Tesla Cybercab: hate it or love it, it is the most efficient EV ever

Tesla Cybercab: hate it or love it, it is the most efficient EV ever

Tesla’s Cybercab has been certified at 165 Wh/mi, making it the most efficient electric vehicle ever produced — by a wide margin. The next most efficient EV on the market, the Lucid Air Pure, consumes 28% more energy per mile. Tesla VP of Vehicle Engineering Lars Moravy confirmed the figure, which represents a certified rating — not a marketing claim or internal target. It’s an impressive achievement, but it comes with a massive asterisk: Tesla accomplished this by building a tiny two-seat robotaxi with no steering wheel, no pedals, and a sub-50 kWh battery pack. How the Cybercab compares to every other EV To put 165 Wh/mi in context, here’s how it stacks up against the most efficient EVs currently rated by the EPA: Tesla Cybercab: 165 Wh/mi Lucid Air Pure RWD (19″): 230 Wh/mi — 28% less efficient Tesla Model 3 RWD (18″): 240 Wh/mi — 31% less efficient Tesla Model Y RWD (18″): 240 Wh/mi — 31% less efficient Hyundai Ioniq 6 SE RWD (18″): 241 Wh/mi — 32% less efficient Toyota bZ3X …

Nigel Farage will need to be 22 times more efficient to win the next general election – POLITICO

Nigel Farage will need to be 22 times more efficient to win the next general election – POLITICO

Although the U.K. does not elect a president, it has for decades been true that many voters base their decisions on who they want in No. 10 Downing Street (or who they really want to keep away from that famous black door). Here, Farage is not, apparently, a runaway success.  According to YouGov’s most recent survey, on May 4-5, the Reform UK leader’s net favorability score is -39 percent, only a little better than Starmer’s score of -47 percent. Of the leaders and potential leaders polled, only Labour’s Manchester Mayor Andy Burnham has a net positive rating, of 4 percent. On the economy, too, Reform’s reputation leaves room for doubters. On May 4, YouGov found only 11 percent of voters thought Farage’s party would be the best at handling the economy, compared to 15 percent for Labour and 19 percent for the Conservatives.  Despite these caveats, politics is changing. As Farage has already shown, what held sway in the past is not necessarily a guide to what will happen next. A big 80-seat win for …

Meet ZAYA1-8B, a super efficient, open reasoning model trained on AMD Instinct MI300 GPUs

Meet ZAYA1-8B, a super efficient, open reasoning model trained on AMD Instinct MI300 GPUs

Even as leading AI providers like OpenAI and Anthropic battle over the compute to train and release ever larger, more powerful models, other labs are going in a different direction — pursuing the development of smaller, more efficient models and often open sourcing them. The latest worth paying attention to comes from the lesser-known Palo Alto startup Zyphra, which this week released its new reasoning, mixture-of-experts (MoE) language model, ZAYA1-8B, with just over 8 billion parameters and only 760 million active — far fewer than the trillions estimated for the likes of the big labs. Yet, ZAYA1-8B retains competitive performance on third-party benchmarks against GPT-5-High and DeepSeek-V3.2. It can be downloaded from Hugging Face now free of charge under a permissive, standard, enterprise-friendly Apache 2.0 license — and enterprises and indie developers can begin using and customizing it immediately to suit their needs. Individual users can also test it themselves here free at Zyphra Cloud, the startup’s inference solution. But the real headline is what ZAYA1-8B was trained on: a full stack of AMD Instinct …

Open source Xiaomi MiMo-V2.5 and V2.5-Pro are among the most efficient (and affordable) at agentic ‘claw’ tasks

Open source Xiaomi MiMo-V2.5 and V2.5-Pro are among the most efficient (and affordable) at agentic ‘claw’ tasks

Xiaomi, the Chinese firm best known for its smartphones and electric vehicles, has lately been shipping some incredibly affordable and high-powered open source AI large language models. The trend continued today with the release of Xiaomi MiMo-V2.5 and Xiaomi MiMo-V2.5-Pro, both available under the permissive, enterprise-friendly MIT License, making them suitable for use in production in commercial applications. Enterprises and individual/independent developers can now download either of the models (and more Xiaomi open source options) directly from Hugging Face, modify them as needed, and run them locally or on virtual private clouds as they see fit. The most notable attribute of these models besides the open source licensing is that, according to Xiaomi’s published benchmarks, they are among the most efficient available for agentic “claw” tasks, that is, powering systems such as OpenClaw, NanoClaw and Hermes Agent, in which users can communicate with them directly over third-party messaging apps and have the agents go off and complete tasks on the human user’s behalf, such as making and publishing marketing content, running accounts, organizing email and …

Co-occurring depression and cannabis use linked to less efficient brain networks

Co-occurring depression and cannabis use linked to less efficient brain networks

New research published in Drug and Alcohol Dependence provides evidence that experiencing depression symptoms alongside cannabis use is linked to less efficient communication across the brain compared to cannabis use alone. The study suggests that while cannabis use tends to increase overall connectivity in the brain, the presence of depression weakens this effect, resulting in a less integrated brain network. Scientists conducted this study to better understand the underlying biology of why cannabis use and depression frequently occur together. Heavy or chronic cannabis use might increase the risk of developing depression, while individuals experiencing depression often turn to cannabis to self-medicate. Both cannabis use and depression individually alter the way different areas of the brain communicate with each other. This baseline brain communication is known as resting-state functional connectivity, which refers to the brain activity that happens when a person is awake but not focused on a specific task. Prior studies have shown changes in resting-state connectivity in people who use cannabis and in those with depression, but the combined effect of both factors on …

Audi to launch new electric A2 e-tron: ‘Efficient, compact, and confident’

Audi to launch new electric A2 e-tron: ‘Efficient, compact, and confident’

Get our weekly Drive Smart newsletter for motoring news, reviews and advice from EV editor Steve Fowler Get motoring news, reviews and advice from EV editor Steve Fowler Get our EV editor’s weekly Drive Smart newsletter Audi has confirmed the revival of its A2 nameplate, set to return as an all-electric model dubbed the A2 e-tron. The original A2, first introduced in 2000, was a pioneering city car lauded for its futuristic design, exceptional interior space, and impressive efficiency. Its innovative construction featured an almost entirely aluminium bodyshell and key panels, which significantly reduced weight and contributed to a remarkably low drag coefficient, optimising fuel consumption. The forthcoming A2 e-tron is expected to emulate these “groundbreaking methods,” promising a modern interpretation of its predecessor’s core values. Audi has confirmed the new electric vehicle will be fully unveiled later this year. Though details on the new model are scarce, Audi has said that the new car will be focused on people who value ‘everyday usability in the city’, suggesting that the upcoming model will be focused …

New ‘vacuum ultraviolet’ laser is 100 to 1,000 times more efficient than existing tech

New ‘vacuum ultraviolet’ laser is 100 to 1,000 times more efficient than existing tech

The vacuum ultraviolet region is the area of the electromagnetic spectrum lying between X-rays and visible light. It is characterized by very short wavelengths between about 100 and 200 nanometers. For many years, it has resisted development into practical lasers using existing laser techniques due to an almost laughable limitation. Virtually everything in our environment absorbs vacuum ultraviolet radiation instead of allowing it to pass through. For example, air, materials containing organic molecules, and many solid materials absorb it. Many types of atoms also absorb vacuum ultraviolet light rather than allowing it to pass. Yet that same property provides scientists with a wealth of scientific information about the material interactions of whatever vacuum ultraviolet photons encounter. Producing sufficient quantities of vacuum ultraviolet light in an efficient and compact device for practical use has therefore always represented a challenge. Building a Vacuum Ultraviolet Laser Now, researchers at the University of Colorado Boulder believe they have overcome this long-standing challenge by building a vacuum ultraviolet laser that is 100 to 1,000 times more efficient than currently available …

Black Forest Labs’ new Self-Flow technique makes training multimodal AI models 2.8x more efficient

Black Forest Labs’ new Self-Flow technique makes training multimodal AI models 2.8x more efficient

To create coherent images or videos, generative AI diffusion models like Stable Diffusion or FLUX have typically relied on external “teachers”—frozen encoders like CLIP or DINOv2—to provide the semantic understanding they couldn’t learn on their own. But this reliance has come at a cost: a “bottleneck” where scaling up the model no longer yields better results because the external teacher has hit its limit. Today, German AI startup Black Forest Labs (maker of the FLUX series of AI image models) has announced a potential end to this era of academic borrowing with the release of Self-Flow, a self-supervised flow matching framework that allows models to learn representation and generation simultaneously. By integrating a novel Dual-Timestep Scheduling mechanism, Black Forest Labs has demonstrated that a single model can achieve state-of-the-art results across images, video, and audio without any external supervision. The technology: breaking the “semantic gap” The fundamental problem with traditional generative training is that it’s a “denoising” task. The model is shown noise and asked to find an image; it has very little incentive to …

The Best Smart Sleep Pads for Your Most Efficient Sleep (2026)

The Best Smart Sleep Pads for Your Most Efficient Sleep (2026)

Sleep tech only seems to be getting more pervasive, permanent, and pricey. One day, you start checking your sleep rings on your Apple Watch, the next, you find yourself shopping for smart mattresses that require you to rethink your entire bed, fans that blow cool air under your duvet, and subscription apps that promise sleep coaching with hyper-granular data. Smart sleep pads are a good middle ground. They don’t require you to replace your bed and frame, strap anything to your body, or radically change your routine. They just sit on or underneath your mattress or pillow, and quietly do their thing—from tracking to temperature regulation—while you sleep. Some smart sleep pads adjust temperature, while others monitor movement or ever-so-slightly influence your sleep patterns. Either way, they’re easy to live with, which feels closer to how we think tech should behave at night. I tested several sleep pads on the same bed, during a Midwestern winter, to see which ones truly felt like they made a difference, and which felt more like experiments than solutions. …
