Physicists create antimatter in record density

October 23, 2015

Physicists from Rice University and the University of Texas at Austin have found a new recipe for using intense lasers to create positrons — the antiparticle of electrons — in record numbers and density.

[...]

Although the positrons were annihilated in a fraction of a microsecond, the experiments have implications for new realms of physics and astrophysics research, medical therapy and perhaps even space travel, said Rice physicist Edison Liang, lead author of the study.

“There are many futuristic technologies related to antimatter that people have been dreaming about for the last 50 years,” said Liang, the Andrew Hays Buchanan Professor of Astrophysics. “One is that antimatter is the most efficient form of energy storage. When antimatter annihilates with matter, it becomes pure energy. Nothing is left behind, unlike in fusion or fission or chemical-based reactions.”

China to create world’s biggest super-collider

10:28pm, Oct 30, 2015

It seems size does matter as China starts work on the world’s largest super-collider – set to be twice the size of Switzerland’s Large Hadron Collider – which could help scientists answer question about how the universe works.

State-run media China Daily reported that construction of the collider would begin in 2020, in an attempt to increase understanding of the Higgs boson or ‘God particle’.

America doesn't do awesome stuff anymore...Thank you conservatives for fucking destroying America as a world power.


I'd rather join the isis and become a muslim then vote republican.

JB-9 jetpack makes spectacular debut flying around Statue of Liberty

The dream of personal flight took a great leap forward last week as Jetpack Aviation unveiled its JB-9 jetpack in spectacular fashion. Lifting off from a boat, inventor and aviator David Mayman flew the powerful, agile JB-9 around the Statue of Liberty, pausing to salute and pirouette before touching back down. Running on kerosene and using two vectored jet engines, the JB-9 can reach high speeds and altitudes and offers a flight time over 10 minutes, depending on pilot weight. We spoke at length with Mayman to discover how the JB-9 works and how long it'll be before we can buy one.

ORNL's hybrid device combines microscopy and mass spectrometry

• November 9, 2015

As occurs all too often in scientific analysis, if you want to investigate more than one aspect of a sample, then you almost always need a different tool for each examination required. How convenient it would be if a substance could be both microscopically examined and chemically analyzed at the same time. In this vein, researchers from the Department of Energy’s (DOE's) Oak Ridge National Laboratory (ORNL) have created a hybrid optical microscope/mass spectrometry-based imaging system capable of observing and analyzing specimens simultaneously.

New technique may make materials hotter than the Sun's core in 20 quadrillionths of a second

• November 15, 2015

If some people get impatient waiting for a soft-boiled egg to cook, that's nothing compared to a group of theoretical physicists at the Imperial College London. They've come up with a new method that could allow lasers to heat certain materials to temperatures hotter than at the Sun's core in 20 quadrillionths of a second. The new technique would reportedly be 100 times faster than the world's most energetic laser system at the Lawrence Livermore National Laboratory, California, and may one day have applications in future fusion research.

Scaling Shock Electrodialysis for Desalination

A team at MIT has come up with an innovative desalination approach that, unlike most traditional desalination systems, does not separate ions or water molecules with filters, which can become clogged, or boiling, which consumes great amounts of energy. Instead, the system uses an electrically driven shockwave within a stream of flowing water,...

CERN sets new high-energy collision record

• David Szondy
• November 26, 2015

The Large Hadron Collider (LHC) recently set a new record, as CERN announced that the world's most powerful accelerator had achieved the highest-energy collisions of heavy atomic nuclei. The Geneva-based laboratory says that on Wednesday at 11:15 am CET, the 27 km (17 mi)-long supercollider fired two counter-circulating beams of lead nuclei at one another and the results were recorded by the ALICE heavy-ion detector.
