A drone has successfully inspected a 19.4 meter high oil tank onboard a Floating Production, Storage and Offloading vessel. The video shot by the drone was interpreted in real-time by an algorithm to detect cracks in the structure.

Scout Drone Inspection and class society DNV GL have been working together to develop an autonomous drone system to overcome the common challenges of tank inspections. For the customer, costs can run into hundreds of thousands of dollars as the tank is taken out of service for days to ventilate and construct scaffolding. The tanks are also tough work environments, with surveyors often having to climb or raft into hard to reach corners. Using a drone in combination with an algorithm to gather and analyse video footage can significantly reduce survey times and staging costs, while at the same time improving surveyor safety.

PNNL quantum algorithm theorist and developer Nathan Wiebe is applying ideas from data science and gaming hacks to quantum computing.

Everyone working on quantum computers knows the devices are error prone. The basic unit of quantum programming – the quantum gate – fails about once every hundred operations. And that error rate is too high.

While hardware developers and programming analysts are fretting over failure rates, PNNL’s Nathan Wiebe is forging ahead writing code that he is confident will run on quantum computers when they are ready. In his joint appointment role as a professor of physics at the University of Washington, Wiebe is training the next generation of quantum computing theorists and programmers.

Washington State University researchers have made a key advance in solid oxide fuel cells (SOFCs) that could make the highly energy-efficient and low-polluting technology a more viable alternative to gasoline combustion engines for powering cars.

Led by Ph.D. graduate Qusay Bkour and Professor Su Ha in the Gene and Linda Voiland School of Chemical Engineering and Bioengineering, the researchers have developed a unique and inexpensive nanoparticle catalyst that allows the fuel cell to convert logistic liquid fuels such as gasoline to electricity without stalling out during the electrochemical process. The research, featured in the journal, Applied Catalysis B: Environmental, could result in highly efficient gasoline-powered cars that produce low carbon dioxide emissions that contribute to global warming.

“People are very concerned about energy, the environment, and global warming,” said Bkour. “I’m very excited because we can have a solution to the energy problem that also reduces the emissions that cause global warming.”

The search for renewable energy sources, which include wind, solar, hydroelectric dams, geothermal, and biomass, has preoccupied scientists and policymakers alike, due to their enormous potential in the fight against climate change. A new Tel Aviv University study finds that water vapor in the atmosphere may serve as a potential renewable energy source in the future.

The research, led by Prof. Colin Price in collaboration with Prof. Hadas Saaroni and doctoral student Judi Lax, all of TAU’s Porter School of the Environment and Earth Sciences, is based on the discovery that electricity materializes in the interaction between water molecules and metal surfaces. It was published in Scientific Reports on May 6, 2020.

“We sought to capitalize on a naturally occurring phenomenon: electricity from water,” explains Prof. Price. “Electricity in thunderstorms is generated only by water in its different phases— water vapor, water droplets, and ice. Twenty minutes of cloud development is how we get from water droplets to huge electric discharges—lightning—some half a mile in length.”

On August 2nd, the SpaceX crew dragon that launched on May 30th returned to Earth with the two NASA astronauts it brought to the ISS. With the first American space launch complete, the US has now advanced tremendously in its manned spaceflight capabilities.

Mushroom leather is the latest alternative to animal leather.

Self-healing materials are so widespread that clothes lines and tech companies are already applying them to different products.

Now, a research team at the University of California, Riverside, has developed a new type of self-healing material that is conductive of electricity, highly elastic and almost entirely transparent. The lead researcher has revealed that he drew inspiration from Marvel’s Wolverine character.

Our brains have an upper limit on how much they can process at once due to a constant but limited energy supply, according to a new UCL study using a brain imaging method that measures cellular metabolism.

The study, published in the Journal of Neuroscience, found that paying attention can change how the brain allocates its limited energy; as the brain uses more energy in processing what we attend to, less energy is supplied to processing outside our attention focus.

Explaining the research, senior author Professor Nilli Lavie (UCL Institute of Cognitive Neuroscience) said: It takes a lot of energy to run the human brain. We know that the brain constantly uses around 20% of our metabolic energy, even while we rest our mind, and yet it’s widely believed that this constant but limited supply of energy does not increase when there is more for our mind to process.

Well, they don’t.

Thousands are currently engaged in solving the problem of death. Maybe they’ll succeed, and out of sheer boredom I’ll reread this sentence when I’m 900 years old, reflecting fondly on the first wasted century of my life. In the meantime, billions are going to die—some from disease, some in freak accidents, and a substantial number from what we generally call “old age.” That last sounds like a pleasant way to go, comparatively—a peaceful winding-down. But what exactly does it look like? What does it really mean to die from old age? For this week’s Giz Asks, we reached out to a number of experts to find out.
