Science, engineering, and discovery — the research and breakthroughs that matter.

High above the fields of the Morven Sustainability Lab, drones equipped with heat and light sensors are changing what it means to farm smarter. This month, researchers and students from the University of Virginia, NASA and the University at Buffalo tested drone technology by flyi

When plants are attacked by herbivores or pathogens, they must respond rapidly while also preparing for potential future attacks. Calcium, a cellular second messenger, and the plant hormone jasmonic acid play important roles in this response. Within seconds of an injury, the plan

Young people leaning on AI chatbots for emotional support or personal advice are significantly more likely to struggle with serious emotional problems, feel isolated and doubt that they truly matter to others, a new uOttawa study warns.

Jupiter hosts more than 100 moons, with most attention focused on the four Galilean moons: Io, Europa, Ganymede and Callisto. This is primarily due to their active geology, including Io being the most volcanically active planetary body in the solar system and Europa having a vast

Despite the importance and dominance of angiosperms ("flowering plants") in the current ecosystem, it is rather surprising that we know so little about their origin and early evolution. Paleobotanists have been making efforts to decipher these enigmas. Unfortunately, their effort

Despite protections, blue whales remain endangered, primarily because of the risk of collisions with ships. MBARI's Blue Whale Observatory uses a suite of technologies to study these animals and their primary food source, krill, in the Monterey Bay region. The findings from this

Museums around the world now have a new tool to distinguish real ancient clay artifacts from fakes. The research team at UC San Diego's Scripps Institution of Oceanography, led by postdoctoral scholar Yoav Vaknin, found a way to distinguish the magnetism that clay materials acqui

Forecast storms in the Grand Canyon on Monday threatened efforts to find more than a dozen people missing after flash floods over the weekend, the National Park Service (NPS) said, with two bodies already recovered.

The cause of the huge floods and debris flow on the border between Nepal and Tibet, which have caused hundreds of deaths, appears to have been an ice avalanche—the result of a huge piece of a glacier collapsing and cascading down the mountain more than 1,000 meters (3,281 feet) t

Welcome back to our series on Interstellar Travel, where we look at the many proposals made for sending missions to the stars since the dawn of the Space Age. In our first installment, we examined how Cold War-era developments in nuclear weapons and rockets paralleled advances in

Astronomers using the James Webb Space Telescope have identified one of the most distant exploding stars ever confirmed. The supernova, SN 2023aeaf, was found at a redshift of 3.195—so far away that its light has been traveling for roughly 11.7 billion years. The study, published

Two widely used zero-calorie sweeteners, sucralose and stevia, may have effects that linger far longer than the sweet taste itself. In mice, researchers found that both sweeteners altered the gut microbiome, reduced beneficial compounds produced by gut bacteria, and changed the a

Two SUNY Polytechnic Institute (SUNY Poly) College of Business faculty members are exploring how integrating ethics and values throughout accounting and business education can better prepare students to recognize and prevent fraud in the workplace.

Harvesting tall fescue above annual bluegrass seed heads could help reduce contamination and seed-cleaning costs. Preliminary Oregon research found that cutting at 28 centimeters (11 inches) rather than 5 centimeters (2 inches) reduced annual bluegrass collected with the crop wit

Europe's water and climate resilience is under increasing pressure, with degraded soils, drained catchments and the loss of wetlands intensifying droughts and contributing to more destructive floods. In response, the EU-funded projects SpongeBoost, SpongeWorks and SpongeScapes ha

The cost of playing community sports in Australia is far higher than previously understood, with a new national study led by Federation University finding families spend an average of $4,567 per child each year to keep their children playing sports.

Transitioning an aging perennial forage seed stand into annual cropping can be difficult, particularly when the original crop persists or weeds establish after termination. Preliminary Canadian research suggests cover crops could help by suppressing regrowth and weeds, retaining

Australia's coral reefs are in relatively good condition compared with coral reefs globally, although coral cover on Australian reefs has declined over the past 40 years—reflecting the global trend, a major new report has found.

Ocean plastic pollution is accidentally on the menu for southern giant petrel chicks. Even small nibbles of it may affect their physiology during development, according to a study from the University of California, Davis, and Argentina's National Research Council (CONICET).

Targeted drug delivery directly to the liver has unlocked major breakthroughs across medicine, but constructing the chemical key to enter liver cells remains complex and costly. Today, researchers at Kumamoto University, in collaboration with the National University of Singapore,

Communication between cells in plants, animals and humans takes place via specialized connecting structures. An international team led by biologists from Heinrich Heine University Düsseldorf (HHU) and involving the University of Tübingen has now discovered that the regulation of
