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
Mitochondria generate most of the body's energy. Variations in their genetic material have long been linked to neurological disorders, metabolic syndromes, and cancers. However, most large-scale mitochondrial DNA (mtDNA) studies to date have focused on European populations,

A RIKEN researcher and his colleague have identified how genes are expressed in fish embryos when they first start using their own genetic material. If the same mechanisms apply to humans, they could shed light on developmental problems.
Funding uncertainties are pushing U.S. space scientists out of the field and putting existing and future space missions on the chopping block.

Can we use carbon to help decarbonize the world and transform the energy and chemical industries? Yes, it seems, but there are some key challenges to overcome first.
A smart toilet design introduced in rural Cambodia was supposed to change lives—keeping families safe and protecting the environment. However, while households reported that they liked the new system, a crucial piece was missing: using it correctly.
If "Batman" appears on the scene, we immediately become more altruistic: in fact, research conducted by psychologists from the Università Cattolica del Sacro Cuore, Milan, shows that the sudden appearance of something unexpected—Batman—disrupts the predictability of everyday
Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New modeling suggests that slow leakage of elements from Earth’s core into the mantle
A flying piece of cosmic rock or an alien threat? Comet 3I/ATLAS is hurtling through our solar system and captivating scientists and internet users alike, even prompting Kim Kardashian to ask NASA for answers.
After spending two college semesters in northern Thailand, Sarah Jongsma found herself back home in the rural Nevada town where she grew up, surrounded by everything familiar yet feeling strangely out of place.
Climate change will make monsoon storms in South Asia wetter and weaker, with more storms pushing further inland across India.
Once known to locals as "Bish Vegas" for its bustling pubs, bars and nightlife, Bishop Auckland in County Durham is now at the center of a very different story.
A team led by scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has engineered poplar trees to produce valuable chemicals that can be used to make biodegradable plastics and other products. The modified trees were more tolerant of high salt
As global efforts intensify around restoring coastal wetlands to curb climate change, a new JCU-led study published in Reviews of Geophysics is the first to link wetland restoration and carbon cycling with groundwater dynamics, showing that subsurface flows can tip the balance
Like other sectors of society, artificial intelligence is fundamentally changing how investors, traders and companies make decisions in financial markets. AI models have the ability to analyze massive amounts of data while reading company filings or news headlines almost
The CDC this week quietly changed its official language to suggest vaccines may cause autism, a claim that scientists say has no basis in evidence
In a discovery shaped by more than a decade of steady, incremental effort rather than a dramatic breakthrough, scientists from the National University of Singapore (NUS) and their collaborators demonstrated that great ideas flourish when paired with patience.
Cosmic rays are high-energy particles that constantly bombard Earth from space and are influenced by the sun's magnetic activity. When the sun is active, fewer of these particles reach Earth; when the sun is quiet, more are detected. Understanding these variations is essential
Astronauts strapped moss spores to the outside of the International Space Station for nine months - and most of them survived the challenging experience
Mosses thrive in the most extreme environments on Earth, from the peaks of the Himalayas to the sands of Death Valley, the Antarctic tundra to the lava fields of active volcanoes. Inspired by moss's resilience, researchers sent moss sporophytes—reproductive structures that
