Neoliberals are most receptive to political tricks, study finds

Do we fall for political tricks—when politicians tell us things that seem completely meaningless? Social psychologists of the University of Amsterdam tested how people respond to vague and meaningless statements like "To politically lead the people means to always fight for them" and "For better and stronger Gonfel!" (a fictitious country). They find that right-wing people, and especially...

Project counts down Ariel exoplanet targets

Details of the orbits of 450 candidate exoplanet targets of the European Space Agency's Ariel space mission have been presented this week at the Europlanet Science Congress (EPSC) 2022, and submitted for publication in the Astrophysical Journal Supplement Series. The study, coordinated by the ExoClock project, has been co-authored by 217 professional and amateur astronomers, as well as university...

Mutation in key molecules could stop gonorrhea infection

Creating a mutation that inhibits how the bacterial pathogen Neisseria gonorrhoeae causes gonorrhea, a common sexually transmitted infection, could offer a new way to prevent and treat the disease, according to researchers in the Institute for Biomedical Sciences at Georgia State University.

Tracking the origin of southern California's latest invasive pest

In 2012, a crop of California's most prized ornamental trees was overrun by an invisible invader. The growing shoots of coral beans—the official city tree of Los Angeles—began wilting and falling away, revealing stems that had been hollowed out from the inside by the caterpillars of Erythrina stem borer moths.

The carp virus that taught researchers about immunology

One of the fascinating aspects of scientific research is certainly the serendipity that comes with it, which is something the team of Prof. Alain Vanderplasschen, virologist and immunologist at the FARAH (Faculty of Veterinary Medicine) of the University of Liège can only agree with. His team has just published in Nucleic Acids Research the results of ten years of research on the study of an...

Scientists use modified silk proteins to create new nonstick surfaces

Researchers at Tufts University have developed a method to make silk-based materials that refuse to stick to water, or almost anything else containing water for that matter. In fact, the modified silk, which can be molded into forms like plastic, or coated onto surfaces as a film, has non-stick properties that surpass those of nonstick surfaces typically used on cookware, and it could see...

Higher temperatures make it difficult for fig tree pollinators

Researchers from Uppsala University and elsewhere have been studying the effect of rising temperatures on the lifespan of pollinating fig wasps. The findings show that the wasps lived much shorter lives at high temperatures, which would make it difficult for them to travel the long distances between the trees they pollinate.

Developing conductive and electrocatalytic mediators in Li-S batteries

Lithium sulfide (Li-S) batteries are considered a promising and efficient energy storage system because of their high energy density (2600 Wh kg-1) and low sulfur material cost. However, numerous obstacles to the practical implementation of Li–S batteries remain, including low sulfur conductivity, the shuttle effect, and the requirement for an adequate volume change (80%) of sulfur during...

A quadruple increase in carbon dioxide over East Asia causes changes in both fast and slow cloud responses

Extreme climate warming has been shown to change how cloud cover behaves throughout East Asia (EA). Recent research suggests that in a warmer climate with greater amounts of CO2 in the atmosphere, slow cloud responses to meteorological mechanisms can cause a cooling effect over certain regions of EA. However, in some areas within Asia, fast cloud responses may have the opposite effect. This new...

When monkeys use the forest as a pharmacy

Have you ever seen your cat or dog eating grass? They do so because it can help their digestion, and many wild species use natural substances to prevent and control diseases or to repel parasites. This is called "zoopharmacognosy" or, more commonly, animal self-medication.

The expansion of capitalism led to a deterioration in human welfare, according to new study

Far from reducing extreme poverty, the expansion of capitalism from the 16th century onward was associated with a dramatic deterioration in human welfare. This is according to a study carried out by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) in collaboration with Macquarie University, Australia, which shows that this new economic...
