A new link has been identified between obesity in childhood and the lowering of the age of puberty.
The research which discovered the link, carried out at Plymouth University Peninsula Schools of Medicine and Dentistry, is published in the Journal of Clinical Endocrinology and Metabolism.
Despite saving thousands of lives yearly, nearly half of organ transplant surgeons report a low sense of personal accomplishment and 40 percent feel emotionally exhausted, according to a new national study on transplant surgeon burnout.This image shows senior staff psychologist Michelle Jesse, Ph.D., Henry Ford Hospital.

Using the body's natural virus killers to prevent and treat HIV infection has been problematic until now because of the strong inflammatory response these molecules can arouse as they get rid of the invaders. Now, collaborative research conducted by scientists at the Weizmann Institute and the National Institutes of Health (NIH) have demonstrated how suppressing the activity of these molecules – interferons – around the time of infection could have long-term implications for the course of the disease. Their research appeared in Nature.
RENO – Norwegian explorer Roald Amundsen became the first man to reach the South Pole in December of 1911. More than 100 years later, an international team of scientists led by Joe McConnell of Nevada's Desert Research Institute (DRI) have proven that air pollution from industrial activities arrived long before.
A new study has found that following a healthy lifestyle may lower childhood cancer survivors' risk of developing the metabolic syndrome. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings indicate that children with cancer and adults who had cancer when they were children should receive information about how their lifestyle may influence their long-term health.
A new in vitro study has revealed that nicotine and cotinine, a metabolite of nicotine, can potentially inhibit DNA damage caused by a certain carcinogen in smoke.
Dinosaurs might have survived the asteroid strike that wiped them out if it had taken place slightly earlier or later in history, scientists say.
A fresh study using up-to-date fossil records and improved analytical tools has helped palaeontologists to build a new narrative of the prehistoric creatures' demise, some 66 million years ago.
They found that in the few million years before a 10km-wide asteroid struck what is now Mexico, Earth was experiencing environmental upheaval. This included extensive volcanic activity, changing sea levels and varying temperatures.
In one of the largest prevalence studies to date, researchers from the U.K. provide national, regional, and global genotype prevalence estimates for the hepatitis C virus (HCV). Findings published in Hepatology, a journal of the American Association for the Study of Liver Diseases, indicate that genotype 1 is the most prevalent worldwide, with over 83 million patients infected of which one-third reside in East Asia. Genotype 3, at just over 54 million cases, is the next most prevalent, followed by genotypes 2, 4, 6, and 5.
Giving parents access to a website containing information about the measles, mumps and rubella (MMR) vaccine is the most cost-effective way of increasing its uptake, new University of Leeds research has found.
Oxford University scientists have shown that a powerful drug given at the time of a kidney transplant operation not only halves the early risk of rejection, but that it also allows a less toxic regimen of anti-rejection drugs to be used after the operation.
Two new pill-only antiviral drug regimens could provide shorter, more effective treatment options with fewer side effects for the majority of patients infected with hepatitis C, even those most difficult to treat, according to the results of two studies published in The Lancet.
Both studies focused on hepatitis C genotype 1, which is the most common genotype in the USA, Europe, North Asia, Australia, and South America, and one of the most difficult to treat.
The first systematic analysis of hepatitis E virus (HEV) transmission by blood components indicates that about 1 in 3000 donors in England have HEV in their plasma. The findings, published in The Lancet, suggest that around 1200 HEV-containing blood components (eg, red cells, platelets, and fresh frozen plasma) are likely to be transfused every year in England.
DURHAM, N.C. -- Microorganisms like bacteria and fungi can evade treatment by acquiring mutations in the genes targeted by antibiotics or antifungal drugs. These permanent mutations were once thought to be the only way for drug-resistant strains to evolve. Now a new study has shown that microorganisms can use a temporary silencing of drug targets -- known as epimutations -- to gain the benefits of drug resistance without the commitment.
Many studies have shown the potential for global climate change to cut food supplies. But these studies have, for the most part, ignored the interactions between increasing temperature and air pollution — specifically ozone pollution, which is known to damage crops.
A new study involving researchers at MIT shows that these interactions can be quite significant, suggesting that policymakers need to take both warming and air pollution into account in addressing food security.
Scientists from The University of Manchester have discovered why medication to treat asthma and pneumonia can become ineffective.
The findings, published in Nature Medicine, show that drugs widely used to treat lung diseases work with the body clock.
In the UK pneumonia, which is caused by an infection, affects around 1 in 1000 adults each year and is more serious for babies, young children, the elderly, smokers and those with an underlying health condition.
