The remains of a pregnant Tyrannosaurus rex that had died in ancient Montana about 68 million years ago may provide hints into how to identify male and female theropods, or bipedal meat-eating dinosaurs.

In a new study, researchers said they looked at the organic components in the dinosaur’s bone structure and after verify details of the fossil, reached at the conclusion that the T. rex was pregnant. The bone structure had survived for tens of millions of years since the predator’s death.

Mary Schweitzer, an evolutionary biologist at North Carolina State University and study lead researcher, said the T. rex was discovered in 2000 by Bob Harmon, a paleontologist at the Museum of the Rockies in Montana, Hell Creek Formation.

A report written by Lancet Neurology Commission will guide politicians and policy makers about the challenges of Alzheimer's disease. The paper will be brought forth today to provide expert recommendations and information about the disease. The report will be published in the April issue of the journal Lancet Neurology. The 78-page report is a coordinated effort of 30 internationally leading researchers.

The report, which has plans that could help fight Alzheimer's disease, will be presented today on 15th March during the Brain Awareness Week 2016 at a workshop hosted by the European Parliament in Brussels. Professor Bengt Winblad, Centre for Alzheimer Research at Karolinska Institutet in Sweden, is lead author of the report.

Today is National Napping Day in the US, and on this occasion, worldwide scientists argued that a quick snooze in the day time has many benefits that most of us aren’t aware of.

Napping day assists people in the US to adjust after daylight savings take effect, as per the Days of the Year. In most of the world, nap is an integral part of the cultural practice, and isn’t just an event due to ‘spring forward’.

A breakthrough development could save lives of millions of people in America suffering from heart disease and failure.

Every year, over half a million people lose their lives in the United States due to heart failure, and thousands of them waiting for a suitable transplant. However a new scientific paper has come up with a potential answer to this deficiency: growing new ones.

A team of researchers at Massachusetts General Hospital’s Center for Regenerative Medicine (CRM) decided to do so. Published in the journal Circulation Research this week, their work proved that the idea can possibly become a game changer. The researchers used skin cells reprogrammed into stem cells for to produce functional heart tissue.

On Tuesday, the United States Food and Drug Administration (FDA) is going to review Abbott's one-of-a-kind dissolving medical implant to evaluate its possible risks for the patients of heart attack and blood clot.

Abbott has requested FDA to approve its novel coronary stent, known as Absorb, as a substitute to metal stents, which has been in use for the treatment of narrowing arteries that generally result into heart attack or death.

Abbott's Absorb isn’t like traditional bare-metal stents that stay in place. Instead, it disappears within the body in a time span of three years after clearing fat-clogged arteries.

The family of a three-year-old brain cancer patient said that the simple act of receiving mail has been brightening the little girl’s days. At age of 4 months, Ellie Walton got diagnosed with brain tumor. The girl is now three, and has undergone more than 13 brains surgeries, as per her mother, Sarah Walton. Presently, the toddler is battling glioblastoma multiforme, which is a deadly type of brain cancer.

Walton said that during the past some months, the family has found an unusual and unexpected way of cheering up Ellie: postcards.
