To keep hackers away from implanted devices, researchers use the heartbeat as a password To keep hackers away from implanted devices, researchers use the heartbeat as a password Just like a phone or computer, devices implanted inside the body can be hacked; potentially with life-threatening consequences. It’s not a common occurrence, but researchers are keen on taking protective measures now instead of later. A new system out of Rice University uses a combination of a patient’s heartbeat and a medical care provider’s touch as a password before allowing access to an implant. “If you have a device inside your body, a person could walk by, push a button and violate your privacy, even give you a shock,” graduate student Masoud Rostami said in a release.

Next, they sent the genetic instruction to the biological lab Agilent Technologies in California. Agilent constructed pieced together DNA strands made of the bases, according to Goldman and Birney's instructions. Then, the lab shipped the scientists a tiny vial.

First Bionic Eye Sees Light of Day in U.S.

After years of research, the first bionic eye has seen the light of day in the United States, giving hope to the blind around the world. Developed by Second Sight Medical Products, the Argus II Retinal Prosthesis System has helped more than 60 people recover partial sight, with some experiencing better results than others. Consisting of 60 electrodes implanted in the retina and glasses fitted with a special mini camera, Argus II has already won the approval of European regulators. The US Food and Drug Administration is soon expected to follow suit, making this bionic eye the world's first to become widely available.

Scientists Have Created a Microscopic Tractor Beam
University of Michigan News Service | Super-fine sound beam could one day be an invisible scalpel University of Michigan News Service | Super-fine sound beam could one day be an invisible scalpel ANN ARBOR—A carbon-nanotube-coated lens that converts light to sound can focus high-pressure sound waves to finer points than ever before. The University of Michigan engineering researchers who developed the new therapeutic ultrasound approach say it could lead to an invisible knife for noninvasive surgery. Today's ultrasound technology enables far more than glimpses into the womb. Doctors routinely use focused sound waves to blast apart kidney stones and prostate tumors, for example. The tools work primarily by focusing sound waves tightly enough to generate heat, says Jay Guo, a professor of electrical engineering and computer science, mechanical engineering, and macromolecular science and engineering.
An international team of engineers, physicists, and chemists have created the first fiber-optic solar cell. These fibers are thinner than human hair, flexible, and yet they produce electricity, just like a normal solar cell. The US military is already interested in weaving these threads into clothing, to provide a wearable power source for soldiers. In essence, the research team started with optical fibers made from glass — and then, using high-pressure chemical vapor deposition, injected n-, i-, and p-type silicon into the fiber, turning it into a solar cell.

Scientists Invent Vanishing Electronics That Dissolve in the Body : Science/Tech : Medical Daily Scientists have created ultra-thin electronic devices that can "melt away" in the body once their job is done. A new study, published in the journal Science, details how scientists have created a tiny, fully functional electronic device capable of vanishing within their environment, like in the body or in water, once they are no longer needed or useful. There are already implants that dispense drugs or provide electrical stimulation but they do not dissolve. The latest creation is an early step in a technology that may benefit not only medicine, like enabling the development of medical implants that don't need to be surgically removed or the risk of long-term side effects, but also electronic waste disposal.

Researchers Create First Working Qubit Based on Single Atom in Silicon Researchers Create First Working Qubit Based on Single Atom in Silicon By Will Soutter This is an artist’s impression of a phosphorus atom (red sphere surrounded by electron cloud, with arrow showing the spin direction) coupled to a silicon single-electron transistor. A burst of microwaves (blue) is used to ‘write’ information on the electron spin. (credit: Tony Melov) Qubit is the fundamental data unit of future quantum computers.
LG Chem, a member of the LG conglomerate/chaebol and one of the largest chemical companies in the world, has devised a cable-type lithium-ion battery that’s just a few millimeters in diameter, and is flexible enough to be tied in knots, worn as a bracelet, or woven into textiles. The underlying chemistry of the cable-type battery is the same as the lithium-ion battery in your smartphone or laptop — there’s an anode, a lithium cobalt oxide (LCO) cathode, an electrolyte — but instead of being laminated together in layers, they’re twisted into a hollow, flexible, spring-like helix. LG Chem’s battery starts with thin strands of copper wire, which are coated with a nickel-tin (Ni-Sn) alloy to create the anode. LG produces the first flexible cable-type lithium-ion battery LG produces the first flexible cable-type lithium-ion battery
THE hottest new material in town is light, strong and conducts electricity. What's more, it's been around a long, long time. Nanocrystalline cellulose (NCC), which is produced by processing wood pulp, is being hailed as the latest wonder material. Japan-based Pioneer Electronics is applying it to the next generation of flexible electronic displays. IBM is using it to create components for computers. Even the US army is getting in on the act, using it to make lightweight body armour and ballistic glass. Why wood pulp is world's new wonder material - tech - 23 August 2012

SExpand This may seem like something out of a science fiction movie: researchers have designed microparticles that can be injected directly into the bloodstream to quickly oxygenate your body, even if you can't breathe anymore. It's one of the best medical breakthroughs in recent years, and one that could save millions of lives every year. The invention, developed by a team at Boston Children's Hospital, will allow medical teams to keep patients alive and well for 15 to 30 minutes despite major respiratory failure. This is enough time for doctors and emergency personnel to act without risking a heart attack or permanent brain injuries in the patient. The solution has already been successfully tested on animals under critical lung failure.

Scientists Invent Particles That Will Let You Live Without Breathing

Neuroengineers at MIT have created a implantable fuel cell that generates electricity from the glucose present in the cerebrospinal fluid that flows around your brain and spinal cord. In theory, this fuel cell could eventually drive low-power sensors and computers that decode your brain activity to interface with prosthetic limbs. The glucose-powered fuel cell is crafted out of silicon and platinum, using standard semiconductor fabrication processes. The platinum acts as a catalyst, stripping electrons from glucose molecules, similar to how aerobic animal cells (such as our own) strip electrons from glucose with enzymes and oxygen.

Meeko the calf stood nuzzling a pile of hay. He didn't seem to have much appetite, and he looked a little bored. Every now and then, he glanced up, as though wondering why so many people with clipboards were standing around watching him. Fourteen hours earlier, I'd watched doctors lift Meeko's heart from his body and place it, still beating, in a plastic dish. No Pulse: How Doctors Reinvented The Human Heart
