Some inconvenient truths about biosignatures involving two chemical species on Earth-like exoplanets

Sen—A new study suggests that the search for life on planets outside our Solar System may be more difficult than previously thought. The study from the University of Toronto, led by Assistant Professor Hanno Rein from the Department of Physical and Environmental Science, finds the method used to detect biosignatures on exoplanets can produce a [...] Read more

The DNA sat nav: find your ancestor's home from 1,000 years ago

Tracing where your DNA was formed over 1,000 years ago is now possible due to a revolutionary technique developed by a team of international scientists led by experts from the University of Sheffield. The groundbreaking Geographic Population Structure (GPS) tool, created by Dr Eran Elhaik from the University of Sheffield's Department of Animal and [...] Read more

Quark quartet forms exotic particle

Particles called quarks are important building blocks of matter. They're usually found stuck together as triples or pairs to form bigger particles like the protons and neutrons that make up the core of an atom. Now scientists say quarks come in quartets, too. A new study confirms the existence of a strange kind of particle made from a cluster of [...] Read more

Herschel discovers mature galaxies in the young Universe

When galaxies kind, they accumulate mass by gravitationally attracting vast, external gas clouds. As the gas clouds enter the galaxy, they fall into haphazard orbits. These disordered paths lead to turbulence in the host galaxies, which can drive star formation. To investigate the internal conditions of forming galaxies James Rhoads and Sangeeta [...] Read more
