Phys.org / Nanoplastics: New method provides clearer picture of the risks

Micro- and nanoplastics are now popping up everywhere: in seawater, snow, food and even in our bodies. The very smallest particles, in particular, are difficult to measure, meaning we still know too little about their spread ...

Phys.org / Ripple-like rings of the 'Bullseye galaxy' could be explained by dark matter

Two U.S. physicists have suggested that the nine concentric rings surrounding the galaxy LEDA 1313424, also known as the Bullseye galaxy, could have emerged through the quantum behavior of particles of dark matter. Through ...

Phys.org / 42-year study tracks how 'forever chemicals' move through the Great Lakes

University of Notre Dame researchers analyzed 42 years of biological records from the Great Lakes, unveiling how per- and polyfluoroalkyl substances (PFAS), or "forever chemicals," have moved across the region, contaminating ...

Phys.org / Hidden electric space waves are quietly cleaning Earth's 'killer' electrons

High above our heads, a silent battle is unfolding within Earth's magnetic shield. For decades, scientists have tracked "killer electrons"—ultrafast particles capable of piercing satellite armor and endangering astronauts ...

Phys.org / Pigeons' eyes are almost perfectly still when they're flying, study finds

When pigeons are flying through the air, they lock their eyes in a near-fixed position instead of moving them around. Researchers from Harvard University discovered this after attaching a lightweight rig of cameras and mirrors ...

Phys.org / LipidCruncher platform makes molecular data analysis more transparent and reproducible

Scientists studying lipids—the fatty molecules that store energy, make up cell membranes and act as signals—produce enormous amounts of information. A single experiment can detect thousands of different lipid molecules, generating ...
