Multiple space agencies plan to return astronauts to the moon by the end of this decade. Along with commercial and international partners, these efforts aim to create infrastructure that will ensure a "sustained program of lunar exploration and development." This includes NASA's Artemis Program, China's International Lunar Research Station (ILRS), and the ESA's Moon Village, all of which consist of creating lunar habitats around the South Pole-Aitken Basin. Providing power for these bases is a significant... Читать дальше...

It took about 50 exploding stars to upend cosmology. Researchers mapped and measured light from Type Ia supernovae, the dramatic explosion of a particular kind of white dwarf. In 1998, they announced their surprising results: Instead of slowing down or staying constant, our universe was expanding faster and faster. The discovery of "dark energy," the unknown ingredient driving the accelerated expansion, was awarded a Nobel Prize.

Our understanding of the universe begins with the Big Bang, a moment in time where the universe began expanding into what we see around us now. Big Bang nucleosynthesis describes how only the lightest elements were created originally: hydrogen, helium, and a tiny bit of lithium. For elements heavier than those, which astrophysicists call metals, a generation of stars had to live and die.

Multi-wavelength light sources are required for optical transceivers to increase data. However, scaling the laser array size increases thermal crosstalk, which may affect laser efficiency and reliability.

Play is one of the most important parts of early childhood education in Australia.

A pesky fish may be the culprit behind bleached tropical coral off the coast of the Florida Keys, according to research from the University of Georgia.

With plummeting subscriber numbers, rising costs and users who are sick of endless swiping, the dating app industry is in crisis. Recent layoffs at Bumble are raising questions about the future of dating apps and alternatives for people who want to find romance and connection offline instead.

In the vacuum of space, where temperatures can plunge to -455°F, it might seem like keeping things cold would be easy. But the reality is more complex for preserving ultra-cold fluid propellants—or fuel—that can easily overheat from onboard systems, solar radiation, and spacecraft exhaust. The solution is a method called cryogenic fluid management, a suite of technologies that stores, transfers, and measures super-cold fluids for the surface of the moon, Mars, and future long-duration spaceflight missions.

Betelgeuse is one of the brightest stars in the night sky, and the closest red supergiant to Earth. It has an enormous volume, spanning a radius around 700 times that of the sun. Despite only being ten million years old, which is considered young by astronomy standards, it's late in its life.

Just imagine new AI technology is able to read human emotions flawlessly. How would that affect us as humans? That is the question Ph.D. candidate Alexandra Prégent is exploring.

A few streams on the Cumberland Plateau northeast of Chattanooga are the only places where a small freshwater fish called the laurel dace lives in the wild, so when drought struck the Southeast last summer, the species faced the real possibility of extinction.

Mike returned home to Philadelphia after a 15-year prison sentence and suffered an emotional breakdown.

NASA's Athena Economical Payload Integration Cost mission, or Athena EPIC, is a test launch for an innovative, scalable space vehicle design to support future missions. The small satellite platform is engineered to share resources among the payloads onboard by managing routine functions so the individual payloads don't have to.

After three years of intensive work, four EU projects—AD4GD, B-Cubed, FAIRiCUBE and USAGE—published a joint policy brief offering recommendations to guide the successful implementation of the Green Deal Data Space.

Imagine waking up to the news that a deadly new strain of flu has emerged in your city. Health officials are downplaying it, but social media is flooded with contradictory claims from "medical experts" debating its origin and severity.

Investigators led by Francesca Elizabeth Duncan, Ph.D., the Thomas J. Watkins Memorial Professor of Reproductive Science, have discovered new molecular mechanisms that lead specialized immune cells to cause ovarian aging and functional decline, according to a recent study published in PLOS Biology.

In my writing and rhetoric courses, students have plenty of opinions on whether AI is intelligent: how well it can assess, analyze, evaluate and communicate information.

Bad climate news is everywhere. Africa is being hit particularly hard by climate change and extreme weather, impacting lives and livelihoods.

How proteins in our cells attain their correct three-dimensional structure is crucial to their function—and to our health. Errors in this process can lead to serious diseases. Researchers at the Center for Medical Biotechnology (ZMB) at the University of Duisburg-Essen, together with national partners, have now deciphered a central mechanism of this essential cellular process.

A nuclear winter is a theoretical concept, but if the climate scenario expected to follow a large-scale nuclear war, in which smoke and soot from firestorms block sunlight, came to fruition, global temperatures would sharply drop, extinguishing most agriculture. A nuclear winter could last for more than a decade, potentially leading to widespread famine for those who survive the devastation of the bomb blasts.

For nearly half a century, Brown University marine biologist Jon Witman has been diving Cashes Ledge, an underwater mountain range in the center of the Gulf of Maine that is home to one of the largest kelp forests on the East Coast.

Over the past 100,000 years, Australia and New Guinea's large animal communities have been disrupted by extinctions and invasive species, altering entire ecosystems and threatening the conservation of remaining species.

Southwest Research Institute (SwRI) scientists conducted lab experiments to address a mystery about the origins of frozen hydrogen peroxide (H2O2) on Jupiter's icy moon Europa. Their results, published in the July 2025 issue of Planetary Science Journal, may help explain puzzling observations made by the James Webb Space Telescope (JWST).

Freshwater and coastal waters may cover just a small portion of the planet, but they turn out to be powerful contributors to nitrogen fixation, a natural process essential to life on Earth.

A new study published in Science Advances by researchers from the National Graphene Institute at University of Manchester and the University of Oviedo, has revealed a previously unseen behavior of light in gypsum, a mineral better known for its use in building plaster and chalk.
