Expandable Foam for 3D Printing Large Objects
It's a frustrating limitation of 3D printing: Printed objects must be smaller than the machine making them. Huge machines are impractical for printing large parts because they take up too much space and require excessive time to print. Now, a new material can be used to 3D print small objects that expand upon heating. The foam could find applications in architecture, aerospace and biomedicine.

New Chip Wakes Up Small Wireless Devices, Could Extend Battery Life
A new power saving chip developed by engineers could significantly reduce or eliminate the need to replace batteries in Internet of Things devices and wearables. The so-called wake-up receiver wakes up a device only when it needs to communicate and perform its function. It allows the device to stay dormant the rest of the time and reduce power use.
