João Pedro Magalhães, researcher in the Biology of Aging, suggests, in work published in the June edition of the magazine "Experimental Gerontology" and entitled "The evolution of mammalian aging", that the study of certain species of reptiles and amphibians that apparently do not age could lead to discoveries about aging.
For this Portuguese scientist the secret of eternal youth could be in the relationship, already scientifically shown, between the size and longevity of different species and the fact that animals of bigger species live longer and age more slowly.
According to these studies, carried out with the collaboration of Olivier Toussaint, the most accelerated examples of aging in mammals could be connected to the fact that after their evolution from reptiles they spent close to 100 million years as small animals and therefore with shorter longevity.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
