Taking a sample from just one part of a tumour may not give a full picture of its‘genetic landscape’, according to a study published in the New England Journal of Medicine.
The findings could help explain why attempts at using single biopsies to identify biomarkers to which personalised cancer treatments can be targeted have not been more successful. (more…)
ANN ARBOR, Mich.— Fifty million years ago, India slammed into Eurasia, a collision that gave rise to the tallest landforms on the planet, the Himalaya Mountains and the Tibetan Plateau.
India and Eurasia continue to converge today, though at an ever-slowing pace. University of Michigan geomorphologist and geophysicist Marin Clark wanted to know when this motion will end and why. She conducted a study that led to surprising findings that could add a new wrinkle to the well-established theory of plate tectonics – the dominant, unifying theory of geology. (more…)
ANN ARBOR, Mich.— Why is the universe magnetized? It’s a question scientists have been asking for decades. Now, an international team of researchers including a University of Michigan professor have demonstrated that it could have happened spontaneously, as the prevailing theory suggests.
The findings are published in the Jan. 26 edition of Nature. Oxford University scientists led the research. (more…)
*Findings further efforts to better predict geomagnetic storms in space*
UCLA researchers have explained the puzzling disappearing act of energetic electrons in Earth’s outer radiation belt, using data collected from a fleet of orbiting spacecraft.
In a paper published Jan. 29 in the advance online edition of the journal Nature Physics, the team shows that the missing electrons are swept away from the planet by a tide of solar wind particles during periods of heightened solar activity. (more…)
The theory that our universe is contained inside a bubble, and that multiple alternative universes exist inside their own bubbles – making up the ‘multiverse’ – is, for the first time, being tested by physicists.
Two research papers published in Physical Review Letters and Physical Review D are the first to detail how to search for signatures of other universes. Physicists are now searching for disk-like patterns in the cosmic microwave background (CMB) radiation – relic heat radiation left over from the Big Bang – which could provide tell-tale evidence of collisions between other universes and our own.
