Amazon is running a sale on its Blink home security devices. Among the items that have seen a price drop is the Blink Video Doorbell, which is available for a record low of 30. That's half what you might otherwise pay for it. The doorbell allows you to answer your door using your phone. You can see who rang your doorbell via a 1080p video stream (there's an infrared night vision mode) and chat to them using the two-way audio feature.

Generative artificial intelligence (GAI) started making waves a few years ago with the release of systems such as ChatGPT and DALL-E. They are able to produce sophisticated and human-like text, code, or images after the models powering them are trained on large quantities of data. However, it soon became apparent that the specific phrasing of a question or statement input by a user, known as a prompt, had an impact on the quality of the resulting output. "It's a way of unlocking different capabilities from these models," says Andrei Muresanu, an AI researcher at Vector Institute in Toronto, Canada. "If you tell ChatGPT to pretend that it's a professor of mathematics, it will do better on math questions than if you just say, 'answer this question' or'pretend you're a student'." Coming up with prompts that steer a model towards a desired output has emerged as a relatively new profession, called prompt engineering, to help achieve more relevant and accurate results.

A pair of studies analyzing the effects of AI on our planet have been released and the news is fairly grim. Greenpeace studied the emissions generated from the production of the semiconductors used in AI chips and found that there was a fourfold increase in 2024. This analysis was completed using publicly available data. Many of the big chipmakers like NVIDIA rely on companies like Taiwan Semiconductor Manufacturing Co and SK Hynix Inc. for the components of GPUs and memory units. Most of this manufacturing happens in Taiwan, South Korea and Japan, where power grids are primarily reliant on fossil fuels.

The two workers say their employment was terminated over the protests. Fox News' "Antisemitism Exposed" newsletter brings you stories on the rising anti-Jewish prejudice across the U.S. and the world. TOP STORY: Microsoft fired an employee who disrupted the company's 50th anniversary celebration event to voice their opposition to its work supplying artificial intelligence technology to Israel. As Microsoft AI CEO Mustafa Suleyman spoke at the event, Ibtihal Aboussad began shouting at him, accusing him of being "a war profiteer." She demanded that Suleyman "stop using AI for genocide."

Buying something in the shops used to be as simple as choosing the item and handing over the money. But in recent years, the great British shopping experience has dramatically changed. In 2025, artificial intelligence (AI) is patrolling Britain's retail stores to keep an eye on customers as they stock up on essentials. Now, people are subjected to a slew of AI-powered tech, including intelligent surveillance cameras, robots, facial recognition systems and online age checks. Home Bargains is the latest to follow the trend, with a new AI-enabled security system that watches you while you scan your own items.

For better or worse, AI tools have steadily become a reality of the academic landscape since ChatGPT launched in late 2022. Anthropic is studying what that looks like in real time. On Tuesday, shortly after launching Claude for Education, the company released data on which tasks university students use its AI chatbot Claude for and which majors use it the most. Using Clio, the company's data analysis tool, to maintain user privacy, Anthropic analyzed 574,740 anonymized conversations between Claude and users at the Free and Pro tiers with higher education email addresses. All conversations appeared to relate to coursework.

AI-controlled machines equipped with chilli pepper spray could reduce confrontations between bears and people. But the animals may learn to avoid these machines and simply head to homes and rubbish dumps without them. Incidents between people and Tibetan brown bears (Ursus arctos pruinosus), also known as Tibetan blue bears, on the Tibetan Plateau are escalating, perhaps at least partly due to climate change affecting the animals' usual territory.

The new Matter standard is getting better at helping Alexa, Apple HomeKit, Google Home, and Samsung SmartThings play nice with each other, but it often does so at the expense of finer-grained features. Some Matter-enabled smart lights, for example, can be turned on or off via Matter or change their color, but Matter controllers might not be able to access their lighting scenes or advanced animation modes. Likewise, smart home manufacturer Aqara found some of its hardware functionality hamstrung by Matter's limitations, such as the lack of Matter support for facial recognition (which might arrive once Matter finally works with security cameras), or for the fall-detection capabilities of its motion sensors. One option would be to wait for the Matter specification to catch up and add that functionality--which could take a while, given the slow pace of Matter specification updates. Instead, Aqara built its own workaround, which involves taking various Aqara scenes and "signals" and turning them into virtual sensors that Matter understands.

Russia's territorial gains in Ukraine are slowing down dramatically, two analyses have found, continuing a pattern from 2024 at a time when both nations are trying to project strength in the face of United States-mediated negotiations aimed at ending the war. Britain's Ministry of Defence last week estimated that Russian forces seized 143sq km (55sq miles) of Ukrainian land in March, compared with 196sq km (76sq miles) in February and 326sq km (126sq miles) in January. The Institute for the Study of War, a Washington, DC-based think tank, spotted the same trend, estimating Russian gains at 203sq km (78sq miles) in March, 354sq km (137sq miles) in February and 427sq km (165sq miles) in January. These estimates are based on satellite imagery and geolocated open-source photography rather than claims by either side. Should this trend continue, Russian forces could come to a standstill by early summer, roughly coinciding with US President Donald Trump's self-imposed early deadline for achieving a ceasefire.

Researchers at Bioinspired Robotics and Design Lab, UC San Diego created a fully 3D-printed, six-legged robot that walks using compressed air. It has no electronics, motors, or batteries--just soft actuators powered by gas. Tested on various terrains, it operates continuously with a steady air supply.
