Scientists analyzing the genomes of thousands of people across Japan discovered evidence for a previously overlooked third ancestral group, challenging the long-accepted “dual origins” theory. The newly identified ancestry appears linked to the ancient Emishi people of
Symbiosis, or the interaction of two unalike species, is common and often necessary for survival. In insects, symbiotic microbes often facilitate and promote the growth of hosts. Before the symbiotic collaboration can begin, however, hosts must acquire their symbionts.
Heat conditions could exceed dangerous levels at a quarter of the planned 2026 World Cup soccer matches, including the final in New Jersey on July 19
Just a few hours before the Orion spacecraft crossed the sky en route to the moon on April 1, mechatronics engineer Rodrigo Trevisan Okamoto received confirmation he had been waiting for since the Artemis 2 mission was announced in 2023. The email from NASA stated that the crew
Earth is quietly collecting radioactive debris from an ancient stellar explosion as our Solar System drifts through a giant cloud of gas and dust between the stars. Scientists analyzing Antarctic ice up to 80,000 years old discovered traces of iron-60 — a rare isotope forged in
The US Government has released a new trove of documents on cases of "unidentified anomalous phenomena" (UAPs)—many of which would have been described in the past as unidentified flying objects or UFOs—including photos, videos and reports of unexplained events sighted in the sky
Storm-driven sea floods are becoming more frequent as the climate warms, increasingly destroying the nests of threatened wader birds along the Baltic Sea coast. Waders are currently beginning their breeding season.
A remote island between Australia and Antarctica is showing signs of a dramatic climate transformation. Scientists found storms over Macquarie Island now unleash much heavier rainfall than they did decades ago, soaking ecosystems and altering fragile vegetation. The discovery
We are surrounded by computer-generated voices these days, from navigation systems and voice assistants to automated announcements. But how human do these voices actually sound? A recent study by the Max Planck Institute for Empirical Aesthetics (MPIEA) in Frankfurt am Main,
UC Davis researchers created brand-new psychedelic-like compounds by shining UV light on amino acid-based molecules. These compounds activated key serotonin receptors tied to brain plasticity and mental health benefits, but surprisingly did not cause hallucination-like behavior
If you travel around Australia, you will find an incredible diversity of lizards. The three-toed snake-tooth skink (Saiphos reticulatus), for example, is a peculiarly long and stumpy-legged reptile that burrows in rainforest and is covered in a brilliant orange and black-banded
Trying to solve quantum gravity is frustrating. We have made tremendous progress in quantum theory, but it seems that every time we find a new quantum technique, there's a reason it doesn't quite work with gravity. Take, for example, the case of quantum fluctuations and
Have you ever wondered if the simple building blocks of life could one day power our wearable electronics? Glycine, the simplest amino acid found in our bodies, has a superpower in its β-phase form: it is highly piezoelectric, meaning it can convert mechanical pressure into
RIKEN researchers have determined the molecular structure of an enzyme that occurs in fish. This could shed light on molecular processes in a wide range of marine organisms. The work is published in the Journal of Biological Chemistry.
The task of gently transporting a microscopic particle from one point to another along a winding path, and then bringing it back using nothing more than a single, compact chip is a challenge we set out to address in our new study, now published in Nature Communications.
The rover took a break from geochemistry to take stock of itself The post Perseverance Snaps a Selfie on Mars appeared first on Nautilus .
As the U.S. and other countries expand clean energy, large hydropower dams, often seen as a reliable renewable solution, can come with significant environmental and social costs if not planned thoughtfully.
One of the first steps in addressing health concerns is measurement. For firefighters, one health concern is that their gear commonly contains per- and polyfluoroalkyl substances (PFAS), also called "forever chemicals" because they don't break down naturally in the environment.
People in low-performing organizations are more likely to look to others working elsewhere to access new knowledge and practices, a new study shows. Those in high performing organizations are more likely to search for help from colleagues. The research in Public Management
A microscopic "plant destroyer" not only helped trigger one of the deadliest famines in modern history but also reshaped global agriculture and gave birth to an entirely new scientific discipline. Now, nearly 180 years after the Irish Potato Famine devastated Ireland and
Researchers at the Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures have conducted high-resolution investigations of the so-called cyanosphere, the "housing community" of cyanobacteria. The focus was on identifying previously unknown associated
British chemists David Klenerman and Shankar Balasubramanian joined French biophysicist Pascal Mayer in winning Spain's top science award on Wednesday for DNA sequencing research that helped combat coronavirus.
The selective conversion of alkenes into alcohols is a cornerstone of modern chemical synthesis, underpinning the production of pharmaceuticals, functional materials, and fine chemicals. However, conventional acid-catalyzed hydration reactions typically follow Markovnikov's
An international research team led by National Taiwan University has developed a new analytical framework based on Empirical Dynamic Modeling. This framework can quantify how response diversity varies over time using time-series data. Published in Nature Communications, the
Oxygen is a cornerstone of chemistry, largely because it is so good at building the organic molecules that make up our world. Some oxygen-based compounds called peroxides are famous for being highly reactive—they act like oxygen delivery trucks, transferring atoms to other
The twinkling stars in the night sky are not just beautiful to look at. Their flickering reveals something about the varying temperatures and densities in the layers of Earth's atmosphere, which refract the light as it travels toward us. Certain stellar remnants that emit radio
A new study published in the May 2026 issue of the American Economic Review and authored by an international group of researchers gives a different perspective on how production and financial networks are at interplay. The research develops a framework that integrates two key
Rice plants and Venus flytraps share something in common that was not scientifically documented until recently. Using a faint smell to lure caterpillars into a trap, rice plants killed early-stage fall armyworm larvae by trapping them in a spikelet, the part at the end of a
In physics, the spontaneous de-mixing of two substances is known as phase separation. It is an important mechanism in nature to create structure and patterns and typically requires some form of attraction between the constituents. Researchers at the Max Planck Institute for
Researchers have developed a technique to analyze how black holes "ring" when they collide and merge: one of the universe's most dramatic events. When black holes merge, the collision produces a new, larger black hole that "rings" like a plucked guitar string or a bell while it
Can we have higher yields and better taste? Using a natural extract from the fungus Pseudozyma aphidis, this method improves the firmness and natural sugar content of crops like tomatoes and melons while significantly boosting production. This discovery offers a practical path
Have you ever wondered how a fly manages to dodge you in a split second? Scientists have long been fascinated by the lightning-fast reflexes that help flies escape danger almost instantly. But despite decades of research, they still don't fully understand exactly how the brain
Two bald eagles hatchlings have been spotted in a nest in a Chicago park in what city officials believe is the raptors' first successful wild breeding in the Windy City in more than a century.
Debris is a growing threat to orbital infrastructure, and it’s only going to get worse as the number of launches increases
Sea levels are rising not only on average, but also in their seasonal fluctuations. This is a lesser-known trend that could have major consequences for mudflats, salt marshes and other coastal ecosystems. Researchers from the Netherlands and Flanders describe these findings in
Buffalo's legendary snowfall totals are largely the result of one unlucky geographic reality: the city sits east of the Great Lakes instead of west. Anyone who has lived through a winter in Buffalo, Cleveland or any snowbelt city knows that prevailing westerly winds pick up
A research team at TU Wien has succeeded in modifying known materials in such a way that they possess new, desirable properties. These materials are expected to find application in the field of thermoelectricity.
As digital nomads rethink where to live, researchers are exploring whether their choices can help close Europe's urban-rural divide. New research suggests the shift to remote working could support rural regions, but only where infrastructure and policy align.
Artificial intelligence (AI) systems affect many parts of daily life, including health care, education, and public policy, but the public has had few meaningful opportunities to participate in the development, governance, or modifications of AI systems, according to Tanusree
