NASA's X-59 jet broke the sound barrier for the first time on Friday (June 5), reaching a top speed of about Mach 1.1.

So far, archaeologists have recovered 40 artifacts from the discovery, an 18th-century shipwreck that likely will yield thousands more treasures

NASA’s experimental X-59 aircraft marked a major milestone Friday, June 5, when it flew faster than the speed of sound for the first time, setting the stage for demonstrating its quiet supersonic capabilities later this year.  NASA test pilot Jim “Clue” Less took off and landed at Edwards Air Force Base in California, reaching a top speed of approximately Mach 1.1 (713 mph) and altitude of 43,400 feet. The X-59’s flight began at 11:08 a.m. PDT and lasted 81 minutes, with the team focusing on flying qualities at both subsonic and then […]

Waves of light and sound interact to drive electronic and structural changes in a perovskite crystal. At the atomic scale, nothing is ever truly still. Materials that appear perfectly rigid and motionless to the naked eye are in fact swarms of vibrating atoms. This motion is generally random and uncoordinated, but with the right input, the atoms in certain materials will start to move together, vibrating in sync.

After searching for 50 years, astronomers have finally discovered powerful winds blowing from Sagittarius A*, the supermassive black hole at the heart of our galaxy.

Scientists have been searching for evidence of this breeze since the 1970s. They've seen intense wind from other black holes, but they've struggled to observe the one at the Milky Way's center

Many animals, including humans, rely on their eyes to detect changes in their surroundings. The eyes of vertebrates, animals with a backbone or a similar supporting structure, contain a transparent structure (i.e., the lens) that focuses incoming light onto a layer of light-sensitive cells, known as the retina. Cells in the retina then convert light into signals that are sent to the brain.

University of Tennessee, Knoxville physicists and their colleagues have made critical measurements of the lifetime and decay energy of tellurium-104 (Te-104), an important step in answering a century-old question and understanding how hundreds of nuclei decay. The results are published in Nature.

In recent years, human population growth, coupled with the climate crisis, environmental pressures, and current production and consumption patterns, has driven the search for alternative food sources. With 1,611 insect species listed as edible, organizations such as the Food and Agriculture Organization of the United Nations (FAO) have proposed insects as a sustainable food source.

IS110 transposons are a large, diverse family of bacterial insertion sequences (IS elements)—small, mobile DNA elements that can move from one genomic location to another. They have recently attracted broad interest due to the finding that some of these transposons use a bridge RNA (bRNA) to recognize both donor DNA and target DNA.

Wildlife research projects worldwide could benefit from a new AI system which can automatically find, name, and follow individual animals in footage.

For many of us, a warm cup of coffee is how we start our day. For Texas A&M Health researchers, it may also offer a new way to control engineered cells in future medicines.

Working from home comes with some major pluses. It's more flexible, there's no more pesky commute, work-life balance improves, and you can even stay in your pajamas all day if you want. But according to a major study of more than 580,000 American workers published in Science, remote work is taking its toll on people's mental health.

A newly discovered photographic postcard showing women who kept Portsmouth's railways running during the First World War has been revealed by a researcher at the University of Portsmouth—and he is appealing to local people to help identify those in the image.
