The two interstellar meteorites identified so far seem to be significantly stronger than local meteorites, which may mean they formed in supernovae.
Over the past few decades, the performance of machine learning models on various real-world tasks has improved significantly. Training and implementing most of these models, however, still requires vast amounts of energy and computational power.
Engineers worldwide have thus been trying to develop alternative hardware solutions that can run artificial intelligence models more efficiently, as this could promote their widespread use and increase their sustainability. Some of these solutions are based on memristors, memory devices that can store information without consuming energy.
Researchers at Université Paris-Saclay-CNRS, Université Grenoble-Alpes-CEA-LETI, HawAI.tech, Sorbonne Université, and Aix-Marseille Université-CNRS have recently created a so-called Bayesian machine (i.e., an AI approach that performs computations based on Bayes’ theorem), using memristors. Their proposed system, introduced in a paper published in Nature Electronics, was found to be significantly more energy-efficient than currently employed hardware solutions.
Analysis of chatter on dark web forums shows that efforts are already under way to use OpenAI’s chatbot to help script malware.
Modern humans have a youthful brain, and this “Peter Pan syndrome” is also seen in Neanderthals.
Many believe our particularly large brain is what makes us human — but is there more to it? The brain’s shape, as well as the shapes of its component parts (lobes) may also be important.
LIGHTNING super-resolution detection concept and TauSense technology facilitate better cryogenic fluorescence imaging for advanced cryo-correlative workflows. The quality of fluorescence microscope images that guide cryo-FIB milling determines the result of the prepared lamella. Here, it is described how image quality is significantly improved by LIGHTNING and how different structures can be discerned using their fluorescence lifetime-based information.
Newspaper headlines from the U.S. to the U.K. and most places in between highlight the surge in sick patients suffering from respiratory viruses. The so-called “tripledemic” of lung infections including respiratory synclinal virus (RSV), influenza (flu) and COVID-19 (coronavirus) is likely to last throughout the winter season. This explosion of infections requires more treatment options to support overloaded hospitals and overworked medics as they restore people’s health.
It has been known for a long time that intubation of an infant with any lung condition, or even an adult with severe COVID-19 using either ventilation or extra-corporeal membrane oxygenation (ECMO), comes with risks and side effects that could cause permanent damage not limited to the lungs. However, hypoxia, which means oxygen deficiency, is a medical emergency that is a common complication of severe lung infections. If not treated, it can lead to severe disability and even death.
Cyclists are supposed to wear helmets to protect them from any untoward accidents while riding through the city on their bicycles. While the helmet can protect from serious brain injury, other parts of the body can be exposed to both minor and serious injuries in case they encounter other vehicles and even pedestrians. It would be nice if there’s a sort of airbag that can shield them from injuries in case an accident happens and that said airbag will be portable enough for them to carry around.

A new algorithm is probably not efficient enough to crack current encryption keys — but that’s no reason for complacency, researchers say.
Researchers in Brazil have achieved a quantum breakthrough by succeeding in the creation of a source of illumination that produces two separate entangled beams of light, according to new research.
The achievement was announced by a team of physicists with Brazil’s Laboratory for Coherent Manipulation of Atoms and Light (LMCAL), located at the University of São Paulo’s Physics Institute.
Quantum entanglement is among the most perplexing phenomena observed in modern physics. It involves particles that are linked in such a way that when changes affect the quantum state of one, the other to which it is “entangled” will also be affected. Strangely, such effects even occur over significant distances, a phenomenon first described as “spooky action at a distance” after its discussion in a landmark 1935 paper by Albert Einstein, Boris Podolsky, and Nathan Rosen.
When the Fermi Gamma-Ray Space Telescope entered low-Earth orbit in 2008, it opened our eyes to a whole new Universe of high-energy radiation.
One of its more curious discoveries was the Fermi Bubbles: giant, symmetrical blobs extending above and below the galactic plane, 25,000 light-years on each side from the Milky Way’s center, glowing in gamma-ray light – the highest energy wavelength ranges on the electromagnetic spectrum.
Then, in 2020, an X-ray telescope named eROSITA found another surprise: even bigger bubbles extending over 45,000 light-years on each side of the galactic plane, this time emitting less energetic X-rays.
