Scientists from the École Polytenchnique Fédérale de Lausanne (EPFL), with the aid of colleagues from the Salk Institute for Biological Studies and the University of Lausanne, managed to improve the muscle constitution of mice by knocking out genetically a “co-repressor” of the DNA transcription process. The end product are mice that are faster, stronger and healthier – meet the new generation
Frogs are able to leap across huge distances, multiple times greater than their body length, however their leg muscles are only a fraction as powerful as they should be to support these kind of jumps. A new study by researchers from Brown University shows that this ability doesn’t come from leg muscles, but lies in their tendons which stretch and
Paleontologists have unearthed the remains of numerous whale fossils, dating back from seven million years ago, in Northern Chile. On further analysis it was revealed that the site in question is actually home to numerous other specimens, so far no less than 80 fossils have been recovered from the whale graveyard. “In 15 days, we have had almost 15 whales.
The rotifer is an extremely fascinating creature, mainly due to its wheel-like head, which also also earns it the name of “wheel animal”. A microphoto of a rotifer, which can be seen depicted above, earned the photographer, Charles Krebs, the first prize in the 2011 Olympus BioScapes Digital Imaging Competition. Rotifers are only 0.1–0.5 mm long, and are commonly found in freshwater environments. What
Conservationists are prepared to declare the Western Black Rhino officially extinct soon, after poaching killed off the remainder of already scarce wild specimens scattered around the area of Cameroon. Until 2000, ten wild specimens were still roaming free, however prized by poachers for the animals’ horns, used in traditional medicine practice by the local populace, even these few survivors have
Just a couple of days ago I was telling you about an ambitious and successful initiative to relocate black rhinos, but the situation is more dire than it appears at a first glance: the Western Black Rhino of Africa has been declared officially extinct, and two other subspecies are extremely close to meeting the same fate. The International Union for
The Komodo dragon is definitely one of the most impressive and dangerous creatures to roam the Earth. Reaching 3 metres and more than 70 kilos and delivering one of the most fatal bites in the reptilian world, it’s no wonder that it inspired so many legends and fears. However, it does not all end here: it seems that this modern
