Phys.org / Supercomputer simulation predicts time-resolved porosity in die casting
Aluminum die-cast components are widely used in automotive and precision machinery applications due to their combination of low weight and structural strength. However, internal defects known as porosity—voids formed by entrapped ...
Phys.org / Wild Canadian freshwater fish reveal opioid and antidepressant buildup downstream
Fish living downstream of wastewater treatment plants are accumulating antidepressants, opioids and other drugs of abuse in their bodies, according to a new study. Using a new analytical method they developed, a team of researchers ...
Phys.org / New open-source Python-based software boosts space-weather modeling
University of Birmingham experts have created open-source computer software that helps scientists understand how fast-moving particles behave when they interact with electromagnetic waves in space. Understanding how these ...
Phys.org / Ancient charcoal sheds new light on how early humans fueled their lives
Nearly 800,000 years ago, early humans gathered along the shores of a lush lake in what is now northern Israel. Here, they returned again and again, hunting large animals, cooking fish over controlled fires, and organizing ...
Phys.org / CRISPR variant selectively targets tumor DNA
Cancer cells excel at evading detection, but subtle chemical differences set them apart from healthy cells. Now, a team of scientists from Wageningen University & Research and Van Andel Institute has identified a way to exploit ...
Phys.org / Droplet impacts reveal surprising physics in shear-thickening fluids
From ketchup to quicksand, non-Newtonian fluids have long fascinated and puzzled scientists. Unlike ordinary fluids, their flow properties change depending on how much force is applied, but the precise mechanics governing ...
Phys.org / Scientists develop 'light switch' for the love hormone
Researchers have developed a molecular "light switch" for the so-called love hormone oxytocin, offering new insights into how social behavior, partnership bonding, emotions, and mental health are wired in the brain. Professor ...
Medical Xpress / New imaging tools help cancer researchers see inside living cells
A new study co-led by an Oregon Health & Science University researcher describes a breakthrough in microscopy tools that could dramatically expand how cancer biology labs study the inner workings of living cells. The research, ...
Phys.org / Chandra explores interstellar medium of a bright low-mass X-ray binary
Using NASA's Chandra X-ray space telescope, astronomers have performed high-resolution X-ray spectroscopic observations of a bright low-mass X-ray binary known as GX 340+0. Results of the observational campaign, published ...
Phys.org / Alien life may hide in plain sight: Statistical patterns across exoplanets move beyond traditional biosignatures
A research team has developed a new approach to detecting life beyond Earth that does not rely on identifying specific biological markers. Instead, the study suggests that life may be detectable through patterns emerging ...
Phys.org / Electrons crack open organic solar cells, exposing their hidden 3D molecular architecture in a single microscope
How do organic solar cells work on the inside? The answer lies in structures far too small to see—and difficult to access even with advanced techniques. So far, researchers have relied mainly on X-ray methods to understand ...
Phys.org / Are aliens real? Scientists have been hunting for extraterrestrial life since the time of Aristotle
Do aliens exist? Could Earth really be the only planet hosting intelligent life?
