FDA Approves First Prosthesis Controlled by Muscle Electrical Signals

Dean Kamen’s DEKA Arm is an electronic prosthetic that mimics natural arm and hand movement with an amazing level of finesse. It’s controlled by electrical signals from the wearer’s muscles. This week, the DEKA Arm became the first muscle-controlled prostheticapproved by the FDA for sale to the general public.
In the FDA study, 90% of test subjects were able to quickly adapt to using the DEKA Arm for tasks that were impossible with traditional arm prosthetics, like brushing hair and using keys and zippers.
This is a cyborg we can all support.

This is a picture I took with my phone at the Naturalis Biodiversity Center in Leiden, Netherlands. It is a scale showing how 1L (liter) of granite is lighter than 1L of basalt. This helps us visualize why plate tectonics never results in continents sinking underneath the ocean. Because continental crust is made of granite and oceanic crust is made of basalt, continents will never sink under the ocean because continents are always lighter than the ocean floor.
The pen is there for scale.

Those are fucking PHOTOS of molecules I dont fucking know how to react when I was in school they told me this shit is impossible look at this beauty you even see the doublebonding oh my fucking god tahts so fucking beautiful.

Scientists achieve reliable quantum teleportation for first timeEinstein is wrong? That’s the potential outcome of a quantum mechanics study as scientists race to disprove his views on entanglement.

Albert Einstein once told a friend that quantum mechanics doesn’t hold water in his scientific world view because “physics should represent a reality in time and space, free from spooky actions at a distance.” That spooky action at a distance is entanglement, a quantum phenomenon in which two particles, separated by any amount of distance, can instantaneously affect one another as if part of a unified system.

Now, scientists have successfully hijacked that quantum weirdness — doing so reliably for the first time — to produce what many sci-fi fans have long dreamt up: teleportation. No, not beaming humans aboard the USS Enterprise, but the teleportation of data.

Physicists at the Kavli Institute of Nanoscience, part of the Delft University of Technology in the Netherlands, report that they sent quantum data concerning the spin state of an electron to another electron about 10 feet away. Quantum teleportation has been recorded in the past, but the results in this study have an unprecedented replication rate of 100 percent at the current distance, the team said.

Thanks to the strange properties of entanglement, this allows for that data — only quantum data, not classical information like messages or even simple bits — to be teleported seemingly faster than the speed of light. The news was reported first by The New York Times on Thursday, following the publication of a paper in the journal Science.

Discovery shows that oceanic metabolic processes could have, over time, engendered the conditions necessary for RNA precursors to appear.

A graduate student who took a shortcut during a quality control procedure at the University of Cambridge accidentally discovered the first evidence of metabolism occurring outside a cell. The unexpected result may help to lift another veil on the mystery that is the origin of life.

The student, who was working in Markus Ralser’s lab, detected pyruvate in a cell culture medium that hadn’t been used yet. It shouldn’t have been there. Pyruvate is a product of glycolysis, the metabolic pathway that breaks down the sugar glucose in one of the many steps that lead to the production of ATP, the energy storing molecule that makes our cells tick…

Scientists create sensor for night vision contact lenses

It may seem like the stuff from spy and superhero movies but scientists have created “the first room-temperature light detector that can sense the full infrared spectrum” which, according to researchers at the University of Michigan, can be made so thin that it can be easily stacked on night vision contact lenses.
Back in 2011 some speculated that Seal Team Six used night vision contact lenses in the operation that killed Osama Bin Laden. Those rumors were never substantiated, but this invention is very real…

Scientists Successfully Implant Lungs into Fish
Scientists have successfully created a goldfish that is capable of breathing atmospheric air. Using advanced microsurgery techniques, researchers at the New South Wales Veterinary Institute implanted a pair of frog lungs into the fish, which survived out of water for 2 hours.
The lungs were connected to the respiratory surface that were naturally found in the gills. The fish was able to conduct gas exchange through the lungs instead of the gills, which allowed it to breath in a terrestrial environment. A very humid chamber was constructed for the goldfish so that it did not dehydrate.

Mathematical Beauty Activates Same Brain Region as Great Art or Music
People who appreciate the beauty of mathematics activate the same part of their brain when they look at aesthetically pleasing formula as others do when appreciating art or music, suggesting that there is a neurobiological basis to beauty.
There are many different sources of beauty – a beautiful face, a picturesque landscape, a great symphony are all examples of beauty derived from sensory experiences. But there are other, highly intellectual sources of beauty. Mathematicians often describe mathematical formulae in emotive terms and the experience of mathematical beauty has often been compared by them to the experience of beauty derived from the greatest art.

Scientists decipher dog-tail wags

Scientists have shed more light on how the movements of a dog’s tail are linked to its mood.
Earlier research had revealed that happy dogs wag their tails more to the right (from the dog’s point of view), while nervous dogs have a left-dominated swish.
But now scientists say that fellow canines can spot and respond to these subtle tail differences.
The study is published in the journal Current Biology.
Prof Georgio Vallortigara, a neuroscientist from the University of Trento, said: “It is very well known in humans that the left and right side of the brain are differently involved in stimuli that invokes positive or negative emotions.
"Here we attempted to look at it in other species."
He added that just as in humans, for dogs the right side of the brain was responsible for left-handed movement and vice versa, and the two hemispheres played different roles in emotions.
Dogs on film
To find out more about how dogs react to the lop-sided tail wags of other dogs, the researchers monitored the animals as they watched films of other dogs.
They measured the pets’ heart rates and analysed their behaviour.
Prof Vallortigara said: “We presented dogs with movies of dogs - either a naturalistic version or a silhouette to get rid of any other confounding issues, and we could doctor the movement of the tail and present the tail more to the left or right.”
When the animals saw an otherwise expressionless dog move its tail to the right (from the tail-wagging dog’s point of view), they stayed perfectly relaxed.
But when they spotted a tail veer predominantly to the left (again from the tail-swishing dog’s point of view), their heart rates picked up and they looked anxious.
Prof Vallortigara said he didn’t think that the dogs were intentionally communicating with each other through these movements.
Instead, he believes that they dogs have learned from experience what moves they should and shouldn’t feel worried about.
