New biosensor could help doctors devise new ways to minimize brain damage during heart surgery

Johns Hopkins engineers and cardiology experts have teamed up to develop a fingernail-sized biosensor that could alert doctors when serious brain injury occurs during heart surgery. By doing so, the device could help doctors devise new ways to minimize brain damage or begin treatment more quickly.

Breast cancer drug appears to protect cells against UV radiation, inflammation

Exemestane, a synthetic steroid drug widely prescribed to fight breast cancers that thrive on estrogens, not only inhibits the production of the hormone, but also appears to protect cells throughout the body against damage induced by UV radiation, inflammation and other assaults, according to results of research by Johns Hopkins scientists.

New zebrafish technique finds potential treatments for multiple diseases

Skeletal muscle has proved to be very difficult to grow in patients with muscular dystrophy and other disorders that degrade and weaken muscle. Researchers at Boston Children's Hospital's Stem Cell Program now report boosting muscle mass and reversing disease in a mouse model of Duchenne muscular dystrophy, using a "cocktail" of three compounds identified through a new rapid culture system. Adding the same compounds to stem cells derived from patients' skin cells, they then successfully grew human muscle cells in a dish.

Study reveals that lower dose of BPA contributes to large range of health problems in humans

Bisphenol A (BPA) is a known endocrine disruptor that hijacks the normal responses of hormones. Yet, traditional toxicology studies indicate that only very high doses of this chemical affect exposed animals-doses as high as 50 mg/kg/day.

CHFA launches five-part guide to help Canadians make informed decisions about natural health

To celebrate Natural Health Products Week, the Canadian Health Food Association is launching a free, five-part guide aimed at helping Canadian families make informed decisions about natural health. The Canadian Family's Guide to Navigating Natural Health, was developed with nutritionist and author Lianne Phillipson-Webb.

Discovery may lead to curing of Alzheimer's and Parkinson's disease via photo therapy

Researchers at Chalmers University of Technology in Sweden, together with researchers at the Polish Wroclaw University of Technology, have made a discovery that may lead to the curing of diseases such as Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease (the so called mad cow disease) through photo therapy.

Researchers receive grant to develop new device that identifies healthy sperm cells for IVF

The World Health Organization estimates more than 70 million couples worldwide are unable to conceive each year, with close to a third of those cases attributable solely to issues with male fertility-including low sperm count and low sperm motility (a limited ability to swim).

Common birth defect in male infants weakly linked to commercial pesticides

A study of several hundred chemicals used in commercial pesticides has found only weak evidence that any of them are associated with a common birth defect in male infants.

Biocompatible compounds can be used to develop customized implant designs with 3-D printing

Researchers from North Carolina State University, the University of North Carolina at Chapel Hill and Laser Zentrum Hannover have discovered that a naturally-occurring compound can be incorporated into three-dimensional (3-D) printing processes to create medical implants out of non-toxic polymers.

Study could enhance process of reprogramming adult cells into embryonic-like stem cells

Bioengineers at the University of California, Berkeley, have shown that physical cues can replace certain chemicals when nudging mature cells back to a pluripotent stage, capable of becoming any cell type in the body.

Carcinogens detected in emissions downwind of 'Industrial Heartland'

Levels of contaminants higher than in some of the world's most polluted cities have been found downwind of Canada's largest oil, gas and tar sands processing zone, in a rural area where men suffer elevated rates of cancers linked to such chemicals.

CSHL researchers explore how the brain integrates multiple signals to identify one unique smell

Think of the smell of an orange, a lemon, and a grapefruit. Each has strong acidic notes mixed with sweetness. And yet each fresh, bright scent is distinguishable from its relatives. These fruits smell similar because they share many chemical compounds. How, then does the brain tell them apart? How does the brain remember a complex and often overlapping chemical signature as a particular scent?

WHO calls on countries to eliminate lead poisoning that affects children globally

Lead poisoning has devastating health consequences, in particular for children, with childhood lead exposure estimated to contribute to 600 000 new cases of children with intellectual disabilities every year. Overall, 99% of children affected by high exposure to lead live in low- and middle-income countries, says WHO on the occasion of International Lead Poisoning Prevention Week of Action, and calls on countries to strengthen national actions to eliminate lead paint.
