Pale Red Dot campaign reveals Earth-mass world in orbit around Proxima Centauri
Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than the Earth and is the closest exoplanet to us — and it may also be the closest possible abode for life outside the Solar System. A paper describing this milestone finding will be published in the journal Nature on 25 August 2016.

Fluorescent proteins from jellyfish that were grown in bacteria have been used to create a laser for the first time, according to a new study.
The breakthrough represents a major advance in so-called polariton lasers, the researchers said. These lasers have the potential to be far more efficient and compact than conventional ones and could open up research avenues in quantum physics and optical computing, the researchers said.

New findings that reveal why the universe is dominated by matter and why we exist will be presented by the international T2K Collaboration, a team a researchers who will demonstrate why matter and antimatter are different.
Stony Brook University physicist Professor Chang Kee Jung, a leading member of the T2K Collaboration, will present the results of the T2K findings and explain why they are significant to theories of particle physics and Bing Bang Cosmology.

Archaeology isn’t always the most interesting of subjects; not until there is some sort of jaw-dropping type of discovery, that is. The time they discovered the legendary lost civilization of the Monkey God, for instance. What we find of past civilizations, cultures and cities is astounding and eye-opening. It helps paint a much clearer picture of the world that existed before our time, and sometimes the history books just do not have it right. Here are some archaeological finds you may never have read about in history class.

What would happen to you if you went back in time and killed your grandfather? A model using photons reveals that quantum mechanics can solve the quandary—and even foil quantum cryptography
On June 28, 2009, the world-famous physicist Stephen Hawking threw a party at the University of Cambridge, complete with balloons, hors d’oeuvres and iced champagne. Everyone was invited but no one showed up. Hawking had expected as much, because he only sent out invitations after his party had concluded. It was, he said, “a welcome reception for future time travelers,” a tongue-in-cheek experiment to reinforce his 1992 conjecture that travel into the past is effectively impossible.
