Most people in the United States, United Kingdom, Germany, France, and Italy clearly endorse military support for Ukraine. They overwhelmingly reject Russia's positions on territorial claims and restrictions on Ukraine's political sovereignty.
Researchers at the University of Konstanz have developed a gentle, contact-free method to collect liquids and remove them from microscopic surface structures. The method uses vapor condensation to generate surface currents that transport droplets off surfaces.
During spring, when queen bumblebees first emerge from hibernation to start their nests, they work incredibly hard foraging for nectar to fuel their new colonies. But then, as soon as their first workers are born, they seem to slack off.
Underground environments like soil and aquifers teem with microbial life. These tiny microbes play a big role in cycling nutrients and breaking down or transforming pollutants. However, scientists still struggle to reliably model how microbes grow and decay.
Many animals do something that still surprises researchers: females often mate with more than one male. This behavior—polyandry—has long raised a blunt question. Why divide offspring among multiple fathers, and does it help mothers or young survive?
As marine-terminating glaciers melt, the resulting freshwater is released at the seafloor, which mixes with salty seawater and influences circulation patterns. As the oceans warm, it's growing increasingly important to study this process.
For 21 years, between 1999 and 2020, millions of people worldwide loaned UC Berkeley scientists their computers to search for signs of advanced civilizations in our galaxy.

Challenging a 50-year-old narrative about Hawaiʻi's native birds, a new study from the University of Hawaiʻi at Mānoa found no scientific evidence that Indigenous People hunted waterbird species to extinction. Published in the journal Ecosphere, the research debunks this
In a new study, terrestrial bacteria-infecting viruses were still able to infect their E. coli hosts in near-weightless "microgravity" conditions aboard the International Space Station, but the dynamics of virus-bacteria interactions differed from those observed on Earth. Phil
Mergers and acquisitions can transform a company's future. For family businesses, those decisions hinge on more than financial calculations—they reflect how families balance control, identity, and risks.
Diversity among students and researchers is a common goal across academia. This has been driven by a desire to increase opportunities for the historically marginalized in higher education—moving away from the straight, white and male personification of academia.
One of the best-preserved ancient Roman homes on the Palatine Hill is opening to the public for the first time, albeit via a livestreamed tour of its hard-to-reach underground frescoes and mosaics.
The most exciting landmark scientific achievements don't happen without researchers sharing and collaborating with others outside their field. When people first landed on the moon in 1969, Neil Armstrong's first footsteps marked the realization of a century-long vision that
The night sky has long sparked wonder and curiosity. Early civilizations studied the stars and tracked celestial events, predicted eclipses and used their observations to construct calendars, develop maps and formulate religious rituals.
The expression "6-7" spread like wildfire last year, making its way outside the realm of usual adolescent slang and into the collective discourse, popping up at public sports events, in Halloween costumes and even in teachers' lesson plans.
Each year on the holiday that bears his name, Martin Luther King Jr. is remembered for his immense contributions to the struggle for racial equality. What is less often remembered but equally important is that King saw the fight for racial equality as deeply intertwined with
Seated on the stone floor of a medieval fortress in Italy's Tuscan hills, students rip thin, one-inch strips of fabric. They then knot the strips together to create extra chunky yarns. With these chunky yarns, they use oversized, thick crochet hooks, knitting needles and six
Evolutionarily speaking, the ultimate goal of a lifeform is to reproduce and stave off extinction. Many plants and animals have evolved unique tricks to do so. One of these tricks is mimicry, which might be used to trick other species into believing it is dangerous in order to
A team of New York University scientists has created a gear mechanism that relies on fluids to generate rotation. The invention holds potential for a new generation of mechanical devices that offer greater flexibility and durability than do existing gears—whose origins date
Clues from studies of ancient plants and animals have helped archaeologists pin down where the last Neanderthals found refuge, says columnist Michael Marshall
Once a picturesque garden beneath the sea, some stretches of the Florida Coral Reef have now become graveyards. Unburied coral skeletons stand as haunting remnants of the catastrophic marine heat wave that swept through in the summer of 2023, leading to the total functional
Bacteria can sneakily evade our best efforts at eradication by developing resistance to various pressures in their environment, for example, antibiotic-resistant bacteria stubbornly survive the usual deadly effects of antibiotics. The trade-off for developing a better defense
An international team of scientists has uncovered evidence glaciers in the Southern and Northern hemispheres were synchronous during the last ice age.
