Biologists elucidate how muscle stem cells colonize special niches

Muscles have a pool of stem cells which provides a source for muscle growth and for regeneration of injured muscles. The stem cells must reside in special niches of the muscle for efficient growth and repair.

Researchers obtain first detailed and complete picture of PRC2 protein

The first detailed and complete picture of a protein complex that is tied to human birth defects as well as the progression of many forms of cancer has been obtained by an international team of researchers led by scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab).

Brandeis University biology professor receives NIH Director's New Innovator award

Chances are you didn't spend much time this morning getting your shoes on or thinking about which route you would take to work. But for people suffering with debilitating diseases such as ALS (Lou Gehrig's disease) or Alzheimer's, such simple functions -- and even activities like breathing and eating -- can be a struggle.

Novel method could help advance fight against persistent 'HIV latency'

Scientists at the Gladstone Institutes have gotten us one step closer to understanding and overcoming one of the least-understood mechanisms of HIV infection-by devising a method to precisely track the life cycle of individual cells infected with HIV, the virus that causes AIDS.

Stanford and MBL scientists win prestigious Lasker Awards

Scientists who invented new ways to study how "cargo" is moved within cells and, as a result, discovered a new biological motor protein, kinesin, at the Marine Biological Laboratory (MBL) in Woods Hole, Mass., have received the prestigious 2012 Lasker Award for Basic Medical Research, the Albert and Mary Lasker Foundation announced today.

Biopsies may misdiagnose eosinophilic esophagitis

University of Utah engineers mapped white blood cells called eonsinophils and showed an existing diagnostic method may overlook an elusive digestive disorder that causes swelling in the esophagus and painful swallowing.

New infrared spectroscopy technique to analyze pharmacological agent-protein interactions

RUB-Researchers from the Chair for Biophysics have developed a new method for the detailed study of the interaction between pharmaceuticals and their target proteins.

FSU researchers achieve significant benchmarks in alpha-tropomyosin study

Florida State University researchers led by physics doctoral student Campion Loong have achieved significant benchmarks in a study of the human cardiac protein alpha-tropomyosin, which is an essential, molecular-level component that controls the heart's contraction on every beat.

Acorda’s GGF2 can improve erectile function after cavernous nerve damage

Acorda Therapeutics, Inc. announced data from a preclinical study showed that treatment with Glial Growth Factor 2 (GGF2) improved erectile function in an animal model following a cavernous nerve (CN) injury, a common complication of prostate surgery.

SPR microscopy examines binding kinetics of membrane proteins

Proteins adorning the surfaces of human cells perform an array of essential functions, including cell signaling, communication and the transport of vital substances into and out of cells. They are critical targets for drug delivery and many proteins are now being identified as disease biomarkers - early warning beacons announcing the pre-symptomatic presence of cancers and other diseases.

Confocal light sheet microscopy yields high-resolution views of brain’s neural pathways

Shortly after the Hubble Space Telescope went into orbit in 1990 it was discovered that the craft had blurred vision. Fortunately, Space Shuttle astronauts were able to remedy the problem a few years later with supplemental optics. Now, a team of Italian researchers has performed a similar sight-correcting feat for a microscope imaging technique designed to explore a universe seemingly as vast as Hubble's but at the opposite end of the size spectrum—the neural pathways of the brain.

Study identifies how RNA viruses hijack a host cell to multiply

By discovering how certain viruses use their host cells to replicate, UC Irvine microbiologists have identified a new approach to the development of universal treatments for viral illnesses such as meningitis, encephalitis, hepatitis and possibly the common cold.

Alcohol can cause more than one pattern of birth defects

A collaborative research effort by scientists at the University of North Carolina School of Medicine, Duke University, and University College of London in the UK, sheds new light on alcohol-related birth defects.

Overtreatment of malaria in central, south Asia leading to neglect of other diseases, study finds

"Over diagnosis and mistreatment of malaria in central and south Asia may be widespread, leading to the neglect of other serious illnesses, according to a new study from Afghanistan," published in the British Medical Journal last month, SciDev.Net reports.

Scientists dissect how sperm cells of the fruit fly build their flagella

Sperm swim, lung cells sweep mucus away, and the cells in the female Fallopian tube move eggs from the ovary to the uterus. Underlying these phenomena are flagella - slender, hair-like structures extending from the surface of the cells, that bend, beat or wave rhythmically. In the latest issue of the journal Developmental Cell, scientists from the Instituto Gulbenkian de Ciência (IGC), in Portugal, have dissected how sperm cells of the fruit fly build their flagella.

New life for forgotten technique in detecting resistant tuberculosis

Scientists of the Antwerp Institute of Tropical Medicine have breathed new life into a forgotten technique and so succeeded in detecting resistant tuberculosis in circumstances where so far this was hardly feasible. Tuberculosis bacilli that have become resistant against our major antibiotics are a serious threat to world health.

New method gives precise picture of how immune system works

Chronic infections are a large and growing problem throughout the developed world, and intensive research is being conducted in ways to combat the recalcitrant bacteria. When bacteria aggregate into so-called biofilm, they become resistant to antibiotics. Until now scientists have only been able to speculate about what happens when bacteria overpower the immune system during a chronic infection.
