They last a few milliseconds and are 500 million times more energetic than the sun. Since the first so-called FRBs (Fast Radio Bursts) were discovered in 2007, astronomers have broken their heads over the mysterious phenomenon. They are not yet sure where the signals come from and how they originate.
NASA engineers will be busy for the next 16 years. They face an enormous task, for which they have to develop all kinds of instruments, rockets and space suits. People have to go to Mars in the short term. Both chambers of the US Congress - the Senate and the House of Representatives - have just adopted the so-called NASA Authorization Act of 2017.
A rugged, cold world of mountains, plains, craters and gorges opens up on the new series of photos sent by NASA's New Horizons probe from the edge of the solar system. These photos were taken in the summer of 2015, but due to the enormous distance it takes a long time to download them here.
Football is increasingly becoming a game of technology and supervision, and that development is clearly visible during the World Cup in Russia. Thanks to an arsenal of surveillance cameras inside and outside the stadium plus drones, robots and AI image analysis software, goals, penalties and free kicks on the field are judged fairly.
Severe brain damage, poisoning, a serious lack of oxygen or diabetes can cause a person to fall into a coma. And then the question is whether he or she will ever wake up again. To date, people in a coma could not be helped in any way. But now researchers have succeeded in waking people out of their coma with electrical stimulation for up to a week.
So far, the only way to extend your life has been to treat the diseases we get when we get older, such as cancer, dementia, and atherosclerosis. But now researchers want to combat our aging process so that we can live in a body that never decays or gets sick.
In a large German study, scientists followed 20,000 men and women for eight years, until 2009, and compared their beer consumption with their weight and waist. The conclusion was that men with a big belly took more calories than they consumed, whether those calories came from beer or not. In men, the excess kilos on genetic grounds are mainly in the belly fat, and in women the sex hormones ensure that the majority of the fat ends up on hips, buttocks and thighs.

We like to be fascinated by prodigies who practice astrophysics even before they have outgrown diapers and already speak five languages fluently when they go to kindergarten. With the years it doesn't get any easier to place new things in the brain - but it certainly isn't impossible.
Sharks have sensitive senses Sharks are terrifying predators, but how exactly they locate and approach prey was until recently a mystery. However, researchers at the University of South Florida in the US have learned the secret during a six-year study. The scientists studied three species, the black-pointed shark, the hammerhead shark and the nurse shark, each in its own aquarium.
If very heavy programs are running on a telephone or computer - or many apps at the same time - this requires a lot of the memory (RAM) of the electronics and the processor power. If you restart the device, the control is moved from the operating system (such as Windows or iOS) to the so-called bootloader - the only program that is physically built into the computer.
Longest glass bridge © Getty Images Every glass plate of the 385-meter-long Zhangjiajie bridge in China can hold a 40-tonne truck. The glass is heated to 600 ° C and cooled quickly. This process compresses the mass, making the glass stronger. The strongest © Shutterstock The Rio-Antirrio Bridge in Greece can withstand the strongest forces.
We measure the energy value of food in a 'bomb calorie meter'. This consists of a sealed, insulated container that is immersed in water. In it we put food of which we want to measure the value, after which we close the container and fill it with pure oxygen. We light the food with a spark system.
What do we know Our worldview is largely based on the strong symmetries in the laws of nature. But in the early days apparently a billion and one matter particles were formed on every billion anti-matter particles. And because of this small imbalance, the universe still exists today. This imbalance is a break in what we call CP-symmetry in jargon.
PROBLEM: Solar flare sends plasma onto the earth. The sun runs from north to south magnetic field lines. At the equator, where the rotation of the sun is fastest, they are stretched the most. By being pulled, the field lines can break through the surface, so that huge clouds of electrically charged particles, plasma, are hurled in the direction of the earth.
