The tiny fatty capsules that deliver COVID-19 mRNA vaccines into billions of arms may work better when they're a little disorganized. That's the surprising finding from researchers who developed a new way to examine these ...

As space agencies prepare for human missions to the moon and Mars, scientists need to understand how the absence of gravity affects living cells. Now, a team of researchers has built a rugged, affordable microscope that can ...

Scientists at McGill University and the Rosalind and Morris Goodman Cancer Institute have developed a new way to deliver cancer immunotherapy that caused fewer side effects compared to standard treatment in a preclinical ...

There are many ways to communicate with prospective romantic partners. If you are a Japanese scarab beetle, it's a matter of distinguishing left from right. New work from U.S. and Chinese scientists, published this week in ...

Researchers have long been puzzled by the observed cooling of the eastern tropical Pacific and the Southern Ocean accompanying global warming. Existing climate models have failed to capture this pattern. At the Max Planck ...

Advances in supercomputing have made solving a long‐standing astronomical conundrum possible: How can we explain the changes in the chemical composition at the surface of red giant stars as they evolve?

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two neutron stars collide, they ...

Almost half a century ago, a remarkable molecule called metallocene took center stage in chemistry, earning Geoffrey Wilkinson and Ernst Otto Fischer the Nobel Prize. These organic compounds, made of a transition metal "sandwiched" ...

Like many scientists, theoretical physicist Andrew Strominger was unimpressed with early attempts at probing ChatGPT, receiving clever-sounding answers that didn't stand up to scrutiny. So he was skeptical when a talented ...

Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO J2108+5157. The new study, published February 11 on the arXiv preprint server, tries to unravel the mysterious ...

Many insects rely on heritable bacterial endosymbionts for essential nutrients that they cannot get through their diet. A new study, published in Nature Communications, indicates that the genomes of these symbiotic bacteria ...

With a new mathematical model, a team of biophysicists has revealed fresh insights into how biological tissues are shaped by the active motion of structural imperfections known as "topological defects." Published in Physical ...
