Study demonstrates BTG2 gene is crucial for neurogenesis and contextual memory function

The birth of new neurons, a process called neurogenesis, is continuously occurring in the brain, not only during development but also during adulthood within two specialized areas, the hippocampus and the subventricular zone.

Showing scan images to motivate healthy behaviors in patients provides mixed results

Can showing patients ultrasounds and X-rays of their bodies to point out existing health damage make patients change their risky behavior?

Study lays groundwork to develop new treatments for cardiovascular disease and other conditions

In a significant step toward restoring healthy blood circulation to treat a variety of diseases, a team of scientists at Weill Cornell Medical College has developed a new technique and described a novel mechanism for turning human embryonic and pluripotent stem cells into plentiful, functional endothelial cells, which are critical to the formation of blood vessels.

COTI's novel small molecule effective against pancreatic cancer in animal model

Critical Outcome Technologies Inc. announced more positive results today from animal experiments carried out at a prominent Canadian cancer research facility. This new series of experiments adds to the impressive data package for COTI-2, demonstrating efficacy both as a single agent and in combination with current first line therapies, as well as low toxicity in several different animal models of human cancers.

Older adults may be wiser decision-makers compared to younger counterparts

A new study has found promising evidence that the older brain's weakened ability to filter out irrelevant information may actually give aging adults a memory advantage over their younger counterparts.

New effort to produce standardized DNA parts for reducing development time of synthetic biology in labs

With seed money from the National Science Foundation (NSF), bioengineers from the University of California, Berkeley, and Stanford University are ramping up efforts to characterize the thousands of control elements critical to the engineering of microbes so that eventually, researchers can mix and match these "DNA parts" in synthetic organisms to produce new drugs, fuels or chemicals.

Researchers explain how HSV dismantles host's defense systems

A viral infection is like an uninvited, tenacious houseguest in the cell, using a range of tricks to prevent its eviction. Researchers at the Salk Institute for Biological Studies have identified one of the key proteins allowing herpes simplex virus (HSV) DNA to fly under the radar of their hosts' involuntary hospitality.

ChromoCure's aneuploidy theory of cancer further validated

ChromoCure, Inc. -- The Company announces that its long-held theory of cancer, aneuploidy, has been further validated by a study published in the January 15, 2010 issue of Cancer Research (Volume 70, Issue 2).

Mouse sperm can discriminate between its brethren and competing sperm, says study

Some mouse sperm can discriminate between its brethren and competing sperm from other males, clustering with its closest relatives to swim faster in the race to the egg. But this sort of cooperation appears to be present only in certain promiscuous species, where it affords an individual's sperm a competitive advantage over that of other males.

Quorum sensing offers a dynamic approach to increase sensitivity to external signals

Researchers at UC San Diego who last year genetically engineered bacteria to keep track of time by turning on and off fluorescent proteins within their cells have taken another step toward the construction of a programmable genetic sensor. The scientists recently synchronized these bacterial "genetic clocks" to blink in unison and engineered the bacterial genes to alter their blinking rates when environmental conditions change.

New research reveals grid cells in human brain provide a cognitive, spatial map

'Grid cells' that act like a spatial map in the brain have been identified for the first time in humans, according to new research by UCL scientists which may help to explain how we create internal maps of new environments.

Study indicates size of brain structures may predict performance and learning rates

Researchers can predict your performance on a video game simply by measuring the volume of specific structures in your brain, a multi-institutional team reports this week.

Study: PrEP treatment offers protection against HIV transmission in humanized mice

Systemic pre-exposure administration of antiretroviral drugs provides protection against intravenous and rectal transmission of HIV in mice with human immune systems, according to a new study published January 21, 2010 in the online journal PLoS ONE.

Discovery of new class of compounds may help fight hepatitis C

Stanford University School of Medicine scientists have discovered a novel class of compounds that, in experiments in vitro, inhibit replication of the virus responsible for hepatitis C. If these compounds prove effective in infected humans as well, they may dramatically accelerate efforts to confront this virus’s propensity to rapidly acquire drug resistance, while possibly skirting some of the troubling side effects common among therapies in current use and in late-stage development.

Life sciences and healthcare segments support nanotech venture capital investments

The heyday for nanotech venture capital (VC) likely saw its peak in 2008, when overall investment reached $1.4 billion. Last year, the sector raised only $792 million, signifying a 42% decline from 2008. But while overall nano VC backing is down, it's not out, according to a new report from Lux Research.

New class of HCV inhibitors discovered by Eiger BioPharmaceuticals

Eiger BioPharmaceuticals, Inc., a biotechnology company developing antiviral therapies, announced today the publication of research from the labs of Stanford scientist and Eiger Founder, Dr. Jeffrey Glenn, M.D., Ph.D. and colleagues entitled, "Identification of a Novel Class of HCV Inhibitors". Published in the January 20th edition of Science and Translational Medicine, the research validates a domain, termed 4BAH2, within the non-structural protein (NS4B) of the HCV genome, as essential for HCV replication and describes the development of a high-throughput screen leading to the identification of small molecule inhibitors of 4BAH2.

Study identifies new mechanism that causes allergic response in people

WHAT: A new study in human cells has singled out a molecule that specifically directs immune cells to develop the capability to produce an allergic response. The signaling molecule, called thymic stromal lymphopoietin (TSLP), is key to the development of allergic diseases such as asthma, atopic dermatitis (eczema) and food allergy.

Study shows nutrition has a direct influence on the immune system

Bonn researchers have discovered an elementary mechanism which regulates vital immune functions in healthy people. In situations of hunger which mean stress for the body's cells, the body releases more antimicrobial peptides in order to protect itself. The scientists will publish their results in the journal Nature.

Blueberries may help boost memory in older adults

Scientists are reporting the first evidence from human research that blueberries - one of the richest sources of healthful antioxidants and other so-called phytochemicals - improve memory.

Research shows brain abnormalities develop years before Parkinson's symptoms appear

Scientists who have identified brain networks damaged in Parkinson's disease have new evidence that these systems become abnormal a few years before symptoms appear. And what's more, parts of the network appear to respond in a last ditch attempt to rescue the brain.
