Phys.org / Mineral clues in Gale Crater track ancient Mars climate change
While NASA imagery has shown evidence of ancient rivers and lakes on Mars that transitioned to dry dunes, uncertainty remains over the timing of the environmental changes that may have contributed to these shifts.
Phys.org / New ammonia-making method could upend one of industry's dirtiest processes
As our world's population grows, so does the demand for ammonia—a key ingredient in fertilizer. The International Renewable Energy Agency estimates that ammonia production must quadruple by 2050 to feed the increase in global ...
Tech Xplore / Misbehaving chatbots could be kept in check with personality tests
Artificial intelligence chatbots need to work on their social judgment, recent events suggest. At one end of the spectrum, they're facing lawsuits for recommending dangerous actions. At the other end, the models can be so ...
Phys.org / Moon base missions face an unseen threat, and these simulations show where it could strike first
Researchers have developed a novel virtual model for simulating how astronauts in future moon base operations might interact with each other and with their environment, with preliminary simulations revealing potential opportunities ...
Tech Xplore / Sodium-ion batteries could become a low-cost rival to Tesla's batteries
A popular sodium-ion battery designed by the company Hina and used in cars and large-scale energy storage systems in China matches performance parameters and production quality of Tesla's lithium-ion batteries, finds new ...
Medical Xpress / High-puff e-cigarettes may become more toxic with use, researchers warn
A University of California, Riverside-led study has found that heavily used high-puff electronic cigarettes may contain higher levels of harmful chemicals than fresh e-cigarettes, raising concerns about potential health risks ...
Medical Xpress / Scientists uncover how Alzheimer's may quietly begin years before memory loss appears
A new Columbia study has found clues of Alzheimer's beginnings, revealing how tau filaments—protein clumps that are closely linked to memory decline in Alzheimer's disease—get their start. The finding raises the prospect ...
