Since the 1970s, the idea of tweezers changed drastically for some people. Instead of using a pair of tweezers with a magnifying glass and a light attached to them, scientists have been using an entirely different machine called Optical tweezers. The goal of optical tweezers...
How are chemicals identified?
By: Reynold Conger
Some chemicals have similarities that can group the chemical with similar chemicals, but each chemical has several distinguishing characteristics. By looking at the chemical's characteristics, a chemist can identify the chemical. The process is called qualitative analysis. The oldest form of qualitative analysis is a...
Scientific first: Successful manipulation of antimatter
By: Terrence Aym
A group of groundbreaking, international scientists called the ALPHA team successfully manipulated antimatter and measured it for the first time in history. The team nudged anti-hydrogen atoms using a tool that emitted a microwave stream. Last June 2011, Jeffrey Hangst, of Denmark's Aarhus University and...

The nature of time is a puzzle that none in physics have been able to solve. But that doesn't stop physicists from moving ahead with their ever more exacting measurement of whatever time is—and they're entering territory that makes the old-fashioned atomic clocks look...

Chlorine is a strong oxidizing agent and is used in many toilet cleaning products. Even though chloride ions are necessary for human beings, elemental chlorine is extremely dangerous. When this toxic yellow-green gas (with concentrations above 30 ppm) is inhaled, it reacts with water and...
Is Time Real does Time Exist Time and Relativity is Time only Relative Absolute or Abstract Time
By: Christyl Rivers
Does time have to be non relative to be real? This question is begged by the title of this article. Einstein believed in relative time, but he could also conceive of both bicycles and cars. They do not mutually exclude one another, and Einstein had...

A rainbow, the multi-coloured bow shaped pattern that is often seen in the sky during or shortly after rainfall is caused by the refraction[1] and internal reflexion[2] of sunlight as it comes into contact with droplets of moisture in the atmosphere. Less commonly known is...

“Nomad” planets (also called “rogue planets”) are planets that are not attached to any particular star and are not part of any particular solar system. Scientists now believe that that there are more of these heavenly bodies in the Milky Way Galaxy...
Nomad planets of the Milky Way Galaxy
By: Christina Rodgers
A nomad planet is a rogue planet floating through space, rather than being locked in orbit around a star. In 2000, a group of Spanish astronomers reported planets up to 15 times the size of Jupiter in Orion. In 2011, astronomers reported 10 planets, around...

Many planets making their way through the cosmic void may be orphans. They do not seem to be attached to any identifiable parent star, which is odd when one considers the accepted wisdom for the formation of planets. Are there stars that have formed planets...
