Humanized Yeast: Scientists Create Yeast With Important Human Genes

Daran-Lapujade’s lab took human DNA (in red) encoding core functions in muscle cells and inserted it into the DNA (chromosomes in purple) of a yeast cell (in yellow). The humanized yeast can be used as a tool for medical studies, for example in drug screening and cancer research. Credit: Ella Maru Studio / Pascale Daran-Lapujade …

Scientists Solve a 120-Year-Old Mystery: How Did the Monstrous Plesiosaurs Swim?

Artist’s concept of a plesiosaur. Plesiosaurs are characterized by four uniform flippers. A new study reveals how plesiosaurs swam underwater Plesiosaurs, who lived around 210 million years ago, adapted to living underwater in an unusual way: their front and hind legs evolved to become four uniform, wing-like flippers over time. Dr. Anna Krahl examined how …

Scientists Glimpse The Earliest Dark Matter Ever Observed in The Universe

What little we know of dark matter comes from calculations based on the glow of surrounding galaxies. The further away we look, however, the dimmer that starlight gets, making it harder to see the subtle influence of this most mysterious of forces.   Now a collaboration between astronomers from Japan and the US has found …

“Space is for everyone”: Meet the scientists trying to put otherworldly images into words

New photos from the James Webb Space Telescope let earthlings see farther into space than ever before. The kaleidoscopic images inspire awe and wonder and maybe even a bit of comforting perspective. But what if you’re blind? Some of the fixes for people who can’t see images are more helpful than others, according to blind …

Scientists create world’s first ‘synthetic embryos’

Researchers have created the world’s first “synthetic embryos” in a groundbreaking feat that bypassed the need for sperm, eggs and fertilisation. Scientists at the Weizmann Institute in Israel found that stem cells from mice could be made to self-assemble into early embryo-like structures with an intestinal tract, the beginnings of a brain, and a beating …

Cosmic Buckyballs Could Be The Source of Mysterious Infrared Light

Scientists may have just tracked down the source of some mysterious infrared glows detected emanating from stars and clouds of interstellar dust and gas. These Unidentified Infrared Emission (UIE) bands have baffled scientists for decades; according to a theoretical new work, at least some of these bands can be produced by highly ionized buckminsterfullerene, more …

In DNA, scientists find solution to building superconductor that could transform technology

Credit: Pixabay/CC0 Public Domain Scientists at the University of Virginia School of Medicine and their collaborators have used DNA to overcome a nearly insurmountable obstacle to engineer materials that would revolutionize electronics. One possible outcome of such engineered materials could be superconductors, which have zero electrical resistance, allowing electrons to flow unimpeded. That means that …
