Researchers on DARPA’s Brandeis Program Enhance Privacy Protections for Android Applications

Posted by in categories: finance, mobile phones

From navigation to remote banking, mobile device users rely on a variety of applications to streamline daily tasks, communicate, and dramatically increase productivity. While exceedingly useful, the ecosystem of third-party applications utilizes a number of sensors – microphones, GPS, pedometers, cameras – and user interactions to collect data used to enable functionality. Troves of sensitive personal data about users are accessible to these applications and as defense and commercial mobile device users become increasingly reliant on the technology, there are growing concerns around the challenge this creates for preserving user privacy.

Under DARPA’s Brandeis program, a team of researchers led by Two Six Labs and Raytheon BBN Technologies have developed a platform called Privacy Enhancements for Android (PE for Android) to explore more expressive concepts in regulating access to private information on mobile devices. PE for Android seeks to create an extensible privacy system that abstracts away the details of various privacy-preserving technologies, allowing application developers to utilize state-of-the-art privacy techniques, such as secure multi-party computation and differential privacy, without knowledge of their underlying esoteric technologies. Importantly, PE for Android allows mobile device users to take ownership of their private information by presenting them with more intuitive controls and permission enforcement options.

The researchers behind PE for Android today released a white paper detailing the platform’s capabilities and functionality, and published an open source release of its code to GitHub. In open sourcing PE for Android, the researchers aim to make it easier for the open-source Android community and researchers to employ enhanced privacy-preserving technologies within Android apps while also encouraging them to help address the platform’s current limitations and build upon its initial efforts.

Two Studies Just Revealed How Twisted Graphene Gets Even Weirder at a ‘Magic Angle’

Posted by in categories: computing, quantum physics

Graphene has already proven itself to be a weird and wonderful material in many different ways, but its properties get even more unusual and exotic when it’s twisted – and two new studies have given scientists a much closer look at this intriguing phenomenon.

When two sheets of graphene are put together at slightly different angles, the resulting material becomes either very effective at conducting electricity, or very effective at blocking it. It’s known as ‘magic-angle’ twisted graphene, and knowing more about how and why this happens could lead to advances in high-temperature superconductors and quantum computing.

Now for the first time, scientists have mapped out a twisted graphene structure in its entirety, and at a very high resolution. They’ve also been able to get ‘graphene twistronics’ working with four layers of graphene as well as just two.

Behavioral biometrics and continuous authentication advance as business adapts to remote everything

Posted by in categories: biotech/medical, business, privacy, security

Even as dramatic social change has been imposed by COVID-19, the kinds of fraud attacks companies experience and the biometric authentication technologies they use to prevent them have remained basically the same. What has changed is that online volumes of traffic, transactions and authentications have reached levels they were expected to years in the future, BehavioSec VP of Products Jordan Blake told Biometric Update in an interview.

As a result, he says, “timelines are getting advanced.”

Demand is coming from new verticals, according to Blake, as numerous people begin using the online channel to interact with many organizations they never have dealt with that way before.

Why investing in identity access management is a must-do in a time of remote working

This is a guest post by Shahrokh Shahidzadeh, CEO at Acceptto

These past two months have been among the most extraordinary times any of us can remember. The COVID-19 (CV-19) impact is all around us, indiscriminately impacting all of our lives, our work, the economy and for sure we are on the onset of a new normal that we are learning how to deal with daily.

There are always two stages of dealing with a change of this magnitude. First, we react immediately, thinking about what we must do differently now. Soon, we will begin to think in the longer term, reacting to and planning for permanent changes that result from the CV-19 pandemic.

Morpheus: Powerful New AI Technique Detects and Classifies Astronomical Objects

Posted by in categories: robotics/AI, space

UCSC researchers developed a deep-learning framework called Morpheus to perform pixel-level morphological classifications of objects in astronomical images.

Researchers at UC Santa Cruz have developed a powerful new computer program called Morpheus that can analyze astronomical image data pixel by pixel to identify and classify all of the galaxies and stars in large data sets from astronomy surveys.

Morpheus is a deep-learning framework that incorporates a variety of artificial intelligence technologies developed for applications such as image and speech recognition. Brant Robertson, a professor of astronomy and astrophysics who leads the Computational Astrophysics Research Group at UC Santa Cruz, said the rapidly increasing size of astronomy data sets has made it essential to automate some of the tasks traditionally done by astronomers.

Research Shows Promise of Technology Used by Turn Biotechnologies to Develop Therapies for Age-Related Diseases

Posted by in categories: biotech/medical, life extension

“We’ve wondered if it might be possible to simply rewind the aging clock without inducing pluripotency,” said Vittorio Sebastiano, assistant professor at Stanford University and senior author of the Nature Communications article. “Now we’ve found that tightly controlling the exposure to these proteins can promote rejuvenation in multiple human cell types, including stem cells. This has profound implications for regeneration and restoration of cell functionality of aged tissues.”


MOUNTAIN VIEW, Calif., March 25, 2020 /PRNewswire/ — A study published in the respected Nature Communications journal highlights the promise of technology being developed by Turn Biotechnologies to treat age-related health conditions.

The study by researchers at the Stanford University School of Medicine found that old human cells can be induced into a more youthful and vigorous state when they are exposed to a rejuvenating treatment that triggers the limited expression of a group of proteins known as Yamanaka factors, which are important to embryonic development.

Convalescent plasma is safe to treat COVID-19: nationwide study

Posted by in category: biotech/medical

The most comprehensive national study to date has found that convalescent plasma appears to be safe to use on COVID-19 patients, a promising development in the race to find a treatment for the deadly virus. But the study didn’t determine whether the treatment works.

A team of more than 5,000 doctors from over 2,000 hospitals and laboratories have been testing the experimental therapy, which involves transfusing the antibody-rich blood serum of recovered COVID-19 patients into people who are battling the illness.
