Fluid in Human Eye Contains 386 Previously Unknown Proteins

May 29, 2015 3:00 pm | by Mary Ann Liebert, Inc., publishers | News | Comments

Researchers conducting a comprehensive proteomics analysis of human aqueous humor samples identified 763 proteins— including 386 proteins detected for the first time— in this clear fluid that helps maintain pressure in the eye and nourishes the cornea and the lens. These proteins could have a role in disease processes affecting the eye and serve as valuable biomarkers for the development of diagnostics and drug candidates.

Neuroscientists Find Seat of Anxious Decisions in the Brain

May 29, 2015 3:00 pm | by MIT, Anne Trafton | News | Comments

Some decisions arouse far more anxiety than others. Researchers have now identified a neural circuit that appears to underlie decision-making in this type of situation, which is known as approach-avoidance conflict. The find could help researchers to discover new ways to treat psychiatric disorders that feature impaired decision-making, such as depression, schizophrenia and borderline personality disorder.

EPA Issues Rules to Protect Water

May 29, 2015 7:00 am | by Associated Press, Mary Jalonick | News | Comments

Drinking water for 117 million Americans will be protected under new rules shielding small streams, tributaries and wetlands from pollution and development, the Obama administration has said. The White House said the rules, issued by the EPA and U.S. Army Corps of Engineers, would provide much-needed clarity for landowners, but some Republicans and farm groups said they go much too far.

Dinosaurs were Warm-blooded, Study Says

May 29, 2015 7:00 am | by Seth Augenstein, Digital Reporter | News | Comments

Since their bones were first discovered in the 19th century, dinosaurs were thought to be simply giant dead lizards. Even the name translates to “terrible lizard” in Greek. But they may have much more in common with modern-day birds than was originally thought. A new study released today posits that the dinosaurs were warm-blooded – and not simply large cold-blooded reptiles.

Pentagon Accidentally Ships Live Anthrax Samples to 9 States

May 28, 2015 3:26 pm | by Michelle Taylor, Editor-in-Chief | Blogs | Comments

The Pentagon confirmed yesterday that it accidently shipped live anthrax samples from one of its labs in Utah to commercial labs in nine U.S states, as well as a U.S. military base in South Korea. But don’t worry, the CDC is on the case. The same CDC that accidently exposed 75 lab workers to a dangerous anthrax bacteria last summer—less than one year ago.

Subdermal Chip Offers Precise Medicine

May 28, 2015 3:00 pm | by EPFL | News | Comments

It’s only a centimeter long, it’s placed under your skin, it’s powered by a patch on the surface of your skin and it communicates with your mobile phone. Anew biosensor chip is capable of simultaneously monitoring the concentration of a number of molecules— such as glucose and cholesterol— and certain drugs.

Sleeping Cancer Can ‘Wake Up’ Years Later

May 28, 2015 9:58 am | by Seth Augenstein, Digital Reporter | News | Comments

Years, even decades, after remission some cancers return without warning. The “sleeping” cancer cells reactivate, “waking up” decades later, according to a British team of scientists, who say they may have found the molecular key to the change.

e-Stent Provides Feedback, Therapy Before Dissolving

May 28, 2015 7:00 am | by ACS | News | Comments

Every year, an estimated half-million Americans undergo surgery to have a stent prop open a coronary artery narrowed by plaque. But sometimes the mesh tubes get clogged. A multi-tasking stent could minimize the risks associated with the procedure. It can sense blood flow and temperature, store and transmit the information for analysis and can be absorbed by the body after it finishes its job.

Genetic Testing is Flawed

May 28, 2015 7:00 am | by Associated Press, Marilynn Marchione | News | Comments

The first report from a public-private project to improve genetic testing shows it is not as rock solid as many people believe, with flaws that result in some people wrongly advised to worry about a disease risk and others wrongly told to relax. Researchers say the study shows the need for consumers to be careful about choosing where to have a gene test done and acting on the results, such as having or forgoing a preventive surgery.

Perfume Researchers Seek Less Odorous Latrines

May 27, 2015 3:00 pm | by ACS | News | Comments

About 2.5 billion people worldwide don't have access to sanitary toilets. Latrines are an option for many of those people, but these facilities' overwhelming odors can deter users, who then defecate outdoors instead. To improve this situation, fragrance scientists paired experts' noses and analytical instruments to determine the odor profiles of latrines with the aim of countering the offensive stench.

DNA May Get Some New Letters

May 27, 2015 3:00 pm | by ACS | News | Comments

The DNA encoding all life on Earth is made of four building blocks called nucleotides, commonly known as "letters," that line up in pairs and twist into a double helix. Now, two groups of scientists are reporting for the first time that two new nucleotides can do the same thing— raising the possibility that entirely new proteins could be created for medical uses.

Piping Down Could Mean Nationwide Savings

May 27, 2015 7:00 am | by Univ. of Michigan School of Public Health | News | Comments

Reducing noise pollution in the U.S. wouldn't just impact hearing but could save $3.9 billion in health care spending by lowering the prevalence of health issues associated with excess noise.

Until now, however, production of these artificial structures has been limited to water-based environments, because DNA naturally functions inside the watery environment of living cells.

Bizarrely Hardy Virus Informs Gene Therapy Delivery

May 26, 2015 3:00 pm | by Univ. of Virginia Health System | News | Comments

By unlocking the secrets of a bizarre virus that survives in nearly boiling acid, scientists have found a blueprint for battling human disease using DNA clad in near-indestructible armor. Studying the virus, they discovered what appears to be a basic mechanism of resistance— to heat, to desiccation, to ultraviolet radiation. The find may help develop ways to package DNA for gene therapy.
