Agriculture officials say they've captured more than 1,000 giant African land snails from Pasco County since the invasive pest—"one of the most damaging snails in the world"—was first detected around New Port Richey in late June.
Researchers have discovered natural cellular molecules that drive critical plant immune responses. These compounds have all the hallmarks of being small messengers tailored by plants to turn on key defense-control hubs. Harnessing these insights may allow scientists and plant breeders to design molecules that make plants, including many important crop species, more resistant to disease.
Efforts to conserve the carbon stored in tropical forests would be enhanced by linking the work to the charismatic, threatened primates that live there, researchers say in a new paper.
With energy costs rising, and the rapidly emerging effects of burning fossil fuels on the global climate, the need has never been greater for researchers to find paths to products and fuels that are truly renewable.
How often do stars live alone? For brown dwarfs -- objects that straddle the boundary between the most massive planets and the smallest stars -- astronomers need to uncover more examples of their companions to find out. Ace citizen scientists have done just that by using the Astro Data Lab science platform at NSF's NOIRLab to discover 34 new ultracool dwarf binary systems in the Sun's...
Balancing how much protein you eat with the amount your body needs could reduce nitrogen releases to aquatic systems in the U.S., a new study found.

The U.S. is the world leader in incarceration rates, spending $80 billion a year to imprison 2 million people. But despite these practices aiming to help Americans feel safer, a new Penn State study suggests they may not result in the intended effect.
Physicists working with the world’s biggest dark-matter detector—a behemoth in the United States known as LUX-ZEPLIN (LZ)—released their first results today. They see no sign of what they’re searching for, so-called weakly interacting massive particles or WIMPs. Still, the result is sparking interest among particle physicists, as the nearly 4-decade-long search for...
Climate models may be significantly underestimating how extreme precipitation will become in response to a rise in greenhouse gases in the atmosphere, a new Yale-led study finds.
Most clouds on Earth are made of water, but beyond our planet they come in many chemical varieties. The top of Jupiter's atmosphere, for example, is blanketed in yellow-hued clouds made of ammonia and ammonium hydrosulfide. And on worlds outside our solar system, there are clouds composed of silicates, the family of rock-forming minerals that make up over 90% of Earth's crust. But researchers...
The communities formed by human gut microbes can now be predicted more accurately with a new computer model developed in a collaboration between biologists and engineers, led by the University of Michigan and the University of Wisconsin.
Soil microbiota diversity is closely related to nutrient cycling and sustainable soil management. Complex soil system harbors a vast range of soil organisms of different body sizes and is a regulatory center for the majority of ecosystem functions. However, there is still a lack of a clear understanding of the soil community assembly processes at the whole-community level, i.e., the size gradient...

When words fail, gestures can help to get the message across -- especially for people who have a language disorder. An international research team has now shown that listeners attend the gestures of people with aphasia more often and for much longer than previously thought. This has implications for the use of gestures in speech therapy.
Researchers have identified an increasing trend in medicine-related harm leading to hospital admission.
Copper exposure in the environment and the protein alpha-synuclein in the human brain could play an important role in the pathogenesis of Parkinson's disease. Researchers were able to show how the protein takes on an unusual shape when exposed to large amounts of copper ions. The findings could help develop new strategies for the treatment of neurodegenerative diseases.
Financial incentives play an important role in the widespread adoption of electric vehicles. New research, however, finds that not all financial incentives are created equal in the eyes of prospective car buyers, and the current federal incentive -- a tax credit -- is, in fact, valued the least by car buyers.
Bioengineers have shown that a new strategy can restore damaged stem cells and enable them to grow new tissues again. The new drug delivery system could help infants born from complicated pregnancies.
Lithium extraction from the deep sea, overfishing of deeper-water species, and the unexpected ocean impacts of wildfires on land are among fifteen issues experts warn we ought to be addressing now.
Scientists hsve generated simple kidney-like structures called organoids and used them to identify potential drugs to treat adult-onset polycystic kidney disease. To accelerate the quest for new treatments for ADPKD, researchers used pluripotent stem cells to grow organoids consisting of one or two structures resembling the kidney's filtering units, known as nephrons. To make the organoids useful...
After blue whales, fin whales are the largest whales in the world -- and human beings have hunted both species to near-extinction. After the ban on commercial whaling in 1976, the stocks of these long-lived, but slow-growing creatures are rebounding: researchers have witnessed large groups of up to 150 southern fin whales in their historical feeding areas -- more than has ever been documented...
Researchers identified significant changes to the infant gut microbiome of mice associated with maternal exposure to oxycodone, a commonly used and abused opioid.
Researchers find that, early in its history, the moon was highly porous, which was likely a result of early, massive impacts that shattered much of the crust. They reached their conclusions with simulations and data from NASA's GRAIL mission.
Researchers have established that the destruction of ozone over the Arctic in the spring causes abnormal weather throughout the northern hemisphere, with many places being warmer and drier than average -- or too wet.
Researchers have discovered why reducing particle pollution is leading to a rise in photochemical smog in some emerging economies such as India, Africa and China.
One often thinks that the early embryo is fragile and needs support. However, at the earliest stages of development, it has the power to feed the future placenta and instructs the uterus so that it can nest. Using 'blastoids', in vitro embryo models formed with stem cells, scientists have shown that the earliest molecular signals that induce placental development and prepare the uterus come from...
An international team has discovered a new big, meat-eating dinosaur, dubbed Meraxes gigas, that provides clues about the evolution and anatomy of predatory dinosaurs such as the Carcharodontosaurus and Tyrannosaurus rex. Meraxes measured around 36 feet from snout to tail tip and weighed approximately 9,000 pounds.
