Phys.org / NASA cancels spacewalk due to medical issue and may bring the crew back early
NASA canceled its first spacewalk of the year and may bring its crew back early from the International Space Station due to an onboard medical issue.
Phys.org / Astrophysicists map how many ghost particles all the Milky Way's stars send towards Earth
They're called ghost particles for a reason. They're everywhere—trillions of them constantly stream through everything: our bodies, our planet, even the entire cosmos. These so-called neutrinos are elementary particles ...
Phys.org / Behind nature's blueprints: Physicists create 'theoretical rulebook' of self-assembly
Inspired by biological systems, materials scientists have long sought to harness self-assembly to build nanomaterials. The challenge: the process seemed random and notoriously difficult to predict.
Phys.org / Cells use Morse code-like rhythms to coordinate growth
Cells experience many different types of stress, such as starvation or stress caused by too much salt or too high a temperature. Insulin signals respond to such stress signals by sending the protein DAF-16 into the cell nucleus ...
Phys.org / How population bottlenecks shape bacterial cooperation and competition
Microbes often display cooperative behavior in which individual cells put in work and sacrifice resources to collectively benefit the group. But sometimes, "cheater" cells in the group may reap the benefits of this cooperation ...
Phys.org / Frequent Arctic wildfires could cut snow cover by 18 days, impacting global climate and ecology
The correlation between Arctic wildfires and abnormal snow cover under global warming is of growing concern. A comprehensive quantitative assessment by researchers at The Hong Kong Polytechnic University (PolyU) has shown ...
Phys.org / Cosmic lens reveals hyperactive cradle of future galaxy cluster
Galaxy clusters are formed by a dense packing of many galaxies, making them the most massive structures in the universe. Their progenitors, protoclusters, show these galaxies in their infancy, offering a window to study how ...
Phys.org / Portable biosensor could enable on-site PFAS detection
A portable biosensor developed at La Trobe University may allow rapid, on-site detection of toxic "forever chemicals" in water, removing the need for samples to be sent to specialist laboratories.
Phys.org / Repeating fast radio burst shows diverse activity and hints at magnetar origin
Using the upgraded Giant Metrewave Radio Telescope (uGMRT), Indian astronomers have performed multi-frequency observations of a repeating fast radio burst designated FRB 20201124A. Results of these observations shed more ...
Phys.org / Global study reveals widespread burning of plastic for heating and cooking
A new Curtin University-led study has shed new light on the widespread number of households in developing countries burning plastic as an everyday energy source, uncovering serious international health, social equality and ...
Phys.org / Searching for the centromere: Diversity in pathways key for cell division
Despite the immense amount of genetic material present in each cell, around 3 billion base pairs in humans, this material needs to be accurately divided in two and allocated in equal quantities. The centromere, located in ...
Phys.org / Dark matter and neutrinos may interact, challenging standard model of the universe
Scientists are a step closer to solving one of the universe's biggest mysteries as new research finds evidence that two of its least understood components may be interacting, offering a rare window into the darkest recesses ...
