Bored mink snack between meals, lie awake in bed

Researchers at PLOS ONE found that caged mink consume fewer food treats when exposed to stimulating environments, such as water for wading. The study also showed that these animals sleep more soundly, contradicting the common notion of boredom leading to increased wakefulness.

A smoker's license: Too radical for tobacco control?

Experts Simon Chapman and Jeff Collin disagree on the need for a smoker's license, with Chapman arguing it would limit access to tobacco products and encourage quitting, while Collin argues it would stigmatize smokers and shift focus away from the industry

5 year olds are generous only when they're watched

Research found that children as young as five behave generously when recipients can see their actions, not when sharing with an anonymous recipient. They also preferred transparent containers to opaque ones, indicating strategic decision-making about generosity.

How does the brain measure time?

Researchers at the University of Minnesota's Center for Magnetic Resonance Research found a specific region of the brain, lateral intraparietal area (LIP), that measures time consistently even without external cues. LIP activity decreased at a constant rate between timed movements, suggesting an internal hourglass mechanism.

Survival of the shyest?

A new study by Professor Grant Brown and colleagues reveals that a fish's personality affects its ability to recall predator threats. Shy trout retain information about predator odors for up to eight days, while bold trout forget within 24 hours.

Immune cells make flexible choices

A team of researchers at the Weizmann Institute has discovered how immune cells produce a wide range of receptors to fight different diseases. By analyzing the genetic sequences of lymphocyte receptors in mice, they found that the flexibility and length of DNA segments play a crucial role in determining the likelihood of two distant se...

Strengthening a billion-dollar gene in soybeans

Researchers have identified multiple genes that contribute to soybean resistance against the soybean cyst nematode, which causes hundreds of millions of dollars' worth of damage each year. By understanding how these genes interact and regulate expression, scientists may develop new methods for engineering artificial stronger resistance.

The good, the bad, and the guilty: Anticipating feelings of guilt predicts ethical behavior

Research suggests that people anticipating negative feelings from guilt are more likely to exhibit sympathetic and moral traits. This can lead to better business decisions and less unethical behavior in the workplace. Guilt-proneness is linked to lower counterproductive work behaviors, even after controlling for other factors.
