Astronomers using the Subaru Telescope have discovered 83 quasars in the distant Universe, from a time when the Universe was less than 10% of its present age. An artist’s impression of a quasar.

They can be millions or even billions of times more…

Using data from the LAMP (Lyman Alpha Mapping Project) instrument aboard NASA’s Lunar Reconnaissance Orbiter, planetary researchers have observed water molecules moving around the dayside of the Moon.

In 2010, the 28,140-year-old partial carcass of a woolly mammoth (Mammuthus primigenius), nicknamed ‘Yuka,’ was found in Siberian permafrost. Now a team of scientists in Japan has recovered the less-damaged nucleus-like structures from Yuka’s remains and visualized their dynamics in living mouse eggs (oocytes) after a procedure called nuclear transfer. Yamagata et al succeeded in observing…

Physicists from the Large Hadron Collider beauty (LHCb) Collaboration at CERN have discovered a previously unknown particle that consists of a charm quark and its antimatter counterpart, the charm antiquark. The mass and other properties of the new particle, ψ3(1D), place it squarely in the charmonium family that includes the better-known J/ψ meson, which was the first particle containing a charm…

Anti-inflammatory medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) and steroids are commonly used to treat various diseases. According to a new study, a colored extract obtained from the seeds of the avocado (Persea americana) — an important tropical crop that is rich in unsaturated fatty acids, fiber, vitamins B and E, and other nutrients — represents a potential source…

Pure ice is blue because ice absorbs more red light than blue light. Most icebergs appear white or blue when floating in seawater, but since the early 1900s explorers have reported seeing emerald green icebergs around certain parts of Antarctica. A new study published in the Journal of Geophysical Research: Oceans suggests that the iron content found in marine ice is sufficient to explain the unusual…
