If you missed your chance to seed your lawn last fall, don’t worry. You don’t have to suffer through a summer of terrible grass. You can get your lawn back in shape with an early-spring seeding. Remove the Old LawnStart by digging up and removing all traces of the old lawn. If the area is small enough‚ say, 150 square feet or less‚ you can use a flat-blade shovel or manual sod cutter....
Whether you’re selling it, trashing it, or reusing it, your old computer has a bunch of extremely private data stored inside. And there’s a good chance that tossing files in the recycling bin and hitting factory reset won’t protect you. If a hacker finds the pattern your computer used to move those 0s and 1s around, they can reverse engineer the original state of your computer and pull out the goods....
When I’m running to a volunteer job or helping out a friend, I can’t take everything with me. And since I don’t always know exactly what we’ll be doing, I have to improvise. I need tools that can handle wood, metal, and plastic. PVC and sheet metal. I prefer cordless tools, because you never know what the power supply will be, but my heavy-duty tools are corded. After decades of refinement, this is the most versatile group of tools I’ve discovered....
Long Island man Gerard Chasteen shot a Mavik 2 Zoom drone out of the sky over his home in St. James with a shotgun on Saturday, local police tell he New York Post. The drone, being flown by Lynn Fodale and Teddy Henn, was on a mission to find a lost dog named Dezie when it was felled by Chasteen, who is now being charged with third-degree criminal mischief and prohibited use of a weapon....
For some people, math can be a necessary headache. Yes, algorithms guide countless aspects of daily life. There are tips to calculate and hours to count. But unless someone’s a specialist, they’ll probably ignore complex math in any given situation if they can help it.But Yale assistant professor of mathematics Stefan Steinerberger wants to challenge that perception. His new study shows that an average American can assess mathematical arguments for beauty just as they can pieces of art or music....
The hard truth of crowdfunding is that campaigns fail all the time. Sometimes they never deliver, sometimes they deliver poorly. Usually you get something for your money either way, even if it’s a partial refund or a subpar product. But every now and then there’s a fail that just completely wipes out. Take the IndieGogo campaign for the PopSlate 2 phone case. Once a million-dollar crowdfunding darling, it’s now bankrupt, and there are no refunds for the backers caught in the crossfire....
Civic-MindedHonda injects the market with not just one but four new flavors of its popular compact Civic.The Honda Civic is largely responsible for the iconic grip small Japanese cars have on the American carbuyer. Early on, it defined compact, well-built, counterculture transportation, delivering qualities that the Big Three carmakers failed to acknowledge. For 2006, Honda has a family of new Civics. The Sedan is longer and wider, powered by a 140-hp 1....
Scientists at Stanford have made a working prototype particle accelerator smaller than a human hair.Shrinking particle accelerators is a high-priority goal because of the potential in applications outside of laboratories. A computer designed this accelerator to efficiently harness and direct micro beams of light.Scientists have made a particle accelerator so small, it’s just half the diameter of a human hair. Their goal was to make an accelerator that could fit on an integrated chip, and they did it by allowing a computer to design the chip....
The U.S. Military released more video today of an incident involving a Russian fighter jet and a U.S. Navy spy plane. The video clearly shows the Sukhoi Su-27 jet fighter, bristling with missiles, flying much too close to the EP-3 Aries reconnaissance aircraft for comfort. The videos, released this morning by the YouTube account of Commander, U.S. Naval Forces Europe-Africa/U.S. 6th Fleet, show the Su-27 (NATO code name: Flanker) twin engine fighter extremely close to the EP-3 aircraft....
An international team of scientists have discovered what they claim is the earliest animal fossil footprint on record. The tracks were created in mud up to 551 million years ago somewhere in the mountainous Yangtze Gorges, by the Yangtze River in southern China.That timeline would place the tracks in the Edicaran Period, making them the first animal prints found from that time in history. Edicaran fossils are typically soft bodied tubes and frond-shaped organisms known as biota....
One of the most familiar shapes in science is DNA’s double helix structure. First discovered in 1953, this structure uncovered a wealth of information about our genes and the DNA molecules that encode them.But new research published in the journal Nature Chemistry says DNA isn’t always in a double helix form and can sometimes take the shape of what scientists call an “i-motif.” While scientists have been able to create an i-motif DNA structure in the lab for a few years now, this new research confirms that it can also occur naturally inside human cells....
Medical researchers at the Massachusetts General Hospital (MGH) have successfully used stem cells to grow functioning heart tissue, a major step toward bioengineering organs for people in need of a transplant. Growing organs from a patient’s own genetic material could potentially eliminate the need for a donor and reduce the risk of the patient’s immune system rejecting the transplanted organ. A technique using messenger RNA was used to revert skin cells to stem cells....
Israeli nonprofit SpaceIL successfully inserted its spacecraft, Beresheet, into the moon’s orbit yesterday—and they have the photos to prove it.Late night the spacecraft’s moon-capture maneuver caught these stunning photos of the far side of the moon. One photo is a close up of the surface, taken at a height of 470 km. The other photo captures part of the far side of the moon with Earth in the background. View full post on TwitterThe far side of the moon is rarely seen, since the moon is tidally locked, but the “dark” side of the moon has been captured few times before....
Space changes a person, but not as much as you might think. That’s the lead result from NASA’s major Twins Study, a yearlong project that examined identical twin astronauts Scott and Mark Kelly after Scott’s year spend on the International Space Station, looking for differences between the brothers to see how space would effect the human body. While scientists caution that much more study is needed, the Twins Study offers a baseline of optimism for extended manned space travel....
Few things are more American than setting off fireworks on the 4th of July. They’re the centerpiece of the holiday—most Independence Day celebrations end with a dazzling display of fireworks lighting up the sky in a mix of bright colors and booming explosions. Because we associate fireworks with the 4th, you might be surprised to learn that they’re not an American invention but a Chinese one and their origins began more than 2,000 years ago....
The U.S. Navy’s newest warships, the Zumwalt-class guided missile destroyers, are undergoing a major mission change. Once meant to support land forces by bombarding targets dozens of miles inland, the destroyers will now hunt enemy warships for a living. The change reflects a shift in strategic realities as the Russian and Chinese navies grow larger and more powerful.Way back in the 2000s, the U.S. Navy decided it wanted a new class of destroyer that could support the land wars of the post 9/11 era....
Humans have been building fire the right way for thousands of years – and now we have the math to prove it.Adrian Bejan, a mathematics professor at Duke University, wanted to determine scientifically what is the best way to build a fire. This research has shown that the best method uses a pyramid that’s as wide as it is tall. “The reason is that this shape is the most efficient for air and heat flow,” Bejan said in a press release....
Speed TestMachinist Mike Conlon at Brooklyn, N.Y.’s Caliper Studio put three bits through an inch-thick bar of 304 stainless steel and into a polyurethane bowling ball. The bit with the fastest average time won.Bosch: Bosch bits came through the back side of the bar in 1 minute, 11 seconds on average. The fastest trial was just 32.8 seconds. Burrowing the length of the bit into the ball took 3 seconds.Irwin: Conlon averaged 1:44 boring through the steel....
The Trump administration plans to end “direct” federal funding of the International Space Station to free up funds for lunar exploration goals, as reported by Loren Grush at The Verge. A draft budget proposal from the White House Office of Management and Budget (OMB) leaked to The Verge and other publications states a space exploration objective as, “Ending direct federal government support of the ISS by 2025 and transitioning to commercial provision of low Earth orbit (LEO) capabilities....
Media Platforms Design TeamHow involved were you with adapting the comic for the show? Robert Kirkman (author, producer): Well I don’t want to diminish Frank’s involvement at all because Frank every step of the way, at least for the first two episodes, was one hundred percent the guy adapting this. But, yeah, I’m an executive producer on the show. I wrote the script for the fourth episode. Frank Darabont (producer, director): It’s good, too....
