A team led by William Fenical at Scripps Institution of Oceanography at UC San Diego has discovered a new chemical compound from an ocean microbe in a preliminary research finding that could one day set the stage for new treatments for anthrax and other ailments such as methicillin-resistant...
New evidence from research suggests that infants fed formula, rather than breast milk, experience metabolic stress that could play a part in the long-recognized link between formula-feeding and an increased risk of obesity, type 2 diabetes and other conditions in adult life. The study appears in...
Humans and most mammals can determine the spatial origin of sounds with remarkable acuity. We use this ability all the time - crossing the street; locating an invisible ringing cell phone in a cluttered bedroom. To accomplish this small daily miracle, the brain has developed a circuit that's...
Researchers at USC have found that a class of pharmaceuticals can both prevent and treat Alzheimer's Disease in mice. The drugs, known as "TSPO ligands," are currently used for certain types of neuroimaging. "We looked at the effects of TSPO ligand in young adult mice when pathology was at an...
Two new minute spider species have been discovered from the Sichuan and Chongqing, China. The tiny new spiders are both less than 2 mm in length, with*Trogloneta yuensis*being as little as 1.01 mm and Mysmena wawuensis measured to be the even tinier 0.75 mm, which classes it among the smallest...
In many neurodegenerative diseases the neurons of the brain are over-stimulated and this leads to their destruction. After many failed attempts and much scepticism this process was finally shown last year to be a possible basis for treatment in some patients with stroke. But very few targets for...
The new feature of the antidepressant drugs of the 1990s was that they had milder side-effects than their predecessors. Combined with aggressive marketing, this meant that annual sales in Sweden increased from just under EUR 18 million to over EUR 100 million in the space of just a few years...
Dana-Farber Cancer Institute scientists and colleagues have discovered that pancreatic cancer cells' growth and spread are fueled by an unusual metabolic pathway that someday might be blocked with targeted drugs to control the deadly cancer. Cancer cells are known to "rewire" their metabolic...
Patients with diseases such as diabetes suffer from painful wounds that take a long time to heal making them more susceptible to infections that could even lead to amputations. A*STAR's discovery paves the way for therapeutics to improve healing of such chronic wounds, which are a significant...
Research conducted by Dr. Jayne S. Weiss, Professor and Chair of Ophthalmology at LSU Health Sciences Center New Orleans, and colleagues has discovered a new mutation in a gene that causes Schnyder corneal dystrophy (SCD.) The gene was found to be involved in vitamin K metabolism suggesting the...
It takes a lot to make a memory. New proteins have to be synthesized, neuron structures altered. While some of these memory-building mechanisms are known, many are not. Some recent studies have indicated that a unique group of molecules called microRNAs, known to control production of proteins...
In a genome-wide analysis of 13 metastatic prostate cancers, scientists at the Johns Hopkins Kimmel Cancer Center found consistent epigenetic "signatures" across all metastatic tumors in each patient. The discovery of the stable, epigenetic "marks" that sit on the nuclear DNA of cancer cells and...
Vitamin D slows the progression of cells from premalignant to malignant states, keeping their proliferation in check A team of researchers at McGill University have discovered a molecular basis for the potential cancer preventive effects of vitamin D. The team, led by McGill professors John...
Researchers at the University of Iowa have discovered a new cause of hydrocephalus, a devastating neurological disorder that affects between one and three of every 1,000 babies born. Working in mice, the researchers identified a cell signaling defect, which disrupts immature brain cells involved...
Two years ago, a 71-year-old Indiana man impaled his hand on a branch after cutting down a dead crab apple tree, causing an infection that led University of Utah scientists to discover a new bacterium and solve a mystery about how bacteria came to live inside insects...

While it is well known that starfish, zebrafish and salamanders can re-grow damaged limbs, scientists understand very little about the regenerative capabilities of mammals. Now, researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine report on the regenerative...
Scientists at the Montreal Neurological Institute and Hospital - The Neuro, McGill University working with a team at Oxford University have uncovered the genetic defect underlying a group of rare genetic disorders. Using a new technique that has revolutionized genetic studies, the teams...
