Defense advanced research projects agency — DARPA.

DARPA and the U.S. Air Force (USAF) today announced successful completion of captive carry tests of two variants of the Hypersonic Air-breathing Weapon Concept (HAWC) and are ready to proceed to first free-flight testing within the calendar year. The joint Agency and Service effort seeks to develop and demonstrate critical technologies to enable an effective and affordable air-launched hypersonic cruise missile.

HAWC performers Lockheed Martin and Raytheon Technologies have each tested advanced air vehicle configurations that promise to achieve and sustain efficient hypersonic flight. Their upcoming flight tests will focus on hydrocarbon scramjet-powered propulsion and thermal management techniques to enable prolonged hypersonic cruise, in addition to affordable system designs and manufacturing approaches.

Sleep has critical roles in health and regeneration, and one of those is clearing the brain of metabolic waste, according to researchers from the US and Denmark.

Now, as reported in the journal Nature Communications, they’ve discovered in mice that the time of day matters, suggesting the process is controlled by circadian rhythms.

“Our group has shown that just being awake or asleep drastically changes how well the brain can clear waste,” says lead author Lauren Hablitz from the University of Rochester Medical Centre.

A total of 5,726 participants had their memory tested. Out of the 24 substances that were assessed for improving memory, these are the 5 most promising nootropics.

The self-driving car could transform our ideas of space and time, enabling us to do more of the things we love and less of the ones we loathe. Here are some of the most fascinating potential uses.

A banner streak of wealth gains came to an end Thursday for the world’s richest technology billionaires.

The industry’s 10 wealthiest people had $44 billion erased from their collective net worths as U.S. equities tumbled the most in almost three months over investor concerns about frothy valuations.

Groups of stars can tear their planet-forming disk to shreds, leaving behind warped, misaligned rings, scientists find in a breakthrough study.

Solar systems like ours generally form with their planets all orbiting in the same, flat plane. But, as an international team of scientists has found in a new study, this isn’t always the case.

Please have a listen to Episode 14 of Cosmic Controversy with guest Julie Castillo, NASA’s Dawn mission project scientist. We spend much of the episode discussing the beguiling dwarf planet Ceres and the need for a sample return mission.

This week’s guest is NASA Dawn project scientist Julie Castillo-Rogez who led the hugely successful robotic mission on the first in-depth look at the asteroid Vesta and the dwarf planet Ceres. Castillo talks about why there’s a growing consensus that Ceres may have long had habitable subsurface conditions and why we need a sample return mission to launch in 2033. We also discuss Mars’ moons of Deimos and Phobos and the first interstellar asteroid, Oumuamua.

The researchers, Prof. Itamar Kahn of the Technion’s Rappaport Faculty of Medicine in Israel and Prof. Nancy Ratner of Cincinnati Children’s Hospital Medical Center (CCHMC), claimed that such a breakthrough demonstrates a potential new treatment for cognitive damages in the brain white matter, the areas of the central nervous system.
