Human technology such as cell phones and broadcast towers constantly radiate radio waves ROOMand astronomers estimate that this telltale sign of humanity has been included 75 nearby star systems, signaling to any alert alien civilization that Earth hosts a technologically advanced species. And while scientists have been listening to the incessant radio chatter from our … Read more
Thousands of satellites in “megaconstellations” have been launched to meet the demand for global Internet service, and thousands more will be launched in the near future. But these small satellites have a short lifespan and, when they burn up during reentry, will release ozone-depleting pollutants. A new study in Geophysical Research Letters measures this pollution … Read more
Trade-off between relying on WM and gathering information from the outside world. a Our implicit metric for working memory (WM) usage: Copying any object requires that its identity and location information (attribute) be held in memory. Counting successful retrievals (ie, identity attribute used) and placements (ie, location attribute used) between model fixations provided a metric … Read more
HELSINKI — European-Chinese cooperation in lunar exploration may end despite successful cooperation on the ongoing Chang’e-6 mission. ESA provided a payload for China’s remote lunar sampler return mission Chang’e-6, which launched on May 3. The mission aims to collect and return samples from the lunar far side, providing unprecedented insights into the moon’s composition and … Read more
Credit: Public Domain Pixabay/CC0 Bacteriophages, viruses that attack and destroy bacteria, are ubiquitous in the natural world where they play a vital role in regulating microbial populations in ways that are not yet well understood. New research led by the University of Utah and University College London (UCL) has found that bacterial plant pathogens are … Read more
WASHINGTON – The four instruments on NASA’s Voyager 1 spacecraft are returning scientific data for the first time since a computer malfunction last November, as scientists hope to keep the mission going for another decade. NASA’s Jet Propulsion Laboratory announced June 13 that four instruments on the spacecraft, which measure plasma waves, magnetic fields and … Read more

Summary: A new study details how AI and computer simulations train robotic exoskeletons to help users conserve energy while walking, running and climbing stairs. This method eliminates the need for lengthy human-involved experiments and can be applied to various assistive devices. The breakthrough offers significant potential to help those with mobility challenges, increasing access to … Read more
In orange, the location of the Barmaz site, looking south. It is located on the plain, at the foot of the Chablais massif, which rises to an altitude of 2500 m. The site is divided into two contemporary burial areas called Barmaz I (dark blue) and Barmaz II (light blue) (Honegger and Desideri 2003, modified). … Read more
We may be entering a renaissance for human spaceflight research as record numbers of private citizens go into space — and as scientists improve techniques for gathering data for these intrepid test subjects. A sign that rebirth is imminent appeared earlier this week, when the journal Nature published a small batch of papers detailing the … Read more
