Introduced in the 1920s, toads on two islands in the Indian Ocean have shrunken limbs and bodies that may be evidence that "island dwarfism" can evolve quickly.

Fast and accurate fire detection is significant to the sustainable development of human society and Earth ecology. The existence of objects with similar characteristics to fire increases the difficulty of vision-based fire detection. Improving the accuracy of fire detection by digging deeper visual features of fire always remains challenging.

A team of researchers from the University of Chemistry and Technology Prague, Yonsei University and the Brno University of Technology has developed a micro-robot with chemically encoded intelligence that can remove hormonal pollutants from a solution. They have published their results in Nature Machine Intelligence. Dongdong Jin and Li Zhang with the Chinese University of Hong Kong and Multisca…

Video experiments show that monarch caterpillars turn aggressive when there’s not enough milkweed to go around.

Google said Thursday it will be rolling out end-to-end encryption for Android users, making it harder for anyone—including law enforcement—to read the content of messages.

In 1970, researchers saw a link between magnetic pole reversals and extinctions. Fifty years later, scientists have uncovered more suggestive examples but no strong evidence of a direct link.lamb

The vulnerability was found through the company's bug bounty program, now in its tenth year.

A new experiment used ultrafast techniques to reveal high-density water transforming into low-density water at subfreezing temperatures.

Emergencies, by their very nature, are hard to predict. When and where the next crime, fire or vehicle accident will happen is often a matter of random chance.

Increasingly, artificial intelligence systems known as deep learning neural networks are used to inform decisions vital to human health and safety, such as in autonomous driving or medical diagnosis. These networks are good at recognizing patterns in large, complex datasets to aid in decision-making. But how do we know they're correct? Alexander Amini and his colleagues at MIT and Harvard Unive…

Imagine if robots could learn from watching demonstrations: you could show a domestic robot how to do routine chores or set a dinner table. In the workplace, you could train robots like new employees, showing them how to perform many duties. On the road, your self-driving car could learn how to drive safely by watching you drive around your neighborhood.

The telescope, known for cameos in moves like Contact and for fast radio burst observations, was feared to be on the verge of collapse.
