When a fragrance wafted through the bedrooms of older adults for two hours every night for six months, memories skyrocketed. Participants in this study by University of California, Irvine neuroscientists reaped a 226% increase in cognitive capacity compared to the control group. The researchers say the finding transforms the long-known tie between smell and memory into an easy, non-invasive technique for strengthening memory and potentially deterring dementia.

The team’s study appears in Frontiers in Neuroscience. (Link to the open access study: https://www.frontiersin.org/articles/10.3389/fnins.2023.1200448/full).

The project was conducted through the UCI Center for the Neurobiology of Learning & Memory. It involved men and women aged 60 to 85 without memory impairment. All were given a diffuser and seven cartridges, each containing a single and different natural oil. People in the enriched group received full-strength cartridges. Control group participants were given the oils in tiny amounts. Participants put a different cartridge into their diffuser each evening prior to going to bed, and it activated for two hours as they slept.

Biofilms are highly resistant communities of bacteria that pose a major challenge in the treatment of infections. While studying biofilm formation in laboratory conditions has been extensively conducted, understanding their development in the complex environment of the human respiratory tract has remained elusive.

A team of researchers led by Alexandre Persat at EPFL have now cracked the problem by successfully developing organoids called AirGels. Organoids are miniature, self-organized 3D tissues grown from to mimic actual body tissues and organs in the human body. They represent a paradigm shift in the field, enabling scientists to replicate and study the intricate environments of organs in the laboratory.

Developed by Tamara Rossy and her colleagues, the AirGels are bioengineered models of human lung tissue that open up new possibilities in . They revolutionize research by accurately emulating the physiological properties of the airway mucosa, including mucus secretion and ciliary beating. This technology allows scientists to study airway infections in a more realistic and comprehensive manner, bridging the gap between in vitro studies and clinical observations.

Transparent electronic devices could have numerous valuable real-world applications. Among other things, they could enable the creation of new optical devices, smart gear or wearables, invisible solar panels and integrated communication systems.

Researchers at Xidian University, Southeast University and Wuhan University of Technology recently developed new, highly promising, transparent metadevices based on quasi-one-dimensional surface plasmon polariton (quasi-1D SPP) structures. These devices, introduced in a paper published in Nature Electronics, could be used to develop optically and radiofrequency transparent wireless and other .

“Transparent and invisible electronic is a fascinating goal that scientists and engineers are enthusiastically pursuing,” Prof. Bian Wu, one of the researchers who carried out the study, told Tech Xplore. “Currently, typically rely on the intrinsic properties of optically conductive materials, which are not radiofrequency transparent and have low operating efficiency. SSPs can be used to concentrate, channel and enhance energy. However, the use of SPPs in the development of optical and radiofrequency transparency remains blank.”

Meta’s new Twitter competitor, Threads, is looking for ways to keep users interested after more than half of the people who signed up for the text-based platform stopped actively using the app, Meta CEO Mark Zuckerberg reportedly told employees in a company town hall yesterday. Threads launched on July 5 and signed up over 100 million users in less than five days, buoyed by user frustration with Elon Musk-owned Twitter.

“Obviously, if you have more than 100 million people sign up, ideally it would be awesome if all of them or even half of them stuck around. We’re not there yet,” Zuckerberg told employees yesterday, according to Reuters, which listened to audio of the event.

Third-party data suggests that Threads may have lost many more than half of its active users. Daily active users for Threads on Android dropped from 49 million on July 7 to 23.6 million on July 14, and then to 12.6 million on July 23, web analytics company SimilarWeb reported.
