Virus-cutting enzyme helps bacteria remember a threat

Bacteria may not have brains, but they do have memories, at least when it comes to viruses that attack them. Many bacteria have a molecular immune system which allows these microbes to capture and retain pieces of viral DNA ...

When electric fields make spins swirl

We are reaching the limits of silicon capabilities in terms of data storage density and speed of memory devices. One of the potential next-generation data storage elements is the magnetic skyrmion. A team at the Center for ...

How bacterial cell recognizes its own DNA

It may come as a bit of a surprise to learn that bacteria have an immune system - in their case to fight off invasive viruses called phages. And like any immune system - from single-celled to human - the first challenge of ...

How much netbook can you get for $400?

The hottest segment of the computer market right now is not fancy new Apple laptops or PC gaming machines. It's tiny laptops with older operating systems, cramped keyboards and designs that look like they might have come ...

Cost-saving computer chips get smaller than ever

Not so long ago, a computer filled a whole room and radio receivers were as big as washing machines. In recent decades, electronic devices have shrunk considerably in size and this trend is expected to continue, leading to ...

An electrical switch for magnetism (w/ Video)

Researchers at MIT have developed a new way of controlling the motion of magnetic domains—the key technology in magnetic memory systems, such as a computer's hard disk. The new approach requires little power to write and ...

Researchers develop data bus for quantum computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass ...
