The fact that ecosystems change is nothing new. What is new, however, is the speed and scale at which new species communities are emerging as a result of climate change. Processes that once unfolded over centuries or even millennia are now being observed within just a few decades.
Polar oceans may play an important role in storing carbon and supporting biodiversity, but current science and policy frameworks are not yet ready to fully recognize their potential.
Cornell researchers have designed a new, faster form of two-photon fluorescence imaging for observing cell metabolism in real time, a method that could enable quicker screening of new therapeutic treatments. The findings were published Sept. 4 in Science Advances. The co-lead authors are former postdoctoral researcher Lu Ling, Ph.D. '20, and doctoral student Jack Crowley, M.S. '22.
Flu season is off to an early start in some parts of the U.S., data shows. In a typical year, U.S. flu activity starts building in late fall β typically in October or November β and peaks between December and February. This year, flu activity is currently low but rising nationwide: During the week ending Sept. 26, 3.4% of respiratory samples tested by clinical labs were positive for flu, according to Centers for Disease Control and Prevention (CDC) data. That's about seven times the rate that was seen at the same point last year. About 0.5% of samples tested positive during the week ending Sept. 27, 2025."This particular year, it appears to be starting early β like right now," Dr. William Sc...
A new study of 4,200 adolescents revealed that cyberbullying rarely occurs in isolation; it almost always functions as an extension of physical and verbal aggression already present in the school environment. The study, conducted at the Federal University of SΓ£o Paulo (Unifesp) in Brazil, mapped students' involvement in bullying and found that the lines between victims and perpetrators often blur in a cycle of violence spanning both the physical and digital worlds.
Filmmaker and outdoorsperson Quinn Barabash recently made headlines when he found a swordfish carcass nearly two meters (6.6 feet) long on the remote shores of Haida Gwaii in northern British Columbia.
The European nightjar (Caprimulgus europaeus) is a nocturnal migratory bird that travels between Europe and southern Africa each year. However, its wings are not only used for long-distance journeys. When hunting insects, the nightjar must be able to slow down, turn sharply and fly at low speeds. Researchers at Lund University have now shown how this trade-off is reflected in the bird's flight mechanics. The study is published in the journal PLOS Biology.
Genetic analysis revealed that several seeds from a batch sold as Sidra were not, in fact, Sidra; their genetic profile was closer to that of Batian, a Kenyan variety.
Depression may not be one biological condition, but several distinct patterns of brain activity hiding under the same diagnosis. Researchers studying 263 people with depression identified five brain profiles, each showing different patterns of communication between brain regions and associations with symptoms such as anxiety, trauma, and substance abuse.
AI is being integrated into our work at a growing rate. Andreas Bergqvist, a Ph.D. student at the Department of Information Technology, has teamed up with colleagues to investigate how AI, automation and robotization affect work engagement.
A Jupiter-sized world just 7.5 light-years away is cloudy, chemically complex and, it turns out, more like home than anyone expected. Using the James Webb Space Telescope, Brittany Miles, assistant astronomer at the University of Arizona's Steward Observatory, led a team that spent 11 hours staring at WISE 0855, the coldest known brown dwarf, collecting a spectrum of its light every 15 minutes.
Scientists have created a new family of materials whose behavior can be tuned by changing their metallic "recipe"βopening new possibilities for uses including gas storage and sensing.
Today, the discussions of sports analytics in the 2011 movie "Moneyball" often seem quaint. The idea of a team using data to find players who may be more valuable than meets the eye (and less expensive) no longer surprises anyone.
Scientists have demonstrated a remarkable new antenna that resembles a lightsaber, using a laser to create a tunable beam of plasma capable of transmitting radio waves. The technology could revolutionize wireless communications by allowing antennas to change their size and direction on demand, with promising applications in satellites, radar, and space exploration.
Finding a single cancer cell in a tube of blood is a bit like finding a needle in a haystack. As researchers seek to detect ever-smaller and rarer targets, from viruses to circulating tumor cells in blood, the demand for ultrasensitive, robust sensors that are practical for real-world samples continues to grow.
Localized pitting corrosion can cause sudden failure in aluminum components even when overall corrosion rates are low. Steam coating offers a water-vapor-based route to protective boehmite films, but processing simultaneously changes film thickness, surface morphology, crystallinity and substrate defects.
A strange chemical signature in old Hubble observations may point to a planet that formed after its star had already died. Astronomers found unusually high levels of niobium around the white dwarf HS 0209+0832, suggesting some of the starβs expelled material may have assembled into a new gas giant. TESS data also hints at a Jupiter-sized planet orbiting just 3.7 million miles from the star.
When a dying star runs out of fuel and sheds its outer layers, its remaining core can become an approximately Earth-sized, extremely dense stellar remnant called a white dwarf. For a white dwarf that is not strongly rotating or magnetized, there is a well-known upper mass limit of about 1.4 times the mass of the sun, known as the Chandrasekhar limit.
Feeling secure in a relationship is not only about how people connect with their partners today. It may also depend on how confident they are that the relationship will continue into the future. Feelings of closeness, trust and connection, together with a sense that the relationship is stable and has a future, can shape how people experience their romantic relationships.
The threat of cyberattacks against American agriculture and food systems is growing, and Washington State University researchers are helping to lead a call for a national consortium of land-grant universities to study and combat the threat.
For highly fragile quantum information systems, the ability to store quantum information is vitalβbut also challenging. Quantum information is transported in particles of light called photons, which often must be temporarily paused (or "stored") while other, slower quantum operations catch up. This storage must be performed on microchips as small as 1 centimeter (0.4 inches)βa distance covered by light in a few trillionths of a second. Storing photons for a microsecond would represent a massive leap forward for the capabilities of quantum chips.
Rocks in the asteroid belt rotating at ultra-fast speeds suggest our understanding of asteroid structure might be wrong
Episodic lava fountaining is a rare volcanic behavior in which repeated, hours-long bursts of molten lava and gas are spewed from volcanic vents, with quiet pauses lasting days to weeks between episodes. These lava fountains have been observed in active volcanoes in places like Hawaii, Iceland and Italy, but researchers still do not fully understand what starts, sustains or stops these individual fountain episodes.
Most covid-19 cases are caused by a particular type of variant, but do we need to worry every time a new one emerges?
