Mysterious dashes revealed in Milky Way's center      (via sciencedaily.com)     Original source 

In the early 1980s, astronomers discovered gigantic, one-dimensional filaments dangling vertically near Sagittarius A*, our galaxy's central supermassive black hole. Now, astronomers have discovered a new population of filaments -- but these threads are much shorter and lie horizontally or radially, spreading out like spokes on a wheel from the black hole.

Researchers cultivate archaea that break down crude oil in novel ways      (via sciencedaily.com)     Original source 

The seafloor is home to around one-third of all the microorganisms on the Earth and is inhabited even at a depth of several kilometers. Only when it becomes too hot does the abundance of microorganisms appear to decline. But how, and from what, do microorganisms in the deep seafloor live? How do their metabolic cycles work and how do the individual members of these buried communities interact? Researchers have now been able to demonstrate in laboratory cultures how small, liquid components of crude oil are broken down through a new mechanism by a group of microorganisms called archaea.

Little-known microbes could help predict climate tipping points      (via sciencedaily.com)     Original source 

Rising temperatures could push ocean plankton and other single-celled creatures toward a carbon tipping point that fuels more warming. The carbon-eaters could become carbon-emitters. But new research shows it's also possible to detect early distress signals before they get there.

Finally solved! The great mystery of quantized vortex motion      (via sciencedaily.com)     Original source 

Scientists investigated numerically the interaction between a quantized vortex and a normal-fluid. Based on the experimental results, researchers decided the most consistent of several theoretical models. They found that a model that accounts for changes in the normal-fluid and incorporates more theoretically accurate mutual friction is the most compatible with the experimental results.

Flat fullerene fragments attractive to electrons      (via sciencedaily.com)     Original source 

Researchers have gained new insights into the unique chemical properties of spherical molecules composed entirely of carbon atoms, called fullerenes. They did it by making flat fragments of the molecules, which surprisingly retained and even enhanced some key chemical properties.

Petit-spot volcanoes involve the deepest known submarine hydrothermal activity, possibly release CO2 and methane      (via sciencedaily.com)     Original source 

Underwater volcanism and its hydrothermal activity play an important role in marine biogeochemical cycles, especially the carbon cycle. But the nature of hydrothermal activity at 'petit-spot' volcanoes have not been revealed at all. Now, scientists reveal that petit-spot hydrothermal activity occurs on the deepest seafloor known to date and could release carbon dioxide (CO2) and methane, which may have implications for the global carbon cycle.

Symbiotic and pathogenic fungi may use similar molecular tools to manipulate plants      (via sciencedaily.com)     Original source 

Symbiotic and pathogenic fungi that interact with plants are distantly related and don't share many genetic similarities. Comparing plant pathogenic fungi and plant symbiotic fungi, scientists at the Sainsbury Laboratory Cambridge University (SLCU) have discovered that these remote relatives are using a similar group of proteins to manipulate and live within plants.

Ticks prove resilient to extreme temperatures      (via sciencedaily.com)     Original source 

A recent study shows blacklegged ticks (Ixodes scapularis) are actually really good at surviving extreme cold and heat in nature. Previous lab research suggests that even short periods of especially warm or cold conditions should easily kill ticks, but the a new analysis reveals this is only the case for larval ticks in the environment.

New method improves efficiency of 'vision transformer' AI systems      (via sciencedaily.com)     Original source 

Vision transformers (ViTs) are powerful artificial intelligence (AI) technologies that can identify or categorize objects in images -- however, there are significant challenges related to both computing power requirements and decision-making transparency. Researchers have now developed a new methodology that addresses both challenges, while also improving the ViT's ability to identify, classify and segment objects in images.
