A new study suggests that experiencing stressful events the day before eating a single high-fat meal can slow metabolism in women.

Researchers questioned study participants about the previous day's stressors before giving them a meal consisting of 930 calories and 60 grams of fat. The scientists then measured their metabolic rate, how long it took the women to burn calories and fat, and took measures of blood sugar, triglycerides, insulin and the stress hormone cortisol.

On average, the women in the study who reported one or more stressors during the previous 24 hours burned 104 fewer calories than nonstressed women in the seven hours after eating the high-fat meal – a difference that could result in weight gain of almost 11 pounds in one year.

Crop spraying on British farms could be aiding a life-threatening fungus suffered by tens of thousand of people in the UK each year.

New research by British and Dutch scientists has found that Aspergillus – a common fungus that attacks the lungs and is found in soil and other organic matter – has become resistant to life - saving drugs in parts of rural Yorkshire.

It's the first time a link has been made in the UK between drug resistance in Aspergillus and fungicide used on crops. Experts warn their findings, now published, are significant and raise serious implications for transplant patients, those with leukaemia and people who suffer from severe asthma.

You don't have a pre-pregnancy and your computer doesn't have a pre-power switch. Calling someone who has moderately high blood sugar a prediabetic is premature and creates unnecessary alarm and financial burdens. Imagine being at a party with gluten-free, HFCS-free, non-GMO, vegans who are now also pre-diabetic. Not fun. And worse, it has no value. A new analysis in BMJ sought to find out whether a "diagnosis" of pre-diabetes carried any health benefits such as improved diabetes prevention.

Researchers have created a combination drug that controls both tumor growth and metastasis. By combining a COX-2 inhibitor, similar to Celebrex, and an epoxide hydrolase (sEH) inhibitor, the drug controls angiogenesis (blood vessel formation), limiting a tumor's ability to grow and spread.

Both COX and sEH enzymes control lipid signaling, which has long been associated with inflammation, cell migration, proliferation, hypertension and other processes. COX inhibitors block production of inflammatory and pain-inducing lipids, while sEH inhibitors preserve anti-hypertensive, anti-inflammatory and analgesic compounds. Separate COX and sEH inhibitors were previously found to work together in reducing inflammation and neuropathic pain.

Young women who post sexy or revealing photos on social media sites are regarded by female peers as less competent to perform tasks, less physically attractive and less socially attractive, a new study indicates.

"This is a clear indictment of sexy social media photos," said researcher Elizabeth Daniels, an assistant professor of psychology Oregon State University and co-author of the paper. Daniels' findings are based on an experiment she conducted using a fictitious Facebook profile. "There is so much pressure on teen girls and young women to portray themselves as sexy, but sharing those sexy photos online may have more negative consequences than positive."

Circulating tumor cells spread ovarian cancer through the bloodstream, homing in on a sheath of abdominal fatty tissue where it can grow and metastasize to other organs, according to a new paper.

The researchers found the circulating tumor cells (CTCs) rely on HER3, a less-famous sibling of the HER2 receptor protein prominent in some breast cancers, to find their way to the omentum, a sheet of tissue that covers and supports abdominal organs. HER3's heavy presence on these cells makes it a biomarker candidate and suggests possible therapeutic options to thwart ovarian cancer progression, the researchers noted.

High expression of HER3 in ovarian cancer tumors is associated with shorter survival, the team found.
