Expiring medications could pose challenge on long space missions      (via sciencedaily.com)     Original source 

A new study shows that over half of the medicines stocked in space -- staples such as pain relievers, antibiotics, allergy medicines, and sleep aids -- would expire before astronauts could return to Earth.

Are AI-chatbots suitable for hospitals?      (via sciencedaily.com)     Original source 

Large language models may pass medical exams with flying colors but using them for diagnoses would currently be grossly negligent. Medical chatbots make hasty diagnoses, do not adhere to guidelines, and would put patients' lives at risk. A team has systematically investigated whether this form of artificial intelligence (AI) would be suitable for everyday clinical practice. Despite the current shortcomings, the researchers see potential in the technology. They have published a method that can be used to test the reliability of future medical chatbots.

Life signs could survive near surfaces of Enceladus and Europa      (via sciencedaily.com)     Original source 

Europa and Enceladus, icy moons of Jupiter and Saturn respectively, have evidence of oceans beneath their crusts. A NASA experiment suggests -- if these oceans support life -- signatures of that life in the form of organic molecules (like amino acids and nucleic acids) could survive just under the surface ice despite the harsh, ionizing radiation on these worlds. If robotic landers were to go to these moons to look for life signs, they would not have to dig very deep to find amino acids that have survived being altered or destroyed by radiation.

Revolutionizing the abilities of adaptive radar with AI      (via sciencedaily.com)     Original source 

Engineers have shown that using a type of AI that revolutionized computer vision can greatly enhance modern adaptive radar systems. And in a move that parallels the impetus of the computer vision boom, they have released a large dataset of digital landscapes for others to build on their work.

New dawn for space storm alerts could help shield Earth's tech      (via sciencedaily.com)     Original source 

Space storms could soon be forecasted with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth. Scientists say it is now possible to predict the precise speed a coronal mass ejection (CME) is travelling at and when it will smash into our planet -- even before it has fully erupted from the Sun.

Exoplanet-hunting telescope to begin search for another Earth in 2026      (via sciencedaily.com)     Original source 

Europe's next big space mission -- a telescope that will hunt for Earth-like rocky planets outside of our solar system -- is on course to launch at the end of 2026. PLATO, or PLAnetary Transits and Oscillations of stars, is being built to find nearby potentially habitable worlds around Sun-like stars that we can examine in detail.

Another intermediate-mass black hole discovered at the center of our galaxy      (via sciencedaily.com)     Original source 

So far, only about ten intermediate-mass black holes have been discovered in the entire universe. The newly identified black hole causes surrounding stars in a cluster to move in an unexpectedly orderly way.

Does the type of workstation you use make a difference in your health and productivity?      (via sciencedaily.com)     Original source 

Although devices such as standing desks have been found to alleviate physical symptoms and increase worker productivity, questions remain regarding the best use of the primary types of workstations -- stand-biased, sit-stand or traditional -- for increasing workers' physical activity and preventing health problems. To answer these questions, researchers measured the computer usage and activity levels of 61 office workers for 10 days to evaluate any discomfort and develop possible remedies.

Ant insights lead to robot navigation breakthrough      (via sciencedaily.com)     Original source 

Have you ever wondered how insects are able to go so far beyond their home and still find their way? The answer to this question is not only relevant to biology but also to making the AI for tiny, autonomous robots. Drone-researchers felt inspired by biological findings on how ants visually recognize their environment and combine it with counting their steps in order to get safely back home. They have used these insights to create an insect-inspired autonomous navigation strategy for tiny, lightweight robots. It allows such robots to come back home after long trajectories, while requiring extremely little computation and memory (0.65 kiloByte per 100 m). In the future, tiny autonomous robots could find a wide range of uses, from monitoring stock in warehouses to finding gas leaks in industrial sites.

Paving the way to extremely fast, compact computer memory      (via sciencedaily.com)     Original source 

Researchers have demonstrated that the layered multiferroic material nickel iodide (NiI2) may be the best candidate yet for devices such as magnetic computer memory that are extremely fast and compact. Specifically, they found that NiI2 has greater magnetoelectric coupling than any known material of its kind.

The magnet trick: New invention makes vibrations disappear      (via sciencedaily.com)     Original source 

Damping vibrations is crucial for precision experiments, for example in astronomy. A new invention uses a special kind of magnets to achieve this -- electropermanent magnets. They consist of a permanent magnet and a coil. In contrast to electromagnets, they do not have to be permanently supplied with energy. In contrast to permanent magnets, their strength can be tuned: Whenever necessary, a strong electric pulse is sent through the coil, adapting the properties of the magnet.

How astronomers are using pulsars to observe evidence of dark matter      (via sciencedaily.com)     Original source 

Tantalizing evidence of potential dark matter objects has been detected with the help of the Universe's 'timekeepers'. These pulsars -- neutron stars which rotate and emit lighthouse-like beams of radio waves that rapidly sweep through space -- were used to identify mysterious hidden masses. Pulsars earned their nickname because they send out electromagnetic radiation at very regular intervals, ranging from milliseconds to seconds, making them extremely accurate timekeepers.

Sun-like stars found orbiting hidden companions      (via sciencedaily.com)     Original source 

Astronomers have uncovered what appear to be 21 neutron stars in orbit around stars like our Sun. The discovery is surprising because it is not clear how a star that exploded winds up next to a star like our Sun.

Food aroma study may help explain why meals taste bad in space      (via sciencedaily.com)     Original source 

A new study on common food aromas may help explain why astronauts report that meals taste bland in space and struggle to eat their normal nutritional intake. This research has broader implications for improving the diets of isolated people, including nursing home residents, by personalizing aromas to enhance the flavor of their food.
