This finding challenges traditional views on nanoparticle toxicity and suggests humans have been exposed to these particles for millennia.
A study published in Current Biology found that human children consistently chose to cooperate with others over working alone, whereas chimpanzees showed no such preference. The researchers suggest that this behavioral difference may be rooted in small motivational differences between humans and other species.
In a study of wild field crickets, males are found to protect females from predators, increasing their chances of survival. In exchange, paired males sire more offspring with each partner, suggesting that this 'chivalry' may have evolutionary benefits. The findings challenge traditional interpretations of male guarding behavior.
A new study found that teenagers experience more arguments with family members on days when they had conflicts with peers, and vice versa. Family fights lasted longer than peer conflicts, affecting relationships for up to two days later.
Hypothetical questions used in jury selection and political polling can create bias or entrench existing beliefs. Researchers found that pre-trial questioning can actually introduce bias, making it essential to recognize the potential for influence.
A UCLA study found that hysterectomized women have higher brain iron levels than non-hysterectomized women, comparable to men. This may explain why men develop age-related neurodegenerative diseases earlier than women. The research suggests that reducing peripheral iron levels could lower disease risk and improve brain health.

A study by Brown University researchers found that people seeking a mate rarely express their political preferences, with women and lower-income individuals less likely to do so. However, once paired, spouses tend to share similar political views, suggesting a potential filter for compatible long-term relationships.
Researchers created a new mouse model of obsessive-compulsive disorder (OCD) that replicates both symptoms and treatment timing in humans. The model points to new treatments, including blocking serotonin receptors or using an activator, which may be more specific and work faster than current therapies.

Researchers found that second-grade students from diverse backgrounds are aware of ethnicity-based stigma and experience higher academic anxiety. However, strong social connections at school can mitigate these effects and boost interest in academics.
Gina Turrigiano's concept of synaptic scaling resolves the paradox of maintaining stability and flexibility in neurons. Her laboratory has shown that neurons can 'tune' themselves by adjusting excitatory synaptic strengths to control output, while maintaining relative input strengths.
Researchers found that adventurous females prefer mates with similar outgoing personalities, regardless of physical attributes. This study provides evidence that compatible personalities play a crucial role in partner choice in non-human species.
Scientists discovered that the intestinal membrane receptor protein, GC-C, is also expressed in critical brain areas. The study found that GC-C's activation amplifies dopamine responses, leading to hyperactivity and attention deficits in mice. Treatment with a PKG activator reversed these behavioral problems.

This finding has significant implications for various mental health conditions, including obesity and depression.
A new framework for the evolutionary analysis of the mind proposes that humans cannot be accurately portrayed as being adapted only to a Stone Age environment due to recent selection of genes. Experimental evidence suggests that humans utilize general learning rules rather than a modular account of cognition.

Researchers at the University of Exeter have developed a system to anticipate high-risk climate tipping points, providing early warning systems for devastating consequences. By analyzing observational data, scientists can identify signs of instability in climate systems, allowing for forewarning and adaptation.
As people age, their brain responses to morally laden scenarios change, with adults showing reduced punishment for accidental harm and increased empathy. Young children's brains are more activated by emotional responses, but gradually develop cognitive processes that improve moral judgments.
A study at the University of Cambridge found that compulsions lead to obsessions, challenging the traditional understanding of obsessive-compulsive disorder (OCD). The research provides insight into the debilitating repetitive behavior of OCD and could lead to more effective treatments.
