Taking my dog out for a whiz can be an experience—without fail, if I'm in a hurry, she is not, and must wander and circle several different areas in search of that precise spot sufficient enough to relieve herself on. And sometimes she'll be in mid-squat and decide, 'Nah, this ain't the place'. I never considered she might actually be tapping into the Earth's magnetic field, whether it's to find a spot to pee, or wander from one place to the next. But maybe she is, according to some interesting new research. As outlined in a new report from the eLife Sciences initiative this is a real possibility. Maybe not the peeing part, but there is evidence to suggest canines have a sort of built-in...

A group of scientists has been working to create a machine able to take the activity in the human brain, feed it into a computer system, and output sentences that are recognizable. The team says that they have trained algorithms to be able to transfer brain patterns into sentences in real-time with a word error rate as low as three percent. According to the team working on the project, earlier efforts in the area were only able to decode fragments of spoken words or a small percentages of words contained in particular phrases. The project was conducted by researchers from the University of California, San Francisco, using a quartet of volunteers who read sentences aloud while electrodes recorded...

Scientists at the University of Bristol and the Technical University of Denmark have made an incredible breakthrough discovery. Researchers for the institutions have achieved quantum teleportation between two computer chips for the first time. They were able to send information from one chip to another, instantly, without the chips being physically or electronically connected. The scientists say that the breakthrough opens the door for quantum computers and the quantum internet. The teleportation is possible thanks to a phenomenon called quantum entanglement, where two particles are so entwined that they can communicate over long distances. With quantum entanglement, changing the properties of...

While the construction of new nuclear powerplants in the United States (and in other countries) seems to be falling out of favor, the same can’t be said for their use by the U.S. Military. The US Navy still relies on nuclear power for the bulk of its large warships. But while those ships are powered by nuclear fission reactors, the Navy is talking up the possibility of using much more promising fusion reactors. The problem is that [safely] harnessing nuclear fusion is incredibly more difficult than nuclear fission, and the currentspace requirements are immense. Nuclear fission occurs when isotopes of uranium or plutonium are bombarded with subatomic particles, splitting them apart...

One of a human baby’s most exciting developmental steps is learning and repeating their first word. However, we still do not fully understand what happens in the brain that helps this learning process takes place. Researchers are now a little closer to understanding speech development, however, and the methods they've employed take a cue from the science fiction movie, Inception. Scientists have actually implanted memories in birds' brains to teach them songs that the birds have previously not heard before. Scientists at the University of Texas Southwestern have been working with cute little zebra finches over the last few years to unlock the mysteries of speech development. Zebra finches...

How long will human beings be the dominant species on the planet? One scientist argues that the reign of humans is coming to an end. Dr. James Lovelock recently contended that humans will be overcome and replaced by cyborgs. Dr. James Lovelock detailed the fall of humanity and the rise of cyborgs in his most recent publication Novacene. Lovelock is not the first person to argue that cyborgs will take over the earth. Elon Musk has contended that human beings will need to embrace artificial intelligence (AI) if they want to survive. He recently unveiled plans for his "Neuralink", which would literally attach wires to a person’s skull. Lovelock’s perspective is rather unique. He defines...

Global warming, nuclear warfare, and a new plague are potential ways that the human race can come to an end, to name just a few. Or an asteroid could barrel into our home planet and leave in its wake mass destruction, causing an extinction event. It's the thing of science fiction, but also real-life. In fact, a rock estimated to be around 187 to 427 feet wide recently zoomed past Earth, and hardly anyone noticed, including scientists. It wouldn't have destroyed humankind, but it could have decimated a really large area. Traveling at nearly 54,000 miles per hour (MPH), the hunk of rock referred to as 'Asteroid 2019 OK' hurled through space and missed Earth by only 45,000 miles. That may seem like...

An amateur astronomer and satellite tracker named Ralph Vandebergh has captured a very rare image of the secret U.S. Air Force X-37B space plane in orbit. The spacecraft is very small and difficult to find in orbit, but Vandebergh says that he had been hunting for the spacecraft in orbit for months before he finally found it in May. He snapped the fuzzy image of the X-37B seen below in June. He used the same trajectory from his initial discovery of the spacecraft to predict where it should be in mid-June when he was ready to snap the images. The catch was that the spacecraft failed to meet the expected time and path because it had shifted to a different orbit. Vandebergh says that a network of...

NASA has had an exciting month; it announced early in June that it intended to open the ISS to private astronauts tours for $35,000 per night. In addition, NASA has now announced that on June 14 a robot called Bumble became the first Astrobee robot to fly under its own power in space. Astrobee robots are free-flying systems meant to help researchers test new tech in zero gravity. Robots like Bumble can also perform routine work along with the astronauts living and working on the ISS. NASA sees a future where robots like Astrobee can be caretakers for the NASA lunar gateway and play a part in NASA's future missions exploring the Moon and Mars. Testing Bumble out on the ISS wasn't as simple...

It's not quite Skynet, but scientists have created "lifelike" machines seem like something straight out of a sci-fi movie. Researchers from Cornell University has crafted what they call artificial machines using synthetic DNA that can move on their own, grow, evolve, consume resources and eventually die. Now before you start putting on your judgmental hats and questioning the ethics of the researchers, they are quick to point out that their creations are not true "living" organisms. "We are introducing a brand-new, lifelike material concept powered by its very own artificial metabolism," writes Dan Luo, who serves as a professor of biological and environmental engineer at Cornell. "We are...

SpaceX has performing admirably in its efforts to move the U.S. one step closer to being able to put its own astronauts into orbit again. The company was able to successfully launch its Crew Dragon capsule early this month, and the capsule later splashed down safely on return from the ISS. SpaceX and its CEO, Elon Musk, have a future that sees SpaceX doing more than putting astronauts into low Earth orbit; and that future includes interplanetary missions. Before those missions can be considered, the spacecraft that will be used has to be built and tested; SpaceX is into that testing process with Musk offering up a video of the critical heat shield tiles in testing. Heat shield tiles are the difference...

Elon Musk and SpaceX have been doing some very cool things over the past decade with rockets. While the rockets SpaceX has been sending into space aren’t the sort capable of flying to the moon or Mars, they are capable of ferrying cargo safely to the ISS in Earth orbit and mostly returning to Earth in one piece. The big news this week was the unveiling of the SpaceX BFR (Big Falcon Rocket) spacecraft that can fly to the moon and beyond. During the unveiling of the rocket, Musk said that the BFR already has its first passenger booked, but during the event, no names were offered. When Musk was asked if he was going to be the first passenger to fly around the moon, he simply tweeted a Japanese...

MIT is poised to make a massive investment into the future of nuclear fusion power. This move is significant because fusion power is potentially inexhaustible and produces zero carbon emissions. Fusion power could quite literally change the world as we know it today. MIT has announced a new collaboration with a private company called Commonwealth Fusion Systems (CFS) that will see $50 million poured into the creation of a working fusion power plant. MIT and CFS want to perform rapid, staged research that will lead to a new generation of fusion experiments and ultimately power plants based on advancement in high-temperature superconductors. The work will be built on decades of federal government...

Researchers from the Massachusetts Institute of Technology (MIT) have announced a new power generating device that is able to use temperature fluctuations to create electricity. The technology is based on principals of thermoelectric devices able to generate power when one side of the device is a different temperature than the other. The device the MIT team has created doesn't require two different temperature inputs at the same time, rather this device harnesses changes in ambient temperature to create electric power as a virtually perpetual renewable energy source. MIT's Thermal Resonator - Virtually Infinite Power Source? The new system is called a thermal resonator and has the potential for...

One of the most memorable scenes in all of science fiction films is the scene in the original Star Wars movie where Luke first sees the holographic projection of Princess Leia while trying to clean R2-D2. Many fans of that film have been waiting for decades for a similar projection system to launch. Physicists have now created a very close approximation to that Star Wars projection using a laser and particle system. The technique is known as a volumetric display and can make 3D moving images that a viewer can see from any angle. "This is doing something that a hologram can never do — giving you an all-round view, a Princess Leia-style display — because it’s not a hologram,"...

A group of Japanese scientists have made an accidental discovery that could have a huge impact on smartphones and other gadgets in the future. The scientists developed a new type of glass that can self-heal, fusing itself back together when it cracks. This could mean the end to shattered smartphone screens and costly repairs. The discovery was made at the University of Tokyo while the scientists were studying new adhesives. Though this isn't the first claim of self-healing materials for phones, this new breakthrough material does seem to have significant merit. One of the scientists on the team noticed while he was studying a polymer for its usefulness as a glue that it had the ability to adhere...

If you spend any amount of time on the Internet, you have certainly run across CAPTCHA on a few occasions. CAPTCHA is the security device that forces you to read squiggly words and type them into the box to prove you are a person and not a spamming robot sent from the future to troll forums and steal all of our memes. The schtick for CAPTCHA is that computer programs can't read the words, but that is no longer true. AI has been created that is able to defeat CAPTCHA security meaning all our memes aren't safe after all. The AI was inspired by a human brain, specifically the human visual cortex. To rub salt in CAPTCHA's wound, the new AI needed 50,000 times fewer training examples to crush the...

CTRL-Labs is a startup that is working diligently in the brain-machine interface, or BMI field. BMI is a type of interface that allows people to control computers using their brain and assistive technology. It could be a huge breakthrough for allowing people with disabilities to make better use of computers, for both work and fun. It's not the first time we've seen functional technology demos in this space. Years back, OCZ actually demonstrated their NIA or Neural Impulse Actuator technology, but it never really took off. However, the BMI that CTRL-Labs is working on is pretty slick according to Wired, which was able to watch a few demos of the technology. In one demo, the user wears sensor-laden...

A team of scientists from the University of Washington have figured out how to infect a computer using malicious code inside DNA. This attack vector isn't aimed at your everyday PC sitting on your desk at home or in the office; this hack aims directly at the infrastructure around the DNA transcription and analysis industry. The team behind the hack was concerned about the security with that infrastructure after finding basic vulnerabilities in some of the open-source software used in labs that analyze DNA all around the world. While the basic issues with the software could be vulnerable to hacks using traditional tools, like malware and viruses, the team of researchers went the extra...
