A professor from RUDN University developed new liquid crystals

A professor from RUDN University together with his Indian colleagues synthesized and studied new dibenzophenazine-based liquid crystals that could potentially be used in optoelectronics and solar panels. The results of the study were published in the Journal of Molecular Liquids.

Liquid crystals are an intermediate phase between a liquid and a solid body. They are ordered like regular chrystals but at the same time have a flow like liquids. It is this duality that allows them to be used in organic LEDs and LCDs. Unlike other liquid crystals, discotic ones (DLC) are capable of self-assembly into ordered structures. This makes them a promising material for industrial electronics, namely, for the production of displays. A professor from RUDN University together with his Indian colleagues synthesized and described new dibenzophenazine-based DLCs.

“Discotic liquid crystals are interesting because of their ability to form self-assembled ordered columnar structures. In such structures,

Tech is having a reckoning. Tech investors? Not so much.

On January 10, Charlie O’Donnell, a startup investor who runs Brooklyn Bridge Ventures, published a blog post that he hoped would inspire self-reflection among his peers in the industry. Provocatively titled Seed Investments in Insurrection, his argument was that venture capitalists needed to wrestle with their impact on democracy. 

“It’s kind of hard to make money if the long-term consequences of your investments threaten the free and open democracy that underpins our society,” he wrote, “an extreme statement—until this past week,” when “domestic terrorists, at least in part radicalized on one-time venture capital backed platforms like Facebook, YouTube, Twitch and Twitter stormed the US Capitol building.” 

The events in Washington forced technology companies to face a public reckoning over their role in promoting and amplifying extreme content. For years, critics called for social media platforms to enforce their own policies on hate speech, harassment, and incitement to violence, but … Read more

SpaceX sets new record for most satellites on a single launch with latest Falcon 9 mission

SpaceX has set a new all-time record for the most satellites launched and deployed on a single mission, with its Transporter-1 flight on Sunday. The launch was the first of SpaceX’s dedicated rideshare missions, in which it splits up the payload capacity of its rocket among multiple customers, resulting in a reduced cost for each but still providing SpaceX with a full launch and all the revenue it requires to justify lauding one of its vehicles.

The launch today included 143 satellites, 133 of which were from other companies who booked rides. SpaceX also launched 10 of its own Starlink satellites, adding to the already more than 1,000 already sent to orbit to power SpaceX’s own broadband communication network. During a launch broadcast last week, SpaceX revealed that it has begun serving beta customers in Canada and is expanding to the UK with its private pre-launch test of that … Read more

Opinion post by
Hadlee Simons

The year has just begun, but Samsung has already launched the Galaxy S21 series. This makes it the earliest ever launch for Galaxy S flagships.

Many eyes are on the base Galaxy S21 as Samsung has cut pricing to a sensible (for 2021) $800, down from the $1,000 base Galaxy S20 just a year ago. However, the biggest upgrades are reserved for the power user-friendly Galaxy S21 Ultra.

The Galaxy S21 Ultra becomes the third super-premium Samsung phone to bear the Ultra moniker, and with its latest entry, the line might finally be living up to the name.

Regulating the ribosomal RNA production line

Cryo-electron microscopy study allows researchers to visualize structural changes in an E. coli enzyme synthesizing ribosomal RNA that shift it between turbo- and slow-modes depending on the bacteria’s growth rate

The enzyme that makes RNA from a DNA template is altered to slow the production of ribosomal RNA (rRNA), the most abundant type of RNA within cells, when resources are scarce and the bacteria Escherichia coli needs to slow its growth. Researchers used cryo-electron microscopy (cryo-EM) to capture the structures of the RNA polymerase while in complex with DNA and showed how its activity is changed in response to poor-growth conditions. A paper describing the research led by Penn State scientists appears January 22, 2020 in the journal Nature Communications.

“RNA polymerase is an enzyme that produces a variety of RNAs using information encoded in DNA,” said Katsuhiko Murakami, professor of biochemistry and molecular

Multiple recent reports have sounded the death knell for Samsung’s Galaxy Note series. Some say Samsung will completely ditch the phablet line in 2021 while others insist there might be one last Note on its way out next year.

Based on these reports, we asked our readers what they think of Samsung merging the Galaxy Note series with the Galaxy S flagship line. We also asked our audience across YouTube, Twitter, and our website if they want Samsung to kill off the Galaxy Note series completely. Here are the results of both those polls.

OnePlus Nord N10 and N100 will get Android 11…and then that’s it.

Credit: Eric Zeman / Android Authority
  • OnePlus confirmed that the OnePlus Nord N10 and Nord N100 will receive just one Android upgrade.
  • Since the devices ship with Android 10, that means they’ll eventually get Android 11 and then no more upgrades after that.
  • The company did also confirm that both phones will see two years of security updates.

The OnePlus Nord series is brand new in 2020. As such, we don’t have years and years of history to look at when it comes to software upgrades, security support, etc. Up until now, that info has been all up in the air.
