New research by the University of Stirling's Institute of Aquaculture could help improve mussel farming practices and lead to increased production.

A TU/e and Catalan Institute of Nanoscience and Nanotechnology-led collaboration involving researchers from around the world has the answer, and the why, and the results have been published in the journal Science Advances.

Are our bodies solid or liquid? We all know the convention—that solids maintain their shapes, while liquids fill the containers they're in. But often in the real world, those lines are blurred. Imagine walking on a beach. Sometimes the sand gives way under feet, deforming like a liquid, but when enough sand grains pack together, they can support weight like a solid surface.

Semiconductors are ubiquitous in modern technology, working to either enable or prevent the flow of electricity. In order to understand the potential of two-dimensional semiconductors for future computer and photovoltaic technologies, researchers from the Universities of Göttingen, Marburg and Cambridge investigated the bond that builds between the electrons and holes contained in these materials.

Researchers at the University of Helsinki have discovered a new mechanism of action between the nutrient adaptation of intestinal stem cells and aging. The finding may make a difference when seeking ways to maintain the functional capacity of the aging gut.

The Venosta Valley is located in South Tyrol, which is primarily associated with mountains and nature. In this region in the North of Italy, more than 7,000 apple growers produce 10% of all European apples. Conventional apple cultivation relies primarily on synthetic pesticides, which are applied by fan-assisted sprayers: insecticides to combat pests such as the codling moth and fungicides against fungal diseases that cause scabs on the fruit. This results in a high level of drift into the environment, especially in windy conditions.

Following the arrival of the first farmers in Scandinavia 5,900 years ago, the hunter-gatherer population was wiped out within a few generations, according to a new study from Lund University in Sweden, among others. The results, which are contrary to prevailing opinion, are based on DNA analysis of skeletons and teeth found in what is now Denmark.

Climate changes usually happen over long periods of time, but during the last glacial period, extreme fluctuations in temperature occurred within just a few years. Researchers at the University of Basel have now been able to prove the phenomenon also occurred during the penultimate glacial period.

Rochester researchers are uncovering the unexpected role of grain shape in the mixing of granular systems such as pharmaceuticals, cereal, and landslides.

About 10% of human-made mercury emissions into the atmosphere each year are the result of global deforestation, according to a new MIT study.

Researchers from Tokyo Metropolitan University have come up with a new way of rolling atomically thin sheets of atoms into "nanoscrolls." Their unique approach uses transition metal dichalcogenide sheets with a different composition on either side, realizing a tight roll that gives scrolls down to five nanometers in diameter at the center and micrometers in length. Control over nanostructure in these scrolls promises new developments in catalysis and photovoltaic devices.

By analyzing the images obtained with the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), astronomers have serendipitously discovered a new protoplanetary disk located some 800 light years away. The finding was reported in a paper published February 1 on the pre-print server arXiv.

It's well known that plants have a fine-tuned ability to sense changes in the season by how much daylight they're exposed to, yet scientists observed more than a century ago that plants sometimes grow during one season and flower in another. Most research in the decades since, however, has focused on seasonal flowering, leaving that classic observation unstudied.

Atomic clocks are a class of clocks that leverage resonance frequencies of atoms to keep time with high precision. While these clocks have become increasingly advanced and accurate over the years, existing versions might not best utilize the resources they rely on to keep time.

The concept of deadly mass extinctions wreaking destruction upon Earth's ecosystems millions of years ago is something that has fascinated the public and scientists alike for decades.

Excited nature lovers flocked to a tiny town from all across the state of Vermont last September, wildlife officials said. They all came to see one rare sight: a marbled godwit.

While NASA is rooting for SpaceX to achieve Starship success so it can land humans on the moon, the U.S. military has plans of their own for the massive rocket that could include launches from Florida's Space Coast.

For the first time in U.S. history, a federally listed endangered species has been reintroduced to the wild by the efforts of a lone state. Wolves in Colorado were not a mandate from Washington, D.C.; Coloradans voted for them.

Nancy Caruso sat on an island in the North Pacific Ocean just inches from an albatross and watched as the large black-and-white sea bird with a 12-foot wingspan added grass to its nest to cover up a precious 4-inch white egg.

A critical system of Atlantic Ocean currents may be approaching collapse, which scientists warn will have a dangerous impact on our global climate.

Wild weather has been roiling North America for the past few months, thanks in part to a strong El Niño that sent temperatures surging in 2023. The climate phenomenon fed atmospheric rivers drenching the West Coast and contributed to summer's extreme heat in the South and Midwest and fall's wet storms across the East.
