Trial drug can significantly block early stages of COVID-19 in engineered human tissues — ScienceDaily

An international team led by University of British Columbia researcher Dr. Josef Penninger has found a trial drug that effectively blocks the cellular door SARS-CoV-2 uses to infect its hosts. The findings, published today in Cell, hold promise as a treatment capable of stopping early infection of the novel coronavirus that, as of April 2, has affected more than 981,000 people and claimed the lives of 50,000 people worldwide. The study provides new insights into key aspects of SARS-CoV-2, the…

Bringing 4K and HDR to Anime at Netflix with Sol Levante

For the character design phase, animator Hisashi Ezura spent lots of time adjusting the thickness of the line because of the wider dynamic range. Having an outline on characters is unique in anime, but using the typical line thickness for SDR became too sharp and looked fake in HDR. He adjusted the pen pressure to have a bit softer touch than usual. A test image to check line thickness In the color design phase, the team initially thought 300 nits…

Understanding how the protein tau moves between neurons yields insight into possible treatments for neurodegenerative diseases — ScienceDaily

In the fight against neurodegenerative diseases such as frontotemporal dementia, Alzheimer’s and Chronic Traumatic Encephalopathy, the tau protein is a major culprit. Found abundantly in our brain cells, tau is normally a team player — it maintains structure and stability within neurons, and it helps with transport of nutrients from one part of the cell to another. All that changes when tau misfolds. It becomes sticky and insoluble, aggregating and forming neurofibrillary tangles within neurons, disrupting their function and ultimately…

Introducing 1.1.1.1 for Families

Two years ago today we announced 1.1.1.1, a secure, fast, privacy-first DNS resolver free for anyone to use. In those two years, 1.1.1.1 has grown beyond our wildest imagination.

Specialized Parts You Need for 5G

The Internet of Things (IoT) provides amazing possibilities for product development and is accelerating innovation at perhaps the fastest rate in history. However, while manufacturers are eager to go to market with IoT products, building appropriate security measures into these devices and communicating that due diligence to the marketplace often remains an afterthought. In this Q&A, Senior Editor Bill Wong talks with Andrew Jamieson, Director of Security and Technology at Underwriters Laboratories (UL) about how UL’s IoT Security Rating helps…

Announcing the Results of the 1.1.1.1 Public DNS Resolver Privacy Examination

On April 1, 2018, we took a big step toward improving Internet privacy and security with the launch of the 1.1.1.1 public DNS resolver — the Internet’s fastest, privacy-first public DNS resolver. And we really meant privacy first. We were not satisfied with the status quo and believed that secure DNS resolution with transparent privacy practices should be the new normal. So we committed to our public resolver users that we would not retain any personal data about requests made…

U.S. Chip Industry Lobbying to Stay Open Despite Virus Fears

The U.S. semiconductor industry is lobbying federal and state governments to have chip production plants labeled as essential businesses that are allowed to operate despite lockdowns to contain the spread of the novel coronavirus. The Semiconductor Industry Association (SIA), a top trade group representing the sector, is trying to lift its chances for exemptions to orders in states around the U.S. to close nonessential businesses. The group, which represents U.S. chip manufacturers from Intel and Texas Instruments to Micron Technology…

Addressing the Commercial Roots of the Consumer IoT Security Problem

Download this article in PDF format. To prevent counterfeit devices from joining a network or to limit the opportunity for network attacks, it’s important to authenticate devices attempting to join Internet of Things (IoT) networks and subsequently connect only authorized devices. The standard mechanism to securely authenticate clients connecting to a server is transport-layer-security (TLS) client-side authentication. To implement such authentication in an IoT network, the appropriate certificate authority (CA)—usually the IoT device provider—issues a unique X.509 certificate to each…
