( Metformin during pregnancy affects the brain development in offspring mice, study finds
Mar 20th 2024, 16:05

With the rise in gestational diabetes and metabolic disorders during pregnancy, metformin is also being prescribed more frequently. Although it is known that the oral antidiabetic agent can cross the placental barrier, the impacts on the brain development of the child are largely unknown. Researchers have now been able to demonstrate in a mouse model that although metformin has positive effects in pregnant animals, it does not in the offspring.

( Perceived gender discrimination linked to decline in wellbeing for older women
Mar 20th 2024, 16:04

A study of more than 3,000 middle-aged and older women living in England showed that those who believed they had encountered gender discrimination were more likely to report declines in wellbeing over time.

( Fear may lead women and men to make different decisions when choosing short-VS-long-term rewards
Mar 20th 2024, 16:04

Fear may affect women's decisions in choosing immediate rewards versus larger delayed ones, while men's decisions appear unaffected by emotion, according to a new study.

( Social bonding gets people on the same wavelength
Mar 20th 2024, 12:25

When small hierarchical groups bond, neural activity between leaders and followers aligns, promoting quicker and more frequent communication, according to a new study.

( Low social status increases risk of health problems from alcohol problems
Mar 20th 2024, 12:25

Men and women with lower income or education levels are more likely to develop medical conditions related to alcohol abuse compared to similar individuals with a higher socioeconomic status, according to a new study.

( Craving snacks after a meal? It might be food-seeking neurons, not an overactive appetite
Mar 20th 2024, 12:25

A new study has shown that food-seeking cells exist in a part of a mouse's brain usually associated with panic -- but not with feeding. Activating a selective cluster of these cells kicked mice into 'hot pursuit' of live and non-prey food, and showed a craving for fatty foods intense enough that the mice endured foot shocks to get them, something full mice normally would not do. If true in humans, who also carry these cells, the findings could help address the circuit that can circumvent the normal hunger pressures of 'how, what and when to eat.'

( Powerful new AI can predict people's attitudes to vaccines
Mar 20th 2024, 12:24

A powerful new tool in artificial intelligence is able to predict whether someone is willing to be vaccinated against COVID-19.

( Biomarkers of the middle-aged brain predict cognitive health in old age
Mar 19th 2024, 12:29

The middle-aged brain could provide a window into future cognitive health. A team reviewed evidence from human and animal studies suggesting that middle age -- commonly considered as the period between 40 and 60 or 65 years of age -- marks a shift in brain aging. They argue that more research should be dedicated to middle age, a period of life that is historically understudied.

( New technique helps AI tell when humans are lying
Mar 18th 2024, 14:23

Researchers have developed a new training tool to help artificial intelligence (AI) programs better account for the fact that humans don't always tell the truth when providing personal information. The new tool was developed for use in contexts when humans have an economic incentive to lie, such as applying for a mortgage or trying to lower their insurance premiums.

( Laws that punish drug use during pregnancy likely lead to worse health outcomes for families, study finds
Mar 18th 2024, 14:23

Contrary to some claims, laws that criminalize or otherwise punish drug use during pregnancy are more likely to worsen rather than improve health outcomes. The study is the first to systematically review the literature on punitive prenatal drug laws -- an increasingly common state policy strategy for addressing rising rates of prenatal drug use.

( Less social with age
Mar 15th 2024, 16:10

Scientists tested several hypotheses on the drivers of social aging in free-living Assamese macaques in Thailand. The researchers collected data on the social behavior of females for eight years and found that the size of their social networks decreases with increasing age. The females continued to interact with their close social partners, but gradually withdrew from social interactions altogether. The results contribute to the understanding of the evolutionary origins of social aging.

( Abnormal brain structure identified in children with developmental language problems
Mar 15th 2024, 16:09

A rigorous analysis of numerous studies concludes that a part of the brain traditionally associated with movement is abnormal in children with developmental language impairments. The discovery has the potential to improve both the diagnosis and treatment of the language difficulties.

( New study reveals breakthrough in understanding brain stimulation therapies
Mar 15th 2024, 16:09

Researchers show that non-invasive brain stimulation can change a specific brain mechanism that is directly related to human behavior.
