Scientists measure the distance to stars by their music      (via sciencedaily.com)     Original source 

A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and checked the measurements taken during the Gaia mission to study the near Universe.

Coevolution helps Santa's reindeer feast after flight      (via sciencedaily.com)     Original source 

A new study suggests that it's not Rudolph's red nose that helps reindeer find food during snowy Arctic winters, but instead a unique adaptation of their eyes to their favorite food. Reindeer may have developed their unique ability to see in the ultraviolet spectrum so they can more easily spot their primary food, the algae-fungus fusion known as lichens -- which absorb UV -- in the winter landscape. The findings help explain the long-standing scientific mystery as to why reindeer -- including Rudolph and his fellow airborne ungulates from the classic story -- can see in UV.

Astronomers discover first population of binary stripped stars      (via sciencedaily.com)     Original source 

Astronomers have discovered a population of massive stars that have been stripped of their hydrogen envelopes by their companions in binary systems. The findings shed light on the hot helium stars that are believed to be the origins of hydrogen-poor core-collapse supernovae and neutron star mergers.

Reaching for the (invisible) stars      (via sciencedaily.com)     Original source 

Supernovae -- stellar explosions as bright as an entire galaxy -- have fascinated us since time immemorial. Yet, there are more hydrogen-poor supernovae than astrophysicists can explain. Now, scientists may have found the missing precursor star population.

Seals stay warm and hydrated in the Arctic with larger, more convoluted nasal passages      (via sciencedaily.com)     Original source 

Arctic seals have evolved many adaptations to cope with their frosty environment -- one that you might not immediately think of is the bones in their nasal cavity. Arctic seals have more convoluted nasal passages than seal species that live in milder environments, and researchers report that these structures help the seals more efficiently retain heat and moisture as they breathe in and out.

AI study reveals individuality of tongue's surface      (via sciencedaily.com)     Original source 

Artificial Intelligence (AI) and 3D images of the human tongue have revealed that the surface of our tongues are unique to each of us, new findings suggest. The results offer an unprecedented insight into the biological make-up of our tongue's surface and how our sense of taste and touch differ from person to person.

Thinking about God inspires risk-taking for believers, study finds      (via sciencedaily.com)     Original source 

Does thinking about faith make religious people more likely to take leaps? A new study says yes, finding that participants were more likely to take risks when thinking about God as a benevolent protector.  The study specifically looked at American Christians and 'morally neutral' risks.

Viking dentistry was surprisingly advanced      (via sciencedaily.com)     Original source 

Widespread caries and toothache -- but also some dental work and filing of front teeth. Viking Age teeth from Varnhem bear witness to surprisingly advanced dentistry.

Unexpected chemistry reveals cosmic star factories' secrets      (via sciencedaily.com)     Original source 

Two galaxies in the early universe, which contain extremely productive star factories, have been studied by a team of scientists. Using powerful telescopes to split the galaxies' light into individual colors, the scientists were amazed to discover light from many different molecules -- more than ever before at such distances. Studies like this could revolutionize our understanding of the lives of the most active galaxies when the universe was young, the researchers believe.

Tiniest free-floating brown dwarf      (via sciencedaily.com)     Original source 

Brown dwarfs are objects that straddle the dividing line between stars and planets. They form like stars, growing dense enough to collapse under their own gravity, but they never become dense and hot enough to begin fusing hydrogen and turn into a star. At the low end of the scale, some brown dwarfs are comparable with giant planets, weighing just a few times the mass of Jupiter.

Earliest evidence for domestic yak found using both archaeology, ancient DNA      (via sciencedaily.com)     Original source 

The high-altitude hero of the Himalayas, yak are among the few large animals that can survive the extremely cold, harsh and oxygen-poor conditions of the Tibetan Plateau. In the mountainous regions of Asia, yak and yak-cattle hybrids serve as vital sources of meat, milk, transportation and fuel. However, little is known about their history: when or where yak were domesticated. In a new study, researchers report archaeologically and genetically confirmed evidence for domestic yak, dating back 2,500 years, by far the oldest record.

The solar forest      (via sciencedaily.com)     Original source 

What would be the most effective use of a certain plot of land in terms of the climate crisis: planting a forest, which is a natural means of absorbing carbon dioxide from the atmosphere, or erecting fields of solar panels, which reduce the emission of carbon dioxide into the atmosphere? This dilemma has long been debated by decision-makers around the world. Now, for the first time -- based on findings from arid areas and on comprehensive measurements of the energy flow exchanged between the ground and the atmosphere -- we may have an answer to this question.

Some icy exoplanets may have habitable oceans and geysers      (via sciencedaily.com)     Original source 

A new study expands the search for life beyond our solar system by indicating that 17 exoplanets (worlds outside our solar system) could have oceans of liquid water, an essential ingredient for life, beneath icy shells. Water from these oceans could occasionally erupt through the ice crust as geysers. The science team calculated the amount of geyser activity on these exoplanets, the first time these estimates have been made. They identified two exoplanets sufficiently close where signs of these eruptions could be observed with telescopes.

Can AI be too good to use?      (via sciencedaily.com)     Original source 

Much of the discussion around implementing artificial intelligence systems focuses on whether an AI application is 'trustworthy': Does it produce useful, reliable results, free of bias, while ensuring data privacy? But a new article poses a different question: What if an AI is just too good?
