A transportation company is betting its sleek new hydrogen-powered electric flying vehicles will someday serve as taxis, cargo carriers and ambulances of the sky, but experts say they will have to clear a number of regulatory hurdles before being approved for takeoff years in the future.

Research reveals role of fat storage cells in anti-obesity intervention
New research from a team at the Marshall University Joan C. Edwards School of Medicine establishes a role of adipocyte Na/K-ATPase signaling in worsening obesity and its companion diseases, including neurodegeneration and non-alcoholic steatohepatitis (NASH), that was enhanced by specific targeting of NaKtide, an antagonist of Na/K-ATPase signaling, to the adipocyte.

New algorithm may help people store more pictures, share videos faster
The world produces about 2.5 quintillion bytes of data every day. Storing and transferring all of this enormous—and constantly growing—number of images, videos, Tweets, and other forms of data is becoming a significant challenge, one that threatens to undermine the growth of the internet and thwart the introduction of new technologies, such as the Internet of Things.

Climate change is already affecting global food production—unequally
The world's top 10 crops— barley, cassava, maize, oil palm, rapeseed, rice, sorghum, soybean, sugarcane and wheat—supply a combined 83 percent of all calories produced on cropland. Yields have long been projected to decrease in future climate conditions. Now, new research shows climate change has already affected production of these key energy sources—and some regions and countries are faring far worse than others.

Understanding identity in online worlds
For Rosa Mikeal Martey, professor in Journalism and Media Communication, the relationship between identity in the offline world and identity construction in a virtual world has always been of research interest. For her dissertation, Martey studied gender identity and perception in online job applications. Her current research involves understanding how social norms develop in digital spaces. "I'm interested in the way people interact with, use, and respond to technology as they perform and craft those identities," she says. "Identity is a fluid category that emerges in different spaces and is influenced by the space itself."

More opioids given than prescribed in emergency department
(HealthDay)—The rate of emergency department visits with opioids only given during the visit is higher than the rate for visits with opioids only prescribed at discharge and for visits with opioids given and prescribed, according to a May data brief published by the U.S. Centers for Disease Control and Prevention National Center for Health Statistics.

Three ways to travel at (nearly) the speed of light
One hundred years ago today, on May 29, 1919, measurements of a solar eclipse offered verification for Einstein's theory of general relativity. Even before that, Einstein had developed the theory of special relativity, which revolutionized the way we understand light. To this day, it provides guidance on understanding how particles move through space—a key area of research to keep spacecraft and astronauts safe from radiation.

Maestro: a new attack that orchestrates malicious flows with BGP
Researchers at the University of Tennessee have recently identified the Maestro attack, a new link flooding attack (LFA) that leverages plane traffic control engineering techniques to concentrate botnet-sourced distributed denial of service (DDos) flows on transit links. In their paper, recently published on arXiv, the researchers outlined this type attack, tried to understand its scope and presented effective mitigations for network operators who wish to insulate themselves from it.

U.S. Postal Service mail, packages are headed to Dallas by self-driving truck
Before letters end up in your mailbox and packages land on your doorstep, many travel hundreds or thousands of miles in the back of a truck. Now, the United States Postal Service is testing what it would take to shuttle that cargo without a driver in the front seat.

Making structural changes to antibody has potential for reducing cancer tumours
Guided by "blueprints" produced at the Canadian Light Source (CLS) at the University of Saskatchewan, a group of scientists from academia and industry made structural changes to an antibody that is now showing a lot of potential for reducing cancer tumours.

PULP Dronet: A 27-gram nano-UAV inspired by insects
Researchers at ETH Zürich and the University of Bologna have recently created PULP Dronet, a 27-gram nano-size unmanned aerial vehicle (UAV) with a deep learning-based visual navigation engine. Their mini-drone, presented in a paper pre-published on arXiv, can run aboard an end-to-end, closed-loop visual pipeline for autonomous navigation powered by a state-of-the-art deep learning algorithm.

A prosthetic foot that tackles tough terrain
Taking on a hiking trail or a cobblestone street with a prosthetic leg is a risky proposition—it's possible, but even in relatively easy terrain, people who use prostheses to walk are more likely to fall than others. Now, Stanford University mechanical engineers have developed a more stable prosthetic leg—and a better way of designing them—that could make challenging terrain more manageable for people who have lost a lower leg.
