Quarraisha Abdool Karim wins TWAS-Lenovo Prize
South African scientist named winner of The World Academy of Sciences' most prestigious award for commitment to life-saving research that protects African women from HIV/AIDS

Georgia State astronomers image the exploding fireball stage of a nova
Astronomers at Georgia State University's Center for High Angular Resolution Astronomy have observed the expanding thermonuclear fireball from a nova that erupted last year in the constellation Delphinus with unprecedented clarity.

Turning loss to gain: Cutting power could dramatically boost laser output
Re-examining longstanding beliefs about the physics of lasers, engineers have shown that carefully restricting the delivery of power to certain areas within a laser could boost its output by many orders of magnitude.

Heart drug may help treat ALS, mouse study shows
Digoxin, a medication used in the treatment of heart failure, may be adaptable for the treatment of amyotrophic lateral sclerosis, a progressive, paralyzing disease, suggests new research at Washington University School of Medicine in St.

New evidence for an exotic, predicted superconducting state
A research team led by a Brown University physicist has produced new evidence for an exotic superconducting state, first predicted a half-century ago, that can arise when a superconductor is exposed to a strong magnetic field.

Unsuspected gene found frequently mutated in colorectal, endometrial cancers
Scientists say they have identified in about 20 percent of colorectal and endometrial cancers a genetic mutation that had been overlooked in recent large, comprehensive gene searches.

Plymouth University receives £1M to develop innovative dementia diagnostic technique
A research team from Plymouth University, together with colleagues from Swansea University, has received funding of £1M from the Engineering and Physical Sciences Research Council to develop an innovative, real-time diagnostic technique for dementia using wonder-material graphene.

A key to aortic valve disease prevention: Lowering cholesterol early
An international research team led by the Research Institute of the McGill University Health Centre (RI-MUHC) and Lund University has provided new evidence that aortic valve disease may be preventable.

Dietary flavanols reverse age-related memory decline
Dietary cocoa flavanols -- naturally occurring bioactives found in cocoa -- reversed age-related memory decline in healthy older adults, according to a study led by Columbia University Medical Center scientists.

Real-time readout of neurochemical activity
Scientists have created cells with fluorescent dyes that change color in response to specific neurochemicals.

A switch to dampen malignancy
Ludwig Oxford researchers have discovered a key mechanism that governs how cells of the epithelia, the soft lining of inner body cavities, shift between a rigid, highly structured and immobile state and a flexible and motile form.

Genetic predisposition to elevated LDL-C associated with narrowing of the aortic valve
In an analysis that included approximately 35,000 participants, genetic predisposition to elevated low-density lipoprotein cholesterol was associated with aortic valve calcium and narrowing of the aortic valve, findings that support a causal association between low-density lipoprotein cholesterol and aortic valve disease, according to a study appearing in JAMA.

Right place, right time: Cellular transportation compartments
Proteins are the machinery that accomplishes almost every task in every cell in every living organism.

Breakthrough in molecular electronics paves the way for DNA-based computer circuits in the future
An international group of scientists reports reproducible and quantitative measurements of electricity flow through long molecules made of four DNA strands.

Activity in dendrites is critical in memory formation
Northwestern University researchers have discovered how neurons in the brain might allow some experiences to be remembered while others are forgotten.

International research group publishes updated criteria for diagnosing multiple myeloma
The International Myeloma Working Group today announced that it has updated the criteria for diagnosing multiple myeloma.

Team discovers how microbes build a powerful antibiotic
Researchers report in the journal Nature that they have made a breakthrough in understanding how a powerful antibiotic agent is made in nature.

New nanodevice to improve cancer treatment monitoring
In less than a minute, a miniature device developed at the University of Montreal can measure a patient's blood for methotrexate, a commonly used but potentially toxic cancer drug.
