Image credit: Yoshiki Matsuoka.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. Image credit: Yoshiki Matsuoka. Supermassive black holes are some of the most powerful objects in the Universe and are found in the centers of galaxies. They can be millions or even billions of times more…

Researchers ‘Revive’ Woolly Mammoth Cell Nuclei

Yamagata et al succeeded in observing the signs of the biological activity of 28,140-year-old mammoth nuclei in mouse oocytes. In this image, proteins that form chromosomes (red) and proteins that form dividing spindles (green) gather around a mammoth cell nucleus (upper right) in the mouse oocyte. Image credit: Yamagata et al, doi: 10.1038/s41598-019-40546-1.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…

PHYSICS

New Charmonium Particle Discovered

One of the first heavy-ion collisions with stable beams recorded by LHCb. Image credit: CERN.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…

Avocado Seed Extract Shows Anti-Inflammatory Activity

Dabas et al explored the anti-inflammatory potential of colored avocado seed extract. Image credit: Tookapic.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…

GEOLOGY

Study: Color of Green Icebergs is Caused by Iron-Oxide Minerals

Close-up view of an iceberg near Mawson Station, November 20, 1988, much of it covered by snow. At the far left is bubbly blue-white glacier ice; the center of the picture shows the clear, dark green, bubble-free marine ice. The boundary between glacier ice and marine ice is nearly vertical. Image credit: Warren et al, doi: 10.1029/2018JC014479.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…
