Social media is often accused of turning political debates into toxic battlegrounds, but new research provides evidence that offline social inequalities actually play a role in shaping this digital aggression. The findings suggest that users from less democratic and economically unequal countries perceive significantly more political hostility online than users from more egalitarian countries. This study nature human behavior. When the Internet first emerged, many observers expected it to create a more equal and inclusive public sphere. This optimism extended to authoritarian regimes, with early social media platforms sometimes seen as tools for democratic uprisings. But today, political discussion on…
General intelligence does not appear to influence specific mental skills uniformly over an individual’s lifetime or across different levels of mental ability. A large-scale study published in the journal Psychology and Aging found that the connections between different cognitive skills fluctuate significantly with age, with those connections becoming significantly weaker in people with higher overall intelligence. These changing patterns suggest that a single overall IQ score may be less reliable as a measure of brain power for certain people, depending on age and baseline ability. In the field of psychology, researchers have observed that cognitive abilities tend to be related.…
An in-depth look at eleven pivotal clinical trials for 2026, covering gene editing, vaccines, AI integration, and platform trial methodologies.
As we age, recovery from muscle damage often slows, and scientists may have discovered an important reason why. A new UCLA study conducted in mice found that aging muscle stem cells accumulate high levels of proteins that slow their ability to activate and repair damaged tissue. At the same time, the protein appears to help cells withstand the difficult conditions found in aging muscle. Research published in journals sciencesuggests that some biological changes associated with aging may be more than just signs of decline. Rather, they may function as a protective adaptation that helps cells survive. “This leads us to…
Discovery of floating bottle carrying crustacean hitchhiker helps researchers learn more about the impact of plastic pollution on marine life Scientists were investigating juvenile fish off the coast of Okinawa when they discovered a plastic bottle floating in the sea. They were surprised to discover that something very unusual lived inside. “(To my surprise) a large live swimming crab… bad luck“The crab was trapped inside the bottle,” Hajime Sato and Yoichi Sakai, who discovered the crab, said in a statement. “The crab was clearly bigger than the mouth of the bottle!” They wondered how the crab got inside. When a…
A study conducted in Poland of women in committed, sexually active relationships found that women who perceived themselves as having lower mate value than their partners showed a stronger desire to sexually satisfy their partners. This higher motivation, in turn, was associated with these women initiating sex more often, performing fellatio, and faking orgasms. The paper is Archives of sexual behavior. Having a stable romantic relationship is beneficial for both men and women. Stable romantic relationships provide emotional security, shared resources, mutual protection, and a trusting environment for raising children. From an evolutionary perspective, long-term bonds may have benefited men…
Scientists have discovered evidence that could change the way doctors think about stroke in general and why standard preventive treatments often fail. A new study suggests that lacunar ischemic stroke is not primarily caused by fatty plaques that build up within the arteries, as many assume. Rather, it appears to be most closely associated with changes in the brain’s blood vessels themselves, particularly dilation and dilation of the arteries. The findings may help explain why commonly prescribed stroke prevention drugs, such as aspirin and other antiplatelet drugs, have limited effectiveness in preventing this type of stroke. Researchers say the results…
Recent evidence suggests that a single dose of the psychedelic compound psilocybin reduces reward-seeking, providing evidence that it has the potential to treat substance use disorders. New research published in European Journal of Neuroscience revealed that this decrease in motivation is associated with increased activity in specific inhibitory brain cells surrounded by a protective net. These findings help explain how psychedelics cause long-lasting changes in the brain circuits that govern decision-making and addiction. Substance use disorders include a pattern of increased drug intake and difficulty resisting urges. The main feature of these symptoms is impulsiveness of choice. This psychological concept…
After a protracted legal battle, President Donald Trump has been given permission to continue erasing the truth about climate change from America’s national parks. advertisement advertisement Yesterday (Thursday, July 2), the U.S. Court of Appeals in Boston temporarily reversed a judge’s order requiring the Trump administration to reinstall dozens of exhibits it had removed from national parks for exposing the country in a “negative light.” This includes factually accurate representations on topics such as climate change and U.S. involvement in the slave trade. President Trump’s mission to take climate change out of national parks Last year, the president signed an…
Could common, over-the-counter anti-inflammatory drugs become a new weapon against drug-resistant tuberculosis? Early findings suggest immunological benefits, but larger trials are needed to determine whether these lead to improved patient outcomes. study: Adjunctive ibuprofen in highly drug-resistant and highly drug-resistant tuberculosis: a phase IIA open-label pilot clinical trial. Image credit: George Martin Studio/Shutterstock.com Adding ibuprofen to standard treatment for highly drug-resistant tuberculosis did not improve clinical outcomes in a pilot trial, although the anti-inflammatory drug showed signs of reducing inflammation, according to a study published today. nature communications. Can ibuprofen improve outcomes in resistant tuberculosis? Tuberculosis (TB) is an airborne…
