Brain-computer interface technology opens up “whole new world” of therapies
Posted by Dan Breeden in categories: biotech/medical, computing, cyborgs, neuroscience
“We are starting to help patients in ways that we did not think were possible,” Thomas Oxley (Mount Sinai Hospital, New York, USA) tells NeuroNews, referring to the potential of brain-computer interface (BCI) technology. Alongside his role as a vascular and interventional neurologist, Oxley is chief executive officer of Synchron, developer of the Stentrode motor neuroprosthesis. The Stentrode is an implantable BCI device that, according to Oxley, is the first of its kind to be in the early feasibility clinical stage in the USA following US Food and Drug Administration (FDA) approval of Synchron’s investigational device exemption (IDE) application last month. Speaking to NeuroNewsfollowing a presentation on the topic at the Society of NeuroInterventional Surgery’s 18thannual meeting (SNIS; 26–29 July 2021, Colorado Springs, USA and virtual), Oxley gives an overview of the COMMAND early feasibility study, anticipates key results, and considers more generally how BCI technology could shape the future of deep brain stimulation.

New ‘FabricScape’ Bug in Microsoft Azure Service Fabric Impacts Linux Workloads
Posted by Saúl Morales Rodriguéz in category: computing
Researchers reveal details about a new vulnerability in Microsoft’s Service Fabric that could be exploited to gain elevated privileges on Linux.
At present, our brains are mostly dependent on all the stuff below the neck to turn thought into action. But advances in neuroscience are making it easier than ever to hook machines up to minds. See neuroscientists John Donoghue and Sheila Nirenberg, computer scientist Michel Maharbiz, and psychologist Gary Marcus discuss the cutting edge of brain-machine interactions in “Cells to Silicon: Your Brain in 2050,” part of the Big Ideas series at the 2014 World Science Festival.
This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

Blockchain not just for bitcoin. It can secure and store genomes too
Posted by Genevieve Klien in categories: biotech/medical, bitcoin, blockchains, chemistry, computing, cryptocurrencies
Blockchain is a digital technology that allows a secure and decentralized record of transactions that is increasingly used for everything from cryptocurrencies to artwork. But Yale researchers have found a new use for blockchain: they’ve leveraged the technology to give individuals control of their own genomes.
Their findings are published June 29 in the journal Genome Biology.
“Our primary goal is to give ownership of genomic data back to the individual,” said senior author Mark Gerstein, the Albert L. Williams Professor of Biomedical Informatics and professor of molecular biophysics and biochemistry, of computer science, and of statistics and data science.

Novel construction system uses acoustic levitation to assemble parts
Posted by Dan Breeden in categories: computing, particle physics
LeviPrint is a system that uses acoustic manipulation for assembling objects without physical contact. It generates acoustic fields that trap small particles, glue droplets and elongated stick-like elements that can be manipulated and reoriented as they are levitated. It is a fully functional system for manufacturing 3D structures using contactless manipulation.
It was developed by researchers from the UPNA/NUP-Public University of Navarre Asier Marzo and Iñigo Ezcurdia, who together with Rafael Morales (Ultraleap Ltd, UK) and Marco Andrade (University of São Paulo, Brazil) are authors of the paper “LeviPrint: Contactless Fabrication using Full Acoustic Trapping of Elongated Parts.”

Intel Silicon Photonics Breakthrough Paves Way For Lightspeed I/O And Chip Interconnects
Posted by Quinn Sena in categories: computing, innovation
Intel Labs has announced that it has made a noteworthy advancement in the area of integrated photonics research, which it bills as the “next frontier” in expanding communications bandwidth between compute silicon in data centers and across networks. The company believes this advancement holds the promise of a future input/output (I/O) interface with improved energy efficiency and bandwidth, and a longer reach.
The disclosure explains the possibility to obtain well-matched output power in conjunction with uniform and densely spaced wavelengths, according to Haisheng Rong, Senior Principal Engineer at Intel Labs. Rong also points out that this can be done by utilizing existing manufacturing and process techniques in Intel fabs, and therefore ensures a path to volume production of the “next-generation co-packaged optics and optical compute interconnect at scale.”
Intel states that this breakthrough results in industry-leading advancements in multiwavelength integrated optics. It includes the demonstration of an eight-wavelength distributed feedback (DFB) laser array that is fully integrated on a silicon wafer and provides exceptional output power uniformity of +/-0.25 decibel (db), as well as wavelength spacing uniformity of +/-6.5% that go beyond industry specifications.
