The future imagined in “The Jetsons” is almost here — smart watches track our steps, Zoom connects us to the people we love, and camera drones steadily increase the views on any vlogger’s YouTube channel. The only thing we’re missing from the animated sitcom is air traffic in the form of flying cars. Although, it looks like we’re not too far from that reality, either. Consequently, robots and AR will also be commonplace.

If all of this seems too “Black Mirror” for you to process, we suggest taking a step-by-step approach. Invest in a watch that tells you how much you’ve walked but not how much you’ve slept. Until further notice, only board airplanes to fly. Instead of hiring your own Rosey the Robot housekeeper, meet with a robot every other week.

A new study finds the magnetic field generated by a tsunami can be detected a few minutes earlier than changes in sea level and could improve warnings of these giant waves.

Tsunamis generate magnetic fields as they move conductive seawater through the Earth’s magnetic field. Researchers previously predicted that the tsunami’s magnetic field would arrive before a change in sea level, but they lacked simultaneous measurements of magnetics and sea level that are necessary to demonstrate the phenomenon.

The new study provides real-world evidence for using tsunamis’ magnetic fields to predict the height of tsunami waves using data from two real events—a 2009 tsunami in Samoa and a 2010 tsunami in Chile—that have both sets of necessary data. The new study was published in AGU’s Journal of Geophysical Research: Solid Earth, which focuses on the physics and chemistry of the solid Earth.

Though innovation is often associated with Silicon Valley and high-tech start-ups, sometimes all that’s needed to make a big difference in people’s lives is a new spin on tradition, UNCTAD Deputy Secretary-General Isabelle Durant said on 2 July at the opening of a meeting in Geneva on the topic.

Mitticool, the clay refrigerator that requires no electricity, costs less than $50 and can keep food fresh for 2 to 3 days, is just one example of the power of “frugal innovation”, Ms. Durant said.

Inspiration came to the Indian inventor, Mansukhbhai Prajapati, after seeing his community suffer during the Gujarat earthquake of 2001, when a magnitude seven quake wrecked more than 8,000 villages, killing around 20,000 and leaving a million others without a home.

One of the barriers to generating electricity from wind and solar energy is their intermittent nature. A promising alternative to accommodate the fluctuations in power output during unfavorable environmental conditions are hydrogen storage systems, which use hydrogen produced from water splitting to generate clean electricity. However, these systems suffer from poor efficiency and often need to be large in size to compensate for it. This, in turn, makes for complex thermal management and a lowered energy and power density.

In a study published in Journal of Power Sources, researchers from Tokyo Tech have now proposed an alternative electric energy storage system that utilizes carbon © as an energy source instead of hydrogen. The new system, called a “carbon/air secondary battery (CASB),” consists of a solid-oxide fuel and electrolysis cell (SOFC/ECs) where carbon generated via electrolysis of carbon dioxide (CO₂), is oxidized with air to produce energy. The SOFC/ECs can be supplied with compressed liquefied CO₂ to make up the energy storage system.

“Similar to a battery, the CASB is charged using the energy generated by the renewable sources to reduce CO₂ to C. During the subsequent discharge phase, the C is oxidized to generate energy,” explains Prof. Manabu Ihara from Tokyo Tech.

Method combines quantum mechanics with machine learning to accurately predict oxide reactions at high temperatures when no experimental data is available; could be used to design clean carbon-neutral processes for steel production and metal recycling.

Extracting metals from oxides at high temperatures is essential not only for producing metals such as steel but also for recycling. Because current extraction processes are very carbon-intensive, emitting large quantities of greenhouse gases, researchers have been exploring new approaches to developing “greener” processes. This work has been especially challenging to do in the lab because it requires costly reactors. Building and running computer simulations would be an alternative, but currently there is no computational method that can accurately predict oxide reactions at high temperatures when no experimental data is available.

A Columbia Engineering team reports that they have developed a new computation technique that, through combining quantum mechanics and machine learning, can accurately predict the reduction temperature of metal oxides to their base metals. Their approach is computationally as efficient as conventional calculations at zero temperature and, in their tests, more accurate than computationally demanding simulations of temperature effects using quantum chemistry methods. The study, led by Alexander Urban, assistant professor of chemical engineering, was published on December 1, 2021 by Nature Communications.

If anything, the development is yet another indication of the threat actor’s capacity to continually “innovate and identify new techniques and tradecraft to maintain persistent access to victim environments, hinder detection, and confuse attribution efforts,” while also highlighting the “effectiveness of leveraging third parties and trusted vendor relationships to carry out nefarious operations.”

Microsoft had previously dubbed Nobelium as “skillful and methodic operators who follow operations security (OpSec) best practices.”

Ever since the SolarWinds incident came to light, the APT group has been connected to a string of attacks aimed at think tanks, businesses, and government entities around the globe, even as an ever-expanding malware toolbox has been put to use with the goal of establishing a foothold in the attacked system and downloading other malicious components.

GOING TO BED AFTER THIS SPECIFIC TIME DAMAGES METABOLIC HEALTH – STUDY

In a study published last week in Diabetologia, both disturbed sleep patterns and going to sleep after midnight were correlated to a less-than-optimal postprandial response. Specifically, poor sleep affected the body’s ability to rope glucose (sugar) levels back to normal after a meal.

The coldest continent on Earth used to be as warm as Italy. Here’s how we know.

A polar expedition drilled into the seafloor and unearthed 90-million-year-old tree roots.

A floating, robotic film designed at UC Riverside could be trained to hoover oil spills at sea or remove contaminants from drinking water.

Powered by light and fueled by water, the film could be deployed indefinitely to clean remote areas where recharging by other means would prove difficult.

“Our motivation was to make soft robots sustainable and able to adapt on their own to changes in the environment. If sunlight is used for power, this machine is sustainable, and won’t require additional energy sources,” said UCR chemist Zhiwei Li. “The film is also re-usable.”
