New tabs in apps allow for more work in the same amount of space Apple went into developer mode with its own apps and souped them up for you. Now, you can use multiple tabs in apps like Maps, Keynote, Numbers, and others. The screenshot below is what your Maps app looks when you first open it. Press “Command” and your “t” key to open a new tab, or go up to “File” on the top menu bar, click it, and press the “New Tab” option in the dropdown menu....

So we thought everyone could use a few pointers about how they can work off the excess calories. Before we proceed, however, one caveat: if you are planning to eat the traditional Christmas dinner outlined below, keep in mind that the portions in this graphic are based on “serving sizes,” which are based on how much food people were eating, on average, 30 or 40 years ago, which–holiday splurging aside–was way less than people are eating now....

The evening of Feb 24, outlying military sites of Mariupol, a Ukrainian city on the northern coast of the Sea of Azov, came under Russian assault. That assault has intensified in the days and weeks since, as Russian forces advancing from Crimea in the southwest and occupied Donetsk in the east encircle the city, making its capture or destruction a crucial objective of the weeks-old invasion. The scenes out of Mariupol are haunting....

A new study from Smart Growth America, an urban development-focused nonprofit, found that the number of pedestrian fatalities spiked more than 60 percent in the last decade. In 2020 alone, more than 6,500 people were struck and killed by vehicles—a record high that equates to nearly 18 people dying every day. And despite fewer cars on the road during the COVID-19 pandemic, the number of pedestrian deaths might have been even higher in 2021, according to the Governors Highway Safety Association....

According to the European Space Agency (ESA), the reddish blooms that spread throughout M74 are large clouds of hydrogen gas. The ultraviolet radiation from hot, young stars embedded within the hydrogen clouds make them glow. Astronomers call these regions H II regions and they mark the spot of recent star formation. H II regions are an important target for space telescopes like Hubble and ground-based telescopes because they help astronomers determine a galaxy’s distance and chemical composition....

The term ‘geometry’ derives from Ancient Greek and literally means “earth measurement.” In the classical world, it was used heavily for centuries by the Mesopotamians, Egyptians, and Greeks for just such purposes, long before the tablets in question were created (ca. 400 – 50 BCE). But where these peoples were using geometry to measure lengths, areas, and volumes of objects in a physical space—i.e. on Earth, with objects you can see and touch—whoever scratched geometrical calculations of Jupiter’s trajectory into clay tablets was measuring time and velocity in an abstract space; things you cannot see or touch, but must conceptualize....

Conventional computer chips, whether in your phone or a supercomputer, hold transistors that process information as binary code: Everything is either a 0 or a 1. Quantum computers use qubits ( “cue-bits”), which can be both a 0 and a 1. The machines they inhabit can crack problems faster. But there’s a rub: Qubits are fragile. Any interference can muddy computations. Yale University applied ­physicists Robert Schoelkopf and Michel Devoret ­pioneered a way to stabilize them....

Here are our favorite leisurely, light-weight indoor hammocks. The Brazillian-style Vivere double hammock is available in nearly 40 stunning colors and striped patterns, and four fabrics—cotton, polyester, sunbrella, and mesh. It comes with a nine foot heavy duty steel stand that assembles in minutes without any tools and fits into a premium canvas carry bag for easy storage. These hammocks have pure polyester end strings that last longer than traditional cotton end strings, a bed length of 87 inches, and adjustable hooks that allow you to decide how low or high you want to lay....

Aboard the International Space Station (ISS) right now is a metal box, the size of a desktop PC tower. Inside, a nozzle is helping build little test parts that aren’t possible to make on Earth. If engineers tried to make these structures on Earth, they’d fail under Earth’s gravity. “These are going to be our first results for a really novel process in microgravity,” says Ariel Ekblaw, a space architect who founded MIT’s Space Exploration Initiative and one of the researchers (on Earth) behind the project....

Yes, 2015 was the hottest year on record, according to reports issued by NOAA and NASA today. It’s the hottest year since records started being kept in 1880. 2015 takes the lead in a strong field of contenders. 15 of the 16 hottest years on record have happened since 2001, but really there was no contest. 2015 smashed the previous record set by 2014 by a whopping by 0.23 degrees Fahrenheit (0....

With its new Breeze LT boots, Vasque shaved weight off a part of the footwear that you probably don’t think about too much: its outsole. Those outsoles—the part of the shoe or boot that touches the ground below—are made by Vibram, and called Litebase. What Patagonia fleece vests are to corporate types, Vibram is to the soles of outdoor shoes. To make this ultra-thin sole, the company needed to find a way to make the outsole skinny, light, but strong....

You should know that any photo you take is, theoretically, protected by copyright. That means there are some things you can do to both prevent someone from stealing your work, and enforce this protection in case theft happens to you. Copyright 101 Copyright arises automatically whenever you make an original creative work (by taking a photo, for example). But, at least in the U.S., copyright is “essentially toothless” if you don’t also register the work with the U....

“This is a significant increase, paving the way for new discoveries,” said Mike Lamont, director for Accelerators and Technology at the European Organization for Nuclear Research (CERN), in a press release. One goal of the new LHC era is to better understand the structure of the Higgs boson, a subatomic particle the collider uncovered a decade ago. The Higgs boson particle, which scientists theorize gives other particles such as electrons and quarks their mass, was created 10 to 12 seconds after the big bang that created the universe billions of years ago....

Here’s a recap you can read at your desk while making a stressed-out face so it looks like you’re working when you’re actually just trying to run out the clock until the weekend. Have you listened to the latest episode of Techathlon? On this week’s episode of the most-fun tech podcast around, we talk about ridiculous marketing schemes, our digital hoarding shame, and we eat fruit roll-ups made of ketchup....

How is lead introduced to the body? Humans have long known that lead can cause detrimental health effects—some claim it contributed to the fall of the Roman Empire. But the substance’s effects were first documented in children about a century ago, says Jay Schneider, a neuroscientist at Thomas Jefferson University. However, lead was still common in many household products—especially paint, in which it was used to add color and stability the mixture, until it was banned in 1978....

The pilot tosses the cylindrical Sentry drone into the air and then takes control. Video from the drone’s HD camera is fed live to screens for a second person to watch. The drone can optionally carry an infrared camera, which is good for finding warm bodies hidden amidst cold nature. The drone folds up into a compact cylinder, thought not in a way as aesthetically pleasing as some other foldaway quadcopter designs....

The parasite appears to have been present in the U.S. for a long time. However, aside from a single case found in a deer in Texas in 1957, it has remained virtually undetected until now. Given this timeframe, researchers believe that other mammals in the United States could also be infected, although they haven’t yet identified any. However, it seems this parasite cannot infect or cause disease in humans. There are more than 100 different species of malaria parasites, and only four of those consistently cause infection in humans, according to the CDC....

As the third biggest cocoa powerhouse in the world, Indonesia’s farmers have a lot to lose as climate change threatens the $80-million export industry. As rainfall patterns shift and temperatures climb, land ripe for cocoa cultivation will fall by 9 percent by 2050. Deforestation across the country is also making the fruit trees more susceptible to pest infestation. But while climate adaptation measures are being put in place to protect smallholder farmers (those who harvest on under five acres of land), not everyone is convinced that these measures are working....

My dad has an enormous backyard in suburbia—he likes to throw barbeques and pool parties, and to show off his grilling skills. At every single party, he’ll slyly ask if anyone has been bitten by a mosquito, to which every single guest will reply no. His secret: garlic concentrate, which he sprays around the backyard every few weeks. It works surprisingly well. DEET has a bad rap, but it’s safe, especially if the alternative is risking Lyme disease, malaria, Zika, or West Nile virus....
