Making new friends has its challenges, even for birds. Researchers at the University of Cincinnati found that monk parakeets introduced to new birds will "test the waters" with potential friends to avoid increasingly dangerous close encounters that could lead to injury. They
When ultraviolet light hits ice—whether in Earth's polar regions or on distant planets—it triggers a cascade of chemical reactions that have puzzled scientists for decades.
The European Space Agency's Euclid mission—designed to map the geometry of the dark universe with unprecedented precision—continues to deliver its first scientific insights. The Euclid Consortium has published a fresh set of seven scientific papers based on data from the Euclid
Imagine trying to predict wind patterns as air flows across a landscape. It's a straightforward task over a flat plain—but becomes more complex when the terrain shifts to jagged mountain ranges. Here, wind does not simply sweep over peaks; it is deflected, slowed, and forced
Only two weeks after fertilization, the first sign of the formation of the three axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as gastrulation, a flat and featureless sheet of cells folds into a living blueprint for
Personalized learning is a very effective teaching method, but its potential is limited due to resource constraints. In a small, in-person class, instructors can walk around, engage with students individually, adjust lessons and adapt their teaching to match each learner's
A new study challenges the idea that language stems from a single evolutionary root. Instead, it proposes that our ability to communicate evolved through the interaction of biology and culture, and involves multiple capacities, each with different evolutionary histories. The

The countries participating in the UN Climate Change Conference (COP30), currently taking place in Brazil, must cancel fossil fuel concessions in order to keep the Paris Agreement alive. This is the main message of a paper published in the journal Nature and signed by experts
While you might assume the Nullarbor Plain is a vast expanse with not much to see, a recent discovery has stunned scientists.
A team of researchers has confirmed stars ring loud and clear in a "key" that will harmonize well with the science goals and capabilities of NASA's upcoming Nancy Grace Roman Space Telescope.
The inside of giant planets can reach pressures more than one million times the Earth's atmosphere. As a result of that intense pressure, materials can adopt unexpected structures and properties. Understanding matter in this regime requires experiments that push the limits of
Humans bring gender biases to their interactions with Artificial Intelligence (AI), according to new research from Trinity College Dublin and Ludwig-Maximilians Universität (LMU) Munich.

Why do no two human faces look quite the same? Although we all follow the same biological blueprint, our features—the curve of a lip, the angle of a nose, the breadth of a jaw—diverge in endlessly subtle ways.
Exposure to housing hardship before the age of 5 may influence "housing insecurity" in early adulthood, according to Rutgers-led research.

Researchers from The University of Texas at Dallas' Center for Advanced Pain Studies (CAPS) and their colleagues have made a fundamental discovery about a key mechanism that enables nervous system connections to strengthen.
About 4.5 billion years ago, the most momentous event in the history of Earth occurred: a huge celestial body called Theia collided with the young Earth. How the collision unfolded and what exactly happened afterward has not been conclusively clarified. What is certain,
A mysterious swarm of earthquakes that occurred near the Greek island of Santorini in early 2025 was caused by rebounding sheets of magma slicing through Earth's crust, according to a new study by an international team involving a UCL (University College London) researcher.
Researchers in the Blavatnik Institute at Harvard Medical School have opened a new window into understanding the development of antibiotic resistance in bacteria.
New work pinpoints origins for the planet Theia, whose ancient collision with Earth likely produced the moon

Anyone walking through the Tarumã neighborhood in Curitiba (the capital of the state of Paraná, Brazil) today may find it difficult to imagine the area as it was in the past. Between the buildings, racetrack, and the city's largest shopping mall, streams, open fields, and
Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate—a NAND gate (short for "NOT AND")—in a soft material using only beams of visible light. The discovery, published in Nature Communications, marks a
In most narratives, the story of evolution is the story of organisms emerging from the ocean and eventually populating the land. But for some species, that evolution also involved a return trip. Dozens of major mammal and reptile groups ultimately made their way back to the
Although present in very small amounts, selenium (Se)-based compounds play important roles in protecting the body from oxidative stress, regulating thyroid hormones, strengthening the immune system, and even detoxifying heavy metals. As we begin to understand more about the
In a new study published in Nature Physics, researchers have demonstrated that quantum light, particularly bright squeezed vacuum (BSV), can drive strong-field photoemission at metal needle tips.
While it is well known that climate change is heating the world's oceans, it was thought that the deep sea was safe from its effects—until now. Researchers have discovered that a rapidly warming part of the Atlantic is leading to the heating up of Arctic Ocean depths.
Books about AI, Mars and infectious disease were among our top reads this year.
Hurricane Melissa devastated Jamaica in late October, killed dozens in Haiti and forced nearly three-quarters of a million Cubans to evacuate. The death toll across the region is still unknown—but Melissa will go down as one of the strongest storms ever recorded.
By now, Americans know the strange math of minting: Each penny costs about 4 cents to make. Chances are you have some in a jar, or scattered among pockets, purses and car ashtrays.
Across the world, workers are increasingly anxious that artificial intelligence (AI) will make their jobs obsolete. But the evidence from research and industry tells a very different story. AI is not taking over the workplace. Instead, it's quietly reshaping what human work
Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences have reported new experimental results that advance our understanding of reaction dynamics and exotic nuclear structures of weakly bound nuclei.
The electroreduction of carbon dioxide (CO2) into valuable chemicals and fuels typically operates under alkaline or neutral conditions, but the carbonation side reaction causes carbon loss. In addition, the main product is formate, which requires additional treatment such as
