Once again, politicians and judges are limiting abortion without any understanding of what pregnancy can, and often does, ask of the human body. To conservative legislators in Texas, a new law banning abortion after about six weeks of gestation is a ploy to subvert Roe v. Wade . But to doctors like me, the measure reveals how thoughtless its designers are and how willing they are to let pregnant
Introducing Altos Labs A new and somewhat shadowy Silicon Valley company dedicated to anti-aging research is getting major funding from the uber wealthy.

If you open a biology textbook and run through the images depicting how DNA is organized in the cell's nucleus, chances are you'll start feeling hungry; the chains of DNA would seem like a bowl of ramen: long strings floating in liquid. However, according to two new studies—one experimental and the other theoretical—that are the outcome of the collaboration between the groups of Prof. Talila Volk
A team of researchers from Boston College has created a new metallic specimen where the motion of electrons flows in the same way water flows in a pipe—fundamentally changing from particle-like to fluid-like dynamics, the team reports in Nature Communications.
For two decades, manipulating materials at the nanoscale to develop efficient catalysts for various applications, including water treatment, has been the gold standard in the field. But a new study goes even smaller—down to a single atom, the theoretical limit in material downsizing. And results show a big improvement in efficiency, with surprising new properties that cannot be achieved by nanomat
An international team of astronomers has detected a new ultra-hot Jupiter extrasolar planet using NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound alien world is nearly two times larger than Jupiter and has a misaligned orbit. The finding is detailed in a paper published August 25 on the arXiv pre-print repository.
A series of recent research papers from a McGill-led team has found that the herbicide glyphosate—commonly sold under the label Roundup—can alter the structure of natural freshwater bacterial and zooplankton communities. Notably, the researchers found that for zooplankton, aquatic concentrations of 0.1 mg/L glyphosate were sufficient to cause diversity loss.
Nature Communications, Published online: 06 September 2021; doi:10.1038/s41467-021-25592-6 Unlike other halogen atoms, the ability for fluorine to exist in a [C–X–C]+ connectivity pattern has only been shown in spectroscopic studies. Here the authors present a single crystal structure of a fluoronium cation, characterized by X-ray diffraction.

A popular saying in football is that a player's best ability is his availability. The idea explains why injured players in professional football are often cut, released, or relegated to lesser roles. It's why an NFL player's history of missing games can keep him from getting a big contract. It's why players who face criminal allegations are handled according to whether they'll miss time on the fi

Could dying stars hold the secret to looking younger? New evidence suggests that white dwarfs could continue to burn hydrogen in the final stages of their lives, causing them to appear more youthful than they actually are. This discovery could have consequences for how astronomers measure the ages of star clusters.
Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) and their collaborators have systematically measured the knockout cross sections of neutron-rich carbon isotopes at the intermediate- to high-energy region by using the External Target Facility (ETF) of the Cooler Storage Ring (CSR) at the Heavy Ion Research Facility in Lanzhou (HIRFL).
A supernova is a brilliant end to a giant star. For a brief moment of cosmic time, a star makes one last effort to keep shining, only to fade and collapse on itself. The end result is either a neutron star or a stellar-mass black hole. We've generally thought that all stars above about 10 solar masses will end as a supernova, but a new study suggests that isn't the case.
