	Molecular engineering advances lithium-metal batteries, paving the way for safer, more powerful devices The boom in phones, laptops and other personal devices over the last few decades has been made possible by the lithium-ion (Li-ion) battery, but as climate change demands more powerful batteries for electric vehicles and grid-scale renewable storage, lithium-ion technology might not be enough.
	New algorithm finds failures and fixes in autonomous systems, from drone teams to power grids From vehicle collision avoidance to airline scheduling systems to power supply grids, many of the services we rely on are managed by computers. As these autonomous systems grow in complexity and ubiquity, so too could the ways in which they fail.
	New AI noise-canceling headphone technology lets wearers pick which sounds they hear Most anyone who's used noise-canceling headphones knows that hearing the right noise at the right time can be vital. Someone might want to erase car horns when working indoors, but not when walking along busy streets. Yet people can't choose what sounds their headphones cancel.
	How to use AI for discovery without leading science astray Over the past decade, AI has permeated nearly every corner of science: Machine learning models have been used to predict protein structures, estimate the fraction of the Amazon rainforest that has been lost to deforestation and even classify faraway galaxies that might be home to exoplanets.
	Developing 'indoor solar' to power the Internet of Things From Wi-Fi-connected home security systems to smart toilets, the so-called Internet of Things brings personalization and convenience to devices that help run homes. But with that comes tangled electrical cords or batteries that need to be replaced. Now, researchers reporting in ACS Applied Energy Materials have brought solar panel technology indoors to power smart devices. They show which photovoltaic (PV) systems work best under cool white LEDs, a common type of indoor lighting.
	Indonesia inaugurates Southeast Asia's largest floating solar farm Indonesia inaugurated a $100 million floating solar farm on Thursday, the largest in Southeast Asia, as it seeks more opportunities to transition to green, renewable energy.
	Disney+ adds subscribers amid cost-cutting campaign Disney's streaming service has attracted nearly seven million new subscribers, the company said Wednesday, reversing a period of decline that had raised doubts about its rivalry with industry leader Netflix.
	Generative AI explained A quick scan of the headlines makes it seem like generative artificial intelligence is everywhere these days. In fact, some of those headlines may actually have been written by generative AI, like OpenAI's ChatGPT, a chatbot that has demonstrated an uncanny ability to produce text that seems to have been written by a human.
	AI startup Anthropic to use Google chips in expanded partnership Artificial intelligence startup Anthropic will be one of the first companies to use new chips from Alphabet Inc."s Google, deepening their partnership after a recent cloud computing agreement.
	How to never get a speeding fine again, and maybe save a child's life What if our cars didn't allow us to speed? Or, at least, strongly encouraged us not to speed?
	41 US states are suing Meta for getting teens hooked on social media: Here's what to expect next In the United States, 41 states have filed lawsuits against Meta for allegedly driving social media addiction in its young users (under the age of 18), amid growing concerns about the negative effects of platforms.
	Internet of Things: Tech firms have become digital landlords, but people are starting to fight back From smart toasters to fitness collars for dogs, we live in a world where everything around us is gradually being connected to the internet and fitted with sensors so that we can interact with them online.
	General aviation sector grounded by red tape and sky-high costs, says research Red tape, over-regulation, spiraling costs and a vacuum of government policy are putting significant pressure on the general aviation sector in Australia, according to a survey of industry chiefs.
	Fresh water is a hidden challenge, and opportunity, for global supply chains Reports of lengthy shipping delays for vessels traveling through the Panama Canal this year have highlighted the critical but often overlooked role that fresh water plays across global supply chains. Drier than normal conditions in Panama, brought on by El Niño, have left the region drought-stricken and water levels in the locks that feed the canal lower than normal. This has led to fewer ships being able to pass through the canal each day: only 31 ships currently, compared with 36 to 38 under normal conditions. This means longer waits to move products through the canal and onto store shelves.
	Concrete versus asphalt for Nigeria's roads: which is better? Nigeria's new works minister, David Umahi, is pushing for the use of rigid pavement in road construction, as against the flexible pavement predominantly in use. This, as the minister noted, is due to the precarious state of flexible pavements in the country.
	Deep learning-based system paves the way for efficient battery health assessment As the electric vehicle market continues to surge, the assessment of used batteries has become increasingly crucial. A team of researchers, led by Professor Donghyuk Kim and Professor Yunseok Choi in the School of Energy and Chemical Engineering at UNIST, along with Professor Hankwon Lim of the Graduate School of Carbon Neutrality at UNIST, has developed DeepSUGAR to help with this challenge.
	How human faces can teach androids to smile Robots able to display human emotion have long been a mainstay of science fiction stories. Now, Japanese researchers have been studying the mechanical details of real human facial expressions to bring those stories closer to reality.
	EU court advisor deals blow to Apple in Ireland tax case The European Court of Justice's top legal advisor recommended Thursday scrapping a previous Apple victory against Brussels in a 13-billion-euro ($14-billion) tax case, a blow to the iPhone-maker in a long-running legal saga.
