Phys.org / Asteroid impact simulation reveals the hidden strength of space rocks
Physicists at the University of Oxford have contributed to a new study which has found that iron-rich asteroids can tolerate far more energy than previously thought without breaking apart—a breakthrough with direct implications ...
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 / Ultrasonic sensor capable enables cuffless, non-invasive blood pressure measurement
A new technology has been developed that enables cuffless noninvasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter—without the need for a traditional cuff. The technology ...
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 / 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 / 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 / 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 / Coffee as a staining agent substitute in electron microscopy
To ensure that the tissue structures of biological samples are easily recognizable under the electron microscope, they are treated with a staining agent. The standard staining agent for this is uranyl acetate. However, some ...
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 / Study offers possible solution to a gravitational wave mystery
Scientists at the University of Colorado Boulder may have solved a pressing mystery about the universe's gravitational wave background.
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 / Deep Sulawesi cave dig could reveal overlap between extinct humans and us
Could Homo sapiens and an archaic and now-extinct species of early human have lived alongside each other on the Indonesian island of Sulawesi more than 65,000 years ago?
