In 2006, Pluto was reclassified as a “dwarf planet.” This had two main effects on our solar system: it reduced the number of recognized planets to eight, and left many Earthlings very sad. But Pluto’s demotion reignited a conversation that scientists have had since Neptune’s discovery: is there a “Planet X” orbiting the Sun that we don’t yet know about? In December 2018, astronomers announced they’d found the most distant object ever to be observed in our solar system....

Now, the better part of a year later, Microsoft has announced the pricing, specs, and availability for the Surface Duo. It’s up for pre-order today for $1,399, which is considerably cheaper than the full-sized Galaxy Z Fold, and matches the retail price of Samsung’s smaller, clamshell-style Galaxy Z Flip. The Surface Duo’s defining feature includes a pair of vertical, 5.6-inch screens attached with a hinge that allows them to operate as a makeshift 8....

But what players didn’t realize was that while ash bats might crack, maple has a tendency to snap sending splintered projectiles into the infield, the stands and the dugout. And snap is what it did last month when a chunk flew into a dugout and pierced the cheek of Pirates’ hitting coach Don Long. Suddenly, Major League Baseball is paying a bit more attention. Commissioner Bud Selig said that “very premature” discussions about the bats occurred last week at the owners’ meetings in Milwaukee, adding that “It’s been a source of concern for me....

No animal, including human beings, can survive without sleep. As far back as 1894, Russian physician and scientist, Marie de Manacéine found that when he kept puppies in constant activity with no amount of sleep, they died after only a couple of days. As for us humans, scientists and citizen scientists alike have deprived either themselves or their research participants of sleep for prolonged periods of time and all noted similar effects: A decrease in mental functioning, a lack of awareness and attention to the world around them, a distorted sense of time, and immense fatigue....

FACT: Madame CJ Walker’s “Wonderful Hair Grower” was a better, smarter version of dandruff shampoo By Purbita Saha There’s no denying that Madame CJ Walker was a genius. The self-taught chemist and self-made entrepreneur was born to two formerly enslaved Louisianans in 1867. At a young age, she took on a job as a laundress, which exposed her to harsh cleansers that made her hair fall out. Hair loss was a common issue among Black women in America in the 18th and 19th centuries....

Further, the FAA tweeted that “military training, limited staffing in one area of the Jacksonville en route center” may also be factors that are contributing to Friday’s delays and cancellations, and “some airlines continue to experience scheduling challenges due to aircraft and crews being out of place.” But while the FAA insists complications on its end were cleared up before the weekend, Southwest continued to struggle, canceling more than 1,800 flights across Saturday and Sunday....

“The baby formula shortage was a perfect storm,” explains Jenelle Ferry, neonatologist and director of feeding, nutrition, and infant development at Pediatrix Neonatology of Florida. “You had a combination of COVID pandemic restrictions, supply chain issues, and now you’re involving a situation with a company [Abbott Nutrition] that is a major manufacturer of formula products.” On February 17, 2022, the FDA sent out a warning to consumers to stop using powdered infant formula from Abbott Nutrition after concerns of bacterial contamination in its products....

What does 100-megapixels actually mean? When we talk about a camera’s megapixel count, we’re typically referring to the final resolution of the images it produces, which can be different from the number of photoreceptors on the camera’s sensor. The two numbers are often very close—and sometimes identical—but there are some variables. In the case of the GFX 100, the final images check in at a resolution of 11,648 x 8,736 pixels....

Is he right? Will allowing guns in schools make those schools safer? It hasn’t helped much in homes or on the street, researchers say, and evidence suggests that access to guns could actually exacerbate violence. A 2009 University of Pennsylvania study financed by the National Institutes of Health looked at the chances of being shot when holding a gun versus not holding a gun. In Pennsylvania, from 2003 to 2006, police sent the epidemiological researchers reports of gun-related assaults soon after they happened....

The C-4 Optics 4.9mm f/3.5 circular fisheye is unlike anything currently on the market. It’s a fisheye lens that creates a circular image on a typical full-frame image sensor, which is the same size as a frame of 35mm film. The lens has a 270 degree field of view, which means it can literally see behind itself. It’s not up for sale on Lens Authority for $39,000. “We set it on a stool in the workshop facing upwards and you could see the whole room,” says Roger Cicala, one of the world’s foremost experts on lens testing and founder of Lensrentals....

Civilization Revolution remains faithful to the game design launched seventeen years ago for MS-DOS computers with 16-color displays, but it feels remarkably fresh and accessible in its new keyboard- and mouseless incarnation. The game challenges players to start out with a single primitive outpost 6000 years ago and, by developing commerce, culture, technology and military might over the course of centuries, achieve global domination. The game proceeds by turns – you move your units, assign tasks to your minions, then sit back nervously while your opponents (live or computer-controlled) set their own machinations in motion....

We know what you’re thinking: love drones? Those ominous, free-floating, sometimes unseen killers that have walked our nation out onto some perilously thin ice, geopolitically and ethically? Even the word itself is loaded. No one can agree on what a drone is, exactly, or whether they should be referred to as drones at all. Turns out we don’t just think about drones. We have feelings about drones. But yes, there is plenty to love beyond the headlines about the Middle East....

No one wants to watch my 30-second struggle to focus a camera, or my kids arguing over which way the pants on LEGO characters go. This is where some simple editing can make the difference between cringe-worthy images and a polished video. If you’re already feeling intimidated, know there’s no need for expensive, high-end editing software, or delicate equipment that requires you to put another mortgage in your house. Basic video editing programs can be more than enough if you’re putting together slideshows, or mashing up vacation highlights....

Today marks the 30th anniversary of one of the greatest losses of life in spaceflight, the Challenger disaster, and is a time for all to reflect on the deaths that have accompanied one of the greatest human endeavors of our lifetimes. NASA is currently in mourning, marking its annual Day of Remembrance not only for the deaths of the seven astronauts who died aboard the Challenger on January 28, 1986, but also the three astronauts of Apollo 1, who perished in a fire January 27, 1967, and the seven astronauts who died when the Space Shuttle Columbia exploded upon re-entry on February 1, 2003....

The most recent nationwide data we have on sleep is from 2014, but it shows 35 percent of us aren’t getting the recommended seven hours. And there’s reason to believe that the COVID-19 pandemic and other stressors have made that problem worse. Research also shows bedroom environmental conditions affect the severity of sleep disorders such as obstructive sleep apnea. A few simple changes should have you dozing off faster in no time....
