Low-cost smart glove wirelessly translates the American Sign Language alphabet into text

Overview of the gesture-decoding glove. Credit: Timothy O’Connor et al (2017) A glove fitted with wearable electronics can translate the American Sign Language alphabet and then wirelessly transmit the text for display on electronic devices—all for less than $100, according to a study published July 12, 2017 in the open-access journal PLOS ONE by Timothy O’Connor and Darren Lipomi from University of California, San Diego, US, and colleagues. Current methods for tracking human body positions include cameras as well as…

Drones get to grips with planning the delivery of goods

When goods are needed urgently, for instance, in rural areas poorly served by transport infrastructure, or in large, heavily congested cities, they could be delivered by drones. In 2013, Amazon was one of the first to declare the intention to work towards the automated delivery of goods by small autonomous helicopters. A multi-disciplinary research team at the Alpen-Adria-Universität assembled by Christian Bettstetter and Friederike Wall is due to deliver initial insights on the efficient operation of (self-organised) delivery of goods.…

Design can control color, intensity of light by varying cavity architecture — ScienceDaily

From checkout counters at supermarkets to light shows at concerts, lasers are everywhere, and they’re a much more efficient light source than incandescent bulbs. But they’re not cheap to produce. A new Northwestern University study has engineered a more cost-effective laser design that outputs multi-color lasing and offers a step forward in chip-based lasers and miniaturization. The findings could allow encrypted, encoded, redundant and faster information flow in optical fibers, as well as multi-color medical imaging of diseased tissue in…

A new system to estimate the duration of a walk in the countryside

Left to right are, José Ignacio Álvarez Francoso, Joaquín Márquez Pérez and Ismael Vallejo Villalta. Credit: University of Seville Researchers from the department of Physical Geography and Regional Geographical Analysis at the University of Seville have developed a new system to estimate the time that it takes to do a walk in the countryside. It is an algorithm that takes into account length and gradient as the main variables when establishing how long a walk takes. After applying their method…

New study describes method to save lives in chemical attacks

A new study by Kiran Bhaganagar, associate professor of mechanical engineering at The University of Texas at San Antonio, and her research group, Laboratory of Turbulence Sensing & Intelligence Systems, is taking a closer look at the damage caused by chemical attacks in Syria. The Syrian Civil War, ongoing since 2011, has seen hundreds of people killed through the use of chemical weapons. Chemical agents are different from explosive chemicals, which cause localized destruction through force. Sarin gas, for example,…

Glioblastoma ‘ecosystem’ redefined for more effective immunotherapy trials — ScienceDaily

A research team has revealed the intrinsic gene expression patterns of glioblastoma (GBM) tumors, insights that could drive more effective treatments for GBM, the most common and deadly malignant primary brain tumors in adults. Jackson Laboratory (JAX) Professor Roel Verhaak, Ph.D., is the senior author of a paper published in Cancer Cell showing tumor gene expression patterns distinct from those of the surrounding immune cells, and characterizing the effects of chemotherapy and radiation treatments. Verhaak was the first author of…

Researchers revolutionize brain-computer interfaces using silicon electronics

A flexible multielectrode array designed by Shepard and his team. If successful, this noninvasive device could alter the lives of people with hearing and visual impairments and neurodegenerative diseases. Credit: Ken Shepard Today, implanted electrode devices for stimulating the brain are extremely crude devices with only a handful of electrodes that are used to mitigate the effects of Parkinson’s, epilepsy, and other neurodegenerative conditions. The number of patients with these devices is merely tens of thousands because of the extreme…

Detecting short circuits by going back in time

Credit: Murielle Gerber – 2017 EPFL It took EPFL researchers only three minutes to detect and locate a short circuit triggered intentionally in the power grid serving Fribourg Canton. The researchers, using a computer and a single sensor, spotted it by “going back in time” to find the origin of the problem. Their highly promising method could make it easier to manage complicated power grids, especially those incorporating renewable energies. Swiss power utility Groupe E agreed to trigger a short…

Participate in the Net Neutrality Day of Action

We at Cloudflare strongly believe in network neutrality, the principle that networks should not discriminate against content that passes through them.  We’ve previously posted on our views on net neutrality and the role of the FCC here and here. In May, the FCC took a first step toward revoking bright-line rules it put in place in 2015 to require ISPs to treat all web content equally. The FCC is seeking public comment on its proposal to eliminate the legal underpinning of…
