Ikea curtains break down pollutants, highlight interest in fabric purifiers

Can you use textiles to clean the air? Take sunlight. Add a film coating to fabric. And you get curtains that destroy pollutants and purify the air inside your home. The recipe is being touted by Ikea. Along with bunk beds and bedside tables, some thinkers at Ikea have been looking into technologies that can address indoor air pollution without having to resort to more complex filtering systems or electric power.

Recognizing disease using less data

As artificial intelligence systems learn to better recognize and classify images, they are becoming highly-reliable at diagnosing diseases, such as skin cancer, from medical images. But as good as they are at detecting patterns, AI won't be replacing your doctor any time soon. Even when used as a tool, image recognition systems still require an expert to label the data, and a lot of data at that: it needs images of both healthy patients and sick patients. The algorithm finds patterns in the training data and when it receives new data, it uses what it has learned to identify the new image.

Researchers invent a needle that knows where to go

Syringes and hollow needles have been used to deliver medication for more than a century. However, the precise implementation of these devices depends on the operator, and it can be difficult to deliver medication to delicate regions such as the suprachoroidal space at the back of the eye. Investigators from Brigham and Women's Hospital have developed a highly sensitive intelligent-injector for tissue-targeting (i2T2) that detects changes in resistance in order to properly and safely deliver medication in preclinical testing. Their results are published in Nature Biomedical Engineering.

Foldable phone outlook hinges on price

Handset makers are racing to launch their first smartphones with folding screens but analysts warn the technology is still too rudimentary—and expensive—to woo consumers in large numbers for now.

Online shopping algorithms are colluding to keep prices high

Have you ever searched for a product online in the morning and gone back to look at it again in the evening only to find the price has changed? In which case you may have been subject to the retailer's pricing algorithm.

Can we address climate change without sacrificing water quality?

Strategies for limiting climate change must take into account their potential impact on water quality through nutrient overload, according to a new study from Carnegie's Eva Sinha and Anna Michalak published by Nature Communications. Some efforts at reducing carbon emissions could actually increase the risk of water quality impairments, they found.

Researchers succeed in controlling extremely short-wavelength spin waves

In recent years, electronic data processing has been evolving in one direction only: The industry has downsized its components to the nanometer range. But this process is now reaching its physical limits. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) are therefore exploring spin waves, or so-called magnons—a promising alternative for transporting information in more compact microchips. Cooperating with international partners, they have successfully generated and controlled extremely short-wavelength spin waves. The physicists achieved this feat by harnessing a natural magnetic phenomenon, as they explain in the journal Nature Nanotechnology.
