Arsenic-loving bacteria may help in hunt for alien life. 2 December 2010Last updated at 12:23 ET The bacteria slowly incorporated arsenic into their innermost workings The first organism able to substitute one of the six chemical elements crucial to life has been found. The bacterium, found in a California lake, uses the usually poisonous element arsenic in place of phosphorus. The find, described in Science, gives weight to the long-standing idea that life on other planets may have a radically different chemical makeup.

It also has implications for the way life arose on Earth - and how many times it may have done so. The "extremophile" bacteria were found in a briny lake in eastern California in the US. While bacteria have been found in inhospitable environments and can consume what other life finds poisonous, this bacterial strain has actually taken arsenic on board in its cellular machinery. The bacteria were found as part of a hunt for life forms radically different from those we know. As unexpected Continue reading the main story “Start Quote.

Space The universe can be a very strange place.

While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ? 273.15°C, where the motion of all particles stops completely. However, you can never actually cool something to this temperature because, in quantum mechanics, every particle has a minimum energy, called “zero-point energy,” which you cannot get below.

Remarkably, this minimum energy doesn’t just apply to particles, but to any vacuum, whose energy is called “vacuum energy.” One prediction of Einstein’s theory of general relativity is that when a large object moves, it drags the space-time around it, causing nearby objects to be pulled along as well.
