Supercooling Could Extend Organs’ Viability


Supercooling Could Extend Organs’ Viability

A new technique for “supercooling” organs could preserve donor organs for days, allowing doctors more time to match them to suitable transplant candidates. Currently, doctors have a day or less to get a liver into a recipient, but in tests on rats, the new process kept livers viable for three days, a vast improvement. Rat livers are considerably smaller than human ones—0.35 oz (10 g) compared to 3.3 lb (1.5 kg)—and it remains to be seen whether scientists can scale up the technology and whether it will be able to preserve other organs as well.

Tanning Appears Addictive (CRIMINALIZING EVERYTHING LATELY? lIKE TANNING= ADDICTIVE?)


Tanning Appears Addictive

That “healthy glow” many love has proved to be less than healthy—the link between excessive ultraviolet (UV) exposure and skin cancer is well established—so why do they continue to tan? One possibility is that they are addicts. Researchers found that chronic exposure to UV radiation triggers the release of endorphins, so-called feel-good hormones, in mice. The regular exposure leads to physical dependence so strong that the animals exhibit withdrawal symptoms like shaking, tremors, and teeth chattering when those endorphins are blocked. Mice and humans have a similar biological response to UV exposure, meaning that tanning may be similarly addictive in people. More… Discuss
