Geothermal heat contributes to Greenland ice melt

A recent study by University of Montana researcher Jesse Johnson reveals that geothermal heat enhances rapid ice flow and subglacial melting in northern Greenland. The research, published in Nature Geoscience, identifies a west-to-east zone with anomalously high heat that drives widespread melting and rapid ice flow.

A better fix for torn ACLs

Researchers at the University of Missouri have developed a model showing a newer surgical technique results in a stronger, more natural ACL repair. The new suspensory fixation method reduces cell and tissue damage to the graft, allowing for full functional healing.

Can urban gardeners benefit ecosystems while keeping food traditions alive?

A study found that urban gardens in Chicago's African American, Chinese-origin, and Mexican-origin communities provide important ecosystem services. The researchers identified non-native crops and synthetic fertilizers as potential issues, but also noted the cultural significance of gardening for food security and community connection.

Indiana University-led researchers identify objective predictors of suicidality in women

Researchers at Indiana University have identified blood-based biomarkers and developed questionnaire-based apps that can help clinicians identify female patients at greatest risk of suicidal ideation or behavior. The study found that these tools were able to predict future instances of suicidal thoughts with high accuracy, suggesting p...

Screening for COPD not recommended

The US Preventive Services Task Force recommends against routine screening for COPD in asymptomatic adults due to lack of evidence on benefits and potential harms. Screening may divert resources from other preventive services, such as smoking cessation.

Study shows certain gastrointestinal tumors associated with higher mortality

Researchers at University of California, San Diego School of Medicine found that certain groups of gastrointestinal stromal tumors result in a much higher mortality rate than expected. The study analyzed data from 378 patients with malignant GISTs and discovered significant variability in size and malignant behavior.

Cost-effective production of hydrogen from natural resources

Researchers at Ulsan National Institute of Science and Technology (UNIST) have developed a cost-effective method for producing high-purity silicon nanosheets, which are essential for the mass production of hydrogen. The new technique uses natural clay and salt to synthesize these nanosheets, significantly reducing production costs.

Researchers show corals struggle to grow under multiple stressors

A new study found that corals preconditioned to high CO2 levels before increased temperatures showed 44% lower growth rates compared to unconditioned corals. This suggests that elevated CO2 worsens coral response to thermal stress, potentially exacerbating climate change impacts on coral reefs.

Promising new method inhibits TB-causing bacteria

Scientists have discovered a new way to inhibit the growth of Mycobacterium tuberculosis by using modified cholesterol as an energy source. This breakthrough holds promise for the development of new treatments for tuberculosis, a highly infectious lung disease that kills one person every 21 seconds.

Risk allele for side effects induced by Clozapine identified

A significant association has been found between HLA-B*59:01 and Clozapine-induced agranulocytosis and granulocytopenia, suggesting the allele may serve as a marker for prioritizing patients at low risk of developing these severe side effects. Further analysis is needed to clarify the mechanism behind this association.
