Scientists Trap Antimatter

Core of the CMS, the world's largest superconducting magnet

 

Nuclear scientists at CERN, the world’s largest physics lab, have found a way to “trap” antimatter atoms for more than fifteen minutes using a super magnet.

Antimatter particles are elusive, because they are destroyed when they come into contact with matter. Every element has its equivalent in antimatter. Antimatter seems to have identical properties with matter, except it holds an opposite charge. For example, the scientists trapped antihydrogen, which behaves exactly like hydrogen, but with a negative charge instead of a positive charge.

 

 

 

Antimatter seems to differ from matter by its electric charge alone

Being able to maintain particles for such a long time is a huge breakthrough because it will give scientists the opportunity to study the mysterious particles closely.

“We went from two-tenths of a second to 1,000 seconds,” said American scientist Jeffrey Hangst, a spokesman for the ALPHA research team working at CERN.

Capturing antimatter will not only help scientists solve riddles of the universe. Many futurists believe that antimatter has the potential to be an extremely efficient energy source. Unfortunately, scientists are far from capturing enough antimatter to even begin harnessing it for potential energy.

Still, Hangst says that simply being able to capture antimatter “is a big step in demonstrating what we can do and where we can go.”

E-Coli slowly spreads to the US

Three people in the United States have been suspected of falling ill from e-coli after travelling to Germany where the bacteria first began to spread.
The Centers for Disease Control and Prevention may not confirm any details until the blood samples return. Although these suspected cases were not fatal, the outbreak first occurred in Germany and has proven deadly.
Over 1,600 people have been infected in Europe and reports show that 18 cases were fatal. Although Government officials are unaware of the exact source, they are instructing people to avoid raw vegetables.
Farmers, consumers, and officials are searching for explanations and looking at possible gaps in the food system. Fresh produce such as tomatoes, cucumbers, and leafy lettuce are proving to be threatening.
Officials are aware that they must improve the safety for consumers and the way they test. E-Coli has never been thoroughly tested in the United States, until now and scientists are learning to search for the right things.
The FDA has begun to set new standards for produce manufacturers and are forcing them to clean their produce thoroughly. They are instructing farmers to keep proper hygiene and to inspect their vegetables before selling or eating.
On Thursday, health officials stated that although the outburst has quickly spread throughout Europe, the United States should not be overly concerned.
