Every day, billions of people travel from their homes to work, schools, health care facilities, restaurants, public venues and other destinations. The complex patterns that shape how people move between these different locations are broadly referred to as "human mobility."
A team of astronomers has discovered a third planet orbiting the star Beta Pictoris. The new planet, Beta Pictoris d, is 100 times fainter than Beta Pictoris b—the first planet discovered in the same system—and is among the lightest exoplanets ever imaged from the ground. After
A cave in the interior of Paraná state in Brazil contains a "climate archive" that enabled Brazilian researchers to reconstruct the history of extreme rainfall in Brazil's South Region over the past 7,500 years. Their findings revealed that the frequency of these events in the
Astronomers have used the ages of more than 155,000 stars in the Milky Way to independently estimate the age of the universe, and their findings may be good news for the standard cosmological model. The new research was reported in a paper submitted to the arXiv preprint server
In the aftermath of the devastating July 4, 2025, floods that took 139 lives in Central Texas, an associate professor at The University of Texas at Austin set out to make a new type of outdoor flood alarm: a low-tech, loud alarm that anyone could "set and forget"—just like a
It's the final week of the 2026 FIFA Men's World Cup. Over the last month, there have been plenty of highs and lows both on and off the pitch, from the overnight popularity of Cape Verde's goalkeeper Vozinha and the Norwegian row to the questionable use of Video Assistant
Solar eclipses are a rare and brief opportunity for scientists to gather data on everything from the physics of the sun to air pressure in the upper atmosphere
When extreme drought strikes, drier grasslands receive the greatest productivity benefit from biodiversity. By contrast, forests did not show the same context-dependent pattern under drought, according to a new global synthesis of 75 biodiversity experiments. Researchers from
Generative AI chatbots capable of writing emails and computer code, translating, organizing a trip or coming up with gift ideas are now readily available, prompting some to ask whether human brainpower could suffer for lack of use.
As interest in clean hydrogen power grows, so does the need for safe storage and transportation materials. One such material, vanadium, is a leading candidate because it readily absorbs hydrogen and allows it to move through its crystal structure. However, hydrogen displays
Heavy smoke from several large wildfires blazing in Canada and Minnesota is expected to engulf large swaths of the Midwest and Northeast U.S. this week, exposing millions of people to dangerous air pollution.

Four nearby white dwarf stars have been discovered hiding in plain sight beside brighter red dwarf companions. Hubble's ultraviolet observations finally revealed the long-hidden stellar remnants, including one just 25 light-years away that took nearly three decades to confirm.
Going to the cinema, visiting museums, or attending concerts may do more than entertain. Researchers found that older adults who regularly participated in cultural activities tended to have bodies that functioned like those of people about three years younger. They believe
Elephants can communicate with other elephants across distances of up to five kilometers (3 miles) by producing sounds that travel through the air. However, they have a second way of sending signals: seismic waves traveling through the ground. These vibrations are transmitted
Radicalization is a complex process, influenced by many variables that interact to varying degrees. AI scientist Mijke van den Hurk investigated whether artificial intelligence could help unravel this intricate interplay. She defended her Ph.D. thesis cum laude on June 29.
A deadly fungus has wiped out amphibian populations around the globe, yet some mysteriously recover. Researchers discovered that survivors develop powerful immune defenses while they are still tadpoles, giving them a head start before the fungus can attack after metamorphosis.
A new Aotearoa New Zealand study has found that nitrate concentrations in drinking water are associated with an increased risk of preterm birth, even at levels well below the current drinking water standard. The study, published in Environmental Research, analyzed 735,831
Chimpanzees showed a remarkable attraction to crystals, choosing them over ordinary stones and studying them with intense curiosity. The results suggest that the same unusual features may have fascinated early humans long before crystals had any practical use.
Why do countries go to war? While economic, military and geopolitical factors are often part of the answer, researchers have also pointed to exclusionary nationalism—the belief that one's own nation is superior to others. One observable trace of such sentiment is language: As
In an innovative gas fermentation process, reducing the concentration of carbon dioxide was found to significantly improve microbial production of the biodegradable plastic poly[(R)-3-hydroxybutyrate]. Researchers found that hydrogen-oxidizing bacteria grown under safe,
A new synthesis report, titled "Ecological Characterisation of Peatlands and Coastal Lagoons in Europe," has been published to support the assessment, monitoring and restoration of European wetlands under EU environmental legislation. The report was prepared in response to a
Astrobiology has long been split into two camps: a search for "biosignatures" and a search for "intelligence." These look for very different things, but they also leave a huge gap in between. It took 3.5 billion years for us to go from the first microbe to a civilization that
A new study found that chewing sugary gum after eating nitrate-rich vegetables or drinking beetroot juice helped the body produce more beneficial nitrite, leading to a temporary drop in blood pressure. Researchers hope the discovery will lead to healthier ways to enhance the
The mystery of why some amphibian populations recover following outbreaks of a deadly fungus has been solved in a new study led by University College London (UCL), ZSL and Imperial College London.
Last week, the U.S. software company Turnitin revealed 53.6% of Australian tertiary education submissions run through its system used some form of AI in the period from October 2025–April 2026. The company, whose plagiarism-detection technology is widely used in universities,
