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.
Imagine being able to erase the innermost prejudices you are most ashamed of by simply turning...
Lysozyme, a naturally occurring antimicrobial enzyme, is used in food and beverage applications...
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.
An outbreak of STDs over several years has been driven by social media hookup sites and risky sex, according to the Rhode Island Department of Health. The state announced that it was combating an “epidemic of STDs”– and released some startling statistics.
ICYMI: Rise and Fall of NIH, Pompeii Restoration Like a Time Machine, Debate Over Nonacademic SkillsMay 29, 2015 9:07 am | by Michelle Taylor, Editor-in-Chief | News | Comments
Welcome to Laboratory Equipment's new Friday series, In Case You Missed It (ICYMI), where we bring you three trending news stories from the week.Questions about the NIH, amazing photos from Pompeii and the debate over nonacademic skills are on the menu this week.
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.
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.
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.
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.
The genetic roots of autism have been investigated for more than a decade, as DNA sequencing has continued to improve. A new study points to a particular mutation in mice causing autistic-like behavior, adding to a list of potential causes.
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.
The Dionne Quintuplets, born May 28, 1934, were the first set of quintuplets to survive infancy. They were identical as they all came from one single egg and were born outside of Callander, Ontario, Canada. All five survived into adulthood.
Laboratory Equipment’s scientist of the week is Keith Clay, a professor from IU Bloomington. He and a team found that ticks are moving around the country and the diseases they carry are spreading with them.
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.
We may cave in to peer pressure, marketing and persuasion, but faced with decisions, the default response programmed into our brains is to say "no," a recent study suggests.
A skull shows two wounds, almost identical, over the left brow, inflicted with the same implement, more than deep enough to kill. It is evidence of the oldest murder yet found on record, said scientists.
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.
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.
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.
A new ancestor has been added to our family tree. Australopithecus deyiremeda lived some time around 3.3 to 3.5 million years ago– at the same time that the famous “Lucy” species, Australopithecus afarensis, lived in the area.
People for the Ethical Treatment of Animals and the Physicians Committee for Responsible Medicine are asking for better tracking, and a gentler approach, for animal testing in the U.S.
Tests for antibiotic resistance can take up to three days to come back from the lab, hindering doctors’ ability to treat bacterial infections quickly. Now, researchers have designed a small and simple chip to test for antibiotic resistance in just one hour, giving doctors a shot at picking the most effective antibiotic to treat potentially deadly infections.
Rachel Carson, the author of Silent Spring, was born in Springdale, Pennsylvania, on May 27, 1907. Silent Spring, first published in September of 1962 and still in print today, is widely credited with aiding the launch of the environmental movement. It presented environmental problems to the general public more widely than any book before.
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. Researchers have calculated that a 5-decibel reduction in excess noise could lower the prevalence of hypertension by 1.4 percent and coronary heart disease by 1.8 percent, or 1.2 million and 279,000 people, respectively.
Researchers have developed a method to detect rare DNA mutations with an approach hundreds of times more powerful than current methods. The technique allows the researchers to find a figurative needle in a haystack that’s smaller than any needle.
Scientists around the world are using the programmability of DNA to assemble complex nanometer-scale structures. 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.
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.
