Tech Xplore / Swapping batteries for hydrogen gives drones a whole new range
Researchers have built a drone that runs on hydrogen, to replace battery-powered drones that are too heavy and have too short a range. This technology could help fix power outages faster and replace dangerous helicopter missions ...
Medical Xpress / Prototype breath tests spot bacterial infections in minutes
Infectious diseases are a major cause of death worldwide, and diagnosing bacterial infections remains a challenge in medicine. And doing so reliably is more important than ever, given the increasing frequency of antibiotic ...
Phys.org / Medieval chess promoted racial harmony and mutual respect, say historians
Medieval manuscripts, paintings and chess sets reveal that the so-called "game of kings" defied social structures and racial attitudes by celebrating the intellectual prowess of winners irrespective of their skin color.
Phys.org / Mystery of quinine biosynthesis solved with newly discovered enzymes
For over 350 years, quinine and other extracts from the cinchona tree (Cinchona spp.) were the only effective medicines against malaria, a tropical fever caused by single-celled parasites of the genus Plasmodium and transmitted ...
Medical Xpress / Premature menopause raises long-term heart risk by 40%, large study reveals
Women who enter natural menopause before age 40 face about a 40% higher lifetime risk of developing coronary heart disease than women who experience menopause later, according to a large Northwestern Medicine study that is ...
Phys.org / ATCA observations probe peculiar pulsar wind nebula Vela X
Astronomers have employed the Australia Telescope Compact Array (ATCA) to investigate a peculiar pulsar wind nebula known as Vela X. Results of the new observations, published March 2 on the arXiv pre-print server, provide ...
Phys.org / Experiment observes quantum radiation reaction as electrons hit an ultra-intense laser
For the first time, a quantum radiation reaction in strong electromagnetic fields has been demonstrated experimentally by allowing electrons to collide with an extremely intense and powerful laser beam. The research findings ...
Medical Xpress / Hope for preventing stomach cancer: Drug candidate proves extremely effective against H. pylori
Researchers at the Technical University of Munich (TUM) have increased the effectiveness of a standard antibiotic by a factor of 60 through targeted chemical modifications. In laboratory and animal studies, the new drug candidate ...
Phys.org / 'Rock clock' refines time measurement of Earth's early complex animal life
How can we measure time more than 500 million years into the past? A study recently published in Nature Communications by researchers at the University of Lausanne presents a new geological "rock clock" that allows major ...
Phys.org / AI model predicts chemical effects on gene expression, speeding drug discovery
Inside a diseased cell, the genes are in chaos. Some are receiving signals to overproduce a protein. Others are reducing activity to abnormal levels. Up is down and down is up. The right molecule could restore order, reversing ...
Medical Xpress / A new digital imagery program can help students reduce anxiety levels
With exams looming and a lot potentially riding on their future, many university students suffer from anxiety. This pressure can often create a cycle of worry that is difficult to break without the right tools. A new study ...
