Mayo Clinic researchers developed an experimental nanotherapy that delivers two cancer drugs directly to brain tumors, according to a study published in Communications Medicine. The strategy extended survival in preclinical models of glioblastoma, the most aggressive form of brain cancer. [...]
A research team at the University of Tokyo has developed a new microscopy platform that can observe a previously hidden layer of biomolecular chemistry linked to weak magnetic fields. The work, led by Project Researcher Noboru Ikeya and Professor Jonathan R. Woodward at the Graduate School of Arts and Sciences, addresses a long-standing technical gap in life-science measurement: Many important intermediates in spin-dependent reactions are "dark" molecules that do not emit light directly and therefore escape conventional fluorescence imaging. [...]
The doctoral thesis of Sophia Hollick, Ph.D. '25, a recent graduate of Yale's Wright Lab in professor Reina Maruyama's group, has significantly contributed to answering a decades-long question in her field about whether or not a signal observed in an experiment that has taken data since 1997 was indicative of a direct detection of dark matter. The results of her analysis, which have excluded the dark matter explanation with greater confidence, were published in Physics Review Letters in the article "Combined Annual Modulation Dark Matter Search with COSINE-100 and ANAIS-112." [...]
Cell cultures—single layers of cells grown in a small dish—have enabled researchers to study biological growth, develop or test drugs and even discover what causes some diseases. Cell spheroids, 3D versions of cell cultures built using a process known as cell aggregation, are the next step in advancing this work, capable of more closely modeling real tissue. A new technology, invented by researchers from Penn State and detailed in a paper published in Advanced Science, could breathe fresh air into bottom-up tissue fabrication and potentially large-scale tissue engineering by addressing these issues. [...]
U.S. officials are taking a closer look at what's in America's drinking water, including microplastics and leftover medications. [...]
In Puerto Rico, drought doesn't always arrive slowly. Sometimes, it appears in days. That speed can leave producers scrambling, reservoirs dropping, and communities facing water restrictions before they can react. In a place often associated with heavy rain and hurricanes, drought is often overlooked, but very much a reality. New research from Virginia Tech is helping explain why. [...]
Just as embroiderers, with needle and thread, can transform plain fabric into an intricate pattern, engineers can use lasers and polymers to create flexible, complex structures that could transform life-saving sensing technology. An interdisciplinary team at the University of Pittsburgh's Swanson School of Engineering has developed a new manufacturing strategy that reveals where and how laser-induced graphene (LIG) forms on polymers. [...]
Reef sharks are observed less frequently on Caribbean reefs that have high levels of diving activity and greater coastal development, according to new research published in the Journal of Applied Ecology. Even recreational activities that are often considered low impact are associated with fewer sharks on these reefs. Reef sharks play an important role in maintaining healthy reefs by helping to keep the ecosystem in balance. [...]
How can we predict species' responses to always-arising changes in our world? A long-term ecological study from Yokohama National University researchers suggests the answer may lie in a few small simple biological traits. Their findings offer a framework for better anticipating biodiversity change and improving proactive conservation strategies. The results were published in Nature Communications on March 14. [...]
New evidence suggests that a disease-causing tapeworm that has been spreading across the United States and Canada has arrived in the Pacific Northwest. The tapeworm, called Echinococcus multilocularis, lives as a parasite in coyotes, foxes and other canid species and can cause severe disease if passed to domestic dogs or humans. [...]
Most people think of diamonds as high-end adornments. Not Ania Bleszynski Jayich. The UC Santa Barbara physicist sees diamonds, which she grows in the UC Quantum Foundry, as a potentially powerful foundation for quantum sensors. Sensors are currently much farther along in their development than other potential quantum applications. Diamond sensors are particularly promising because diamonds require relatively few quantum bits (qubits) to operate, whereas a quantum computer, for instance, requires more than 100,000, perhaps as many as a million, qubits to handle error correction, one of the main hurdles for quantum computing. [...]
University of Tennessee Knoxville professor and Goodrich Chair of Excellence in Civil Engineering Frank Loeffler and his co-authors published new research on the environmental impacts of "forever chemicals" in Nature Microbiology. Their study uncovered that bacteria incorporate polyfluoroalkyl carboxylates—a type of per- and polyfluoroalkyl substances (PFAS)—into the molecules that make up their cell membranes. [...]
With its striking San Francisco Bay settings, director Alfred Hitchcock's iconic horror film "The Birds" has captivated audiences for more than 60 years. For Hitchcock, the film—set in an ocean-side town terrorized by swarming, murderous birds, was about how an unexpected threat could shatter everyday life. Today, the plot reads like a warning about our warming climate. [...]
Debates over how geometry is understood and learned date back at least to the days of Plato, with more recent scholars concluding that only humans possess the foundations of this understanding. However, a new analysis by New York University psychology professor Moira Dillon concludes that geometry's foundations are shared by humans and a variety of other animals—from rats to chickens to fish. [...]
Imagine a creature nearly twice the size of a modern African elephant, which can weigh up to 6,000 kg. This was Elephas (Paleoxodon) recki, a prehistoric titan that roamed the landscape of what is now Tanzania nearly two million years ago. Now, imagine a group of our ancestors standing over its carcass, then butchering it and eating it. [...]
Warming temperatures from climate change cause tree swallows to nest up to two weeks earlier than they did in the 1970s, but early spring cold snaps can hinder nestlings' growth and survival, according to a new study that incorporates a four-decade Cornell dataset on the birds. [...]
An understanding of community resilience and risk analysis is vital when it comes to protecting civilians and infrastructure from natural hazards, such as hurricanes or earthquakes. Artificial intelligence is an efficient way to rate a community's resilience and vulnerability. However, factors that affect community resilience—like power grids and communications systems—are ranked independently by current assessment methods based on the assumed impact of each factor. [...]
It transports far more than 100 times as much water as all of the Earth's rivers combined: The Antarctic Circumpolar Current rushes around the southern continent unhindered by land masses and is therefore a fundamental component of the climate system. In a recent study published in the journal Proceedings of the National Academy of Sciences, a research team led by the Alfred Wegener Institute describes how and when this mighty ring current developed in Earth's history. [...]
A longstanding mystery in mosquito biology has been solved, opening a potential new path for controlling mosquitoes and the diseases they spread. For decades, scientists believed that juvenile hormone, a chemical signal essential for mosquito reproduction, needed two different receptors to work: one inside the cell and another on its surface. The internal receptor was identified years ago, but the second remained elusive. [...]
Why do cats often leave food unfinished? Many cat owners have experienced this puzzling behavior. Domestic cats are well known for eating multiple small meals throughout the day, a pattern thought to reflect their evolutionary origin from the African wildcat (Felis silvestris lybica), a solitary hunter that repeatedly captures small prey. It has also often been assumed that cats leave food unfinished simply because they have a small appetite or a capricious nature. However, the mechanism underlying this characteristic feeding pattern has remained unclear. [...]
Researchers at Cornell University have developed a powerful new genetic toolkit that allows scientists to study how genes function at the level of individual cells, an advance that could accelerate discoveries in development, neuroscience, and disease. The work is published in the journal eLife. [...]
The four astronauts embarking on NASA's lunar flyby became on Monday the humans to travel farthest from our planet, as they begin documenting areas of the moon never before seen by the naked eye. [...]
Snow leopards, leopards, and Himalayan wolves all share similar stomping grounds in Nepal's Lapchi Valley in the Himalayas. A recent study, published in PLOS One, has taken a closer look at how these apex predators have found a way to coexist, despite limited resources. [...]
Scientists have found a new way to detect subtle chemical signatures in seawater, revealing previously invisible details about the ocean's chemistry from data continuously collected by thousands of autonomous robotic floats drifting across the seas. [...]
A new study led by scientists from the Wildlife Conservation Society (WCS) and Woods Hole Oceanographic Institution (WHOI) reveals that endangered sei whales regularly use the New York Bight as a key spring habitat, underscoring the importance of this heavily trafficked region for one of the world's fastest and most elusive baleen whales. [...]
Fences are among conservation's most controversial interventions. To some, they are essential for conserving wildlife, minimizing encroachment, and preventing the type of conflict that happens when humans come into contact with wildlife. [...]
If you were rewarded for following a particular pattern of behavior, wouldn't you keep doing it? The answer turns out to be more nuanced than you might think. In a new study, University of Iowa researchers report that pigeons rewarded with food after pecking five buttons in any order did, indeed, decrease the variety of their sequences. However, the birds kept their options open, never gravitating toward a single sequence and consistently electing to try different sequences. [...]
As governments worldwide explore how artificial intelligence can transform decision-making, a recent study from Sultan Qaboos University demonstrates how AI can uncover hidden connections within legal systems—offering a powerful tool to support smarter lawmaking. Published in The Journal of Engineering Research, the study applies natural language processing (NLP) and network analysis to Oman's Labor Law of 2023, revealing a complex web of interdependencies between its articles that may not be apparent through conventional legal review. [...]
Just because a female olive baboon has mated with a specific male doesn't mean he will be the father of her offspring. According to a new study published in PLOS Biology, mate selection continues long after copulation as the vaginal tract appears to "weed out" genetically incompatible suitors. [...]
Cultivating flowering plants for pollinator gardens, commercial farms, or home landscapes often relies on the use of herbicides to manage unwanted weeds. Honeybees are attracted to these locations and play a critical role in their success. So what happens when foraging bees pick up a dose of weedkiller? [...]
