“Off-the-shelf” patch boosts cardiac function by 50% in animal models

Cardiac patches are designed to help regenerate healthy heart tissue after the injury, and scientists at North Carolina State University have now developed an “off-the-shelf” version they say overcomes some of the dangers of other approaches.

Cancer-killing nanoparticles don disguises to sneak into the brain

The brain’s own defense mechanism often prevents treatment of brain cancers. But a new experimental treatment has shown success in mice, with carbon nanoparticles able to sneak through the blood-brain barrier and deliver drugs directly to tumors.

Even latest sonar tech may keep sperm whales from finding food

Sperm whales use echolocation to search for prey in the dark ocean – so it makes sense that competing sounds could screw that process up. A recent study now indicates that even a new-and-improved type of manmade sonar does indeed cause problems.

Scientists uncover metabolic mechanisms behind herbal “hangover cure”

Most people would tackle hangovers with plenty water and some greasy food, rather than a herbal remedy. But dihydromyricetin (DHM) does seem to have some effect, and now researchers from USC have investigated just how it works in the liver.

Simple new method makes graphene “paint” possible

Graphene may be versatile, but it’s not all that good at dispersing in water. Now, researchers at Umeå University have found a relatively simple way to do it – use graphene oxide instead, which can then be used as a kind of graphene paint.

Study suggests the ocean is soaking up twice as much CO2 as we thought

The world’s oceans play an important role in regulating the balance of CO2 in the atmosphere, but a new study suggests we may have been greatly underestimating the effectiveness of this vast carbon sink.
