In order to 3D-print really intricate items, you need a really fine print nozzle. Scientists have discovered that instead of going to the time and trouble of building one, you can simply repurpose a mosquito's existing blood-sucking proboscis.

Incorporating a phase-change material into concrete, this self-heating material can melt snow and ice for up to 10 hours without any help. The novel product could reduce the need for plowing and salting and help preserve the integrity of road surfaces.

Concrete may seem strong, but it can be surprisingly vulnerable to the elements. Now researchers at Drexel University have demonstrated a type of self-healing concrete embedded with “BioFibers” that use bacteria to patch up cracks as they form.

Engineers at Drexel University have made a breakthrough they say takes high-capacity lithium-sulfur batteries closer to commercial use, by leveraging a rare chemical phase of sulfur to prevent damaging chemical reactions.

Researchers at Drexel University have created “Faraday fabrics” that can block almost all electromagnetic waves. The key ingredient is a 2D material called MXene, and the development could help protect wearables from interference and people from potentially dangerous radiation.

Electromagnetic shielding is usually placed around electronics to prevent interference. Now, engineers have found that a 2D material called titanium carbonitride is excellent at the job, absorbing rather than reflecting electromagnetic waves.

​When calcium chloride de-icer is spread on sidewalks or roads, it reacts with the calcium hydroxide in concrete, creating calcium oxychloride. Also known as CAOXY, this substance expands within the concrete, causing it to crack. Adding bacteria, however, may keep that from happening.

As crucial as antennas are, the rigid metals they’re made of can limit what devices they can be built into. To help with that, researchers at Drexel University have developed a new kind of antenna that can be sprayed onto just about any surface.

Team DRC-HUBO, led in part by the HUBO Lab at the Korea Advanced Institute of Science and Technology (KAIST), reveals a robot that will compete in the upcoming DARPA Robotics Challenge.

A Drexel University team is studying how to extend the capabilities of UAVs by giving them robot arms and hands.

A scientist has created an automobile driver's side mirror that eliminates the blind spot, while creating almost no distortion.

Mathematician Andrew Hicks has used computer algorithms to generate a mirror that produces a mirror image that isn’t a mirror image, making it possible to read reflected text normally.
