Would you ride in a Hyperloop?

This week's Question: MIT recently unveiled its prototype design for SpaceX founder Elon Musk's Hyperloop, a high-speed ground transport system that could theoretically send passengers from Los Angeles to San Francisco in half an hour. The university researchers will test their small prototype pod at SpaceX’s Hyperloop Test Track this summer. SpaceX initially envisioned using a cushion of air to transport the Hyperloop pod. MIT’s team, however, employs a magnetic levitation system, which incorporates two arrays of 20 neodymium magnets to keep the pod levitating at 15 mm. While MIT’s design is not big enough to fit a human body, the team told BBC News that scaling up the size would be straightforward once testing of the prototype pod is completed. The team still needs to address the development of turning and further test the braking system. What do you think? Would you ride in a Hyperloop?

NASA and FAA Demonstrate Wireless Communication with Aircraft

For the first time ever, a team of engineers at NASA’s Glenn Research Center conveyed aviation data -- including route options and weather information -- to an airplane over a wireless communication system for aircraft on the ground. The demonstration, conducted with the Federal Aviation Administration demonstrated two technologies that could change airport operations worldwide.

Royal Navy Uses Pilotless Aircraft to Navigate Through Ice

A tiny pilotless aircraft, built by the University of Southampton, launched from the Royal Navy’s ice patrol ship HMS Protector for the first time to assist with navigating through the Antarctic. The 3D-printed aircraft, along with a quadcopter, scouted the way for the survey ship so she could find her way through the thick ice of frozen seas. It’s the first time the Royal Navy has used unmanned aerial vehicles in this part of the world.

Camouflage Really Does Reduce Chances of Being Eaten

A ground-breaking study not only confirms the assumption that camouflage protects animals from the clutches of predators, but it also offers insights into the most important aspects of camouflage. The research by scientists from the Universities of Exeter and Cambridge investigated the camouflage of ground-nesting birds in Zambia, using sophisticated digital imaging to demonstrate how they would appear from the perspective of a predator. Martin Stevens from Exeter University who, along with Claire Spottiswoode from the University of Cambridge, co-led the project said: "Despite such a long history of research, ours is the first study to directly show how the degree of camouflage an individual has, to the eyes of its predators, directly affects the likelihood of it being seen and eaten in the wild." The team studied a variety of ground-nesting birds, whose eggs would stay in a fixed location throughout the month-long period needed for incubation. This allowed the scientists to accurately compare both the adult birds, and their eggs, to their chosen backgrounds, as well as monitor which nests had been found by predators such as banded mongooses, birds, and vervet monkeys. The team used specially calibrated digital cameras and computer models of animal vision to view the nests as the predators might see them. This ranged from the sophisticated color vision of birds, which can see ultraviolet wavelengths, to the relatively poor color vision of mongooses, which only see blues and yellows. The research shows that the eggs of species that flee the nest as predators approach, such as plovers and coursers, are more likely to survive to hatching if they match the background more closely when exposed to view by their fleeing parent. In nightjars, however, which conceal their eggs by remaining motionless over them when predators approach, it was the appearance of the adults that was most important for their survival: nightjars that match the background pattern are more likely to save their eggs from being eaten.

Scientists Watch Bacterial Sensor Respond to Light

A number of important biological processes, such as photosynthesis and vision, depend on light. But it’s hard to capture responses of biomolecules to light because they happen almost instantaneously. Now, researchers have made a giant leap forward in taking snapshots of these ultrafast reactions in a bacterial light sensor. Using the world’s most powerful X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory, they were able to see atomic motions as fast as 100 quadrillionths of a second – 1,000 times faster than ever before. “We’re the first to succeed in taking real-time snapshots of an ultrafast structure transition in a protein, in which a molecule excited by light relaxes by rearranging its structure in what is known as trans-to-cis isomerization,” says the study’s principal investigator, Marius Schmidt from the University of Wisconsin, Milwaukee. The technique could benefit studies of light-driven, ultrafast atomic motions. For example, it could reveal: How visual pigments in the human eye respond to light, and how absorbing too much of it damages them. How photosynthetic organisms turn light into chemical energy – a process that could serve as a model for the development of new energy technologies. How atomic structures respond to light pulses of different shape and duration – an important first step toward controlling chemical reactions with light. “The new data show for the first time how the bacterial sensor reacts immediately after it absorbs light,” says Andy Aquila, a researcher at SLAC’s Linac Coherent Light Source, a DOE Office of Science User Facility. “The initial response, which is almost instantaneous, is absolutely crucial because it creates a ripple effect in the protein, setting the stage for its biological function. Only LCLS’s X-ray pulses are bright enough and short enough to capture biological processes on this ultrafast timescale.”
