NASA’s Space Launch System has had a tricky start NASA/Cory Huston NASA is shaking up the plan for its Artemis moon missions. In a press conference on 27 February, NASA administrator Jared Isaacman announced significant changes to the agency’s plans to send humans to the moon for the first time since the Apollo programme ended […]

When artificial intelligence (AI) is allowed to behave more like a human communicator, it becomes a more effective debate partner that reaches more accurate conclusions, scientists have found. Human communication is full of stops and starts, impassioned interruptions, unsure silences and ambiguity. AI, on the other hand, adheres to the formal communication style of computers

But unless women’s voices, labor and lived realities are embedded in its foundations, it risks reinforcing the very inequities it claims to solve.  In many parts of the world, women stand on the frontlines of climate stress. According to the United Nations, if current trends continue, an estimated 341 million women will still lack electricity in 2030—85 percent of them in

Published on Fri May 17 2024 Joy | Alan Cleaver on Flickr A recent pilot study by researchers in the UK exploring the use of a ketogenic diet as a potential treatment for bipolar disorder has yielded promising results, suggesting it may be a feasible and acceptable intervention for some patients. The study, which involved

Hadrotarsinae Thorell, 1881 is a subfamily of cobweb spiders (Theridiidae) distributed worldwide and generally regarded as specialized ant predators. The taxonomy of Hadrotarsinae is problematic due to unclear delimitation of genera, leading to likely misplacement of many species. In the current paper, we provide taxonomic amendments for Emertonella Bryant, 1945, Euryopis Menge, 1868, and Phycosoma O. Pickard-Cambridge, 1880 based on Chinese materials. Examination of Eu. deplanata Schenkel,

Proteins are the molecular machines of life. Every cell in every living organism depends on proteins to survive, grow, communicate, and respond to the environment. From building tissues to catalyzing life-sustaining chemical reactions, proteins are essential biological macromolecules. In this detailed, student-friendly guide, we will explore proteins, amino acids, peptide bonds, side chains (R groups),

Have you ever imagined a life without today’s telecommunication?  Long ago when even electricity was unknown, forget about telephones and mobiles, this is a time when civilizations communicated through birds, letters, or human messengers. For instance, the Inca Empire, flourishing in South America from the 15th to the 16th century, utilized a sophisticated network of

China’s reusable space plane is circling Earth once again. The Shenlong (“Divine Dragon”) spacecraft launched from Jiuquan Satellite Launch Center in the Gobi Desert on Feb. 6, kicking off the robotic vehicle’s fourth-ever orbital mission. What exactly is it doing up there? You may like We don’t know for sure. The Chinese government has revealed

Astronomy has long been dominated by expert amateurs but with geospatial data everywhere, thanks to widely available internet and smartphones, it is not just that directions that were once only available in a paper map are now updated on your phone in real time to account for traffic. It is changing the relationships of science also.

People who can’t stop scratching itches may finally have a culprit to blame. In mice (and probably people), a protein called TRPV4 is involved both in starting an itch and stopping it after scratching, says neuroscientist Roberta Gualdani. She will present the finding February 24 at the annual meeting of the Biophysical Society in San
