New data from the largest 3-D map of our universe suggests we may be wrong about dark energy. One of the driving forces behind that evolution is also one of our age's biggest mysteries in physics: dark energy. Einstein abandoned the idea as his "greatest blunder" in the 1930s, as astrophysicist Ethan Siegal explains, but a constant dark energy would have vindicated him. "If true, it would be the first real clue we have gotten about the nature of dark energy in 25 years," Adam Riess, a Nobel laureate for his co-discovery of dark energy, told Quanta Magazine. "The idea that dark energy is varying is very natural," Paul Steinhardt, a Princeton University cosmologist, told the magazine.

Scientists from Tufts and Harvard created microscopic robots from human cells. AdvertisementScientists have created tiny biological "robots" from lung cells that they hope could one day travel around our bodies, regenerating damaged tissues and treating disease. Their research, published Thursday in the journal Advanced Science, raises new questions about how human cells assemble and work together. The same research team had previously created similar tiny robots, or xenobots, from cells sourced from embryos of the African clawed frog. AdvertisementAlhough they're created from human cells, Levin said the anthrobots didn't have a full life cycle and so aren't considered as fully-fledged organisms.

Scientists create tiny living robots from human cells

CNN —Scientists have created tiny living robots from human cells that can move around in a lab dish and may one day be able to help heal wounds or damaged tissue, according to a new study. The scientists used adult human cells from the trachea, or windpipe, from anonymous donors of different ages and sexes. Earlier studies had also shown that the cells can form organoids — clumps of cells widely used for research. “Nothing happened on day one, day two, day four or five, but as biology usually does, around day seven, there was a rapid transition,” she said. They are not made from human embryos, research that is tightly restricted, or genetically modified in any way, he said.

The seedy, culturally vibrant and rapidly modernizing Berlin of the 1920s was nicknamed “Chicago on the Spree.” That moniker sprang to mind recently during the premiere of a masterful and muscular new production of “Chicago,” directed by Barrie Kosky at the Komische Oper Berlin. “Chicago,” a “story of greed, corruption, violence, exploitation, adultery and treachery,” to quote the prologue, is the longest-running show currently on Broadway, but it got a very mixed reception when it opened there in 1975. Many of those early audience members were uncomfortable with Fred Ebb, Bob Fosse and John Kander’s use of musical showstoppers in the service of an amoral satire, and the show’s jerky and pastiche-like narrative technique. For his production, Kosky has gone back to the original concept of the show as a musical vaudeville with a heavy dose of bile and a dash of Brechtian alienation, while also embracing burlesque elements. Michael Levine’s dazzling set is outfitted with nearly 7000 light bulbs, which intelligently frame the actors, and the action, in frequently changing configurations that suggest a nightclub, a prison cell and a circus ring.
