Asteroid’s unusual orbit hints at new type of heavenly object

Asteroids are common in our solar system, but astronomers have never seen one from outside the solar system, until now. Read More

Magnetic ‘magic’ offers a cool way to charge, cook

Charging a cellphone on an induction pad seems like magic, and in a way it is. Induction is a feature of electromagnetism that Michael Faraday stated in 1831, now known as Faraday’s law. It is the basis for much of modern electrical and electronic technology. Read More

Machines can be intelligent but they will never be human

Thinking machines are here, or not. The debate continues while developments in artificial intelligence create more and more sophisticated machines that are becoming more and more humanlike. Read More
