Singing in the brain: Songbirds sing like humans

A recent study published in the Journal of Neuroscience found that songbirds' vocal muscles can change their function to produce different sound parameters, similar to a trained opera singer. The research, led by Samuel Sober, shows that the bird's brain directs complex changes in muscle combinations to create complex songs.

Racial disparity in premature births contributes significantly to infant mortality problem

A new study found a significant racial disparity in premature births among black women, which may explain much of the racial disparity in infant mortality. The study suggests that public health efforts should focus on access to prenatal care and preventive measures for high-risk black women.

Brain receptor regulates fat burning in cells

Scientists at Gladstone Institutes discovered a novel regulator of body weight: the P75 neurotrophin receptor. Lowering levels of p75 NTR protected mice from developing obesity, diabetes, and fatty liver disease on a high-fat diet. The receptor plays a key role in regulating metabolic processes that control body weight.

Standardized approach makes outpatient thyroid surgery safe for even the elderly, super-elderly

A recent study published in the journal Surgery found that outpatient thyroid surgery is safe for even the elderly and super-elderly, thanks to a standardized treatment approach. The study showed that while older patients have more comorbid conditions, complication rates held steady at 5-6 percent across all groups.

What should be the role of computer games in education?

A new study discourages a sweeping transformation of conventional education to replace traditional curricula with game-based instruction. Instead, researchers recommend adding promising features to games, such as explanatory feedback and pregame activities, to enhance learning outcomes. Game features that improve student performance in...

Traumatic brain injury induces mental impairments using mechanisms linked with Alzheimer's

A new study finds that traumatic brain injury induces mental impairments using mechanisms linked with Alzheimer's disease, specifically the toxic form of tau protein. The research suggests that TBI may share a common mechanism with neurodegenerative diseases, increasing the risk for dementia and other neurological disorders.

Greenland ice sheet melts more when it's cloudy

Clouds play a significant role in the melting of the Greenland ice sheet, with clouds enhancing meltwater runoff by a third. The study highlights the need for accurate cloud representations in climate models to estimate the amount of meltwater and mitigate global sea level rise.

Real-time fishery management significantly reduces bycatch

A new study finds that dynamic closures can reduce bycatch up to three times more efficiently than static measures, while minimizing economic impact on fishermen. By managing at finer scales, managers can zero in on transitory hotspots and reduce the need for large-scale closures.

Poison warmed over

Researchers found that warmer temperatures reduce desert woodrats' ability to eat their normal diet of toxic creosote bushes. This could lead to animals changing their diets, relocating to cooler habitats or going extinct in local areas.

Brain monitoring takes a leap out of the lab

A wearable, 64-channel brain monitoring system has been developed, providing a better fit for real-world applications. The system comprises a dry-electrode wearable EEG headset and sophisticated software for data interpretation, with a wide range of applications in research, neuro-feedback, and clinical diagnostics.

Use small plates to lose weight

A recent study found that smaller plates can lead to a 30% reduction in food consumption on average, particularly when diners are self-serving their portions. The research also discovered that consumers who are unaware they are being monitored are more likely to benefit from the use of smaller plates.

Grazing towards sustainability

The Global Farm Platform conference presents research findings on sustainable livestock systems, showing that traditional measures of dairy cow performance are oversimplified. Knowledge exchange between farmers and researchers reveals that robust cows can be more economically viable due to their good health, fertility, and ability to t...

Pre-pregnancy potato consumption may be linked to gestational diabetes risk

A National Institutes of Health study found that women who eat more potatoes before pregnancy may have higher rates of gestational diabetes compared to those who consume fewer potatoes. Substituting potatoes with other vegetables, legumes or whole grains may help lower gestational diabetes risk, according to the researchers.

SCAI releases expert consensus for cardio-oncology patients treated in cardiac catheterization labs

The Society for Cardiovascular Angiography and Interventions has released a consensus statement providing guidance for treating patients with concomitant cardiovascular disease and cancer. The document aims to increase the competency of cardiovascular professionals in caring for cancer patients, who are expected to increase to 20 milli...
