1. Robotic gripper runs on coffee … and balloons – The human hand is very complex and replicating it is very challenging. But now researchers have found out how to mechanically replicate it McGyver style with common household objects, ground coffee and a latex party balloon.
“This is one of the closest things we’ve ever done that could be on the market tomorrow,” Lipson said. He noted that the universality of the gripper makes future applications seemingly limitless, from the military using it to dismantle explosive devises or to move potentially dangerous objects, robotic arms in factories, on the feet of a robot that could walk on walls, or on prosthetic limbs.
Here’s how it works: An everyday party balloon filled with ground coffee — any variety will do — is attached to a robotic arm. The coffee-filled balloon presses down and deforms around the desired object, and then a vacuum sucks the air out of the balloon, solidifying its grip. When the vacuum is released, the balloon becomes soft again, and the gripper lets go.
2. New films lead to skeptical articles about psychics. Two current films in theaters now involve alleged psychics who claim to be able to talk to the dead, Clint Eastwood’s Hereafter and Woody Allen’s You Will Meet a Tall Dark Stranger. Now I’ve only seen the Woody Allen film because (A) Eastwood tends to make boring films and (B) I don’t find dialogue like “It’s not a gift; it’s a curse” particularly profound or, you know, original. Also, Allen’s film was fairly unapologetically skeptical while Eastwoods (and maybe I’m wrong) looks less so. But what I find interesting is that both films have led to interesting skeptical articles about psychic claims, one an interview with Woody Allen, where he reiterates his atheism, and the other, a review by Roger Ebert of Hereafter.
3. Two really great pieces of athvertising:

Don't hate me because I'm beautiful.
1. Another study allegedly suggests beautiful women make men stupid –
Just five minutes alone with an attractive female raise the levels of cortisol, the body’s stress hormone, according to a study from the University of Valencia.
The effects are heightened in men who believe that the woman in question is “out of their league”.
Researchers tested 84 male students by asking each one to sit in a room and solve a Sudoku puzzle. Two strangers, one male and one female, were also in the room.
When the female stranger left the room and the two men remained sitting together, the volunteer’s stress levels did not rise. However, when the volunteer was left alone with the female stranger, his cortisol levels rose.
The researchers concluded: “In this study we considered that for most men the presence of an attractive woman may induce the perception that there is an opportunity for courtship.
I don’t know how this became a hot topic in scientific research. Maybe a few too many lonely male scientists are out to prove women are evil or will be the downfall of civilization.
2. How to create lesbian mice – That’s not what I’m personally into but apparently if one were so inclined to turn female mice into lesbians, all it takes is deleting a single gene. Of course the rodent religious right will still continue to insist that it’s just the choice to live a sinful lifestyle and reject the teachings of the mouse messiah. Why else would they call the aforementioned gene “FucM”? Mickey wants you to repent! He died for your sins.
Begin operation kill all humans.
3. Robot Ranger sets untethered walking record –
A Cornell University robot named Ranger walked 14.3 miles in about 11 hours, setting an unofficial world record at Cornell’s Barton Hall early on July 6. A human — armed with nothing more than a standard remote control for toys — steered the untethered robot.
The 14.3-mile record beats the former world record set by Boston Dynamics’ BigDog, which had claimed the record at 12.8 miles.
Sure, it can walk on a track but how’d it do in the rocky terrain of Tatoine?
4. Ben Stein tells the unemployed to get a job -Here’s what Stein had to tell America’s unemployed:
The people who have been laid off and cannot find work are generally people with poor work habits and poor personalities. I say “generally” because there are exceptions. But in general, as I survey the ranks of those who are unemployed, I see people who have overbearing and unpleasant personalities and/or who do not know how to do a day’s work. They are people who create either little utility or negative utility on the job.
And this was Nixon’s speech writer! I didn’t think it was possible but Stein seems to understand less about the job market than he does about biology and history.
