Researchers at Eindhoven University in the Netherlands have recently grown synthetic pork meat in a laboratory setting. Lois Rogers writes for The Times:The advent of so-called “in-vitro” or cultured meat could reduce the billions of tons of greenhouse gases emitted each year by farm animals — if people are willing to eat it.
So far the scientists have not tasted it, but they believe the breakthrough could lead to sausages and other processed products being made from laboratory meat in as little as five years’ time.
They initially extracted cells from the muscle of a live pig. Called myoblasts, these cells are programmed to grow into muscle and repair damage in animals.
The cells were then incubated in a solution containing nutrients to encourage them to multiply indefinitely. This nutritious “broth” is derived from the blood products of animal foetuses, although the intention is to come up with a synthetic solution.
The zoo of Warsaw, Poland, has a pair of prehistoric humans (or actors depicting them) on display over the weekend:Organiser Maria Mastalerz says the weeklong "performance" aims to attract interest in a play, "Caveman," showing in the Polish capital. But she says it also carries a message that humans today are not all that different from their prehistoric ancestors.
Dressed in furs and animal skins, the young woman and man smoked a fish over a fire Friday, poking it with a stick, or stared from behind bars at startled zoo visitors.
The wording [on the back] is my favorite part. It reads: '[We] request the honor of your presence as two geeks save the princess, resist the dark side and pledge their lives (extra, or otherwise) to each other.' And we snuck a Hyrulian crest in there too!
Researchers at the University of Bristol in England hope to deploy the poodle-size ‘bot in search-and-rescue missions where vision is impaired, like in mines or smoky rooms. Its 18 whiskers move back and forth five times per second. When a whisker bends, a sensor on its shaft signals software to orient the ’bot toward the object. Whiskers close to an object move less, while those farther away make wide, sweeping motions to establish the object’s exact edges.
Scottish brewery BrewDog has released its newest beer, named Tactical Nuclear Penguin. At 32% alcohol content, it's the world's strongest beer:A warning on the label states: "This is an extremely strong beer; it should be enjoyed in small servings and with an air of aristocratic nonchalance. In exactly the same manner that you would enjoy a fine whisky, a Frank Zappa album or a visit from a friendly yet anxious ghost."
However Jack Law, of Alcohol Focus Scotland, described it was a "cynical marketing ploy" and said: "We want to know why a brewer would produce a beer almost as strong as whisky."
The beer has been launched on the day alcohol was at the top of the political agenda with the unveiling of the Scottish government's Alcohol Bill including proposals for minimum pricing on drink.
A solid dissection puzzle invented by Piet Hein during a lecture on Quantum Mechanics by Werner Heisenberg. There are seven soma pieces composed of all the irregular face-joined cubes (polycubes) with *=4 cubes. The object is to assemble the pieces into a cube. There are 240 essentially distinct ways of doing so (Beeler 1972, Berlekamp et al. 1982), as first enumerated one rainy afternoon in 1961 by J. H. Conway and Mike Guy.
By "frame accurate" we mean that we took all of the video frames from that part of the movie (that's nearly 900 frames for just 44 seconds of footage) and reproduced them all in Lego.
This was time-consuming to say the least, taking us something like 440 hours to make the completed movie. At that ratio of 10 hours per second we figured we could do the whole film in about 9 years, so long we didn't need to eat or sleep. As a full-time job then, we're probably looking at 25 years or so. No thanks.
Early in the piece we decided we wanted to do everything "in camera". No wire-removal, no special effects, no crazy Photoshop tricks. We pretty much regret this now, but I guess it gives us bragging rights of some sort. We did do some colour correction and image stabilising, and at one point we edited a very small number of frames in one scene so that some minor background shake was taken out, but that's it.
A door-opening robot must be able to grasp a variety of designs of door knobs and handles. It also needs to calculate "how much force is needed to open the door, the twisting angles to unlatch the door, and how much force is needed to unlatch it", says Erin Rapacki, now at Anybots in Mountain View, California [...]
To keep her device simple, Rapacki used a single motor and avoided the expense of cameras and elaborate sensors. Instead, a motor-driven set of gears extends the gripper towards the handle with its three fingers spread apart (see diagram).
Rapacki first tried flexible neoprene fingers, thinking that they could bend to grasp the knob, but these proved too thick and soft. Stiff plastic fingers with plates to constrain their sideways motion proved much more effective.
She also added a slip clutch to the drive system, to allow the device to hold and turn the knob at the same time as pushing or pulling.
