Scientists have long known that dopamine helps the brain learn from rewards, but a new computational model shows how for people with schizophrenia this learning system can break down and simultaneously produce two very different symptoms — delusions and a loss of motivation.

Scientists in Sweden have for the first time created a fully wheat-based gel made entirely from wheat bran fiber and wheat gluten protein—an advance that could turn one of the grain industry’s least valued by products into a nutritious, sustainable ingredient in food products.

A new study revisits a century-old question about how turbulence starts. The findings could potentially influence not only aircraft engineering but even design of mechanical heart valves, and treatment of heart disease. Computer simulations at Stockholm’s KTH Royal Institute of Technology indicate that very small vortices may create increasingly larger swirls of flow—the opposite of the traditional view of how energy is transferred in turbulence.

The Baltic Sea is one of the world's most oxygen-depleted major bodies of water. The reason is excessive concentrations of phosphorus, an element essential for life—and an important ingredient in fertilizer. New research shows a way to possibly convert this problem into a resource that reduces Europe's dependency on phosphate mining while revitalizing the Baltic ecosystem.

Rail commuters in cold climates like Sweden’s are all too familiar with winter train delays and cancellations. The culprit is usually rail switches that freeze up or clog with snow even though they’re heated. A new study offers a more affordable and sustainable solution to keep these crucial, track-moving components in working order.

What would happen if all the plastic in your home disappeared overnight? A Swedish family found out by volunteering for one month of near-total plastic withdrawal, in an experiment conducted by researchers at KTH Royal Institute of Technology.

Recent research in Sweden and Finland shows how used concrete’s lifespan can be extended another 50 to 100 years when incorporated into new construction.

Safer operation, better fuel efficiency and lower waste mark lead-cooled nuclear power as a potentially dramatic shift from the water-cooled nuclear stations the world has relied on since the mid 20th century. A recent Swedish study casts new light on how to avoid corrosion in the steel used to build these next-generation nuclear facilities.

Polyester and a host of other plastic products could potentially be manufactured with non-toxic and sustainable BPA alternatives identified in a multidisciplinary study published today by researchers in Sweden.

A recent advance in the science of hydrogen fuel production could enable higher output and more sustainable production of this renewable energy source, researchers with Stockholm’s KTH Royal Institute of Technology report.

Cancer-fighting antibody drugs are designed to penetrate tumor cells and release a lethal payload deep within, but too often they don’t make it that far. A new study shows how this Trojan Horse strategy works better by exploiting calcium differences outside and inside cells.

A treatment that could protect premature babies from brain damage showed promise in a recent study in Sweden. Using a first-of-its-kind prenatal brain model created with human cells, researchers observed new details about the effects of cerebral hemorrhages on stem cells during premature birth. And they successfully tested an antidote that reduced the damage.

New research has produced a “blueprint” revealing how the human heart is built during prenatal development. It offers insights that could lead to improved prenatal care and new treatments for heart defects, such as holes between heart chambers or deformities of the heart valves.

Commuters trying to beat the clock account for nearly one third of shared electric scooter trips on a typical workday morning, recent research indicates. But reliance on these vehicles can be dampened when cities don’t provide enough parking near transit hubs, according to a new study.

A new study has mapped the distinct molecular “fingerprints” that 59 diseases leave in an individual’s blood protein – which would enable blood tests to discern troubling signs from those that are more common.

A new study reveals insights into the "antennae" - or primary cilia - that human cells use for signal processing. This atlas of human cilia may contribute to a better understanding of a range of genetic disorders.

A new diagnostic method would confirm sepsis infections earlier, cutting critical hours in the “race against time” to save patients’ lives.

Economic growth in developed countries can lead to more violent crime if an income gap between wealthy and poor citizens doesn’t narrow, according to a recent study.

Can AI do humor? A new study suggests artificial intelligence can create internet memes as funny as those made by humans. But when it comes to gags that truly connect with viewers, people still have the edge.

Faced with uncertain supply and soaring prices for rare earth minerals, electric vehicle manufacturers could nevertheless reduce their material demands by nearly 15 percent by remanufacturing and reusing components, a recent study shows.
