While social media platforms are the primary source of political information for a growing number of people, a majority of Twitter users do not follow either members of Congress, their president or news media, a new study suggests. They are much more likely to follow Tom Hanks or Katie Perry than an elected official.

"Without further investments in the bioeconomy, the net zero emission target will not be met." Data issued from the EU project Biomonitor point out gaps in the Green Deal and suggest speeding up procedures states, "New technologies must be fostered but length and complexity of the European approval process risk discouraging the investors."

Research by Texas A&M AgriLife Research scientists in the Texas A&M Department of Entomology showed a common ant species undergoes physiological and behavioral changes in unnatural settings.

Researchers from Nagoya University in central Japan have published a study in the Journal of Materials Chemistry C on a pressure-sensitive material, known as fluorenylidene-acridane (FA). Their research has potential applications for technologies related to pressure sensing, recording, and display devices.

A research team led by Prof. Sun Weidong from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS) and their collaborators from Curtin University and Geological Survey of Western Australia have reported a remarkable mantle cooling event that records the onset of modern plate tectonics.

With a high energy density, Li-O2 batteries have become a state-of-the-art battery technology. Inside the Li-O2 battery, the generation and disintegration of the discharged product solid lithium peroxide (Li2O2) have a significant effect on the battery's performance. Previous research has shed little light on Li2O2 's form and distribution inside, leaving questions regarding the trend and contributing factor of internal Li2O2 's change in form and size unanswered.

A Newcastle University study has for the first time shown that machine learning can predict the biological properties of the most abundant enzyme on Earth—Rubisco.

Many people whose loved ones stayed behind in the pathway of Hurricane Ian are crowdsourcing rescue efforts as they grapple with the helplessness of waiting and not knowing.

Biophysicists from Skoltech, MIPT and their colleagues from the company Prostagnost have created a new technology for isolating extracellular vesicles (EV) from biological fluids. Studying vesicles is essential for the diagnosis and treatment of various diseases, including cancer. The new technique not only outperforms methods known to date in purity and yield of EVs, but also is simple, fast, inexpensive and can run on standard lab hardware. The research was published in the Journal of Extracellular Vesicles.

A large wingless wood-eating cockroach, unique to Australia's Lord Howe Island and thought extinct since the 1930s, has been rediscovered by a University of Sydney biology student.

Using fossil fuels causes large amounts of carbon dioxide (CO2) to be emitted, which is one of the major greenhouse gases responsible for global warming. The climate changes under increasing CO2 radiative forcing (called "CO2 ramp-up") have been widely projected using numerical experiments. For a carbon-neutral world, more studies have begun to focus on the regional climate responses under decreasing CO2 forcing from a high CO2 concentration to the pre-industrial level (called "CO2 ramp-down").

SUE the T. rex is one of the most complete, best-preserved Tyrannosaurus rex specimens ever found. That level of preservation helps reveal details about SUE's life. For instance, SUE lived to a ripe old age of about thirty-three, and in those years, suffered their fair share of injuries. SUE's most mysterious ailment might be the holes in their jawbone.

Potassium-ion batteries (PIBs) have been considered one of the most promising alternatives to lithium-ion batteries (LIBs) because of their competitive energy density with significantly low production costs. Moreover, alloy-type materials are expected to be the high-performance anode of PIBs owing to their intrinsic chemical stability and high theoretical specific capacity. Unfortunately, severe incompatibility between the active alloy-type materials and electrolytes, especially for the formation... Читать дальше...

"It is crucial that the revenues from CO2 pricing are returned, and in a targeted manner: Distributing them back in shotgun-mode is only the second-best solution," explains Martin Hänsel, an economist at PIK and lead author of a new study, which appeared in the Journal of Environmental Economics and Management.

A method to draw data in an area smaller than 10 nanometers has been proposed in a recent study published in Physical Review Letters

Why has the SARS-CoV-2 virus ravaged the global human population, but many other animal viruses haven't? Using nematode worms as a model, researchers at Penn State conducted a set of experiments to investigate the factors influencing the disease outcomes of virus spillover events. They found that the species of the host influences whether a virus will take off in a new population. For example, some species never get infected, while others become infected and readily transmit the virus to other individuals within the species.

A new study has found that hostile behaviors from "abusive" bosses can lead to co-workers adopting similar behavior, leading to a toxic atmosphere of insecurity and exhaustion in the workplace.

A long-term study led by primatologist Crickette Sanz at Washington University in St. Louis reveals the first evidence of lasting social relationships between chimpanzees and gorillas in the wild.

Soil antimicrobial resistance (AMR) is posing increasing health risks due to possible transmission to humans through direct contact and through the food chain. However, soil AMR studies have relied mostly on environmental DNA that could come from dead/dominant cells and extracellular DNA, leading to potential overestimation of AMR and associated risks because the vast majority of soil microbes are yet uncultured. Active antibiotic resistant bacteria (ARB) in soils play a critical role in driving AMR dissemination but are not well understood.

Blue-green algae (AKA cyanobacteria) have a superpower which likely helps them be highly successful as invaders of waterways. They have an extraordinary ability to store energy and nitrogen in their cells for times of need. But how exactly they do so remains only partly understood.

BGI Genomics, in collaboration with Southwest University, the State Key Laboratory of Silkworm Genome Biology, and other partners, has constructed a high-resolution pangenome dataset representing almost the entire genomic content in a silkworm.

Only 73 southern resident orcas that live along the coast of Oregon, Washington and British Columbia remain as of July 1, according to the latest census from the Center for Whale Research.

A study conducted by a joint team from Chinese Academy of Sciences used aberration-corrected transmission electron microscopy (TEM), Electron-energy loss spectroscopy (EELS) and scanning transmission electron microscopy (STEM) to examine the microstructures and chemical compositions at nano/atomic scales of 25 soil grains (1-3 μm in size) from lunar sample CE5C0400YJFM00507 (1.5 g).

Every time a new Hall effect is discovered, a wave of research is inspired. The first experiment on a new type of Hall effect, the layer Hall effect, had been reported by Xu's group at Harvard University. In the layer Hall effect, electrons from the top and bottom layers are deflected in opposite directions and were measured by applying an out-of-plane electric field to break the PT symmetry, where P and T represent inversion symmetry and time-reversal symmetry, respectively.

Call it "having their 'Pi' and buying too." A new study finds that consumers are more likely to make purchases during promotions tied to a special day, like Pi Day (March 14), than during regular holiday or non-distinctive day promotions.
