A major challenge for producers of electricity from solar panels and wind turbines is akin to capturing lightning in a bottle. Both solar and wind increasingly generate electricity amid little demand, when market prices are too low to cover costs. At noon on sunny days, for example, wholesale power prices in areas with high quantities of solar and wind occasionally fall below zero.

Some renewable energy producers store their excess electricity as green hydrogen, using the electricity to produce hydrogen from water—labeled “green” because the process emits no carbon dioxide. Used to create fuels, fertilizer, and other chemicals, the global hydrogen market is about $125 billion, and it’s growing briskly in part due to increased interest in hydrogen as a fuel for buses, trucks, and even ships. The problem is that producing hydrogen with electricity remains fairly expensive, so it’s only profitable to sell at the higher prices paid by lower-volume customers.

But now, researchers at Stanford University and at the University of Mannheim in Germany have found a possible solution: integrated reversible power-to-gas systems that can easily convert hydrogen back to electricity when power prices spike higher.

Safety avionics specialist Iris Automation has made a meteorological enhancement to its Casia G ground-based surveillance system with the integration of TruWeather Solutions sensors and services – a move aiming to add climate security to the company’s aerial detect-and-avoid protection.

Addition of a precision weather utility was a natural step in Iris Automation’s wider objective of ensuring flight safety of, and between, crewed aircraft and drones The company says local micro weather and low-altitude atmospheric conditions often differ considerably from those at higher levels. That differential creates a larger degree of weather uncertainty for aerial service providers, who weigh safety factors heavily into whether they make flights as planned or not.

Elon Musk talks to Chris Anderson, head and curator of the TED media organisation, about the challenges facing humanity in the coming decades – and why we should be more optimistic.

They discuss climate change, clean energy, electric vehicles, the rise of AI and robotics, brain-computer interfaces, self-driving cars, the revolutionary potential of reusable rockets and the forthcoming missions to Mars, as well as the other projects he is working on.

Highly energetic particles called muons are ever present in the atmosphere and pass through even massive objects with ease. Sensitive detectors installed along the Tokyo Bay tunnel measure muons passing through the sea above them. This allows for changes in the volume of water above the tunnel to be calculated. For the first time, this method was used to accurately detect a mild tsunami following a typhoon in 2021.

In the time it takes you to read this sentence, approximately 100,000 muon particles will have passed through your body. But don’t worry, muons pass through ordinary matter harmlessly, and they can be extremely useful too. Professor Hiroyuki Tanaka from Muographix at the University of Tokyo has made his career out of exploring applications for muons. He’s used them to see inside volcanoes and even detect evidence of ancient earthquakes. Recently, Tanaka and his international team of researchers have turned their focus to meteorological phenomena, in particular, tsunamis.

In September 2021, a typhoon approached Japan from the south. As it neared the land it brought with it ocean swells, tsunamis. On this occasion these were quite mild, but throughout history, tsunamis have caused great damage to many coastal areas around Japan. As the huge swell moved into Tokyo Bay, something happened on a microscopic level that’s almost imperceptible. Atmospheric muon particles, generated by cosmic rays from deep space, were ever so slightly more scattered by the extra volume of water than they would be otherwise. This means the quantity of muons passing through Tokyo Bay varied as the ocean swelled.

A new study published in Nature reveals the likely impacts of climate change on cacti by mid-century.

Way back in 2015, Apple released its very first app in the Google Play Store. It was called Move to iOS, and it helped people switch from Google’s platform to Apple’s. Turnabout is fair play, and Google has finally made its own switching app. With the predictable name “Switch To Android,” the app helps iPhone owners export their data for use on an Android phone. The app rolled out today in several markets, including the US, but it might be hard to find.

The current mobile dichotomy has been in place for over a decade at this point. Upstarts like Palm and Windows Phone tried and failed to create a third platform, but instead we’ve all become more entrenched with Android and iOS. After years and years using one platform, it can be imposing to move it someplace else. Apps like Apple’s Move to iOS and the new Switch To Android can make it a bit easier by automating the process, or at least pointing you to the right settings.

After installing the Switch To Android app on an iPhone, you’ll have the option to grab the basics like your contacts, calendar events, photos, and videos. Most of this data should plug into Google’s ecosystem without issue. You might notice some strange errors in contact data, but the app connects to Google Photos to salvage all your iCloud media. This all happens wirelessly, so you won’t have to worry about finding a cable to connect your Android phone’s USB-C port to the aging Lightning port on even the latest iPhones.

With this month’s release of the F-150 Lightning, Ford hopes to electrify new and traditional truck buyers alike, and—eventually—to replace its industry-defining gas-powered line.

… along with new, unfamiliar — and often poorly understood — risks.

Technology and business risks morph with changes in technology and how it is delivered. While cloud services are often considered more dependable, businesses face new risks with SaaS and public cloud — risks that are unfamiliar or not completely understood. People’s eyes pop open and ears perk up when they witness prolonged outage events such as the current issue with Atlassian. Suddenly, SaaS dependencies and resilience issues become relevant, as a business can’t access its favorite SaaS tool. The unique risk of using SaaS is that you don’t have control over the application or the tool and cannot reimplement yourself. It is also important to understand the cascading risks, as some of the well-known SaaS services are hosted on a leading hyperscaler’s infrastructure. You need to analyze the business impact of SaaS and cloud services outages just like for any other technology in your portfolio.

Trust but verify vendor claims about service-level agreements supporting operations and resilience plans. To ensure that your SaaS providers deliver on their own promises:

The system developed in Milano is robust and it also has the potential to process information encoded in different coupled systems, including far and enormous galaxies. Thanks to these new results, it is now possible to simulate in the lab complex coupled systems, with order altered by stable defects, difficult to be reproduced otherwise since involving ginormous scale, like galaxies, or part of extreme hydrodynamic systems.

Water whirlpools, smoke rings, violent tornados and spiral galaxies are all examples of twists in fluids, although very different each other. Analogous twists, but in the realm of light, have been created by the research group coordinated by Antonio Ambrosio at the IIT-Istituto Italiano di Tecnologia (Italian Institute of Technology), in Milano (Italy). The results, published in the journal Nature Photonics, show the realization of 100 light vortices, coupled to form an ordered structure, a light crystal.

Mutual interaction of light and nanostructured materials is the focus of the research of Antonio Ambrosio, Principal Investigator of the research line Vectorial Nano-imaging at IIT in Milano and grantee of the ERC Consolidator project “METAmorphoses.”
