In many cases, security vulnerabilities appear that affect the programs that we use on a day-to-day basis. A clear example is the browser. It may have vulnerabilities and that can allow a hacker to break in and steal passwords or personal information. That is what is happening now with Google Chrome and you should update it as soon as possible to fix a zero-day bug.

Google has released security updates to address a Zero-Day in its Chrome web browser that it said is being exploited in the wild.

The vulnerability, identified as CVE-2022–2294, relates to a buffer overflow component WebRTC that provides real-time video and audio communication capabilities in browsers, without the need to install plugins or download native applications.

The US Department of Commerce’s National Institute of Standards and Technology (NIST) has selected the first-ever group of encryption tools that could potentially withstand the attack of a quantum computer.

The four selected encryption algorithms will now reportedly become part of NIST’s post-quantum cryptographic (PQC) standard, which should be finalized in about two years.

More specifically, for general encryption (used for access to secure websites), NIST has selected the CRYSTALS-Kyber algorithm.

Researchers, led by experts at Imperial College London, have developed a new method that allows gene expression to be precisely altered by supplying and removing electrons. Scientists engineer new tools to electronically control gene expression.

New microelectronics device can program and reprogram computer hardware on demand through electrical pulses.

According to the study, smart TV sets surpassed personal computers in 2021. After smartphones, TVs are the most used device to access the Internet — from 37% of users in 2019 to 50% last year. This increase was observed in almost all analyzed demographic strata, mainly among those aged 35 to 44 (59%), users from the North Region of Brazil (45%), and women (51%). In total, 74 million individuals accessed the Internet using their television sets, an increase of 25 million users during last year.

The survey also revealed the prevalence of exclusive smartphone use to access the Internet (64% of users). According to the research, smartphones have been the main Internet access device in Brazil since 2015, and between 2019 and 2021 there was an increase of 6 percentage points in the exclusive use of phones to go online.

The exclusive use of smartphones to access the web is higher among Brazilians living in rural areas (83%), in the Northeast Region of the country (75%), black individuals (65%), those aged 60 years and over (80%), and the poorest segments of the population (89%). Among lower middle class users, access to the Internet exclusively via smartphones increased from 61% in 2019 to 67% in 2021, reaching 51 million people.

Major change for Tesla? Adding radar after years of claiming it isn’t needed for FSD?

It’s effectively a new data set that will fuel the second wave of discoveries about Mars’ surface composition.

But while it was doing that work, it was also gathering lower-resolution mapping strips, about 83,000 of them. Now that CRISM is no longer active, the team is building their map from those strips.

Processing this much data into one cohesive map is a complicated task requiring powerful computing resources. It takes time to optimize the maps and account for environmental conditions and discrepancies between the different images.

“For an individual tile, the optimization process might take just five hours in some exceptional cases, but sometimes it will take over a day,” said CRISM team member Katie Hancock, a software developer at APL who spearheaded the development of the optimization code. In a press release from JH/UAPL, Hancock said that it could take a computer cluster a month to build the map of the entire planet.

Creative thought is surely among our most precious and mysterious capabilities. But can powerful computers rival the human brain? As thinking, remembering and innovating become increasingly interwoven with technological advances, what are we capable of? What do we lose? Join Luciano Floridi, John Donoghue, Gary Small and Rosalind Picard for a thought-provoking program about thinking.

This program is part of The Big Idea Series, made possible with support from the John Templeton Foundation.

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.
