Underwater cloaking devices closer than ever thanks to new breakthrough

Underwater cloaking devices closer than ever thanks to new breakthrough

Scientists have developed a cloaking device that cloak submarines operating under the ocean surface called an underwater acoustic ground cloak. Scientists on the project from Pennsylvania State University have described the physics behind the cloaking device. The team set out to design a metamaterial that allows sound waves to bend around an object as if it's not there.

Third-hand cigarette smoke is a big problem in non-smoking rooms: study

Third-hand cigarette smoke is a big problem in non-smoking rooms: study

Most people know about second-hand smoke -- the cigarette smoke you inhale when in close proximity to someone who is smoking. Less known is "third-hand" smoke, which is the residue that persists on smokers' clothes and other things after they've finished smoking. This third-hand smoke may have a bigger impact on health than thought, with researchers finding that it makes its way into non-smoking environments.

World’s first robot-assisted spinal surgery performed

World’s first robot-assisted spinal surgery performed

Surgeons at the University of Pennsylvania School of Medicine have completed the world's first robot-assisted spinal surgery. The procedure was a long and arduous one to remove a tumor from the neck of a 27-year-old man through his mouth. The procedure took over 20 hours in the operating room over two days.

Exoplanet without clouds is the first of its kind ever discovered

Exoplanet without clouds is the first of its kind ever discovered

Researchers have revealed that an exoplanet called WASP-96b, which is described as a "hot Saturn," doesn't have any clouds. This is a first for known exoplanets, according to the team led by University of Exeter's Dr. Nikolay Nikolov. The discovery was made in part using the Very Large Telescope located in Chile. With it, researchers studied the planet as it passed in front of its star.

Avoid these sunscreens (they kill coral)

Avoid these sunscreens (they kill coral)

Two types of sunscreen were banned from sale in Hawaii in a State Senate action this week. Those sunscreens and sunblocks (whatever you'd like to call them) with oxybenzone and octinoxate were banned after enactment by the legislature of the state of Hawaii. According to the bill for the act, these chemicals kill coral - and you know what happens when all the coral dies, right?

Utah tourists keep throwing dinosaur footprints into a lake

Utah tourists keep throwing dinosaur footprints into a lake

Utah's Red Fleet State Park near Salt Lake City has a big problem: visitors keep accidentally destroying precious dinosaur tracks. The tracks are imprinted in sandstone, which visitors keep prying up to chuck into a nearby reservoir. At least ten notable prints have disappeared in only six months due to visitors' actions, many of which may be gone forever.

Video game maps made by AI: More DOOM!

Video game maps made by AI: More DOOM!

This week three researchers might've changed the course of history in the video game industry. They've used a pair of Generative Adversarial Networks (GANs) to study DOOM levels - DOOM, the original DOOM, the first-person shooter. With artificial intelligence, these researchers went about creating new DOOM levels without the assistance of humans.

“Snowball Earth” may have been caused by the start of plate tectonics

“Snowball Earth” may have been caused by the start of plate tectonics

Science says that about 700 million years ago the Earth was covered from pole to pole in a massive amount of ice and snow. This period is called "Snowball Earth" by scientists and a wealth of theories have surfaced over the years to explain what might have caused this to happen. The latest theory suggests that the root cause of Snowball Earth could have been a cracking crust at the beginning of plate tectonics.

NASA nuclear power system test in Nevada desert was a success

NASA nuclear power system test in Nevada desert was a success

In January, it was announced that NASA had teamed up with the US Department of Energy to test a nuclear power system called the Kilopower project. The test was set to be conducted in the Nevada desert, where researchers would fire up the system after having previously tested its individual components. That brings us to last month when officials from both agencies started the process.

Long-term moon dust exposure may have severe impact on human health

Long-term moon dust exposure may have severe impact on human health

Researchers with Stony Brook University have published a study with concerning implications for future manned lunar missions. Using simulated lunar soil, the team found that moon dust may be toxic to humans, particularly to lungs. As well, the research shows a toxic effect on mouse neurons, indicating other possible health ramifications that await humans traveling to the lunar surface.
