The COVID-19 pandemic introduced uncertainty, fear, and an unparalleled economic shock, resulting in the most extensive government stimulus package—totaling $2.9 trillion—in U.S. history. According to a new study, those stimulus checks more often went to the corporations that
Ehime University investigators measured 34 per- and polyfluoroalkyl substances in 100 commercial dog and cat foods sold in Japan and detected PFAS across many products, with higher concentrations in fish-based foods and dry products, and higher estimated intake from wet products.
Air travel is famously one of the hardest sectors to decarbonize, and the number of air passengers keeps increasing. Electric planes and "sustainable" aviation fuels are still a long way off making a dent in the industry's emissions—if they ever will.
The amount of greenhouse gases produced by the wastewater sector may be higher than reports suggest. According to a paper published in the journal Nature Climate Change, countries are missing out on reporting a significant portion of their emissions.
COVID-19 made remote work and remote learning a new norm for employees and students. But even as many have returned to offices and schools, one of the pandemic's quieter legacies is influencing both the workplace and the classroom: Online degrees are now held in higher regard
Quantum technologies, computers or other devices that operate leveraging quantum mechanical effects, rely on the precise control of light and matter. Over the past decades, quantum physicists and material scientists have been trying to identify systems that can reliably
A new bioengineered neuronal circuit board "BioConNet" allows scientists to artificially engineer human brain-like wiring at scale and can be used to engineer any possible circuit. The fully programmable, open-source system allows generation of large-scale circuits, while
Noise pollution is affecting bird behavior across the globe, disrupting everything from courtship songs to the ability to find food and avoid predators, a large-scale new analysis showed on Wednesday.
A recent study published in Azania: Archaeological Research in Africa explores new historical evidence of one of pre-colonial Dongola's earliest rulers. Previously considered semi-legendary, the discovery of a document in which orders were issued in the name of King Qashqash
Hundreds of millions of animals are killed on our roads each year. Now, scientists have revealed how these deaths could play an unexpected role advancing wildlife science and conservation.
Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in a coordinated way throughout the body. About a quarter of cell types change in
While the number of Californians ages 12 and older who said they experienced a hate act increased in 2024, a new UCLA Center for Health Policy Research (CHPR) study showed how someone's likelihood to experience a hate act was associated with race, ethnicity, gender identity,
A team of scientists from the University of Manchester and Oxford have synthesized stable nitrogen chain radical anions under ambient conditions. These molecules, which are normally too reactive to isolate and study under ambient conditions, are described in a new study,
A popular climate theory suggested that melting Antarctic glaciers would release iron into the ocean, sparking algae blooms that pull carbon dioxide from the air. New field data from West Antarctica reveal that meltwater provides far less iron than scientists once believed.
Sponges may be ancient, but their timeline has been murky. New research suggests the earliest sponges were soft and skeleton-free, explaining why their fossils don’t appear until much later. By analyzing hundreds of genes and modeling how skeletons evolved, scientists found
Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying zebrafish embryos, researchers found that instead of forming a fully closed
Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial protein called MurJ, which is essential for building the bacterial cell wall.
Scientists at Texas A&M are turning an everyday pick-me-up into a high-tech medical switch. By combining caffeine with CRISPR gene editing, researchers have created a system that allows cells to be programmed in advance — and then activated simply by consuming a small dose of
Scientists have found a way to use common bacteria as tiny, green chemical factories to replace a process that currently relies on fossil fuels. In industrial hydrogenation, the hydrogen added to molecules to create products such as plastics, medicines and food typically comes
Thousands of companies around the world now regularly disclose aspects of their water use as part of corporate commitments to environmental, social, and governance goals. Yet reliable measures of corporate water withdrawals and discharges—and their impacts on local water
Scientists share their work by publishing articles in journals, such as Nature, Science or PLOS Biology. One major part of the publishing process involves having these manuscripts reviewed by unpaid peers. These scientists specialize in the same topic and volunteer to make sure
This week, astronomers reported that one of the biggest observed stars in the universe could soon explode. A study compared long-term COVID-19 brain effects to the flu. And a new eco-friendly battery could theoretically last for centuries (or for several hours if you put it
Scientists racing to tackle plastic pollution have created a surprising new contender: a biodegradable packaging film made partly from milk protein. Researchers at Flinders University blended calcium caseinate with starch and natural nanoclay to form a thin, durable material
Older people with exceptional memory have a surprisingly high number of young neurons, a study finds
The U.S. National Flood Insurance Program is going broke. Increased flood strikes in more places, combined with outdated ways of predicting flood risk, are putting property owners at risk and the program itself in over $20 billion of debt.
To further the quantitative understanding of cellular decision making, Dr. Gregory Reeves and his team in the chemical engineering department have worked to interpret how a transcription factor dictates the alteration of gene expression in cells.
This mysterious interstellar visitor is on a whirlwind journey through our solar system
Scientists at UC Berkeley have discovered a microbe that bends one of biology’s most sacred rules. Instead of treating a specific three-letter DNA code as a clear “stop” signal, this methane-producing archaeon sometimes reads it as a green light—adding an unusual amino acid and
Like so many sectors of the economy, the news industry is hurtling toward a future where artificial intelligence plays a major role — grappling with questions about how much the technology is used, what consumers should be told about it, whether anything can be done for the
