How to identify heat-stressed corals
Researchers have found a novel way to identify heat-stressed corals, which could help scientists pinpoint the coral species that need protection from warming ocean waters linked to climate change, according to a Rutgers-led study.

Spontaneous robot dances highlight a new kind of order in active matter
Researchers have proposed a new principle by which active matter systems can spontaneously order, without need for higher level instructions or even programmed interaction among the agents. And they have demonstrated this principle in a variety of systems, including groups of periodically shape-changing robots called "smarticles."

Controlling the nanoscale structure of membranes is key for clean water, researchers find
A desalination membrane acts as a filter for salty water: push the water through the membrane, get clean water suitable for agriculture, energy production and even drinking. The process seems simple enough, but it contains complex intricacies that have baffled scientists for decades -- until now. Researchers from Penn State, The University of Texas at Austin, Iowa State University, Dow Chemical Company and DuPont Water Solutions published a key finding in understanding how membranes actually filter minerals from water, online today (Dec. 31) in Science.

The map of nuclear deformation takes the form of a mountain landscape
Until recently, scientists believed that only very massive nuclei could have excited zero-spin states of increased stability with a significantly deformed shape. Meanwhile, an international team of researchers from Romania, France, Italy, the USA and Poland showed in their latest article that such states also exist in much lighter nickel nuclei. Positive verification of the theoretical model used in these experiments allows describing the properties of nuclei unavailable in Earth laboratories.

Breaking bad: how shattered chromosomes make cancer cells drug-resistant
UC San Diego and Ludwig Cancer Research scientists describe how a phenomenon known as "chromothripsis" breaks up chromosomes, which then reassemble in ways that ultimately promote cancer cell growth.

Research reveals compromised transfer of SARS-CoV-2-specific antibodies through placenta
Lower than expected levels of protective SARS-CoV-2 antibodies pass through the placenta from mothers who are infected in the third trimester with the virus that causes COVID-19. This low level of transfer from mother to fetus may be caused by altered attachments of carbohydrates to the SARS-CoV-2-specific antibodies.

Bait and switch
Seafood is the world's most highly traded food commodity, and reports of seafood mislabeling have increased over the past decade. However, proof of the environmental effects of mislabeled seafood has been scant as has research. So, Arizona State University researcher Kailin Kroetz and her colleagues analyzed the impact of seafood mislabeling on marine population health, fishery management effectiveness, and habitats and ecosystems in the United States, the world's largest seafood importer.

Mouse-controlled mouse helps researchers understand intentional control
Researchers at the Sainsbury Wellcome Centre have devised a brain machine interface (BMI) that allows mice to learn to guide a cursor using only their brain activity. By monitoring this mouse-controlled mouse moving to a target location to receive a reward, the researchers were able to study how the brain represents intentional control.
This research was supported by the European Research Council, Swiss National Science Foundation, Gatsby Charitable Foundation, Wellcome, EMBO Long-term Fellowship, HFSP Postdoctoral Fellowship, and the Branco Weiss-Society in Science grant.

How roundworms decide the time is right
The roundworm C. elegans matches its development to the amount of food in its environment. It uses a protein called BLMP-1 to open up a large set of developmental genes, priming them to turn on when food is plentiful. Humans have a protein with a similar function that is known to be overactive in some blood cancers.

Review on functional hydrogel coatings
Hydrogel-coated substrates combine the merits of both the substrates and hydrogels, enabling new functions and applications. Typical applications of hydrogel coatings can be found in both medical and non-medical areas, such as soft devices and robotics, invasive medical devices and implants. The emerging topic of functional hydrogel coatings are reviewed from three aspects: functions and applications of hydrogel coatings, methods of preparing hydrogel coatings with strong adhesion, and tests to evaluate the adhesion.

A groggy climate giant: subsea permafrost is still waking up after 12,000 years
After the Last Glacial Maximum some 14,000 years ago, rising temperature melted glaciers and ice caps worldwide. Over thousands of years, sea levels rose by more than 400 feet (130 meters).

Deep, slow-slip action may direct largest earthquakes and their tsunamis
Megathrust earthquakes and subsequent tsunamis that originate in subduction zones like Cascadia -- Vancouver Island, Canada, to northern California -- are some of the most severe natural disasters in the world. Now a team of geoscientists thinks the key to understanding some of these destructive events may lie in the deep, gradual slow-slip behaviors beneath the subduction zones. This information might help in planning for future earthquakes in the area.

Brain stem cells divide over months
For the first time, scientists at the University of Zurich have been able to observe the way stem cells in the adult brains of mice divide over the course of months to create new nerve cells. Their study shows that brain stem cells are active over a long period, and thus provides new insights that will feed into stem cell research.

Regulating off-centering distortion maximizes photoluminescence in halide perovskites
In work published in the National Science Review (nwaa288), a team at HPSTAR led by Dr. Xujie Lü applied high pressure to tune the remarkable photoluminescence (PL) properties in halide perovskites. For the first time, they reveal a universal relationship whereby regulating the level of off-centering distortion (towards 0.2) can achieve optimal PL performance.

Antibiotics for C-sections effective after umbilical cord clamped
Antibiotics for cesarean section births are just as effective when they're given after the umbilical cord is clamped as before clamping - the current practice - and could benefit newborns' developing microbiomes, according to Rutgers co-authored research. The study, by far the largest of its kind and published in the journal Antimicrobial Resistance & Infection Control, challenges current recommendations for antibiotic use. Administering antibiotics after clamping does not increase the risk of infection at the site of C-section incisions, the study concludes.
