New observations by a team of US astronomers have cast fresh doubt on whether the lunar surface could host abundant water ice. Publishing their results in Science Advances, a team led by Shuai Li at the University of Hawaii at Manoa has shown that relatively pure ice (making up
"Project Hail Mary," the Ryan Gosling-led adaptation of the best-selling sci-fi novel from Andy Weir, is being praised for putting the science in science fiction. Although aliens, sun-draining microorganisms and galaxy-spanning spaceflight are all a part of the story of a
A court ruling that blocks Trump administration vaccine policy is a win for science. But much work remains to rebuild trust in vaccines.
Tiny pieces of plastic, called microplastics, are showing up everywhere, even in the water in clouds, rain, and snow—and they may be affecting our weather and temperatures. A study published in Environmental Science & Technology and led by Hosein Foroutan, associate professor

Every time we do a load of laundry, tiny fibers of polyester escape from our clothes and slip down the drain. These microfibers, so small they can be invisible to the naked eye, are among the most common forms of microplastic in the ocean. Yet, new research published in Journal
Like the males of many animal species, male Drosophila melanogaster fruit flies, a commonly studied lab animal, are aggressive toward one another and even fight when competing for resources such as food and females. Researchers in the lab of David Anderson have been studying
For millennia, sling bullets served as a hand-thrown projectile that could be used to fend off enemies. At Hippos, 70 sling bullets made of lead have been recovered over the course of fieldwork and excavation. However, while many are bare or depict scorpions and thunderbolts,
Ryan Gosling is on a mission to save the sun — and Earth — from star-killing microbes. Science News dissects the science behind the sci-fi movie.

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after replication. Instead, they use a process called binary fission, which is faster
Despite polyethylene terephthalate (PET) being one of the most widely recycled plastics, only about 20% of used PET bottles are actually recovered as high-quality raw materials. The majority are transformed into lower-grade fibers or fillers before eventually being discarded.
For her Ph.D. at VUB and KULeuven, Aarushi Caro created a kind of systematics for dendritic cells, a special group of immune cells in the fight against cancer. Until now, there was a lot of confusion about the different types of dendritic cells. "Scientists worldwide use
In a new study, scientists from the universities of Portsmouth and Manchester report that a specially engineered enzyme can significantly speed up the breakdown of PET—the plastic used in water bottles, food packaging and polyester clothing—when it is processed at high
More and more people are turning to AI chatbots as if they were close friends—venting about personal struggles, asking for advice, and even sharing their deepest secrets. These conversations can feel strikingly real, with some users saying they're indistinguishable from
University of Phoenix announces the publication of "Harnessing AI, Virtual Landscapes, and Anthropomorphic Imaginaries to Enhance Environmental Science Education at Jökulsárlón Proglacial Lagoon, Iceland" in Glacies.

Computer simulations can help people gain a better understanding of the situation faced by migrants. This is shown by a new study in which 148 teenagers were assigned random migration pathways, with different start and end points. Along the way, they encountered unforeseen
Autism researchers are working to counter a federal autism advisory panel that has vaccine skeptic members and, they say, a “striking absence of scientific expertise”
For the second time this year, NASA moved its moon rocket from the hangar out toward the pad Friday in hopes of launching four astronauts on a lunar fly-around next month.
In new research published in Physical Review X, scientists have designed quantum control protocols that generate processes more consistent with time flowing backward than forward. The protocols—techniques to control quantum systems—modify a quantum system's "arrow of time," the
A record early heat wave striking the west of the United States on Friday is a one-in-500-years type event and all but certainly the result of human-caused climate change, experts say.
This spring, these six orchids will lure pollinators with mimicry, scent or other unusual strategies.
Plant immunity is largely initiated at the cellular level, with each cell capable of autonomous detection and response, while also coordinating systemic signaling across the organism—unlike the centralized, cell-based immune system of animals. One of the key mechanisms of plant
Scientists at Royal Botanic Gardens Victoria, Australia have described two new species of fungi, Peziza austroechinospora and Peziza meridionalis with the assistance of DNA sequencing, highlighting how modern science is revealing vast, hidden biodiversity beneath our feet.
Researchers at the University of Seville have demonstrated the effectiveness of active vertical garden systems in improving indoor air quality in buildings. To do so, they worked inside a closed glass chamber installed at the Higher Technical School of Agricultural Engineering,

Fake news can be tricky to spot, but spotting fake drugs just got a little easier. Researchers have devised a low-cost way to help distinguish legitimate medications from counterfeit ones.
Chemists may soon have one less rigorous step to worry about when searching for the right molecules to accomplish their highly specific innovation needs. Scientists have now built a new machine learning model that can predict the electric dipole moments of diatomic molecules
The ALICE Collaboration takes a step further in addressing the question of whether a quark–gluon plasma can be formed in proton–proton and proton–nucleus collisions. In the first few microseconds after the Big Bang, the universe was in an extremely hot and dense state of matter
Researchers have known for decades that female mosquitoes—the ones responsible for the itchy and irritating bites that can also transmit disease—lose their desire to bite humans for several days after feeding, as they digest blood and convert it to yolk protein that they
Animals come in an extraordinary range of body shapes. A starfish looks nothing like an earthworm, a mouse, or a human. Yet even closely related species can appear radically different: corals, jellyfish, and sea anemones all belong to the same biological phylum, but their
For ants, the ability to instantly distinguish nestmates from outsiders who might hijack the colony is crucial. Now, a new study shows that the system that ants use to determine who belongs in the colony is far more flexible than once thought. The findings, published in Current
Mosquitoes stop feeding because signals from rectal cells tell them they’re full, offering a target for preventing human bites.
