A study incorporating new DNA data and archaeological evidence has shown that the last Neanderthals in Europe experienced a major population turnover, resulting in little diversity in their gene pool prior to their disappearance some 40,000 years ago.
Astronomers have observed two planets forming in the disk around a young star named WISPIT 2. Having previously detected one planet, the team has now employed European Southern Observatory (ESO) telescopes to confirm the presence of another. These observations, and the unique
A team of scientists re-created the way Neandertals made birch tar and found its antibacterial properties could fight off skin infections.
Almost all living things have an internal 24-hour clock that remains accurate regardless of temperature or other environmental changes. This clock is a highly sophisticated yet simple timekeeping mechanism that is critically important to many functions, including metabolism and
Superconductors are materials that conduct electricity with an electrical resistance of zero. Superconductivity is generally observed when materials are cooled down to extremely low temperatures. In some cases, however, like in so-called high-temperature superconductors, this
Penn Engineers have redesigned a key component of lipid nanoparticles (LNPs), the delivery vehicles behind mRNA vaccines, to steer the particles toward lymph nodes while reducing off-target delivery to the liver. The advance could make mRNA vaccines more efficient, potentially
Some of the longest, most important migrations of species on Earth are happening beneath the surface of the world's rivers and many are rapidly collapsing, according to a major new assessment by the Convention on the Conservation of Migratory Species of Wild Animals (CMS), an
This subset of exoplanets are the most likely to be habitable The post The Search for Alien Life Just Identified 45 New Targets appeared first on Nautilus .
Astronomers have finally cracked a decades-old mystery about red giant stars—how material from their deep interiors makes its way to the surface. Using cutting-edge supercomputer simulations, researchers discovered that stellar rotation plays a powerful role in mixing elements
Scientists have uncovered a new species of rhinoceros in the Canadian High Arctic, revealing that rhinos once lived far farther north than expected. The fossil, dating back 23 million years, is unusually complete and has helped reshape ideas about how these animals migrated
As the science fiction author publishes the latest novel in his Children of Time series, Children of Strife, he talks to Alison Flood about mantis shrimp, the pleasures of sci-fi and why empathy is so important in his writing
A global team of leading scientists is zeroing in on a tiny but powerful molecule that could reshape how we age. Known as NAD⁺, it plays a crucial role in keeping our cells energized, repairing DNA, and maintaining overall health—but its levels steadily decline over time,
When we learn something new, that information does not exist in isolation. It integrates into the complex landscape of our knowledge, forging connections with existing ideas and opening up possibilities for new learning. In a study in Nature Communications, Dartmouth
Every plant cell is the product of a biological merger billions of years ago. Chloroplasts are key structures in plants and algae that capture sunlight, but originally they were free-living bacteria that took up residence inside another cell. Over time, these partners became
The research into whether social media is addictive is nuanced and complex, with many unanswered questions
Are we evolving to be more stupid? Humans have a relatively high genetic mutation rate, which has been thought to be driving down our physical and mental fitness – but columnist Michael Le Page finds these mutations aren’t the health risk some make them out to be
Scientists in Geneva are taking some antiprotons out for a spin—a very delicate one—in a truck, in a never-tried-before test drive.
For over a century, scientists have chased the dream of insulin pills, but the digestive system kept destroying the drug before it could work—forcing millions of patients to rely on daily injections. Now, researchers at Kumamoto University have developed a clever workaround
Visible to the naked eye in the constellation Cassiopeia, the star γ Cas has puzzled astrophysicists for half a century. It emits X-rays of an intensity and temperature incompatible with what one would expect from an ordinary massive star. Observations, carried out using the
Researchers from Xi'an Jiaotong-Liverpool University (XJTLU) in China have developed a streamlined process that makes it easier to produce tiny therapeutic particles released by cells, called exosomes, which are being explored as a new type of medical treatment. Using a
Scientists have turned simple glass into a powerful quantum communication device that could safeguard data against future quantum attacks. The chip combines stability, speed, and versatility—handling both ultra-secure encryption and record-breaking random number generation in
Scientists have found a clever way to supercharge ultra-thin semiconductors by reshaping the space beneath them rather than altering the material itself. By placing a single-atom-thick layer of tungsten disulfide over tiny air cavities carved into a crystal, they created
Each year, antimicrobial resistance (AMR) is responsible for an estimated 1.1 to 1.4 million deaths worldwide. Now, scientists have found evidence that the spread of AMR isn't always driven by bacteria evolving to resist the antibiotics themselves: rather, certain weedkillers
Foams have long baffled scientists because liquid drains from them far sooner than theory predicts. New research shows the reason: the bubbles don’t stay put—they rearrange, opening pathways for liquid to escape. The key factor is the pressure needed to shift bubbles, not just
Two new species of black bass have been officially identified after decades of confusion with similar fish. Bartram’s bass and Altamaha bass stand out not just in appearance, but in their DNA, revealed through detailed genetic analysis of hundreds of specimens. Scientists say
Drone footage has revealed sperm whales headbutting each other—something scientists had only speculated about until now. Surprisingly, it’s younger whales doing it, not the giant males researchers expected. The behavior echoes old seafaring tales of whales smashing ships, once
For the first time, scientists have reconstructed the full history of a galaxy outside the Milky Way using chemical clues. By analyzing oxygen across NGC 1365 and comparing it with simulations, they traced its growth over 12 billion years. The findings show how its core formed
A new data visualization illustrates how an experimental NASA technology can provide extra lead time to communities in the path of a tsunami. Called GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network), the software detects slight distortions in
A new study suggests a widely used bone hormone could help relieve chronic back pain in an unexpected way. Instead of just strengthening bone, it appears to stop pain-sensing nerves from growing into damaged spinal areas. In animal models, this led to stronger spinal tissue and
Worries about the British economy have long been dominated by one persistent concern—weak productivity. Since the financial crisis of 2008, growth has stagnated, leaving the UK trailing well behind the US, France and Germany across that whole period.
Unless your employer is Lumon Industries, where the "Severance" workday never ends, a canceled meeting can feel like a gift of limitless time. A Rutgers University study published in the Journal of the Association for Consumer Research explains why: Unexpectedly gaining time
Postmenopausal women may have a powerful new edge in the battle against weight gain. A Mayo Clinic study found that those using menopausal hormone therapy while taking the obesity drug tirzepatide lost about 35% more weight than those on the drug alone. The findings hint at a
Hollywood loves a comeback story: a director who flopped and then returned with a masterpiece or the producer who went bust and bounced back with a winner. It's a narrative rooted in the business belief that failure is a great teacher. But what if, for certain teams, failure
Researchers have developed a teeth-whitening powder that works with the vibrations of an electric toothbrush to safely remove stains. Unlike traditional whiteners, it not only brightens teeth but also repairs enamel and supports healthy oral bacteria. Lab tests showed dramatic
During a widespread crisis, negative emotions don't simply go away once the workday begins. Organizational scholars who study how emotions affect employees tend to assume that negative emotions equal negative outcomes. That isn't always the case, according to new research from
New research finds the addition of a thousand new immigrants in a metropolitan area reduces elderly mortality by about 10 deaths than would be typical. Why? Because among the newcomers are foreign-born health care workers who are arriving amid a critical nationwide shortage,
A new Caltech study indicates that drought increases the abundances of antibiotic-resistant microorganisms in soils, which directly correlates with an increase in antibiotic-resistant infections in hospitals. In other words, regions experiencing high aridity—hotter, drier
A research team led by the Museum für Naturkunde presents the first evidence that several bat species produce courtship songs in the immediate rotor-swept zone of wind turbines while circling around the nacelle. Data from over 80,000 audio recordings at nacelle height from six
A new biosensor developed at the Department of Energy's Oak Ridge National Laboratory detects the emerging presence of fungus on plants at the molecular level, paving the way for next-generation crop protection and the development of stress-tolerant plants. The innovation
For the last few decades, researchers have been studying what the universe looked like in its first seconds. It is generally accepted that the universe expanded exponentially in the first fraction of a second after the Big Bang. Researchers use ns, the scalar spectral index, to
A stark rise in the number of stray dogs being euthanized across the UK and the Republic of Ireland, with rates more than tripling over a three-year period, are revealed in a new collaborative study. The research is published in Animals.
A paper published in the journal Quaternary International reveals a distinctive technological behavior at level TD10.2-BB of Gran Dolina (Atapuerca, Burgos), characterized by the almost exclusive use of local chert and linked to one of the earliest pieces of evidence of
In the earliest phase of creating human proteins, the protein complex NAC performs an essential task by starting the first steps toward folding proteins into their correct three-dimensional structures. An international research team led by scientists from the Center for
Researchers from the Earlham Institute, in collaboration with the Department of Biology at the University of Oxford, have discovered three previously unrecognized lineages of the protist Bodo, each with its own bacterial endosymbiont (a symbiotic organism living within the body
Plants need water, light, and air to thrive. But when they transport water from the soil up to their leaves, they defy gravity. Scientists describe this astonishing phenomenon as "negative water potential," a form of negative tension that enables herbs, shrubs, and trees to
In nature, a certain size is often a prerequisite for biomolecules to perform their specific functions. For example, for proteins or DNA to fulfill their vital tasks, they must be folded in a precise manner—and this requires a certain minimum length.
Some materials behave unexpectedly. They crack differently than expected, or react in ways that are hard to explain. The answer often lies in their atomic structure. Is it neatly arranged, as in a crystal, or disordered, as in glass? Researchers at the University of Twente have
In conventional pathology and physiology research, two-dimensional (2D) analysis—observing thinly sliced tissue sections—has been mainstream, making it difficult to comprehensively understand the distribution of cells across entire organs or throughout the whole organism.
In 1066, England was invaded by multiple foreign powers. A northern force led by King Harald Hardrada of Norway advanced on York via the River Humber, while a southern force, led by Duke William of Normandy (later William I the Conqueror) crossed the Channel with forces from
Findings from a new University of Cincinnati study have reshaped the fundamental understanding of how a certain cell organelle prepares its environment for cellular digestion. The study, led by UC's Jiajie Diao, Ph.D. and published in Cell Reports, focused on the lysosome, an
