The United States is planning new tariffs on some name-brand medicines.
A famous 300-million-year-old fossil that was thought to be the world's oldest octopus—even featuring in the Guinness Book of Records—has turned out to be something else altogether. In what amounts to a case of mistaken identity, the fossil hid its true nature through decay 300

In 2000, researchers thought they found the oldest fossil octopus, which lived over 300 million years ago. But it may just be a half-rotten nautilus.
In an editorial, National Academy of Engineering President Tsu-Jae Liu presents a forward-looking perspective on the role of artificial intelligence in engineering. She describes AI not as a replacement for engineers, but as a tool that can expand their capacity to solve
In December, The Conversation hosted a webinar on AI's revolutionary role in drug discovery and development. Science and technology editor Eric Smalley interviewed Jeffrey Skolnick, eminent scholar in computational systems biology at Georgia Institute of Technology, and
Researchers at Umeå University have contributed new insights into how cancer cells protect themselves from cell death. The study provides a deeper understanding of how key proteins interact within the cell and could, in the long term, support the development of new cancer
In a discovery recently published in Nature, MIT chemists led by Professor Alison Wendlandt have developed a precision technique that allows scientists to seamlessly relocate alcohol functional groups from one spot on a molecule to a neighboring site. The paper is titled
Global efforts to limit climate change require deep cuts to carbon emissions. However, global emissions are still growing. Currently, we emit roughly 42 billion metric tons of carbon dioxide from fossil fuel use and land use changes every year.
Researchers at the National University of Singapore (NUS) have built a molecular "leash" to pull directly on a force-sensing protein called Piezo1, and discovered it switches on at about 15 piconewtons, proving that it can be activated by physical tethers, not only by membrane

Why are frogs diverse in some parts of Africa's rainforests and less so in others? The patterns of cooling and glaciation during the last ice age would probably not have been your first answer or even your last-ditch guess, but it is, nonetheless, correct.
A new study shows that the ups and downs in house prices are far more dramatic than most people think—and that government policies play a big role in making them happen. The researchers analyzed housing markets in 23 OECD countries from 1990 to 2019. They found that during
The cell's endoplasmic reticulum (ER) plays a central role in protein synthesis, folding, and calcium (Ca²⁺) storage. When damaged, ER-phagy (self-eating) removes affected ER regions via double-membrane vesicles called autophagosomes. However, the mechanisms underlying its
For more than a century, the fruit fly has been a workhorse of the biological sciences that has helped scientists to make fundamental breakthroughs in fields such as genetics and neuroscience. As it turns out, human scientists are not the only ones learning during these
When making ethical decisions, university students appear to prioritize fairness and the fate of the worst-off over either reducing total harm or obeying unconditional moral precepts, according to a study published in PNAS Nexus. Woo-Young Ahn and colleagues have designed an
Billions of tons of carbon dioxide are being classified as "dealt with" in global climate plans before anyone can know whether that is true. UT Researcher Rosalie Arendt has given a name to this problem in a new Correspondence published in Nature: Schrödinger's carbon.

Mental load, invisible work, "the extra shift"; no matter the newly coined term, unpaid work in the domestic sphere, predominantly done by women, is a hidden burden eating away at the sleep and mental health of those tasked with it. This work is essential to keep everyone's
Can our forests adapt to a hotter and drier future climate? Temperatures are predicted to rise up to 5°C compared to pre-industrial times. Forest management needs to adapt to these conditions, which requires a better understanding of how heat and drought affect trees. A new
Nearly every object we interact with in our lives has a mass, but where does this mass come from? Modern physics says matter acquires its mass from interaction with a physical vacuum—it is not an empty space, but contains a complex structure. Investigating the system of a
Access to nutritious food is a fundamental pillar of human success, but such access has been unequal throughout history. In pre-industrial European societies, meat was a highly sought-after food, and access to it was often related to a higher social status.
Surface volatiles—chemical substances that easily become gases or fluids at relatively low temperatures and pressures—are transported into Earth through subduction zones, with some being transported into the deep mantle and others to shallower depths. According to conventional
Stem cells are the body's ultimate shape-shifters, sustaining tissues by balancing two competing demands: maintaining their own population and generating specialized descendants. In many tissues, some early descendants can revert to a stem cell state through a process known as
A new tool makes it possible to screen millions of tiny protein fragments and select those that can be recognized by the immune system. The CIC biomaGUNE Center for Cooperative Research in Biomaterials has developed epiGPTope, a system that uses machine learning to generate and

Exposure to "forever chemicals," per- and polyfluoroalkyl substances (PFAS), has been linked to serious health issues, like immune system damage, cancers, pregnancy complications and liver damage. A new study, published in Risk Analysis, finds that the websites people are
In a new Nature Physics publication, University of Amsterdam researchers introduce human-made materials that spring to life. These 'metamaterials' don't just learn to change shape, but can autonomously adapt their shape-changing strategy, perform reflex actions and move around
A new study finds teachers tend to provide assistance to similar subsets of students when using AI-powered educational tools, rather than touching base regularly with everyone in their classes. The findings could be used to develop tools that help teachers track their classroom
Two of the forefathers of quantum theory, Albert Einstein and Niels Bohr, had a famous argument over whether light is a wave or a particle. Columnist Karmela Padavic-Callaghan finds that the matter has been settled once and for all
A fungus that can wipe out up to 50% of a sugar beet crop may soon meet its match in a new generation of smart disease forecasting. A new study published in Phytopathology shows how combining drone imagery, weather data, and qPCR-based airborne spore monitoring can reveal where
The movement patterns of waterfowl, including ducks, swans and geese, may affect the spread of highly pathogenic avian influenza in bird populations, according to a new study from the University of Georgia. The findings are published in the journal Ecology Letters.
The intermediate value theorem shows us how to find an even center on an irregular shape
Ecology is often understood as a hyperlocal thing. The ecology of a pond, for instance, is vastly complex, even if the pond is tiny. But learning solely from local ecosystems is a slow and laborious approach that may not capture widely applicable findings.
In parts of the Midwest and Great Plains, feathery yellow goldenrod and stands of big bluestem sway alongside Indiangrass and other prairie plants, stretching up to eight feet tall. Now, in the search for ways to help ecosystems withstand the weather extremes made worse by
The crew of NASA’s Artemis II mission have captured extraordinary views of the moon, including close-ups of the far side and a breathtaking solar eclipse
As organizations increasingly rely on algorithms to rank candidates for jobs, university spots, and financial services, a new method, named hyperFA*IR, offers a more principled approach when picking candidates based on a limited pool of applicants, especially if minorities are
A new study published in the Biodiversity Data Journal provides a profound look at life up to nearly 10 kilometers below the ocean's surface in the Japan, Ryukyu, and Izu-Ogasawara trenches. The research catalogs at least 108 distinct organism groups (morphotaxa), including the
