Oldest-known aquatic reptiles probably spent time on land
A comprehensive analysis of Mesosaurus fossils shows that bones from adults share similarities with land-dwelling animals -- suggesting older Mesosaurus were semi-aquatic, whereas the...
The walking dead: Fossils on the move can distort patterns of mass extinctions
Using the fossil record to accurately estimate the timing and pace of past mass extinctions is no easy task, and a new study highlights...
World speed record for polymer simulations shattered by over a hundred-fold
By analogy to linear polymers, which reptate with a random walk embedded in a 3D network, we show that star polymers relax by a...
Dietary fiber reduces brain inflammation during aging
As mammals age, immune cells in the brain known as microglia become chronically inflamed. In this state, they produce chemicals known to impair cognitive...
How skin begins: New research could improve skin grafts, and more
Researchers have discovered a key mechanism by which skin begins to develop in embryos.
Gut microbes’ role in mammals’ evolution starts to become clearer
Scientists have made a key advance toward understanding which of the trillions of gut microbes may play important roles in how humans and other...
We have more than enough calories, but what about other nutrients?
A new study is the first to quantitatively map the flow of energy, protein, fat, essential amino acids and micronutrients from 'field-to-fork' at a...
Probiotic use may reduce antibiotic prescriptions
The use of probiotics is linked to reduced need for antibiotic treatment in infants and children, according to a review of studies that probed...
Geologists reveal ancient connection between England and France
The British mainland was formed from the collision of not two, but three ancient continental land masses, according to new research.
