Scientists have shown that trauma can leave epigenetic marks - chemical changes that affect how DNA is expressed without altering its sequence. Basically, your traumatic experiences genetically affect your offspring. Scientists have recently focused on the long term after effects of trauma, finding them to be numerous and diverse. The offspring of traumatized people are at […]

Harmless bacteria turned deadly just 30 years ago – now, it kills 500.000 every year

It’s a truly terrifying story, and a truly terrifying disease. The flesh-eating culprit in question is called GAS, or Group A β-hemolytic streptococcus, a highly infective bacteria. Apart from causing the flesh-eating disease necrotizing fasciitis, GAS is also responsible for a range of less harmful infections. But like most bacteria, it was harmless at one point in its […]

Oligarchy vs Democracy Democracy is a pretty familiar term, at least it should be! Democracy is a form of government in which all eligible citizens participate equally (either directly or indirectly) in the proposal, development, and creation of laws. Technically, all citizens are equal – they all have one vote, they all have the same rights. Democracy […]

Three French students transformed a 3-D printer — a MarkerBot Replicator 3D printer, to be exact, into a tattoo machine! So we can now add “makes tattoos” to the impressive list of things 3D printers can do! It all started with an idea that came to Pierre Emm, a young student in France, while he […]

True Blood redux – artificial blood to be manufactured in factories

A few months ago we were telling you about the researchers from Transylvania, Romania, who developed artificial blood. Now, the production of blood on an industrial scale could become a reality as other researchers found a way to develop artificial blood from patients’ stem cells. Marc Turner, the principal researcher in the £5 million programme funded […]

I feel like a broken record – graphene is awesome at this, graphene is awesome at that… graphene is just awesome! A few months ago, we were telling you about the first graphene ear buds, which were really promising, but researchers still had a lot of work to make them commercially viable. Well, they’ve turned it up […]

NASA to conduct unprecedented twin experiment: one twin will spend a year circling the Earth, while the other stays grounded

Tue, Apr 15, 2014

It’s something that puzzled me for years now: consider a pair of identical twins; say, one gets a job as an astronaut and rockets into space. The other is also an astronaut, but he decides to skip this one and stay home. After a while, they reunite, but are they still identical? That’s exactly what NASA […]

Glow-in-the-dark roads make debut in Netherlands

They not only look awesome, but they may actually save a lot of power. Light-absorbing glow-in-the-dark road markings have replaced streetlights on a 500m (0.3 mile) stretch of a highway in the Netherlands; this is just a test, and if everything goes alright, then authorities will implement them over longer and longer sections. The design was […]

I don’t really use Bing all that often, but I think that they do some things significantly better than the competition. However, I don’t want to get into a discussion about search engines and all that, that’s not what this is about. When I was using Bing, I noticed that they add an awesome image […]
