Old-looking galaxy in a young universe: Astronomers find dust in the early universe

Dust plays an extremely important role in the universe — both in the formation of planets and new stars. But dust was not there from the beginning and the earliest galaxies had no dust, only gas. Now an international team of astronomers, led by researchers from the Niels Bohr Institute, has discovered a dust-filled galaxy […]

Physicists offer a solution to the puzzle of the origin of matter in the universe

Most of the laws of nature treat particles and antiparticles equally, but stars and planets are made of particles, or matter, and not antiparticles, or antimatter. That asymmetry, which favors matter to a very small degree, has puzzled scientists for many years. New research by UCLA physicists, published in the journal Physical Review Letters, offers […]

Area-Specific Reestablishment of Damaged Circuits in the Adult Cerebral Cortex by Cortical Neurons Derived from Mouse Embryonic Stem Cells

An experiment, mice developed and operated Spanish, has allowed the connection of transplanted neurons in the adult brain. Adult stem cells demonstrate that a human organ can regenerate damaged A group of scientists from the Free University of Brussels has managed to repair first injury of cerebral cortex neurons by implanting generated from stem cells. One […]

Five days of eating fatty foods can alter how your body’s muscle processes food, researchers find

You might think that you can get away with eating fatty foods for a few days without it making any significant changes to your body. Think again. After just five days of eating a high-fat diet, the way in which the body’s muscle processes nutrients changes, which could lead to long-term problems such as weight […]
