Old X-rays, new vision: A nano-focused X-ray laser

Scientists from Osaka University have reduced X-ray free-electron laser beam diameter to 6 nanometers, enabling precise imaging of single virus particles and ultrafast chemical processes. This advancement improves the accuracy of measurements closer to the atomic level than previously possible.

Host cell fusion in bacteria infection alarms immune system, causing host cell destruction

The study reveals that Burkholderia pseudomallei infection sets off a series of events that provoke the host's immune system, causing infected cells to self-destruct. The researchers found that abnormal cell fusion stimulates the type 1 interferon signaling pathway, leading to autophagy and cell death.

Men and younger adults less active in lockdown

New research from Anglia Ruskin University found that women and older adults are more likely to meet exercise targets, whereas men and younger adults were less active. The study suggests that the public's increased free time during lockdown led to higher levels of physical activity.

Study: Dying stars breathe life into Earth

A new study published in Nature Astronomy sheds light on the origin of carbon in the Milky Way, revealing that dying stars play a crucial role in its synthesis. The research team found that low-mass stars shed more massive remnants than previously thought, breaking a linear trend in star formation and planetary evolution.

Behind the dead-water phenomenon

Researchers from CNRS and University of Poitiers have explained the 'dead water' phenomenon in ships, where waves create drag, slowing down or stopping vessels. The study reveals waves act like an undulating conveyor belt, causing speed oscillations in trapped boats.

When metal flows like liquid glass: a technology for producing superplastic wire is proposed

Lobachevsky University scientists have developed new ways to modify the structure of aluminium alloys, improving their performance. They used induction casting in vacuum and plastic deformation technologies to create homogeneous highly plastic structures that maintain high strength, thermal resistance, and electrical conductivity.

Scientists discover a new connection between the eyes and touch

A team of scientists at New York University has found that tiny eye movements can be used as an index of humans' ability to anticipate relevant information in the environment. The study reveals a connection between eye movements and the sense of touch, with micro-saccades hindering tactile discrimination and suppressing them enhancing it.

Harmful microbes found on sewer pipe walls

A Rutgers study reveals that sewer pipe walls harbor biofilms containing antibiotic-resistant bacteria, which can withstand standard disinfection methods. Cleaning with bleach can reduce biofilm density but not remove them entirely, posing health risks to wastewater treatment workers and the public.
