Penn study links better 'good cholesterol' function with lower risk of later heart disease

A large prospective study found that individuals with higher HDL function have a lower risk of developing coronary heart disease. Researchers from the University of Pennsylvania analyzed data from over 25,000 participants and discovered a strong correlation between HDL function and reduced heart disease events.

Severe ozone depletion avoided

A new study confirms the Montreal Protocol has effectively protected the ozone layer from severe depletion, with atmospheric concentrations of harmful substances declining since their peak in 1993. The researchers used a state-of-the-art model to investigate the impact of the treaty and found that without it, the Arctic ozone hole woul...

Supernovas help 'clean' galaxies

Recent research found that supernovas work hand-in-hand with supermassive black holes to sweep out gas, interrupting star formation in galaxies. The partnership of these celestial events may help understand why massive galaxies stopped forming stars billions of years ago.

ER doctors stress need for good communications with police

ER physicians emphasize the importance of developing strategies to optimize communications between police and ED workers due to differing perspectives on patient privacy and investigation needs. They suggest attempting to obtain patient consent before disclosing information and using limited disclosure when necessary.

Monitoring magnetospheres

A Queen's University PhD student is conducting the first systematic population study of magnetosphere-host stars, finding that plasma density within all such magnetospheres is far lower than predicted. This suggests that plasma might be escaping gradually, maintaining magnetospheres in an essentially steady state.

Ovarian cancer-specific markers set the stage for early diagnosis, personalized treatments

Researchers at University of California, San Diego, have identified six mRNA isoforms that distinguish ovarian cancer cells from normal cells, offering potential for early diagnosis and targeted therapies. The study's findings may also lead to new therapeutic targets and more effective treatment options.

Study suggests new way of preventing diabetes-associated blindness

Researchers at Johns Hopkins University and the University of Maryland have discovered a new way to treat diabetic retinopathy by blocking two growth proteins, VEGF and angiopoietin-like 4. This could prevent many cases of proliferative diabetic retinopathy, which is the most common cause of vision loss in working-age adults in the US.

In study, new swab reveals one-third of babies with severe diarrhea had undiagnosed, treatable infection

A new 'flocked swab' tool improved diagnosis and treatment of deadly childhood diarrheal diseases, saving lives by pinpointing treatable pathogens. The innovative test-and-treat strategy led to significant health improvements, including reduced diarrhea recurrence and increased growth in children.

Climate engineering may save coral reefs, study shows

A new study suggests that geoengineering techniques, such as Solar Radiation Management, can reduce the risk of global severe bleaching and degradation of coral reefs. The research found that even under ambitious CO2 reduction scenarios, widespread coral bleaching will occur by the middle of this century.

Complex signaling between blood and stem cells controls regeneration in fly gut

Researchers at the Buck Institute discovered that macrophage-like hemocytes play a crucial role in regulating stem cell activity in the fly gut. This complex signaling interaction helps control intestinal regeneration after damage, but goes awry with age, potentially contributing to human diseases like IBS and colorectal cancer.

Frailer older patients at higher risk of readmission or death after discharge from hospital

A study published in the Canadian Medical Association Journal found that frailer older patients are at a higher risk of readmission to hospital or death within 30 days after discharge. The researchers assessed the use of the Clinical Frailty Scale, which can help identify patients at high risk of poor outcomes.
