The oldest and thickest Arctic ice seems to be vanishing much faster than the younger, thinner ice at the edges of the Arctic ocean. The bright, white snow mass from the center is the perennial ice sea, which has survived for at least one year, while the larger, light blue area shows the full extent […]

A new study which analyzed Neanderthal DNA suggests that our close, now extinct relatives were on the point of dying off as a race well before humans made their appearance in Western Europe. The team of international researchers analyzed the mitochondrial DNA extracted from the bones of 13 Neanderthals, and studied its variation. Mitochondrial DNA is copious […]

I recently stumbled upon this absolutely dazzling chemistry experiment, and I just had to share it. What you will see is a pretty rare reaction in chemistry – an oscillation reaction. Three clear solutions are combined, and the color gradually changes to amber. Suddenly, the whole thing goes dark blue! Then it stays blue, reverts […]

A linguistic study found that people who regularly text message are less likely to accept new words, as opposed to those that read more traditional print media such as books, magazines, and newspapers. For the study, student volunteers were asked about their reading habits and text messaging frequency, and then presented with a set of […]

A team of researchers comprised of scientists at the NanoScience Center of the University of Jyväskylä, Finland, and at Harvard University, US, have shown through computer simulations a novel technique for generation nanomaterials. The whole process revolves around the extremely simple idea of twisting narrow graphene nanoribbons until they become rolled up into carbon nanotubes, […]

Astronomers at NASA‘s Chandra X-ray Observatory have come across a true astronomical oddity at the outskirts of the Milky Way, a stellar-mass black hole which exerts the fastest winds ever observed so far in its class – so fast that it rivals those blown by supermassive black holes, which often are billion times more massive.

For decades, classrooms were caught in a debate between creationism and evolution, and now, teachers will once again be caught in a somewhat similar discussion regarding climate change. Planting the seeds of ignorance Recently leaked documents from The Heartland Institute, a conservative think tank, revealed plans to pay a non-climate scientist to create school curricula […]

A team of German and American researchers have discovered four new species of tiny chameleons on the island of Nosy Hara, just off the northern coast of Madagascar, which considered one of the smallest reptiles known to man. Some are so small they can balance on the tip of a match. The  four new species […]

Australian scientists at University of New South Wales have successfully managed to build the first single-atom transistor, using a scalable, repeatable technique. The scientific community all over the world have already hailed this achievement as a highly important milestone, as single-atom transistors are considered as a critical building block for the eventual development of quantum computers.
