TABLE SAW HORROR STORIES ABOUND. IF YOU'VE never had a mishap with one of these machines, count yourself among the blessed few. I've worked with countless men with scars and missing fingers, and I've had my share of close calls. Decades ago, I worked at a lumberyard where the foreman told me to be careful using the table saw that was about to become my main work station. "The last guy," he said, "lost four fingers." It was a shame, he said, the guy was so young.
You might expect this tale from a lumberyard, most of which are pretty rough places. But the need for safety in the home workshop is no less urgent. People who spend all week behind a desk may be ill-prepared to step behind a table saw on the weekend. That's why we named the SawStop Compact Table Saw ($899) a Tool Award winner this year. With a tabletop measuring 23 inches wide by 22% inches deep and weighing only 68 pounds, it's perfect for the home workshop or contractors who need a lightweight mobile table saw.
Most important, it's equipped with an industrial-duty safety feature: Its blade will stop in a fraction of a second and retract below the table if it contacts human flesh.
Introduced in the early 2000s, SawStop set out to put an end to table saw horror stories. When I saw it demonstrated in 2000 at the International Woodworking Fair in Atlanta, Georgia, I was flabbergasted. By then, I had already used saws of every size, shape, and description, from large and well-maintained machines in cabinet shops to wobbly little monsters propped up on sawhorses. There was even a big four-blade behemoth powered by a leather belt and a gigantic floor-mounted motor.

Henrietta Lacks - It's not surprising that Henrietta Lacks-whose
It's not surprising that Henrietta Lacks-whose "immortal" HeLa cells were pivotal in developing treatments for diseases such as polio, HIV/AIDS, and COVID19-is referred to as "the mother of modern medicine." But Lacks's legacy is complicated due to the ethical concerns surrounding the use of her special cells. Lacks, who died of cancer at age 31 in 1951, was never aware that her cells led to significant medical advancements or that they had been taken without her consent. And even now, her strange case raises questions about the morally dubious methods through which we achieved unquestionably positive breakthroughs in medicine.
Chasing an Asteroid - How NASA defied incredible odds to get its asteroid-hunting osiris-rex mission off the ground and in the process upended what we know about our solar system.
Dante Lauretta sat in the backseat of a helicopter hovering high above a remote patch of Utah desert, waiting for a small, twinkling speck in the sky to plunge toward earth.If you didn't know better, you might think what was beginning to burn through the skies above the American southwest in the early hours of September 24, 2023, was a shooting star. But it wasn't a shooting star. Or a meteor. It was a dishwasher-size capsule filled with bits of ancient asteroid-priceless matter from the dawn of the solar system. In other words, it was a treasure chest moving at 27,000 miles per hour and sizzling at a temperature half that of the sun's surface.
Whether We Live in a Simulation - scientist Melvin Vopson, PhD, studies this exact thing- the possibility that the universe might indeed be a digital facsimile. And he claims to have evidence.
In the 1999 film the Matrix, Neo discovers A truth to end all truths-the universe is a simulation. While this premise provides fantastic sci-fi fodder, the idea isn't quite as relegated to the fiction section as one might expect. . In fact, University of Portsmouth scientist Melvin Vopson, PhD, studies this exact thing- the possibility that the universe might indeed be a digital facsimile. And he claims to have evidence.
The Ancient Language of Easter Island - Today, humans inhabit- or have, at the very least, explored- pretty much every corner of the planet. But that immense proliferation of Homo sapiens across the globe was a slow process.
With the first humans leaving Africa between 60,000 and 120,000 years ago, the species slowly spread across the Earth over many millennia. And one of the last places these ancient humans made their way to was the southeastern Pacific island of Rapa Nui, known more broadly as Easter Island.Located 2,360 miles off the coast of Chile, Rapa Nui is one of the most isolated places in the world. Its native people, who are also named the Rapa Nui, first arrived on the island's shores between A.D. 1150 and 1280, and lived in isolation until the arrival of Dutch navigator Jacob Roggeveen in 1722.
Underwater UFOs - A retired U.S. Navy admiral believes that the government should look to the oceans to help solve a mystery in the skies.
A retired U.S. Navy admiral believes that the government should look to the oceans to help solve a mystery in the skies. Rear Admiral Timothy Gallaudet, former Oceanographer of the U.S. Navy, recently published a paper arguing that unidentified anomalous phenomena (UAP, more commonly referred to as UFO) and unidentified submersible objects (USO) are linked, and should be studied further.
Synching Up Our Circadian Rhythms - If you've ever done any kind of long-distance travel, or just woken up feeling under-rested thanks to daylight saving time, you know how important your circadian clock is.
If you've ever done any kind of long-distance travel, or just woken up feeling under-rested thanks to daylight saving time, you know how important your circadian clock is. Like many things in your body, your circadian rhythm is more complicated than it might seem on the surface. Rather than being entirely brain-based, it's actually controlled by a collection of several circadian clocks (central and peripheral) that all work together to keep your gears turning like a well-oiled machine.
