What does a rock climbing belay device have in common with a subsea cable installation vessel?

A cable exhibiting torsion (above) and writhing (below). Credit: SINTEF ,What does a rock climbing belay device have in common with a subsea cable installation vessel? The answer is that both can cause torsion, meaning the climbing rope or cable will start to twist. Up until now, no-one could explain why this happened. However, two enthusiastic researchers, who happen to be rock climbers, made it their business to solve the mystery. The construction of offshore wind and solar farms requires…

Ma Named MAE Chair – University of Missouri College of Engineering

Department of Mechanical and Aerospace Engineering Professor Hongbin “Bill” Ma Professor Hongbin “Bill” Ma has been named chair of the Department of Mechanical and Aerospace Engineering (MAE) by College of Engineering Interim Dean Noah Manring. Ma started his appointment Jan. 1. “Professor Ma has the experience and know-how to lead the department. I look forward to working with him as the new chair of the mechanical and aerospace engineering department,” Manring said. Ma will bring his research and teaching strengths…

Could we harness energy from black holes? A new study indicates energy can be extracted from black holes through reconnection of magnetic field lines — ScienceDaily

A remarkable prediction of Einstein’s theory of general relativity — the theory that connects space, time, and gravity — is that rotating black holes have enormous amounts of energy available to be tapped. For the last 50 years, scientists have tried to come up with methods to unleash this power. Nobel physicist Roger Penrose theorized that a particle disintegration could draw energy from a black hole; Stephen Hawking proposed that black holes could release energy through quantum mechanical emission; while…

Scientists develop high-throughput mitochondria transfer device — ScienceDaily

Scientists from the UCLA Jonsson Comprehensive Cancer Center have developed a simple, high-throughput method for transferring isolated mitochondria and their associated mitochondrial DNA into mammalian cells. This approach enables researchers to tailor a key genetic component of cells, to study and potentially treat debilitating diseases such as cancer, diabetes and metabolic disorders. A study, published today in the journal Cell Reports, describes how the new UCLA-developed device, called MitoPunch, transfers mitochondria into 100,000 or more recipient cells simultaneously, which is…

Make drones sound less annoying by factoring in humans at the design stage

Credit: Shutterstock/DmitryKalinovsky These days, almost everyone has either flown a drone or listened to the nasty whining sound they produce. Although small drones (up to 20kg) are about 40 decibels quieter than conventional civil aircraft, they produce a high pitched noise—which people tend to find very annoying. One Nasa study found that drone sounds were more annoying than those made by road vehicles. And my own research has found that the noise of drones is less preferable than that of…

Invention may get Army quadcopters to move faster

Army Researcher Dr. Jean-Paul Reddinger invents a new hinge that enables load-bearing, large, Army quadrotors to climb a few dozen feet in seconds. Credit: U.S. Army graphic Researchers believe a new hinge is the key to get load-bearing, large, Army quadrotors to climb a few dozen feet in seconds. Dr. Jean-Paul Reddinger, a research aerospace engineer with the U.S. Army Combat Capabilities Development Command, now known as DEVCOM, Army Research Laboratory, is studying how quickly a quadrotor the size of…

NASA Uses 3D Printing to Bring the Cost of Space Exploration Down to Earth

Young Industries, a leading manufacturer of custom-designed equipment for handling dry bulk materials, had been using SOLIDWORKS 3D applications for two decades. The company also used 2D CAD for critical workflows including modifying legacy drawings, creating new layouts and sketches, and developing diagrams. They knew it was time for a change when their MountainTop 2D design software experienced hardware and software failures. After a thorough evaluation of 2D design software, DraftSight rose to the top of Young Industries’ list. The…

Army looks to improve quadrotor drone performance

Credit: The Army Research Laboratory When an aircraft veers upwards too much, the decrease in lift and increase in drag may cause the vehicle to suddenly plummet. Known as a stall, this phenomenon has prompted many drone manufacturers to err on the side of extreme caution when they plan their vehicles’ autonomous flight movements. For vertical takeoff and landing tail-sitter drones, most manufacturers program the aircraft so that the vehicle body turns very slowly whenever it transitions from hover to…

Huge drone set to launch satellites in mid-air

We all have images in our mind of rocket launches from Cape Canaveral Air Force Station hurtling astronauts into space and satellites into orbit. But those launches may be a thing of the past as a new generation of drones that can do the same job cheaper, safer and better steps into play. Alabama-Based Aevum unveiled its Ravn X Autonomous Launch Vehicle Wednesday that it says is the world’s largest unmanned aircraft system. The Ravn X fleet, with aircraft at…
