The lead in some bullets used for hunting deer, moose, and elk is toxic to the humans who eat the harvested meat and to scavenger animals that feast on remains left in the field.

The remarkable effectiveness of mRNA vaccines against SARS-CoV-2 has generated much interest in synthetic mRNA therapeutics for treating and preventing disease. But some basic science questions have remained about whether the modified nucleotides used in the vaccines faithfully produce the protein products that they are designed to make.

NASA's Artemis missions are returning humanity to the Moon and beginning a new era of lunar exploration. Soon, the agency plans to launch the Artemis I mission, an uncrewed flight test that will take a human-rated spacecraft farther than any before.

A sounding rocket launch testing science instruments for future missions was successfully conducted at 9:16 p.m. EDT, Aug. 23, 2022, from NASA's Wallops Flight Facility in Virginia.

President Joe Biden on Wednesday announced detailed plans to deliver on a campaign promise to provide $10,000 in student debt cancellation for millions of Americans—and up to $10,000 more for those with the greatest financial need—along with measures to lower the burden of repayment for their remaining federal student debt.

Quantum computers offer the potential to solve computational problems that are beyond the reach of classical computers. As an example, the Canadian company Xanadu recently claimed that its quantum computer has been able to solve, in just 36 microseconds, a computational task that would have required 9,000 years using state-of-the-art supercomputers.

Researchers have discovered a huge new mosasaur from Morocco, named Thalassotitan atrox, which filled the apex predator niche. With massive jaws and teeth like those of killer whales, Thalassotitan hunted other marine reptiles—plesiosaurs, sea turtles, and other mosasaurs.

The University of California, San Diego says the atmospheric river storms that periodically hit the western U.S. could cause as much as $3.2 billion a year in flood damage by the end of the century, a figure three times higher than an estimate the university made in 2019.

The human immune system is a complex network of organs, cells and proteins that defend the body against infections and diseases. While our bodies work constantly to ensure invading infections don't breach the defenses, viruses are working just as hard to coerce our immune systems into allowing access and staying quiescent.

Scientists from Rochester Institute of Technology are turning studio photography technology on its head to help museums and other cultural heritage institutions preserve historically significant artifacts. Faculty and students from RIT's Munsell Color Science Laboratory have developed new LED-based spectral imaging techniques they say will offer small to medium museums a practical way to capture accurate digital representations of items in their collections.

Sea lions are being poisoned by a toxin found in plankton and reports of the sick animals being spotted along the Ventura County coast are skyrocketing, according to an animal rescue organization.

A time-lapse video shows a baby blue straw sitting in a tank of water and rocks.

Years late and billions over budget, NASA's new moon rocket makes its debut next week in a high-stakes test flight before astronauts get on top.

Using a suspended nanowire, a University of Massachusetts research team has, for the first time, created a tiny sensor that can simultaneously measure electrical and mechanical cellular responses in cardiac tissue, work promising for cardiac disease studies, drug testing and regenerative medicine.

Lower-to-middle-income countries still struggle with high unemployment rates after COVID-19 lockdowns and economic restrictions, unlike higher-income countries such as Canada, finds a new study led by York University with the University of Witwatersrand in Johannesburg.

College students who are marginally placed into "high-ability" classes have lower grades and graduation rates, according to new Cornell research.

Oxytocin has sometimes been called "the love hormone." The past decade of research, though, has challenged this idea, meaning that this evolutionarily ancient neuropeptide hormone is involved not only in in-group love but may also be involved in out-group hate.

Before Hurricane Katrina hit New Orleans in 2005, evacuation planners rarely considered the needs of carless and vulnerable populations—low-income, elderly, or young individuals with specific needs or tourists without a car while on vacation. In the aftermath of the storm, transportation planners called for a new focus on evacuation planning to meet these specific needs.

Intermolecular interactions are the forces that pertain between molecules. In general, these interactions scarcely extend beyond the boundaries of molecules. For the most part, they are effective over distances of less than 1 nanometer (10-9 m).

A new, international study suggests that dog owners who spend more time exercising themselves tend to exercise their dogs more, and more active owners are also more likely to perceive their dog's body weight as being ideal. Sydney Banton of the University of Guelph in Ontario, Canada, and colleagues present these findings in the open-access journal PLOS ONE on August 24, 2022.

A new study identified multiple risk factors, including high utility bills, employment hardship, and medical hardship, that may lead to food insecurity among mothers of young children, according to researchers at UTHealth Houston.

Short animations giving viewers a taste of the tactics behind misinformation can help to inoculate people against harmful content on social media when deployed in YouTube's advert slot, according to a major online experiment led by the University of Cambridge.

A new discovery from the University of Virginia School of Medicine has shed light on how our digestive tract, lungs and liver form, and that finding could have important implications for our understanding of cancer.

Chemotherapy sucks. The treatments generally have awful side effects, and it's no secret that the drugs involved are often toxic to the patient as well as their cancer. The idea is that, since cancers grow so quickly, chemotherapy will kill off the disease before its side effects kill the patient. That's why scientists and doctors are constantly searching for more effective therapies.

The remains of what could be the largest dinosaur to be found in Europe are being uncovered in a backyard in Pombal, a city in the central region of Portugal. The remains, that could correspond to a sauropod dinosaur with approximately 12 meters high and 25 meters long, are now being studied by an international research team.
