Rare clues to Mesolithic life in Scotland's mountains add to evidence previously found in Perthshire and Dumfries.
A new study revealed that a drastic reduction of deaths of one of Africa's rarest primates, the Zanzibar red colobus (Piliocolobus kirkii), followed the installation of four speedbumps along a stretch of road where the species frequently crossed.
Eight months after mild COVID-19, one in ten people still has at least one moderate to severe symptom that is perceived as having a negative impact on their work, social or home life, according to a new study. The most common long-term symptoms are a loss of smell and taste and fatigue.
Sutures are used to close wounds and speed up the natural healing process, but they can also complicate matters by causing damage to soft tissues with their stiff fibers. To remedy the problem, researchers have developed innovative tough gel sheathed (TGS) sutures inspired by the human tendon.
Researchers explored the effect of solar climate interventions on ecology. The team emphasizes that greenhouse gas emissions reduction and conservation of biodiversity and ecosystem functions must be the priority.
Social distancing and lockdowns may have affected clinical researchers' ability to finish trials, researchers report. Study completion rates dropped worldwide between 13 percent and 23 percent, depending on the type of research sponsor and geographic location, between April and October 2020.
Scientists detail new work on NLRP3, an intracellular complex that has been found to participate in melanoma-mediated inflammation, leading to tumor growth and progression. By inhibiting NLRP3, the researchers found, they can reduce inflammation and the resultant tumor expansion.
Barcelona prosecutors are suing energy giant Endesa for the deaths of hundreds of birds electrocuted by its high-wire power lines, court documents show.
In an article published in the April 8 issue of Nature, the National Institutes of Health's Somatic Cell Gene Editing Consortium provided a detailed update on the progress of their nationwide effort to develop safer and more effective methods to edit the genomes of disease-relevant somatic cells and reduce the burden of disease caused by genetic changes.
Within multicellular organisms, cells build connections with each other forming cell layers that cover the surfaces of tissues and organs and separate structures in the body. For example, the skin forms a mantle around the entire organism, and the layer of cells lining the blood vessels creates a boundary between the bloodstream and tissues.
Teaching people to become entrepreneurs requires more than just passing on entrepreneurial skills, according to a team of Penn State Berks-led researchers. Would-be entrepreneurs also need to understand—and negotiate—the barriers that they might face.
Preliminary results from two experiments suggest something could be wrong with the basic way physicists think the universe works, a prospect that has the field of particle physics both baffled and...
How many species of birds are there in the world? It depends on whose count you go by. The number could be as low as 10,000 or as high as 18,000. It's tough to standardize lists of species because the concept of a "species" itself is a little bit fuzzy.
Ants react to social isolation in a similar way as do humans and other social mammals. A study by an Israeli-German research team has revealed alterations to the social and hygienic behavior of ants that had been isolated from their group. The research team was particularly surprised by the fact that immune and stress genes were downregulated in the brains of the isolated ants. "This makes the...
While studying genetic diversity in bumblebees in the Rocky Mountains, U.S., researchers from Uppsala University discovered a new species. They named it Bombus incognitus and present their findings in the journal Molecular Biology and Evolution.
Long before NASA's Perseverance rover touched down on the Red Planet on Feb. 18, one of its highest-level mission goals was already established: to seek out signs of ancient life on the Martian surface. In fact, the techniques used by one of the science instruments aboard the rover could have applications on Saturn's moons Enceladus and Titan as well Jupiter's moon Europa.
The hormone auxin is of central importance for the development of plants. Scientists at the University of Bayreuth and the Max Planck Institute for Developmental Biology in Tübingen have now developed a novel sensor that makes the spatial distribution of auxin in the cells of living plants visible in real time. The sensor opens up completely new insights into the inner workings of plants for...
You might not think an animal made out of stone would have much to worry about in the way of predators, and that's largely what scientists had thought about coral. Although corallivores like parrotfish and pufferfish are well known to biologists, their impact on coral growth and survival was believed to be small compared to factors like heatwaves, ocean acidification and competition from algae.
