A growing portion of Americans who are struggling to pay for their household energy live in the South and Southwest, reflecting a climate-driven shift away from heating needs and toward air conditioning use, an MIT study finds.

For long periods of its history, artificial intelligence has lurked in the hinterland of science, often unloved and unfunded—but two Nobel prizes in one week suggest its time in the sunshine has finally arrived.

Industries such as chemical manufacturing, fertilizer production and hydrogen generation could significantly cut emissions, improve efficiency and lower costs using a newly developed electrified reactor as an alternative to high-temperature industrial processes.

Researchers have created a new modeling tool that can be used to help develop ocean-based hydrokinetic energy projects. The tool can be used both to help design more robust marine hydrokinetic technologies and to inform risk assessments that are essential for securing financing and permitting of commercial projects. The paper, "Bayesian Modeling and Mechanical Simulations for Fragility Curve Estimation of The Mooring System of Marine Hydrokinetic Devices," is published in the journal Applied Ocean Research.

As pedestrian fatalities in the United States reach a 40-year high, a novel approach to measuring crosswalk lengths across entire cities could provide urban planners with crucial data to improve safety interventions.

British-Canadian Geoffrey Hinton and American John Hopfield won the Nobel physics prize on Tuesday for their pioneering work on the foundations of artificial intelligence, with both sounding the alarm over the technology they helped bring to life.

A new paper from the University of California San Diego details how China faces numerous political, economic and technological obstacles as it tries to transition away from coal—the country's primary energy source—while balancing the need to combat climate change with the need for energy security.

MIT engineers have built a new desalination system that runs with the rhythms of the sun. The researchers report details of the new system in a paper appearing in Nature Water.

Geoffrey Hinton, known as the Godfather of AI, and physicist John Hopfield won the Nobel physics prize on Tuesday for their pioneering work on the foundations of artificial intelligence.

In 1884, marine engineer Charles Parson used coal to power his groundbreaking invention, the multi-stage steam turbine, to produce electricity. This technological revolution marked a new dawn of power generation and consumption around the world. Today, humanity's increasing electricity and power needs require more efficient turbines and environmentally friendly fuels.

The Nobel Prize in Physics was awarded to two scientists on Tuesday for discoveries that laid the groundwork for the artificial intelligence used by hugely popular tools such as ChatGPT.

Researchers at Concordia have developed a novel method of 3D printing that uses acoustic holograms. And they say it's quicker than existing methods and capable of making more complex objects.

The National Renewable Energy Laboratory (NREL) has developed a first-of-its-kind tool that enables hydropower operators and developers to estimate the greenhouse gas emissions associated with building and operating closed-loop pumped storage hydropower (PSH) facilities.

The 2024 Nobel Prize in Physics has been awarded to scientists John Hopfield and Geoffrey Hinton "for foundational discoveries and inventions that enable machine learning with artificial neural networks."

फ़िनलैंड में टाम्परे विश्वविद्यालय और चीन में अनहुई जियानझू विश्वविद्यालय के शोधकर्ताओं ने सॉफ्ट रोबोटिक्स में एक महत्वपूर्ण सफलता हासिल की है।उनके अध्ययन में पहला टॉरॉयडल, प्रकाश-चालित माइक्रो-रोबोट पेश किया गया है जो बलगम जैसे चिपचिपे तरल पदार्थों में स्वायत्त रूप से चल सकता है।यह नवाचार चिकित्सा और पर्यावरण निगरानी जैसे क्षेत्रों में आशाजनक अनुप्रयोगों के साथ, जटिल वातावरण को नेविगेट करने में सक्षम सूक्ष्म रोबोट विकसित करने की दिशा में एक बड़ा कदम है।

Engineers have worked out how to give robots complex instructions without electricity for the first time, which could free up more space in the robotic 'brain' for them to 'think.'

समुद्री ऊर्जा उपकरणों में भारी मात्रा में बिजली प्रदान करने की क्षमता होती है - यदि वे समुद्र की दंडनीय स्थितियों से बच सकते हैं।तरंगों की गति को बिजली में परिवर्तित करने के लिए नवोन्वेषी सिस्टम डिज़ाइन की आवश्यकता होती है, लेकिन समुद्र विशाल और जटिल है, और इन दूरस्थ स्थानों में तैनाती महंगी है।

पूरे घर मिट्टी या खोदी गई मिट्टी से बनाए जा सकते हैं।यह सामग्री सस्ती, प्रचुर और टिकाऊ है क्योंकि इसमें सीमेंट की आवश्यकता नहीं होती है।हालाँकि, मौजूदा निर्माण विधियाँ बहुत श्रम-गहन, धीमी और इसलिए महंगी हैं।

जैसे ही तूफान मिल्टन फ्लोरिडा के खाड़ी तट की ओर अपने रास्ते पर तेज हुआ, सिस्टम की ताकत ने तूफान के पूर्वानुमान की गंभीरता को बढ़ा दिया।

दक्षिण अफ़्रीका जीवाश्म ईंधन-आधारित ऊर्जा प्रणाली से स्वच्छ, कम-कार्बन ऊर्जा प्रणाली में "उचित ऊर्जा संक्रमण" में डूबा हुआ है।यह नई प्रणाली मुख्य रूप से सौर, पवन और हरित हाइड्रोजन जैसी नवीकरणीय ऊर्जा पर आधारित होगी।
