Researchers create robot that smiles back

While our facial expressions play a huge role in building trust, most robots still sport the blank and static visage of a professional poker player. With the increasing use of robots in locations where robots and humans need ...

Software

Team builds first hacker-resistant cloud software system

Whenever you buy something on Amazon, your customer data is automatically updated and stored on thousands of virtual machines in the cloud. For businesses like Amazon, ensuring the safety and security of the data of its millions ...

Deep learning networks prefer the human voice—just like us

The digital revolution is built on a foundation of invisible 1s and 0s called bits. As decades pass, and more and more of the world's information and knowledge morph into streams of 1s and 0s, the notion that computers prefer ...

Software

New tool detects unsafe security practices in Android apps

Computer scientists at Columbia Engineering have shown for the first time that it is possible to analyze how thousands of Android apps use cryptography without needing to have the apps' actual codes. The team's new tool, ...

Energy & Green Tech

New technique extends next-generation lithium metal batteries

Electric vehicles (EVs) hold great promise for our energy-efficient, sustainable future but among their limitations is the lack of a long-lasting, high energy density battery that reduces the need to fuel up on long-haul ...

Laser inversion enables multi-materials 3-D printing

Additive manufacturing—or 3-D printing—uses digital manufacturing processes to fabricate components that are light, strong, and require no special tooling to produce. Over the past decade, the field has experienced staggering ...

Electronics & Semiconductors

'One-way' electronic devices enter the mainstream

Waves, whether they are light waves, sound waves, or any other kind, travel in the same manner in forward and reverse directions—this is known as the principle of reciprocity. If we could route waves in one direction only—breaking ...
