SpaceX’s next Falcon Heavy rocket is in the hangar at NASA’s Kennedy Space Center in Florida, prepping for a launch in the coming days.

Astronomers found a large number of ancient-galaxy candidates from a single James Webb Space Telescope (JWST) image.

Astronomers peered into a James Webb Space Telescope (JWST) image. From this view of the deep Universe, they saw a large number of ancient galaxy candidates.

New tools are steadily bridging this gap. And ongoing development of one particular technique, cryo-electron tomography, or cryo-ET, has the potential to deepen how researchers study and understand how cells function in health and disease.

As the former editor-in-chief of Science magazine and as a researcher who has studied hard-to-visualize large protein structures for decades, I have witnessed astounding progress in the development of tools that can determine biological structures in detail. Just as it becomes easier to understand how complicated systems work when you know what they look like, understanding how biological structures fit together in a cell is key to understanding how organisms function.

It’s no secret that social media use can change adult brain anatomy, but a new study suggests that it may impact the developing brains of adolescents in profound ways as well.

Researchers from the University of North Carolina have found, in one of the first studies of its kind, that habitually checking social feeds may change the ways early adolescents process social rewards and punishments — changes concrete enough that they can be seen as distinct and divergent neural pathways in brain scans.

Published in the Journal of the American Medical Association Pediatrics, the paper found significant changes to the amygdala, the bit of grey matter in the brain associated with memory and emotions, in the brains of the 169 tween study participants from a rural North Carolina middle school.

German drugmaker BioNTech has struck a deal to buy U.K.-based AI startup InstaDeep for £562mn ($683mn).

While studying a nearby pair of merging galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA)—an international observatory co-operated by the U.S. National Science Foundation’s National Radio Astronomy Observatory (NRAO)—scientists discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy.

Some health conditions associated with appeared early and consistently long before diagnosis, while others became significant much later, a cohort study suggested.

For people with a subsequent diagnosis of Alzheimer’s disease, the earliest and most consistent associations at all time points over a 15-year span included depression, erectile dysfunction, gait abnormalities, hearing loss, and nervous and musculoskeletal symptoms, reported Lori Beason-Held, PhD, of the National Institute on Aging in Baltimore, and co-authors.

For those eventually diagnosed with vascular, the earliest and most consistent associations across 13 years were an abnormal electrocardiogram (EKG), cardiac dysrhythmias, cerebrovascular disease, non-epithelial skin cancer, depression, and hearing loss, the researchers reported in Annals of Neurology.

Dr. Aubrey de Grey is a legend in the longevity field who has been steadfastly promoting the idea of life extension since well before it became mainstream. While with SENS Research Foundation, de Grey made significant contributions to geroscience, and at Longevity Summit Dublin last year, he announced the creation of his new brainchild, Longevity Escape Velocity Foundation (LEVF).

Now, the first major and long-awaited LEVF-funded project is being launched: Robust Mouse Rejuvenation (RMR). This is envisioned as a rolling research program aiming to increase both the mean and maximum lifespan of mice by at least 12 months with various combination therapies started late in life. For the first study, four therapies have been chosen: rapamycin, a senolytic, hematopoietic stem cell transplantation (HSCT), and telomerase expression. A groundbreaking experiment by any measure, RMR got us excited, and we reached out to Aubrey to discuss both RMR and LEVF in depth.
