Researchers at the University of Michigan Life Sciences Institute and the Howard Hughes Medical Institute have determined how satellite DNA, considered to be “junk DNA,” plays a crucial role in holding the genome together. Their findings, published recently in the journal eLife, indicate that this genetic “junk” performs the vital function of ensuring that chromosomes ...
Transmissible cancers are incredibly rare in nature, yet have arisen in Tasmanian devils on at least two separate occasions. New research from the University of Cambridge identifies key anti-cancer drugs that could be trialled as a treatment for these diseases, which are threatening Tasmanian devils with extinction. The research also found that the two Tasmanian ...
Astronomers, using data from the Gemini and W. M. Keck Observatories in Hawai’i, have encountered a galaxy that appears to have almost no dark matter. Since the Universe is dominated by dark matter and it is the foundation upon which galaxies are built, “…this is a game changer,” according to Principal Investigator Pieter van Dokkum ...
Living abroad can clarify your sense of self, according to new research by a team of social scientists at Rice University, Columbia University and the University of North Carolina. The new research also shows that living abroad leads to clearer career decision-making. They found living abroad increases “self-concept clarity” — the extent to which individuals’ beliefs about ...
Ancient human footprints found off Canada’s Pacific coast may be 13,000 years old, according to a study published March 28, 2018 in the open-access journal PLOS ONE by Duncan McLaren and colleagues from the University of Victoria, Canada. Humans are believed to have migrated from Eurasia to North America during the last ice age, which ended around 11,700 ...
Parts of the Amazon rainforest previously thought to have been almost uninhabited were really home to thriving populations of up to a million people, new research shows. Archaeologists have uncovered evidence that there were hundreds of villages in the rainforest away from major rivers, and they were home to different communities speaking varied languages who ...
Astronomers are back in the dark about what dark matter might be, after new observations showed the mysterious substance may not be interacting with forces other than gravity after all. Dr. Andrew Robertson of Durham University presented the new results to the European Week of Astronomy and Space Science in Liverpool. Three years ago, a ...
With X-ray imaging at SLAC’s synchrotron, scientists uncovered a 6th century hidden medical text translation of a book by the Greek-Roman doctor Galen. The words had been scraped off the parchment manuscript and written over with hymns in the 11th century. An influential physician and a philosopher of early Western medicine, Galen of Pergamon was ...
An international team of physicists, including researchers at MIT, have reported the first results from an underground experiment designed to answer one of physics most fundamental questions: Why is our universe made mostly of matter and not antimatter? According to theory, the Big Bang should have produced equal amounts of matter and antimatter — the ...
For now, there are just a few things researchers and students at the University of Kansas want people to dig about the new baby Tyrannosaur fossil they recently excavated in Montana’s Hell Creek Formation. First off, it’s a “fabulous” complete section of the upper jaw with all of its teeth intact, along with bits of ...
