Are we too dependent on technology?

What would happen if your computer crashed? What about if you lost your cellphone? If just thinking about these scenarios gives you anxiety, you’re not alone. Most of us rely so much on technology these days that losing it, even for a day, would be extremely inconvenient, and for some, life-altering.

YouTube rolling pay-to-watch channels.

YouTube says it has about one billion unique users to its service each month

YouTube has launched a trial scheme for paid channels on its website.

Under the pilot programme, a small number of content makers will offer the channels for subscriptions starting at $0.99 (£0.64) a month.

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).

Bitcoin: The world's first digital currency.

The world’s “first decentralised digital currency” promises financial salvation, but what is it and can it really deliver?

Dubai. Greece. Spain. Portugal. Italy. Cyprus. Ireland. The list of countries needing financial bailouts seems to go on and on. And that’s before you include those banks in the US, the UK and beyond that were “too big to fail”.

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 Fuel cell.

A fuel cell is an electrochemical cell that converts a source fuel into an electric current. It generates electricity inside a cell through reactions between a fuel and an oxidant, triggered in the presence of an electrolyte.

The Spark Gap.

A spark gap

A spark gap consists of an arrangement of two conducting electrodes separated by a gap usually filled with a gas such as air, designed to allow an electric spark to pass between the conductors. When the voltage difference between the conductors exceeds the gap's breakdown voltage, a spark forms, ionizing the gas and drastically reducing its electrical resistance.

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.
