Four lasers beam out from one of the Unit Telescopes of ESO’s Very Large Telescope (VLT), guiding your eyes to the Small and Large Magellanic Clouds beneath them.
The Four Laser Guide Star Facility (4LGSF) shines four 22-watt laser beams into the sky to create artificial guide stars by making sodium atoms in the upper atmosphere glow so that they look just like real stars. The artificial stars allow the adaptive optics systems to compensate for the blurring caused by the Earth’s atmosphere and so that the telescope can create sharp images.
What do you get when you mix science fiction with music and some of the most powerful and important social issues to date? You get Janelle Monáe’s highly anticipated short film (or as Monáe astutely calls it ‘Emotion Picture’) Dirty Computer, which accompanied her new album by the same name.
A futuristic celebration of queer love, black and female power, and the nonconforming individual identity!
It seems popular cryptocurrency wallet MyEtherWallet is having issues. A litany of concerned users are reporting their wallets have suddenly been drained out – without any notification or action on their side.
The unexpected withdrawals have caused many netizens to suspect that MyEtherWallet has been hacked. Despite speculation though, the issue might have to do with with a glitch in Google’s Domain Name System (DNS) protocol.
Speaking to Hard Fork, MyEtherWallets reps clarified that the popular app “is not hacked.” Instead, the company claims that the unusual activity “was a DNS attack on Google DNS servers.”
Google’s co-founder Sergey Brin has written about the threat and promise of artificial intelligence in his annual letter to shareholders. The Alphabet president says AI has brought about a ‘technology renaissance’ but says problems raised by this tech demand ‘serious thought and research.’
Whole genome sequencing is more precise than other methods, and it just keeps getting faster and cheaper. Joel Sevinsky, head of the Molecular Science Laboratory at the Colorado Department of Public Health and Environment (CDPHE), told the Associated Press his lab can sequence the genome of a suspected pathogen in less than 72 hours.
Whole genome sequencing is already helping researchers address food-borne outbreaks, including a 2017 salmonella outbreak that stretched across 21 states, and the current romaine outbreak.
It’s even identifying contaminated food before it even reaches the public. According to the AP, inspectors used genome sequencing to find pathogens that could have caused outbreaks when they inspected food plants. They were able to recall the tainted products before they ever reached grocery stores or restaurants, preventing countless people from being sickened.
I have noticed that people are commenting on my article after looking at the picture and not even watching the videos or reading it. This is related to the point I’m making in this article about programming.
When the top executives, that helped create Facebook and make it popular, are warning people against the destructive and negative side of it and social media, we should be listening. Find out what they said and what really going on and why…
Apparently needs a lot of work before it can actually operate like a eel/snake. But, i’d wrap this up in skin so it could look like a snake/eel. Give it solar power skin so it could recharge its own batteries; maybe try to use that system that was supposed to be able to eat organic matter to convert into power. Then, put a bunch of sensors on it, and HD cameras for eyes, and rig it so it could transmit to satellites. And you have a pretty impressive drone that can operate in any body of water and on land close to water.
An innovative, eel-like robot developed by engineers and marine biologists at the University of California can swim silently in salt water without an electric motor. Instead, the robot uses artificial muscles filled with water to propel itself. The foot-long robot, which is connected to an electronics board that remains on the surface, is also virtually transparent.
The team, which includes researchers from UC San Diego and UC Berkeley, details their work in the April 25 issue of Science Robotics. Researchers say the bot is an important step toward a future when soft robots can swim in the ocean alongside fish and invertebrates without disturbing or harming them. Today, most underwater vehicles designed to observe marine life are rigid and submarine-like and powered by electric motors with noisy propellers.
