In medicine, a prosthesis, or a prosthetic implant, is an artificial device that replaces a missing body part, which may be lost through trauma, disease, or a condition present at birth. A pioneering project to develop advanced pressure sensors for use in robotic systems could transform prosthetics and robotic limbs. The innovative research project aspires to develop sensors that provide enhanced capabilities to robots, helping improve their motor skills and dexterity, through the use of highly accurate pressure sensors that provide haptic feedback and distributed touch.

It is led by the University of the West of Scotland (UWS), Integrated Graphene Ltd, and supported by the Scottish Research Partnership in Engineering (SRPe) and the National Manufacturing Institute for Scotland (NMIS) Industry Doctorate Programme in Advanced Manufacturing. This is not for the first time when the team of highly talented researchers have decided to bring the much needed transformative change in prosthetics and robotic limbs.

The human brain relies on a constant stream of tactile information to carry out basic tasks, like holding a cup of coffee. Yet some of the most advanced motorized limbs — including those controlled solely by a person’s thoughts — don’t provide this sort of feedback. As a result, even state-of-the-art prosthetics can often frustrate their users.

‘Tis all in the senses.

On her blog, Lepht Anonym describes herself as “a faceless, genderless British biohacker. It lacks both gods and money and likes people, science, and practical transhumanism.” Anonym practices, sometimes referred to as grinding — a subculture of biohacking — DIY surgery to insert electronic hardware under the skin.

At the Grinderfest in 2019, Anonym inserted a little “pirate box” device in her upper right arm.

For scientists searching for the brain’s ‘control room, an area called the claustrum has emerged as a compelling candidate. This little-studied deep brain structure is thought to be the place where multiple senses are brought together, attention is controlled, and consciousness arises. Observations in mice now support the role of the claustrum as a hub for coordinating activity across the brain. New research from the RIKEN Center for Brain Science (CBS) shows that slow-wave brain activity, a characteristic of sleep and resting states, is controlled by the claustrum. The synchronization of silent and active states across large parts of the brain by these slow waves could contribute to consciousness.

A serendipitous discovery actually led Yoshihiro Yoshihara, team leader at CBS, to investigate the claustrum. His lab normally studies the sense of smell and the detection of pheromones, but they chanced upon a genetically engineered mouse strain with a specific population of brain cells that was present only in the claustrum. These neurons could be turned on using optogenetic technology or selectively silenced through genetic manipulation, thus enabling the study of what turned out to be a vast, claustrum-controlled network. The study by Yoshihara and colleagues was published in Nature Neuroscience on May 11.

They started out by mapping the claustrum’s inputs and outputs and found that many higher-order brain areas send connections to the claustrum, such as those involved in sensation and motor control. Outgoing connections from the claustrum were broadly distributed across the brain, reaching numerous brain areas such as prefrontal, orbital, cingulate, motor, insular, and entorhinal cortices. “The claustrum is at the center of a widespread brain network, covering areas that are involved in cognitive processing,” says co-first author Kimiya Narikiyo. “It essentially reaches all higher brain areas and all types of neurons, making it a potential orchestrator of brain-wide activity.”

Living organisms offer extensive diversity in terms of their phenotypes, metabolic processes, and adaptation to various niches. However, the basic building blocks that create this diversity are remarkably similar. How can we advance our understanding of the fascinating mechanisms that drive biological complexity and how can we harness biological components to build entirely new materials and devices?

A new Special Issue from ACS Synthetic Biology will focus on this dynamic topic, including contributions that deconstruct as well as build up and mimic biological systems. The resulting work serves both to test our scientific understanding and to extend known biology to develop new concepts and applications. The issue will be led by Associate Editor Michael Jewett with Guest Editors Kate Adamala, Marileen Dogterom, and Neha Kamat.

A research team led by Rice University neuroengineers has created wireless technology to remotely activate specific brain circuits in fruit flies in under one second.

The team – an assemblage of experts in genetic engineering, nanotechnology, and electrical engineering – used magnetic signals to activate targeted neurons that controlled the body position of freely moving fruit flies in an enclosure.

New research from Binghamton University, State University of New York offers a second life for CDs: Turn them into flexible biosensors that are inexpensive and easy to manufacture.

In a paper published this month in Nature Communications, Matthew Brown, Ph.D. ‘22, and Assistant Professor Ahyeon Koh from the Department of Biomedical Engineering show how a gold CD’s thin metallic layer can be separated from the rigid plastic and fashioned into sensors to monitor electrical activity in human hearts and muscles as well as lactate, glucose, pH and oxygen levels. The sensors can communicate with a smartphone via Bluetooth.

The fabrication is completed in 20 to 30 minutes without releasing toxic chemicals or needing expensive equipment, and it costs about $1.50 per device. According to the paper, “this sustainable approach for upcycling electronic waste provides an advantageous research-based waste stream that does not require cutting-edge microfabrication facilities, expensive materials or high-caliber engineering skills.”

A scientific article just published by four Brazilian and two American scientists reports gains in electric and thermal energy obtained when brewer’s spent grain (barley bagasse), an abundant waste produced by the beer industry, is treated with ultrasound before undergoing anaerobic digestion, a microbiological process involving consumption of organic matter and production of methane.

Pre-treatment generated biogas with 56% methane, 27% more than the proportion obtained without use of ultrasound. After purification in methane, the biogas can be used as vehicle fuel with a very low carbon footprint compared to conventional fossil fuels. Moreover, in cogenerators, the methane can be burned off by the brewery to produce electricity and heat. The final waste can be used as biofertilizer instead of mineral fertilizer. The methodology is described in detail in the article, which is published in the Journal of Cleaner Production.

The innovative process was developed at the Laboratory of Bioengineering and Treatment of Water and Waste (Biotar) in the State University of Campinas’s School of Food Engineering (FEA-UNICAMP). The research group lead, T nia Forster-Carneiro, is principal investigator for a project supported by FAPESP.
