Underwater drones adapted to cold Nordic waters, and sensors that listen to the sounds of fish eating. These are some of the AI solutions that could give European sea farmers a boost to compete globally. Researcher Fredrik Gröndahl explains how maching learning is being developed take on operational challenges and reduce costs in aquaculture, particularly in inaccessible waters far offshore.

One key to making portable devices more compact and energy efficient lies in the precise nanoscale form of energy-storing capacitors. Researchers in Sweden report they've cracked the challenge with a unique 3D printing method.

Researchers demonstrated a way to speed up—and potentially scale up—the process for separating particles in fluids, which can be used for studying microplastics in drinking water or even analyzing cancer cells from blood.

A group of leading academics are calling for the UN Sustainable Development Goals to be extended past their 2030 target date and updated with consideration for the impact of artificial intelligence (AI), and with more input from communities affected by the goals, among other recommendations.

In a first for communications, researchers in Sweden 3D printed silica glass micro-optics on the tips of optic fibers—surfaces as small as the cross section of a human hair. The advance could enable faster internet and improved connectivity, as well as innovations like smaller sensors and imaging systems.

Climate change is transforming dust storms—a natural phenomenon in the Middle East—into a more frequent and widespread threat to health and economies throughout the region, a new study shows.

Researchers in Sweden say they have improved on a technique for converting regular skin cells into neural stem cells—an advance which they say helps close the gap for accessible personalized cell-based therapies for Alzheimer's and Parkinson's.

Typically viewed as unrelated problems, global warming and plastic pollution are instead inextricably trapped in a “vicious circle” where one feeds the other, researchers in Sweden report in Nature Communications. The mutually-reinforcing relationship escalates global warming, the degradation of materials, plastic waste and the leaching of toxic chemicals into the biosphere.

Researchers in Sweden unveiled a new concept for producing hydrogen energy more efficiently, splitting water into oxygen and hydrogen without the dangerous risk of mixing the two gases.

Aerodynamic drag is a major contributor to global emissions. Here’s how a recent development in deep learning can help reduce it.

In order to prevent power grid failure in a society where electrification is supplied increasingly by variable sources like solar and wind, researchers in Sweden report the development of artificial intelligence algorithms intended to react swiftly when the network’s voltage balance is threatened.

The speed of innovation in bioelectronics and critical sensors gets a new boost with the unveiling of a technique for fast-prototyping of devices.

With the aim to strengthen its cyber security skills supply and research, Sweden inaugurated its new Cybercampus Sweden yesterday. The national initiative was formally launched in a ceremony at KTH Royal Institute of Technology in Stockholm with Civil Defense Minister Carl-Oskar Bohlin and Education Minister Mats Persson in attendance.

Materials and objects could take on different shapes by themselves through a method developed at KTH Royal Institute of Technology. Breakthrough tests showed how microscale melting and cooling of a wide range of materials—such as plastics and metals—can be manipulated to reorganize their mass and form new shapes.

One reason getting rid of bed bugs is such an ordeal is that these pests have to be lured out of their hiding places by using people as bait. Two students at KTH Royal Institute of Technology are out to stop bed bugs in their tracks with a new device that would take the pain out of the process.

Wood is the source for a brick-breaking mini robotic muscle material developed by researchers in Sweden and Germany. The material — a specially-developed hydrogel — can shape-shift, expand and contract on demand when controlled with electronic impulses of less than 1 volt.

Researchers in Sweden have developed a microscale device for implantation in the eye, which presents new opportunities for cell-based treatment of diabetes and other diseases.

STOCKHOLM (September 7, 2023) KTH Royal Institute of Technology is to play a central role in developing Sweden's cyber defense education and research, under the government budget proposal announced yesterday for a new Cybercampus Sweden.

Dozens of European cities could reach net zero carbon emissions over the next 10 years by incorporating nature into their infrastructure, according to a new study.

When startled, animals are driven by the need for survival to think fast. A new study shows this principle may already be wired in the way the brain processes sensory information.
