Boys are good at math, girls not so much? A study has analyzed the social mechanisms that contribute to the gender gap in math confidence. While peer comparisons seem to play a crucial role for boys, girls' subjective evaluations are more likely to be based on objective performance. Read more ›

People who eat a healthy, sustainable diet may substantially lower their risk of premature death in addition to their environmental impact, according to a new study. This large study directly evaluates the impacts of adherence to recommendations in the landmark 2019 EAT-Lancet report. The researchers have named the dietary pattern outlined in the report -- which emphasizes a variety of minimally processed plant foods but allows for modest consumption of... Read more ›

Academics are often accused of 'splitting hairs', but a team has now devised a machine to do just that. We all have a bad hair day from time to time, and split ends are a common problem. However, the science behind this kind of hair damage is poorly understood, which is why scientists are investigating this knotty problem. Read more ›

Astrophysicists calculate the likelihood that Earth was exposed to cold, harsh interstellar clouds, a phenomenon not previously considered in geologic climate models. Read more ›

People with an optimistic outlook on the future are less likely to be severe procrastinators, according to new research. While procrastinators often admonish themselves for their 'bad habit,' it turns out that their worries for the future are more to blame. Through a survey of nearly 300 young people, researchers found that those who had a positive view about their stress levels decreasing in the future, compared to the past... Read more ›

Having explored how the heart is formed in utero, a researcher is reporting how cells and molecules act during that early formation and what might cause the heart disease called left ventricular non-compaction or spongy heart, for which patients often require heart transplants. Read more ›

After women go through menopause, their risk of heart disease increases dramatically. Researchers studied whether beetroot juice, which is rich in nitrate, can improve how blood vessels function. The results showed that daily consumption of beetroot juice by postmenopausal women may improve blood vessel function enough to reduce future heart disease risk. Read more ›

Immune activation in a pregnant woman can occur in response to metabolic diseases like obesity, infections in pregnancy, exposure to pollution and environmental toxins, or even stress and can have negative effects on fetal brain immune cells (microglia). It's not possible to monitor microglia within the fetal brain, but new research indicates that macrophages in the placenta can act as an indicator of these cells' health. Read more ›

An international research team has discovered the oldest known marine plant using a novel genetic clock. This 1400-year-old seagrass clone from the Baltic Sea dates back to the Migration Period. The research project is a significant step towards better understanding and protecting marine ecosystems. Read more ›

When scientists transplanted the gut microbes of aged mice into young 'germ-free' mice -- raised to have no gut microbes of their own -- the recipient mice experienced an increase in inflammation that parallels inflammatory processes associated with aging in humans. Young germ-free mice transplanted with microbes from other young mice had no such increase. Read more ›

A clinical trial on a two-drug therapy for methamphetamine use disorder reduced use of the highly addictive drug for up to 12 weeks after initiation of treatment. Participants in the ADAPT-2 clinical trial who received a combination of injectable naltrexone plus extended-release oral bupropion (NTX+BUPN) had a 27% increase in methamphetamine-negative urine tests, indicating reduced usage. By contrast, the placebo group had an 11% increase in negative tests. To date... Read more ›

Efforts to tackle false information through fact-checking or media literacy initiatives increases the public's skepticism toward 'fake news'. However, they also breed distrust in genuine, fact-based news sources, a new study using online survey experiments in the US, Poland and Hong Kong shows. Read more ›

How do pathogens invade the lungs? Using human lung microtissues, a team has uncovered the strategy used by a dangerous pathogen. The bacterium targets specific lung cells and has developed a sophisticated strategy to break through the lungs' line of defense. Read more ›

Scientists have improved a gene-editing technology that is now capable of inserting or substituting entire genes in the genome in human cells efficiently enough to be potentially useful for therapeutic applications. The advance could one day help researchers develop a single gene therapy for diseases such as cystic fibrosis that are caused by one of hundreds or thousands of different mutations in a gene. Using this new approach, they would... Read more ›

Astronomers have deciphered the formation history of young star clusters, some of which we can see with the naked eye at night. The team reports that most nearby young star clusters belong to only three families, which originate from very massive star-forming regions. This research also provides new insights into the effects of supernovae (violent explosions at the end of the life of very massive stars) on the formation of... Read more ›

An international team of planetary scientists has detected patches of water frost sitting atop the Tharsis volcanoes on Mars, which are not only the tallest volcanic mountains on the Red Planet but in the entire solar system. Read more ›

Wild African elephants address each other with name-like calls, a rare ability among nonhuman animals, according to a new study. Researchers used machine learning to confirm that elephant calls contained a name-like component identifying the intended recipient, a behavior they suspected based on observation. The study suggests elephants do not imitate the receiver's call to address one another but instead use arbitrary vocal labels like humans. Read more ›

By super cooling a molecule on the surface of brain cells down to about minus 180 degrees Celsius -- nearly twice as cold as the coldest places in Antarctica -- scientists say they have determined how a widely-used epilepsy drug works to dampen the excitability of brain cells and help to control, although not cure, seizures.
