A fossil lower jaw found in the Ledi-Geraru research area, Afar Regional State, Ethiopia, pushes back evidence for the human genus — Homo — to 2.8 million years ago, according to a pair of reports published March 4 in the online version of the journal Science. The jaw predates the previously known fossils of the […]Read more "Discovery of 2.8-million-year-old jaw sheds light on early humans"
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 […]Read more "Old-looking galaxy in a young universe: Astronomers find dust in the early universe"
Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists at EPFL have succeeded in capturing the first-ever snapshot of this dual behavior. Quantum mechanics tells us that light can behave […]Read more "First ever photograph of light as a particle and a wave"
he discovery that the human brain continues to produce new neurons in adulthood challenged a major dogma in the field of neuroscience, but the role of these neurons in behavior and cognition is still not clear. In a review article published by Cell Press February 21st in Trends in Cognitive Sciences, Maya Opendak and Elizabeth […]Read more "Newborn neurons in adult brain may help us adapt to environment"
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 […]Read more "Physicists offer a solution to the puzzle of the origin of matter in the universe"
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 […]Read more "Area-Specific Reestablishment of Damaged Circuits in the Adult Cerebral Cortex by Cortical Neurons Derived from Mouse Embryonic Stem Cells"
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 […]Read more "Five days of eating fatty foods can alter how your body’s muscle processes food, researchers find"
Each year, Science’s editors choose a singular scientific achievement as Breakthrough of the Year. Past winners have included the discovery of the Higgs boson, cancer immunotherapy, and the first quantum machine. This year’s winner captured the world’s attention and reminded us of the immense scope of human scientific accomplishment—as well as how far we have […]Read more "Breakthrough of the Year: The top 10 scientific achievements of 2014"
