To fight stony coral tissue loss disease (SCTLD), which infects and kills corals already weakened by climate change, scientists are turning to antibiotics.

The landing mishap ended a string of 267 successful booster recoveries.

रोबोटिक्स के क्षेत्र में प्रगति को अनुसंधान से बढ़ावा मिलता है, जो बदले में रोबोट नियंत्रण और नेविगेशन के लिए एल्गोरिदम का परीक्षण करने के लिए प्रभावी प्लेटफार्मों पर बहुत अधिक निर्भर करता है।जबकि पिछले दशकों में कई रोबोटिक्स प्लेटफ़ॉर्म विकसित किए गए हैं, उनमें से अधिकांश में कमियां हैं जो अनुसंधान सेटिंग्स में उनके उपयोग को सीमित करती हैं।

Organic redox-active molecules (ORAMs) are abundant and diverse, offering significant potential for cost-effective and sustainable energy storage, particularly in aqueous organic flow batteries (AOFBs). However, ensuring the stability of the ORAMs during the charge and discharge process is critical, as side reactions can deactivate them and eliminate their redox activity. Air stability remains a challenge for many ORAMs, complicating their practical use.

Tokyo-Yokohama remains the world's largest science and technology cluster in 2024, though clusters in middle-income economies are seeing the fastest growth in the innovation sector, the United Nations said Tuesday.

SpaceX is waiting for better weather in the splashdown zone where the crew will end its five-day mission.

Amidst the ongoing energy crisis and under the threat of climate change, exploiting renewable energy sources has quickly become a global necessity. Though our options are varied, solar energy seems to be our best bet—experts estimate that it may become our main energy source well before the turn of the century.

The growing concerns about air pollution and its harmful effects on human health and climate change have led to increasingly stringent vehicular emission norms. These regulations have contributed to significant reductions in carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter from transportation sources. The European Union's Euro 7 standard, set to take effect in 2026, further tightens these limits by establishing a threshold for 10 nanometer particulate matter emissions and requiring low-temperature emissions testing at -7°C.

For self-flying aircraft to take to the skies, they need to learn about their environments to avoid hazards. NASA aeronautics researchers recently developed a camera pod with sensors to help with this challenge by advancing computer vision for autonomous aviation.

A sensor on the electric grid picks up a strange blip in current or voltage. What's happening, and will it cause an outage? Usually, a utility worker must travel in person to check. Researchers at the Department of Energy's Oak Ridge National Laboratory have now developed a new automated drone inspection system that can respond rapidly to unusual electric grid behavior, especially in remote areas that are tough for a worker to reach.

Roadway-related incidents are a leading cause of flood fatalities nationwide, but limited flood-reporting tools make it difficult to evaluate road conditions in real time.

Lithium-ion batteries are everywhere, in cell phones, computers, electric vehicles, and even toys, to name only a few places. They have become an integral part of our everyday lives.

Discourse relation classification is a fundamental task for discourse analysis, which is essential for understanding the structure and connection of texts. Implicit discourse relation classification aims to determine the relationship between adjacent sentences and is the most challenging in discourse relation classification because it lacks explicit discourse connectives as linguistic cues and sufficient annotated training data.

Plus, Bryce Dallas Howard has an unfortunate update about the Escape to Witch Mountain series.

The highest-resolution ground-based observations by the Event Horizon Telescope is paving the way for the future of black hole astronomy.

What makes structures and materials designed for extreme environments reliable? Research led by the University of Alabama at Birmingham and published in Scientific Reports details developments in the understanding of additively manufactured materials under high pressures through the use of high-resolution imaging and computer simulations.

A new novel high-level framework is set to improve efficiency in life cycle assessment. In a paper, appearing in Journal of Cleaner Production, the stakeholder-driven framework is applied to an aviation case study.

New research reveals that synchronized foot vibrations and posture significantly enhance virtual walking experiences for stationary observers, improving self-motion, walking sensation, and embodiment. Standing posture was most effective, but sitting and lying positions also benefited from synchronized vibrations. These findings have practical applications in virtual reality (VR) for training, rehabilitation, and entertainment, offering improved immersion and realism even for users with physical limitations.

Global Navigation Satellite System (GNSS) accuracy is crucial for precise applications, yet regional networks often face challenges in maintaining this precision. Integrating data from Low Earth Orbit (LEO) satellites with ground stations offers a promising solution to these challenges. Given these limitations, there is a clear need to explore more effective methods of GNSS orbit determination.

In May 2024, Russia launched a satellite that some observers believe is a weapon system that could allow the targeted destruction of other satellites in orbit.
