Moon mission delays could increase risks from solar storms

Scientists have discovered a clear pattern in extreme space weather events, making it possible to predict when they will occur. The findings suggest that Moon missions may be delayed to avoid the most intense periods of solar activity, which can pose risks to astronauts and satellites.

A peptide that allows cannabis-derived drugs to relieve pain without side effects

A team of scientists from Pompeu Fabra University has developed a peptide that allows delta-9-tetrahydrocannabinol (THC) to fight pain in mice without cognitive side effects. The peptide, which interrupts the interaction between THC and serotonin receptors, improves memory capacity while providing analgesia.

Hubble tracks down fast radio bursts to galaxies' spiral arms

Astronomers use Hubble to pin five FRBs to host galaxies and identify their origins as young magnetar outbursts. The study provides new insights into the nature of these powerful events, which generate energy equivalent to the Sun's in a year.

Study finds gender pay gap in large government agency

A study by the University of Georgia found a persistent gender pay gap at the US Department of Health and Human Services, with women earning 9.2% less than men in 2018. The research suggests that differences in promotion within higher pay grades may be contributing to the gap.

Red meat intake, poor education linked to colorectal cancer

A new study found that higher red meat intake and lower educational attainment are associated with an increased risk of colorectal cancer in people under 50. The research also linked lower fiber and folate intake to a stronger link between rectal cancer and early-onset cases.

We know the cost of free choice and locality - in physics and not only

Researchers explore the relationship between free choice, locality, and causality using Bell's inequalities. They find that reality breaks these inequalities, prompting questions about local realism and experimenters' choices.

Out of thick air: Transforming CO2 into light-emitting carbon

A team of researchers at the University of Ottawa has developed a new pathway to transform CO2 gas into solid carbon forms that emit light, creating a low-energy alternative. The breakthrough uses visible light to initiate dissociation in carbon dioxide molecules on a nanostructured silver surface.

The impact of real-time feedback in employee reviews

New research reveals that real-time feedback from supervisors tends to be more critical, while peers do not adopt tit-for-tat strategies. Positive feedback also has a stronger effect on future ratings than negative feedback, with men rating women higher than themselves and women rating both equally.

Forensic memory detection tests less effective in older adults

New research by University of Kent found that EEG-based forensic memory detection tests have limited validity in older adults due to changes in recognition-related brain activity with aging. The study tested 30 young and 30 older adults using concealed information tests, finding only strong EEG responses in the younger group.
