Global macrogenetic map of marine habitat-forming species      (via sciencedaily.com)     Original source 

Species known as marine habitat-forming species -- gorgonians, corals, algae, seaweeds, marine phanerogams, etc.-- are organisms that help generate and structure the underwater landscapes. These are natural refuges for other species, and provide biomass and complexity to the seabeds. But these key species in marine ecosystems are currently threatened by climate change and other perturbations derived from human activity. Now, a study warns that even in the marine protected areas (MPAs) the genetic diversity of structural species is not protected, although it is essential for the response and adaptation of populations to changes that alter the natural environment.

Quantum matter breakthrough: Tuning density waves      (via sciencedaily.com)     Original source 

Scientists have found a new way to create a crystalline structure called a 'density wave' in an atomic gas. The findings can help us better understand the behavior of quantum matter, one of the most complex problems in physics.

Move over, armadillos: There's a new bone-plated mammal in town      (via sciencedaily.com)     Original source 

Armadillos have long been considered to be the only living mammals that produce protective bony plates. But a new study unexpectedly shows that African spiny mice produce the same structures beneath the skin of their tails, which until now had gone largely undetected.

Identifying the bee's knees of bumble bee diets      (via sciencedaily.com)     Original source 

A new study has identified the bee's knees of bumble bee dietary options in Ohio and the Upper Midwest. By viewing almost 23,000 bumble bee-flower interactions over two years, researchers found that these bees don't always settle for the most abundant flowers in their foraging area -- suggesting they have more discerning dietary preferences than one might expect.

Fossils of a saber-toothed top predator reveal a scramble for dominance leading up to 'the Great Dying'      (via sciencedaily.com)     Original source 

A tiger-sized saber-toothed creature called Inostrancevia has previously only been found in Russia. But scientists have discovered its fossils in South Africa, suggesting that it migrated 7,000 miles across the supercontinent Pangaea during the world's worst mass extinction 252 million years ago. Heading to South Africa allowed it to fill a gap in a faraway ecosystem that had lost its top predators.

Stretching metals at the atomic level allows researchers to create important materials for quantum, electronic, and spintronic applications      (via sciencedaily.com)     Original source 

A University of Minnesota Twin Cities-led team has developed a first-of-its-kind breakthrough method that makes it easier to create high-quality metal oxide films that are important for various next generation applications such as quantum computing and microelectronics.

Out of the frying pan: Coyotes, bobcats move into human-inhabited areas to avoid apex predators -- only to be killed by people      (via sciencedaily.com)     Original source 

Conservationists have argued that the presence of wolves and other apex predators, so named because they have no known predators aside from people, can help keep smaller predator species in check. New research shows that in Washington state, the presence of two apex predators -- wolves and cougars -- does indeed help keep populations of two smaller predators in check. But by and large the apex predators were not killing and eating the smaller predators, known as mesopredators. Instead, they drove the two mesopredator species -- bobcats and coyotes -- into areas with higher levels of human activity. And people were finishing the job.

Uncovering universal physics in the dynamics of a quantum system      (via sciencedaily.com)     Original source 

New experiments using one-dimensional gases of ultra-cold atoms reveal a universality in how quantum systems composed of many particles change over time following a large influx of energy that throws the system out of equilibrium.

Curved spacetime in a quantum simulator      (via sciencedaily.com)     Original source 

The connection between quantum physics and the theory of relativity is extremely hard to study. But now, scientists have set up a model system, which can help: Quantum particles can be tuned in such a way that the results can be translated into information about other systems, which are much harder to observe. This kind of 'quantum simulator' works very well and can lead to new insights about the nature of relativity and quantum physics.

Is it an ant? Is it a plant? No, it's a spider!      (via sciencedaily.com)     Original source 

A species of tiny, colorful jumping spider employs two lines of defense to avoid being eaten: camouflaging with plants and walking like an ant. Researchers report that this combination of camouflage and movement mimicry helps the spiders evade spider-eating spiders but does not deter hungry praying mantises.

Jaw shapes of 90 shark species show: Evolution driven by habitat      (via sciencedaily.com)     Original source 

Researchers investigated how the jaw shape of sharks has changed over the course of evolution. Their conclusion: in the most widespread shark species, the jaws show relatively little variation in shape over millions of years; most variable jaws were found for deep-sea sharks.

Crushed clams, roaming rays: Acoustic tags reveal predator interactions      (via sciencedaily.com)     Original source 

Inspired by clam fishermen reports, researchers used passive acoustic telemetry to gauge the interactions between two highly mobile rays. They monitored the tagged rays in the wild over two years to see how often and when they visited clam leases, designated underwater locations used to produce hard clams of all sizes from littlenecks to chowders. Results provide both good news and bad news for clammers. Rays spent even more time in these clam lease sites than clammers reported or suspected, but it's not necessarily where they prefer hanging out.

Most species, including humans, who experience early life adversity suffer as adults. How are gorillas different?      (via sciencedaily.com)     Original source 

There's something most species -- from baboons to humans to horses -- have in common: When they suffer serious adversity early in life, they're more likely to experience hardship later on in life.

Researchers have identified novel van der Waals (vdW) magnets using cutting-edge tools in artificial intelligence (AI). In particular, the team identified transition metal halide vdW materials with large magnetic moments that are predicted to be chemically stable using semi-supervised learning. These two-dimensional (2D) vdW magnets have potential applications in data storage, spintronics, and even quantum computing.
