Technology news

	An energy efficient transmitter based on a CMOS chip and silicon photonics The widespread use of electronic devices to interact with others and access the internet has increased the need for highly performing communication technologies that can transmit data faster and more efficiently. Increasing the data transmission rate of devices without adversely impacting their energy efficiency, however, is a challenging task.
	Tool detects AI-generated text in science journals In an era of heightened concern in academia regarding AI-generated essays, there is reassuring news from the University of Kansas.
	Battery materials: What is the battery of the future made of? The Empa research group led by Maksym Kovalenko is researching innovative materials for the batteries of tomorrow. Whether it's fast-charging electric cars or low-cost stationary storage, there's a promising material or a novel manufacturing process for every application.
	Scientists develop new method for electronic-to-multi-ionic signal transmission In biological systems, complex neuronal networks with highly polarized synaptic gating interfaces are responsible for processing and transmitting intricate biosignals.
	Study shows languages with more speakers tend to be harder for machines to learn Just a few months ago, many people would have found it unimaginable how well artificial intelligence-based "language models" could imitate human speech. What ChatGPT writes is often indistinguishable from human-generated text.
	Humans vs. robots: Study compares 27 humanoid robots with humans to see who is superior Science fiction films portray the idea relatively simply: the terminator—who either tries to destroy or rescue humanity—is such a perfect humanoid robot that in most cases it is superior to humans. But how well do humanoid robots perform nowadays away from the cinema screen?
	Machine learning gives users 'superhuman' ability to open and control tools in virtual reality Researchers have developed a virtual reality application where a range of 3D modeling tools can be opened and controlled using just the movement of a user's hand.
	OpenAI sees a future of AI 'superpowers on demand' ChatGPT maker OpenAI on Monday moved to entice developers with lower prices and the ability to easily tailor artificial intelligence "agents" to help with anything from laundry advice to contract negotiations.
	With electric vehicle sales growth slowing, Stellantis Ram brand has an answer: An onboard charger One of the biggest reasons people cite when saying they won't buy an electric vehicle is range anxiety, the fear of running out of juice on the road with nowhere to recharge.
	Japan's Nintendo profits jump as its game sales get a boost from the hit Super Mario movie Nintendo reported an 18% rise in net profit for its first fiscal half on Tuesday, as sales continued to get a boost from its hit Super Mario movie, and the popularity of its software for various new video games.
	Why surging sales of large electric vehicles raises environmental red flags Electric cars are getting bigger and heavier. In 2019, 30% of the electric vehicle (EV) models available worldwide were sports utility vehicles (SUVs).
	New possibilities of 2PP 3D-printing for complex microstructures In a series of studies, scientists from the NeptunLab at the University of Freiburg (Germany) have pushed the potential of 2-photon polymerization 3D-printing (2PP 3D-printing) beyond existing limits. Having demonstrated their ability to print complex platinum 3D microstructures with an astonishing sub-micron resolution in 2021, this year the team succeeded in producing similar structures made of tungsten as well as embedded microfluidic chips with single μm resolution at unprecedented speed.
	Researchers are creating science-backed tools to improve social media content moderation policies Flagging, demotion, and deletion of content; temporary or permanent suspension of users—these are some of the interventions used to keep social media platforms safe, trustworthy, and free from harmful content. But what is the best way for these interventions to be implemented? Luca Luceri, a research scientist at USC's Information Sciences Institute (ISI), is part of a team that is using science to guide social media regulations.
	A Meta engineer saw his own child face harassment on Instagram. Now, he's testifying before Congress On the same day whistleblower Frances Haugen was testifying before Congress about the harms of Facebook and Instagram to children in the fall of 2021, a former engineering director at the social media giant who had rejoined the company as a consultant sent an alarming email to Meta CEO Mark Zuckerberg about the same topic.
	Novel molecular bridge strategy boosts efficiency of perovskite solar cells Recently, a research team by Professor Pan Xu from Institute of Solid-State Physics, Hefei Institutes of Physical Science (HIPS) of Chinese Academy of Sciences (CAS) proposed a novel strategy to enhance the performance of perovskite solar cells. Their strategy involves the creation of a robust connection between different layers of the solar cell using a molecular bridge made of ammonium cations.
	'Crowding out' the competition: Study reveals surprising livestream chatting and tipping behavior Over the past decade, social media giants including X (formerly known as Twitter), Facebook, YouTube, Amazon and Twitch have begun offering livestreaming services, allowing users to interact with each other in real time on their computers and mobile phones.
	Tech giants pool efforts to fight online child sex abuse Big tech companies, including Facebook-owner Meta and Google, said Tuesday they would team up in a new program to fight online child sexual abuse or exploitation.
	Fake Bollywood video highlights AI worries in India A fake video of a Bollywood actor purporting to show her wearing a low-cut top has triggered calls for AI regulation in India, where past false social media posts have stoked sectarian divisions.
	Former Meta engineer testifies before Congress on Instagram's harms to teens On the same day whistleblower Frances Haugen was testifying before Congress about the harms of Facebook and Instagram to children in the fall of 2021, Arturo Béjar, then a contractor at the social media giant, sent an alarming email to Meta CEO Mark Zuckerberg about the same topic.
	Chinese tech mogul not seen in weeks after official probe: reports The boss of a leading Chinese livestreaming platform has not been seen in public for weeks, state-run media outlets reported, after an investigation into illegal content on his site.
	New open-access book on 5G, 6G and future digital services released In a rapidly digitizing world, staying ahead of the curve requires a deep understanding of the evolving mobile communications landscape. A new open-access book titled "The Changing World of Mobile Communications: 5G, 6G and the Future of Digital Services" has been released to shed light on this transformation.
