Robots and bio-printing change the face of surgery in UAE

Posted by in categories: 3D printing, bioprinting, biotech/medical, government, health, robotics/AI

Highly sophisticated robotics and ‘bio-printing’ are rapidly changing the face of modern surgery, significantly eliminating the risk of human error and in some cases even allowing doctors to perform procedures remotely, according to experts at Arab Health.

Dr Peter C.W. Kim, vice-president and associate surgeon-in-chief of the Joseph E. Roberts Jr. Centre for Surgical Care at Washington DC’s Children’s National — which has received millions of dollars in donations from the UAE’s government — noted that doctors will soon be able to 3D-print using bio-tissue, such as for an eardrum.

“What our engineers and researchers have done is not only design the plastic with it, but also graft cells onto it,” he said. “This is where we are going. You will (in the future) be able to have organs on the shelf. Instead of harvesting it, you can print it.”

Scientists Illuminate the Neurons of Social Attraction

Posted by in categories: biological, genetics, neuroscience, sex

The ancient impulse to procreate is necessary for survival and must be hardwired into our brains. Now scientists from the University of North Carolina School of Medicine have discovered an important clue about the neurons involved in that wiring.

Using advanced deep brain imaging techniques and optogenetics, the UNC scientists found that a small cluster of sex-hormone-sensitive neurons in the mouse hypothalamus are specialized for inducing mice to “notice” the opposite sex and trigger attraction.

This study, led by Garret D. Stuber, PhD, associate professor of psychiatry and cell biology & physiology, and Jenna A. McHenry, PhD, a postdoctoral research associate in Stuber’s lab, identified a hormone-sensitive circuit in the brain that controls social motivation in female mice.

Sciaky 3D Prints Metal Tank For Arctic Submarine

Posted by in categories: 3D printing, business, engineering

Nice.


Submarine manufacturer saves major time and cost by 3D Printing a titanium Variable Ballast tank with EBM technology from Sciaky.

The production of an Arctic Explorer submarine was nearly scuppered after the supplier of a component went out of business. To find a solution, however, International Submarine Engineering (ISE) didn’t have to dive too deep. They turned instead to additive manufacturing.

Meet Bat Bot: The First Flying Robot

Posted by in categories: drones, robotics/AI

Could we see Humanoid robots with wings someday?


Bat Bot, a lightweight flier with thin silicone wings stretched over a carbon fiber skeleton, can cruise, dive and bank turn just like its namesake, researchers report February 1 in Science Robotics, Joinfo.com reports with reference to Science News.

Disposa-drones

Posted by in categories: biotech/medical, drones

San Francisco-based research company Otherlab is developing a new concept for disposable delivery drones made of cardboard.

The project is funded by the US Defense Advanced Research Agency (DARPA), and it aims to develop drones which can be used to deliver medical supplies and other cargo to remote or hard-to-reach locations.

The drone is designed to make only an outward journey – no returns – and then be discarded. The fact that the drone only has to make a one-way trip will extend its range. The vehicle’s primary method of propulsion will be gliding.

Origami-inspired radiator from NASA could change shape to warm or cool tiny satellites

Posted by in categories: electronics, satellites

The devices we’re sending into space are getting smaller and lighter, which means there’s less room for bulky and static components. Flexibility and compactness are coming into vogue, and this prototype satellite radiator is inspired by that most compact and flexible of arts: origami.

An ordinary radiator would, of course, help dissipate heat generated by the sun or on-board electronics. But its shape and size, and therefore to a certain extent its capabilities, are set when it is manufactured.

Goddard Space Flight Center and Brigham Young University researchers are working on a radiator that can fold up or expand as needed to accelerate or slow the rate of heat dissipation as its operators see fit.

Cognitive electronic warfare: Countering threats posed by adaptive radars

Posted by in categories: information science, military, robotics/AI

A little delayed in sharing this.


Threats posed by to systems are a colossal challenge for the U.S. Navy, but a combo of advanced , intelligent algorithms, and are being developed to help warfighters detect and counter them.

Electronic warfare (EW) systems – whether on land or aboard U.S. military ships and aircraft – tap the to sense, protect, and communicate. But, when necessary, these same systems can be turned against adversaries to deny their ability to disrupt or use radio, infrared, or signals.

Whoosh! Swish! Meet Bat Bot, the new flying batlike drone

Posted by in categories: drones, nuclear energy, robotics/AI

WASHINGTON (AP) — Holy drone, Batman! Mechanical masterminds have spawned the Bat Bot, a soaring, sweeping and diving robot that may eventually fly circles around other drones.

Because it mimics the unique and more flexible way bats fly, this 3-ounce prototype could do a better and safer job getting into disaster sites and scoping out construction zones than bulky drones with spinning rotors, said the three authors of a study released Wednesday in the journal Science Robotics. For example, it would have been ideal for going inside the damaged Fukushima nuclear plant in Japan, said study co-author Seth Hutchinson, an engineering professor at the University of Illinois.

The bat robot flaps its wings for better aerial maneuvers, glides to save energy and dive bombs when needed. Eventually, the researchers hope to have it perch upside down like the real thing, but that will have to wait for the robot’s sequel.

Entire universe could be a hologram, study suggests

Posted by in categories: cosmology, holograms, quantum physics

As strange as it may sound, the universe actually may be a hologram, according to a recent study published in the journal Physical Review Letters.

Despite our knowledge of the universe, cosmologists have never been able to agree on a single unified model. This is because many current versions describe the cosmos with either general relativity or quantum theory, and neither of those work well together.

In an attempt to bridge this gap, a team of researchers from Canada, England, and the United States, argued that a holographic explanation of the universe could provide a set model, UPI reports. This is because it is able to account for irregularities in the echo of thermal energy leftover from the Big Bang, known as the cosmic microwave background.

Coordinates of more than 23,000 atoms in technologically important material mapped

Posted by in categories: bioengineering, nanotechnology, particle physics, quantum physics

Nice read.


The results demonstrate that the positions of tens of thousands of atoms can be precisely identified and then fed into quantum mechanics calculations to correlate imperfections and defects with material properties at the single-atom level. This research will be published Feb 2. in the journal Nature.

Jianwei (John) Miao, a UCLA professor of physics and astronomy and a member of UCLA’s California NanoSystems Institute, led the international team in mapping the atomic-level details of the bimetallic nanoparticle, more than a trillion of which could fit within a grain of sand.
