Schizophrenia is a serious mental disorder that affects around 1% of the world's population. Researchers have identified a deficit in contrast perception in people with schizophrenia. According to a review of more than 600 studies, these patients have an impaired ability to see differences in light intensity between adjacent areas, which allows us to identify shapes, textures and details in the environment.

A new one-minute video game is able to accurately and efficiently identify children with autism from those who have ADHD or are neurotypical.

A new study finds that prompts do a good job of getting drivers to engage with their environment and take over control of the vehicle when necessary while using partially automated driving systems -- with one exception. If drivers are deeply distracted, these system-generated prompts have little or no effect.

Researchers have developed two simple, easy-to-deliver sessions to improve the wellbeing of staff in pediatric critical care (PCC) units in UK hospitals.

Mites who hitchhike on the beaks of hummingbirds use a surprising method to help them on their journey: electricity. These hummingbird flower mites feed on nectar and live within specific flowers for their species. When it is time to seek out a new flower, they hitch a ride via hummingbirds, but for years researchers have not been sure exactly how these tiny, crawling arachnids quickly disembark at the right flower. Researchers are now closer to answering these questions.

A team of stem cell scientists have successfully used embryonic stem cell engineering to create a bi-paternal mouse -- a mouse with two male parents -- that lived until adulthood. Their results describe how targeting a particular set of genes involved in reproduction allowed the researchers to overcome previously insurmountable challenges in unisexual reproduction in mammals.

The fact that the cold, dry Mars of today had flowing rivers and lakes several billion years ago has puzzled scientists for decades. Now, researchers think they have a good explanation for a warmer, wetter ancient Mars. Building on prior theories describing the Mars of yore as a hot again, cold again place, a team has determined the chemical mechanisms by which ancient Mars was able to sustain enough warmth in its early days to host water, and possibly life.

The findings offer fresh insight into the remarkable capacity and accuracy of human hearing.

The dwarf planet is a bizarre, cryovolcanic world. However, the organic deposits discovered on its surface so far are unlikely to originate from its interior. The organic material found in a few areas on the surface of dwarf planet Ceres is probably of exogenic origin. Impacting asteroids from the outer asteroid belt may have brought it with them.

Proteins, the pillars of cellular function, often assemble into 'complexes' to fulfill their functions. A study reveals why this assembly often begins during the very process of protein synthesis or 'birth'. These early interactions involve proteins whose stability depends on their association. They can be compared to a couple in which each partner supports the other. This model paves the way for new strategies to understand and correct assembly errors, which are often associated with pathologies, including neurodegenerative disorders and certain cancers.

Biologists have identified important components and mechanisms of the molecular machinery that transmits information about a pathogen encounter within the plant organism.

Dating key tectonic events in Japan's geological history has long been often challenging due to poor microfossil preservation from intense heat due to metamorphism. Researchers tackled this by using Re--Os isotope geochronology on Besshi-type volcanogenic massive sulfide deposits (Makimine and Shimokawa deposits) associated with sediment-covered mid-ocean ridges. Their findings revealed the timing of ridge subduction -- when one tectonic plate was forced beneath another -- a process that shaped Japan's landscape and provided new insights into its geological evolution.

Ice nucleating particles as a kind of aerosols have a significant impact on the Arctic climate by promoting the formation of ice clouds at a temperature above -- 38 degrees Celsius. Wildfires in mid-latitudinal areas are a major source of these aerosols. However, a direct observation of wildfire-emitted aerosols facilitating ice cloud formation has never been documented. Now, using field and climate data, scientists have linked aerosols emitted by Canadian wildfires in 2023 to the formation of ice clouds over the Arctic Ocean.

Lithium-air batteries have the potential to outstrip conventional lithium-ion batteries by storing significantly more energy at the same weight. However, their high-performance values have thus far remained theoretical, and their lifespan remains too short. A team has now proposed addition of a soluble catalyst to the electrolyte. It acts as a redox mediator that facilitates charge transport and counteracts passivation of the electrodes.
