Biosingularity

Researchers have built a computer model of the crowded interior of a bacterial cell that – in a test of its response to sugar in its environment – accurately simulates the behavior of living cells. The new “in silico cells” are the result of a collaboration between experimental scientists at the Max Planck Institute of [...]

Researchers at IBM are designing nanoparticles that kill bacteria by poking holes in them. The scientists hope that the microbes are less likely to develop resistance to this type of drug, which means it could be used to combat the emerging problem of antibiotic resistance. This type of drug has not had much success in [...]

Measuring an overweight child’s wrist size appears to be a better predictor of diabetes and heart risk than calculatingbody mass index, new research suggests. Wrist size was strongly correlated with insulin resistance inoverweight children in the study conducted by researchers at Italy’s Sapienza University of Rome. The findings suggest that the simple, low-tech practice of using a tape measure to [...]

Researchers at The University of Western Ontario have discovered a strategy for stimulating the formation of highly functional new blood vessels in tissues that are starved of oxygen. Dr. Geoffrey Pickering and Matthew Frontini at the Schulich School of Medicine & Dentistry developed a strategy in which a biological factor, called fibroblast growth factor 9 [...]

Researchers at the La Jolla Institute for Allergy & Immunology, have discovered a molecule’s previously unknown role as a major trigger for airway remodeling, which impairs lung function, making the molecule a promising therapeutic target for chronic asthma, chronic obstructive pulmonary disease (COPD) and several other lung conditions. A scientific paper on the finding was [...]

Eating fatty fish or other foods rich in healthy omega-3 fatty acids during pregnancy may help lower your risk of developing symptoms commonly seen in postpartum depression, a small study suggests. The findings are slated for presentation at the Experimental Biology 2011 meeting in Washington, D.C. Many new mothers experience the “baby blues” in the [...]

Scientists have moved a step closer to being able to develop a computer model of the brain after developing a technique to map both the connections and functions of nerve cells in the brain together for the first time. A new area of research is emerging in the neuroscience known as ‘connectomics’. With parallels to [...]

The benefits of blueberry consumption have been demonstrated in several nutrition studies, more specifically the cardio-protective benefits derived from their high polyphenol content. Blueberries have shown potential to have a positive effect on everything from aging to metabolic syndrome. Recently, a researcher from Texas Woman’s University (TWU) in Denton, TX, examined whether blueberries could play [...]

Scientists at Harvard University have harnessed the prowess of fast-replicating bacterial viruses, also known as phages, to accelerate the evolution of biomolecules in the laboratory. The work, reported this week in the journal Nature, could ultimately allow the tailoring of custom pharmaceuticals and research tools from lab-grown proteins, nucleic acids, and other such compounds. The researchers, led [...]

When viruses attack, one molecule more than any other fights back. Interferon triggers the activation of more than 350 genes, and despite the obvious connection, the vast majority have never been tested for antiviral properties. A team of researchers, led by scientists from Rockefeller University, for the first time has carried out a comprehensive, systematic [...]

n a first-of-its-kind study with nuts, randomized controlled-feeding research conducted by the Agricultural Research Service (ARS) of the United States Department of Agriculture (USDA) found that fat in pistachios may not be completely absorbed by the body. The findings indicate that pistachios may actually contain fewer calories per serving than originally thought – further validating [...]

Whitehead Institute researchers have discovered that a differentiated cell type found in breast tissue can spontaneously convert to a stem-cell-like state, the first time such behavior has been observed in mammalian cells. These results refute scientific dogma, which states that differentiation is a one-way path; once cells specialize, they cannot return to the flexible stem-cell [...]

Women under the age of 75 with high vitamin D status were less likely to have early age-related macular degeneration (AMD), the leading cause of irreversible vision loss in adults, a University at Buffalo study has shown. The disease affects approximately 9 percent of Americans aged 40 and older. The paper is published in the [...]

Tart cherries have a unique combination of powerful antioxidants that may help reduce risk factors for heart disease, according to new research presented at the Experimental Biology annual meeting in Washington, DC. In a series of three studies, researchers from University of Michigan, University of Arizona and Brunswick labs studied the antioxidant levels and anti-inflammatory [...]

The Allen Institute for Brain Science has released the world’s first anatomically and genomically comprehensive human brain map, a previously unthinkable feat made possible through leading-edge technology and more than four years of rigorous studies and documentation. The unprecedented mappings are the foundation for the Allen Human Brain Atlas, an online public resource developed to [...]

Everyone has heard the old adage, “an apple a day keeps the doctor away.” We all know we should eat more fruit. But why apples? Do they contain specific benefits? According to Dr. Bahram H. Arjmandi, PhD, RD, Margaret A. Sitton Professor and Chair, Department of Nutrition, Food and Exercise Sciences at The Florida State [...]

A team of scientists at Penn State University, the Salk Institute for Biological Studies, and other institutions have developed a method for recreating a schizophrenic patient’s own brain cells, which then can be studied safely and effectively in a Petri dish. The method brings researchers a step closer to understanding the biological underpinnings of schizophrenia. [...]

New research raises hopes that a so-called “artificial pancreas” can help patients with type 1 diabetes better control their disease. Adults with type 1 diabetes in a newly published study showed improvements in overnight blood sugar control when an experimental computer-assisted device was used, with fewer episodes of levels dropping to dangerously low levels. For [...]

It is well known that the human body has a highly developed immune system to detect and destroy invading pathogens and tumor cells. Now, researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the body has a second line of defense against cancer – healthy cells. A new [...]

A startup called T2 Biosystems is developing a test that uses magnetic nanoparticles to detect blood-borne infections in hours—compared to the days it now takes using conventional lab methods. The company’s first device—about the size of a printer—will target Candida, a fungus that is the third-most-common cause of hospital-acquired infections. The detection system can identify [...]

A natural hormone known to inhibit aging can also protect kidneys against renal fibrosis, UT Southwestern Medical Center researchers have demonstrated. Scientists led by Dr. Makoto Kuro-o, associate professor of pathology, showed in mice that the anti-aging hormone Klotho suppressed both renal fibrosis – a common complication of chronic kidney disease – and the spread [...]

The judgments we make about the intimacy of other couples’ relationships appear to be influenced by the brain chemical serotonin, reports a new study published in Biological Psychiatry. Healthy adult volunteers, whose levels of serotonin activity had been lowered, rated couples in photos as being less intimate and less romantic than volunteers with normal serotonin activity. [...]
