- The signals came from a red dwarf star, around 2,800 times dimmer than the Sun
- The possibility that signals came from extraterrestrial life cannot be ruled out yet, said an astrobiologist
- The signals could have also come from some kind of man-made object in space, such as a satellite
London, July 18, 2017: To the delight of those trying to find life beyond our solar system, a team of astronomers has claimed to have picked up “strange signals” emanating from a star 11 light years away.
The signals were detected by researchers from the Arecibo Observatory in Puerto Rico who are studying red dwarf stars.
On May 12 this year, the team observed mysterious radio signals emanating from a star called “Ross 128”.
“We realized that there were some very peculiar signals in the 10-minute dynamic spectrum that we obtained from ‘Ross 128’ (GJ 447), observed May 12,” wrote professor Abel Mendez, planetary astrobiologist, and director of the Planetary Habitability Laboratory at the University of Puerto Rico in a blog post.
“In case you are wondering, the recurrent aliens hypothesis is at the bottom of many other better explanations,” Mendez added.
However, the source of the mysterious signals still eludes the team.
“We do not know the origin of these signals but there are three main possible explanations: they could be emissions from ‘Ross 128’ similar to Type II solar flares, emissions from another object in the field of view of ‘Ross 128′, or just burst from a high orbit satellite since low orbit satellites are quick to move out of the field of view,” Mendez added.
The signals are probably too dim for other radio telescopes in the world and are currently under calibration.
“Therefore, we have a mystery here and the three main explanations are as good as any at this moment,” the professor said.
Dwarf stars have been shown to have planets orbiting the habitable, or ‘goldilocks,’ zone, as is the case with the recently discovered TRAPPIST-1, RT reported. (IANS)
With the festive season on in full swing, iconic brand Johnnie Walker, is all set to re-energize the country's after-hour culture. Through its one-of-a-kind campaign #RevibeTheNight, the brand brings together beloved music artists like Divine, Ritviz, Lisa Mishra, Taba Chake along with popular indie bands like When Chai Met Toast and Mad Boy Mink, among others to perform live across iconic community spaces in India.
The collaborative effort by Johnnie Walker aims to bring back the after-hour culture through live performances across popular hotspots in India. The brand's goal is drive social regeneration in India and bring back the vibe of socializing through local music artists and reignite the trade, driving social culture by executing the live events with Covid measures in place and a limited capacity audience capacity.

Prior to the world going into lockdown, the after-hour culture in India bloomed at celebrated community hubs, that eventually became a safe-haven for individuals, a place where they found their sense of self-expression and belonging, that fuelled progress. This community was driven through the culture of live music and enthralling performances that created their very own vibe, a vibe that built extraordinary, forever-lasting relationships. Through #ReVibeTheNight, one can reconnect with this community bringing music curated by artists who have a history of captivating crowds with their one-of-a-kind live experiences. Catch the gigs and live performances for artists in these venues/cities for the live performances.

In a continuing study on the effects of machine learning (ML) on public conversation, Twitter has confirmed that its algorithms amplify right-leaning political content. "In six out of seven countries - all but Germany - tweets posted by accounts from the political right receive more algorithmic amplification than the political left when studied as a group," Twitter blogged.
"Right-leaning news outlets, as defined by the independent organisations, see greater algorithmic amplification on Twitter compared to left-leaning news outlets." Since 2016, Twitter users are able to choose between viewing algorithmically ordered tweets first in their home timeline or viewing the most recent tweets in reverse chronological order.
"An algorithmic home timeline displays a stream of tweets from accounts we have chosen to follow on Twitter, as well as recommendations of other content Twitter thinks we might be interested in based on accounts we interact with frequently, tweets we engage with, and more. "As a result, what we see on our timeline is a function of how we interact with Twitter's algorithmic system, as well as how the system is designed."
The new research is based on tweets of elected officials of House of Commons members in Canada, the French National Assembly, the German Bundestag, House of Representatives in Japan, Congress of Deputies of Spain, House of Commons in the UK, and official and personal accounts of House of Representatives and Senate members in the US, as well as news outlets, from April 1 to August 15, 2020.

The study was conducted by Ferenc Huszar (Twitter, University of Cambridge), Sofia Ira Ktena (now at DeepMind Technologies), Conor O'Brien (Twitter), Luca Belli (Twitter), Andrew Schlaikjer (Twitter), and Moritz Hardt (UC Berkeley).
The questions probed were:
How much algorithmic amplification does political content from elected officials receive in Twitter's algorithmically ranked Home timeline versus in the reverse chronological timeline? Does this amplification vary across political parties or within a political party?
Are some types of political groups algorithmically amplified more than others? Are these trends consistent across countries?
Are some news outlets amplified more by algorithms than others? Does news media algorithmic amplification favour one side of the political spectrum more than the other?

Even as India celebrates reaching a milestone of 100 crore Covid vaccine doses, Snapdeal co-founder and COO Rohit Bansal on Friday lauded a man who facilitated 64 registrations for the vaccine on the CoWin portal. In a video shared on his Facebook and Twitter page, Bansal hailed Sonu Kumar as a "citizen celebrity".
Bansal said that Kumar not only helped "just co-workers and family but complete strangers too. With patience, empathy and uncanny jugaad". He added that Kumar joined him "many moons ago" and completed his open school from a parking lot.
"Education has helped this wonderful man enable others to get India back on track. Bravo! The CoWin portal on Thursday mentioned that a total of 100 crore vaccine doses has been administered so far to the eligible population under the vaccination drive in India, nine months after the nationwide inoculation programme was started to protect the people against Covid-19.
"It's a cause of significant celebration and happiness," Bansal said in the video. He said that while people just help a few around them, Kumar "bridged the digital gap" for 64 people, who were finding it difficult to register themselves online on the vaccine portal. Kumar said he doesn't feel that he has contributed much towards the 100 crore vaccine dose count. "I have been able to help only 64 people, if I was able to help more I would have been happier."
