In recent years, citizen science methodology has gained significant momentum and is becoming increasingly important in large-scale ecological and conservation research. By involving volunteers, it enables a level of spatial and temporal coverage that would often be unattainable
Since their discovery in the 1950s, metallocenes—chemical compounds where a metal atom sits "sandwiched" between two carbon rings—have been at the heart of organometallic chemistry research, finding applications in catalysis, materials design, energy, sensing, drug delivery and
The French Riviera may look like an unlikely place for a tsunami disaster, but scientists warn the threat is far more real than most people realize. Historical events and new modeling show that destructive waves have already struck the Mediterranean coast — and could hit again
Evapotranspiration is a critical link between water, energy, and carbon. Scientists need to understand it well to accurately predict weather, droughts, streamflows, and even carbon emissions.
Reptiles have been growing armor in their skin on and off for hundreds of millions of years, but scientists never fully understood how it evolved. A massive new evolutionary study shows these skin bones appeared independently in multiple lizard groups rather than coming from a
Researchers have built an ultra-sensitive sensor capable of detecting unimaginably small amounts of energy — below one zeptojoule. The breakthrough relies on fragile superconducting materials that react to even the slightest temperature change. This level of precision could
Men with a strong sense of entitlement are three times more likely to commit "stealthing" during sex, according to a new University of the Sunshine Coast study. Stealthing, which has been criminalized in most Australian states over the past five years, is a form of sexual
Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already doing useful work. These sensors measure fields, forces and motion so small that ordinary background noise can drown them out. Some sensors are already in
New research from a Texas A&M College of Agriculture and Life Sciences doctoral graduate could help producers better protect poultry flocks from disease outbreaks while reducing costs.
Examination of pigeon bones from Late Bronze Age Hala Sultan Tekke, Cyprus indicates they were already semi-domesticated as early as c. 1400 BCE, pushing back direct evidence for pigeon domestication almost 1,000 years and challenging perceptions of the birds as opportunistic
