In a new study, an international team of academics have identified the most important questions that must be answered in order to advance the conservation and restoration of seagrass meadows in Europe.

A research team has picked a side in the "Snowball Earth" debate over the possible cause of planet-wide deep freeze events that occurred in the distant past. According to their new study, these so-called "Snowball" Earth periods, in which the planet's surface was covered in ice for thousands or even millions of years, could have been triggered abruptly by large asteroids that slammed into the Earth.

Ahead of International Day of Women and Girls in Science this Sunday, 11 February, The University of Warwick is shining the spotlight on a physicist who is developing new technology to advance the diagnosis and screening of skin cancers.

Some animals live in such remote and inaccessible regions of the globe that it is nearly impossible to study them in their natural habitats. Beaked whales, of which 24 species have been found so far, are among them: They live far from land and in deep oceanic waters, where they search for food at depths of 500 meters and more.

In writing a good online dating profile, the average love-seeker will likely fill it up with all the appealing qualities and interests that make them special. They paraglide and do hot yoga on the weekends, enjoy Riesling on the beach or seeing indie bands in basements, are a Libra with Scorpio rising, or have a dog or three kids or an iguana. There's one thing they routinely leave out, however: what they want to know about their potential partner.

A coating that can hide objects in plain sight, or an implant that behaves exactly like bone tissue—these extraordinary objects are already made from "metamaterials." Researchers from TU Delft have now developed an AI tool that not only can discover such extraordinary materials but also makes them fabrication-ready and durable. This makes it possible to create devices with unprecedented functionalities. They have published their findings in Advanced Materials.

Researchers have developed a sensor made from "frozen smoke" that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far beyond the sensitivity of most indoor air quality sensors.

This NASA/ESA Hubble Space Telescope image shows a densely packed field of stars laid upon a background of dust, gas, and light from more distant celestial objects. There are so many stars in this image's field of view that it may be a little tricky to discern that you are, in fact, looking at a galaxy.

In an online article published In Invasive Plant Science and Management, Justin D. Salva and Bethany A. Bradley performed and reported impact assessments on 104 plants most likely to expand with climate change into one or more Eastern U.S. States (Delaware, Kentucky, Maryland, New Jersey, Ohio, Pennsylvania, Virginia, and/or West Virginia) by 2050.

Relatively simple adjustments can reduce nitrogen losses on dairy farms in peatland areas. That's the conclusion of the Ph.D. research by Leiden environmental scientist Jeroen Pijlman at the Louis Bolk Institute. Protein-poor grass species and narrow-leaved plantain in the grassland can limit nitrogen loss without decreasing milk yield. The research also demonstrates potential for the wet cultivation of bulrush.

For the first time since 1972, NASA is putting science experiments on the moon in 2024. And thanks to new technologies and public-private partnerships, these projects will open up new realms of scientific possibility. As parts of several projects launching this year, teams of scientists, including myself, will conduct radio astronomy from the south pole and the far side of the moon.

Fungi can cause disease in humans, animals and plants. Every year, 1.5 million people die from fungal infections, and fungal attacks in food crops threaten food production. To protect ourselves, we have developed chemical agents—in the form of medicines or pesticides—that kill harmful fungi. The most effective remedy against fungal infections is a group of substances collectively known as azoles.

New research reveals that recycled food waste may be contaminated with pharmaceutical residues. The good news is that fungi cultivated in biogas digestate show minimal absorption of these contaminants. On February 16, Astrid Solvåg Nesse will defend her Ph.D. dissertation at the Norwegian University of Life Sciences (NMBU).

Using single photons as qubits has become a prominent strategy in quantum information technology. Accurately determining the number of photons is crucial in various quantum systems, including quantum computation, quantum communication, and quantum metrology.

Managing menstruation in public can be challenging at the best of times, but imagine being eight years old and having to deal with your period at school. You might need to change your pad during class and explain to your friends why you are not going to the swimming carnival. You might be scared you will bleed through your uniform because there aren't any sanitary bins in the junior years' bathroom.

It might look like a comet or a shooting star, but this time-lapse video is actually a tiny plant root, not much thicker than a human hair, magnified hundreds of times as it grows under the microscope.

Scientists working with the powerful telescopes at Georgia State's Center for High Angular Resolution Astronomy (CHARA) Array have completed a survey of a group of stars suspected to have devoured most of the gas from orbiting companion stars. These sensitive measurements have directly detected the feeble glow of the cannibalized stars.

Chile has experienced one of the worst fire-related disasters in its history. A series of huge forest fires burned from February 1 to 5, leaving at least 131 people dead—and this number will probably increase as charred bodies are collected and severely injured people die.

]On 28 October 2003, Barcelona became the backdrop for a tragic incident that would reverberate across the Spanish port city and beyond.

Already valued for its resilience, biomass production and ability to improve soil fertility, bioenergy sorghum has another attribute that researchers have recently characterized: high wax production.

Cornell quantum researchers have detected an elusive phase of matter, called the Bragg glass phase, using large volumes of X-ray data and a new machine learning data analysis tool. The discovery settles a long-standing question of whether this almost–but not quite–ordered state of Bragg glass can exist in real materials.

Like the people they make up, cells communicate by bumping into one another and exchanging handshakes. Unlike people, cells perform these handshakes using the diverse range of sugar molecules coating their surface like trees covering a landscape. Handshakes between these sugar molecules, or glycans, trigger cells to react in specific ways toward each other, such as escape, ignore or destroy.

A multidisciplinary research team at Vanderbilt University and Vanderbilt University Medical Center has discovered a new way to kill a tumor by disrupting its acidic "microenvironment" without harming normal tissue.

When female mosquitoes feed, they don't seem to mind a crowd because lots of carbon dioxide usually means there's food. They were thought to be more solitary, however, when laying eggs. New research has revealed quite the opposite for the deadly Aedes aegypti.

Researchers led by Cornell have discovered an unusual phenomenon in a metal-insulating material, providing valuable insights for the design of materials with new properties by way of faster switching between states of matter.
