Overall, men are at greater risk of heart attack than women, but several studies have suggested that certain risk factors have more of an impact on the risk in women than in men.

To look more closely at this association, researchers looked at data on almost half a million people enrolled in the UK Biobank - a database of biological information from British adults.

The 471,998 people had no history of cardiovascular disease, were aged 40 to 69 years and 56% of them were women.

Osaka, Japan - Technological advances have enabled scientists to obtain massive amounts of data on different information-carrying molecules in cells and tissues, such as DNA, proteins and various forms of RNA. However, to date, it has been difficult to perform integrated analyses of such information to further our knowledge on the molecules and processes involved in the development of particular diseases.

Young men who are overly preoccupied with building muscle have a significantly higher risk of depression, weekend binge drinking, and dieting that is not connected to obesity.

They also have four times the probability of using legal and illegal supplements, and anabolic steroids, a new study from the Norwegian University of Science and Technology (NTNU) and Harvard University has shown.

The study also shows that ten per cent of men have what is thought of as the more common type of body image disorder. That is, they think they are too fat and want to be thinner.

A study published in The Lancet HIV shows that HIV-2 is more pathogenic than previously demonstrated. The new findings indicate that early treatment should be applied to all patients with HIV, not only to those with HIV-1.

A pioneering technique designed to spot differences between immune cells in tumours could speed the development of cancer treatments, research suggests.

Scientists say the approach could be used to help doctors choose the best treatments for individual patients and predict which tumours are likely to respond to a particular therapy.

Menlo Park, Calif. -- Despite its role in shaping life as we know it, many aspects of photosynthesis remain a mystery. An international collaboration between scientists at SLAC National Accelerator Laboratory, Lawrence Berkeley National Laboratory and several other institutions is working to change that. The researchers used SLAC's Linac Coherent Light Source (LCLS) X-ray laser to capture the most complete and highest resolution picture to date of Photosystem II, a key protein complex in plants, algae and cyanobacteria responsible for splitting water and producing the oxygen we breathe.

For the first time, a team of astronomers has observed several pairs of galaxies in the final stages of merging together into single, larger galaxies. Peering through thick walls of gas and dust surrounding the merging galaxies' messy cores, the research team captured pairs of supermassive black holes--each of which once occupied the center of one of the two original smaller galaxies--drawing closer together before they coalescence into one giant black hole.

The human genome has its own proofreaders and editors, and their handiwork is not as haphazard as once thought.

Observations by ALMA and data from the MUSE spectrograph on ESO's VLT have revealed a colossal fountain of molecular gas powered by a black hole in the brightest galaxy of the Abell 2597 cluster -- the full galactic cycle of inflow and outflow powering this vast cosmic fountain has never before been observed in one system.

What started as Ninad Oak's side project turned out into something much larger, his doctorate thesis.

"The project started as my qualifying exam that I proposed at the end of my first year of graduate school," said Oak, a graduate student in molecular and human genetics in Dr. Sharon E. Plon's lab. "This was an off topic qualifying exam at the time, meaning the lab had not worked on this topic before."

A University of Kent study into post partum depression found the odds of developing this condition increased by 79% when mothers had baby boys compared to baby girls.

Overall the researchers identified that women who give birth to males are 71-79% more likely to develop post partum depression. Furthermore, women whose births had complications were 174% more likely to experience post partum compared to those women who had no complications.

EUGENE, Ore. -- Nov. 6, 2018 -- Researchers at the University of Oregon have identified a novel protein secreted by a common gut bacterium in zebrafish that reduces inflammation in the gut and delays death by septic shock.

By examining how the protein, Aeromonas immune modulator (AimA), mutually benefits both the bacteria and their larval zebrafish hosts, the research team's experiments shed light on how animals and their resident microbes negotiate a moderated level of inflammatory response.

Hypotrichosis simplex leads to progressive hair loss already in childhood. A team of researchers led by human geneticists at the University Hospital of Bonn has now deciphered a new gene that is responsible for this rare form of hair loss. Changes in the LSS gene lead to impairment of an important enzyme that has a crucial function in cholesterol metabolism. The scientists now present their findings in the renowned journal the American Journal of Human Genetics.

Scientists at Scripps Research have made a surprising discovery in their mission to understand how cells stay healthy, uncovering an important connection between a cell's sugar metabolism and its antioxidant response, one of the cell's key mechanisms to protect itself from oxidative stress and other damaging agents.

Adults who sleep just six hours per night -- as opposed to eight -- may have a higher chance of being dehydrated, according to a study by Penn State.

These findings suggest that those who don't feel well after a night of poor sleep may want to consider dehydration -- not simply poor sleep -- as a cause, and drink more water.

Results of the study are published in the journal SLEEP on Nov. 5.
