Around the world fungal infections kill an estimated 2.5 million people a year, notes a report from CNN. But new research predicts that certain species of infection-causing Aspergillus fungi could spread into new areas as the earth's temperature rises. ("The study, published this month, is currently being peer reviewed...") Aspergillus fungi grow like small filaments in soils all over the world. Like almost all fungi, they release huge numbers of tiny spores that spread through the air. Humans inhale spores every day but most people won't experience any health issues; their immune system clears them. It's a different story for those with lung conditions including asthma, cystic fibrosis and COPD, as well as people with compromised immune systems, such as cancer and organ transplant patients, and those who have had severe flu or Covid-19. If the body's immune system fails to clear the spores, the fungus "starts to grow and basically kind of eat you from the inside out, saying it really bluntly," said Norman van Rijn, one of the study's authors and a climate change and infectious diseases researcher at the University of Manchester. Aspergillosis has very high mortality rates at around 20% to 40%, he said. It's also very difficult to diagnose, as doctors don't always have it on their radar and patients often present with fevers and coughs, symptoms common to many illnesses. Fungal pathogens are also becoming increasingly resistant to treatment, van Rijn added. There are only four classes of antifungal medicines available... Aspergillus flavus, a species that tends to prefer hotter, tropical climates, could increase its spread by 16% if humans continue burning large amounts of fossil fuels, the study found... [Mainly in parts of Europe and the northernmost edges of Scandinavia, Russia, China, and Canada, and the western edge of Alaska.] This species can cause severe infections in humans and is resistant to many antifungal medications. It also infects a range of food crops, posing a potential threat to food security. The World Health Organization added Aspergillus flavus to its critical group of fungal pathogens in 2022 because of its public health impact and antifungal resistance risk... Conversely, temperatures in some regions, including sub-Saharan Africa, could become so hot they are no longer hospitable to Aspergillus fungi. This could bring its own problems, as fungi play an important role in ecosystems, including healthy soils. As well as expanding their growing range, a warming world could also be increasing fungi's temperature tolerance, allowing them to better survive inside human bodies. Extreme weather events such as drought, floods and heatwaves can affect fungi, too, helping to spread spores over long distances. Thanks to Slashdot reader quonset for sharing the article.

A year ago, the original creator of SerenityOS posted that "for the past two years, I've been almost entirely focused on Ladybird, a new web browser that started as a simple HTML viewer for SerenityOS." So it became a stand-alone project that "aims to render the modern web with good performance, stability and security." And they're also building a new web engine. "We are building a brand-new browser from scratch, backed by a non-profit..." says Ladybird's official web site, adding that they're driven "by a web standards first approach." They promise it will be truly independent, with "no code from other browsers" (and no "default search engine" deals). "We are targeting Summer 2026 for a first Alpha version on Linux and macOS. This will be aimed at developers and early adopters." More from the Ladybird FAQ: We currently have 7 paid full-time engineers working on Ladybird. There is also a large community of volunteer contributors... The focus of the Ladybird project is to build a new browser engine from the ground up. We don't use code from Blink, WebKit, Gecko, or any other browser engine... For historical reasons, the browser uses various libraries from the SerenityOS project, which has a strong culture of writing everything from scratch. Now that Ladybird has forked from SerenityOS, it is no longer bound by this culture, and we will be making use of 3rd party libraries for common functionality (e.g image/audio/video formats, encryption, graphics, etc.) We are already using some of the same 3rd party libraries that other browsers use, but we will never adopt another browser engine instead of building our own... We don't have anyone actively working on Windows support, and there are considerable changes required to make it work well outside a Unix-like environment. We would like to do Windows eventually, but it's not a priority at the moment. "Ladybird's founder Andreas Kling has a solid background in WebKit-based C++ development with both Apple and Nokia,," writes software developer/author David Eastman: "You are likely reading this on a browser that is slightly faster because of my work," he wrote on his blog's introduction page. After leaving Apple, clearly burnt out, Kling found himself in need of something to healthily occupy his time. He could have chosen to learn needlepoint, but instead he opted to build his own operating system, called Serenity. Ladybird is a web project spin-off from this, to which Kling now devotes his time... [B]eyond the extensive open source politics, the main reason for supporting other independent browser projects is to maintain diverse alternatives — to prevent the web platform from being entirely captured by one company. This is where Ladybird comes in. It doesn't have any commercial foundation and it doesn't seem to be waiting to grab a commercial opportunity. It has a range of sponsors, some of which might be strategic (for example, Shopify), but most are goodwill or alignment-led. If you sponsor Ladybird, it will put your logo on its webpage and say thank you. That's it. This might seem uncontroversial, but other nonprofit organisations also give board seats to high-paying sponsors. Ladybird explicitly refuses to do this... The Acid3 Browser test (which has nothing whatsoever to do with ACID compliance in databases) is an old method of checking compliance with web standards, but vendors can still check how their products do against a battery of tests. They check compliance for the DOM2, CSS3, HTML4 and the other standards that make sure that webpages work in a predictable way. If I point my Chrome browser on my MacBook to http://acid3.acidtests.org/, it gets 94/100. Safari does a bit better, getting to 97/100. Ladybird reportedly passes all 100 tests. "All the code is hosted on GitHub," says the Ladybird home page. "Clone it, build it, and join our Discord if you want to collaborate on it!"

Whether General Motors survives "depends in part on whether its bets on battery technology pay off," writes the Wall Street Journal. At $33,600 the company's Chevy Equinox is one of the cheapest EVs in America (only $5,000 more than the gas-powered model). "But it also recently announced a novel type of battery that promises to be significantly cheaper, while still providing long range, due to be rolled out in 2028..." Like many of its competitors, GM has made huge investments in EV battery factories, and in production lines for the vehicles themselves, and it faces challenges in generating a return on investment in the short term... In the long run, however, GM's focus on creating a North American supply chain for batteries could prove savvy, says David Whiston, U.S. auto equities analyst at Morningstar. The company is investing $625 million to mine lithium in Nevada. It is working on sourcing every material and every part in its batteries domestically, down to the copper and aluminum foils that go into its cells, says [battery and sustainability lead Kurt] Kelty... GM recently unveiled a new type of battery the company has been working on for a decade called lithium manganese-rich batteries, or LMR. These batteries combine the low cost of LFP batteries with the longer range of conventional, expensive lithium-ion batteries. What makes LMR batteries more affordable is that they use far less nickel, cobalt and other minerals that have become increasingly expensive. Instead, they use more manganese, a common element... The company's next initiative, says Kelty, is to further drive down the cost of its batteries by putting more of another common element, silicon, into them. "If GM can continue to grow demand for its EVs, in a few years the rollout of its latest tech could give it a price and performance advantage..." the article points out. While the EV transition is happening more slowly than projected in the U.S., GM hiring Kelty is a bet that the country's current EV struggles are temporary, and that technologists like Kelty will help GM get past them. "When we reach cost parity with [internal combustion engine] vehicles, I think that's one big milestone," says Kelty. "When you get there, then you're really going to see the transition happen very quickly — and we're not that far away from it."
