Severity of road accidents and the injuries sustained vary according to sex of the driver and passengers

A new study published in Heliyon analyzed the characteristics of drivers and passengers involved in traffic accidents in Spain between 2014 and 2020. The results show that the risk of death or serious injury among passengers is lower when the driver is female, but higher for female occupants. This could be attributed to biological and ...

To make fluid flow in one direction down a pipe, it helps to be a shark

A team of researchers from the University of Washington has developed a flexible pipe with an interior helical structure inspired by shark intestines, which can keep fluid flowing in one direction without flaps. The design rivaled and exceeded Tesla valves, a one-way fluid flow device invented over a century ago.

How special is the Milky Way Galaxy?

The SAGA Survey has found that the Milky Way Galaxy appears to be an outlier in terms of its satellite galaxies, having acquired only two large satellites recently compared to other systems. The survey also explores the mechanisms that would stop star formation in these small galaxies, finding that environmental factors play a role.

Federal broadband subsidies boosted rural internet, but service faded once funding ended, UCSB researchers find

A federal broadband subsidy program boosted high-speed internet to remote and rural areas, but once funding ended, much of the service faded. The study found that only about half of the sampled addresses certified as served were actually being provided by ISPs, highlighting the need for independent evaluations.

Self-esteem boosts sexual well-being – and vice versa

A long-term study of over 11,000 German adults found that people with higher self-esteem tend to have more satisfying sexual relationships and that the two factors influence each other. The study showed significant correlations over time, with changes in sexual satisfaction leading to changes in self-esteem.
