Our Sun is not by far the only star out there that is capable of hosting planetary systems around their surface. There are at least a couple of hundred stars out there that have exoplanets around them. At least 400 of them have been identified until now, and chances are that thousands more exist. But astronomers have... |

In a groundbreaking, new research, experts at Japan’s National Institute of Advanced Industrial Science and Technology (AIST) have developed a new type of batteries, containing nickel and lithium, which can hold 3.5 times more energy than the average lithium-ion battery and is also much safer to boot. That is t... |

For a very long time, researchers have tried, unsuccessfully, to turn hydrogen into metal. This is known to be possible, and, probably, this form of the chemical is present on other planets, most likely gas giants, but it's impossible to obtain the material here on Earth. It has tremendously large pressure requi... |

Over the past few decades, there have been relatively few improvements in the technology employed in batteries, despite the emergence of lithium-ion cells and other similar devices. However, the capacity has remained roughly the same overall, and a breakthrough in the field has been long sought. Experts at the Univer... |

Bolivia has currently the largest lithium reserves in the world, approximately half of the total supplies in terms of quantity. This makes the country extremely important for the outside world, on account of the fact that the mineral is highly precious for the battery industry, as well as for the development of elect... |

Although they are highly reactive with other chemical elements and substances, lithium and beryllium do not bind together under normal atmospheric conditions. A team of Cornell researchers predict however that, while subjected to high levels of pressure, two of universe's lightest elements could, in fact, create... |

That's like having an 80 year old woman giving birth to a baby. The natural process of planetary formation, as astronomical observations proved in multiple situations, usually takes place in the first 10 to 100 million years of the star's life. However, it seems that this is not always the case. Old stars, ... |

Humans have been searching since ever for the secret of the deathless life and ageless youth. They linked longevity to pha-4 encountered in nematode worms, looked at the hormones of the queen bee or that of the naked mole-rat to see why she lives so much longer than the workers, but by now, no drug boosting longer-li... |

Lithium-ion cells are very popular when it comes to producing batteries for cell phones and mobile computing systems as the technology behind them allows manufacturers to create batteries with quite a long functioning time per charge and the production price is lower than in the case of other technologies. But it loo... |

The power of Superman is at our reach. Kryptonite, the green mineral that sapped the hero's power when exposed to it, has turned from fiction to reality, as a similar one has just been discovered by a team from the mining group Rio Tinto in a Serbian mine. "The real mineral is white and harmless. (...) it'... |
