Barbie could dampen a young girl's career dreams

A study published in Springer's journal Sex Roles found that playing with Barbie dolls can restrict girls' career aspirations compared to playing with more neutral toys. The researchers suggest that the doll's unrealistic appearance and objectification may contribute to this effect.

New terms used for trainee doctors stump nurses and patients

A survey of nurses and patients in a UK hospital found that many struggle to identify qualified doctors from their name badges, which use new terminology introduced since 2009. The researchers call for a national review of the current system, suggesting simpler terms that include 'doctor,' 'senior,' and 'junior' to improve identification.

With flip of wrist, interventional radiologists treat uterine fibroids

Researchers find that a novel approach to accessing the uterus, using the wrist instead of the groin artery, can significantly reduce pain and trauma for women undergoing uterine fibroid embolization. The transradial access technique allows patients to walk immediately after treatment, improving their experience.

An inventive new way to profile immune cells in blood

A new technique uses DNA methylation signatures to detect immune cell types in blood samples, showing high accuracy compared to existing methods. The approach counts specific chemical alterations that distinguish between cell types, enabling researchers to understand the unique signature of each cell type.

Patients' stories used to improve care on wards

Researchers at University of Oxford are using patient stories to stimulate change in healthcare. They've found that small changes, such as clocks on the wall for intensive care patients or more comfortable pillows, can greatly improve patient experience. This approach brings compassion and dignity back to the fore.

Atypical development in the siblings of children with autism is detectable at 12 months

Researchers detected atypical development in nearly half of the younger siblings of children with autism by 12 months. The study found that many of these children showed delays in social, communication, cognitive, or motor development, particularly in social-communication domains.

OU study suggests non-uniform climate warming global

A recent University of Oklahoma study suggests that non-uniform climate warming affects global regions differently, impacting ecosystem functions such as food production and carbon sequestration. The effects of non-uniform warming on terrestrial ecosystems are a key challenge in carbon cycle research and future predictions.

Darwin: It's not all sexual (selection)

A team of researchers found that 71% of surveyed birds had female song, contradicting the long-held assumption that bird song is an exclusively male trait resulting from sexual selection. The study suggests that social selection may have played a role in the evolution of bird song, with both males and females competing for resources.

Researchers identify key enzyme found in bacteria responsible for heart valve disease

Researchers at Virginia Commonwealth University and MIT have identified a key enzyme necessary for a disease-causing bacterium to survive, which may lead to the development of new antibiotics. The study found that eliminating this enzyme or its manganese-attachment protein prevents the bacterium from causing heart valve disease.

Long-lasting device protects against HIV and pregnancy

A Northwestern University-designed intravaginal ring provides both antiretroviral drug and contraceptive protection for months, addressing a significant need in women's reproductive health. The device, known as the tenofovir levonorgestrel IVR, has been engineered to deliver controlled doses of these medications over an extended period.

Banana plant fights off crop's invisible nemesis: Roundworms

The Yangambi km5 banana variety produces toxic metabolites that kill the nematode Radopholus similis, a major roundworm pest. This discovery could lead to the development of edible and pest-resistant banana varieties, as well as new pesticides against nematodes.

Are bilingual kids more open-minded?

New research from Concordia University suggests that bilingual children, like monolingual peers, prefer interactions with those speaking their mother tongue with a native accent. This bias may be related to children's preference for familiarity, according to the study.

Plumes in the sleeping avian brain

Researchers discovered 3D plumes of brain activity propagating through the avian brain, differing from mammalian slow-wave-sleep patterns. This finding suggests alternative computational properties and challenges the layered organization assumption.

Your face says it all? Not so fast

A new study disputes the idea that humans experience six basic emotions universally, citing context-dependent expression recognition. Researchers found that facial expressions and vocalizations were not consistently labeled with emotion words across cultures, suggesting cultural categories may be at play.

Going viral to target tumors

Researchers found that injecting a virus directly into one melanoma tumor can induce a potent anti-tumor immune response, destroying both infected and non-infected tumors. This combination therapy overcomes the limitations of oncolytic virotherapy and checkpoint blockade.

Sulphur haunts the ghost wreck

Researchers found relatively low iron amounts and minimal sulphur compounds in the Ghost wreck, suggesting it might not face the same preservation issues as the Vasa. Three studied ships, including the Crown, display more aggressive sulphur compounds and higher iron concentrations.

New guidance for preventative action against diabetes

A team of University of Leicester academics helped develop NICE guidelines to prevent diabetes in black, Asian and minority ethnic groups. The new guidance emphasizes the importance of body mass index as a signal for preventive action, aiming to reduce the incidence of diabetes by increasing physical activity and healthy diet.

Adolescent relationship violence has mental health implications for victims, perpetrators

A new study by Bowling Green State University researchers links adolescent relationship violence to increased symptoms of depression among both victims and perpetrators. The study found that high levels of discord within intimate relationships have a similar negative effect on the emotional well-being of young men and women.
