Oxford, Harvard scientists lead data-sharing effort

Researchers at University of Oxford and Harvard Stem Cell Institute have developed a common standard to describe and integrate large datasets from various fields, enabling better coordination of findings. The ISA Commons platform allows small research groups to store laboratory data without dedicated bioinformatics support.

What do killer whales eat in the Arctic?

Researchers combined scientific observations with Canadian Inuit traditional knowledge to determine Arctic killer whale behaviour and diet. Arctic killer whales primarily eat marine mammals, such as seals and bowhead whales, but little is known about their prey preference.

Sexual healing? Not likely

Research by Monash University reveals that producing high-quality sperm comes with significant health costs for males. The study found a negative correlation between sperm quality and immune function, suggesting males invest energy strategically to produce better sperm.

Differences in systolic blood pressure between the left and right arm could indicate vascular disease and increased likelihood of death

A systematic review and meta-analysis found that a difference of 15mm Hg or more between arms is associated with increased risk of peripheral vascular disease, pre-existing cerebrovascular disease, cardiovascular mortality, and all-cause mortality. Measuring blood pressure in both arms should be part of routine care to identify patient...

Genetic regulation of metabolomic biomarkers – paths to cardiovascular diseases and type 2 diabetes

Researchers identified 31 genetic regions associated with circulating metabolites, including biomarkers for cardiovascular disease and type 2 diabetes. The study provides new insights into the biological processes leading to common diseases, suggesting that detailed data on multiple metabolites can help elucidate these processes.

Ultrasound male contraceptive, overlooked for decades, confirmed to work

Researchers have confirmed that therapeutic ultrasound can be used as a male contraceptive, providing up to 2.5 months of protection in rats with two 15-minute sessions. The method was initially overlooked for decades due to concerns over its effectiveness, but new evidence suggests it may offer an alternative to existing options.

2-arm blood pressure check indicator for risk from heart disease or death

Researchers at Peninsula College of Medicine and Dentistry found that differences in systolic blood pressure between arms are associated with increased risk of vascular disease and mortality. A difference of 10mm Hg or more is linked to an increased risk of peripheral vascular disease, pre-existing cerebrovascular disease, and mortality.
