After a NASA top official warned that China may stake a claim on the moon's resources. The spokesperson for the Chinese embassy said, "Outer space is not a w...
TUCKED in the Milky Way is cluster of stars which scientists estimate to be around 12billion years old. A new image from the Hubble Space Telescope released today shows a sea of stars near the cent…
Structural analysis of Cas12a2, a CRISPR-associated nuclease that nonspecifically cleaves ssRNA, ssDNA and dsDNA, reveals a complete activation pathway involved in the abortive infection system protecting cells against invasion.
Astronomers glimpsed a stellar nursery the -- Sh2-54 Nebula -- in a new light, thanks to the Visible and Infrared Survey Telescope for Astronomy in Chile.
As semiconductor devices become ever smaller, researchers are exploring two-dimensional (2D) materials for potential applications in transistors and optoelectronics. Controlling the flow of electricity and heat through these materials is key to their function…
An in vitro system that recapitulates temporal characteristics of embryonic development demonstrates that the different rates of mouse and human embryonic development stem from differences in metabolic rates and—further downstream—the global rate of protein s…
A fungus that infects salamanders contains multiple copies of the same "jumping genes", scientists have discovered. Jumping genes, called transposons, can "copy and paste" themselves and impact the organism.
The way electrons interact with photons of light is a vital part of many modern technologies, from lasers to solar panels to LEDs. But the interaction is inherently weak because of a major mismatch in scale: the wavelength of visible light is about 1,000 time…
A decline in disruptive science and technology over time is reported, representing a substantive shift in science and technology, which is attributed in part to the reliance on a narrower set of existing knowledge.
The rate of ground-breaking scientific discoveries and technological innovation is slowing down despite an ever-growing amount of knowledge, according to an analysis released Wednesday of millions of research papers and patents.
Utah State University biochemists Thomson Hallmark and Ryan Jackson, along with collaborators, published two seminal papers this week. Their findings describe the structure and function of a newly discovered CRISPR immune system that—unlike better-known CRISP…
In a recent study published in Nature Communications, an international team of researchers led by Stanford University used artificial intelligence (AI) to examine the formation of sand ripples and sand dunes of two distinct sizes on Mars. These formations mig…
