AI needs to be smaller, reduce energy footprint: study
PARIS: The potential of artificial intelligence is immense -- but its equally vast energy consumption needs curbing, with asking shorter questions one way to achieve, said a UNESCO study unveiled Tuesday.

AI video becomes more convincing, rattling creative industry
NEW YORK: Gone are the days of six-fingered hands or distorted faces – AI-generated video is becoming increasingly convincing, attracting Hollywood, artists, and advertisers, while shaking the foundations of the creative industry. To measure the progress of AI video, you need only look at Will Smith eating spaghetti. Since 2023, this unlikely sequence – entirely fabricated – has become a technological benchmark for the industry. Two years ago, the actor appeared blurry, his eyes too far apart, his forehead exaggeratedly protruding, his movements jerky, and the spaghetti didn't even reach his mouth. The version published a few weeks ago by a user of Google's Veo 3 platform showed no apparent flaws whatsoever. "Every week, sometimes every day, a different one comes out that's even more stunning than the next," said Elizabeth Strickler, a professor at Georgia State University. Between Luma Labs' Dream Machine launched in June 2024, OpenAI's Sora in December, Runway AI's Gen-4 in March 2025, and Veo 3 in May, the sector has crossed several milestones in just a few months. Runway has signed deals with Lionsgate studio and AMC Networks television group. Lionsgate vice president Michael Burns told New York Magazine about the possibility of using artificial intelligence to generate animated, family-friendly versions from films like the John Wick or Hunger Games franchises, rather than creating entirely new projects. "Some use it for storyboarding or previsualisation" – steps that come before filming – "others for visual effects or inserts," said Jamie Umpherson, Runway's creative director. Burns gave the example of a script for which Lionsgate has to decide whether to shoot a scene or not. To help make that decision, they can now create a 10-second clip "with 10,000 soldiers in a snowstorm." That kind of pre-visualisation would have cost millions before. In October, the first AI feature film was released – Where The Robots Grow – an animated film without anything resembling live action footage. For Alejandro Matamala Ortiz, Runway's co-founder, an AI-generated feature film is not the end goal, but a way of demonstrating to a production team that "this is possible". 'Resistance everywhere' Still, some see an opportunity. In March, startup Staircase Studio made waves by announcing plans to produce seven to eight films per year using AI for less than US$500,000 (RM2.11mil) each, while ensuring it would rely on unionised professionals wherever possible. "The market is there," said Andrew White, co-founder of small production house Indie Studios. People "don't want to talk about how it's made", White pointed out. "That's inside baseball. People want to enjoy the movie because of the movie." But White himself refuses to adopt the technology, considering that using AI would compromise his creative process. Jamie Umpherson argues that AI allows creators to stick closer to their artistic vision than ever before, since it enables unlimited revisions, unlike the traditional system constrained by costs. "I see resistance everywhere" to this movement, observed Georgia State's Strickler. This is particularly true among her students, who are concerned about AI's massive energy and water consumption as well as the use of original works to train models, not to mention the social impact. But refusing to accept the shift is "kind of like having a business without having the Internet", she said. "You can try for a little while." In 2023, the American actors' union SAG-AFTRA secured concessions on the use of their image through AI. Strickler sees AI diminishing Hollywood's role as the arbiter of creation and taste, instead allowing more artists and creators to reach a significant audience. Runway's founders, who are as much trained artists as they are computer scientists, have gained an edge over their AI video rivals in film, television, and advertising. But they're already looking further ahead, considering expansion into augmented reality and virtual reality – for example creating a metaverse where films could be shot. "The most exciting applications aren't necessarily the ones that we have in mind," said Umpherson. "The ultimate goal is to see what artists do with technology." – AFP

Johnson & Johnson Launches VARIPULSE™ Platform across Asia-Pacific, Advancing Atrial Fibrillation Treatment
The VARIPULSE™ Platform is the first Pulsed Field Ablation (PFA) system fully integrated with the CARTO™ 3 electroanatomical mapping system, designed to drive efficiency, reproducibility, and procedural accuracy.1,i,ii,iii,iv,v,vi,vii,viii,ix The VARIPULSE™ Platform is approved in Japan, Hong Kong, China, Australia, Taiwan and Korea. IRVINE, Calif., July 8, 2025 /PRNewswire/ — Johnson & Johnson MedTech, a global leader in cardiac arrhythmia treatment, today announced the launch of the VARIPULSE™ Platform in Asia-Pacific. The platform is used to perform catheter ablation procedures for atrial fibrillation (AFib), an irregular and often rapid heartbeat caused by extra, uncoordinated electrical signals in the atria.x AFib is associated with structural changes in the heart due to underlying conditions and lifestyle factors.x,xi It significantly increases the risk of stroke, heart failure, and mortality. The VARIPULSE™ Platform is the first PFA technology designed to streamline ablation and mapping through a single integrated workflow with the CARTO™ 3 System. This 3D electroanatomical cardiac mapping technology enables real-time visualization and supports precision, efficiency, reproducibility, and procedural accuracy for physicians treating patients with atrial fibrillation (AFib)xii. It enables safe and efficienti,ii,iii,iv,v,vi,vii, patient-centric therapy with minimal to no fluoroscopy exposurexiii,xiv,xv and is compatible with deep and/or conscious sedation.2,xvi,xvii This innovation is backed by compelling clinical evidence. Both the inspIRE and admIRE clinical trials demonstrated strong safety and effectiveness of the VARIPULSE™ Platform: In inspIRE, 80% of patients achieved freedom from recurrence with zero primary adverse In admIRE, results showed a 75% overall primary effectiveness success rate3, a 2.9% primary adverse event rate4,xix, 100% of patients achieved acute procedural success5, 43% had same-day discharge, and 25% of procedures were performed without fluoroscopy6. In the ongoing VARIPURE registry, which included first-time users, there were no serious adverse events and no complications linked to the platform, including zero neurovascular events or coronary spasmsxx. 'The introduction of the VARIPULSE™ Platform in the Asia-Pacific region marks a significant advancement towards our goal of transforming atrial fibrillation care,' stated Jing Li, Vice President, Electrophysiology & Neurovascular, Johnson & Johnson MedTech, Asia Pacific. 'The adoption of the VARIPULSE™ Platform could demonstrate the unique value of integration with CARTO™ 3D to enhance efficiencies in the workflow of AFib treatment and improve patient outcomes.' Atrial Fibrillation affects over 16 million people in Asia-Pacificxxi. Symptoms and clinical consequences of AFib disrupt patient's quality of life. The most common symptoms are heart palpitations, fatigue, shortness of breath, chest pain, and dizzinessxxii. As a progressive condition, early intervention is critical to reducing the risk of stroke, heart failure, and cardiovascular mortalityxxiii. Unlike traditional ablation methods that use heat or cold, PFA uses short bursts of energy to affect heart tissue, potentially reducing the risk of damage to surrounding tissue such as the esophagus, pulmonary veins, and phrenic nerve. 'PFA, as a new type of energy, has the potential to further enhance the safety and efficacy of catheter ablation treatment, which is desirable for patients' said Dr. Yasuo Okumura7, Professor and Department Head, Vice Hospital Director, Nihon University School of Medicine, Itabashi Hospital, Tokyo, Japan. 'PFA is a relatively new medical technology, and therefore it is important to continue to assess its effectiveness and efficacy in Asia while ensuring proper use. But so far, we know that the integration of PFA technology with 3D mapping enables physicians to review their procedure in detail, and this contributes to quality of healthcare for patients.' About the VARIPULSE™ PlatformThe VARIPULSE™ Platform is Johnson & Johnson MedTech's Pulsed Field ablation system. The fully integrated platform includes the VARIPULSE™ Catheter, TRUPULSE™ Generator, and CARTO™ 3 Mapping System VARIPULSE™ Software.
