The “S” at the end of HTTPS stands for “secure”, and it first saw major use as a way to make sure transactions online were secure. It works through a pretty basic encryption protocol. To access a secure site, the browser requests a public key. Using that key, it encrypts all messages sent to that site, which can decrypt them using its private key. Once the connection is set up, all messages sent over it are secure from eavesdropping....
In a medical system where people with higher weights experience discrimination on a regular basis, getting the vaccine early was a rare and welcome perk. But experts in weight stigma say that there are problems associated with labeling obesity as a risk factor for COVID-19. Not only is it impossible to conclude that high BMI directly causes worse COVID-19 outcomes—to do so is actively harmful to the health of people living in bigger bodies....
Pogo is, properly speaking, a thrust axis vibration response seen in liquid fueled rockets that can have devastating effects on the vehicle’s whole structure and, by extension, a crew on board. Think of a rocket upright on a launch pad. For that rocket to get off the ground, propellant and oxidizer have to flow down into the combustion chamber at a high enough pressure to burn with enough power to propel the whole stack off the ground....
Unfortunately, we can’t simply look at all the stars with telescopes and count them up. That’s because our galaxy isn’t only full of stars. There are also clouds of dust and gas that block our view of dim or faraway stars. So astronomers have to answer this question by working backwards. The first step is to figure out how much stuff, or mass, there is in the entire galaxy. Astronomers at the University of Arizona recently estimated that the Milky Way weighs about 960 billion times as much as our own sun....
At the edge of the Cliffs, as they’re called, just past the bowling alley and as Main Street yields to rural openness, there’s something unusual for such a small community: a public observatory, designed to look like a weathered mining structure, with a substantial telescope inside. On a cold-but-not-as-cold-as-it-could-be evening, Clint Smith—Custer County attorney and president of the advocacy group Dark Skies of the Wet Mountain Valley—stands inside readying the scope....
Using a computer model, researchers examined what might happen if the amount of carbon dioxide in Earth’s atmosphere increased dramatically. Really, really dramatically. In a paper published today in Nature Communications, NOAA researcher Max Popp took a look at what would happen to a watery planet like Earth if carbon dioxide levels in the atmosphere just kept going up. Right now, the amount of carbon dioxide in our environment is hovering at 400 parts per million a number that is already large enough to start affecting our environment....
Researchers from U.S. Department of Energy’s Lawrence Berkeley National Laboratory, publishing online in the most recent issue of the journal Science, placed human, chimpanzee and macaque versions of the enhancer into mouse DNA. The scientists also added a gene that would release a blue dye to show where in the mouse fetus the enhancer was most active. When the mice developed, the researcher saw that it was active in the hands, feet and throat....
Your phone’s messaging app can be a sneaky storage hog. Whether you’re using Messages on iOS or Google Messages on Android, your settings could be taking up chunks of your device’s memory. Changing them to delete message attachments is a quick way to free up space on your phone. How to delete message attachments on iOS Don’t be surprised if your Messages app is the second-largest on your phone—any pictures you send or proactively save are hanging out in both your photo library and Apple’s built-in messaging app....
OK, we may have been a little over-dramatic off the bat—we’re talking about browser tabs here, not a profound philosophical revelation. But if you’re someone who always has a lot of tabs open in Chrome and at least tries to keep them organized, it may be at least minimally life-changing to know you can drag and drop links to open them anywhere among your existing tabs could change how you use the web....
For years, phones and laptops have come with built-in tracking options, so you can use your Google, Apple, or Microsoft account to quickly locate a device before leaving home. And for gadgets with no integrated GPS, such as your digital camera or Nintendo Switch, Bluetooth tags can alert you before you walk out the door without them. Whether it’s that or the fact you forgot to pack your digital camera for your latest vacation (something your partner surely won’t let you forget), know that we’ve all been victims of our fast-paced lives....
The Biden administration plans to ship 10 million vaccine doses to multiple states who preordered the vaccines with millions more to come in the coming weeks. Deliveries will first go to top-priority sites like pediatric hospitals where there are many high-risk kids. Every state except for Florida has ordered vaccine doses in preparation for the approval, meaning almost the entire country will have vaccines available as early as June 21....
Our children’s pickiness is in part a natural phase of their development. They’ll most likely grow out of it, but we still need your guidance establishing a healthy and flexible relationship with food. Being able to try unfamiliar flavors and textures will help them be comfortable in any culinary environment, and discover new favorite dishes. This will also teach them to value food beyond taste, and appreciate it for the nutrients it provides and how good they are for us....
Most ice you make at home or purchase from a store is at least a bit cloudy. While this cloudiness is often attributed to vague “impurities,” the cleanliness of your starting water has little to do with it. Of course, you should always start with clean water, but even an ice tray full of filtered, boiled water will still produce cubes with cloudy centers. Within those outer layers of your half-frozen cubes, there will be a bubble of air just waiting to cloud up your ice....
But noseriding works precisely because of physics. Only a confounding force would permit a surfer to place a couple hundred pounds on the end of a plank and appear weightless, sometimes with hardly any water on the tail. Learning how the forces work will give you a leg-up in noseriding or provide you with an appreciation for the aesthetics of Newtonian law while watching the surfers from the beach....
When the German magazine Stern approached Donald Miralle to shoot a new line of Harley-Davidson motorcycles, the Carlsbad, California-based commercial and editorial photographer was thrilled. Then it hit him: “I’d had very little experience shooting moving vehicles!” It helped, though, that Miralle had a particular image in mind-the one shown here. “My aim was to find an angle on this subject that no one had yet documented,” he says. “While I may not have entirely succeeded, I feel I did place my own perspective and spin on it....
While convenient, there’s a lot that could go wrong. A public relations team member, for example, could have unknowingly transferred malware to the device when uploading its content. Or, perhaps a more unscrupulous employee or contractor actively sought to turn the drive into a spy device—a Trojan horse of sorts—that carries tiny bits of executable code. Once inserted into one of your PC’s ports, it could automatically download an app, prompt you to download one, or run malware that could steal or destroy data on your computer....
Now, the stakes—literally—are not as high today as they were when Wallace’s infantry raised sharpened wooden poles at the last moment, obliterating the rushing horsemen. But those three words will truly help you as I walk through how to select and move multiple apps at once on your iPhone’s home screen. Now, using any finger other than the one keeping pressure on that first app you touched, start tapping the icons you want to move....
At their best, email newsletters are distracting digests of news or insights you can catch up on while drinking coffee or commuting to work. But most newsletters are the ones you signed up for to get 15 percent off of a sweater. Now you get an email from that retailer every other day. They’re compounding your email overload without bringing anything useful or valuable to the table. If you find you’ve signed up for many, many email newsletters too many, don’t just accept your fate—unsubscribe from the ones you no longer want or need....
Although merely a cosmetic change to a phone that was already stocked with excellent computing hardware and pleasing physical design (with a 1440p screen measuring 5.7 inches diagonally, 1.9 GHz Snapdragon processor and 3GB of RAM, and a fingerprint sensor distinctively placed on the center back), the Matte Gold color makes Huawei’s 6P more directly comparable to Apple’s iPhone 6 and 6S (both available in gold), and could perhaps appeal more to a global audience....
“Our findings…suggest that these birds really are experiencing a whole range of colors we humans can only imagine,” says Mary Caswell Stoddard, an ornithologist at Princeton University and coauthor of the new study. “We humans are really limited in how we understand and appreciate and can describe the color experience of birds and other animals.” The average human eye can distinguish around one million different colors. Our color vision depends on three types of cones—special cells sensitive to red, blue, or green light....
