Depression more common among women with gynecological disorders

A new study from the University of Southern Denmark reveals that depression is significantly more common among women with gynaecological disorders—both before and after receiving a diagnosis. The study highlights the need for earlier detection and a more integrated approach between somatic and psychiatric care.

Harnessing nature’s carbon engine: Biomass emerges as a pillar of climate mitigation

Bio-based carbon capture offers a 'triple win' for people, planet, and productivity through decentralized systems cutting synthetic fertilizer use by 20-40% and boosting crop yields by 10-25%. Long-term incorporation of biomass into soils via compost and biochar increases soil organic carbon by 10-40%, improving fertility and resilience.

Better predicting the lifespan of clean energy equipment, towards a more efficient design

A new damage-driven lifetime design methodology has been introduced to predict the lifespan of mechanical equipment used in clean-energy systems. The research offers more consistent lifetime predictions than conventional models and provides a framework for designing reliable and climate-conscious infrastructure.

High seas fisheries management falls short of mandates, analysis finds

An analysis published in Environmental Research Letters found that Regional Fisheries Management Organizations (RFMOs) are underperforming and failing to meet their conservation goals. The study graded 16 RFMOs in 10 categories, with an average score of 46 out of 100, indicating a significant gap between performance and mandates.

UTA, TEES open biomanufacturing hub

The University of Texas at Arlington and TEES launched a new biomanufacturing training and research hub in Dallas, providing hands-on training and state-of-the-art lab space. The National Center for Therapeutics Manufacturing satellite campus strengthens North Texas' biotech workforce and expands research opportunities.

Penguins starved to death en masse, study warns, as some populations off South Africa estimated to have fallen 95% in just eight years

Penguin populations off South Africa have declined drastically due to collapsing food supplies, with some species facing an estimated 62,000 breeding individual losses. The study suggests that sardine biomass has fallen below a quarter of its peak levels in 17 years, posing a significant threat to the long-term survival of these birds.

SCAI responds to 2025 Interventional Cardiology Match results and affirms commitment to strengthening the workforce pipeline

The Society for Cardiovascular Angiography and Interventions (SCAI) reviewed the 2025 Interventional Cardiology Fellowship Match results, noting that nearly all applicants successfully matched but 71 positions remained unfilled. SCAI attributes this to a lack of trainees in the pipeline, citing factors like radiation exposure and burno...

Avoiding marine collisions with SMART-SEA

Researchers at Texas A&M University have created a system called SMART-SEA to combat marine collisions by providing seafarers with real-time guidance on how and when to maneuver their vessel. The system combines raw radar imaging data with advanced machine learning to identify stationary objects and recommend safe actions.

Internet use may protect caregivers against loneliness

A study by NYU Rory Meyers College of Nursing found that older, unpaid caregivers who used the internet more often felt less lonely and coped better with stress. The researchers analyzed data from over 3,957 participants ages 65 and older, and discovered a buffering effect: internet use reduced loneliness in caregivers with health issues.
