Mercury mineral evolution
Metformin may lower cancer risk in people with Type 2 diabetes
Mineral evolution posits that Earth's near-surface mineral diversity gradually increased through an array of chemical and biological processes. A dozen different species in interstellar dust particles that formed the solar system have evolved to more than 4500 species today. New work from Carnegie's Bob Hazen demonstrates that the creation of most minerals containing mercury is fundamentally...
Modified bariatric surgery provides remission of Type 2 diabetes
A commonly prescribed diabetes drug, metformin, reduces the overall cancer risk in people with Type 2 diabetes, a large systematic review study finds. The results will be presented Monday at the Endocrine Society's 94th Annual Meeting in Houston.
Mount Sinai researcher finds timing of ADHD medication affect academic progress
Type 2 diabetes often reverses after modified weight loss surgery, especially when the duration of diabetes is less than 10 years, a new study finds. The results will be presented Tuesday at the Endocrine Society's 94th Annual Meeting in Houston.
Mystery of the flatfish head solved
A team of researchers led by an epidemiologist at Mount Sinai School of Medicine and University of Iceland has found a correlation between the age at which children with attention-deficit/hyperactivity disorder begin taking medication, and how well they perform on standardized tests, particularly in math.
Nano-sandwich technique slims down solar cells, improves efficiency
A new discovery described in the latest issue of the Journal of Vertebrate Paleontology by Oxford University researcher Dr Matt Friedman describes a fossil fish, named Heteronectes (meaning "different swimmer") that was found in 50 million year old marine rocks from northern Italy. This study provides the first detailed description of a primitive flatfish, revealing that the migrated eye had not...
NASA sees Tropical Storm Debby's clouds blanket Florida
Researchers from North Carolina State University have found a way to create much slimmer thin-film solar cells without sacrificing the cells' ability to absorb solar energy. Making the cells thinner should significantly decrease manufacturing costs for the technology.
New evidence links ozone exposure to potential heart attacks
Like a white blanket, Tropical Storm Debby's clouds covered the entire state of Florida in a NASA satellite image. Two satellites have captured imagery that shows Tropical Storm Debby has thrown a large white blanket of clouds over the state of Florida, and it doesn't seem like that blanket is going to lift quickly as Debby moves slowly north.
New hormonal gel combination shows promise as reversible birth control for men
Young, healthy adults exposed to ozone for two hours developed changes in their cardiovascular system which could explain a possible link between ozone exposure and death. Exposure to ozone, along with particulate matter (tiny airborne particles inhaled into the lungs), may be a major cause of the two million annual acute air pollution deaths worldwide.
New tools for evaluating quality of life for cats, dogs with heart disease
Male hormonal contraceptives applied daily to the skin reduce sperm production, finds a new study to be presented Sunday at the Endocrine Society's 94th Annual Meeting in Houston.
Overweight men can boost low testosterone levels by losing weight
Veterinarians at the Cummings School of Veterinary Medicine have developed and tested tools for measuring quality of life among dogs and cats with heart disease.
Prions and cancer: A story unfolding
Weight loss can reduce the prevalence of low testosterone levels in overweight, middle-aged men with prediabetes by almost 50 percent, a new study finds. Results will be presented Monday at the Endocrine Society's 94th Annual Meeting in Houston.
Rate of severe reactions higher than thought in young children with food allergies
Prions, the causal agents of mad cow and other diseases, are very unique infectious particles. In a paper published in the Journal of Biological Chemistry, researchers in Brazil present new evidence that a prion-like behavior may be responsible for tumor formation and progression. The new finding may dramatically transform our way of thinking of cancer and treating cancer patients.
Remapping gang turf: Math model shows crimes cluster on borders between rivals
Young children with allergies to milk and egg experience reactions to these and other foods more often than researchers had expected, a study reports. The study also found that severe and potentially life-threatening reactions in a significant number of these children occur and that some caregivers are hesitant to give such children epinephrine, a medication that reverses the symptoms of such...
Removing estrogen from drinking water
A mathematical model that has been used for more than 80 years to determine the hunting range of wild animals holds promise for mapping the territories of street gangs, a UCLA-led team of social scientists reports in a new study. "The way gangs break up their neighborhoods into unique territories is a lot like the way lions, chimpanzees or honey bees break up space," said author P. Jeffrey...
Romancing the firefly
A biological filter to remove estrogen from waste water and drinking water. The 15 Bielefeld students submitting this project to the International Genetically Engineered Machine Competition at the Massachusetts Institute of Technology in Boston, USA, are setting their sights high. Since May, they have been spending their free time in the laboratory making new DNA building blocks, reproducing them,...
Safety fears and agism denying care home residents right to consensual sex
While a female firefly's initial assessment of potential mates is based on males' luminescent flashes, once a pair makes physical contact, sexy flashes no longer matter. Instead, it's males that have larger nuptial gifts (a protein-packed sperm package that helps females produce more eggs) that mate more often and father more offspring.
Scientists struggle with mathematical details
Concerns about safety, and ageism, are needlessly denying elderly care home residents what is often one of their few remaining pleasures - the right to consensual sex - say specialists in the Journal of Medical Ethics.
Scientists twist light to send data
Many people remember struggling with maths at school, but few of us would expect that professional scientists suffer from a similar problem in their daily work. A new study by biologists at the University of Bristol shows that scientists tend to overlook their colleagues' research if it is packed full of mathematical equations.
Severe reactions to food more common than thought in young children
A multi-national team led by USC with researchers hailing from the US, China, Pakistan and Israel has developed a system of transmitting data using twisted beams of light at ultra-high speeds -- up to 2.56 terabits per second.
Smallest and largest fetuses at greater risk of being stillborn, research finds
Young children with allergies to milk and egg experience an unexpectedly high number of reactions to these and other foods, according to researchers at National Jewish Health. More than 70 percent of preschool children with documented or suspected food allergies suffered a significant reaction during the three-year period. Researchers also found that caregivers failed to administer the medication...
Statins appear associated with reduced risk of recurrent cardiovascular events in men, women
The tiniest and the heaviest fetuses are at much higher risk of being stillborn than those of average weight, new research has found.
Stillbirth rate twice as high among least well off in England
Cholesterol-lowering statin drugs appear to be associated with reduced risk of recurrent cardiovascular events in men and women, but do not appear to be associated with reduced all-cause mortality or stroke in women, according to a report of a meta-analysis published June 25 in the Archives of Internal Medicine, a JAMA Network publication.
