German Astronomical Society (AG) publishes this year's award winners

During the yearly major fall meeting, the German Astronomical Society awards internationally renowned prizes to individuals who have made outstanding contributions in astronomy. The awards recognize both scientific activities and achievements in the field of public outreach and education. Karl-Schwarzschild-Medal for Sandra Moore Faber

The highest honour in Germany for astronomical research, the Karl Schwarzschild Medal of the Astronomical Society will be awarded this year to the astrophysicist Sandra Moore Faber of the University of California, Santa Cruz.

"Sandy Faber has delivered in her more than four decades of research fundamental contributions to understanding the formation and evolution of galaxies, and she has significantly influenced observational cosmology" says Prof. Dr. Andreas Burkert, President of the German Astronomical Society. Of particular importance is her pioneering work on the mysterious cold dark matter, which is crucial for understanding the emergence of the large-scale structure in the universe and galaxy formation. Similarly fundamental has been her research on supermassive black holes at the centers of galaxies. Students of astronomy are familiar with her name through the well-known Faber-Jackson relation, which relates the orbital velocities of stars in galactic disks to the total luminosity of the galaxies. This relation is a useful tool to determine the distances of galaxies and to understand the structure of disk galaxies like our Milky Way. In addition, Sandy Faber has made significant achievements in the development of new instruments for astronomical observations, including in particular important work for the famous Hubble Space Telescope and the first 10m-class telescope in the world, the Keck Telescope on Mauna Kea, Hawaii.

Awards for successful young scientists

Cecilia Scannapieco of the Leibniz-Institute for Astrophysics Potsdam (AIP) will receive the 2012 Biermann Prize. Since her PhD in 2006 at the University of Buenos Aires, the Argentinian astrophysicist has been working in Germany. Her internationally acclaimed theoretical work and advanced modelling of the gas physics in high-resolution computer simulations have provided important new insights into the origin and evolution of spiral galaxies, and how these galaxies were able to form large, thin galactic disks like that in the Milky Way. Only six years after her PhD, Cecilia Scannapieco has already established herself as an international expert.

The Dissertation Award of the Astronomical Society goes this year to Julius Donnert from the Institute for Radio Astronomy in Bologna. The winner is honoured for his outstanding dissertation on magnetic fields and cosmic radiation in galaxy clusters. He completed his dissertation at the University Observatory Munich under the supervision of Harald Lesch. The publication of his scientific results has received a lot of attention in the scientific community.

Brgel-Prize goes to Hermann-Michael Hahn

The German Astronomical Society awards extend beyond active researchers. Media and outreach activities are also recognized regularly by the Society. For the first time since 2009, the AG will award the Bruno H. Brgel Prize for outstanding German-language popular depictions in the media. Hermann Michael Hahn from Cologne receives the award for his broad range of activities in particular in presenting basic skills in aerospace and astronomy to a wide audience. The award winner has been a journalist since 1968 and is known for his numerous books, articles for leading newspapers, public lectures and activities in radio and television.

Renton developing Aerospace Training Center

Posted on August 4, 2012 by Danzig

With $2.5 million from the state, the City of Renton is developing the Renton Aerospace Training Center at its airport where Renton Technical College will train much-needed aerospace workers.

An architect has been hired to determine whether it makes sense to remodel the former Renton Chamber of Commerce headquarters on Rainier Avenue for the training center or to build new after tearing down the roughly 50-year-old building.

RTC would train 120 students per quarter, with a staff of four faculty members two full-time and two part-time, according to RTC President Steve Hanson. RTC would offer Aerospace Manufacturing Assembly Mechanic certificate training, The college established the program in 2011 to train assembly mechanics.

The college may offer short-term training in areas such as tooling and quality assurance, he said. The Precision Machining Technologies Program will remain on the main campus.

RTC will use a portion of a $2.1 million Air Washington grant the Department of Labor to support the expansion of the new center. Increasing the capacity to train workers is a key priority of the grant, he said.

Renton led the lobbying efforts to obtain the $2.5 million from the states capital budget, in partnership with RTC and The Boeing Co., to develop the center, said Suzanne Dale Estey, the citys economic development director.

We want to make sure this is a legacy project for the aerospace industry and the community, said Dale Estey, who added the citys sense is that the aerospace industry is in Renton for decades to come.

Boeing is already producing its 737 at the Renton plant at record levels and that rate will continue to increase, to 42 planes, if not higher. At the same time Boeing is anticipating an increase in retirees, so it will need to replace them with new trained workers.

The goal is to complete the design in six months, then begin construction early next year, with the building ready to accept its first students in 2014, Dale Estey said.

The training center is part of a plan Dale Estey drafted in June 2011 to help develop and support the existing aerospace industry, including suppliers, in Renton and to attract new companies.

Abbott Nutrition invites second wave of research proposals on diet and cognition

Posted on August 4, 2012 by ev1

Abbott Nutrition and the University of Illinois Urbana-Champaign are inviting researchers to bid for cash to fund new diet and cognition-related projects that could help Abbott develop the next generation of brain foods and supplements.

Target groups for studies include full-term and premature infants, pre-adolescent children, healthy adults, elderly adults, cancer patients and traumatic brain injury patients

The Center for Nutrition, Learning, and Memory, a collaboration between the two partners, is seeking pre-proposals by Sept 7, 2012 in its second annual research challenge.

Last year, the center awarded nearly $10m in funding for interdisciplinary research projects involving nutrition, the brain and cognition.

This years funding will be announced by December 17, with the amount awarded based on the quality of proposals.

Cognition research is one of Abbott's top glocal priorities

Speaking to NutraIngredients-USA in May,an Abbott spokeswoman said: Cognition research is one of Abbotts top global priorities."

She added: The research collaboration is intended to help uncover relationships between nutrition and cognition, and carry those discoveries to innovative nutritional products across all of our categories including pediatric, adult and performance nutrition.

Nutrients of interest include the long chain omega-3 fatty acids EPA and DHA, Beta-hydroxy beta-methylbutyrate (HMB), flavonoids and lutein, while target groups include full-term and premature infants, pre-adolescent children, healthy adults, elderly adults, cancer patients and traumatic brain injury patients.

Barangay Aides Boost Nutrition Drive

Posted on August 4, 2012 by ev1

SAN JOSE, Antique (PIA) Barangay Nutrition Scholars (BNS) play a key role in the implementation of nutrition programs.

The BNS reach out to poor households in remote villages and upland areas to bring governments health and nutrition services, said Jemma M. Bacongallo, president of Provincial Association of Barangay Nutrition Scholars in Antique.

Crossing rivers, walking through slippery roads and steep slopes just to reach far-flung communities during Operation Timbang, Parents Nutrition Classes among other activities is a great challenge to us BNS, Bacongallo said.

She said the BNS are inspired most by the thought that we are not working just for our honorarium or reward, but we are on a mission to empower families to become more caring to their children by putting priority to their health, nutrition and education.

Antique has 642 BNS covering 590 barangays, 19 of which are in the island town of Caluya, 3 are in the island barangays of Culasi and most are in the upland areas of the province.

There are barangays especially with big populations that have two or more BNS but most have only one BNS with sitios (villages) located far from each other.

What made the Province of Antique more challenging is the fact that it ranked no. 1 in Region 6 in terms of malnutrition, said Bacongallo.

We have done our best, and remain committed to work hard, however, attending to the health and nutrition problems is no joke. We need more resources, health workers and most importantly cooperation of families, she added.

We are glad that the Department of the Interior and Local Government has issued a Memorandum Circular to all Punong Barangays not to replace us with their own appointees every time the new Punong Barangay is elected, if we are still active in performing our task, said Bacongallo.

As we pledged to do the best we can, she said, we appeal to the local officials to be kind and understanding to our needs, much more our safety while performing our duties.

NUS researchers identify a novel double-stranded DNA structure

Posted on August 4, 2012 by ev1

This novel double-stranded DNA structure produced through mechanical stretching has been successfully demonstrated by researchers from the National University of Singapore. Credit: National University of Singapore

By way of mechanical stretching, National University of Singapore researchers identify a novel double-stranded DNA structure, thus successfully resolving a 16-year-old scientific debate over the existence of a double-stranded DNA structure.

Double-stranded DNA has often been described as a right-handed helical structure, known as B-DNA. To perform its multiple functions, double-stranded DNA has multiple structures depending on conditions. For example, the melted DNA bubble forms during transcription elongation and the left-handed helical Z-DNA forms hypothetically during transcriptional regulations.

Scientists have been proposing a novel form of double-stranded DNA structure since 1996. Referred to as 'S-DNA', it is produced from stretching the B-form DNA beyond a certain 'transition force' of around 65 pN to approximately 1.7-fold in length (termed as DNA overstretching transition). Its existence has sparked a 16-year scientific debate since it was proposed, as many other evidences suggested that DNA overstretching transition was merely a force-induced DNA melting transition, leading to peeled-apart single-stranded DNA.

At National University of Singapore (NUS), the research was led by Associate Professor Jie Yan, from the Department of Physics, Faculty of Science and Mechanobiology Institute, Singapore. It succeeded in demonstrating the intricacies of the DNA mechanics in highly sensitive single-DNA stretching experiments.

Assoc Prof Yan and his team found that DNA overstretching may involve two transitions that are distinct in their transition kinetics, namely, a slower hysteretic peeling transition to peeled-apart single-stranded DNA and a faster non-hysteretic transition to an unknown DNA structure. However, whether the unknown DNA structure produced from the non-hysteretic transition is the S-DNA or two single-stranded DNA strands through inside-DNA-melting, remains a question.

Their findings were published in Nucleic Acids Research.

In another recent work published in Proceedings of the National Academy of Sciences, Assoc Prof Yan and co-researchers examined the thermodynamics associated with the two transitions. They found that the non-hysteretic transition was associated with a small negative entropy change, in contrast to the large positive entropy change found during the hysteretic peeling transition. This result strongly favors DNA re-arrangement into a highly ordered, non-melted state during the non-hyteretic transition. They also demonstrated that the selection between the two transitions was dependent on DNA base-pair stability and could be represented in a multi-dimensional phase diagram.

Their results not only brought clarity to the scientific debate of whether S-DNA exists, but also provided important insights to the possible structures and functions of the mysterious S-DNA.

Given its elongated structure, the S-DNA may be a potential binding substrate for DNA intercalators, including those used in chemotherapeutic treatment to inhibit DNA replication in rapidly growing cancer cells. In cells, many DNA-binding proteins utilize side chain intercalation to distort the DNA backbone. Therefore, the S-DNA may also be a potential binding substrate for these proteins that occur in living organisms.

Convicted cop’s DNA not on coat

Posted on August 4, 2012 by ev1

By Mike Wagner

The Columbus Dispatch Friday August 3, 2012 7:03 AM

On the day he was sentenced to life in prison for killing his ex-wife, Douglas Prade stood up in court, defiantly proclaimed his innocence and challenged the justice system to find the real killer.

God, Margo, myself and the person who killed Margo know that I am innocent, he said.

Now, 14 years later, lab-test results show that DNA recovered from the Summit County murder scene didnt come from Prade, a former Akron police captain convicted of killing Margo Prade, a prominent doctor and the mother of his two children.

Prade, 66 and serving a life sentence at the Madison Correctional Institution, was found guilty of shooting Margo six times after a struggle in her van in a parking lot outside of her office.

The DNA testing, conducted by DNA Diagnostics Center of Fairfield, north of Cincinnati, focused on the lab coat Margo Prade was wearing during the attack, and specifically a bite mark left on her arm by her killer.

Testing results found male DNA present within the bite mark, but it didnt match Douglas Prade. Further testing of the lab coat and other evidence conducted by the Ohio Bureau of Criminal Investigation also excluded Prades DNA.

The bite mark was pivotal in the prosecutions case against Prade. During his trial, an expert testified that the bite mark matched Prades teeth.

But Prade and his attorneys have argued that the bite mark testimony was based on junk science, and it misled the jury in a case that has received national attention.

DNA testing identifies NC woman missing since 1992

Posted on August 4, 2012 by ev1

RALEIGH, N.C. (AP) Modern DNA testing has helped law-enforcement identify the remains of a Johnston County woman who disappeared in Virginia nearly 20 years ago, officials said Friday.

Angie Faye Toler left North Carolina in 1992 to move to Richmond, Va., and live with a boyfriend. The boyfriend returned to Smithfield, but Toler was never seen again. Her body was found near railroad tracks in November of that year. With no identification and no relatives around, her case was listed as an unidentified deceased.

Nona Best, supervisor of the N.C. Center for Missing Persons, attended an academy of the National Missing and Unidentified Persons System, or NamUs, last November. During a presentation by the VA Medical Examiner's Office, she noticed a picture that looked familiar. Best approached the instructor after his presentation and asked to see the picture again.

"Once I saw the picture up close I knew it was her," Best said. "She looked just like herself and her sister."

When Best returned to her office in Raleigh, she contacted the family and Lara A. Frame, an investigator with the chief medical examiner's office in Virginia. DNA from Toler's mother and sister was sent to the University of North Carolina at Chapel Hill to compare with the unidentified body.

On Tuesday, Best was advised by Frame that the DNA was a positive match.

Best and Princeton Police Chief Tyrone Sutton informed Toler's sister, Cora Prince, and her mother, Deloris Sherod.

"The Lord answers prayers. I prayed I would find out what happen to her before I left this earth. I'm at peace now," Sherod said.

Current ratings for: DNA Clue Discovered For Why Women Outlive Men

4.5 (2 votes)

Researchers from Monash University in Australia and Lancaster University in the UK, write about their work in the 2 August online issue of Current Biology.

They found male fruit flies appear to have mutations in their mitochondrial DNA that affect how fast they age and how long they live.

Scientists use fruit flies as models for studies in genes and aging because their biological processes are remarkably similar to that of other animals, such as humans, and with a lifespan of about a month, it doesn't take too long to investigate generational effects.

Senior author Damian Dowling, a research fellow in the Monash School of Biological Sciences, told the press:

"All animals possess mitochondria, and the tendency for females to outlive males is common to many different species. Our results therefore suggest that the mitochondrial mutations we have uncovered will generally cause faster male aging across the animal kingdom."

"Intriguingly, these same mutations have no effects on patterns of aging in females. They only affect males," he added.

Mitochondria are special subunits of cells, about the same size as bacteria, that provide the energy for life. They combine sugar and oxygen into adenosine triphosphate or ATP, molecular packets of energy that are usable by cells.

3D movie at 'ultraresolution' shows how cell`s machinery bends membrane inwards

Posted on August 4, 2012 by ev1

Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have combined the power of two kinds of microscope to produce a 3-dimensional movie of how cells 'swallow' nutrients and other molecules by engulfing them. The study, published today in Cell, is the first to follow changes in the shape of the cell's membrane and track proteins thought to influence those changes. It also provides ample data to investigate this essential process further.

This 'swallowing', called endocytosis, is involved in a variety of crucial tasks. It is used by brain cells relaying information to each other, for instance, and is also hijacked by many viruses, which use it to invade their host's cells. When a cell is about to swallow some molecules, a dent appears in the cell's membrane, and gradually expands inwards, pinching off to form a little pouch, or vesicle, that transports molecules into the cell.

The data used to make the video is freely available to the scientific community and will, Kaksonen and Briggs believe, provide valuable information to others trying to develop physical models of how this process works. The EMBL scientists themselves are probing the roles of individual proteins in this process, by perturbing them, and would like to extend the current work in yeast to human cells.

Ways to Reduce Body Odor

Posted on August 4, 2012 by ev1

You know you're slightly pungent after a hard Spinning class or garlicky dinner. But it turns out that some less expected factorslike how quickly you get dressed in the morning, the amount of carbs you eat, or whether you snorecan also affect your BO, breath, gassiness, and more.

Here's how to fix it, fast.

1. You Don't Towel Off After Showering A speedy post-shower rubdown may end up causing a problem later on. That's because moisture can get trapped between folds of skin, like below your breasts, under your love handles, or even between your toes, says Dr. Marina Peredo, a board-certified dermatologist in private practice in Smithtown, N.Y. "There's no access to air there, and it's easier for bacteria and fungi to multiply and mix with sweat, causing odor and irritation," she says.

Fix it: Peredo recommends this trick to her patients: "After you dry off, set a blow-dryer to cool and wave it over your belly, groin, feetanywhere that gets uncomfortably sweaty." You can also sprinkle an absorbent powder with antifungal properties onto your skin or in your shoes.

10 Worst Germ Hot Spots

2. You Love Spicy Foods Foods with pungent ingredients, such as curry, garlic, and other spices, can not only cause bad breath, but also a bit of a body odor.

When digested, these foods produce several stinky sulfur-containing gases. Most of these byproducts are metabolized in the intestines and liver, but some, such as allyl methyl sulfide, are absorbed into the bloodstream and released through your lungs and pores, an effect that can last for a few hours or more, says Dr. Debra Jaliman, assistant professor of dermatology at Mt. Sinai School of Medicine.

Fix it: You can temporarily mask bad breath with mouthwash or by chewing a bit of fresh parsley, mint, or fennel seeds, but you'll have to wait until your body is done digesting before all the odor is completely gone. Sit down to a spicy meal in good company; it's tough to smell it on others if you all eat the same thing, says Richard Price, DMD, spokesperson for the American Dental Association. Avoid garlic-rich chow in the hours before an important meeting or date.

3. You BrushBut Only Your Teeth Neglect your tongue, and your breath may not be as fresh as you'd like. Your tongue is covered with thousands of small hairlike projections called papillae, which can trap and harbor tiny scraps of food. So even if you brush and floss regularly, small remains from your meals can hang behind, collecting bacteria and emitting hydrogen sulfide vaporsaka bad breath.

Fix it: Mouthwashes may help, but the best way to remove bacteria, dead cells, and food debris from the crevices of your tongue is with an inexpensive tongue scraper. Brushing your tongue with a soft-bristled toothbrush works well too. Gently clean as far back as you can without gagging. Also, switch to a toothpaste that contains chlorine dioxide or tea tree oil, a powerful disinfectant with a pleasant, eucalyptus-like smell.

Study finds coffee may calm Parkinson’s disease

Posted on August 4, 2012 by Fredricko

Drinking too much coffee can give the average Joe the jitters, but scientists say caffeine may have the opposite effect on people with Parkinson's disease.

The Canadian study found that drinking between two and four cups of coffee a day can help control tremors, opening the door to new treatment options for the progressive neurodegenerative condition that affects more than 10,000 Kiwis.

Symptoms can include tremors, stiffness of muscles, depression, disturbance of normal sleep, fatigue and lack of sense of smell.

Parkinson's New Zealand chief executive Deirdre O'Sullivan said she was excited by the research but expressed caution at the small scale of the study.

The effect of caffeine on the healthy human brain was widely known but she had not heard any research into its effects regarding Parkinson's, she said.

Coffee could also lead to negative effects, so she said it was probably not wise for those suffering from the disease to dramatically increase their intake until more research had been done.

The study was one of the first in humans to show that caffeine can help with movement impairment in people who had the disease, said study author Ronald Postuma, of McGill University in Montreal.

Previous studies have found that people who drink caffeine are less likely to develop Parkinson's.

Sixty-one sufferers - whose symptoms included daytime sleepiness and some motor symptoms - were given either a caffeine supplement or placebo pill.

Members of the caffeine group were given 100 milligrams of caffeine twice a day for three weeks, then 200 milligrams twice a day for three weeks, which is the equivalent of between two and four cups of coffee a day.
