Ukraine Dominates Social Media Info War with Russia

Ukraine has succeeded in dominating social media in the first days since the Russian invasion, in an intensifying information war with Moscow that Kyiv so far appears to be winning, analysts say.

Even as President Volodymyr Zelensky remains bunkered down in Kyiv amid heavy bombardment and the fear of assassination, his government has forced an all-out assault on social media to win supporters for their cause, AFP said.

Zelensky's daily video addresses, usually published with English subtitles, have become viral sensations, while the defense and foreign ministries tout the military resistance of Ukraine in snazzy graphics.

Meanwhile, Ukrainians have posted videos showing the success of their forces that have become viral trends, including a Ukrainian missile shooting down a Russian helicopter and a Ukrainian farmer towing away captured Russian military hardware on his tractor.

Self-shot videos of Ukrainians sobbing amid the ruins of their towns after Russia stepped up bombardments have also gripped people around the world.

More unverifiable viral claims have included the so-called "ghost of Kyiv", a flying ace said to have downed a dozen Russian warplanes, or the Kyiv woman who purportedly knocked out a Russian drone with a jar of pickled cucumbers.

"In the first phase of the conflict, in terms of international opinion, the Ukrainians are clearly ahead in information," said Baptiste Robert, founder of Predicta Lab, a French company fighting disinformation.

"The most impressive thing is that it is organic," he said. "There is a real desire of the Ukrainians to document this war. When something happens, they pull out their phones."

- 'Readjusting and trying again' -
Robert said the majority of pro-Ukraine videos doing the rounds on Twitter are genuine, but there have been claims which subsequent fact-checking proved to be exaggerated.

In the early stages of the war, Kyiv hailed as heroes 13 border guards who it said lost their lives defending a tiny Black Sea island after swearing at the Russian forces over the radio.

They had in fact all survived, as the Ukrainian authorities later acknowledged. Ukraine's embassy in Paris denies any deliberate attempt to mislead, saying "we don't do fake news".

Russia, accused of spreading disinformation in the 2016 US election to weigh the balance in favor of Donald Trump, is seen as a past master of such tactics.

But here, the balance is weighed against Moscow. In addition to being deeply unpopular in the West, the initial phase of the war has been far from successful for the Kremlin, according to independent observers.

"I can see them (the Russians) readjusting, refitting, and trying again" on the information front, said Emily Harding, deputy director and senior fellow in the international security program at the Center for Strategic and International Studies.

"But it will still take a little while to get things running."

She said she expected Russia to "push a lot of disinformation into the ecosystem about how the war is going, showing Ukrainian troops supposedly surrendering".

- 'Many Russians buy the narrative' -
However, Russia does not seem hugely concerned about public opinion outside the country, with efforts focused on keeping domestic support behind President Vladimir Putin.

To this end, Russia in the last days shut down the final bastions of free speech media in the country, blocked Facebook and restricted access to Twitter.

"It is true that they (the Ukrainians) are winning, but at the end of the day, the audience Putin cares most about is what his own people think about him," said Darren Linvill, lead researcher at the Media forensic lab of Clemson University in the United States.

"I think many, many Russians buy the narrative."

He added: "For every narrative which is pro-Ukrainian, such as stories about Russian soldiers surrendering without fighting and Ukrainian heroes being lauded for their bravery, you see the same thing in Russia, in the conversation among nationalists, for their own side."

With Ukrainian resistance forcing Moscow into a much longer war than the Kremlin wanted, a new phase in the information war is likely to open up.

If more Ukrainian cities fall to Russian forces, "there will be a new information war between those areas still resisting and the counter-information that the Russians are imposing," said Robert.

Researchers at the Paul Scherrer Institute PSI have achieved a breakthrough on the path to practical application of lithium metal all-solid-state batteries.

The team expects the next generation of batteries to store more energy, are safer to operate, and charge faster than conventional lithium-ion batteries.

The team has reported these results in the journal Advanced Science.

All-solid-state batteries are considered a promising solution for electromobility, mobile electronics, and stationary energy storage – in part because they do not require flammable liquid electrolytes and therefore are inherently safer than conventional lithium-ion batteries.

Two key problems, however, stand in the way of market readiness: On the one hand, the formation of lithium dendrites at the anode remains a critical point.

On the other hand, an electrochemical instability – at the interface between the lithium metal anode and the solid electrolyte – can impair the battery’s long-term performance and reliability.

To overcome these two obstacles, the team led by Mario El Kazzi, head of the Battery Materials and Diagnostics group at the Paul Scherrer Institute PSI, developed a new production process:

“We combined two approaches that, together, both densify the electrolyte and stabilize the interface with the lithium,” the scientist explained.

Central to the PSI study is the argyrodite type LPSCl, a sulphide-based solid electrolyte made of lithium, phosphorus, and sulphur. The mineral exhibits high lithium-ion conductivity, enabling rapid ion transport within the battery – a crucial prerequisite for high performance and efficient charging processes.

To densify argyrodite into a homogeneous electrolyte, El Kazzi and his team did incorporate the temperature factor, but in a more careful way: Instead of the classic sintering process, they chose a gentler approach in which the mineral was compressed under moderate pressure and at a moderate temperature of only about 80 degrees Celsius.

The result is a compact, dense microstructure resistant to the penetration of lithium dendrites. Already, in this form, the solid electrolyte is ideally suited for rapid lithium-ion transport.

To ensure reliable operation even at high current densities, such as those encountered during rapid charging and discharging, the all-solid-state cell required further modification.

For this purpose, a coating of lithium fluoride (LiF), only 65 nanometres thick, was evaporated under vacuum and applied uniformly to the lithium surface – serving as a ultra-thin passivation layer at the interface between the anode and the solid electrolyte.

In laboratory tests with button cells, the battery demonstrated extraordinary performance under demanding conditions.

“Its cycle stability at high voltage was remarkable,” said doctoral candidate Jinsong Zhang, lead author of the study.

After 1,500 charge and discharge cycles, the cell still retained approximately 75% of its original capacity.

This means that three-quarters of the lithium ions were still migrating from the cathode to the anode. “An outstanding result. These values are among the best reported to date.”

Zhang therefore sees a good chance that all-solid-state batteries could soon surpass conventional lithium-ion batteries with liquid electrolyte in terms of energy density and durability.

Thus El Kazzi and his team have demonstrated for the first time that the combination of solid electrolyte mild sintering and a thin passivation layer on lithium anode effectively suppresses both dendrite formation and interfacial instability.

This combined solution marks an important advance for all-solid-state battery research – not least because it offers ecological and economic advantages: Due to the low temperatures, the process saves energy and therefore costs.

“Our approach is a practical solution for the industrial production of argyrodite-based all-solid-state batteries,” said El Kazzi. “A few more adjustments – and we could get started.”


Meta Urges Australia to Change Teen Social Media Ban

Meta Urges Australia to Change Teen Social Media Ban

Tech giant Meta urged Australia on Monday to rethink its world-first social media ban for under-16s, while reporting that it has blocked more than 544,000 accounts under the new law.

Australia has required big platforms including Meta, TikTok and YouTube to stop underage users from holding accounts since the legislation came into force on December 10 last year.

Companies face fines of Aus $49.5 million (US$33 million) if they fail to take "reasonable steps" to comply.

Billionaire Mark Zuckerberg's Meta said it had removed 331,000 underage accounts from Instagram, 173,000 from Facebook, and 40,000 from Threads in the week to December 11.

The company said it was committed to complying with the law.

"That said, we call on the Australian government to engage with industry constructively to find a better way forward, such as incentivizing all of industry to raise the standard in providing safe, privacy-preserving, age appropriate experiences online, instead of blanket bans," it said in statement.

Meta renewed an earlier call for app stores to be required to verify people's ages and get parental approval before under-16s can download an app.

This was the only way to avoid a "whack-a-mole" race to stop teens migrating to new apps to avoid the ban, the company said.

The government said it was holding social media companies to account for the harm they cause young Australians.

"Platforms like Meta collect a huge amount of data on their users for commercial purposes. They can and must use that information to comply with Australian law and ensure people under 16 are not on their platforms," a government spokesperson said.

Meta said parents and experts were worried about the ban isolating young people from online communities, and driving some to less regulated apps and darker corners of the internet.

Initial impacts of the legislation "suggest it is not meeting its objectives of increasing the safety and well-being of young Australians", it said.

While raising concern over the lack of an industry standard for determining age online, Meta said its compliance with the Australian law would be a "multilayered process".

Since the ban, the California-based firm said it had helped found the OpenAge Initiative, a non-profit group that has launched age-verification tools called AgeKeys to be used with participating platforms.

China can narrow its technological gap with the US driven by growing risk-taking and innovation, though the lack of advanced chipmaking tools is hobbling the sector, the country's leading artificial intelligence researchers said on Saturday.

China's so-called "AI tiger" startups MiniMax and Zhipu AI had strong debuts on the Hong Kong Stock Exchange this week, reflecting growing confidence in the sector as Beijing fast-tracks AI and chip listings to bolster domestic alternatives to advanced US technology.

Yao Shunyu, a former senior researcher at ChatGPT maker OpenAI ‌who was named ‌technology giant Tencent's chief AI scientist in December, ‌said ⁠there was a ‌high likelihood of a Chinese firm becoming the world's leading AI company in the next three to five years but said the lack of advanced chipmaking machines was the main technical hurdle.

"Currently, we have a significant advantage in electricity and infrastructure. The main bottlenecks are production capacity, including lithography machines, and the software ecosystem," Yao said at an AI conference in Beijing.

China has completed a working prototype of an extreme-ultraviolet lithography ⁠machine potentially capable of producing cutting-edge semiconductor chips that rival the West's, Reuters reported last month. However, the ‌machine has not yet produced working chips and may ‍not do so until 2030, people with ‍knowledge of the matter told Reuters.

MIND THE INVESTMENT GAP

Yao and other ‍Chinese industry leaders at the Beijing conference on Saturday also acknowledged that the US maintains an advantage in computing power due to its hefty investments in infrastructure.

"The US computer infrastructure is likely one to two orders of magnitude larger than ours. But I see that whether it's OpenAI or other platforms, they're investing heavily in next-generation research," said Lin Junyang, technical lead for Alibaba's flagship Qwen large language model.

"We, ⁠on the other hand, are relatively strapped for cash; delivery alone likely consumes the majority of our computer infrastructure," Lin said during a panel discussion at the AGI-Next Frontier Summit held by the Beijing Key Laboratory of Foundational Models at Tsinghua University.

Lin said China's limited resources have spurred its researchers to be innovative, particularly through algorithm-hardware co-design, which enables AI firms to run large models on smaller, inexpensive hardware.

Tang Jie, founder of Zhipu AI which raised HK$4.35 billion in its IPO, also highlighted the willingness of younger Chinese AI entrepreneurs to embrace high-risk ventures - a trait traditionally associated with Silicon Valley - as a positive development.

"I think if we can improve this environment, ‌allowing more time for these risk-taking, intelligent individuals to engage in innovative endeavors ... this is something our government and the country can help improve," said Tang.
