When you think of diamonds, rings and anniversaries generally come to mind. But one day, the first thing that will come to mind may be bone surgery. By carefully designing modified diamonds at the nano-scale level, a Missouri University of Science and Technology researcher hopes to create multifunctional diamond-based materials for applications ranging from advanced composites to drug delivery platforms and biomedical imaging agents.
Dr. Vadym Mochalin, an associate professor of chemistry and materials science and engineering at Missouri S&T, is characterizing and modifying 5-nanometer nanodiamond particles produced from expired military grade explosives so that they can be developed to perform specific tasks. His current research studies their use as a filler in various types of composites.
Mochalin hopes to develop a way to uniformly incorporate the nanodiamonds and form strong chemical bonds between them to help design composite structures that can be used in medical applications, oil drilling bits, polishing and lubricating compositions, and even energy storage systems. Nanodiamonds are the ideal choice for such applications because they are mechanically strong, chemically stable and non-toxic. They can also form bonds with many other materials due to their tailorable surface chemistry.

On the fifty-fifth anniversary of Yuri Gagarin’s great leap into space, April 12, 2016, Yuri Milner was joined by Stephen Hawking at New York’s One World Observatory to announce Breakthrough Starshot, which will lay the foundations for humanity’s next great leap: to the stars. It was also announced that Mark Zuckerberg joined the board of the initiative.
Breakthrough Starshot is a $100 million research and development program, aiming to establish proof of concept for a ‘nanocraft’ – a fully functional space probe at gram-scale weight – driven by a light beam. A spacecraft like this, equipped with a lightsail, has the potential to reach twenty percent of the speed of light – or 100 million miles an hour. At that speed, it could reach Alpha Centauri, our nearest star system, in around 20 years. Using the fastest conventional rocket propulsion system available, the same journey would take tens of thousands of years.
This new scientific initiative is committed to international collaboration, open access and open data. It aims to represent all of humanity as one world, stepping out into the galaxy within a generation.
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.”

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.

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.
ISE had originally planned to produce the titanium Variable Ballast (VB) tank with traditional manufacturing methods. Their key supplier was an overseas titanium forging facility that previously produced propellant tanks for the Russian space program. But then the supplier went bankrupt.
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.
Such a maneuverable machine could one day soar up the towering structures of a construction site, flying in and out of steel beams to help keep track of a building’s progress, study coauthor Seth Hutchinson, a roboticist at the University of Illinois at Urbana-Champaign, said in a news briefing January 31.

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.

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.
