Moderate calorie restriction lowered an immune protein called C3 that appears to help drive chronic inflammation as the body ages. Blocking the same protein reduced age related inflammation in mice, raising the possibility that future treatments could mimic some benefits of calorie restriction without severe dieting.
Scientists found those who had used hormone replacement therapy were 10% less likely to be diagnosed with dementia Hormone replacement therapy may reduce the risk of dementia, a study has found. Scientists tracked more than 180,000 postmenopausal women in the UK in the largest study of its kind. They found that those who had used HRT were 10% less likely to develop any type of dementia and 16% less likely to be…
DNA from a nearly 190-year-old museum specimen has helped scientists confirm a distinct Himalayan pangolin species hiding in plain sight in Nepal and northern India. The discovery could give conservationists a powerful new way to trace illegally traded pangolin scales back to the species and regions being targeted by poachers.
A Manhattan-sized ice island has broken away from Greenland’s Petermann Glacier after years of growing fractures weakened its floating ice tongue. Scientists expect two more huge sections could soon detach, potentially removing about 22 percent of the remaining ice tongue.
French astronaut Sophie Adenot began a second spacewalk at the International Space Station on Tuesday, as she and NASA astronaut Anil Menon were set to continue work on a space-to-ground communications antenna. Adenot, a European Space Agency astronaut, was scheduled to help Menon retrieve and install a spare antenna on the station’s Z1 truss, above the Unity module, and make electrical and data connections to…
NASA’s Roman Space Telescope is now enclosed inside its Falcon Heavy fairing and nearly ready for launch. Its mission could uncover thousands of exoplanets while helping scientists investigate dark matter, dark energy, and the accelerating expansion of the universe.
“Under Salt Marsh” is returning for a second season at Sky. The crime drama has been greenlit for an “as-yet-untitled second chapter” with Rafe Spall reprising his role as Detective Eric Bull, Sky announced on Wednesday. The six-episode season will pick up as Detective Bull “moves to a remote Scottish mining village sinking under the […]
A single asteroid impact may explain two of Deimos’s most puzzling features: its huge southern depression and unusually smooth, dusty surface. Simulations suggest a roughly 320-meter asteroid struck the Martian moon at an angle, throwing debris around the entire world without breaking it apart. New observations from ESA’s Hera spacecraft support the scenario and indicate that Deimos is surprisingly porous and…

Even low levels of traffic noise can negate the benefits of listening to natural sounds, researchers say Hearing the trill or whistle of a bird while going about daily life is well known to boost people’s mood. But a new study suggests the psychological benefits of hearing birdsong are being threatened by traffic noise. Researchers found that even low levels of traffic noise negatively affected the benefits to…
Elon Musk’s company faces formidable challenges in launching millions of satellites into orbit to power AI
SpaceX unveiled plans on Tuesday for a $100 billion rocket launch complex in southern Louisiana, its largest yet, aimed at supporting Starship and AI satellite missions. The 125,000-acre Starbase Louisiana site on Pecan Island could eventually handle thousands of Starship launches annually, the company said.
A low-carb diet may raise LDL cholesterol much more sharply in people who are genetically predisposed to high cholesterol, particularly when they consume lots of saturated fat. The findings could help explain why people following seemingly similar diets can have dramatically different results.

Elon Musk’s rocket conglomerate plans its second launch complex to support more Starship launches
SpaceX says it will invest $100 billion to launch thousands of rockets from “Starbase, Louisiana,” with construction set to start in 2027.
The company says it will start construction in 2027 and that a Starship rocket could take flight as soon as 2029.
"This will be a project like no other."
One week after becoming the first French woman to perform a spacewalk, Sophie Adenot has ventured outside the International Space Station again on August 25 - with the mission of replacing an antenna.
A week after her first historic spacewalk, French astronaut Sophie Adenot began her second spacewalk outside the International Space Station (ISS) on Tuesday as part of her mission. Here are some (time-lapsed) images from the start of the extravehicular activity, which aims to replace a communications antenna. The spacewalk is expected to last around six and a half hours.
