Scientists examining documents dating back 3,500 years say they have found proof that the origins of modern medicine lie in ancient Egypt and not with Hippocrates and the Greeks.

The research team from the KNH Centre for Biomedical Egyptology at The University of Manchester discovered the evidence in medical papyri written in 1,500BC – 1,000 years before Hippocrates was born.

ESA’s X-ray observatory XMM-Newton has revealed a new class of exploding stars – where the X-ray emission ‘lives fast and dies young’.

The identification of this particular class of explosions gives astronomers a valuable new constraint to help them model and understand stellar explosions.

The Fumanya site, in the Bergueda region of central Catalonia, is so delicate that experts cannot get physically close enough to the tracks to examine them.

In the years since the tracks were discovered they have been exposed to the elements, and as a result are severely weathered and eroding at a rapid rate.

To make things even more difficult, the tracks are imprinted into near-vertical rock faces.

Palaeontologists feared the tracks could be lost forever - but a permanent and detailed record has now been created using cutting-edge equipment.

Using a high-tech laser scanning system called RIEGL, researchers from The School of Earth, Atmospheric and Environmental have produced an interactive 3D model of a quarry face covered in thousands of tracks made by the late Cretaceous din

A research team led by Carole Thivierge, from Université Laval’s Institute of Nutraceutics and Functional Foods, shows that omega-3 fatty acids from fish oil have a positive effect on the metabolism of muscle proteins. This finding, published in a recent edition of the Journal of Physiology, could have significant implications in the fields of animal farming as well as human health.

As climate change becomes more and more a central issue in local, national, and international discussions, understanding the global carbon budget, and how it influences trends in global warming, will become increasingly crucial.

The carbon cycle is related to climate and climatic change because it controls carbon dioxide, the most important of the greenhouse gases. Dr. R. A. Houghton has authored a synthesis paper on the topic, summarizing what is known about the global carbon budget and why it is important. The work is featured in the current issue of the Annual Review of Earth and Planetary Science.

In the eternal conflict between friends and parents, friends will often win because they highlight the positive aspects of sex.

Parental communication more often than not focuses on the negative aspects of sex, write Marina Epstein and L. Monique Ward from The University of Michigan.
