3D Printers - Design of the future.

Many people are still unfamiliar with 3D printers, while those in the know are hailing them as a potential economic game changer. 3D printing is a method of making a solid object of almost any shape or size (depending on the size of the printer) by stacking up layers of material on top of each other.

The atmosphere of Jupiter is the largest planetary atmosphere in the Solar System. It is mostly made of molecular hydrogen and helium in roughly solar proportions; other chemical compounds are present only in small amounts and include methane, ammonia, hydrogen sulfide and water.

The Wimshurst influence machine is an electrostatic device for generating high voltages developed between 1880 and 1883 by British inventor James Wimshurst (1832 – 1903).

Erase your data from an old computer or phone.

If you're disposing of old documents such as bank statements and tax forms, security experts recommend shredding the paperwork so it can't be used by  identity theft.

New Earth-like planet found.

This artist's concept depicts Kepler-62f, a planet 1.4 times the size of Earth that circles in the habitable zone of its host star.

NASA's Kepler space telescope has discovered three exoplanets that may be capable of supporting life, and one of them is perhaps the most Earth-like alien world spotted to date, scientists announced (April 18/13).

A knockout mouse is a genetically engineered mouse in which one or more genes have been turned off through a targeted mutation.

Loophole in web found.

A website showing how the bug might work was set up by Mr Aboukhadijeh

Gigabytes of junk data could be dumped onto PCs via a loophole in web code, a developer has found.

The loophole exploits a feature of HTML 5 which defines how websites are made and what they can do.

The Superfluid.

Helium II will "creep" along surfaces in order to find its own level - after a short while, the levels in the two containers will equalize. The Rollin film also covers the interior of the larger container; if it were not sealed, the helium II would creep out and escape.

Superfluidity is a state of matter in which viscosity of a fluid vanishes, while thermal conductivity becomes infinite. These unusual effects are observed when liquids, typically of helium-4 or helium-3, overcome friction in surface interaction at a stage (known as the "lambda point", which is temperature and pressure, for helium-4) at which the liquid's viscosity becomes zero.

Eisenstein view of space-time is right.

Einstein's theory of general relativity predicted that the space-time around Earth would be not only
warped but also twisted by the planet's rotation. Gravity Probe B showed this to be correct.

Scientists traced the journey of photos from a gamma-ray burst that originated 7 billion light years away to determine the shape of space-time.

Bicycle and motorcycle dynamics

A computer-generated, simplified model of bike and rider demonstrating an uncontrolled right turn.

Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics is a branch of classical mechanics, which in turn is a branch of physics. Bike motions of interest include balancing,

Science of Liquid crystal.

Liquid crystals (LCs) are a state of matter that have properties between those of a conventional liquid and those of a solid crystal. For instance, an LC may flow like a liquid, but its molecules may be oriented in a crystal-like way.

10 most common ways hackers access corporate computer systems.

Hacking is often called the biggest danger to the economic security of the United States and the world.

So how do hackers get in the door? Alperovitch, who once worked for McAfee and is now the co-founder and CTO of the cyber security firm CrowdStrike, compiled a list for CNBC.com.

New computers installed with pre-infected viruses.

Cybercriminals have opened a new front in their battle to infect computers with malware - PC production lines.

How you can avoid being the next online victim.

Mat Honan, the technology reporter who was digitally disemboweled this past weekend, has revealed exactly how he was so spectacularly owned. His case, a cascade of security failures that involved four well-known companies, should be a warning to anyone overly reliant on cloud-computing services.

How to choose who can see you in Facebook’s chat sidebar.

Don’t want a certain Facebook friend to see you’re online? Sure, you could switch the entire Facebook chat sidebar into “offline” mode, but then you’d be invisible to all your friends.

The Photophone, also known as a radiophone, was invented jointly by Alexander Graham Bell and his then-assistant Charles Sumner Tainter on February 19, 1880, at Bell's 1325 'L' Street laboratory in Washington, D.C. Both were later to become full associates in

Hard disk drives undeleted data.

The ICO said two of the purchased hard drives had
enough information to steal someone's identity 

One-in-10 second-hand hard drives still contain the original user's personal information, suggests an investigation by the UK's Information Commissioner's Office (ICO).

The quick brown fox jumps over the lazy dog.

(Image is mirrored for readability.)

"The quick brown fox jumps over the lazy dog" is an English-language pangram, that is, a phrase that contains all of the letters of the alphabet. It has been used to test typewriters and computer keyboards, and in other applications involving all of the letters in the English alphabet. Owing to its shortness and coherence, it has become widely known and is often used in visual arts.

Neutrinos still faster than light.

Example of subatomic particle

A new experiment appears to provide further evidence that Einstein may have been wrong when he said nothing could go faster than the speed of light, a theory that underpins modern thinking on how the universe works.
