A national database containing images of ballistic markings from all new and imported guns sold in the U.S. should not be created at this time, says a new report from the National Research Council. Such a database has been proposed to help investigators link ballistics evidence -- cartridge cases or bullets found at crime scenes -- to a firearm and the location where it was originally sold.

But given the practical limitations of current technology for generating and comparing images of ballistic markings, searches of such an extensive database would likely produce too many candidate "matches" to be helpful, the report says.

Hardware piracy - making knock-off microchips based on stolen blueprints - has long been a chronic problem in the electronics industry. Computer engineers at the University of Michigan and Rice University have devised a comprehensive way to head off this costly infringement: Each chip would have its own unique lock and key. The patent holder would hold the keys. The chip would securely communicate with the patent-holder to unlock itself, and it could operate only after being unlocked.

The technique is called EPIC, short for Ending Piracy of Integrated Circuits. It relies on established cryptography methods and introduces subtle changes into the chip design process. But it does not affect the chips' performance or power consumption.

According to quantum mechanics, small magnetic objects called nanomagnets can exist in two distinct states (i.e. north pole up and north pole down). They can switch their state through a phenomenon called quantum tunneling.

When the nanomagnet switches its poles, the abrupt change in its magnetization can be observed with low-temperature magnetometry techniques used in del Barco’s lab. The switch is called quantum tunneling because it looks like a funnel cloud tunneling from one pole to another.

A new paper in Nature shows that two almost independent halves of a new magnetic molecule can tunnel, or switch poles, at once under certain conditions. In the process, they appear to cancel out quantum tunneling.
