Scientists are using funhouse images of faraway galaxies to learn how dark matter shaped the cosmos we see today.
Recently, one of the four 8.2-metre telescopes that make up the European Southern Observatory’s Very Large Telescope captured the brief but brilliant light of a distant explosion, a gamma-ray burst. The light from the burst passed through its host galaxy and another nearby galaxy before reaching Earth, providing Sandra Savaglio of the Max-Planck Institute for…
A rare and highly reactive iron mineral called green rust appears to have played an important role in ancient oceans, suggest new findings, which may have implications for the formation of Earth’s early atmosphere. The research team identified green rust in an Indonesian lake where conditions mimic those of the ancient oceans, and found the…
A controversial type of pesticide linked to declining global bee populations appears to scramble bees’ sense of direction, making it hard for them to find home. Starved of foragers and the pollen they carry, colonies produce fewer queens, and eventually collapse. The phenomenon is described in two new studies published in Science. While they don’t…
Poisoned-tipped arrows and jewelry made of ostrich egg beads found in South Africa show modern culture may have emerged about 30,000 years earlier in the area than previously thought, according to two articles published in the journal Proceedings of the National Academy of Sciences. The research shows that the 44,000-year-old artifacts are characteristic of the…
The World Flora catalog is being planned, to be comprised of scientific information and images of plant species worldwide. The project was created in part to help halt the loss of plant biodiversity around the world. Researchers at four institutions will look at historic data on known plants and review and update it before adding it to the catalog.
Scientists have taken a first early step toward escaping the limits of a technological principle called Moore’s Law by creating a working transistor using a single phosphorus atom. The atom was etched into a silicon bed with “gates” to control electrical flow and metallic contacts to apply voltage, researchers reported in the journal Nature Nanotechnology….
