For more than 50 years since its discovery, the single-celled organism Tetrahymena thermophila has stirred curiosity around its seven sexes. UC Santa Barbara biologists have now found how the creature picks its gender from the slew, and apparently it’s not a matter of choice since the Tetrahymena gender distribution is as random as a game of roulette. The team [...]

The Iberian lynx is the only wild cat listed as  critically endangered by the International Union for Conservation of Nature (IUCN), numbering no more than 200 specimens, all of whom are entirely confined to southern Spain. Researchers from the Leibniz Institute for Zoo and Wildlife Research (IZW) in Berlin recently salvaged embryos and egg cells from a pair of captive [...]

While taking a walk with her parents on U.K.’s Isle of Wight (map) in 2008, Daisy Morris, who was then no more than 5 years old, came across blackened “bones sticking out of the sand”. Her family took the bones to paleontologist Martin Simpson at the University of Southampton, who, with the help of colleagues, [...]

For the first time in history, researchers have found microbes living deep inside Earth’s oceanic crust – the black basalts that make some 60% of our planet’s surface – potentially the largest habitat on our planet. Engineering and microbes Microbiologist Mark Lever is on board the Integrated Ocean Drilling Program’s research vessel JOIDES Resolution to [...]

Yep, spiders eat bats all across the world – except for Antarctica that is. Bats rank among the most successful groups of mammals, with the more than 1,200 species of bats comprising about one-fifth of all mammal species; aside for humans, they have very few natural enemies, and usually, their numbers are large enough to [...]

The Mariana trench is the deepest point on Earth; now, an international team of researchers found that the very bottom of the Mariana Trench, which lies almost 11 km beneath the surface of the Pacific Ocean, has high levels of microbial activity. No more than 30 years ago, we had a very different idea about [...]

During the geologic period called the Cambrian, life absolutely exploded, trying to fill all the ecologic niches suddenly made available. As a result, life took on many, and often times weird shapes – compared to what we know today, that is. Such is the case with Spartobranchus tenuis – a species previously unknown to science. [...]

Ok, so big news on the horizon: alien life forms have been found in a meteorite that recently crashed in Sri Lanka, on December 29, bringing along a new perspective on how we view the origin and movement of life. But… have they really? Well, sorry to burst your bubble ladies and gentlemen, but in [...]

A rather well rooted idea in evolutionary biology says that evolution itself is non-reversible. Simply put, once an organism has specialized certain traits, it can not return to its ancestral traits – this is commonly referred to as Dollo’s law. In a way, you could say that by looking at Dollo’s law, evolution isn’t ever [...]

Just a few days ago, we were telling you about the exciting new findings in lake Vostok – a new bacteria unlike anything else found so far retrieved from the lake sealed beneath 2 kilometers of ice for 1 million years. Now, the head of genetics laboratory at the Saint Petersburg Institute of Nuclear Physics [...]
