Insight into why the universe is dominated by matter and why we exist

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…

Testing for secure quantum communications 

China is set to launch a satellite that could form part of an unassailable, worldwide communications network. The 600 kg (1,300 pound) QUESS craft, launching sometime in August, will perform the first ever quantum experiments in space. A special crystal onboard will generate pairs of “entangled” photons that will be fired at labs in China…

‘Primitive Machine’ Within Great Pyramid of Giza Reconstructed

The ancient Egyptians created a simple yet elaborate system of blocks and grooves within the Great Pyramid of Giza to protect the King’s Chamber from tomb robbers. In an upcoming episode of the Science Channel’s “Unearthed,” that system comes to life via computer animations. In the episode, Egyptologist Mark Lehner describes the system for viewers,…

Mystery of Bizarre Radar Echoes Solved

More than 50 years after weird radio echoes were detected coming from Earth’s upper atmosphere, two scientists say they’ve pinpointed the culprit. And it’s complicated. In 1962, after the Jicamarca Radio Observatory was built near Lima, Peru, some unexplainable phenomenon was reflecting the radio waves broadcast by the observatory back to the ground to be…

Engines bend second law of thermodynamics

When French engineer Sadi Carnot calculated the maximum efficiency of a heat engine in 1824, he had no idea what heat was. In those days, physicists thought heat was a fluid called caloric. But Carnot, later lauded as a pioneer in establishing the second law of thermodynamics, didn’t have to know those particulars, because thermodynamics…

Bright Radio Flashes Reveal Missing Matter of the Universe

An international team of scientists using a combination of radio and optical telescopes identified the distant location of a fast radio burst (FRB) for the first time. This discovery has allowed them to confirm the current cosmological model of the distribution of matter in the universe. “The good news is our observations and the model…

Sleeping With Neanderthals

  Ancient trysts between Neanderthals and modern humans may have influenced modern risks for depression, heart attacks, nicotine addiction, obesity and other health problems, researchers said. The Neanderthals were once the closest relatives of modern humans. Scientists recently discovered that Neanderthals and modern humans once interbred; nowadays, about 1.5 to 2.1 percent of DNA in…

A cosmic ‘Rose’ for your Valentine

In celebration of the twenty-first anniversary of the Hubble Space Telescope’s deployment in April 2011, astronomers at the Space Telescope Science Institute pointed Hubble’s eye to an especially photogenic group of interacting galaxies called Arp 273. The larger of the spiral galaxies, known as UGC 1810, has a disk that is tidally distorted into a…

Gravitational Waves Detected. 

A century after being proposed by physicist Albert Einstein, scientists have made the first detection of gravitational waves — massive celestial objects on the move causing spacetime itself to ripple — a historic discovery that opens up an entirely new way of studying the cosmos. The detection was made by the twin LIGO interferometers on…

‘Gene editing’ go-ahead

UK scientists have been given the go-ahead by the fertility regulator to genetically modify human embryos. It is the first time a country has considered the DNA-altering technique in embryos and approved it. The research will take place at the Francis Crick Institute in London and aims to provide a deeper understanding of the earliest…

Links in Time and Space May Form the Universe’s Foundation

  In November, construction workers at the Massachusetts Institute of Technology came across a time capsule 942 years too soon. Buried in 1957 and intended for 2957, the capsule was a glass cylinder filled with inert gas to preserve its contents; it was even laced with carbon-14 so that future researchers could confirm the year…

Stars seem brighter this time of year

  As seen during Northern Hemisphere winter (or Southern Hemisphere summer), the stars seem brighter. Why? It’s partly because – on December, January and February evenings – the part of Earth you’re standing on is facing into the spiral arm of the galaxy to which our sun belongs. Consider the sky at the opposite time…
