Battery developer Phinergy and metal manufacturer Alcoa have teamed up at Circuit Gilles Villeneuve in Montreal to demonstrate their aluminum-air battery in a small electric vehicle, which could make it travel 1,000 miles on a single charge. The test car, which appeared to be using the body of a Citroen C1, used lithium-ion and aluminum-air batteries for the run. But the question of whether or not it makes sense to take this little EV on a 1,000-mile road trip ...

Adolescents Seek Others Help to Talk It Out After Argument With Dad

Posted:

When an adolescent is having an argument with their father, they seek out others for help, finds a new study. And the response he or she receives is linked to better well-being and father-child relationships. Adolescents who receive a reason for the father's behavior or a better understanding of who is at fault feel better about themselves and about dad as well. Those feelings about dad, in turn, are linked to a lower risk of depression ...

Antimalarial Drug Atovaquone Prevents Malaria: Study

Researchers Reveal Black Holes Not Being Turbulent Theory

Posted:

The accepted wisdom about spacetime not being turbulent could be wrong, reveals a new research. Perimeter Faculty member Luis Lehner explains why it might make sense to treat gravity as a fluid. "There's a conjecture in physics - the holographic conjecture - which says gravity can be described as a field theory," he says. "And we also know that at high energies, field theories can be described with the mathematical tools we use to describe fluids. So it's a two-step ...

Cycles of Prolonged Fasting Triggers Stem Cell Regeneration of Damaged, Old Immune System

Posted:

A study shows that cycles of prolonged fasting not only protect against immune system damage but also induce immune system regeneration, shifting stem cells from a dormant state to a state of self-renewal. It is the first evidence of a natural intervention triggering stem cell-based regeneration of an organ or system. Immune system damage is a major side effect of chemotherapy. The study got published in the June 5 issue of the Cell Press journal iCell Stem Cell/i. ...
