Support CleanTechnica’s work through a Substack subscription or on Stripe. Or support our Kickstarter campaign! The Supreme Court’s decision limiting presidential tariff authority should have reduced uncertainty. Instead, it introduced a new layer of it. The Court narrowed the use of one statute for imposing broad tariffs. The response from the administration was immediate. Tariffs would continue under other authorities, and tariffs already collected would not be refunded. For capital markets, that sequence does not resolve risk. It shifts it. Clean technology deployment sits directly in the path of that shift because it is capital intensive, supply chain…

I’m using Expo SDK 54. In iOS when I use expo-router/unstable-native-tabes we cant wrap with another component. AppHeader should to go the page top. This breaks in iOS 26. How can we put this on every page top? import { useEffect } from ‘react’ import { Platform } from ‘react-native’ import { useAuth } from ‘@/context/AuthContext’ import { useRouter, Stack, usePathname } from ‘expo-router’ import { NativeTabs, Icon, Label, Badge } from ‘expo-router/unstable-native-tabs’ import MaterialIcons from ‘@expo/vector-icons/MaterialIcons’ import DashboardLayout from ‘@/components/layouts/DashboardLayout’ import AppHeader from ‘@/components/ui/header’ export default function ProtectedLayout() { const pathname = usePathname() const router = useRouter() const {…

After announcing the preview of managed integrations for AWS IoT Device Management on March 3rd, 2025, we are excited to share that the capability is now generally available, enabling developers to streamline cloud onboarding of IoT devices and unify device control across multiple brands and protocols. While IoT technology has been widely used in consumer and commercial applications, especially smart homes, fragmentation remains a major challenge. Users continue to face problems with incompatible devices, diverse protocols, and separate control systems that create interoperability barriers. To address these challenges, AWS IoT Device Management now offers managed integrations that include cloud and device…

Posted by Shai Barack, Android Platform Performance Lead and Charles Munger, Principal Software EngineerIn Android 17, apps targeting SDK 37 or higher will receive a new implementation of MessageQueue where the implementation is lock-free. The new implementation improves performance and reduces missed frames, but may break clients that reflect on MessageQueue private fields and methods. To learn more about the behavior change and how you can mitigate impact, check out the MessageQueue behavior change documentation. This technical blog post provides an overview of the MessageQueue rearchitecture and how you can analyze lock contention issues using Perfetto.The Looper drives the UI…

Antiracist economist Kim Crayton says that “intention without strategy is chaos.” We’ve discussed how our biases, assumptions, and inattention toward marginalized and vulnerable groups lead to dangerous and unethical tech—but what, specifically, do we need to do to fix it? The intention to make our tech safer is not enough; we need a strategy. Article Continues Below This chapter will equip you with that plan of action. It covers how to integrate safety principles into your design work in order to create tech that’s safe, how to convince your stakeholders that this work is necessary, and how to respond to…

The technology industry is obsessed with the future. Many of our modern marvels are rooted in the legacy of Bell Labs, an innovation powerhouse in suburban New Jersey. Bell Labs, the once-famed research arm of AT&T, celebrated the centennial of its founding last year.In its heyday, starting in the 1940s, the lab created a cascade of inventions, including the transistor, information theory and an enduring computer software language. The labs’ digital DNA is in our smartphones, social media and chatbot conversations.“Every hour of your day has a bit of Bell Labs in it,” observed Jon Gertner, author of “The Idea…

South East Technological University (SETU) is coordinating AM-Heal, a two-year, €400,000 Erasmus+ partnership designed to strengthen Additive Manufacturing (AM) skills for healthcare and rehabilitation. Working with partners in Spain, Malta, and Ukraine, SETU is leading AM-Heal to develop and deliver a Level 9 Micro-Credential, which will build digital skills and professional competencies at the intersection of AM and rehabilitation. The programme will be delivered through a blended approach, combining online learning via a multilingual e-learning platform with hands-on training in partner facilities. A dedicated 3D printing training hub in Kyiv will also be established to strengthen local capacity and support…

Large language models (LLMs) have been championed as tools that could democratize access to information worldwide, offering knowledge in a user-friendly interface regardless of a person’s background or location. However, new research from MIT’s Center for Constructive Communication (CCC) suggests these artificial intelligence systems may actually perform worse for the very users who could most benefit from them.A study conducted by researchers at CCC, which is based at the MIT Media Lab, found that state-of-the-art AI chatbots — including OpenAI’s GPT-4, Anthropic’s Claude 3 Opus, and Meta’s Llama 3 — sometimes provide less-accurate and less-truthful responses to users who have…

Today, we’re announcing the general availability of Amazon Elastic Compute Cloud (Amazon EC2) Hpc8a instances, a new high performance computing (HPC) optimized instance type powered by latest 5th Generation AMD EPYC processors with a maximum frequency of up to 4.5 GHz. These instances are ideal for compute-intensive tightly coupled HPC workloads, including computational fluid dynamics, simulations for faster design iterations, high-resolution weather modeling within tight operational windows, and complex crash simulations that require rapid time-to-results. The new Hpc8a instances deliver up to 40% higher performance, 42% greater memory bandwidth, and up to 25% better price-performance compared to previous generation Hpc7a…
