Alpha Centauri A, the sun’s twin, seems to posses a strange quality similar to the sun. Both stars contain a cool layer in the atmosphere. This has puzzled scientists time after time. The corona, or outer atmosphere, is millions degrees hotter than the photosphere, or sun’s surface. The odd part though, is that a cool layer is squished in between the corona and photosphere. This layer is called the chromosphere and can get as cold as 7,300 degree Fahrenheit(4,000 degree Celsius) . This is 3,000 degree Fahrenheit difference from the photosphere( which is around 10,000 degree Fahrenheit or 6,000 degree Celsius). The same thing is on Alpha Centauri A. Until now, this unusual structure has only been found on the Sun but now the Sun’s twin shares the strange cool layer.
Since time began humanity has built tools and machines to survive and adapt. It started simple with spears and bronze but than became more complex with the invention of cars and planes. We are now at the peak of technological success with inventions such as artificial hearts and all kinds of breakthroughs in medical technology. We can replace almost every human body part, but is that a good thing? I do think it is great that we are able to save people’s live and all, but has the latest upgrade gotten out of hand? Researchers and scientists have created robots made out of programmable living tissue. It is extremely useful and can mend a broken heart, taking away the need for an artificial one. This “Bionic Tissue” is a hybrid material composed of cardiac cells, gel and carbon nanotubes. Muscles made out of this living tissue have the potential to give robots superior strength and other physical properties. And not only that, but its programmable. They can be programmed to swim, move back and forth, and more. This is all incredible but, is it too far? I’m in no way saying robots will rise up and enslave mankind, that’s ridiculous. But I do think we should take these things a bit slower and try to understand them more, it might even prove beneficial.
Researchers from Duke university experimented by allowing two rodents to communicate with each other using brain waves. It first began by placing two rats in separate cages. Each was able to solve puzzles with microelectrodes, a wire 1/100 the width of a human hair, implanted in their brains. The rats were able to solve the puzzle together by sensing the others intentions and actions, even when they couldn’t see each other. The same experiment was than conducted except the rats were thousands of miles apart. One in North Carolina and one in Brazil, the rats were still able to communicate telepathically! This is the first time an animal has directly understood another animal through telepathy.
The weather was great, the rocket looked fine, and everything looked perfect. Perfect… until the launch. Lucky for SpaceX, the issue is in their capability to fix. What happened was, right when the Dragon was about to launch, three of the four thruster pods gave out and the Dragon failed to even start the mission. The resupply mission will still happen, but just a bit later than planned.
SpaceX, a private space flight company, prepares to launch the unmanned Dragon space capsule at at 10:10 a.m. this Friday. The purpose of the mission is simple, resupply the International Space Station orbiting above us. The Dragon will deliver 1,200 pounds of supplies which follows the $1.6 billion contract SpaceX has with NASA stating that SpaceX will provide 12 unmanned cargo deliveries to the Space station. This will mark the third time the Dragon rockets up to the rescue and helps out the NASA.
