The sperm whale (also called the cachalot) the largest toothed predator. Mature males average at 16 metres (52 ft) in length but some may reach 20.5 metres (67 ft), with the head representing up to one-third of the animal’s length. The sperm whale feeds primarily on squid, which it hunts at impressive depths, usually deeper than 2 km. Researchers have believed for some…

Planet Earth through the eyes of an Astronaut

On a clear day you can see forever (or at least form Havana to Washington, D.C.).

Col. Chris Hadfield is not your typical astronaut (as far as astronauts can be seen as typical). The first Canadian to walk into outer space, Hadfield caused sensation on social media channels on various occasions, be it after recording a song while surfing gravity in the ISS or when he showed us how to brush your teeth in micro gravity. He’s most popular posts…

A new proposed amendment in the UK would make a mockery of existing European shale gas regulation. If the new regulation would pass, it would allow fracking companies to put “any substance” under people’s homes and property and leave it there, as part of the Infrastructure Bill. The wording of the bill would also allow storing nuclear waste. Europe has much stricter…

The Pharaoh’s Snake: This Chemical Reaction looks like a Portal to Hell

Many chemical reactions are quite shocking, but this one is definitely something else. Take a look at the decomposition of Mercury(II) thiocyanate (Hg(SCN)2): Mercury thiocyanate is a white powder that looks pretty inconspicuous when you look at it. However, when you introduce heat (burn it), it produces a blue flame and creates a solid snake-like mass which seems to stem straight…

The US and India sign Space Agreement

India's Mars Orbiter Mission got straight down to work on arriving at the Red Planet.

We were telling you a while ago how India launched a probe towards Mars, and how it was successful in reaching the Red Planet’s orbit – a magnificent achievement for any country, let alone India, which is still a developing country. To make their success even more remarkable, they are the first country ever to successfully send a probe to…

Heart rate variability keeps the body in optimal shape

heartrate

The heart regularly speeds up or down its beating frequency to adjust to the body’s needs. Even in stable conditions (when you’re not particularly active or your active for a constant time), the amount of time between heart beats is variable. A team of doctors and engineers at Caltech’s Division of Engineering and Applied Science have now found a better way to assess…
