Phys.org / 40-year-old prediction of how plastics 'mix' confirmed for the first time
A "mixing" phenomenon between plastic layers that had been predicted only in theory for 40 years has now been experimentally confirmed.
Phys.org / Blue light breaks long-standing chemistry rule, unlocking 3D drug building blocks
For more than a century, pharmaceutical companies have relied on flat structures called aromatic rings, which can help drugs bind to target sites in the body. They include benzene rings and other flat, nitrogen-containing ...
Medical Xpress / Pancreatic tumors use clotting pathway to build immune shields, study finds
Researchers at the Icahn School of Medicine at Mount Sinai have found that small populations of pancreatic cancer cells can create localized immune-protective niches that shield tumors from immune attack. The finding could ...
Medical Xpress / Protein restriction may trigger body-wide program linked to longer life
A new perspective from LSU's Pennington Biomedical Research Center proposes a new way of understanding how dietary protein restriction may promote healthy aging and extend lifespan: through a coordinated physiological response ...
Phys.org / Continuous video of black hole radio observations challenges shock wave theory
For years, scientists have relied primarily on radio imaging from techniques like very long baseline interferometry (VLBI) to study jets from the active galactic nuclei of supermassive black holes. This allows for the detection ...
Phys.org / Study explores new photonics advance: Topology imprinting in nonlinear metasurfaces
Light is traditionally described by properties such as wavelength, amplitude, phase and polarization. Advances in optics have shown that light can also be shaped into complex spatial patterns known as structured light, enabling ...
Medical Xpress / AI tool successfully predicts outcomes of immunotherapy in lung cancer
Artificial intelligence (AI) tools can help physicians predict treatment and survival outcomes in patients with advanced non-small cell lung cancer (NSCLC) treated with immunotherapy, according to a new study published in ...
Medical Xpress / Miniaturized bone marrow-on-a-chip tracks human immune cells as they build lasting antibody defenses
A scientific team has developed a laboratory model that reveals how antibody-producing plasma cells migrate, mature and survive within human bone marrow, a main location of long-lived antibody-producing plasma cells. The ...
Phys.org / Series of reactions reveals how complex carbon chemistry can begin in frigid space
Before there was Earth, there was chemistry. In the unimaginable cold, dark clouds where stars and planets are born, carbon molecules assemble into more complex forms—starting a chemical journey that could eventually deliver ...
Phys.org / No cities on the moon—there isn't enough water, scientists say
The discovery of water in dark craters at the moon's poles has sparked a "moon rush" to establish bases there, followed by villages, cities and heavy industry. How sustainable is this rush?
Phys.org / Antibody cocktails could steer viruses into evolutionary dead ends
When a virus mutates, the world usually finds out the hard way. Variants of influenza and SARS-CoV-2 can slip past vaccines and antibody drugs before scientists fully understand what has changed. A new study from Harvard's ...
Phys.org / Anger, hope and compassion do little to spur more climate donations
Emotional mechanisms are frequently used to inspire good environmental behavior. But how effective are they at inspiring actual sustainable change? Perhaps not as much as previously believed, according to a new study that ...
