New class of star-stripped super-Earths discovered

Astrophysicists have discovered a new class of exoplanets whose atmospheres and volatile elements have been blown away by the star they’re orbiting. Their findings help cover a previously uncharted gap in planetary populations, and offers valuable insight for locating new worlds to colonize.

Who says incandescent bulbs have to waste energy: MIT design is more efficient than LEDs

Though incandescent light bulbs have been used to light homes for more than a hundreds years, and still do so in most of the world, these are ridiculously inefficient. This has prompted many governments to completely phase-them out, among which the E.U., Australia, Canada, Russian, as well as the United States. Their place has been taken over by fluorescent bulbs (CFLs), and the even more efficient LEDs. A team at MIT, however, has a bright idea that might revamp the unfavored bulbs. They’ve designed a new sort of incandescent bulb that uses a photonic crystal to recycle the waste energy. The resulting bulbs could be more power and light efficient than anything on the market right now.

What an underground nuclear explosion looks like

One this day, 53 years ago, the Lawrence Livermore National Laboratory detonated a thermonuclear device 194 meters below the Nevada desert. Why? Well, the government at the time thought blowing up a nuclear bomb underground sounded like a good idea if you want to excavate a mine. It’s a lot quicker than drilling with a lot machines. After all, mines are made using thousands of tonnes of dynamite. Why not take a shortcut and nuke the damn thing. The problem, of course is radiation. But how can you have people work in a mine if it’s contaminated with radiation, right? The logic escapes me as well.

Nuclear battery that uses water-based solution lasts longer and is more efficient

Though betavoltaics – battery technology that employs radiation as a means of power generation – has been around since the 1950s, developments thus far haven’t been the most promising. This may set to change after researchers at University of Missouri reported they’ve devised a nuclear-assisted battery, which works in a watery environment, that both lasts longer and is more efficient. The

Trees in Chernobyl aren’t dying and this is a problem

Some thirty years after Chernobyl’s nuclear plant meltdown that caused an international incident, scientists have yet to assess the full blown damage the radioactive disaster has caused. While the rest of the world has moved on, ever since the disaster the area surrounding the former nuclear plant has remained largely unchanged, even the plants and trees there seem to have

Veggie-based chemical protects against lethal radiation exposure

Researchers at Georgetown University Medical Center have found that a chemical compound derived  from cruciferous vegetables such as cabbage, cauliflower and broccoli has significant protective properties against gamma radiations, even when the subject is exposed to lethal doses. Previously, the same compound was found to have curative properties against cancer. Guess someone should have told the Hulk to eat his veggies. The compound

The 2018 manned mission to Mars will use poop as radiation shielding

Eccentric  millionaire Dennis Tito – better known for being the first tourist astronaut in space – announced late last month that he has set-up a manned mission to Mars called Inspiration Mars set to put the first man and woman into Martian orbit by 2018. As audacious as the plan might seem, Tito claims that the technology required to perform

NASA discovers surprise energy belt surrounding Earth

A ring of radiation that scientists knew nothing about fleetingly surrounded our planet last year, before being blown away by a powerful interplanetary shock, researchers say. Astronomic intuition Usually, whenever NASA launches a spacecraft, they wait weeks or even months to finely tune all its instruments. It’s a rite of passage that all shuttles (and rovers) have to pass through;

Mars radiation safe for human expeditions, Curiosity finds

In a new monumental find, Curiosity data readings suggest that radiation levels on the surface of Mars are very much similar to those in sub-orbital Earth. This means that astronauts or marsonauts can indeed set foot on the red planet, albeit for a limited amount of time. The findings came after the Curiosity rover, still only three months into its

X-raying a 120 million year old bird

Using a new X-raying technique and device, based on synchrotron radiation, scientists have been able to  map the pigmentation of creatures dead for million of years just by reading the traces metals in fossils left. “Every once in a while we are lucky enough to discover something new, something that nobody has ever seen before,” says Roy Wogelius, a geochemist

Intense Gamma Ray blast indeed traced back to supermassive black hole

We previously reported about an incredible gamma ray burst triggered by a black hole, so powerful that nothing like this was observed before, or even dimmed possible. A recently published paper in the journal Science sheds more light on the subject. A typical gamma ray burst commonly occurs when massive stars explode due to collisions with other stars or simple

The 8 coolest ways the Earth might be destroyed

We’ve all seen at least one movie in which our planet is destroyed, but most of them were quite repetitive and kind of uninteresting. Our planet deserves so much more! Black holes Well, it seems the more we understand things about black holes, the more we find out things we don’t know, and the more we fear them. Let’s just
