Blood pressure lowering drugs do not improve life expectancy among adults with diabetes and kidney disease, a new study of the global evidence published today in The Lancet reveals.
Tropical rainforests have long been considered the Earth's lungs, sequestering large amounts of carbon dioxide from the atmosphere and thereby slowing down the increasing greenhouse effect and associated human-made climate change.
Astronomers using NASA's Hubble Space Telescope have uncovered surprising new clues about a hefty, rapidly aging star whose behavior has never been seen before in our Milky Way galaxy.

Alternative splicing of obesity and type 2 diabetes related genes may contribute to the pathophysiology of obesity, according to research from the University of Eastern Finland. Obesity leads to changes in the splicing pattern of metabolically relevant genes such as TCF7L2 and INSR, resulting in impaired insulin action.
Lawrence Livermore researchers have determined that a tunnel bomb explosion by Syrian rebels was less than 60 tons as claimed by sources.
Paralyzed from the neck down after suffering a gunshot wound when he was 21, Erik G. Sorto now can move a robotic arm just by thinking about it and using his imagination.
Scientists from IBM Research and the Universities of Melbourne and Queensland have moved a step closer to identifying the nanostructure of cellulose -- the basic structural component of plant cell walls.
Receptors carrying built-in decoys are the latest discovery in the evolutionary battle between plants and pathogens. The decoy domains within the receptor detect pathogens and raise the cell's alarm when there is an infection.
Researchers have discovered the 425-million-year-old fossil remains of a new species of parasite, still attached to the host animal it invaded long ago.
According to small and medium-sized enterprises, sizable social security and other wage-related costs still form the single greatest obstacle for improving productivity.
The first definitive summary of the best and safest blood pressure lowering treatments for kidney disease and diabetes patients has been compiled by New Zealand doctor and researcher Associate Professor Suetonia Palmer.
Two words that arouse immediate fear in some people inspire something else altogether in Jennifer Fill.
Limiting temperature rise by 2100 to less than 1.5¬°C is feasible, at least from a purely technological standpoint, according to the study published in the journal Nature Climate Change by researchers at the International Institute for Applied Systems Analysis (IIASA), the Potsdam Institute for Climate Impact Research (PIK), and others.
Increasing public knowledge and understanding about energy issues is vital if improved energy-saving behaviours are to be encouraged among individuals and organisations, a study suggests.
Many glaciers on the Southern Antarctic Peninsula (SAP) -- a region previously thought to be stable compared to other glacier masses in Antarctica -- became destabilized in 2009, and they have been melting at accelerating rates ever since, researchers say.
Researchers at Case Western Reserve University School of Dental Medicine have unraveled one of the mysteries of how a small group of immune cells work: That some inflammation-fighting immune cells may actually convert into cells that trigger disease.
A Dartmouth study finds that TV food commercials disproportionately stimulate the brains of overweight teen-agers, including the regions that control pleasure, taste and -- most surprisingly -- the mouth, suggesting they mentally simulate unhealthy eating habits.
Providing personalized education and risk assessment for patients with diabetes when they visit the ophthalmologist did not improve glycemic control as measured by hemoglobin A1c levels compared with patients who received usual care, according to a study published online by JAMA Ophthalmology.
Scientists from the Institut Pasteur and CNRS, in collaboration with scientists from the Institut Gustave Roussy and CEA, have succeeded in restoring normal activity in cells isolated from patients with the premature aging disease Cockayne syndrome.
Montana State University researchers and their collaborators have published their findings about a chemical compound that shows potential for treating rheumatoid arthritis.
A University of Wyoming faculty member led a research team that discovered a certain type of soil bacteria can use their social behavior of outer membrane exchange (OME) to repair damaged cells and improve the fitness of the bacteria population as a whole.
Urgent diagnosis and treatment in acute heart failure has been emphasised for the first time in joint recommendations published today in European Heart Journal.
Although eating high-protein, afternoon snacks can aid appetite control in adults, little information exists to guide parents on what types of snacks might benefit their adolescent children.
In the years following the 1986 Chernobyl nuclear disaster, forest fires billowed plumes of contaminated smoke, carrying radioactive particles throughout Europe on the wind.
Bacteria that live in the guts of cicadas have split into many separate but interdependent species in a strange evolutionary phenomenon that leaves them reliant on a bloated genome, a new paper by CIFAR Fellow John McCutcheon's lab (University of Montana) has found.
Crucial bodily functions we depend on but don't consciously think about -- things like heart rate, blood flow, breathing and digestion -- are regulated by the neurovascular unit.
A new article publishing online today in the Quarterly Journal of Medicine has reported the first case showing an association between exposure to head injuries in rugby union players and an increased risk in neurodegenerative disease.
A new study published by the team of Naguib Mechawar, Ph.D., a researcher at the Douglas Institute (CIUSSS de l'Ouest-de-l'√®le-de-Montr√©al) and Associate Professor in the Department of Psychiatry at McGill University, suggests that the integration of new neurons in the adult brain is a phenomenon more generally compromised in the brains of depressed patients.
Patients with insulin-dependent diabetes can better control their HbA1c value with a combination of blood glucose self-monitoring (BGSM) and continuous interstitial glucose monitoring (CGM) using a real-time measurement device (real-time CGM) than with BGSM alone without severe or serious hypoglycaemia occurring more frequently.

An association between resting heart rate and diabetes suggests that heart rate measures could identify individuals with a higher future risk of diabetes, according to an international team of researchers.

The sense of touch is important but often taken for granted in daily life because it seems simple and automatic. New research suggests that the apparent simplicity of tactile sensation comes from a clever two-stage brain circuit.

If a young man is a chronic gambler, the chances are extremely high that he also suffers from depression.
The widespread evolution of herbicide-resistant weeds is costing farmers, especially through decreases in productivity and profitability. Although researchers and industry personnel have made recommendations to slow this evolution, an understanding of the patterns and causes of the resistance has been limited.
