Chimps focus on positive relationships in old age
As they get older, wild chimpanzees seek interactions with other group members in increasingly positive ways, a new study shows. Humans prioritize close, positive relationships during aging, which can support physical and mental health. The researchers have now found these social aging behaviors in wild chimpanzees. The study, published in Science , uses data from the Kanyawara chimpanzee communi

Leaving more big fish in the sea reduces CO2 emissions
Leaving more big fish–like tuna, sharks, mackerel and swordfish–in the sea reduces the amount of carbon dioxide (CO2) released into the Earth's atmosphere.This is because when a fish dies in the ocean it sinks to the depths and sequestrates all the carbon it contains with it. This is a form of 'blue carbon'. Big fish are about 10 to 15 percent carbon.

Ny metod kan utvärdera läkemedel mot alzheimer
Lundaforskare har tagit fram en metod som kan mäta effekten av olika lovande läkemedel mot Alzheimers sjukdom. Med den nya metoden har de kunnat se att en specifik läkemedelskandidat hindrar bildningen av de små proteinklumpar som tros skada nervcellerna i hjärnan. Forskarna hoppas nu att deras metod kan underlätta utvecklingen av nya läkemedel mot demenssjukdomen.
