Researchers have invented a new technology that can drastically downsize the apparatus used for Raman spectroscopy, a well-known technique that uses light to identify the molecular makeup of compounds.

Researchers have developed a groundbreaking process for multi-material 3D printing of lifelike models of the heart's aortic valve and the surrounding structures that mimic the exact look and feel of a real patient.

A new study shows how two responses in separate locations inside plant cells work in concert to help corn plants respond to heat stress. The research was made possible by the Enviratron, an innovative plant sciences facility at Iowa State University that utilizes a robotic rover and highly controlled growth chambers.

Researchers working with tungsten to armor the inside of future fusion reactors had some surprising results when looking at the probability of contamination.

Researchers have revealed a new molecular mechanism by which bacteria adhere to cellulose fibers in the human gut. Thanks to two different binding modes, they can withstand the shear forces in the body.

A surface displays structural colors when light is reflected by tiny, regular structural elements in a transparent material. Researchers have now developed a method to make structural colors from cellulose-based polymers by using coated droplets that exist in a surrounding fluid -- so-called liquid marbles. The system readily responds to environmental changes, which makes it interesting for applications in bio-based sensors and soft photonic elements, according to a new study.

In order to kill diseased cells, our immune system must first identify them. The so-called peptide-loading complex plays a key role in this process. A research team has analyzed this nanomachine in atomic detail.

A stretchable, wearable gas sensor for environmental sensing has been developed and tested.

It wasn't long after Hurricane Laura hit the Gulf Coast Thursday that people began flying drones to record the damage and posting videos on social media. Those videos are a precious resource, say researchers who are working on ways to use them for rapid damage assessment. By using artificial intelligence, the researchers are developing a system that can automatically identify buildings and make an initial determination of whether they are damaged and how serious that damage might be.

Electrical engineers have created the smallest electro-optical modulator yet, using a thin film of lithium niobate bonded on a silicon dioxide layer. This key component of a photonics-based chip controls how light moves through its circuits and has broad applications in data communication, microwave photonics, and quantum photonics.

A new study found that teen drivers and drivers 65 years and older - two age groups at a higher risk of being involved in an automobile accident - are more likely to be driving vehicles that are less safe, putting them at even higher risk of injury. The findings underscore the need for these groups to prioritize driving the safest vehicle they can afford.
