The chemical reaction to produce hydrogen from water is several times more effective when using a combination of new materials in three layers, according to researchers at Linköping University in Sweden. Hydrogen produced from water is a promising renewable energy source – especially if the hydrogen is produced using sunlight. The production of new petrol…

A single pellet of recycled plastic can contain over 80 different chemicals. A new study with researchers from University of Gothenburg and Leipzig shows that recycled polyethylene plastic can leach chemicals into water causing impacts in the hormone systems and lipid metabolism of zebrafish larvae. The plastic pollution crisis has reached global levels, threatening both…

Understanding how the universe transitioned from darkness to light with the formation of the first stars and galaxies is a key turning point in the universe’s development, known as the Cosmic Dawn. However, even with the most powerful telescopes, we can’t directly observe these earliest stars, so determining their properties is one of the biggest…

A team of researchers at Rice University have discovered a surprisingly simple method for vastly improving the stability of electrochemical devices that convert carbon dioxide into useful fuels and chemicals, and it involves nothing more than sending the CO2 through an acid bubbler. Their study, published in Science, addresses a major bottleneck in the performance…

Scientists at the USC Leonard Davis School of Gerontology have discovered a key connection between high levels of iron in the brain and increased cell damage in people who have both Down syndrome and Alzheimer’s disease. In the study, researchers found that the brains of people diagnosed with Down syndrome and Alzheimer’s disease (DSAD) had…

The idea seems futuristic: At ETH Zurich, various disciplines are working together to combine conventional materials with bacteria, algae and fungi. The common goal: to create living materials that acquire useful properties thanks to the metabolism of microorganisms — “such as the ability to bind CO2 from the air by means of photosynthesis,” says Mark…

To reduce greenhouse gas emissions and combat climate change, the world urgently needs clean and renewable energy sources. Hydrogen is one such clean energy source that has zero carbon content and stores much more energy by weight than gasoline. One promising method to produce hydrogen is electrochemical water-splitting, a process that uses electricity to break…

Peatlands across the Arctic are expanding as the climate warms, new research shows. Scientists used satellite data, drones and on-the-ground observations to assess the edges of existing peatlands (waterlogged ecosystems that store vast amounts of carbon). The study – led by the University of Exeter – found peatlands in the European and Canadian Arctic have…

Bacteria of the genus Pandoraea have not been studied much to date. Their name is reminiscent of Pandora’s box from Greek mythology, which is a symbol of uncontrollable dangers. “We have been working with an antibiotic-resistant bacterium,” says Elena Herzog. She is the first author of the publication and works as a doctoral researcher in…

No matter which questions we ask an AI, the model will come up with an answer. To produce this information – regardless of whether than answer is correct or not – the model uses tokens. Tokens are words or parts of words that are converted into a string of numbers that can be processed by…

Nematodes are the most abundant animal on earth, but when times get tough, these tiny worms have a hard time moving up and out. So, they play to the strength of their clade. If food runs out and competition turns fierce, they slither towards their numerous kin. They climb onto each other and over one…

New research led by scientists at the American Museum of Natural History sheds light on the ancient origins of biofluorescence in fishes and the range of brilliant colors involved in this biological phenomenon. Detailed in two complementary studies recently published in Nature Communications and PLOS One, the findings suggest that biofluorescence dates back at least…

A USC-led research team has created a series of supercomputer-simulated twins of our Milky Way galaxy — which could help scientists unlock new answers about one of the biggest mysteries in the universe: dark matter, the invisible substance that makes up about 85% of all matter in existence. The research was led by cosmologist Vera…

An international team of scientists has published a new report that moves towards a better understanding of the behaviour of some of the heaviest particles in the universe under extreme conditions, which are similar to those just after the big bang. The paper, published in the journal Physics Reports, is signed by physicists Juan M….

As a child, I was fascinated by reports and documentaries about field research and often wondered what it took to be there and what kind of knowledge was being produced. Later, as an ecologist, I felt the need for approaches that better connected scientific research with real-world contexts. I became especially interested in perspectives that…

Air pollution causes health problems and is attributable to some 50,000 annual deaths in the United States, but not all air pollutants pack the same punch. Scientists have tracked the scope of “PM 2.5” pollution over decades. PM 2.5 is a size of “particulate matter” that is less than 2.5 microns in diameter. But less…

An international team of astronomers has trained a neural network with millions of synthetic simulations and artificial intelligence (AI) to tease out new cosmic curiosities about black holes, revealing the one at the center of our Milky Way is spinning at nearly top speed. These large ensembles of simulations were generated by throughput computing capabilities…

New research led by Dr. James De Buizer at the SETI Institute and Dr. Wanggi Lim at IPAC at Caltech revealed surprising results about the rate at which high-mass stars form in the Galactic Center of the Milky Way. The researchers based their study primarily on observations from NASA’s now-retired SOFIA airborne observatory, focusing on…

In a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions — a feat that many scientists didn’t think was possible. The device, a new type of atom “interferometer,” could one day help people navigate submarines,…

To allow studying the genetic causes of autism spectrum disorder, a Kobe University research team created a bank of 63 mouse embryonic stem cell lines containing the mutations most strongly associated with the disorder. The achievement was made possible by developing a new and more efficient method for changing the genome of embryonic stem cells….

A new study to be presented at the SLEEP 2025 annual meeting found that teens who get moderate — but not excessive — catch-up sleep on weekends have fewer symptoms of anxiety. Results show that teens who got up to two more hours of sleep on weekends than on weekdays exhibited fewer anxiety symptoms compared…
