	Soft robot fingers that can carefully squeeze without sensors With a brief squeeze, you know whether an avocado, peach or tomato is ripe. This is what a soft robot hand also does, for example, during automated harvesting. However, up until now, such a gripper needed sensors in its 'fingers' to determine whether the fruit was ripe enough.
	A new way to let AI chatbots converse all day without crashing When a human-AI conversation involves many rounds of continuous dialogue, the powerful large language machine-learning models that drive chatbots like ChatGPT sometimes start to collapse, causing the bots' performance to rapidly deteriorate.
	Modeling shows green roofs can cool cities and save energy Extensive greenery coverage on building rooftops could significantly reduce temperatures at the city scale and decrease energy costs, according to a new study.
	Fiber optic cables are an effective way to detect tsunamis, researchers show Fiber optic cables that line ocean floors could provide a less expensive, more comprehensive alternative to the current buoys that act as early warning systems for tsunamis, says a University of Michigan researcher.
	Study reveals eco-friendly way to generate power from waste wood A new study by researchers at University of Limerick in Ireland has revealed a sustainable method of efficiently converting waste heat into electricity using Irish wood products, while minimizing costs and environmental impact.
	Bitcoin breaks $50,000 for first time since 2021 Bitcoin spiked above $50,000 Tuesday for the first time in more than two years as investors grow optimistic that US approval of broader trading in the unit will ramp up demand.
	OpenAI CEO warns that 'societal misalignments' could make artificial intelligence dangerous The CEO of ChatGPT-maker OpenAI said Tuesday that the dangers that keep him awake at night regarding artificial intelligence are the "very subtle societal misalignments" that could make the systems wreak havoc.
	Apple's iMessage, Microsoft's Bing escape EU rules Apple's iMessage and Microsoft's Bing search engine got a reprieve from tougher EU rules curbing how tech titans do business, the European Commission said on Tuesday.
	Our robot harvests cotton by reaching out and plucking it, like a lizard's tongue snatching flies Cotton is one of the most valuable crops grown in the U.S., with a harvest value of some US$7 billion yearly. It is cultivated across a crescent of 17 states stretching from Virginia to California and is used in virtually every type of clothing, as well as in medical supplies and home goods such as upholstery.
	The problems with dating apps and how they could be fixed—two relationship ethicists explain Hundreds of millions of people worldwide use dating apps. But only half of users say that they have had positive experiences. Indeed, a shocking 11% of female users under 50 have received threats of harm. Surely there's a better way to build these apps.
	Shrinkage porosity identified in laser powder bed fusion additive manufacturing When Mechanical Engineering Ph.D. candidate William Frieden Templeton intended to take a closer look at how laser powder bed fusion (PBF-LB) process parameters influence microstructure, he never expected to find a manufacturing defect previously overlooked in PBF-LB additive manufacturing.
	EU industries seek to profit from materials in wastewater For decades, most of the wastewater from the Mahou San Miguel brewery in the northeastern Spanish city of Lleida was flushed down the drain.
	Build biorefineries and let the natural world power Mexico's economy, suggests researcher Mexico could grow its economy while saving the planet by building biorefineries that can turn seaweed, sugar cane, cooking oil and even vegetable peel into fuel and pharmaceuticals. Now, the country needs a new 'bioeconomy plan' to unlock its potential, according to a large study from the University of Surrey and Mexico's Instituto Mexicano del Petroleo, published in the Journal of Cleaner Production.
	Can AI write laws? Lawyer puts ChatGPT to the test A Charles Darwin University (CDU) academic has answered one of the modern-day legal world's most burning questions: Can Artificial Intelligence (AI) write laws?
	Road features that predict crash sites identified in new machine-learning model Issues such as abrupt changes in speed limits and incomplete lane markings are among the most influential factors that can predict road crashes, finds new research by University of Massachusetts Amherst engineers. The study then used machine learning to predict which roads may be the most dangerous based on these features.
	Benefits of heat pumps detailed in new report Millions of U.S. households would benefit from heat pumps, but the cost of installing the technology needs to come down to make their use a more attractive proposition, according to researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL).
	Stable profits, land preservation matter to farmers debating solar leases To solar or not to solar? While a stable and predictable profit is an important factor to Pennsylvania farmers considering leasing out their land for solar energy development, it's not enough on its own, according to a new study led by Penn State researchers.
	Algorithms don't understand sarcasm. Yeah, right! Sarcasm, a complex linguistic phenomenon often found in online communication, often serves as a means to express deep-seated opinions or emotions in a particular manner that can be in some sense witty, passive-aggressive, or more often than not demeaning or ridiculing to the person being addressed. Recognizing sarcasm in the written word is crucial for understanding the true intent behind a given statement, particularly when we are considering social media or online customer reviews.
	Research describes new protocol for stopping network interlopers Dr. Santosh Ganji, a recent computer engineering doctoral graduate, and Dr. P.R. Kumar, a professor in the Department of Electrical and Computer Engineering at Texas A&M University College of Engineering, work on the security of wireless networks.
	Biden on TikTok: 'lol' or national security worry? US President Joe Biden's debut on TikTok has caused a stir—not least because the Chinese-owned social media platform is still officially considered a security risk by Washington.
	Super Bowl draws record 123 million US viewers A record 123.4 million people tuned in to watch the Kansas City Chiefs beat the San Francisco 49ers in Sunday's Super Bowl—with the added attraction of an Usher-headlined halftime show and the attention-stealing presence of Taylor Swift.
	Cyberattack shuts down Colorado public defender's office A cyberattack on the Office of Colorado State Public Defender has forced the office to shut down its computer network, locking public defenders across the state out of critical work systems.
	Tech layoffs signal 'feeling economy' shift Tech company layoffs exceeded 260,000 in 2023, and continue in 2024. This, despite a robust job market in non-tech industries.
