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…

Houston team one step closer to growing capillaries

Researchers from Rice University and Baylor College of Medicine have shown they initiate a process called tubulogenesis that is crucial to the formation of blood-transporting capillaries. In microscopic images taken a different times during a weeklong experiment, researchers tracked the changes in cells (green) and cell nuclei (orange) using fluorescent markers.

High-reliability OCSP stapling and why it matters

At Cloudflare our focus is making the internet faster and more secure. Today we are announcing a new enhancement to our HTTPS service: High-Reliability OCSP stapling. This feature is a step towards enabling an important security feature on the web: certificate revocation checking. Reliable OCSP stapling also improves connection times by up to 30% in some cases. In this post, we’ll explore the importance of certificate revocation checking in HTTPS, the challenges involved in making it reliable, and how we…

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…

Study indicates concrete construction waste can help rid the air of sulfur dioxide, a major pollutant

This electron microscopy image of concrete includes a model of sulfur dioxide interactions with concrete surface – represented by the colored spheres. Credit: Marija Illoska New research reveals that sulfur dioxide, a major contributor to air pollution, is removed from the air by concrete surfaces. Stony Brook University researcher Alex Orlov, PhD, and colleagues discovered how concrete interacts and eliminates sulfur and nitrogen oxides. Their findings, published in the July edition of the Journal of Chemical Engineering, could be a…

Does the U. S. Need a New Star Wars Program?

On the Fourth of July last week, the world saw one rocket’s red glare that wasn’t fired in celebration:  North Korea launched the latest in a series of intercontinental ballistic missile (ICBM) tests.  The timing was intentional, and the North Korean news agency quoted its leader Kim Jong-un as saying, “The American bastards must be quite unhappy after watching our strategic decision.”  Not exactly diplomatic language.  Although the test missile went mostly straight up and down and landed harmlessly in…

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…

How Technology is Removing Hurdles of Higher Education

The world of education has dramatically changed. While some of the points taught are still the same, how you access information, prepare papers, and conduct your research has drastically changed because we live in a technology-centered world now. It seems like just a few years ago all you needed was your textbook, notes from class, and a good set of encyclopedias. If you gave an elementary student a set of encyclopedias to do his or her work, they might look…

Wiring a Thermometer to Your Van to Turn on AC as Needed as You Sleep » Curious Cat Science and Engineering Blog

Wiring a Thermometer to Your Van to Turn on AC as Needed as You Sleep Posted on July 8, 2017  Comments (0) You may well not be familiar with the growing vanlife community, but I learned of it and see it as an intriguing lifestyle possibility. It allows you to travel and stay in National Forest and BLM land for free (in the USA) and relatively cheaply at campgrounds etc.. People also live in them in cities while traveling stay…
