New study: How to save a seabird

Alaska's longline fisheries have reduced seabird bycatch by 77-90% since adopting streamer lines in 2002, saving thousands of birds per year. However, recent years have seen an increase in bycatch rates, particularly for albatrosses and northern fulmars.

UBC researchers discover how blood vessels protect the brain during inflammation

Researchers at UBC have discovered a protein called podocalyxin that plays a key role in protecting the brain from harmful blood components during inflammation. The study's findings could lead to the development of new treatments for stroke, epilepsy, and multiple sclerosis by inducing temporary opening of the blood-brain barrier.

A volcanic binge and its frosty hangover

Researchers from Heidelberg University discovered a large igneous province that could have triggered the Gaskiers glaciation approximately 580 million years ago. The basaltic eruptions covered an area of over 1,000 kilometers and may have led to short-term global warming before causing long-term climate effects.

New insight into river flows and sediment transport under ice cover

A new study from the University of Eastern Finland explores the effects of ice cover on river channels and sediment transport. The research found that ice cover influences flow structures and increases sediment deposition in 'whirlpools' with low flow velocity. This discovery highlights the importance of considering seasonal changes in...

The new exercise trend that's made for everyone

Researchers propose incorporating short high-intensity incidental physical activity (HIIPA) into daily routines to improve health. HIIPA involves brief bursts of high-intensity exercise, such as walking uphill or carrying groceries, which can be done in just a few minutes a day and offer significant health benefits.
