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?
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 / 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 / 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 / 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 / Antiferromagnetic metal exhibits diode-like behavior without external magnetic field
Antiferromagnetic (AF) materials are made up of atoms or molecules with atomic spins that align in antiparallel directions of their neighbors. The magnetism of each individual atom or molecule is canceled out by the one next ...
Medical Xpress / Auto-brewery syndrome: What causes some people's gut microbes to produce high alcohol levels?
Researchers at University of California San Diego, Mass General Brigham, and their colleagues have identified specific gut bacteria and metabolic pathways that drive alcohol production in patients with auto-brewery syndrome ...
Medical Xpress / Stem cell engineering progress paves way for next-generation living drugs
For the first time, researchers at the University of British Columbia have demonstrated how to reliably produce an important type of human immune cell—known as helper T cells—from stem cells in a controlled laboratory ...
Medical Xpress / Stem cell therapy for stroke shows how cells find their way in the brain
Some parts of our bodies bounce back from injury in fairly short order. The outer protective layer of the eye—called the cornea—can heal from minor scratches within a single day. The brain is not one of these fast-healing ...
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 ...
Medical Xpress / COVID-19 still claims more than 100,000 US lives each year
Centers for Disease Control and Prevention researchers report national estimates of 43.6 million COVID-19-associated illnesses and 101,300 deaths in the US during October 2022 to September 2023, plus 33.0 million illnesses ...
