What lit up the universe?

New research from UCL shows we will soon uncover the origin of the ultraviolet light that bathes the cosmos, helping scientists understand how galaxies were built.

The study published in The Astrophysical Journal Letters by UCL cosmologists Dr Andrew Pontzen and Dr Hiranya Peiris (both UCL Physics & Astronomy), together with collaborators at Princeton and Barcelona Universities, shows how forthcoming astronomical surveys will reveal what lit up the cosmos.

NASA’s NuSTAR Untangles Mystery of How Stars Explode

One of the biggest mysteries in astronomy, how stars blow up in supernova explosions, finally is being unraveled with the help of NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR).

The high-energy X-ray observatory has created the first map of radioactive material in a supernova remnant. The results, from a remnant named Cassiopeia A (Cas A), reveal how shock waves likely rip apart massive dying stars. (more…)

Searching for Cosmic Accelerators via IceCube

Berkeley Lab Researchers Part of an International Hunt

In our universe there are particle accelerators 40 million times more powerful than the Large Hadron Collider (LHC) at CERN. Scientists don’t know what these cosmic accelerators are or where they are located, but new results being reported from “IceCube,” the neutrino observatory buried at the South Pole, may show the way. These new results should also erase any doubts as to IceCube’s ability to deliver on its promise.

“The IceCube Collaboration has announced the observation of 28 extremely high energy events that constitute the first solid evidence for astrophysical neutrinos from outside our solar system,” says Spencer Klein, a senior scientist with Lawrence Berkeley National Laboratory (Berkeley Lab) and a long-time member of the IceCube Collaboration. “These 28 events include two of the highest energy neutrinos ever reported, which have been named Bert and Ernie.” (more…)

Ghostly Specter Haunts the ‘Coldest Place in the Universe’

At a cosmologically crisp one degree Kelvin (minus 458 degrees Fahrenheit), the Boomerang nebula is the coldest known object in the universe — colder, in fact, than the faint afterglow of the Big Bang, the explosive event that created the cosmos.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile have taken a new look at this object to learn more about its frigid properties and to determine its true shape, which has an eerily ghost-like appearance. (more…)

New Results from Daya Bay – Tracking the Disappearance of Ghostlike Neutrinos

Daya Bay neutrino experiment releases high-precision measurement of subatomic shape shifting and new result on differences among neutrino masses

The international Daya Bay Collaboration has announced new results about the transformations of neutrinos – elusive, ghostlike particles that carry invaluable clues about the makeup of the early universe.  The latest findings include the collaboration’s first data on how neutrino oscillation – in which neutrinos mix and change into other “flavors,” or types, as they travel – varies with neutrino energy, allowing the measurement of a key difference in neutrino masses known as mass splitting.

“Understanding the subtle details of neutrino oscillations and other properties of these shape-shifting particles may help resolve some of the deepest mysteries of our universe,” said Jim Siegrist, Associate Director of Science for High Energy Physics at the U.S. Department of Energy (DOE), the primary funder of U.S. participation in Daya Bay.

Ancient secrets which save your sex life

Man has two basic requirements – food and the sexual gratification. In order to enjoy a healthy lifestyle it is important to suffice these two requirements or else you can see chaos and disaster seen among the people. Food we all know and have been consuming since we were kids, however, this is not the case with sex. The desire to have sexual gratification comes when kids turn adolescent.

So, when it comes to sex life, there are different ways to enjoy it, however, if you look at the core, nothing really has changed since past centuries. Though the lifestyle has changed a lot and would continue changing, however, sex life seems to remain unchanged. You will find various ancients secrets, which can help you in having a good sex life. So how about checking some of the ancient secrets that can really save your sex life in the following paragraphs: (more…)

JPL, Masten Testing New Precision Landing Software

A year after NASA’s Mars rover Curiosity’s landed on Mars, engineers at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., are testing a sophisticated flight-control algorithm that could allow for even more precise, pinpoint landings of future Martian spacecraft.

Flight testing of the new Fuel Optimal Large Divert Guidance algorithm – G-FOLD for short – for planetary pinpoint landing is being conducted jointly by JPL engineers in cooperation with Masten Space Systems in Mojave, Calif., using Masten’s XA-0.1B “Xombie” vertical-launch, vertical-landing experimental rocket.

Newly Discovered Marine Viruses Offer Glimpse Into Untapped Biodiversity

Studying bacteria from the Baltic Sea, UA researchers have discovered an entire array of previously unknown viruses that barely resemble any of the known bacteria-infecting viruses.

Researchers of the University of Arizona’s Tucson Marine Phage Lab have discovered a dozen new types of unknown viruses that infect different strains of marine bacteria.  (more…)
