In-plane antiferromagnets host a rich class of particle-like spin textures

Compared with the chiral spin textures in ferromagnets, their antiferromagnetic counterparts can be manipulated by spin currents with a more direct approach due to the absence of the skyrmion Hall effect, and much lower power consumption, as well. So far, most research has focused on isolated excitation in perpendicular antiferromagnetic spin systems, for example, skyrmion solitons. Meanwhile, the characteristics and the related physics of its in-plane analog, the bimeron, remain elusive.

Dogs at war with fungus

The fungus that some dogs carry in their nose evolves within the dog's nose. The genetic changes indicate adaptation of the fungus to the dog. That's also of importance for humans, since infection with this fungus can be deadly. Researchers of Utrecht University gained these new insights in research on natural infections of dogs that came with an inflammation at the veterinarian. The study thus also shows that studying natural infections is an alternative to experiments with laboratory animals. They publish their findings 12 November in Nature Biofilms and Microbiomes.

Model comparison adds more value in simulating extreme temperatures in China

Against the background of global warming, more intense and frequent heat waves have brought huge impacts on society and the natural world. As such, the characteristics of extreme temperature changes in the future have become a key concern of the climate change community. Climate models have provided an avenue for studying the possible changes in extreme temperatures in the future. The World Climate Research Program (WCRP) established the Coupled Model Intercomparison Project (CMIP), which is devoted to providing standardized climate simulation outputs for intercomparison purposes. However, there are still large uncertainties in the simulation results of existing models. Particularly, when simulating temperature extremes in China, the differences between the models of the previous CMIP phase (CMIP5) and their more advanced versions in the current phase (CMIP6) is an important question.

Losing the American Dream

As many Americans struggle to pay their bills, keeping up with mortgage payments can be daunting with the risk of losing one's home. The challenges to retain a home are stratified along racial differences. Black homeowners are twice as likely to lose their homes and transition back to renting than white homeowners, according to a recent Dartmouth-led study published in Demography . African American owners exit their homes at a rate of 10 percent compared with whites' exit rate of five percent. These racial disparities in the loss of homeownership are due in part to Black homeowners having less access to wealth from extended family and higher rates of poverty across family networks.

Decrease in fossil-fuel carbon dioxide emissions due to COVID-19 detected by atmospheric observations

Atmospheric observations at Hateruma Island, Japan, successfully detected the decrease in fossil-fuel CO2 emissions in China associated with the COVID-19 outbreak. The weather in Hateruma island is frequently influenced by the northwest monsoon traveling over China, which carries the emission signals of air pollutants. The observed ratios of CO2 and CH4 variabilities showed a significant decrease during February-March 2020, corresponding to about a 30% decrease in China's fossil-fuel CO2 emissions, according to a chemistry-transport model simulation.

The biggest trees capture the most carbon: Large trees dominate carbon storage in forests

Older, large-diameter trees have been shown to store disproportionally massive amounts of carbon compared to smaller trees, highlighting their importance in mitigating climate change, according to a new study in Frontiers in Forests and Global Change. Researchers examined the aboveground carbon storage of large-diameter trees (>21 inches or >53.3 cm) on National Forest lands within Oregon and Washington. They found that despite only accounting for 3% of the total number of trees on the studied plots, large trees stored 42% of the total above-ground carbon within these forest ecosystems. This study is among the first of its kind to report how a proposed policy could affect carbon storage in forest ecosystems, potentially weakening protections for large-diameter trees and contributing to huge releases of carbon dioxide to the atmosphere in the face of a changing climate.

'Helper' ambrosia beetles share reproduction with their mother

Fungus farming is a fascinating symbiosis that has evolved multiple times in social insects: once in ants, once in termites, and several times in weevils (beetles) from the subfamilies Scolytinae and Platypodinae. The behavior of these "ambrosia beetles"—over 3,000 species—is poorly known, because they live inside galleries in wood, making observation hard. Here, a study focuses for the first time on the division of labor within colonies of ambrosia beetles. The author shows that in Xyleborus affinis, unlike in ants and termites, social behavior such as brood and fungus care is mostly by fertile "helper" females who reproduce alongside their mother, the colony foundress. He also shows that a specialized fungus in the genus Raffaelea is probably the only food source for the larvae.

Decaying jellyfish blooms can cause temporary changes to water column food webs

Decaying jellyfish blooms fuel the rapid growth of just a few strains of seawater bacteria, effectively keeping this organic material within the water column food web, reveals a new study published in Frontiers in Microbiology. This research furthers our understanding of how marine ecosystems are impacted by jellyfish blooms, which have been observed to be happening on a more frequent basis.

Male fin whales surprise scientists by swapping songs

Until now, scientists believed the male fin whale sings just one song pattern, which is unique to the males in his particular group—but new research has blown this theory out of the water. The study, published in Frontiers in Marine Science, suggests that these endangered deep-sea giants actually sing multiple different songs, which may spread to different parts of the ocean through migrating individuals. Understanding the complexity of fin whale song provides new insights into how their populations move and change over time, helping efforts to better protect and manage the world's second largest mammal.

Phytoplasma effector proteins devastate host plants through molecular mimicry

Phytoplasma are a type of bacteria that live within the cells and cause devastating diseases with damaging effects. For example, in many cases plants infected with phytoplasma are no longer able to develop flowers. These plants have actually been described as "zombies," since they allow the reproduction of phytoplasma but are unable to reproduce themselves anymore. A group of biologists based at Friedrich Schiller University and the Fritz Lipmann Institute in Germany are working to help better understand exactly how phytoplasma cells bring about the so-called zombification of plants.

Vampire bats social distance when they get sick

History shows that societies collapse when leaders undermine social contracts

All good things must come to an end. Whether societies are ruled by ruthless dictators or more well-meaning representatives, they fall apart in time, with different degrees of severity. In a new paper, anthropologists examined a broad, global sample of 30 pre-modern societies. They found that when "good" governments—ones that provided goods and services for their people and did not starkly concentrate wealth and power—fell apart, they broke down more intensely than collapsing despotic regimes. And the researchers found a common thread in the collapse of good governments: leaders who undermined and broke from upholding core societal principles, morals, and ideals.
