Planetary missions on the surface of Mars are carried out with extreme caution. Communication delays between Earth and robotic explorers can range from four to 22 minutes, and limited data transmission capacity adds another layer of constraint. Because of this, scientists must carefully plan each step in advance. Rovers are…
Quantum computers hold enormous promise, but they are still far from dependable. Their biggest weakness is instability, which causes the information they process to quickly break down. Researchers around the world are working to solve this problem, including a team in Norway. “In quantum computers, information is transmitted and stored…
Every second, countless electrical charges move through the human body. These microscopic signals are essential for life. They drive communication between cells, enable energy production, and support metabolism. None of this would work without the careful and controlled movement of charges across cell membranes and within cells. In many ways,…
A well-known 300-million-year-old fossil once believed to be the oldest octopus ever discovered has been reclassified after new analysis revealed it is something entirely different. The specimen had even earned a place in the Guinness Book of Records, but scientists now say that distinction was based on a misinterpretation. The…
Researchers have developed a powerful new way to map how brain cells connect by tagging neurons with molecular “barcodes.” Using this technique, they were able to chart thousands of neural connections in the mouse brain with remarkable speed and detail. This method could deepen understanding of how complex brain networks…
Cornell University scientists have taken a major step toward developing a safe, reversible, long-acting and 100% effective nonhormonal male contraceptive, considered the holy grail of male contraception. In a proof-of-principle study conducted in mice over six years, the team showed that interrupting a key step in meiosis, the process that…
People with higher levels of vitamin D in midlife may have lower levels of tau protein in the brain years later, according to a study published April 1, 2026, in Neurology Open Access, an official journal of the American Academy of Neurology. Tau is a protein closely linked to dementia.…
An Oregon State University scientist working with a group of undergraduate students has revealed new, real-time details about a chemical process tied to Alzheimer’s disease. The discovery could help researchers design more effective drugs in the future. Using a specialized measurement technique, the team tracked how certain metals can trigger…
Scientists at Johns Hopkins Medicine have identified a gene that appears to play a major role in how pancreatic cancer spreads. In laboratory-grown cells, the gene KLF5 (Krueppel-like factor 5) was found to fuel tumor growth and invasion not by changing the DNA sequence itself, but by reshaping how DNA…
An international team of researchers, led in part by scientists at the University of Florida and Trinity College Dublin, has solved a long-standing puzzle in human biology: how our cells absorb a crucial micronutrient linked to brain health and cancer defense. Queuosine — pronounced “cue-o-scene” — is a vitamin-like compound…
Researchers at the University of California San Diego report that a weeklong program combining meditation and other mind-body techniques can quickly produce measurable changes in both brain activity and blood biology. The study found that these practices activated natural pathways involved in brain flexibility, metabolism, immune function, and pain relief.…
Cholera, a dangerous bacterial infection that causes severe diarrhea and can be fatal without treatment, may be significantly reduced through diet. New research from the University of California, Riverside suggests that eating more protein could help limit the infection’s ability to take hold in the body. The study found that…
Modern electronics power everything from smartphones to satellites, but they all share a major limitation. Heat. Once temperatures climb above roughly 200 degrees Celsius, most devices begin to break down. For decades, this thermal barrier has been one of the toughest challenges in engineering. Researchers at the University of Southern…
The Antarctic Circumpolar Current carries more than 100 times the total flow of all the world’s rivers combined. It circles Antarctica without being blocked by land, making it one of the most important drivers of the global climate system. New research published in the journal Proceedings of the National Academy…
A newly identified fossil site in southwest China is changing scientists’ understanding of how complex animal life first developed on Earth. The discovery shows that many major animal groups were already present before the Cambrian Period began. The research was led by teams from Oxford University’s Museum of Natural History…
Life cannot begin on a planet unless certain chemical elements are available in large enough amounts. Two of the most important are phosphorus and nitrogen. Phosphorus helps build DNA and RNA, which store and pass along genetic information, and it also plays a key role in how cells manage energy.…
New observations from the James Webb Space Telescope (JWST) are shedding light on a highly unusual exoplanet known as TOI-5205 b, sometimes described as “forbidden.” Scientists found that this giant planet’s atmosphere contains fewer heavy elements than its host star, a surprising result that could reshape how researchers understand the…
Is consciousness simply created by the brain, or could it be a deeper feature of reality itself? That question is at the center of a presentation by Christof Koch, a leading figure in modern neuroscience, at the 15th “Behind and Beyond the Brain” Symposium organized by the Bial Foundation, taking…
For years, scientists believed the answer centered almost entirely on neurons, the brain’s primary signaling cells. But new research is challenging that idea, pointing to a more complex system involving other types of brain cells. A study published in the Proceedings of the National Academy of Sciences on April 6,…
Researchers have identified four previously unknown tarantula species in the Arabian Peninsula and the Horn of Africa, and they turned out to be far more unusual than expected. “Based on both morphological and molecular data, they are so distinct from their closest relatives that we had to establish an entirely…
There is growing demand for treatments that can safely prevent and reverse bone loss over time. Osteoporosis, a condition that weakens bones and makes them more likely to break, affects about six million people in Germany alone, most of them women. It is especially common with aging and after menopause,…
Researchers led by the University of Warwick have introduced the first unified approach for identifying “spacetime fluctuations” — tiny, random distortions in the structure of spacetime that appear in many efforts to link quantum physics with gravity. These minute variations were first proposed by physicist John Wheeler and are expected…
Imagine setting up an elaborate chain of dominoes, where each piece must strike the next in perfect sequence to create a satisfying final outcome. Quantum circuits operate in a similar way. They consist of many small steps, called (“operations”), that work together to process information in a highly coordinated manner.…
A drug currently being tested to treat hepatitis C may also work against hepatitis E by stopping the virus from reproducing. Hepatitis E infects millions of people worldwide and leads to about 70,000 deaths each year. Despite its impact, there is still no approved vaccine or targeted treatment. That situation…
New research has revealed how to design artificial habitats that give oyster reefs the best chance to recover. The findings come from a detailed analysis of the natural shapes and structures of oyster reefs. Published in the journal Nature, the study shows that oyster reefs are not random clusters of…
Artificial intelligence is consuming enormous amounts of electricity in the United States. According to the International Energy Agency, AI systems and data centers used about 415 terawatt hours of power in 2024. That accounts for more than 10% of the country’s total electricity production, and demand is projected to double…
Despite the enormous variety of languages spoken around the world, certain grammatical patterns keep showing up. A new study finds that about one-third of long-standing “linguistic universals” are backed by strong statistical evidence when tested using modern evolutionary methods. An international research team led by Annemarie Verkerk (Saarland University) and…
A team of researchers in Canada has identified a new way to slow the growth of glioblastoma, the most aggressive and currently incurable type of brain cancer, and they have also pointed to an existing drug that could potentially be used to treat it. The study reveals that some brain…
