Researchers from the University of Washington, Rosalind Franklin University of Medicine and Science, Merck Laboratories, and Mount Sinai School of Medicine have released a study suggesting that specific laboratory and clinical tests can predict outcome of antibiotic therapy for infections in persons with diabetes.

Daniel O’Connor, M.D., Professor of Medicine and Pharmacology at the University of California, San Diego (UCSD) School of Medicine has studied about 265 twin pairs over the past few years, which has led him to some surprising discoveries.

"By studying many traits and genes, we have started to put together unexpected stories," he said.

Surgery is about to change with the introduction of a new surgical robotic system at the University of Calgary/Calgary Health Region. NeuroArm aims to revolutionize neurosurgery and other branches of operative medicine by liberating them from the constraints of the human hand.

For the past three years a satellite has circled the Earth, collecting data to determine whether two predictions of Albert Einstein's general theory of relativity are correct.

Climate change could trigger "boom and bust" population cycles that make animal species more vulnerable to extinction, according to Christopher C. Wilmers, an assistant professor of environmental studies at the University of California, Santa Cruz.

If your meat needs to be plumped up, try some collagen injections.

Injecting meatballs with collagen can help the meat to retain the important nutrients iodine and thiamine, a new study by researchers from the Agricultural University of Poznan in Poland shows.

Ancient aquatic amphibians developed the ability to feed on land before completing the transition to terrestrial life, researchers from Harvard University report this week in the Proceedings of the National Academy of Sciences.

A study by U.S. and Australian researchers is helping dispel the 40-year-old "thrifty genotype theory," which purports that certain minority groups are genetically prone to diabetes.

Grandparents of adopted grandchildren relate to them as an integral part of the family – just as they relate to their biological grandchildren. This was revealed in research conducted at the University of Haifa School of Social Work. This research is unique in the field in that it evaluated adoptive relationships from the viewpoint of grandparents; previous research examined relationships from the viewpoint of parents and children.

Results of two studies funded by Project A.L.S. and appearing in today's advance online publication of Nature Neuroscience demonstrate that embryonic stem cells may provide a new tool for studying disease mechanisms and for identifying drugs to slow ALS, also known as Lou Gehrig's disease.

Both studies were completed by researchers participating in an ongoing collaboration with the Project A.L.S./Jenifer Estess Laboratory for Stem Cell Research, the world's first and only privately funded laboratory focused exclusively on stem cells and ALS.

Two papers by Columbia and Harvard researchers report for the first time that astrocytes (the most abundant non-neuronal cells in the central nervous system), which carry a mutated gene known to cause some cases of amyotrophic lateral sclerosis (ALS/Lou Gehrig's disease), induce motor neuron death. This indicates that astrocytes may contribute to ALS by releasing a toxic factor that damages neurons.

Four-year-old girls are six times more likely to have a Body Mass Index (BMI) of more than 30 than they were 20 years ago and ten-year-olds are five times more likely, according to research published in the April issue of Acta Paediactrica.

We all know that eating fruits, vegetables and soy products provides essential nutrition for a healthy lifestyle, while obesity leads to the opposite. Yet proving the effect of nutrition, or obesity, on cancer is an experimental challenge and a focus for scientists. According to emerging evidence, eating well might still be one of the more pleasurable ways to prevent cancer and promote good health.

Abstract 4217: A novel mechanism for the chemoprotection by 3,3-diindolylmethane (DIM) and genistein for breast and ovarian cancer.

In the May 1st issue of Genes & Development, Drs. Yong Sun Lee and Anindya Dutta (UVA) reveal that microRNAs can function as tumor suppressors in vitro.

Using what is thought to be the world’s smallest pipette, two researchers at the U.S. Department of Energy’s Brookhaven National Laboratory have shown that tiny droplets of liquid metal freeze much differently than their larger counterparts. This study, focused on droplets just a billionth of a trillionth of a liter in size, is published in the April 15, 2007, online edition of Nature Materials.
