Solid-state qubits: Forget about being clean, embrace mess      (via sciencedaily.com)     Original source 

New findings debunk previous wisdom that solid-state qubits need to be super dilute in an ultra-clean material to achieve long lifetimes. Instead, cram lots of rare-earth ions into a crystal and some will form pairs that act as highly coherent qubits, a new paper shows.

Drinkable, carbon monoxide-infused foam enhances effectiveness of experimental cancer therapy      (via sciencedaily.com)     Original source 

The intriguing finding that smokers did better than non-smokers in a clinical trial for an experimental cancer treatment led researchers to develop a drinkable, carbon monoxide-infused foam that boosted the effectiveness of the therapy, known as autophagy inhibition, in mice and human cells. The results suggest that therapeutic levels of carbon monoxide, delivered using gas-entrapping materials (GEMs), can increase the anti-cancer activity of autophagy inhibitors, which might have potential to improve therapies for many different cancers.

The first assessment of toxic heavy metal pollution in the Southern Hemisphere over the last 2,000 years      (via sciencedaily.com)     Original source 

Human activity, from burning fossil fuels and fireplaces to the contaminated dust produced by mining, alters Earth's atmosphere in countless ways. Records of these impacts over time are preserved in everlasting polar ice that serves as a sort of time capsule, allowing scientists and historians to link Earth's history with that of human societies. In a new study, ice cores from Antartica show that lead and other toxic heavy metals linked to mining activities polluted the Southern Hemisphere as early as the 13th century.

Oldest known fossilized skin is 21 million years older than previous examples      (via sciencedaily.com)     Original source 

Researchers have identified a 3D fragment of fossilized skin that is at least 21 million years than previously described skin fossils. The skin, which belonged to an early species of Paleozoic reptile, has a pebbled surface and most closely resembles crocodile skin. It's the oldest example of preserved epidermis, the outermost layer of skin in terrestrial reptiles, birds, and mammals, which was an important evolutionary adaptation in the transition to life on land.

Prehistoric person with Turner syndrome identified from ancient DNA      (via sciencedaily.com)     Original source 

Researchers have developed a new technique to measure the number of chromosomes in ancient genomes more precisely, using it to identify the first prehistoric person with mosaic Turner syndrome (characterized by one X chromosome instead of two [XX]), who lived about 2500 years ago.

NASA's Webb discovers dusty 'cat's tail' in Beta Pictoris System      (via sciencedaily.com)     Original source 

Beta Pictoris, a young planetary system located just 63 light-years away, continues to intrigue scientists even after decades of in-depth study. It possesses the first dust disk imaged around another star -- a disk of debris produced by collisions between asteroids, comets, and planetesimals. Observations from NASA's Hubble Space Telescope revealed a second debris disk in this system, inclined with respect to the outer disk, which was seen first. Now, a team of astronomers using NASA's James Webb Space Telescope to image the Beta Pictoris system (Beta Pic) has discovered a new, previously unseen structure.

New study pinpoints the weaknesses in AI      (via sciencedaily.com)     Original source 

ChatGPT and other solutions built on Machine Learning are surging. But even the most successful algorithms have limitations. Researchers have now proven mathematically that apart from simple problems it is not possible to create algorithms for AI that will always be stable. The study may lead to guidelines on how to better test algorithms and reminds us that machines do not have human intelligence after all.

Is there a common link between the physical and social worlds? Two brothers think so      (via sciencedaily.com)     Original source 

A Rutgers biophysical chemist and his brother, a political scientist on the West Coast, have joined intellectual forces, realizing a long-standing dream of co-authoring an article that bridges their disciplines involving cells and society. In their paper, they have proposed that powerful parallels exist between the microscopic, natural world of cells and molecules and the human-forged realm of organizations and political systems.

Discovery of immense fortifications dating back 4,000 years in north-western Arabia      (via sciencedaily.com)     Original source 

The North Arabian Desert oases were inhabited by sedentary populations in the 4th and 3rd millennia BCE. A fortification enclosing the Khaybar Oasis -- one of the longest known going back to this period -- was just revealed by a team of scientists. This new walled oasis is, along with that of Tayma, one of the two largest in Saudi Arabia.
