LaserSETI Expands Its View

The ability to search for laser signals from other civilizations, rather than “traditional” radio signals, has increased significantly with new installations of LaserSETI in Hawai’i.

Each device is equipped with two identical cameras, rotated 90 degrees to one another along the viewing axis. A splitter divides the incoming light into spectra, which the camera records at a rapid rate. The wide-angle commercial lenses used in the LaserSETI devices are capable of imaging around 75 degrees, so only a few are needed to scan the entire night sky. Eliot Gillum, principal investigator for LaserSETI, said it’s “a big step forward in searching for technosignatures,” and that it’s the “first project in either optical or radio astronomy designed to cover the entire sky.”

MarsAnalogs, Lava, Mud, and Salt: Exploring Mars on Earth

In preparation for more missions to the Red Planet, including possible human explorers, scientists use locations on Earth to simulate conditions that may be found on Mars.  Other researchers, including Janice Bishop, examine and recreate the chemistry of Martian soil in the lab.

Dr. [Pascal] Lee runs the Haughton-Mars Project, an analog research facility on Devon Island, an uninhabited, barren Arctic outpost in Nunavut, Canada. “There’s an incredibly wide array of features that are similar to what we see on the moon and on Mars,” he said.

 

DunesDunes Across Many Worlds

Earth isn’t the only place in the Solar System with dunes – planets, moons, and even comets all have shown fields of wind- and/or water-sculpted landscapes. Studies of these features not only expands our understanding of these far-flung worlds, but also of our own planet, as described in this article, co-authored by Lori Fenton.

On Mars, more than 4,000 dune fields displaying a wide variety of dune forms have been mapped. Dunes have been imaged in two fields on Venus. The Rosetta spacecraft observed dunelike features on the nucleus of comet 67P/Churyumov-Gerasimenko where a tenuous and transient atmosphere—formed by vaporization of ice as the comet passes close to the Sun—may mobilize surface particles. Meanwhile, Titan, Saturn’s largest satellite, has moon-circling longitudinal dunes near its equator; Triton, Neptune’s largest moon, and Io, Jupiter’s volcanically active moon, both have surface features indicating windblown sediment transport in transient atmospheres; and Pluto features dunelike forms on the frozen-nitrogen surface of Sputnik Planitia.

 

James Webb Space TelescopeJames Webb Space Telescope Holds Possibilities for SETI

New astronomical instruments bring unexpected discoveries and answers to old questions, as well as creating new questions to be answered.  Could JWST help answer one of humanity’s oldest questions?

We can’t even begin to imagine how much more we are going to learn,” Bill Diamond, president and CEO of the SETI Institute, told the Washington Examiner in 2018. The “odds of finding extraterrestrial life only get better” with the wider range of technology at scientists’ disposal,” including the James Webb telescope, he added.

BolideBolide Detection Gets a Boost from AI

Bolides – fireballs from exploding meteors – are difficult to study.  With the aid of lightning-spotting satellites and artificial intelligence, scientists now have more data to examine.

When a blazing bright light floods the sky in the Western Hemisphere, data travel from the two lightning mappers on the GOES satellites to NOAA, where they are processed to capture lightning events. Data then branch off and travel to supercomputers at the NASA Ames Research Center to spy the bolide flashes that scientists like [Jeffrey] Smith have trained them to recognize.

CAMSStudent Involvement with SpaceML Extends the Reach of CAMS

Meteor surveillance with the CAMS system of cameras covers much of the world, but is lacking in Asia.  One student in India describes his participation the SpaceML community and working with CAMS.

In the new world order created by the pandemic, SpaceML and my experience with CAMS showcases a model of how people from different parts of the world with different skill sets, can collaborate successfully. It is evidence that geopolitical borders are no boundaries to impactful work.

keplerExoplanets – The Numbers (and Bizarre Types) Are Growing

ExoMiner, a new algorithm, has scanned the Kepler data archive to confirm over 300 new exoplanets.  Meanwhile, scientists describe some of the strangest exoplanets yet found.

Kepler-16b is an extrasolar planet that was detected in the Kepler-16 system during NASA’s Kepler mission led by Laurence Doyle of the SETI Institute back in 2011. The mission’s research team used the data from the Kepler space telescope to search for transiting planets, and noticed “the brightness of this particular system dipped even when the stars were not eclipsing one another, hinting at a third body.”

AAATeachers Explore the Stratosphere on SOFIA

The Airborne Astronomy Ambassadors program brings science educators and scientists together on NASA missions aboard SOFIA, the Stratospheric Observatory for Infrared Astronomy. The 2021 ambassadors are back on Earth, eager to share their experiences with their students.

Ultimately, the flight invigorated the teachers to continue to educate the minds of their students and hopefully spark an interest in science among them. 
“More than just content, like being able to think critically and examine graphs, being able to work together and communicate, just like the all those people on the plane,” Heflin said. “Being able to work in groups is such a big skill.” 

 

An unusually large asteroid zipped past Earth in early December.  Spoiler alert: it didn’t hit the planet.

In a hint of festive hope, astronomer Dr. Franck Marchis said the rock, known as Nereus, “is not a threat” at this time.
But he added: “Its orbit could be deviated by various things, such as an encounter with another asteroid or a planet like Venus. Any deviation could be a problem. It is as if you have an evil neighbor: you want to know where they are and what they are doing”.

 

Dixie Fire as viewed from the Hatcreek Radio ObservatoryCalifornia Wildfires Again Threatened SETI Antennas

The SETI Institute’s Allen Telescope Array (ATA) was in the path of deadly wildfires for a second time.  While personnel were evacuated as a precaution for the Dixie Fire, the array was unharmed – this time.

It would be an ironic (and very human) twist if the thing that held back the search for life in the cosmos was the terrible effects of climate change on a more telluric scale.

 

The keystone of SETI research turned 60 in 2021. Nadia Drake discusses the Equation with her father, Frank.

Scores of scientists are still guided by the equation today, and the latest discoveries about other planets both within and beyond our solar system are helping researchers to fill in the variables. It’s a remarkable legacy considering he only wrote the thing down in 1961 when he was strapped for time and needed to organise a meeting.

 

Big Picture Science

Join hosts Seth Shostak and Molly Bentley each week as they explore emerging science and technology research.

Skeptic Check: Identifying UAPs
The Pentagon’s report on UAPs (Unidentified Aerial Phenomena) said nothing about the possibility that some might be alien spacecraft. Nonetheless, the report has generated heightened interest in figuring out what these UAPs are, and that interest extends to some scientists. We talk to two researchers who want an open and strictly scientific investigation of these phenomena. What should they do and what do they expect to find? And finally, will the possibility of alien visitors ever be resolved?
 
With guests Jacob Haqq-Misra, Ravi Kopparapu

Hubble and Beyond
The universe is not just expanding; it’s accelerating. Supermassive black holes are hunkered down at the center of our galaxy and just about every other galaxy, too. We talk about these and other big discoveries of the Hubble Space Telescope, now in orbit for 30 years.

But two new next-generation telescopes will soon be joining Hubble: the Nancy Grace Roman Space Telescope and the James Webb Space Telescope. Hear what cosmic puzzles they’ll address. Plus, life in a clean room while wearing a coverall “bunny suit”; what it takes to assemble a telescope.
 
With guests Meg Urry, John Grunsfeld, Kenneth Harris

Attack of the Mutants
The omicron variant is surging. More contagious than delta, omicron demonstrates how viruses use mutations to quickly adapt.

Mutations drive evolution, although most don’t do much. But occasionally a mutation improves an organism. Omicron, the latest in a string of variants, is bad for us, but good for the virus.

How mutation of viruses ensures their own survival while threatening ours, and the prospect of a universal vaccine that would protect us against all a viruses’ variants.  

With guests Robert Garry, Kevin Saunders

Mycology Education
Beneath our feet is a living network just as complex and extensive as the root systems in a forest. Fungi, which evolved in the oceans, were among the first to colonize the barren continents more than a half-billion years ago. They paved the way for land plants, animals, and (eventually) you. 

Think beyond penicillin and pizza, and take a moment to consider these amazing organisms. Able to survive every major extinction, essential as Nature’s decomposers, and the basis of both ale and antibiotics, fungi are essential to life. And their behavior is so complex you’ll be wondering if we shouldn’t call them intelligent!

With guest Merlin Sheldrake

SETI Live

SETI Institute hosts interview cutting-edge scientists each week on social media. Recent SETI Live episodes include:

Discovering Exoplanets in Another Galaxy
For the first time, scientists may have discovered evidence of a planet in another galaxy. Using NASA’s Chandra X-ray Observatory, the possible exoplanet candidate is located in the spiral galaxy Messier 52 (M51), about 28 million light-years away from Earth. Join Franck Marchis in conversation with Rosanne Di Stefano, lead author on the study that found this exciting new planet candidate to learn how they did it and what’s next.

DART: Mission to Move a (Didy)moon
Planetary defense is one of the core concerns of scientists. Our planet is constantly being bombarded by rocks, and so far, none of those rocks have been a serious threat to humanity. However, that could change, and researchers looking to prevent a catastrophe have designed a new mission to test our ability to shift an asteroid in its orbit. The Double Asteroid Redirection Test (DART) mission is NASA’s demonstration of kinetic impactor technology, impacting an asteroid to adjust its speed and path. On November 24, 2021, the DART mission was launched and is expected to arrive at its target, asteroid Didymos’ moon Dimorphos (aka Didymoon), in 2022. Joining us to discuss DART’s objectives and science goals are three SETI Institute scientists working on the mission: Michael Busch, Matija Ćuk, and Gal Sarid. Beth Johnson will lead the discussion.

Mars Underground: Preparing Mars for Human Exploration?
The next era of Mars exploration has begun, with current and future missions highlighting the importance of subsurface science for sample return, astrobiology and human exploration. SETI Institute senior planetary astronomer Franck Marchis invited microbiologist Rachel Harris from Harvard University to discuss a session she organized at the AGU Meeting in New Orleans on the study of the interior of Mars with a focus on finding resources or sign of life on the red planet. Since this discussion was recorded from the #AGU21 meeting, we will take questions in the comments below.

SETI: Looking Back, Looking Forward
We’ve almost reached the end of 2021, and it was… a year. While everyone dealt with the pandemic and an uncertain future, we continued our outreach efforts to keep bringing science directly to the public. To close out an amazing calendar of SETI Live events, we are excited to speak with Dr. Nathalie Cabrol, Director of the Carl Sagan Center for Research, and Dr. Seth Shostak, Senior Astronomer, about the advances and progress made on our search for life beyond Earth this past year. They’ll also share their thoughts on what we can look forward to in the upcoming year, both with regards to SETI and space science. Beth Johnson will moderate.

Coming Spon: The Missions and Sights of 2022
Despite 2022 starting as an extension of 2020 and 2021, there are still new missions to be launched, more science to be done, and all the usual sights in the sky to look up at. Join Franck Marchis and Simon Steel as they give you the run down on what’s coming up in space science this year.

Social media lawsuit launched by Ontario school boards – CTV News Toronto

Published

 on


Premier Doug Ford says that lawsuits launched by four Ontario school boards against multiple social media platforms are “nonsense” and risk becoming a distraction to the work that really matters.

The school boards, including three in the Greater Toronto Area, have launched lawsuits seeking $4.5 billion in damages against Snapchat, TikTok, and Meta, the owner of both Facebook and Instagram, for creating products that they allege negligently interfere with student learning and have caused “widespread disruption to the education system.”

But at an unrelated news conference in Ottawa on Friday, Ford said that he “disagrees” with the legal action and worries it could take the focus away from “the core values of education.”

“Let’s focus on math, reading and writing. That is what we need to do, put all the resources into the kids,” he said. “What are they spending lawyers fees to go after these massive companies that have endless cash to fight this? Let’s focus on the kids, not this other nonsense that they are looking to fight in court.” 

Four separate but similar statements of claim were filed in Ontario’s Superior Court of Justice on Wednesday by the Toronto District School Board, the Peel District School Board, the Toronto Catholic District School Board, and the Ottawa Carleton District School Board.

The suits allege that the social media giants have “knowingly and/or negligently disrupted and fundamentally changed the school, learning, and teaching climate,” causing boards to suffer “substantial damages.”

According to the school boards, the damages include “a significant diversion and drain” on resources and personnel.

“The Defendants chose to maximize profits at the expense of student well-being and without due regard to the foreseeable harm and damage caused,” the statement of claims read.

None of the allegations have been proven in court. CP24 has reached out to the companies for comment.

“The influence of social media on today’s youth at school cannot be denied. It leads to pervasive problems such as distraction, social withdrawal, cyberbullying, a rapid escalation of aggression, and mental health challenges,” Colleen Russell-Rawlins, the director of education with the Toronto District School Board, said in a news release issued Thursday.

“It is imperative that we take steps to ensure the well-being of our youth. We are calling for measures to be implemented to mitigate these harms and prioritize the mental health and academic success of our future generation.”

The school boards are represented by Toronto-based law firm Neinstein LLP and the news release states that school boards “will not be responsible for any costs related to the lawsuit unless a successful outcome is reached.”

These lawsuits come as hundreds of school districts in the United States file similar suits.

“A strong education system is the foundation of our society and our community. Social media products and the changes in behaviour, judgement and attention that they cause pose a threat to that system and to the student population our schools serve,” Duncan Embury, the head of litigation at Neinstein LLP, said in the new release.

“We are proud to support our schools and students in this litigation with the goal of holding social media giants accountable and creating meaningful change.”

Ontario school boards sue social media giants for $4.5B

Published

 on

Four major Ontario school boards are taking some of the largest social media companies to court over their products, alleging the way they’re designed has negatively rewired the way children think, behave and learn and disrupted the way schools operate.

The public district school boards of Toronto, Peel and Ottawa-Carleton, along with Toronto’s Catholic counterpart, are looking for about $4.5 billion in total damages from Meta Platforms Inc., Snap Inc. and ByteDance Ltd., which operate the platforms Facebook and Instagram, Snapchat and TikTok respectively, according to separate but similar statements of claim filed Wednesday.

“These social media companies … have knowingly created a product that is addictive and marketed to kids,” said Rachel Chernos Lin, the chair of the Toronto District School Board, on CBC Radio’s Metro Morning on Thursday.

“We need them to be held accountable and we need them to create safer products.”

Social media giants ‘knowingly’ harming children, TDSB chair says in wake of lawsuit

3 hours ago

Duration 5:53

Four of Ontario’s largest school boards, including the Toronto District School Board (TDSB), have launched lawsuits against social media giants behind Meta, Snapchat and TikTok for allegedly causing harm to students. Metro Morning host David Common spoke with TDSB chair Rachel Chernos Lin about the action.

The allegations have yet to be proven in court, and there is no set date for when they will be heard. CBC Toronto has reached out to the companies named for comment.

The school boards, speaking under a new coalition called Schools for Social Media Change, allege students are experiencing an “attention, learning, and mental health crisis” because of “prolific and compulsive use of social media products,” in a news release.

They allege the platforms facilitate and promote cyberbullying, harassment, hate speech and misinformation, and have a part in escalating physical violence and conflicts in schools, according to the statements of claim.

They also argue these apps are “purposefully designed” to deliver harmful content to students dealing with topics such as suicidal ideation, drugs, self-harm, alcohol, eating disorders, hate speech and sex — particularly content encouraging “non-consensual” sexual activity.

Trying to respond to those problems has caused “massive strains” on the boards’ funds, including in additional mental health programming and staff, IT costs and administrative resources, the release says. The boards call on the social media giants to “remediate” the costs to the larger education system and redesign their products to keep students safe.

Lawsuit may be first of its kind in Canada

Hundreds of school boards in the United States, along with some states, have launched similar lawsuits against social media companies.

Last fall, over 30 states accused Meta Platforms Inc. of harming young people’s mental health and contributing to the youth mental health crisis by knowingly designing features on Instagram and Facebook that cause children to be addicted to its platforms.

In an email, a spokesperson for Snap said Snapchat was “intentionally designed to be different from traditional social media.”

“Snapchat opens directly to a camera — rather than a feed of content — and has no traditional public likes or comments. While we will always have more work to do, we feel good about the role Snapchat plays in helping close friends feel connected, happy and prepared as they face the many challenges of adolescence.”

What social media scrolling is doing to kids’ brains

5 months ago

Duration 7:52

With most children and teenagers spending hours a day on a smartphone, CBC’s Christine Birak breaks down what research shows about how using social media is changing kids’ behaviour, if it’s rewiring their brains and what can be done about it.

Neinstein LLP, a Toronto-based firm, is representing the school boards. The boards will not be responsible for any costs related to the suit unless a successful outcome is reached, the release says.

Duncan Embury, a partner and head of litigation at Neinstein, told CBC News the named companies are “mainly responsible” for the social media products that kids use, and share “common” designs or algorithms that lead to “problematic use.”

To his knowledge, this is the first case of its kind in Canada.

“Based on what we’re seeing and what we’re hearing from our educators, I think this is a problem that is pervasive across our system and I wouldn’t be surprised if there [were] more boards that took this step,” said Embury.

Ford ‘disagrees’ with move

At an unrelated news conference on Thursday, Ontario Premier Doug Ford said he “disagrees” with the schools boards’ lawsuits.

“What are they spending on lawyer fees to go after these massive companies that have endless cash to fight this? Let’s focus on the kids, not about this other nonsense that they’re looking to fight in court,” he said.

Ontario Premier Doug Ford responded to news Thursday that four major school boards in the province are suing some of the largest social media companies over alleged harm to young people, saying he disagrees with the boards’ action. “Let’s focus on the kids, not about this other nonsense,” he told reporters.

CBC News spoke to parents with children who attend schools in the Toronto District School Board. While they all agree social media apps are a problem, they differ in what approach they think should be used to regulate them.

“Just take the phones away,” said Gillian Henderson.

“I don’t think we need to sue anybody, that seems like a long, expensive process. Just take away their phones in class and give them back to them when they need them.”

The board has recently moved to develop a policy to limit cellphone use in classrooms, which includes potential phone bans and social media restrictions. It previously said staff had problems enforcing policies stating students should only use phones for educational purposes only.

(Paul Smith/CBC)

Shyon Baumann said school boards could use some help in reducing screen time.

“If the school boards can do what they can trying to police it, that would be great. But it would be also great if the app creators did what they could to make the harms decrease,” he said.

“If they’re not going to make voluntary changes, then maybe doing it through the courts is the most effective way.”

Five of the best books about social media – The Guardian

Published

 on


From Covid conspiracy theories to recent speculations about Catherine, Princess of Wales, social media is at the heart of how we share information, and misinformation, with one another in the 21st century. For those who want to have a better understanding of social media and how it affects us, here are a selection of titles that explore how we consume, share, and manipulate information on social media platforms.


So You’ve Been Publicly Shamed by Jon Ronson

Journalist and author Jon Ronson argues we live in “a great renaissance of public shaming”, and this book tracks down some of the many victims of online shaming to understand what happened to them as a result. In the process, we learn about Ronson’s own values, question our own, and figure out how we’ve reached a time where an online feed can become a social courtroom.


Doppelganger by Naomi Klein

After getting repeatedly mistaken for feminist-turned-conspiracy-theorist Naomi Wolf online, and then in real life, Naomi Klein penned Doppelganger as an earnest and introspective look at herself. The book explores how conspiracy theories and lies spread quickly through the internet, and how the social and political climate of the physical world manipulates the way we experience online platforms. While not exclusively about social media, the story behind Doppelganger is a perfect case of the ways our digital lives and identities intersect with what we experience in reality – and how dangerous the repercussions of spreading online lies can be.

Irresistible by Adam Alter

Have you ever wondered why you can’t stop scrolling on your TikTok “for you” page, or obsessing over how many likes you got on a recent Facebook post? You’re not alone, and Adam Alter’s book explores why we get sucked into the digital world. He answers what makes an online addiction, whether it be to emails, Instagram, or Netflix, different to other forms of addiction – and warns us of the dangers this could cause long-term. As well as introspection, he gives practical solutions to how digital addiction can be controlled for good.


Extremely Online by Taylor Lorenz

Journalist Taylor Lorenz calls this book “a social history of social media”; she uses real-life case studies of mothers, teenagers, politicians and influencers to assess how social media touches all demographics. Extremely Online explores topics from the digital economy and influencer culture, to what makes moments go viral on Twitter and how this is all influencing the way we socialise and understand the world. At its core, this book explores the idea of what it means to connect – and how social media as an innovation has warped communication.


TikTok Boom by Chris Stokel-Walker

TikTok is arguably one of the most significant advancements in social media in the past two decades. This book by journalist and writer Chris Stokel-Walker explores how the app is changing the way users interact with content. It moves away from the social-commentary style of the other books mentioned here, instead using business and technology analysis as a means to describe wider socio-political repercussions of the app. Stokel-Walker bridges the gap between the digital and the physical, showing the feedback loop that exists between what happens online on platforms such as TikTok and the real world.
