Trial passengers Sara Luchian and Josh Giegel – who both work at Virgin Hyperloop – inside their pod VIRGIN HYPERLOOP Virgin Hyperloop has trialled its first ever journey with passengers, in the desert of Nevada. The futuristic transport concept involves pods inside vacuum tubes carrying passengers at high speeds. In […]

The cruise phase began after the spacecraft separated from the rocket, soon after launch. The spacecraft departs Earth at a speed of about 24,600 mph (about 39,600 kph). The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). Credit: NASA/JPL-Caltech Headed to the […]

Titanium is used in knee and hip replacements. Monstar Studio/Shutterstock To mark the International Year of the Periodic Table of Chemical Elements we’re taking a look at how researchers study some of the elements in their work. Today’s it’s titanium, a metal known for its strength and lightness so it’s ideal for […]

Using ultrashort pulses of light enables extremely economical switching of a magnet from one stable orientation (red arrow) to another (white arrow). This concept enables ultrafast information storage with unprecedented energy efficiency.

The researchers studied how much fuel could be generated by installing a proposed new type of air conditioner at a landmark office building in downtown Frankfurt, Germany. (Credit: Bildgigant/shutterstock) In the hot and sticky suffocation of summer, air conditioners are a breezy balm. And as climate change heats Earth, the need for […]
