Cyclists Shine at Night Courtesy of New Reflective Spray

By Carl Engelking | March 30, 2015 2:02 pm


Riding a bicycle is a great way to get in shape while getting from point A to point B. But it also can be dangerous — especially at night.

In 2012, 45,000 cyclists were injured or killed on roads in the United States, with 29 percent of those injuries occurring from collision with a vehicle. Many times, drivers simply don’t see a bicyclist until it’s too late. That’s why Volvo has come up with a unique way to make cyclists stand out: transparent reflective spray. It’s invisible by day, and potentially life-saving by night. Read More

Rare, Adorable Pika Photographed For First Time in Decades

By Carl Engelking | March 27, 2015 12:25 pm


If you went out searching for the Ili pika in the moutains of China, odds are your search would be fruitless. And that’s a darn shame.

Seriously, look at that cuddly distant relative of the rabbit.

Sadly, Ili pikas are “vulnerable to extinction” according to the International Union for Conservation of Nature, and as such, no one has seen the little critters for two decades. But last July, Li Weidong, the man who discovered the creatures in 1983, was reacquainted with an old fuzzy friend while climbing through the Tian Shan Mountains in central China. With his camera in tow, he made sure to snap the first picture of an Ili pika since Bill Clinton was president.

Why Cold Cities Have More Exploding Manhole Covers

By Carl Engelking | March 27, 2015 11:24 am


In cold-weather cities in the U.S., slush, snow and wind aren’t the only inconveniences to contend with when the temperature drops; there’s also this small matter of exploding manholes.

Public works officials in New York City have fielded thousands of blown manhole reports throughout late 2014 and into this year, and crews in Indianapolis, weeks before hosting the Final Four, just installed locking manhole covers after two explosions were reported in highly trafficked areas. Similar stories are popping up — pun intended — around the country. Read More

NASA is about to take yet another bold step toward sending humans to Mars.

At 3:42pm Eastern time tomorrow afternoon, NASA astronaut Scott Kelly will strap into a Russian rocket and kiss Earth goodbye for an entire year to live on the International Space Station. Meanwhile, his identical twin Mark, a retired NASA astronaut himself, will stay here on Earth. Both men, though serving on vastly different fronts, are the guinea pigs in a big-time NASA study that will examine the physical and psychological effects of extended stays in space. Read More

Super Slippery Bottle Means You Won’t Waste a Drop of Glue

By Carl Engelking | March 24, 2015 2:42 pm


Glue is so good at sticking to things that it inevitably clings to the one place we need it the least: the inner wall of the bottle. But after more than 65 years holding school art projects together, one of the leading glue manufacturers has found a way out of this sticky situation.

Elmer’s will coat the inside of their bottles with a new, super-slick coating that will ensure every last drop goes where you need it. The company recently signed an exclusive license with LiquiGlide, the makers of a magically slippery substance. Read More

Wood Bison Roam the U.S. for First Time in a Century

By Carl Engelking | March 23, 2015 2:41 pm

wood bison

After vanishing from their wild habitats over a century ago, wood bison, the largest land mammals native to North America, now roam freely in Alaska once again.

The first group of 30 juvenile wood bison arrived in the rural Alaskan village of Shageluk after making a one-hour flight from the Alaska Wildlife Conservation Center on Sunday. Over the next several weeks, 70 more wood bison will make the same trip before ultimately being released as a herd into the Inoko Flats — the same lands their ancestors thundered upon for thousands of years.

Promising Alzheimer’s Drug Slows Cognitive Decline

By Carl Engelking | March 20, 2015 1:57 pm


The search for an effective treatment for Alzheimer’s disease has been riddled with failures, but a promising new drug could serve as a rare success story for those living with mild forms of the condition.

Biogen Idec, a Massachusetts-based company, announced Friday that a drug they’re testing effectively slowed the mental decline of some patients and reduced levels of amyloid plaques in their brains. Although the results are from an early-stage study, they offer hope of finding the so far elusive drug to battle the underlying causes of the disease. Read More

Radical New 3-D Printer Grows Objects from Goo

By Carl Engelking | March 17, 2015 1:34 pm

clip 3d printer

It seems hard to believe, but we may already need to start differentiating between “old-fashioned” and modern 3-D printing methods.

Silicon Valley startup Carbon3D has emerged from two years of strategic hiding to blow our minds: Engineers there designed a 3-D printer that makes intricate objects, like a miniature Eiffel Tower, rise from a primordial pool of resin. Apart from looking awesome, Carbon3D’s technique also prints smoother objects and does it 25 to 100 times faster than 3-D printers currently on the market. Read More

How to Propel Tiny Satellites? Just Add Ice

Ice is a pretty all-around useful chemical, but generally for mundane things: chilling drinks, skating on, mending swollen joints. But some scientists have a far sexier purpose in mind for ice as rocket fuel.

CubeSats, introduced in the early 2000s, are music-box-sized satellites that are democratizing space research because they are tiny, inexpensive and can perform myriad tasks. For all their versatility, CubeSats have a glaring flaw: Engineers are hard-pressed to fit a propulsion system into CubeSats’ already compact designs. But a team from the Netherlands believes it has solved the problem by building an ice-propelled rocket. Read More
