Researchers from MIPT have developed a prototype detector of solar particles. The device is capable of picking up protons at kinetic energies between 10 and 100 megaelectronvolts, and electrons at 1-10 MeV. This covers most of the high-energy particle flux coming from the Sun. The new detector can improve radiation protection for astronauts and spaceships, as well as advancing our understanding of solar flares. The research findings are reported in the Journal of Instrumentation.


As energy gets converted from one form to another in the active regions of the solar atmosphere, streams of particles—or cosmic rays—are born with energies roughly between 0.01-1,000 MeV. Most

Google Shared Search Data With Feds Investigating R. Kelly Victim Intimidation Case

Topline

Google disclosed the IP addresses of anyone who searched for an arson victim’s address to the federal agents, which investigators used to pinpoint the device used by the alleged perpetrator, according to court documents unsealed earlier in the week, highlighting another instance of Google submitting to a so-called “keyword warrant.”

Key Facts

Federal investigators used the data shared by Google to link Michael Williams— an associate of musician and accused sex offender R. Kelly —  who allegedly set fire to the car belonging to a witness in the Kelly case, according to snippets of the court filings shared by Detroit News reporter Robert Snell.

“Keyword warrants” are a type of reverse search warrant in which law enforcement seeks data regarding all individuals

BISD, Facebook investigating social media threat against teacher

Beaumont ISD Police are investigating after a number of threats were sent to a teacher through anonymous Facebook accounts demanding them to “stop sending work.”

BISD spokesperson Hannah LeTulle confirmed that the district was investigating the matter, but did not provide additional details.

“The district takes any and all threats seriously and is doing so in this situation,” LeTulle said in a statement to The Enterprise, “The matter is under current investigation with the BISD Police Department.”

The messages were sent from at least three separate accounts with fake names including a character from the cartoon “Naruto,” and another with a phrase tied the hacking activist group Anonymous.


A Facebook spokesperson said the accounts have been deactivated for violating the social network’s policies prohibiting fake accounts, and that the company is investigating the matter.

None of the accounts had profile pictures or “about” information prior to their deactivation.

ICO Investigating Complaints About “Unsolicited” Texts Sent To Promote NHS COVID-19 App

The UK Information Commissioner’s Office (ICO) is investigating complaints about “unsolicited” text messages and emails sent to promote the NHS COVID-19 contact tracing app, The Register reports.

The NHS Test and Trace app, which launched on 24 September and is based on the previously-rejected Exposure Notification framework from Apple and Google, has so-far been downloaded more than 14 million times.

In a bid to encourage more Brits to install the app, NHS Digital sent texts and emails to all UK residents over the age of 16 who had previously provided their contact details to a GP. As noted by The Register, those contacted had not specifically opted in to receive marketing communications regarding the NHS COVID-19 app.

LONDON – Twitter says it’s investigating why its picture-cropping algorithm sometimes prefers White faces to Black ones.

The investigation comes after Twitter users noticed Black faces were less likely to be shown than White ones in image previews on mobile when the image contains a Black face and a White face.

The micro-blogging platform said it didn’t find any evidence of racial and gender bias when it tested the algorithm but conceded it had more analysis to do.

Parag Agrawal, Twitter’s chief technology officer, said Twitter analyzed the model when it shipped it, but said that it needs continuous improvement.

“Love this public, open, and rigorous test — and eager to learn from this,” he said on the platform.

The issue came to light after Colin Madland, a university manager
