Are frozen goods really that bad for our health?

Wilhelm Conrad Röentgen, a physics professor at the University of Wurburg in Germany, was experimenting with electric current flow in a partially evacuated glass tube in 1895 and one night he noticed a glow caused by an unknown radiation. He named the phenomenon x-radiation and few months later he took the first x-ray photograph of a body part: the bones in his wife’s hand – and one can even see her wedding band. The first even x-ray image was of a key.

After winning the Nobel Prize in Physics in 1922, Carlsberg gave Niels Bohr a perpetual supply of beer. The brewing company had a pipeline running from the brewery to Bohr’s house, so that he could have fresh beer on tap all the time.

Researchers have shown that people who believe they've slept well and "deeply", even when they didn't, perform better on tests than those who're told they slept badly. So simply believing you had a good night's sleep can improve performance.

Israel-based company, StoreDot, has developed a battery made from a new material called nanodots that can charge a smartphone in just 30 seconds, and could be scaled up to charge an electric car within minutes. These special ‘nanodots’, which are artificial peptide molecules - about 2.1 nanometers in diameter - are released into the battery to rapidly increase its absorption and retention of power - almost like a sponge.

Dead or depleted batteries, especially cylindrical ones like AA or AAA batteries, can exhibit a unique behavior known as "bouncing" when dropped from a short height. This phenomenon is primarily due to changes in the battery's internal chemistry and physical properties as it becomes discharged.

Inside a battery, there are chemical reactions that generate electrical energy. As a battery discharges and its chemical energy is depleted, its internal chemistry changes. One of the changes that occur is a reduction in the pressure of gases within the battery. This decrease in gas pressure can make the battery feel lighter, contributing to its bounce.

As a battery discharges, its internal components, such as the cathode, anode, and electrolyte, unde ...

The Eshima Ohashi bridge in Japan has a 6.1% grade ramp up! The bridge is also the third largest ridge bridge in the world and stretches about a mile long with a height of about 144 feet.
