Mystery

The legume family tree

(Penn State) The most comprehensive study of the family tree for legumes, the plant family that includes beans, soybeans, peanuts, and many other economically important crop plants, reveals a history of whole-genome duplications.

Archaeologists pinpoint population for the Greater Angkor region

(University of Oregon) Long-running archaeological research, boosted by airborne lidar sensing and machine-learning algorithms, finds that Cambodia’s Greater Angkor region was home to 700,000-900,000 people. The new estimate, made possible by a study designed at the University of Oregon, is the first for the entire 3,000-square-kilometer low-density region.

Adopt a Gargoyle and Help Fund the Rebuilding of Notre-Dame Cathedral in Paris

When most people think about adding a new creature to the family menagerie, images of “fuzzy” and “cute” spring to mind. Gargoyles and demons? Maybe not so much. But gargoyles and demons need love, too. “Love is like a tree,” wrote Victor Hugo his classic Hunchback of Notre Dame. “It shoots of itself; it strikes […]

Was North America populated by ‘stepping stone’ migration across Bering Sea?

(University of Kansas) A new study from the University of Kansas just published in the open-access journal Comptes Rendus Geoscience, may answer “one of the greatest mysteries of our time . . . when humans made the first bold journey to the Americas.”

Radio waves from famous FRB surprisingly long and late

Astronomers have managed to detect very long wavelength radio emission from a well-studied, repeating fast radio burst, called FRB 20180916B. What’s more, the longer wavelengths arrive 3 days after the shorter wavelength counterpart of the signal!

NASA’s Rover Makes Oxygen on Mars for the First Time

The growing list of “firsts” for Perseverance, NASA’s newest six-wheeled robot on the Martian surface, now includes converting some of the Red Planet’s thin, carbon dioxide-rich atmosphere into oxygen. A toaster-size, experimental instrument aboard Perseverance called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) accomplished the task on Tuesday. While the technology demonstration is just […]

Dutch Citizens are Using a “Doorbell” to Help Fish Pass Through the Canal Gate

Tasked with helping ensure Utrecht’s canals remain full of life, and convincing everyone it wasn’t an April Fools’ Day joke, two ecologists in the Dutch city have invented the world’s first “fish doorbell.” An underwater, live-streaming camera at the “Weerdsluis” lock door allows residents to ring a virtual doorbell heard by the local lock keeper […]

New amphibious centipede species discovered in Okinawa and Taiwan

(Tokyo Metropolitan University) Researchers from Tokyo Metropolitan University and Hosei University have discovered a new species of large, tropical centipede of genus Scolopendra in Okinawa and Taiwan. It is only the third amphibious centipede identified in the world, and is the largest in the region, 20 cm long and nearly 2 cm thick. It is also the first new centipede to be identified in Japan in 143 years, testament to the incredible biodiversity of the Ryukyu Archipelago.

Egg and sperm cell size evolved from competition

(Northwestern University) Using mathematical modeling, researchers considered a time very early in evolution when primordial species reproduced using external fertilization. In the model, bigger reproductive cells, or gametes, presented a competitive edge because they could hold more nutrients for a potential zygote. Smaller gametes, however, required fewer resources to make, which put less stress on the parent. Organisms evolved to specialize in large or small gametes, precursors to eggs and sperm.
