Scientists expand search for signs of intelligent alien life

Published

Scientists have expanded the search for technologically advanced extraterrestrial civilizations by monitoring a star-dense region toward the core of our galaxy for a type of signal that could be produced by potential intelligent aliens that until now has been ignored, Reuters reported.

Efforts to detect alien technological signatures previously have focused on a narrowband radio signal type concentrated in a limited frequency range or on single unusual transmissions. The new initiative, scientists said on Wednesday, focuses on a different signal type that perhaps could enable advanced civilizations to communicate across the vast distances of interstellar space.

These wideband pulsating signals for which the scientists are monitoring feature repetitive patterns - a series of pulses repeating every 11 to 100 seconds and spread across a few kilohertz, similar to pulses used in radar transmission. The search involves a frequency range covering a bit less than a tenth the width of an average FM radio station.

"The signals searched in our work would belong to the category of deliberate 'we are here' type beacons from alien worlds," said Akshay Suresh, a Cornell University graduate student in astronomy and lead author of a scientific paper published in the Astronomical Journal describing the new effort.

"Aliens may possibly use such beacons for galaxy-wide communications, for which the core of the Milky Way is ideally placed. One may imagine aliens using such transmissions at the speed of light to communicate key events, such as preparations for interstellar migration before the explosive death of a massive star," Suresh added.

The effort, called the Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS), is a collaboration between Cornell, the SETI Institute research organization and Breakthrough Listen, a $100 million initiative to search for advanced extraterrestrial life, read the report.

"In the realm of searching for extraterrestrial intelligence, or SETI, we embark on a journey to detect signals from technologically advanced extraterrestrial civilizations," said astronomer and study co-author Vishal Gajjar of the SETI Institute and University of California, Berkeley.

"However, the nature of these signals remains a mystery, leaving us uncertain about their specific characteristics. Hence, it becomes crucial to explore a diverse array of signals that are unlikely to occur naturally in the cosmic environment," Gajjar added.

Using a ground-based radio telescope in West Virginia, BLIPSS has focused upon a sliver of the sky less than one-200th of the area covered by the moon, stretching toward the center of the Milky Way roughly 27,000 light years away. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).

This area contains about 8 million stars, Suresh said. If extraterrestrial life forms exist, they presumably would populate rocky planets orbiting in what is called the habitable zone, or Goldilocks zone, around a star - not too hot and not too cold.

The scientists in the various monitoring efforts passively scan for signals of alien beings and do not actively send their own signals advertising our presence on Earth, Reuters reported.

"In my opinion, transmission of 'we are here' type beacons comes with the danger of potentially inviting aliens with unknown intentions to the Earth," Suresh said.

Deliberate transmissions to potential aliens from Earth should be considered only if by global consensus humankind deems it safe and appropriate, Gajjar said.

"In my personal opinion, as a relatively young species in the grand cosmic scale, it would be prudent for us to focus on listening and investigating before embarking on deliberate transmissions," Gajjar said. "Furthermore, it is crucial to recognize that sending signals on behalf of the entire Earth raises political and ethical considerations. Presently, it would not be appropriate for a single country or entity to make decisions on behalf of the entire planet."

No aliens yet have been detected in the monitoring efforts.

"Thus far, we have not come across any definitive evidence. However, it's important to note that our exploration has been limited to a relatively small parameter space," Gajjar said.

Australia’s under-16 social media ban sparks anger and relief

Published

on

Australians reacted on Friday with a mixture of anger and relief to a social media ban on children under 16 that the government says is world-leading, but which tech giants like TikTok argue could push young people to "darker corners of the internet".

Australia approved the social media ban for children late on Thursday after an emotive debate that has gripped the nation, setting a benchmark for jurisdictions around the world with one of the toughest regulations targeting Big Tech, Reuters reported.

The law forces tech giants from Instagram and Facebook owner Meta Platforms to TikTok to stop minors from logging in or face fines of up to A$49.5 million ($32 million). A trial of enforcement methods will start in January, with the ban to take effect in a year.

"Platforms now have a social responsibility to ensure the safety of our kids is a priority for them," Australian Prime Minister Anthony Albanese said on Friday

"We're making sure that mums and dads can have that different conversation today and in future days."

Announcing the details of the ban earlier this month, Albanese cited the risks to physical and mental health of children from excessive social media use, in particular the risks to girls from harmful depictions of body image, and misogynist content aimed at boys.

In Sydney on Friday, reaction to the ban was mixed.

"I think that's a great idea, because I found that the social media for kids (is) not really appropriate, sometimes they can look at something they shouldn't," said Sydney resident Francesca Sambas.

Others were more scathing.

"I'm feeling very angry, I feel that this government has taken democracy and thrown it out the window," said 58-year-old Shon Klose.

"How could they possibly make up these rules and these laws and push it upon the people?"

Children, meanwhile, said they would try to find a way around the ban.

"I feel like I still will use it, just secretly get in," said 11-year-old Emma Wakefield.

WORLD FIRST

Countries including France and some U.S. states have passed laws to restrict access for minors without a parent's permission, but the Australian ban is absolute. A full under-14s ban in Florida is being challenged in court on free speech grounds.

Albanese's Labor party won crucial support from the opposition conservatives for the bill that was fast-tracked through the country's parliament as part of 31 bills pushed through in a chaotic final day of parliament for the year.

The government has said enough notice was given as it first flagged the ban after a parliamentary inquiry earlier this year that heard testimony from parents of children who had self-harmed due to cyber bullying.

But it was criticised by social media firms and some lawmakers who say the bill has lacked proper scrutiny.

A spokesperson for TikTok, which is hugely popular with teen users, said on Friday the process had been rushed and risked putting children into greater danger.

"We're disappointed the Australian government has ignored the advice of the many mental health, online safety, and youth advocacy experts who have strongly opposed the ban," the spokesperson said.

Albanese said on Friday passing the bill before the age verification trial has been completed was the correct approach.

"We've got your back is our message to Australian parents," Albanese said.

"We don't argue that its implementation will be perfect, just like the alcohol ban for under 18s doesn't mean that someone under 18 never has access, but we know that it's the right thing to do."

The ban could strain Australia's relationship with key ally the United States, where X owner Elon Musk, a central figure in the administration of president-elect Donald Trump, said in a post this month it seemed a "backdoor way to control access to the Internet by all Australians".

It also builds on an existing mood of antagonism between Australia and mostly US-domiciled tech giants. Australia was the first country to make social media platforms pay media outlets royalties for sharing their content and now plans to threaten them with fines for failing to stamp out scams.

South Korea authorities launch probe after three die in Hyundai car test

The Ulsan plant is Hyundai’s biggest manufacturing facility, with its own port and an annual production capacity of 1.4 million vehicles

Published

South Korean authorities launched an investigation on Tuesday after three people died during a car test at a Hyundai Motor plant in the city of Ulsan, police told Reuters.

The two Hyundai researchers and one Hyundai contractor were found unconscious in a car at around 3:00 p.m. while they were testing it in a "chamber," according to Hyundai's labour union.

South Korean media reports said the three had suffocated.

A police officer in Ulsan said the police and the labour ministry were investigating the incident, including its cause.

A fire department official told Reuters that it first received a report at 3:17 pm that the accident happened at Hyundai's No.4 factory.

"Hyundai Motor Company is deeply saddened by the incident that occurred at our plant in Ulsan, South Korea," Hyundai said in a statement, saying it would "cooperate fully with all relevant authorities to determine the cause of this incident."

The Ulsan plant is Hyundai's biggest manufacturing facility, with its own port and an annual production capacity of 1.4 million vehicles, including exports of 1.1 million units.

In November last year, Hyundai Motor broke ground on a 2 trillion won ($1.44 billion) plant in Ulsan dedicated to making electric vehicles in South Korea, as the automaker accelerated a shift away from petrol-powered cars.

Russia fines Google more than the world’s total GDP over YouTube bans

Published

on

Russia has fined Google $2.5 decillion after the US tech giant took action against pro-Kremlin TV channels on YouTube following Moscow’s invasion of Ukraine.

Russia imposed a daily fine four years ago - a fine that has since swelled to an unprecedented level - ($20,000,000,000,000,000,000,000,000,000,000,000 - a 33-digit figure).

To put this into perspective, global GDP reaches an estimated $110 thousand billion (12-digit figure), according to the IMF.

Speaking to Russia’s TASS news agency, one expert, Roman Yankovsky from the HSE Institute of Education, said Google “clearly will not pay this penalty, and the Russian Federation will not be able to recover this money from the company."

Euronews reported that a short calculation shows that he is right.

Google's holding company, Alphabet, has a market capitalisation of slightly more than $2 trillion. Even with earnings of $80.54 billion from the last quarter, the tech giant doesn’t seem to be able to afford to pay the fine.

Google first barred pro-Moscow channel Tsargrad TV, which is owned by oligarch Konstantin Malofeev, four years ago.

At the time, Google was fined a daily penalty of 100,000 roubles and warned that amount would double every 24 hours if it went unpaid.

The original fine has been compounded by further penalties after Google eventually blocked a total of 17 Russian TV channels as a result of international sanctions, The Telegraph reported.

The tech giant now owes a staggering $2.5 decillion.
