A 120-million-year-old fossil forgotten in a museum for nearly a century has revealed a terrifying new dinosaur that may have been more dangerous to humans than a T. rex. The tiger-sized predator also provides the first evidence of megaraptorans in Europe, helping explain how these mysterious dinosaurs eventually became gigantic hunters.
Researchers at McGill University have found that urbanization is weakening one of Earth's most enduring ecological patterns: the tendency for biodiversity to increase toward the tropics, a pattern known as the latitudinal diversity gradient.
Sometimes it can be hard for parents to agree on how to raise children. One parent might insist their child's homework has to be finished before they're allowed to use devices. The other may think a bit of screen time before studying is perfectly reasonable. Rules and consequences might be the preferred strategy of one parent, while the other favors a more flexible approach.
Discarded plastic packaging materials, old CDs and even LEGO bricks can be transformed into materials that capture significant amounts of moisture from the air. Materials chemists Anastasiia Naryshkina, Paul Schweng and Robert Woodward at the University of Vienna have converted several types of plastic waste into water-attracting polymer networks that take up water even in dry climates and release it again under moderate heating, for example, using sunlight. The study, published in Chem Circularity, offers a route to give plastic waste a second life as an adsorbent for atmospheric water harvesting.
Most kinds of coral spawn once a year. In an enormous multiday event synchronized to specific phases of the moon, they release vast slicks of eggs and sperm into the ocean to be mixed together by the drifting currents.
A major study found that several cancers are rising faster among younger adults in England, even as smoking, diet, and other established risk factors have generally improved. Excess weight explains only part of the increase, leaving scientists searching for other possible causes, including changes in the gut microbiome and early-life exposures.
The Wellcome Sanger Institute's Tree of Life program plans to accelerate publication of genome notes from approximately 30 per month to 200, expanding access to research that is supporting advances in agriculture, conservation and medicine. This increase will be facilitated by a new specialized workflow developed by F1000 and the Wellcome Sanger Institute for Wellcome Open Research.
Flat is fine for a sheet of paper, but many of the most useful molecules need depth. Now, researchers from Japan have found a way to give them that depth using nothing more than a single carbon atom.
The gut microbiome is teeming with hundreds of bacterial species and trillions of bacteria. These microorganisms influence many aspects of health, including digestion, and assist with numerous functions in the body. Gut bacteria compete for the limited nutrients available in their environment, while also interacting with each other in ways that can influence the stability of the microbial community.
American audiences will be able to watch an English-dubbed version of "Ramayana," a Hindi film based on a South Asian epic tradition, in theaters in November 2026.
A new study examining how tropical cyclone activity near Hawai'i could change in a warmer future finds a shift toward stronger storms, even though substantial uncertainty remains about whether the total number of storms near the islands will increase.
Many of the Australian animals most at risk of extinction are extremely tough to track down. That's because they live in small pockets of disappearing nature, such as rare grasslands or ancient forests, in worryingly low numbers.
Thousands of Adélie penguins found dead in Antarctica in 2024 were primarily victims of avian cholera, not high pathogenicity avian influenza (H5N1) as researchers initially suspected, according to a study published today in Proceedings of the Royal Society B: Biological Sciences. The findings highlight an underrecognized threat to Antarctic wildlife and the importance of comprehensive disease investigations, particularly as H5N1 continues to raise concerns for seabird and marine mammal populations.
Scientists have long used a powerful gene-editing tool called CRISPR to make precise changes to DNA. But a different version of the technology, known as Cas13a, targets RNA, the genetic material found in viruses such as HIV. Now, researchers at Rice University have developed an improved version of Cas13a that could make it easier to detect HIV and other RNA viruses in blood and environmental samples. The study was published in Cell Chemical Biology.
New research has charted the way U.S. businesses adapted to market shocks caused by reductions in import tariffs and increased foreign competition, with greater innovation emerging as a longer-term benefit.
AI models are good at finding answers to mathematical puzzles but are not as good at research judgment, according to theoretical computer scientists.
A new study co-authored by Tang Yinuo, a tenured associate professor at Peking University HSBC Business School (PHBS), reveals that conservative communities in the U.S. are more likely to resist mergers and acquisitions (M&As) by Chinese companies due to perceived threats and uncertainties.
The western U.S. is facing parallel and escalating hazards in the form of ongoing drought and increasingly frequent wildfires. Although the region's ecosystems have evolved with wildfires, the intensity and frequency of blazes where people live and recreate remain a persistent challenge for communities.
For people with chronic back pain, everyday movements like bending down to tie their shoes or picking up a grocery bag can trigger painful flare-ups. Now, scientists have made a surprising discovery: These episodes may activate a brain network that's associated with our sense of self.In a new study, the researchers found that movement-induced chronic back pain was tied to increased activity in the brain's default mode network, a group of connected brain regions that lights up during self-reflection and mind wandering. This finding was unexpected because the network typically becomes less active during acute pain, such as transient pain triggered from touching a hot stove or banging your knee...
A mollusk's microbial community has more to do with its family tree than its address. In other words, the composition of a mollusk's microbiome depends less on the environment in which it lives and more on what species it belongs to, say University of Michigan researchers.
