Australia’s two most populous states are trialling facial recognition software that lets police check people are home during COVID-19 quarantine, expanding trials that have sparked controversy to the vast majority of the country’s population.

Little-known tech firm Genvis said on a website for its software that New South Wales (NSW) and Victoria, home to Sydney, Melbourne and more than half of Australia’s 25 million population, were trialling its facial recognition products. Genvis said the trials were being conducted on a voluntary basis.

The Perth, Western Australia-based startup developed the software in 2020 with WA state police to help enforce pandemic movement restrictions, and has said it hopes to sell its services abroad.

South Australia state began trialling a similar, non-Genvis technology last month, sparking warnings from privacy advocates around the world about potential surveillance overreach. The involvement of New South Wales and Victoria, which have not disclosed that they are trialling facial recognition technology, may amplify those concerns.

NSW Premier Gladys Berejiklian said in an email the state was “close to piloting some home quarantine options for returning Australians”, without directly responding to questions about Genvis facial recognition software. Police in NSW referred questions to the state premier.

Victoria Police referred questions to the Victorian Health department, which did not respond to requests for comment.

Under the system being trialled, people respond to random check-in requests by taking a ‘selfie’ at their designated home quarantine address. If the software, which also collects location data, does not verify the image against a “facial signature”, police may follow up with a visit to the location to confirm the person’s whereabouts.

Though the technology has been used in WA since last November, it has more recently been pitched as a tool to enable the country to reopen its borders, ending a system in place since the start of the pandemic that requires international arrivals to spend two weeks in hotel quarantine under police guard.

Aside from the pandemic, police forces have expressed interest in using facial recognition software, prompting a backlash from rights groups about the potential to target minority groups.

While the recognition technology has been used in countries like China, no other democracy has been reported as considering its use in connection with coronavirus containment procedures.

‘Keep communities safe’

Genvis Chief Executive Kirstin Butcher declined to comment on the trials, beyond the disclosures on the product website.

“You can’t have home quarantine without compliance checks, if you’re looking to keep communities safe,” she said in a phone interview.

“You can’t perform physical compliance checks at the scale needed to support (social and economic) re-opening plans so technology has to be used.”

But rights advocates warned the technology may be inaccurate, and may open the window for law enforcement agencies to use people’s data for other purposes without specific laws stopping them.

“I’m troubled not just by the use here but by the fact this is an example of the creeping use of this sort of technology in our lives,” said Toby Walsh, a professor of Artificial Intelligence at University of NSW.

Walsh questioned the reliability of facial recognition technology in general, which he said could be hacked to give false location reports.

“Even if it works here … then it validates the idea that facial recognition is a good thing,” he said. “Where does it end?”

The government of Western Australia has said it banned police from using data collected by COVID-related software for non-COVID matters. The WA police say they have put 97,000 people through home quarantine, using facial recognition, without incident.

“The law should prevent a system for monitoring quarantine being used for other purposes,” said Edward Santow, a former Australian Human Rights Commissioner who now leads an artificial intelligence ethics project at University of Technology, Sydney.

“Facial recognition technology might seem like a convenient way to monitor people in quarantine but … if something goes wrong with this technology, the risk of harm is high.”

SpaceX's Starship to Deploy Mock Starlink Satellites in Flight 7 Test

Elon Musk’s SpaceX said on Friday its upcoming Starship test flight would include the rocket’s first attempt to deploy payloads in space by releasing 10 model Starlink satellites, a key demonstration for Starship’s potential in the satellite launch market.

“While in space, Starship will deploy 10 Starlink simulators, similar in size and weight to next-generation Starlink satellites as the first exercise of a satellite deploy mission,” SpaceX said in a blog post on its website.

The Starship flight from SpaceX’s sprawling Boca Chica, Texas facilities, tentatively planned for later this month, will mark the seventh demonstration in a test-to-failure style of rocket development where the company tests new upgrades with each flight.

In October, Starship’s “Super Heavy” first stage booster returned to its launch pad’s giant mechanical arms for the first time, a milestone for its fully reusable design.

The rocket’s sixth test flight in November, attended by U.S. President-elect Donald Trump, achieved similar mission objectives – besides the landing of Super Heavy, which was forced to target a water landing on the Gulf of Mexico because of a launchpad problem.

Starship is the centerpiece of SpaceX’s future satellite launch business – an area it currently dominates with its partially reusable Falcon 9 – as well as Musk’s dreams to colonize Mars.

The rocket’s power, stronger than the Saturn V rocket that sent Apollo astronauts to the moon in the last century, is key for launching huge batches of satellites into low-Earth orbit and is expected to rapidly expand the company’s Starlink satellite internet network.

SpaceX is under contract with NASA to land U.S. astronauts on the moon later this decade using Starship.

Musk, SpaceX’s founder and CEO, has become a close ally of Trump who has made getting to Mars a more prominent goal for the incoming administration.

Are There Binary Black Holes at the Heart of Galaxies

Supermassive black holes are believed to exist at the centre of most galaxies, including our Milky Way. However, in certain cases, two such black holes are thought to orbit one another, forming binary systems. These gravitationally bound pairs could provide significant insights into the dynamics of galaxy formation and the behaviour of space-time. Detecting them, however, presents challenges due to their nature, as they cannot be observed directly using traditional telescopes.

Gravitational Waves and Galactic Collisions

According to research, as reported by The Conversation, binary black holes can form when galaxies merge. During such collisions, the black holes from the merging galaxies are brought closer by gravitational forces. Eventually, they may create a binary system before combining into one larger black hole over millions of years.

These systems emit gravitational waves, ripples in space-time predicted by Albert Einstein’s theory of general relativity. Observatories like the Laser Interferometer Gravitational-Wave Observatory (LIGO) detect these waves, though pinpointing individual binaries remains elusive.

Evidence from Active Galactic Nuclei

Researchers have identified a potential binary black hole system in an active galaxy, PG 1553+153, as reported by The Conversation. Observations have revealed periodic light variations approximately every 2.2 years, which could indicate the presence of two orbiting black holes.

Active galactic nuclei, which emit immense energy due to gas accretion, often display such cyclical patterns. These patterns, however, might also result from other phenomena like jet wobbles, requiring further investigation.

Historical Data and Findings

As reported by The Conversation, they used archival data spanning over a century, a secondary 20-year light variation pattern was identified in PG 1553+153. This additional evidence supports the binary black hole hypothesis, suggesting the system includes two black holes with masses in a 2.5:1 ratio. Final confirmation, however, may depend on advancements in pulsar timing arrays to detect specific gravitational waves.

The study highlights how historical data and modern simulations contribute to understanding complex cosmic events. The findings advance knowledge of galactic evolution and black hole behaviour, with future technological improvements expected to refine these discoveries.

Battle Site Between Alexander the Great and Ancient Persians Discovered

The site of Alexander the Great’s decisive Battle of the Granicus against the Persian Empire appears to have been uncovered in northwest Turkey. Archaeologists have pinpointed the location roughly 10 kilometres north of Biga, where the famed confrontation occurred in 334 B.C. This victory allowed Alexander to establish a critical foothold in Persian territory, marking a pivotal moment in his campaign and reshaping the trajectory of ancient history. Evidence unearthed at the site includes remains of the ancient city of Hermaion, believed to have been Alexander’s final encampment before the battle.

Findings Based on Historical and Scientific Evidence

According to a report by Live Science, the team led by Reyhan Körpe, an archaeology professor at Çanakkale Onsekiz Mart University, carried out extensive research to validate the battlefield’s location. Historical records describing the terrain were compared with modern geomorphological studies. These studies revealed that the Granicus River’s path has remained largely unchanged since ancient times, while nearby marshy areas were ruled out as potential sites for the battle.

Further supporting the discovery were findings from Hermaion, including graves unearthed by local farmers in 2024. Among these, human bones discovered on a hillside believed to have housed Persian Greek mercenaries were examined. While the absence of grave markers suggests an informal burial, tests are ongoing to determine the age and cause of death of the remains.

Next Steps in Excavation

Plans for geophysical surveys and detailed digs have been announced to explore the site’s deeper layers and provide more insights into this historic confrontation. The team’s work offers a glimpse into Alexander’s military strategy and the broader impact of his campaigns on ancient civilisations.
