New ‘camera’ with shutter speed of 1 trillionth of a second sees through dynamic disorder of atoms

Posted by in categories: particle physics, space, sustainability

Researchers are coming to understand that the best performing materials in sustainable energy applications, such as converting sunlight or waste heat to electricity, often use collective fluctuations of clusters of atoms within a much larger structure. This process is often referred to as “dynamic disorder.”

Understanding dynamic disorder in materials could lead to more energy-efficient thermoelectric devices, such as solid-state refrigerators and , and also to better recovery of useful energy from , such as car exhausts and power station exhausts, by converting it directly to electricity. A was able to take heat from radioactive plutonium and convert it to electricity to power the Mars Rover when there was not enough sunlight.

How big can animals get?

Animals, especially those on land, can’t grow indefinitely. The reason has to do with the square-cube law.

This Is What the End of the Universe Will Look Like, According to a Cosmologist

Posted by in categories: futurism, space

End of the universe would look like?


It’s difficult to speak of the far future of the universe with any level of precision, but we can make rough estimates. Our cosmos is currently 13.77 billion years old, and galaxies throughout the universe will continue making new stars for many years to come. But eventually—roughly one trillion years from now—the last star will be born.

That star will likely be a small red dwarf, barely a fraction of our sun’s mass. Red dwarf stars live fantastically long lives, gently sipping on hydrogen to power a slow but steady fusion reaction. But eventually, all stars, including the red dwarfs, will come to an end. In roughly 100 trillion years, the last light will go out.

WHAT happens When AI Becomes SELF-AWARE…

Posted by in categories: information science, robotics/AI

In recent years, the field of artificial intelligence has made tremendous strides, but what happens when #AI systems become #selfaware? In this video, we’ll explore the concept of AI self-awareness, its #scary implications for society, and what it means for the #future of AI.

AI self-awareness is the ability of an #artificialintelligence system to recognize its own existence and understand the consequences of its actions. While there are different levels of self-awareness that an AI system could potentially exhibit, it generally involves the system being able to recognize and respond to changes in its own state.
One way that researchers are exploring AI self-awareness is by using neural networks and other machine learning algorithms. For example, researchers have created AI systems that can recognize and respond to their own errors, which is an important first step in developing higher-order self-awareness.

Twisting stuff until it breaks — at the molecular level

Posted by in category: chemistry

Aromatic bonds, particularly strong chemical bonds which form in some ring-shaped molecules, are a crucial building block of the world around us. They appear in everything from proteins to aspirin, and literally millions of natural and synthetic substances in between.

The bonds are very hard to break and to control, and their properties have puzzled chemists for more than a century.

Which is just the motivation chemists needed to break and control them, and now a group of UK researchers has figured out how to twist an aromatic bond until it breaks.

“Organoid Intelligence” — Revolutionary Biocomputers Powered by Human Brain Cells

Posted by in categories: biotech/medical, robotics/AI

Despite AI’s impressive track record, its computational power pales in comparison with a human brain. Now, scientists unveil a revolutionary path to drive computing forward: organoid intelligence, where lab-grown brain organoids act as biological hardware.

Artificial intelligence (AI) has long been inspired by the human brain. This approach proved highly successful: AI boasts impressive achievements – from diagnosing medical conditions to composing poetry. Still, the original model continues to outperform machines in many ways. This is why, for example, we can ‘prove our humanity’ with trivial image tests online. What if instead of trying to make AI more brain-like, we went straight to the source?

Scientists across multiple disciplines are working to create revolutionary biocomputers where three-dimensional cultures of brain cells, called brain organoids, serve as biological hardware. They describe their roadmap for realizing this vision in the journal Frontiers in Science.

Is There Life on Mars? Artificial Intelligence Could Help Uncover Alien Life on Mars and Beyond

Posted by in categories: alien life, robotics/AI

Summary: Scientists have developed a way to use artificial intelligence (AI) to find signs of life on other planets. They combined statistical ecology and machine learning to map the patterns and rules of how life survives in harsh environments on Earth, and then trained the AI to recognize those same patterns and rules in data from other planets. This method can help guide rovers and other exploration missions to places with the highest probability of containing life.

Wouldn’t finding life on other worlds be easier if we knew exactly where to look? Researchers have limited opportunities to collect samples on Mars or elsewhere or access remote sensing instruments when hunting for life beyond Earth.
