The red planet’s gravitational pull is a little over one-third of Earth’s, which is far from ideal for making sure people can live, work, and thrive. As we know from long-duration missions in orbit, microgravity and partial gravity environments can wreak havoc on the body, especially when it comes to sustaining bone and muscle mass. Research has shown that astronauts can lose up to 20 percent of their muscle mass on missions that last just five to 11 days....

A study published January 5 in the journal Nature Ecology and Evolution looked at five black rat-infested and five rat-free islands in the archipelago. The rats appear to have changed the territorial behavior in some of the fish on the surrounding coral reefs. One of these is the jewel damselfish (Plectroglyphidodon lacrymatus), an herbivorous species of tropical reef fish that tends to and “farms” algae in the branches of corals....

YouTube got in the game a few years ago, offering a facial blurring tool to help protect protestors against retribution from law enforcement or employers. But machine learning researchers at Cornell Tech and the University of Texas at Austin have developed software that makes it possible for users to recognize a person’s concealed face in photographs or videos. The researchers used this software to defeat three different privacy tools, Wired reports, including both blurring and pixelating technologies....

The Samsung Galaxy S7 is the 2016 update to the company’s flagship smartphone product. While many handset manufacturers create Android devices, Samsung’s products are lauded as the iPhone’s biggest hardware competitor. Today, for the first time in a year, the flagship Galaxy S lineup saw an update. The Event In VR Most noticeable about Samsung’s Galaxy S7 press conference at MWC in Barcelona were the Gear VR headsets attached to each seat....

It may seem foolish to invest in physical media during the golden age of streaming, but Criterion has distinguished itself by treating the films it chooses to release with the utmost care. The company does its own director-approved film transfers and goes the extra mile to supplement its releases with bountiful extras, from special features and multiple commentary tracks to thick booklets full of essays, recollections, and other ephemera. This deluxe treatment typically comes at a premium—$30 for a DVD, $40 for a Blu-ray, and $50 for a 4K Blu-ray, to be exact—which is why Barnes & Noble’s sale is such a great deal....

That’s what we know. But despite the fact that humans have been studying the pyramids for centuries, these giant structures still have some secrets that we haven’t uncovered yet. Earlier this week, Egypt’s antiquities ministry announced that researchers have noticed strange thermal readings during scans of the largest of the Giza pyramids. After scanning the pyramids with instruments designed to take the temperature of the structures’ stones, researchers noticed three stones near the base of the pyramid that were slightly warmer than the surrounding facade....

Over the past five years, the researchers have collected genetic data from 65,000 people in 30 countries. They knew that mutations in certain genes were linked to schizophrenia, but the researchers wanted to use their huge dataset to find the strongest correlation possible. And they found one—people with highly expressed variations of a gene called complement component 4 (C4) were much more likely to develop schizophrenia. They confirmed the connection between C4 genes and protein production by analyzing 700 samples of human brains....

Now, eyes are not known for being tough: You can scratch them, jab them, they’re soft little orbs. And notably, they’re made of organic materials. Not so for the Acanthopleura granulata. This species of chiton has hundreds of tiny eyes dotting the plates that protect it, and the lenses are made of inorganic material. Where eyes are typically made out of protein, chiton eyes are made of a transparent aragonite, which is the same hard, ceramic material that its tough shell is made out of....

“This is the first time that you can really go through and get a very personal view of climate evolution at a spot that’s meaningful to you,” says Matthew Osman, a climatologist at the University of Arizona, and the study’s lead author. “I hope what this does is help ingrain a sense of just how severe climate change is today.” The map is built by comparing sediment cores, which contain a record of temperatures over thousands of years, with historical climate models....

What is the Sennheiser IE 300? The Sennheiser IE 300 is a mid-tier high-fidelity earphone from a company with a well-deserved reputation for designing high-quality microphones, speakers (such as the AMBEO soundbar), and headphones for both mixing and merely enjoying. The German company’s gear can be found on stages, in studios, and in the homes and backpacks of audiophiles. Sennheiser took cues from live-performance in-ear monitoring systems while designing the IE 300 so, like the Sennheiser IE 100 Pros, the earphones are light, unobtrusive, and comfortable to wear whether running from place to place or sitting at work, in transit, etc....

Chief Technology Officer at IMAX, Brian Bonnick says the exact IMAX process of engineering a movie for the really big screen is proprietary but requires filmmakers to start thinking about the presentation before they even begin shooting. For the Russo Brothers directing team, their IMAX experience started out tentatively. They used a joint customized digital version of ARRI’s then-new large format camera, the Alexa 65, to shoot the airport superhero showdown at the center of Captain America: Civil War in 2016....

Enemy fire in the area will make a supply recovery mission risky, however. An Army convoy must risk IEDs and sniper fire to retrieve the goods. If only the pallet would only drop more precisely, much closer to the base”s boundaries, the soldiers could stay out of harm’s way. To do this, the pallet must sail through treacherous, parachute-ripping rock outcroppings, landing in a patch of earth that a convoy can quickly and easily reach....

A new platform billing itself as “next-generation citizen science” is promising to make it easy for anyone who wants to collect or share environmental data. Called Anecdata, the first version of the software was developed at MDI Biological Laboratory’s Community Environmental Health Lab, and used to document eelgrass decline in Maine. Using the site is free, but the organization behind the software offer a number of paid services, such as custom site development, maintenance and hosting, supported development, and citizen science consultation....

In the study, the researchers stressed out several mice by periodically putting a much more aggressive mouse into their cage. After six days of exposure, the stressed mice could no longer recall the location of a hole to escape a maze, which they remembered easily before the stressful period began. “The stressed mice didn’t recall it. The mice that weren’t stressed, they really remembered it,” said Jonathan Godbout, a neuroscience professor at Ohio State University and one of the study authors in a press release....

The loud noises, bright flashes, and pungent scent of gunpowder that accompany fireworks can be a trigger for people who have served in the military, are refugees of war, participated in protests, or survived a natural disaster, to name a few of the groups who may struggle this weekend. For some, these aerial explosions can trigger a full-body response, ranging from heightened anxiety to complete dissociation and hallucinations. This doesn’t mean that somebody with PTSD cannot or will not be able to enjoy life during firework season....

Knowing that the infamously rugged creatures could survive punishing temperatures and even the vacuum of space, Arch Mission Foundation co-founder and chairman Nova Spivack couldn’t help but wonder how the microscopic creatures had fared. Had he incidentally seeded the moon with life? Researchers say while the lunar environment is largely inhospitable even to tardigrades, some might indeed have survived the crash—but that doesn’t mean the moon is home to life as we know it....

Well, in case the message was still unclear to you: It. Is. Not. Aliens, according to the conclusions of a new review study published in Nature Astronomy. And given everything else about ‘Oumuamua that we’ve learned in the past year-and-a-half since its discovery, that’s a very safe bet to get behind. “In every way we look at this object, it looks like a planetesimal—a building block of a planet,” says Michele Bannister, a planetary astronomer from Queen’s University Belfast and the lead author of the new paper....

Ram Revolution electric truck concept The biggest automotive moment from the show may well have been the splashy reveal of the much-anticipated Ram Revolution, an all-electric pickup truck. Ford is already selling its Lightning EV and Chevrolet’s Silverado EV will go on sale this spring, so while it may seem that Ram is catching up, it appears that it may be right on time in the grand scheme of things. President and chief analyst at AutoPacific Ed Kim says the importance of the Ram Revolution, the truckmaker’s first EV, can’t be overstated for the North American market....
