Better batteries from waste sulfur
A new chemical process can transform waste sulfur into a lightweight plastic that may improve batteries for electric cars, reports a University of Arizona-led team.

The tulip tree reveals mitochondrial genome of ancestral flowering plant
The extraordinary level of conservation of the tulip tree (Liriodendron tulipifera) mitochondrial genome has redefined our interpretation of evolution of the angiosperms (flowering plants), finds research in biomed Central's open access journal BMC Biology.

Genetic discovery found to influence obesity in people of African ancestry
The largest genetic search for

Mass. General team develops implantable, bioengineered rat kidney
Bioengineered rat kidneys developed by Massachusetts General Hospital investigators successfully produced urine both in a laboratory apparatus and after being transplanted into living animals.

Recent climate, glacier changes in Antarctica at the 'upper bound' of normal
In recent decades glaciers at the edge of Antarctica have thinned and research has shown the rate of thinning has accelerated and contributed significantly to sea level rise.

Freezing nerves knocks pain out cold
Using a tiny ball of ice, a minimally invasive interventional radiology treatment called cryoneurolysis safely short circuits chronic pain caused by nerve damage, according to data being presented at the Society of Interventional Radiology's 38th Annual Scientific Meeting in New Orleans.

Malaria elimination strategies should adapt to changing patterns of infection
Malaria control strategies must keep up with the rapidly changing patterns of malaria infection in low transmission settings, according to the authors of a new Review, published in The Lancet.

Bacterial security agents go rogue
CRISPR, a system of genes that bacteria use to defend themselves against viruses, has been found to be involved in helping some bacteria evade the mammalian immune system.

Nanosponges soak up toxins released by bacterial infections and venom
Engineers at the University of California, San Diego have invented a

Cutting specific pollutants would slow sea level rise
With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow down sea level rise.

New insight into accelerating summer ice melt on the Antarctic Peninsula
A new 1000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost 10-fold, and mostly since the mid 20th Century.

Stenting blocked bowel arteries saves lives
Stenting reopens completely blocked bowel arteries, preventing damage and even death from a condition that causes individuals severe pain and leads to excessive weight loss, notes research being presented at the Society of Interventional Radiology's 38th Annual Scientific Meeting in New Orleans.

Electrical pulse treatment pokes holes in hard-to-treat tumors
A new, minimally invasive treatment that tears microscopic holes in tumors without harming healthy tissue is a promising treatment for challenging cancers, suggests a preliminary study being presented at the Society of Interventional Radiology's 38th Annual Scientific Meeting in New Orleans.

Mount Sinai study identifies new gene variations associated with heart rate
A new study from Mount Sinai researchers to be published in Nature Genetics identifies 14 new genes that are associated with heart rate and may provide insight into the treatment of cardiovascular disease.

Icy therapy spot treats cancer in the lung
Frozen balls of ice can safely kill cancerous tumors that have spread to the lungs, according to the first prospective multicenter trial of cryoablation.

Gene sequencing project finds new mutations to blame for a majority of brain tumor subtype
The St. Jude Children's Research Hospital -- Washington University Pediatric Cancer Genome Project has identified mutations responsible for more than half of a subtype of childhood brain tumor that takes a high toll on patients.

Personalizing prostate specific antigen testing may improve specificity, reduce biopsies
Genetic variants have been identified which can increase serum prostate specific antigen (PSA) concentrations and prostate cancer risk.

Ordinary skin cells morphed into functional brain cells
Researchers at Case Western Reserve School of Medicine have discovered a technique that directly converts skin cells to the type of brain cells destroyed in patients with multiple sclerosis, cerebral palsy and other so-called myelin disorders.

Drug-coated stents prevent leg amputation
Drug-eluting stents can keep clogged leg arteries open, preventing amputation of the leg, suggests research being presented at the Society of Interventional Radiology's 38th Annual Scientific Meeting in New Orleans.
