Genetic study explores how human pregnancy is unique

A new genetic study reveals hundreds of genes that evolved to be turned on or off in the human uterus during early pregnancy, shedding light on what makes human pregnancy uniquely human. These genes are involved in cell-to-cell communication, immune response regulation, and placental invasion, highlighting the importance of evolutionar...

Testing troubles

A study by University of New Mexico researchers found that 65% of women with a normal prior co-test had undergone re-screening within three years, far more often than recommended. Meanwhile, some women were not re-tested for over five years after a negative co-test or cytology alone, increasing their risk for poor outcomes.

Wind farm noise may not be more disruptive to sleep than other sources

A Flinders University study found that residents living near wind farms reported similar levels of sleep disruptions as those in quiet rural areas. Only a small percentage attributed their sleep disturbance to wind farm noise, which was comparable to rates from road traffic and other sources.

Tree-dwelling mammals endured after asteroid strike destroyed forests

A new study suggests that tree-dwelling mammals, including primates and their ancestors, survived the asteroid strike that devastated Earth's forests 66 million years ago. The research found that ground-dwelling mammals had a selective advantage over arboreal counterparts, but some tree-dwellers managed to survive.

Understanding variations in Salmonella virulence

Researchers from the University of Seville discovered that a single amino acid mutation in Salmonella enzymes enables them to modify more proteins in infected cells, leading to increased virulence. This finding has significant implications for developing inhibitors as alternative antibacterial treatments.

Automatic entry into career advancing competitions could help women, study suggests

A recent study by researchers from the University of Toronto and UCLA Anderson School of Management found that automatic entry into competitive processes can reduce gender disparities in decision-making. In three cash-for-task experiments with over 1500 participants, women were shown to be as competitive as men when given the option to...

Power walk

Researchers developed a powered exoskeleton that provides extra energy for walking, reducing the strain on amputee muscles. The device was tested by six individuals with above-knee amputations, showing a 15.6% improvement in metabolic rate and allowing users to walk for extended periods.

Eliminating uranium from the food chain: Are fungi the key?

A new study suggests that fungi can alter the uptake of uranium by plants, potentially reducing its spread through the food chain. The research found that the presence of fungi decreased the concentration of uranium in plant tissues and reduced its translocation throughout the plant.

New study sheds light on molecular motion

Scientists have developed a synthetic fibre that guides molecular movement fueled by light over long distances, paving the way for new sustainable energy sources and applications in medicine and chemical tasks. The system emulates cellular fibres, allowing for controlled transport of molecules using light as energy.
