Google Insider Claims Company's "Sentient" AI Has Hired an Attorney
Fair Representation Google's controversial new AI, LaMDA, has been making headlines . Company engineer Blake Lemoine claims the system has gotten so advanced that it's developed sentience, and his decision to go to the media has led to him being suspended from his job.

Crossing fire threshold can quickly turn blazes dangerous
Global climate change has already exacerbated the risk of fire and is likely to fuel even more change as accelerating feedback loops create disastrous consequences for both biodiversity and human populations. Yet accurately predicting the risks and impact of bush and wildfire globally is still a work in progress.

Team develops powerful new tool to aid in battle against cancer-causing bacteria in the stomach
Helicobacter pylori (H. pylori), the bacteria that can cause human gastritis, peptic ulcers and stomach cancer, infects about half of the world's population. It is essential to quickly identify the infection and select the right combination of sensitive antibiotics. Current tools, however, are limited, mainly because H. pylori are slow-growing and hard to cultivate.

Why vaccination against malaria quickly loses its protective effect
Scientists have studied the human immune response after immunization with the malaria pathogen Plasmodium falciparum. Their findings could explain why natural infections, to which people in endemic areas are constantly exposed, offer little protection against new diseases with other strains, and why the effect of the vaccination available to date lasts only a short time.

Global stable-isotope tracing metabolomics reveals system-wide metabolic alternations in aging Drosophila
Nature Communications, Published online: 20 June 2022; doi:10.1038/s41467-022-31268-6 Stable-isotope tracing allows quantifying metabolic activity by measuring isotopically labeled metabolites, but its metabolome coverage has been limited. Here, the authors develop a global isotope tracing approach with metabolome-wide coverage and use it to characterize metabolic activities in aging Drosophila.

Britain's Unbridgeable Divide
B ritain today is a poor and divided country. Parts of London and the southeast of England might be among the wealthiest places on the planet, but swaths of northern England, Wales, Scotland, and Northern Ireland are among Western Europe's poorest. Barely a decade ago, the average Brit was as wealthy as the average German. Now they are about 15 percent poorer—and 30 percent worse off than the typ

The government pretends that farming and the countryside are synonymous – and our environment suffers as a result We have a problem. The environment secretary, George Eustice – the highest green authority in the land – is, in a crucial respect, a climate denier. In an interview with the Telegraph, he claimed that "livestock, particularly if you do it with the right pastoral system, has a role to

Is it fair to describe a human as a system running 2 mandatory functions
Is it fair to describe a human as a system that's based on the same instructions as all systems above us, including the universe itself, which involve 2 functions always set to ON; those functions being Self-Correct (survive, adapt) Self-Duplicate (procreate) in that order, too (obviously), because that allows for the parent to have been faced with novel challenges and threats to overcome, updati

Scientists Suggest Killing Ants With Viruses
Invaders Scientists say they've figured out at least part of North America's invasive, imported fire ant problem by turning a virus that kills them into a weapon. A group of researchers from Tennessee, Florida and North Carolina universities said in their new study, published in the print edition of the Journal of Invertebrate Pathology this month, that they successfully reduced wild Florida popu

Elon Musk Says Starlink's Default WiFi Name Will Be "Stinky"
Day Job If there's one thing you can always rely on Elon Musk for it's a good laugh. The Tesla, SpaceX and possibly-Twitter head has a decent sense of humor and said online yesterday that he was changing the default WiFi router name for Starlink. "We're changing Starlink's default wifi name to Stinky," Musk tweeted. The implication being, of course, that when you set up Starlink wifi for the firs
