Scientists have developed a new solar-powered system to convert saltwater into fresh drinking water which they say could help reduce dangerous the risk of waterborne diseases like cholera.

Via tests in rural communities, they showed that the process is more than 20% cheaper than traditional methods and can be deployed in rural locations around the globe.

Building on existing processes that convert saline groundwater to freshwater, the researchers from King’s College London, in collaboration with MIT and the Helmholtz Institute for Renewable Energy Systems, created a new system that produced consistent levels of water using solar power, and reported it in a paper published recently in Nature Water.

It works through a process called electrodialysis which separates the salt using a set of specialized membranes that channel salt ions into a stream of brine, leaving the water fresh and drinkable. By flexibly adjusting the voltage and the rate at which salt water flowed through the system, the researchers developed a system that adjusts to variable sunshine while not compromising on the amount of fresh drinking water produced.

Using data first gathered in the village of Chelleru near Hyderabad in India, and then recreating these conditions of the village in New Mexico, the team successfully converted up to 10 cubic meters, or several bathtubs worth of fresh drinking water. This was enough for 3,000 people a day with the process continuing to run regardless of variable solar power caused by cloud coverage and rain.

[Note: Not sure what metric they're using to calculate daily water needs here. Presumably this is drinking water only.]

Dr. Wei He from the Department of Engineering at King’s College London believes the new technology could bring massive benefits to rural communities, not only increasing the supply of drinking water but also bringing health benefits.

“By offering a cheap, eco-friendly alternative that can be operated off the grid, our technology enables communities to tap into alternative water sources (such as deep aquifers or saline water) to address water scarcity and contamination in traditional water supplies,” said He.

“This technology can expand water sources available to communities beyond traditional ones and by providing water from uncontaminated saline sources, may help combat water scarcity or unexpected emergencies when conventional water supplies are disrupted, for example like the recent cholera outbreaks in Zambia.”

In the global rural population, 1.6 billion people face water scarcity, many of whom are reliant on stressed reserves of groundwater lying beneath the Earth’s surface.

However, worldwide 56% of groundwater is saline and unsuitable for consumption. This issue is particularly prevalent in India, where 60% of the land harbors undrinkable saline water. Consequently, there is a pressing need for efficient desalination methods to create fresh drinking water cheaply, and at scale.

Traditional desalination technology has relied either on costly batteries in off-grid systems or a grid system to supply the energy necessary to remove salt from the water. In developing countries’ rural areas, however, grid infrastructure can be unreliable and is largely reliant on fossil fuels...

“By removing the need for a grid system entirely and cutting reliance on battery tech by 92%, our system can provide reliable access to safe drinking water, entirely emission-free, onsite, and at a discount of roughly 22% to the people who need it compared to traditional methods,” He said.

The system also has the potential to be used outside of developing areas, particularly in agriculture where climate change is leading to unstable reserves of fresh water for irrigation.

The team plans to scale up the availability of the technology across India through collaboration with local partners. Beyond this, a team from MIT also plans to create a start-up to commercialize and fund the technology.

“While the US and UK have more stable, diversified grids than most countries, they still rely on fossil fuels. By removing fossil fuels from the equation for energy-hungry sectors like agriculture, we can help accelerate the transition to Net Zero,” He said.

Researchers present new diagnostic tool for laser-plasma accelerator using metal foil as 3D scanner

Laser-plasma accelerators take up less space than conventional facilities, which are sometimes kilometers long. Such compact particle sources can accelerate electron bunches efficiently, enabling X-ray lasers that fit in the basement of a university institute. But there are a few challenges to be met: in order to produce UV or X-ray light, the electron bunches generated by a laser-plasma accelerator must be very finely bundled and have defined properties. To date, it has been difficult to even measure these bunches precisely. Now, a team at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has developed a novel measuring method that should help to drive the development of laser-plasma acceleration.

A trio of physicists and oceanologists, two with the University of Cologne's Institute of Geophysics and Meteorology and the third with the GEOMAR Helmholtz Center for Ocean Research Kiel, all in Germany, has found via the CESM1 climate model that an extreme El Niño tipping point could be reached in the coming decades under current emissions. The study by Tobias Bayr, Stephanie Fiedler and Joke Lübbecke is published in Geophysical Research Letters. The El Niño‐Southern Oscillation (ENSO) is a climate phenomenon in which heat released in parts of the ocean into the atmosphere results in more rainfall in places like the western coast of North and South America and droughts in places like Canada and Africa. Over the past several years, weather watchers have noticed that ENSO events have become more extreme. Prior research has shown that such extreme events used to occur approximately eight or nine times per century. Some in the field have suggested that rising global temperatures could make them happen more often.

Creating a low-cost ‘battery-like’ desalination technology removes the reliance on battery technology for using intermittent solar energy in off-grid applications, enabling affordability to rural communities in developing countries like India.

“By removing the need for a grid system entirely and cutting reliance on battery tech by 92%, our system can provide reliable access to safe drinking water, entirely emission-free, onsite, and at a discount of roughly 22% to the people who need it compared to traditional methods,” He said.

“The next step for us is to apply this low-cost technology to other sectors, including wastewater treatment, and producing alkaline to make the ocean more alkaline to help it absorb more CO2 from the atmosphere. By taking this approach not only can we decarbonize agriculture, but wider environmental and climate benefits as well.”

This story originally appeared in Hakai Magazine and is part of the Climate Desk collaboration.

In the Fram Strait off Greenland’s west coast, Véronique Merten encountered the foot soldiers of an invasion.

Merten was studying the region’s biodiversity using environmental DNA, a method that allows scientists to figure out which species are living nearby by sampling the tiny pieces of genetic material they shed, like scales, skin, and poop. And here, in a stretch of the Arctic Ocean 400 kilometers north of where they’d ever been seen before: capelin.

And they were everywhere.

The small baitfish found in the northern Atlantic and Pacific Oceans is an ardent colonizer. Whenever the ocean conditions change, it’s really easy for capelin to expand their range, says Merten, a marine ecologist at the GEOMAR Helmholtz Centre for Ocean Research Kiel in Germany.

It is difficult to estimate an animal’s abundance based solely on the amount of its DNA in the water. Yet in Merten’s samples, capelin was the most frequently encountered species—far more than typical Arctic fish like Greenland halibut and Arctic skate. To Merten, the evidence of so many capelin so far north is a bold sign of a worrying Arctic phenomenon: Atlantification.

The Arctic Ocean is warming quickly—the Fram Strait is nearly 2 °C warmer than it was in 1900. But Atlantification is about more than rising temperatures: it’s a process that is reshaping the physical and chemical conditions of the Arctic Ocean.

Because of the oceans’ global circulation patterns, water routinely flows from the Atlantic into the Arctic. This exchange mostly occurs in deeper water, with currents carrying warm and relatively salty Atlantic water north. This warm Atlantic water, however, doesn’t mix well with the Arctic’s surface water, which is relatively cool and fresh. Fresher water is less dense than saltier water, so the Arctic water tends to float on top, trapping the saltier Atlantic water deep below the ocean’s surface.

As sea ice disappears, however, the surface of the Arctic Ocean is heating up. The barrier between the layers is degrading and Atlantic water is mixing more easily into the upper layer. This is kicking off a feedback loop, where warmer surface water melts more sea ice, further exposing the ocean’s surface to sunlight, which heats the water, melts the ice, and allows Atlantic and Arctic water to blend even more. That’s Atlantification: the transformation of the Arctic Ocean from colder, fresher, and ice-capped to warmer, saltier, and increasingly ice-free.

Merten’s discovery of abundant capelin in the Fram Strait—as well as the DNA she found from other Atlantic species, like tuna and cock-eyed squid, far outside their typical range—is further proof of just how quickly Atlantification is playing out. And its consequences could be enormous.

In the Barents Sea off Russia, for example, a long-term study presents a grim picture of how Atlantification can disrupt Arctic ecosystems. As the Barents Sea has grown warmer and saltier, Atlantic species have been “moving in and taking over,” says Maria Fossheim, a fisheries ecologist with the Institute of Marine Research in Norway who led that study.

Fish communities in the Barents Sea, Fossheim says, have shifted north 160 kilometers in just nine years—“three or four times the pace that [previous studies] had foreseen.” By the end of her study, in 2012, Fossheim found that Atlantic species had expanded throughout the Barents Sea, while Arctic species were mostly pushed out.

Merten’s findings suggest the Fram Strait may be heading in a similar direction. Because this study is the first to examine the diversity of fish in the Fram Strait, however, it is unclear how recent these changes really are. “We need these baselines,” Merten says. “It could be that [capelin] already occurred there years ago, but no one ever checked.”

Either way, they’re there now. The question is: what will show up next?

Guest Post from John Martin Rare Book Room

At Hardin Library of Health Sciences

DU VERNEY, JOSEPH (1648-1730). A treatise of the organ of hearing: containing the structure, the uses, and the diseases of all the parts of the ear. 1737.

Hi, my name is Carlisle Isley, and I am a University of Iowa School of Library and Information Science practicum student working in the John Martin Rare Book Room this fall.

I'm introducing you to this book because I have always been fascinated with how the ear, nose, and throat, seemingly small parts of the human body, are connected and can impact our daily quality of life. Interestingly enough, we can thank Sam Baker, a bookseller from the 1700s with a bookshop in London, for A treatise…

Baker commissioned Du Verney's work to sell in his shop down the street from the Angel and Crown ale house in Covent Garden. Baker eventually transformed his bookshop into an auction house for books and manuscripts. Upon his death, he bequeathed his share of the auction house to his nephew, John Sotheby, who would lend his name to the now world-famous Sotheby's auction house.

Joseph Du Verney was an anatomical lecturer and dissection demonstrator at Jardin Du Roi, an early medical plant garden. During the reign of King Louis XIV, theatrical anatomy was performed in public spaces, but bodies could be hard to come by. Body snatching and grave robbing were common. Society was not yet comfortable with donating bodies to science.

It was common to have amphitheaters where students could observe dissections, and Du Verney, with his "dramatic, rhetorical and anatomical skills," drew crowds of people. Du Verney conducted lectures and dissections for the Paris Academy of Science, including for the heir apparent to the French throne and royal courtiers. He also lectured to medical students at the Hôtel-Dieu hospital.

Du Verney corrected beliefs that the Eustachian tube was an avenue for breathing or hearing by showing it was a channel through which air is renewed to the tympanic cavity. He explained the mechanism of bone conduction and gave an accurate account of the bony labyrinth. He greatly advanced knowledge in the physiology of hearing with his theory of hearing and communication. His theories helped inform the work of the 19th-century biophysicist and inventor Herman Ludwig Ferdinand Von Helmholtz, who was the first to measure the speed of a nerve impulse.

Prior to this book joining the John Martin Rare Book Room, it circulated in the main collection as part of the Hardin Library. During its time in the Hardin Collection, the book was heavily used and at some point, one illustration "went missing." When paging through the book, one will notice a photocopied page was inserted to replace the missing illustration. More than likely, library staff realized the illustration was missing and contacted another institution to request a photocopy from their copy of the text.

Automatische Spracherkennung und -übersetzung: Schnelleres Arbeiten und Lernen

Karlsruhe, 15.08.2024. Automatische Spracherkennungssysteme wie der Lecture Translator des Karlsruher Instituts für Technologie (KIT) können das Gesprochene in Vorträgen in Echtzeit in einen Text in mehreren Sprachen umwandeln. Damit verbessern solche Systeme den Zugang zu Informationen für Studierende mit Behinderungen und ausländische Studierende. Nun haben Forschende des KIT den Lecture Translator um neue Funktionen erweitert. Automatische Erkennung des Gesprochenen in mehreren Sprachen gleichzeitig, Textsegmentierung und Titelgenerierung in Echtzeit, Zusammenfassungen und Verlinkungen zu Fachbegriffen und Abfragen des Gehörten vereinfachen nun das Verstehen und effiziente Aufarbeiten von Vorlesungen.

„Mit der automatischen Simultanübersetzung des Lecture Translators haben wir gesprochene Vorträge einem internationalen Publikum nähergebracht. Dieses macht aber in der Regel nur 15 Prozent der Zuhörerschaft aus. Mit den neuen KI-Werkzeugen wollen wir nicht nur Sprach-, sondern auch Verständnisbarrieren abbauen“, sagt Alexander Waibel, Professor für Informatik am KIT. „Oft sind automatisch transkribierte Texte von gesprochener Sprache schwer zu lesen, da sie zu schnell fortlaufend ohne Absätze und Zwischenüberschriften als langer Text erscheinen – eben genau so, wie der Vortrag oder die Vorlesung mündlich vorgetragen wurde“. Auch die Aufarbeitung der Vorlesung sei mühsam, da man die Vorlesung nach Verständnislücken durchsuchen müsse, so Waibel. Bessere Übersicht in Dokumenten Die Weiterentwicklung des Lecture Translators schafft hier Abhilfe. Die Forschenden haben mehrere neue automatische Funktionen wie „Smart Chaptering“, Summarization“, „Q&A“ oder „Auto-Links“ entwickelt. Dabei verwandelt eine neuartige Künstliche Intelligenz (KI), die automatisch die Sprache erkennt, den gesprochenen Text in ein Transkript in mehreren Sprachen und identifiziert automatisch Absätze, Kapitelüberschriften sowie wichtige Kernpunkte. Darüber hinaus erstellt sie eine akustische Wiedergabe, bei der Nutzerinnen und Nutzer eine von 18 Sprachen auswählen können. Außerdem zeigt das Programm automatisch Links als Querverweise zu relevanten Quellen in Vorlesungsskripten oder Wikipedia an, mit deren Hilfe die Studierenden die Vorlesung besser aufarbeiten können. „Mit unseren neuen KI-Modellen können Gespräche und Vorlesungen besser strukturiert und sogar Videos in leicht navigierbare Kapitel eingeteilt werden“, so Waibel. Somit sei ein besseres Verständnis nicht nur während, sondern auch nach der Vorlesung möglich. Lecture Translator übersetzt in 18 Sprachen Die Arbeiten hat das Forschungsteam in den Lecture Translator integriert, mit dem am KIT Vorlesungen in Echtzeit automatisch transkribiert werden. Kapiteleinteilung, Titelgenerierung, Absatzgestaltung, Zusammenfassungen mit Verlinkungen – auch jeweils online und offline anwendbar – erweitern nun den Service des Lecture Translators und vereinfachen die Arbeit mit dem Material. Die Übersetzung erfolgt in 18 Sprachen. Konkrete Anwendungsmöglichkeiten findet die Technologie für Content Creator, Studierende, Lehrende und Podcaster, die ihre Audio- und Videoinhalte erstmals strukturieren können. „Nutzerinnen und Nutzer können effizienter durch Videos und Vorträge navigieren, relevante Abschnitte schneller finden und wichtige Kerninhalte kompakt und effizient erfassen – sie haben insgesamt eine viel bessere grobe Übersicht sowie schnelleren Zugriff auf die Details“, sagt Waibel. Die Forschung fand im Projekt „How is AI Changing Science?“ statt und wurde für vier Jahre von der Volkswagenstiftung gefördert. Projektbeteiligte waren neben dem KIT die Universität Bonn sowie die Universität Wien. (mr/ase) Als „Die Forschungsuniversität in der Helmholtz-Gemeinschaft“ schafft und vermittelt das KIT Wissen für Gesellschaft und Umwelt. Ziel ist es, zu den globalen Herausforderungen maßgebliche Beiträge in den Feldern Energie, Mobilität und Information zu leisten. Dazu arbeiten rund 10 000 Mitarbeiterinnen und Mitarbeiter auf einer breiten disziplinären Basis in Natur-, Ingenieur-, Wirtschafts- sowie Geistes- und Sozialwissenschaften zusammen. Seine 22 800 Studierenden bereitet das KIT durch ein forschungsorientiertes universitäres Studium auf verantwortungsvolle Aufgaben in Gesellschaft, Wirtschaft und Wissenschaft vor. Die Innovationstätigkeit am KIT schlägt die Brücke zwischen Erkenntnis und Anwendung zum gesellschaftlichen Nutzen, wirtschaftlichen Wohlstand und Erhalt unserer natürlichen Lebensgrundlagen. Das KIT ist eine der deutschen Exzellenzuniversitäten.

Chemical cocktail from plastics: Pilot study describes degradation and leaching process of plastic consumer products

Plastic waste in rivers and oceans is constantly releasing chemicals into the water. Until now, it was unknown how large these quantities are and which substances are released particularly strongly. In the large-scale P-LEACH project, experts from four research institutes of the Helmholtz Association have now analyzed the composition and concentrations of many different substances. The main focus was on the question of how the sun's UV radiation increases the release of chemicals. Hundreds of thousands of tons of plastic waste are floating in rivers and oceans. The impact of waves, the sun's UV radiation and salty seawater cause the plastic to gradually break down into smaller and smaller fragments and ultimately float in the oceans as tiny microplastic particles. In numerous studies, researchers have investigated the extent to which marine animals ingest these particles and whether they become ill from them. Far less well researched to date is how the ingredients of various plastic products—including additives such as heavy metals, flame retardants, plasticizers, dyes and many other ingredients, that give plastic its versatile properties—affect marine life.
