Researchers Grow Organs In The Lab

Lab Grown Ears
In 1996 scientists built a human bladder and since then, they have been building increasingly more complex organs. There have been five windpipe replacement operations so far. Lab-grown tear ducts and an artery have been transplanted into patients.

This article in the Wall Street Journal highlights scientists that are working on a heart, among other organs. Growing a heart is much more difficult than a windpipe, as the heart is larger and has several types of cells, including those that beat, those that form blood vessels, and those that help conduct electrical signals.

A shortage of human organs for transplant has spurred research into "building" them.

Fun Time! Arctic Force Snow Crossbow By Wham-O!

The name Wham-O has great meaning for folks my age. The purveyor of some of the most wonderful toys of my childhood. Whether it was a Slip-n-Slide or a Frisbee, Wham-O had the goods.

Behold their next great achievement: the Arctic Force Crossbow!

Imagine getting smacked with a snowball shot from one of these.

Yeah, it's spring and it will just sit unused until next winter (here in the northern hemisphere, at least), but I'd grab one now before there's a run on them next November.

World's First Electric Tilt Rotor Aircraft

Oh, now doesn't this look sexy? With all the hoopla about flying cars, it's understandable that this beauty might not get noticed.

From AugustaWestland comes this gorgeous, tilt-rotor aircraft. Vertical take off and landing, check. Sci-fi styling, check. Powered by rechargeable batteries, check.

Only thing we need now is an affordable two-seater.

We Have Grossly Underestimated Both The Scope And Scale Of Animal Intelligence

This article in the Wall Street Journal brings to light research that shows animals are FAR more intelligent than we've ever imagined. One of the main issues is that we test animal intelligence in ways that work well for  humans, but not so much for the animals.

From the article..."Elephants are a perfect example. For years, scientists believed them incapable of using tools. At most, an elephant might pick up a stick to scratch its itchy behind. In earlier studies, the pachyderms were offered a long stick while food was placed outside their reach to see if they would use the stick to retrieve it. This setup worked well with primates, but elephants left the stick alone. From this, researchers concluded that the elephants didn't understand the problem. It occurred to no one that perhaps we, the investigators, didn't understand the elephants. Think about the test from the animal's perspective. Unlike the primate hand, the elephant's grasping organ is also its nose. Elephants use their trunks not only to reach food but also to sniff and touch it. With their unparalleled sense of smell, the animals know exactly what they are going for. Vision is secondary. But as soon as an elephant picks up a stick, its nasal passages are blocked. Even when the stick is close to the food, it impedes feeling and smelling. It is like sending a blindfolded child on an Easter egg hunt."

Perhaps my favorite line from the article states it best.

"Experiments with animals have long been handicapped by our anthropocentric attitude."

Yeah, but isn't that the source of almost all our problems?

Human Powered Helicopter Project

There's a competition going on to develop the world's first human powered helicopter. The Sikorsky Company is sponsoring it and there's a $250,000 prize for winning. The vehicle has to fly for 60 Seconds, make it 9.8 feet above the ground and stay within a 10-Square meter area. For more information, here's a link.

Kenneth Huff, Neal Fischer and William Edwards want to win that prize. With a $5,000 development grant from Middle Georgia State College they have built several prototype craft. To raise the rest of the needed funds to complete the helicopter, they've gone to Kickstarter.

With only seven days and $19,681 to go, their Kickstarter project might not get funded, but it's an idea that will still eventually get off the ground someday.

Jeremy Grantham Says Billions Are Going To Starve To Death

Almost 200 years ago Thomas Malthus opined about the effects of unchecked population growth. He worried that human populations, which grow exponentially, would eventually crash and go back to subsistence conditions because food production would grow at a linear pace. "The power of population is indefinitely greater than the power in the earth to produce subsistence for man," he wrote.

Jeremy Grantham believes that we have finally and permanently outstripped the planet's ability to support us. For the last hundred years or so, we have cheated that by using fertilizer, phosphorus in particular. Now, just like oil, we are about to reach peak phosphorus production.

Here's a link to the article in Business Insider. There are lots of charts to bolster Grantham's view.
