Most habitable planets may be completely covered in water
When you imagine what a rocky, habitable planet looks like, it's easy to picture an alternate Earth where land and oceans exist in an ideal balance. Unfortunately, that's not necessarily how it will pan out in real life... in fact, you might be surprised if there's land at all. University of Barcelona researcher Fergus Simpson has published a study suggesting that most planets with any significant amount of water are likely to be completely (or almost completely) submerged in it. He ran computer simulations accounting for numerous factors in a planet (such as the deep water cycle and erosion), and most with substantial water levels had an above-water land mass of less than 10 percent -- well below Earth's 29 percent.
Nearby 'super-Earth' may be our best shot yet at finding alien life
Scientists are finding potentially life-bearing planets at a surprisingly high rate, but the latest may be more tantalizing than most. A research team has discovered LHS 1140b, a temperate rocky exoplanet orbiting the habitable zone of a tiny star 40 light years away. While it's not the first such planet found relatively nearby, it's an ideal candidate for study -- since it transits in front of its host, astronomers could look for water and oxygen in the planet's atmosphere by watching how it filters starlight. The star itself also doesn't emit much high-energy radiation, so there's a greater chance of life than you might see around stars like TRAPPIST-1.
Facebook details its plans for a brain-computer interface
Facebook wants you to use your brain to interact with your computer. Specifically, instead of using something primitive like a screen or a controller, the company is looking into ways that you and I can interact with our PCs or phones just by using our mind. Regina Dugan, the head of Building 8, the company's secretive hardware R&D division, delved into this on stage at F8. "What if you could type directly from your brain?" she asks.
Alphabet starts collecting health info to better predict disease
It didn't take long for Alphabet's Verily to get its watch-based health study off the ground. The life sciences company has launched its 4-year research initiative, Baseline, to potentially spot early signs of diseases before obvious symptoms appear. Verily's health-tracking Study Watch plays a central role, of course, as it will track everything from heart rate to ECGs to the skin's electrical conductivity. However, that's just one piece of the puzzle -- the team will look at numerous other factors to see where disease begins.
Remembering the first 'photo' of a black hole
Black holes are so outlandish that the scientists who first thought them up figured they couldn't possibly exist in reality. They form from massive, collapsed stars and are so dense that nothing can escape their gravitational pull, including light. Black holes mess with spacetime so badly that scientists have long wondered: How do these things look, exactly? We may be on the cusp of seeing one thanks to the Event Horizon Telescope, but back in 1979, Jean-Pierre Luminet created the first "image" using nothing but an early computer, lots of math and India ink.
The Morning After: Wednesday, April 19th 2017
Hey, good morning! This morning, we put Samsung's Galaxy S8 through its paces, finally seeing why Facebook bought VR company Oculus, and started replaying a 20-year-old game. (Because it's free.) Welcome to the Morning After.
The Morning After: Tuesday, April 18th 2017
Hey, good morning! We're warming up for F8. Yep, Facebook's big annual event kicks off today and it looks like the company has an awful lot planned to show us. Meanwhile, Netflix has explained why it continues to pay for Adam Sandler's creative output and Verizon made its own smartwatch for some reason. Oh, and here's a DIY distillery.
Watch NASA's first 360-degree live stream of a rocket launch
Rocket launch videos are typically captured from afar, putting you in the shoes of a spectator in the crowd. NASA's live coverage of an Orbital Cygnus spacecraft's ISS resupply mission, however, will take you to the launch pad itself. For the first time ever, the agency will broadcast a live 360-degree video of a rocket launch on the NASATelevision YouTube channel tomorrow, April 18th.
Theranos settlement means it could have a lab again in 2019
Theranos has been headed toward disaster for a while through its questonable blood testing methods, but it might have just avoided the worst possible outcome. The biotech outfit has reached a settlement with the Centers for Medicare & Medicaid Services that should end the legal and regulatory fights between the two. In return for Theranos dropping appeals of both its 2-year lab ban and sanctions on its Newark lab, CMS has decided against revoking Theranos' Clinical Laboratory Improvement Amendments (CLIA) certificates and reducing the civil financial penalty to $30,000. Theranos is voluntarily giving up the certificates, as it's not running labs that would need them.
NASA seeks comet 'crumbs' with a new detection technique
It's relatively trivial to spot comets, but spotting the dust they leave behind? That's no mean feat -- it's like tracking grains of fast-moving sand on a cosmic-scale beach. NASA, however, might just have a way of mapping that dust. It's developing a technique that would use the movement of the ESA's LISA Pathfinder probe to detect the minuscule "crumbs" left by comets and asteroids. The trick involves tracking the tiny thruster bursts Pathfinder uses to compensate for dust stream impacts. When you measure the direction and strength of those bursts, you can get a good sense of the dust's impact location, size and trajectory.
Most of us are using our phones while driving
Between the hefty fines, disturbing PSAs and social shunning that comes from using your phone while driving, it turns nearly everyone is still texting, tweeting and generally fiddling with their phones while behind the wheel. According to Zendrive's extensive three month study of three million US drivers, we're use our phones at least once during 88 percent of our trips.
Researchers simulate walls in VR by shocking your muscles
Virtual reality is still a pretty crappy facsimile of The Matrix, but scientists are trying their best to fix that. At the CHI'17 conference in Denver, a team of researchers from the Hasso-Plattner-Institut in Potsdam showed off a haptic system that can simulate walls or heavy objects via electrical muscle stimulation. "We were really interested in trying to explore one of the hardest things to recreate in terms of physical sensation, which is a wall," says co-author Pedro Lopes.

Hey, good morning! While we consumed our body weight in chocolate, the US Navy banned vaping on its entire fleet and EA detailed the sequel to Battlefront. There's also a drone that can spy on fish, some stealth iPad upgrades and a potentially life-saving AI.
Toddlers who use touchscreens sleep less, study says
Toddlers really need their sleep. It's crucial when our brains are first developing, so early problems can ripple across your lifetime. That makes a report by Birbeck University of London researchers somewhat disturbing -- they found that toddlers between six and 11 months who play with smartphones or tablets get slightly less sleep than those who don't. According to the study of 715 parents, every hour of touchscreen use results in 15.6 minutes less sleep, or 26.4 minutes less total per night and 10.8 minutes more during the day, on average.
Smart bandages will use 5G data to track your health
Bandages are usually very mysterious -- it's hard to know how well you're healing until you unwrap them, and that usually means a trip to the doctor. If Welsh researchers succeed, however, you'll never have to wonder what's going on underneath all that cloth. Swansea University is planning trials (due within 12 months) of smart, 3D-printed bandages that will use 5G wireless data and nano-sized sensors to constantly relay details about your health. It would help physicians customize treatment based on the progress of your wound, your location and your activity. If you're healing well and are staying active, for example, you may get a different solution than someone who's recovering slowly and needs to stay home.
Computer models help form new magnetic materials
Magnetic materials are extremely difficult to find. They're rare in nature, and creating one in the lab usually involves both a lot of experimentation and a little luck. Duke University, however, has found a way to take the mystery out of the process: its researchers have used computer modelling to help generate two new kinds of magnetic materials. The models whittled down the potential atomic structures from a whopping 236,115 combinations to just 14 candidates by subjecting the structures to increasingly tougher tests. How stable are they? Do they have a "magnetic moment" that determines the strength of their reaction to an outside magnetic field? After that, it was just a matter of synthesizing the few remaining materials to see how well they worked in real life.
AI can predict heart attacks more accurately than doctors
An estimated 20 million people die each year due to cardiovascular disease. Luckily, a team of researchers from the University of Nottingham in the UK have developed a machine-learning algorithm that can predict your likelihood of having a heart attack or stroke as well as any doctor.
Watch the ESA trace 2 million stars' journey across the skies
Carl Sagan showed how some constellations would change over time as stars move through the universe in his TV series Cosmos. Now the European Space Agency has done something similar, but in a much bigger scale: it has released a video showing 2 million stars' journey across the skies from today until 5 million years into the future. The ESA used data provided by the the Gaia satellite and its one-billion-pixel camera, as well as data from the Hipparcos satellite that measured the positions of celestial objects back in the 1990s.

Hey, good morning! You look fabulous. Welcome to the weekend! We have news on the Microsoft Windows zero-days that weren't, and a teaser trailer for the next Star Wars movie.
Komodo Dragons may hold the key to fighting infections
Komodo Dragon blood could save your life. Curious scientists -- are there any other kind? -- recently identified a peptide in the Dragon plasma that might serve as an antibiotic. Now, a bite from a Komodo Dragon is lethal not from venom, but from bacteria in the reptile's saliva, and the Dragons don't kill each other when they get into tussles the way they do hunting prey, which suggests an immunity. So the researchers, inspired by previous work done with alligators and crocodiles, made a synthetic version of a peptide (a chain of amino acids) found in Dragon's plasma, VK25.
