Pig hearts kept alive outside the body for more than 24 hours offers hope for many humans needing a transplant

A major bottleneck on human heart transplantation are limits to storage of the donor heart outside the body, which is currently only routinely possible for six hours. Scientists have now tested new preservation methods, to keep pig hearts routinely alive outside the body for at least 24 hours. If successfully extended to humans, this would constitute a significant improvement to clinical practice.

Scientists discover how caterpillars can stop their bleeding in seconds

Materials scientists have now shown how the blood-like hemolymph of tobacco hornworm caterpillars forms clots to stop bleeding. They show that outside the body, hemolymph can instantaneously change from water-like behavior to become ‘viscoelastic’ like saliva, that is, combining viscosity with elasticity. This discovery could have medical applications, if drugs can be designed that induce a similar change in human blood, to make it clot faster.

Is your partner’s disturbed sleep keeping you up at night? Letting go of unattainable dreams may keep you both happy in bed

Research has now shown that the habit of letting go of unattainable goals helps people to stay satisfied with their romantic relationship if their partner experiences sleep problems. Such ‘letting go’ could also be learned, for example through training by clinical psychologists. But the results also showed that being too ready to replace unattainable goals with alternatives can worsen mutual satisfaction with a relationship, perhaps because this prevents spouses from putting more time and effort into it.

Living in poverty with chronic inflammation significantly increases heart disease and cancer mortality risk, study finds

People living in poverty in the US are known to suffer increased mortality, as are people with chronic inflammation. Now, researchers have shown in an epidemiological study that these effects are not simply additive but synergistic: people living in poverty with chronic inflammation ran a 127% increased heart disease mortality risk and a 196% increased cancer mortality risk when measured over 15 years.
