Warming in the Tasman Sea a global warming hot spot
Oceanographers have identified a series of ocean hotspots around the world generated by strengthening wind systems that have driven oceanic currents, including the East Australian Current, polewards beyond their known boundaries.

Oxford, Harvard scientists lead data-sharing effort
Led by researchers at University of Oxford and the Harvard Stem Cell Institute at Harvard University, more than 50 collaborators at over 30 scientific organizations around the globe have agreed on a common standard that will make possible the consistent description of enormous and radically different databases compiled in fields ranging from genetics to stem cell science, to environmental studies.

Sonicating sperm -- the future of male contraception
The ideal male contraceptive would be inexpensive, reliable, and reversible.

UCLA astronomers solve mystery of vanishing electrons
UCLA researchers have explained the puzzling disappearing act of energetic electrons in Earth's outer radiation belt using data collected from a fleet of orbiting spacecraft.

Stealthy leprosy pathogen evades critical vitamin D-dependent immune response
UCLA researchers discovered that the leprosy pathogen Mycobacterium leprae was able to evade immune activity that is dependent on vitamin D, a natural hormone that plays an essential role in the body's fight against infections.

Genetic regulation of metabolomic biomarkers - paths to cardiovascular diseases and type 2 diabetes
The research group at the Institute for Molecular Medicine Finland has revealed eleven new genetic regions associated with the blood levels of the metabolites, including new loci affecting well-established risk markers for cardiovascular disease and potential biomarkers for type 2 diabetes.

The good news about carbon storage in tropical vegetation
Tropical vegetation contains 21 percent more carbon than previously thought.

Sexual healing? Not likely
A new study shows the production of sperm is more biologically taxing than previously thought, and expending energy on it has significant health implications.

Cancer sequencing initiative discovers mutations tied to aggressive childhood brain tumors
Researchers studying a rare, lethal childhood tumor of the brainstem discovered that nearly 80 percent of the tumors have mutations in genes not previously tied to cancer.

Body clock receptor linked to diabetes in new genetic study
A study published in Nature Genetics today has found new evidence for a link between the body clock hormone melatonin and Type 2 diabetes.

Lifelong payoff for attentive kindergarten kids
Attentiveness in kindergarten accurately predicts the development of

That which does not kill yeast makes it stronger
Cells trying to keep pace with constantly changing environmental conditions need to strike a fine balance between maintaining their genomic integrity and allowing enough genetic flexibility to adapt to inhospitable conditions.

What do killer whales eat in the Arctic?
Killer whales are the top marine predator. The increase in hunting territories available to killer whales in the Arctic due to climate change and melting sea ice could seriously affect the marine ecosystem balance.

Differences in systolic blood pressure between the left and right arm could indicate vascular disease and increased likelihood of death
Differences in blood pressure between a person's left and right arm could indicate that the patient has vascular disease and is at increased risk of death.

Ultrasound male contraceptive, overlooked for decades, confirmed to work
Research released today confirms that therapeutic ultrasound, the same type used by physical therapists, can provide long-acting, non-invasive contraception, when applied to the testes in sessions of as little as 15 minutes.

Genetics study reveals how bacteria behind serious childhood disease evolve to evade vaccines
Genetics has provided surprising insights into why vaccines used in both the UK and US to combat serious childhood infections can eventually fail.

2-arm blood pressure check indicator for risk from heart disease or death
A systematic review and meta-analysis carried out by researchers at the University of Exeter Peninsula College of Medicine and Dentistry has found that differences in systolic blood pressure between arms could be a useful indicator of the likelihood of vascular risk and death.
