Chronic illness causes less harm when carnivores cooperate

A study by Penn State researchers found that wolves in packs with at least five healthy members have a similar death rate to their companions when infected with mange. This suggests that social living can help individuals cope with various chronic conditions by providing supportive care and resources.

Studying dynamics of ion channels

Scientists have developed a powerful tool to investigate ion channel selectivity using infrared spectroscopy and molecular dynamic-based simulations. This approach allows for the detection of subtle conformational changes in large membrane proteins, such as potassium channels, at atomic resolution.

UM-based cooperative research institute receives $125 million award, renewed agreement

CIMAS, a 10-member research consortium based at the University of Miami Rosenstiel School, has received a $125 million award from NOAA to fund its activities over the next five years. The renewed partnership will focus on improving hurricane forecasting, ecosystem-based ocean management, and climate prediction.

Not all women with dense breasts need more imaging; ACP advises 'smarter' cancer screening

A study published in Annals of Internal Medicine suggests that women with extremely dense breasts do not necessarily need additional imaging after a normal mammogram. However, those with high-risk dense breasts should discuss supplemental screening strategies with their doctors. The American College of Physicians advises 'smarter' canc...

Cooling children after cardiac arrest provides no significant benefit

A recent study published in the New England Journal of Medicine found that cooling children after cardiac arrest does not provide any significant survival-with-quality-of-life benefits. The study, which included nearly 300 participants, compared two groups: one cooled to a lower body temperature and the other maintained normal temperat...

Organic nanoparticles, more lethal to tumors

Researchers have found that carbon-based nanoparticles can produce low-energy electrons through plasmon excitation, making them more lethal to tumors and potentially inducing focused destruction of cancer cells. This breakthrough could lead to the development of novel types of sensitizers for proton radiotherapy.

Brain scans show birds of a feather do flock together

Researchers at Virginia Tech Carilion Research Institute found that brain signals predict the likelihood of conforming to others' choices, with individuals more likely to follow risks if they like taking risks and safer options if cautious. The study sheds light on how social support systems can encourage healthy choices.

Exposure of US population to extreme heat could quadruple by mid-century

A new study projects that US residents' exposure to extreme heat could increase four- to six-fold by mid-century, driven by both a warming climate and a growing population. The research found that the average annual exposure to extreme heat in the US during this period is expected to be between 10 and 14 billion person-days.

Adolescents, drugs and dancing

A new NYU study found that rave attendees are more likely to use various illicit drugs, including ketamine and GHB, with rates 2-6 times higher than non-attendees. The study also revealed that 7.7% of students reported attending raves at least monthly.

Lung cell phenotype reverts when seeded onto decellularized lung matrix

Researchers found that type II lung epithelial cells differentiated into mesenchymal cells instead of type I cells when seeded onto decellularized lung matrix. This study highlights the importance of factors like cell populations, growth medium, and stimuli in achieving physiologically appropriate environments for lung tissue growth.

Team science is better science

A groundbreaking report from the National Research Council concludes that team science is increasingly used in scientific research, enhancing innovation and impact. However, resolving the challenges of effective team science requires attention to assembling the right people, training and development, and team leadership.

University of Montana research finds evidence of non-adaptive evolution within cicadas

Researchers at the University of Montana have discovered evidence of non-adaptive evolution within cicadas, where a single bacterium has split into dozens of species, complicating the insect's symbiotic relationship. This complexity may be detrimental to the cicada's survival, as it relies on the bacteria for essential nutrients.

Gender-science stereotypes persist across the world

A Northwestern University study reveals that gender-science stereotypes are prevalent worldwide, with Scandinavian countries and the Netherlands showing strong associations between science and men. However, nations with more female scientists exhibit weaker stereotypes, suggesting exposure to women in college may change beliefs.

Designing better medical implants

MIT researchers found that larger spherical devices are better able to maintain their function and avoid scar-tissue buildup, outperforming smaller ones in tests on diabetic mice and nonhuman primates. This discovery could lead to the development of long-term implants for diabetes treatment and other diseases.
