Researchers at MIT and elsewhere have significantly boosted the output from a system that can extract drinkable water directly from the air even in dry regions, using heat from the sun or another source. The system, which builds on a design initially developed three years ago at MIT by members of the same team, brings the process…

Over 100 years ago, Nikola Tesla figured out technologies that we today are still unable to understand. In the late 1800s, Nikola Tesla talked about antigravity technology, flying saucers powered by specific Tesla Coils and ‘Ether’ which was acted upon by the life-giving creative force. “I have worked out a dynamic theory of gravity in…

Sailing through the smooth waters of vacuum, a photon of light moves at around 300,000 kilometers (186,000 miles) a second. This sets a firm limit on how quickly a whisper of information can travel anywhere in the Universe. While this law isn’t likely to ever be broken, there are features of light which don’t play by the same…

The ability to control different aspects and activities with magnetic fields is no longer restricted to the mischief of comic book villains. Using synthetic biology to figure out just what neurons do has always been a tricky task, because it has been limited by requiring invasive surgery (optogenetics) or slow on-off kinetics (drugs). But…

It has been detected previously that animals shed DNA, known as environmental DNA (eDNA), from their bodies into the environment. It was also previously detected in water, snow and soil, but not in the air. Now, scientists have found that human and animal DNA can be collected from air too. Scientists said this study can prove…

Many like to point out the evil that is going on in the streets, in the boardrooms and in the halls of power in Washington, but often some of the most horrific crimes that are occurring in society are taking place in the scientific laboratories. For years, the U.S. government funded the use of “fresh” aborted fetuses in experiments…

A new analysis shows that methanol fuel cells are more efficient at producing electricity than hydrogen fuel cells. Fuel cells use hydrogen – the most abundant element in the universe – to produce clean and efficient electricity to power cars, trucks, buses and ships, as well as even homes and businesses. Hydrogen is considered the…

According to Albert Einstein’s theory of general relativity, black holes are uninhabitable chasms of spacetime that end in a “singularity,” or a mass of infinite density. It’s a place so bleak that even the laws of physics break down there. But what if black holes aren’t so forbidding? What if they are instead some kind of intergalactic…

Sir Isaac Newton, one of the most famous scientists of recorded history, left behind a large body of work that is still vital in our understanding of the world today. However, as with many public intellectuals, he also had plenty of work that was never shared with the public, even after his death. Now, for the first time ever, some…

From a series of questions asked by children and answered by specialists, we present the following interesting piece. Why do we see different colours when we close our eyes? — Anais, aged 7 Hi Anais, thanks for your great question! Please be aware that seeing colours when we close our eyes is totally normal. It doesn’t mean…
