Researchers found that orangutans prefer food linked to sounds of laughter from their peers. The study showed that hearing laughter made the apes value the food more, suggesting emotions affect how they learn and make choices.
Key Facts
Scientists studied six orangutans in zoos to see if sounds influenced their food choices.
Orangutans were trained to find treats hidden under different substances like moss or sawdust.
Before choosing, orangutans heard recordings of either laughter or neutral environmental sounds.
Four out of six orangutans chose food associated with the laughter sound.
The findings suggest positive emotions like joy affect how orangutans learn and remember.
Researchers believe this emotional effect on learning also applies to humans, for example, in education.
Being in a good mood might make people value information more and affect their preferences for subjects.
The study helps understand the link between emotions and rational decision-making in animals and people.

Russia is sending its first tanker with diesel fuel to the United States as part of a deal to help lower high fuel prices before the November midterm elections. However, experts say this shipment is small compared to US fuel needs and likely won’t reduce prices much in time for the elections.

The shipment is part of a larger plan to increase Russian fuel exports to the US.
Russia faces its own fuel shortages caused by attacks on its refineries.

Federal changes to the hepatitis B vaccine recommendations removed the rule to vaccinate all newborns, which may lead to more infections in children and leave millions vulnerable. A recent study shows that delaying vaccination or making it optional based on shared decisions could increase cases of chronic hepatitis B.
Key Facts

Since newborn vaccination began in 1991, infant infections have dropped by 99%.
Researchers modeled the impact on 3.6 million U.S. babies born in 2026.
Delaying the vaccine until 2 months could increase chronic infections by 19%.
Using shared decision-making instead of routine vaccination might raise infections by 83%.
Up to 1.8 million young adults could be vulnerable to hepatitis B due to these changes.
