Protection against electromagnetic interference

Researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivaled in terms of weight.

Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic components or the transmission of signals. High-frequency electromagnetic fields can only be shielded with conductive shells that are closed on all sides...

Early findings indicate eating the fruit could help with skin allergies

In a study done with mice and published earlier this month in the journal Nutrients, researchers found that a diet high in black raspberries reduced inflammation from contact hypersensitivity – a condition that causes redness and inflammation in the skin.

“A lot of times, treatments are directly applied to the skin – things like steroids,” said Steve Oghumu, senior author on the paper and an assistant professor of pathology at The Ohio State University.

“And it was interesting that the mere consumption of a fruit can achieve the same effects.”

The researchers put a group of mice on a ...

A new approach in ophthalmology that offers a revolutionary alternative to corneal transplantation has just been developed by researchers and clinicians in North America, Europe, and Oceania. The team was co-led by May Griffith, a researcher at Maisonneuve-Rosemont Hospital Research Centre, which is affiliated with Université de Montréal and is part of the CIUSSS de l’Est-de-l’Île-de-Montréal.

The results of this multinational project have just been published in the journal Science Advances...

Researchers at Virginia Commonwealth University and the University of California, Los Angeles have made an important advance that could lead to more energy efficient magnetic memory storage components for computers and other devices.

Magnets are widely used for computer memory because their “up” or “down” polarity — the magnetic state — can be “flipped” to write or encode data and store information. Magnetic memory is nonvolatile, so information can be stored on devices without refreshing. However, magnetic memory also requires a lot of energy.

A recently discovered magnetic state called the skyrmion, which is neither “up” nor “down” but flower-shaped, offers a solution...
