Measuring the effect of gravity on antimatter
Measuring the effect of gravity on antimatter
Scientists at the University of Liverpool have measured for the first time the effect of gravity on antihydrogen – the antimatter counterpart of hydrogen – marking an important step in understanding how antimatter behaves. Whilst scientific evidence led scientists to assume that antihydrogen had exactly the same properties as hydrogen, it had not been proven.

Is antimatter anti-gravity?
Is antimatter anti-gravity?
Antimatter is strange stuff. It has the opposite electrical charge to matter and, when it meets its matter counterpart, the two annihilate in a flash of light. Four University of California, Berkeley, physicists are now asking whether matter and antimatter are affected differently by gravity as well.

New matter-antimatter difference
New matter-antimatter difference
27 Apr 2013 A subtle difference between matter and antimatter has been observed for the first time by the Large Hadron Collider beauty (LHCb) experiment at the European Organisation for Nuclear Research (CERN). The work forms part of studies to understand why the Universe only contains matter when it is believed that matter and antimatter were created in equal amounts at the time of the Big Bang.

Physicists, biologists unite to expose how cancer spreads
Physicists, biologists unite to expose how cancer spreads
Posted April 26, 2013; 01:00 p.m. by Catherine Zandonella, Office of the Dean for Research Cancer cells that can break out of a tumor and invade other organs are more aggressive and nimble than nonmalignant cells, according to a new multi-institutional nationwide study. These cells exert greater force on their environment and can more easily maneuver small spaces.

CERN reveals new matter-antimatter difference
The LHCb collaboration at CERN has made its first observations of matter-antimatter asymmetry in the decays of the particle known as the B0s. Matter and antimatter are thought to have existed in equal amounts at the beginning of the universe, but today the universe appears to be composed essentially of matter.

LHCb experiment observes new matter-antimatter difference
The LHCb collaboration at CERN observed the first matter-antimatter asymmetry in the decays of the particle known as the B0 s . It is only the fourth sub-atomic particle known to exhibit such behaviour. Matter and antimatter are thought to have existed in equal amounts at the beginning of the universe , but today the universe appears to be composed essentially of matter.

Researchers capture wasted heat, use it to power devices
Researchers capture wasted heat, use it to power devices
Imagine how much you could save on your electricity bill if you could use the excess heat your computer generates to actually power the machine. Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have taken an important step toward harnessing that heat and converting it for practical use.

A step toward optical transistors?
As demand for computing and communication capacity surges, the global communication infrastructure struggles to keep pace, since the light signals transmitted through fiber-optic lines must still be processed electronically, creating a bottleneck in tele networks. While the idea of developing an optical transistor to get around this problem is alluring to scientists and engineers, it has also remained an elusive vision, despite years of experiments with various approaches.

White-dwarf star, blown apart in 1604, now reveals new secrets
This composite of images from NASA's Chandra X-ray Observatory shows the remnant of Kepler's supernova in low-energy (red), intermediate-energy (green) and high-energy (blue) X-rays. The background is an optical star field taken from the Digitized Sky Survey. The distance to the object is uncertain, with estimates ranging from 13,000 to 23,000 light-years, but recent studies favor the maximum range.

Mars Science Lab update: What remains of Mars’ atmosphere is still dynamic
ANN ARBOR-Mars has lost much of its original atmosphere, but what's left remains active, according to recent findings from NASA's Mars rover Curiosity that involve a University of Michigan researcher. Rover team members reported diverse findings today at the European Geosciences Union 2013 General Assembly, in Vienna, Austria.

Study provides new insight into photosynthesis
Pigments found in plants and purple bacteria employed to provide protection from sun damage do more than just that. Researchers from the University of Toronto and University of Glasgow have found that they also help to harvest light energy during photosynthesis. Carotenoids, the same pigments which give orange color to carrots and red to tomatoes, are often found together in plants with chlorophyll pigments that harvest solar energy.

Latest results indicate new particle is Higgs boson
Latest results from CERN further reinforce that the particle discovered last year is a Higgs boson. Following the latest results from CERN scientist are more certain than ever about the identity of the particle discovered last year. "Still nothing conflicts with the idea it's a Higgs boson," said an Imperial scientist.

Green Pea galaxies could help astronomers understand early universe
ANN ARBOR-The rare Green Pea galaxies discovered by the general public in 2007 could help confirm astronomers' understanding of reionization, a pivotal stage in the evolution of the early universe, say University of Michigan researchers. Reionization occurred a few hundred million years after the Big Bang as the first stars were turning on and forming the first galaxies.

Shedding new light on enzyme crucial to life processes
Researchers at the University of Liverpool have revealed the crystal structure of a bacterial enzyme that offers clues on how electrons in the body move from one protein molecule to another. The movement of electrons is called electron transfer (ET) and is essential for all living organisms, as it underpins processes such as respiration, photosynthesis, and detoxification.

Another step toward quantum computers: Using photons for memory
Scientists at Yale University have found a new way to manipulate microwave signals that could aid the long-term effort to develop a quantum computer, a powerful tool that would revolutionize information processing through unprecedented speed and power. Like regular (classical) computers, quantum computers must be able to receive, store, and manipulate information in order to perform calculations.
