Sad movies are bad news for diets. A newly reported study from the Cornell Food and Brand Lab showed movie-goers watching tearjerkers ate between 28% and 55% more popcorn both in the lab and in a mall theater during the Thanksgiving holiday.

According to findings published in a JAMA Internal Medicine research letter, movie goers ate 28% more popcorn (125 versus 98 grams) when watching the tragedy Love Story than when watching the comedy Sweet Home Alabama.

Two studies scheduled for presentation at the American College of Cardiology's 64th Annual Scientific Session in San Diego failed to find a connection between testosterone therapy in men and heart problems, contradicting research that prompted the U.S. Food and Drug Administration to investigate its safety. The new studies include a meta-analysis of data from 29 studies involving more than 120,000 men and an observational study from a Wisconsin health system.

A low-cost antiseptic used to cleanse the cord after birth could help reduce infant death rates in developing countries by 12%, a systematic review published in The Cochrane Library suggests. Authors of the review found that when chlorhexidine was used on babies born outside of a hospital, it reduces the number of newborn babies who died or suffer from infections.

Gout appears to have a protective effect for the brain, possibly thanks to uric acid, the chemical in a person's blood that can crystallize, leading to gout, said a team of researchers from north America.

Gout, the most common inflammatory arthritis, is linked to a higher risk of heart and kidney problems and their resulting health issues, but previous studies have theorised that the antioxidant properties of uric acid may protect against the development or progression of neurodegenerative conditions such as Parkinson's disease (PD).

Obesity, hypertension and diabetes are known risk factors for heart failure, a chronic condition in which the heart cannot pump enough blood to meet the body's needs. For the first time, scientists have quantified the average number of heart failure-free years a person gains by not developing those risk factors by age 45, according to a study scheduled for presentation at the American College of Cardiology's 64th Annual Scientific Session in San Diego.

Most of the times we have looked at Uranus, it has seemed to be a relatively calm place. Well, yes its atmosphere is the coldest place in the solar system.

But, when we picture the seventh planet in our solar system invariably the image of a calming blue hazy disc that the spacecraft Voyager 2 took in 1986 comes to mind.

However, all we have previously known about the atmosphere of Uranus has been ’thrown to the wind’ with observations made last year.

A trained scent dog has been found to accurately distinguish between benign and cancerous urine samples of thyroid cancer patients a terrific 88.2 percent of the time, according to a new study.

That canine diagnostic accuracy is only slightly less than that of fine-needle aspiration biopsy, the method generally used first to test thyroid nodules for cancer - but it is noninvasive and inexpensive. 

An experimental compound known as GC-1 causes loss of weight and fat in mice in lab tests. The drug speeds up metabolism, or burning off, of fat cells, by activating the receptors for thyroid hormone, which play a role in regulating metabolism - the body's conversion of food into energy. Thyroid hormone receptors also help with adaptive thermogenesis, in which the body converts excess energy (calories and fat) to heat.

Until recently, there was no evidence that human adults had  energy-burning, "good" brown fat. It was only known that animals and human infants did  but now it is known that human adults do have brown fat, but it appears to lose its calorie-burning activity over time.

Attempts to put a dollar value on the natural world – so-called “natural capital” or “ecosystem services” – have produced some frankly staggering numbers. A seminal 1997 paper valued the world’s ecosystem services at US$33 trillion (A$42 trillion) a year. This estimate was controversial, given that it dwarfed the entire global market economy, which at the time stood at roughly US$18 trillion a year.

New research published in Diabetologia shows that use of statins is associated with a 46% increase in the risk of developing diabetes, even after adjustment for confounding factors. The study is by Professor Markku Laakso, Institute of Clinical Medicine, University of Eastern Finland and Kuopio University Hospital, Finland, and colleagues.
