If you want to maximize the number of trains that can operate on one line simultaneously, it's crucial that you know the exact location of each train at all times. A new system is designed to help, by analyzing the magnetic properties of the rails.

While it would be great if teachers could spend lots of time with each of their students, the fact is that children often end up doing most of their handwriting exercises unsupervised. A new system may help address that problem, using a "smart" pen.

A team in Germany has just taken an important step forward in energy storage research, demonstrating a lithium-metal battery with a remarkable energy density of 560 Wh/kg and an ability to retain its performance across hundreds of cycles.

E-waste is a growing problem, so if an electronic component can't be reused or recycled, it should at least be biodegradable. That's where an experimental new electronic display comes in, as it can be composted when no longer needed.

Estonia's Skeleton Technologies and Germany's Karlsruhe Institute of Technology have partnered up to complete development on what they're calling the SuperBattery for EVs – "a groundbreaking graphene battery with a 15-second charging time."

If you were heading into a burning building, you'd probably want someone else to know your location within it at all times. German scientists have developed a system that's said to serve that purpose, for use by firefighters and other rescue workers.

Bacteria that produce their own electricity could be useful in batteries, but so far, attempts have been inefficient. A new “biohybrid” system is built around a hydrogel and can support the microbes while effectively collecting their energy.

One argued silver lining of rising atmospheric carbon dioxide levels is that plants will be better off. But a new study has found that the more extreme heat and drought brought on by climate change would cancel out most of the benefits for trees.

While large 3D-printed objects such as buildings may get a lot of attention, the technology is also used to produce tiny, intricate objects. The latter could soon be whipped up faster and in more detail than ever, thanks to a new printing system.

The most common form of arthritis, arthrosis is caused by wear and tear on joint cartilage. And while some exercise helps, too much just makes things worse. That's where a new "smart" knee bandage will come in, by providing real-time strain readings.

With an ability to stiffen up under a certain type of light and go soft in the dark, a new dynamic material shows particular promise for the world of 3D printing, where it could be used as a temporary support for complex structures that melts away when the job is done.

It's not enough to just reduce our carbon dioxide emissions now – we need to remove some of what’s already in the atmosphere. Now, researchers at KIT have developed a simple way to turn the troublesome gas into a useful resource: by converting it into the “wonder” material graphene.
