals, in order to better protect them, Meindl said. Using natural areas on campus, my students and I can ask how people are altering natural ecosystems, and then think of better management strategies to make sure these places arent completely degraded.

To test the environmental effects, researchers exposed the frog eggs to metal treatment solutions (i.e., calcium, potassium and manganese), which mimicked documented differences between native and invasive wetland plant species leaf tissues. Researchers first measured the amount of time it took for the eggs to hatch in solutions representing native and invasive plant leachates, and then they exposed the tadpoles to a lethal concentration of sodium chloride and recorded tadpole survival.

Essentially, researchers determined that increased metal concentrations resulted in a lower susceptibility to salt for non-native tadpoles. However, increased metal concentrations caused the native tadpoles to have a higher susceptibility to salt, causing an accelerated time to death.

Meindl and his students chose to focus on the native Northern leopard frog and the non-native African clawed frog for this research to determine whether the salt tolerance of native and non-native animals was differently affected by environmental changes caused by invasive plants.

In addition to studying how chemical contamination can affect amphibians generally, we also wanted to know if native vs. non-native amphibians would respond differently to these stressors, he said. For example, if non-native species are less likely to be negatively impacted by chemical contamination compared to native species, then contaminants might actually encourage the spread of invasive species by giving them a competitive advantage over native species, Meindl said. Perhaps not surprisingly, we found that the non-native African clawed frog was more tolerant to chemical changes compared to the Northern leopard frog, suggesting chemical contamination (e.g., due to road salts or invasive plant species) may facilitate future invasions by non-native species in aquatic ecosystems.

However, invasive species and road salts arent the only factors causing negative environmental effects, Meindl said. He hopes that the results from this study will influence people to focus more on the safety of the environment and the steps they can take to improve it.

Invasive species and road salts are just some of many ways that people are modifying the chemistry of the environment, along with extraction and burning of fossil fuels, plastic pollution, disposal of pharmaceuticals, excessive fertilizer use, etc., Meindl said. A great challenge is understanding how all of these stressors affect the natural environment, and then using this information to guide policy development that protects our planets natural resources. Studies like this will help to generate data that can guide more responsible resource use and behavior by people.

The paper, Exposure to metals (Ca, K, Mn) and road salt (NaCl) differentially affect development and survival in two model amphibians, was published in Chemistry and Ecology.

Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron and electron - come together in trillions of combinations to form ... everything. In this inaugural episode of Crash Course Chemistry, we start out with one of the biggest ideas in chemistry ever - stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.

CHEM0821. Chemistry of Wine. 3 Credit Hours.

Wine has occupied a central role in human culture. In our exploration of the science of wine we will learn why wine was the beverage of choice through the ages, why a bottle of wine can range from $2 to $2,000, how wine is made, what makes a good/bad wine, how is white different from red, and how we know what is in a bottle of wine. The course begins with a large scale fermentation of red and white wine and will continue with team-based analyses of the two month process of turning grape juice into wine. Many aspects of the production and consumption of wine will be addressed in this course. NOTE: This course fulfills a Science & Technology (GS) requirement for students under GenEd and the Science & Technology Second Level (SB) requirement for students under Core.

CHEM0838. Nature Has No Reverse. 3 Credit Hours.

Rapid advances in modern science often tend to conceal the "forest in the trees," but we all need enough familiarity with the "scientific method" to make informed judgments as citizens and voters. This course will take you on a journey through the history of science, with stops at the Second Law of Thermodynamics, the "revolution" of fire, the rational basis of life, energy as the universal currency and changes in the universe around us. We will end with that most disturbing of paradoxes: the certainty of uncertainty. Each week includes both lecture and hands-on demonstration/practicum. NOTE: This course fulfills a Science & Technology (GS) requirement for students under GenEd and the Science & Technology Second Level (SB) requirement for students under Core.

CHEM1055. Introduction to Problem Solving and Logical Thinking for Pre-Medical Post-Baccalaureates. 1 Credit Hour.

The ability to solve problems and think logically is essential for success in health professions schools because health professionals must be able to put together patient symptoms, test results, and current research to determine the best course of action for the patient in question. As a result, entrance exams for health professions schools test the ability to think and solve problems logically. However, the techniques of good problem solving are rarely explicitly taught at any point in a student's education, and science majors rarely take logic courses. This course seeks to fill that gap in a way that is geared specifically toward what is needed for pre-health students to succeed in their classes and on standardized tests. This course teaches students good problem-solving techniques and the basics of deductive and inductive logic. The students will spend class time practicing and applying the techniques and principles they are taught, either individually or in pairs/groups. This design will enable them to develop their skills of problem solving and logical thinking so that they can apply them not only to their classes, but to entrance exams for professional school and the practice of their profession as well.

NBA teams change every offseason, but the LA Clippers roster experienced one of the most drastic (if not the most drastic) shake-ups in the league this summer.

All-Stars Kahwi Leonard and Paul George made the move to LA along with veteran roleplayers Maurice Harkless, Patrick Patterson, and Rodney McGruder. Despite all these new faces, the team already looks comfortable playing, and more importantly, winning together.

Ramona Shelbourne of ESPN received the following information from head coach Doc Rivers:

Skeptics may claim that Rivers is exaggerating, but with 80 games left in the regular season, this is entirely possible. Plus, who knows players better than their coach?

With George out, Lou Williams becomes the Clippers next best scorer. He played 36 minutes and 43 seconds in the season opener, going 8/14 from the field for 21 points, five rebounds and seven assists. Leonard played 31 minutes and 11 seconds and hit 10/19 field goals for 30 points, six rebounds and five assists. Leonards three-point shot was faulty, as he hit just 1/5, but his 9/10 shooting from the charity stripe was appreciated.

Both Williams and Leonard can move the ball to the rest of the team and take smart shots, making the LAs offense successful even without George. In fact, the Clippers ball-movement has the potential to be the best its ever been, all thanks to the trust each player has for the next.

Leonard trusted his teammates enough to rack up a career-high nine assists against the Warriors Thursday night.

Other players on the roster such as Montrezl Harrell, Patterson andLandry Shamet may even start to carry some of the offensive load that Leonard and Williams have been expected to share.

Each players ability to accept their role will also grow the teams chemistry. The more comfortable each player is with their job, the more comfortable and consistent the teams offense and defense will be.

Patrick Beverley knows that his energy on defense is a huge asset, while players like Patterson and Harkless have accepted their roles as rotation players. Harkless started in 53 games for the Portland Trail Blazers last season but looks comfortable on both ends of the court coming off the bench. He is as good of a backup small forward as any.

There are a lot of NBA fans and personalities who have high hopes for the LA Clippers this year, and no doubt, their growing chemistry will help the team reach their championship goal.

The LA Clippers team chemistry appears to be on the rise - Clipperholics

Coach Dusan Ancich said his Villa Park football program returned from its team-bonding trip to Hawaii closer than ever before. But that chemistry will be tested after three talented transfers recently arrived from Corona High.

The Spartans have added USC cornerback commit Marcus Johnson (5-10, 175), linebacker/running back Zechariah Holifield (6-0, 220) and rising quarterback Shane Illingworth, a 6-foot-6, 225-pound sophomore, in recent days.

Johnson and Holifield are seniors who are moving into the Villa Park area so they could be eligible soon, Ancich said. Illingworth will observe the CIF-Southern Sections sit-out period, so look for junior Paul Piferi (6-5, 198) to remain the starter until at least until Oct. 6.

One of the lesser-publicized effects of transfers is the displacement of established players, which in turn could challenge team chemistry.

Ancich said the best 11 players will play for the Spartans (1-0), who take on host Redondo (0-1) on Friday.

We have two Division I quarterbacks, Ancich said. If everybody gets cleared, does things right, above board (and) we keep our team bonding and philosophy, it should be fun. Its a great surprise for us.

The Illingworth family is familiar with Ancichs coaching philosophy. Shanes cousin, Devon, played defensive end for the Spartans. His father played for Ancichs father, Marijon, at Tustin.

Everybody is treated the same, Dusan Ancich said. We give a depth chart every week. Its always the best 11 (who start). Thats just a black-and-white deal.

THOUGHTS ON HOUSTON

All of the high schools in the Houston area have canceled their Week 1 games because of the damage from Hurricane Harvey.

If displaced families arrive in the Southern Section, students could receive a hardship waiver to gain eligibility, section spokesman Thom Simmons said Monday.

Former El Dorado quarterback Kane Wilson was displaced by Hurricane Katrina in 2005 before arriving at the O.C. school as a freshman.

NOTES

La Habra and Yorba Linda are among the area teams that have moved practices Tuesday and Wednesday to the evening because of the expected heat wave.

Sonora finished 0-10 last season but opened with a 19-8 win against visiting Whittier.

Raiders coach Daniel Morales praised several players, including running back/linebacker Chandler Thompson and quarterback Ryan Martinez. Our defense played really tough, Morales said. I was so happy how they were challenged in our own territory quite a few times but didnt break.

Cal commit Chigozie Anusiem had four receptions for 87 yards and a touchdown and also played defense and special teams.

La Habra (0-1) is looking to bounce back from a 35-7 loss at Upland that Highlanders coach Frank Mazzotta called humbling. We have to get a lot better in a hurry, said Mazzotta, whose team plays host to Tesoro on Friday.

Tesoro coach Matt Poston said sophomore Kyle Schaefers helped the Titans as they nearly upset Edison before losing 48-47. He had 90-yard kickoff return for a touchdown and played well at cornerback.

Mission Viejo plays host to the Brothers in Arms Classic on Thursday through Saturday. Servite plays American Fork of Utah on Friday at 5 p.m. while the Diablos take on former CIF-SS rival Vista Murrieta at 8 p.m. American Fork is nicknamed the Cavemen.

Reigning CIF Division 1 champion St. John Bosco (0-1) plays Garces of Bakersfield on Saturday at 8 p.m. at Mission Viejo.

Notes: Villa Park hopes to keep chemistry grade high after transfers - OCRegister

Antoine Lavoisier gave oxygen its name, from the Greek words for acid-former. But that wasnt his only contribution to scientific understanding of what it does.

Born August 26, 1743, Lavoisier is considered the father of modern chemistry, according to University of Missouri Libraries. He was one of the first people to relate chemistry to the science of bodies, physiology, and study what we now call metabolism and respiration. One of his most memorable proofs that bodies underwent some of the same processes as the world around them was the time he froze a guinea pig.

Oxygen was first isolated by Joseph Priestley, a British chemist studying air, in 1774. Priestley called it dephlogisticated air, because he thought it was pure air that lacked phlogiston, an element that eighteenth-century scientists thought was produced by something burning but was also present in normal air.

Lavoisier didnt think that Priestley was right about phlogiston, prompting a long-running battle. Lavoisier didnt believe Priestley because of his own groundbreaking approach to chemistry. Lavoisier believed that matteridentified by weightwould be conserved through any reaction, writes Chemical History. Today this is known as the law of conservation of mass. What it means is that the same amount of matter that goes into a chemical reaction comes out of it. This central belief led him to study how the gases present in air related to fire and to breathing.Writing for io9, Esther Inglis-Arkell explains how this led Lavoisier to torment the poor rodent.

Lavoisier noticed that, just like a fire, people and animals seemed to warm themselves. Also like a fire, if people stayed in an unventilated room, they would eventually transform the air into a gas that smothered them. Lavoisier realized that the two processes, a fire burning and people breathing, were equivalent. Although he couldn't prove the chemistry involved, he could prove the basic physics. One of the main problems with his theory was that, unlike fire, animal-produced heat was so minor. How could it be measured?

Guinea pigs, which are native to modern Peru, had been in Europe for at least a few hundred years as pets for wealthy Europeans,writesMaev Kennedy forThe Guardian. Where Lavoisier got the guinea pig he used in the worlds first animal calorimeter remains a mystery. To measure the heat that was produced by breathing, he placed a guinea pig in a bucket that was nested inside another bucket filled with ice. The ice bucket was in turn nested in a bucket filled with snowwhich was just there to insulate the ice, writes Inglis-Arkells. The guinea pig didn't freeze to death, but was presumably pretty cold surrounded by all that ice.

Lavoisier collected the melted water, and when he at last got about a kilogram of it, calculated that the melting of the ice required about 80 kilocalories of energy from the guinea pig, she writes. He believed that the energy came from a process known as respiration, which turned oxygen into carbon dioxide and heat, the same way a burning piece of wood might.

Through this experiment, Lavoisier was able to demonstrate that respiration was a form of slow combustion, writes the University of Missouri Libraries. He continued exploring the ways that chemistry shapes bodies, even drawing links between food and metabolism, until his untimely death by beheading in 1794, during the French Revolution.

The Father of Modern Chemistry Proved Respiration Occurred by Freezing a Guinea Pig - Smithsonian

As for Wang herself, she said she genuinely enjoyed working in the sciences, but still felt her fate lay elsewhere. I like research, but I realized that someone else could be doing that research, with my writing I felt like I could be the only one doing that, she said.

In addition to the books humor, reviewers have noted Wangs choice to keep her narrator nameless. Wang explained that the decision to do so was a deliberate one. When I think of a name it is very specific to the character and I didnt want that to happen, Wang said. Would I name her something Chinese or something American? I didnt want to deal with that.

Juggling multiple identities is something Wang has a bit of experience in. Born in China, she and her family moved to Australia when she was 7 and later moved to Canada and then eventually to the United States. When I write characters that are not open, its because Im not necessarily that open in terms of opening up to new people, Wang said. I made her like that in that she is just very lonely. And when you are lonely, you are not used to telling people how you feel.

Wang added that she has been a bit taken aback at how mean many readers and reviewers said they thought her narrators parents were. Noting that while her books fictional parents did have high standards and did not always understand their daughter (especially as she waffled in regards to her studies), they were not uncaring.

When you are an immigrant parent, Do I want to make my child happy? is not a question you always ask, Wang said. Its I need to feed her. I need to put a roof over her head. I need to make sure she has health insurance. My point is not to vilify them.

That view of family also shaped how Wang developed her narrators journey and subsequent contrariness. Its not the traditional rebel story. Its not like Im going to go travel to find myself or I am going to join a band.' Because everyone I know rebels quietly, she said. Its not F**k you, parents. Im just going to leave the country.' Its doing really tiny things. Because first, my parents would kill me if I did that and also, how am I going to get health insurance if I do that?

New Hanover County Commissioners adopted a resolution Monday calling on Chemours to stop production of GenX. Brunswick County Commissioners adopted a resolution the same day -- asking Chemours to stop the discharge of the GenX chemical into the Cape Fear River. Thats largely because there is still a lot about GenX that we dont know. Its all about chemistry. Which means for many of us, it can be somewhat difficult to grasp.

As a scientist, I rely on data, to inform my approaches, and my evaluations, and I dont have the data yet.

Dr. Susanne Brander is a toxicologist at UNC Wilmington.

She says to understand GenX, one needs to look at its predecessor.

And so the only way to have an idea of what could be expected from exposure to a chemical like that is to look at what is known about a similar chemical, and there has been a lot of talk about how GenX was the replacement for another chemical known as C8, also known as Perfluorooctanoic acid. A PFOA.

C8 is a confirmed carcinogen. Its been linked to a wide range of diseases and cancers. Thats why GenX was developed. C8 is a long chain of carbonfluorine bonds. In GenX chemists added an oxygen atom to the middle of the chain. The thinking was this would make the compound less persistent, and it would pass through the body more quickly.

Dr. Phillippe Grandjean is with the Harvard University School of Public Health, and also chair of Environmental Health at the University of Southern Denmark.

We know that they appear to have a short half-life meaning they are eliminated very rapidly. But the fact of the matter is yes they do leave the bloodstream, but that is because they are accumulated in the body, the liver the kidneys the lungs, and so just because some of them appear to disappear from the blood rapidly, that may not indicate that they have disappeared from the body as a whole.

He says GenX is easily absorbed.

So if you drink contaminated water these compounds will rapidly move into your bloodstream and be circulated so that they can reach all the organs of the body. We also know that these compounds can cause liver cancer, in rodents.

Its when the GenX molecule attaches to other cells, that health issues can arise, albeit years down the road. Dr. Larry Cahoon is with UNC Wilmington.

This is a molecule, GenX and its congeners, that is going to tend to bind to cell membranes including some of the receptors that normally would bind with the hormone molecules or some of the other signaling molecules.

And, Cahoon says, they are resilient.

These compounds dont break down. Biologically they are not broken down. Once they are loose in the environment, they are loose in the environment and thats it. You are not going to get rid of them, these compounds are persistent as they possibly could be.

Again, Dr. Grandjean.

So this is very parallel to what we knew about PFOA, C8, in the 1990s, and my concern is that if these new GenX compounds if they have properties, I would be concerned that there might be additional toxic effects.

The levels of GenX in the Cape Fear River remain a mystery. This week the states Department of Environmental Quality began a series of tests at 13 locations between the Chemours facility, and Wilmington. Those results should be available in a few weeks.

GenX: A Question Of Chemistry - WHQR

My dad was a chemical engineer. In spite of that, I have a befuddled relationship with chemistry.

Its not love/hate, because I dont know enough about the elements to love or hate them. I took only one class as a senior in high school, but had been forewarned by my companions at my all-girls academy that the class was boring. Furthermore, it was taught by a quiet-spoken nun who was beyond retirement. I passed, barely.

I skirted chemistry in college by favoring liberal arts over science and was well into my gardening years before I realized that a little more knowledge of the periodic table would be helpful in knowing the connection between phosphorus and nitrogen, and whether potash and potassium (also in the NPK of garden fertilizer nomenclature) are the same. I regretted not understanding more.

Back in the 1970s, I discovered Monsantos Round-up was a powerful weed killer. I also learned it was a target of the organic homesteaders movement that I espoused. I quickly championed the harm that such chemicals can do to health. Reading Rachel Carsons discovery of the near-demise of the Bald Eagle because of DDT, I realized we have lived for thousands of years without plastic, flame retardant pajamas and Teflon non-stick pans. Why bother with such harmful chemicals now? I was a fervent anti-chemical activist.

I first learned the term from a teacher friend at Marian University when they established a green chemistry program. The EPA defines the practice of green chemistry as designing chemical products that are fully effective with little or no toxicity to either humans or the environment. Extraordinary! I wished I could have learned that kind of science. Its a win-win.

To that end, I have been trying to make up for my lack of basic knowledge about chemicals and their effects on humans and the earth. A three-part webinar starts this week that I am excited to see. Perhaps I will be enlightened on some of the classes of chemicals that have remained so foreign to me.

The three part series, called Six Classes, has a goal of helping consumers reduce the use of harmful chemicals by teaching us what these common chemicals are and how they affect our everyday life. It is offered free by the Green Science Policy Institute whose mission is to educate and build partnerships among scientists, regulators, businesses and public interest groups to develop innovative solutions for reducing harmful chemicals in products.

The webinars are based on what the Institute has established as six classes of harmful chemicals: highly fluorinated chemicals, antimicrobials, flame-retardants, bisphenols and phthalates, solvents and certain metals. The hour-long webinars will feature a short video on each class of chemicals (two per webinar) along with discussions with scientists and thought leaders. The webinars will share info about the toxicity of these chemicals, where they are used in our daily lives, why they are harmful and how we can avoid them.

Starting tomorrow, Thursday, June 22, and continuing the following two Thursdays, the webinars will be available three times each day. For more info and to register visit t.co/uAL2I5sb8t, or contact the Institute at 510-898-1704 or Laura@GreenSciencePolicy.org. I plan to learn a lot about toxic chemicals and green chemistry.

My dad, the chemical engineer, would be so proud of me.

Lynn Jenkins lives in rural Zionsville, where she is learning to live green. Email her at LJenks@tds.net.

What the heck is 'green chemistry?' - timessentinel.com

Willie Geist says the romantic relationship that developed between his MSNBC colleaguesJoe ScarboroughandMika Brzezinski who got together in 2016 and then engaged this May was a natural progression.

You had two single people, I think they always had a good relationship, they always had good chemistry, so I was not surprised by it. I was happy for them, Geist told Andy Cohen on Mondays episode of Watch What Happens Live.

When Cohen vivaciously added that the sexual chemistry was always crackling between them, Geist wholeheartedly agreed: And on the air! On the air you saw it.

Geist said the wedding is going to be a big fancy thing and that hed be there but didnt elaborate on the pairs plans.

Geist made an appearance on the May 4 edition of Morning Joe just hours after Page Six broke the news that the couple had gotten engaged and he was a little less direct about the impending nuptials. After one panelist offered up congratulations to the couple, Geist playfully added, Numbers have been up lately. Show is going well!

Scarborough, 54, popped the question toBrzezinski in Mayduring a romantic vacation to the south of France for her 50th birthday. Mika turned 50 and realized she wanted to move forward with her life and spend every minute with Joe, and not just at work, a source close to Brzezinski dished at the time.

Page Six exclusively revealed in June 2016 that the pair was involved in a hush-hush romance after Brzezinski and her husband of more than two decades divorced. This will be twice-divorced Scarboroughs third marriage.

Willie Geist: You could see Mika and Joe's chemistry on-air - Page Six

UPDATED: Tue., June 20, 2017, 9:07 p.m.

Its still early in the season, but one trait the Spokane Indians are demonstrating is the power of chemistry. No, not the academic version of chemistry taught in high school or college, but something more like the intangible internal feeling that distinguishes a typical team from a family team.

This was seen throughout the Indians five-game season-opening home stand against Boise.

Its the kind of unique quality that brings a team together when its trailing late in a game. It comes together to use chemistry to make deficits shrink. They simply refuse to quit.

Spokane manager Matt Hagen said the teams belief in itself has been one of the things that has really stood out in the first week.

We really do have a good team chemistry, especially for the first series of the year, Hagen said.

And thats something he said will be helpful later in the summer.

At some point this season, well be getting some players in from the draft and my hope is that those guys can jump right into what we have going on already and that theyll feel right at home, he said.

Aside from the physical challenges related to the daily grind of a baseball schedule, this level of baseball can be tough from a players perspective because many of these players are not only young, but inexperienced in the rigors of professional baseball. Ten of the Indians are 20 years old or younger, giving Spokane one of the youngest teams in the Northwest League.

And none are from here. Some arent even from the United States. With players from Nevada to Nicaragua, theyre a long way from home and spending all of their days with people theyve basically just met.

Spokane infielder Kole Enright, from Florida, said thats part of what has made the team closer.

I love the guys we have from Venezuela, the Dominican Republic and from Nicaragua, he said. Were a team. Thats part of what you sign up for when youre coming into a diverse sport like baseball.

Its a closeness that was even seen during the teams opening-night game. Down 4-0 entering the sixth inning, the Indians battled and fought to tie the game in the seventh at 4-4.

After the game, several players said they knew theyd come back, even though the Indians eventually lost 5-4. They talked about bonding during earlier games in the Arizona League.

It was evident again in Sundays doubleheader.

In the first game, the Indians lost 3-1. The following game, the Spokane offense exploded for seven runs in the first inning en route to a 10-0 win.

After the game, Indians catcher Isaias Quiroz said, Were a big, energetic team. Were always on each others backs, helping each other out. Doesnt matter if were down by 10 or up by 10, were always going to have each others back. We wont let each other ever quit.

That never-say-die attitude surfaced again in Mondays final game of the series against Boise.

Heading into the seventh inning, the Indians trailed 4-1. A few hits later, the Indians tied it up and then added an eighth-inning Yohel Pozo home run.

That is when the teams character was tested again. After a leadoff single to open the ninth, Boise clubbed a potential heartbreaking ninth-inning two-run home run to put the Hawks up 6-5.

How did the Indians approach the bottom of the ninth?

With a single. Then a game-tying triple. That was followed by a single to complete the ninth-inning walk-off win over Boise, 7-6.

The players piled on each other.

Cole Ragans, starting pitcher and the Texas Rangers eighth-ranked prospect, said this group of guys already feels like a team.

Thats what were made of, he said. This is what everyone should expect of us. Most of us have played with together in the AZL so we know what to expect from each other. We like each other and were gonna come out and play like that every game down to the last pitch.

Spokane catcher Clay Middleton agreed.

We just dont give up, he said as the team celebrated around him. This is a relentless group very, very relentless. This team is never out of the fight. We believe in each other.
