As concerns about bacterial resistance to antibiotics grow, researchers are racing to find new kinds of drugs to replace ones that are no longer effective. One promising new class of molecules called acyldepsipeptides — ADEPs — kills bacteria in a way that no marketed antibacterial drug does — by altering the pathway through which cells rid themselves of harmful proteins.
When the UW’s medical school gave Tim Cordes a chance, he exceeded expectations, teaching others that being blind needn’t destroy one’s dreams.
We demonstrate a Google Glass-based rapid diagnostic test (RDT) reader platform capable of qualitative and quantitative measurements of various lateral flow immunochromatographic assays and similar biomedical diagnostics tests.

Inspired by natural materials like bone — a matrix of minerals and other substances, including living cells — MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving materials, such as gold nanoparticles and quantum dots.
"A new model predicts which influenza strain will be most prevalent next year, but glosses over reams of research to do so. If it can help us design more effective vaccines, does it matter? Find out..."
“More than 90 percent of professional science master’s graduates that we surveyed for 2013 were employed in a job related to their field of study,” she said, “and 68 percent of those employed in full-time jobs said they were earning above $50,000.” The blended degree, she explained, “grew out of the realization that we needed to prepare students not with the degree their professors have, but with degrees that are needed in the workplace.”
Watch the progression of PCR from its conception to advancements that are breaking ground into new and exciting applications.
"Purdue Univ. researchers have identified an important enzyme pathway that helps prevent new cells from receiving too many or too few chromosomes, a condition that has been directly linked to cancer and other diseases."
"A University of St Andrews study has found that — despite fears of a biodiversity crisis — there has, in fact, not been a consistent drop in numbers of species found locally around the world."
A survey of emergency contraceptive pills in Peru found that 28 percent of the batches studied were either of substandard quality or falsified. Many pills released the active ingredient too slowly. Others had the wrong active ingredient. One batch had no active ingredient at all.
Scientists have been given permission to grow genetically modified plants that could help protect against heart disease.
The extra chromosome behind Down’s syndrome can impact transcriptional regulation beyond chromosome 21, a study finds.

Check out this fascinating TED Talk! "Hugh Herr is building the next generation of bionic limbs, robotic prosthetics inspired by nature's own designs. Herr lost both legs in a climbing accident 30 years ago; now, as the head of the MIT Media Lab's Biomechatronics group, he shows his incredible technology in a talk that's both technical and deeply personal."
University of Texas at San Antonio microbiologist Karl Klose discusses the problem of antibiotic resistance in a 2013 TEDx talk.
"People may soon be able to learn whether or not they have lung cancer -- and how bad their cancer is -- by breathing into a tube."
"In recent years, the bacterial communities living in and on our bodies have captivated scientists and the public alike. The gut microbiome has been tied to diverse functions and linked to both health and disease. But researchers now know that the gastrointestinal tract is just one of the many microbial homes on the human body. Here, The Scientist looks at some of these bacterial communities outside the gut, including the vagina, the penis, the breast, the nose, and more."
"Most schools across the United States provide simple vision tests to their students—not to prescribe glasses, but to identify potential problems and recommend a trip to the optometrist. Researchers are now on the cusp of providing the same kind of service for autism."

"High-tech gloves can help people learn how to read and write Braille. The twist is that people wearing the glove don't have to pay attention. They learn while doing something else."
"A clinical trial involving nearly 300 Chinese men and women residing in one of China's most polluted regions found that daily consumption of a half cup of broccoli sprout beverage produced rapid, significant and sustained higher levels of excretion of benzene, a known human carcinogen, and acrolein, a lung irritant."
"Along with vaccination, antiviral drugs could play a key role in the eradication of poliovirus, but it’s unclear whether today’s candidate therapies will withstand the challenges of the clinic."
"Researchers from Northwestern Univ. and the Univ. of New Mexico have reported evidence for potentially oceans-worth of water deep beneath the U.S. Though not in the familiar liquid form — the ingredients for water are bound up in rock deep in the Earth's mantle — the discovery may represent the planet's largest water reservoir."
"In a paper published today by the journal Cell, Vanderbilt Univ. researchers establish for the first time that bromine, among the 92 naturally occurring chemical elements in the universe, is the 28th element essential for tissue development in all animals, from primitive sea creatures to humans."
