Researchers from the University of Cambridge used a method similar to charging a battery to instead charge activated charcoal, which is often used in household water filters.By charging the charcoal ‘sponge’ with ions that form reversible bonds with CO2, the researchers found the charged material could successfully capture CO2 directly from the air. The charged charcoal sponge is also potentially more energy efficient than current carbon capture approaches, since it…

Restless leg syndrome can cause an unpleasant crawling sensation in the legs and an overwhelming urge to move them. Some people experience the symptoms only occasionally, while others get symptoms every day. Symptoms are usually worse in the evening or at night-time and can severely impair sleep.Despite the condition being relatively common – up to one in 10 older adults experience symptoms, while 2-3% are severely affected and seek medical…

Previous studies in both humans and animal models have shown that the offspring of mothers living with obesity have a higher risk of developing obesity and type 2 diabetes themselves when they grow up. While this relationship is likely to be the result of a complex relationship between genetics and environment, emerging evidence has implicated that maternal obesity in pregnancy can disrupt the baby’s hypothalamus—the region of the brain responsible…

The theory of coevolution says that when closely interacting species drive evolutionary changes in each other this can lead to speciation - the evolution of new species. But until now, real-world evidence for this has been scarce.Now a team of researchers has found evidence that coevolution is linked to speciation by studying the evolutionary arms race between cuckoos and the host birds they exploit. Bronze-cuckoos lay their eggs in the…
