A ban on social media use for under-16s has been branded “speculative”, but the government must “continue to consider” the need to protect children, the minister said.

Science Minister Andrew Griffiths dismissed “speculative” reports that some young people’s access to social media could be restricted as part of a “potential consultation” into the issue.

Ministers are reportedly discussing the impact of sites such as TikTok and Instagram on young people’s wellbeing, with future plans potentially forcing them to get parental permission before using social networks. It is said that there is a sex.

Asked by Sky News whether such a proposal could be enforceable, Mr Griffiths said: “Well, we’re just talking about speculation.”

He said the government had already passed online safety laws that would “make activities that were illegal offline illegal online.”

But he went on to say that social media has had “real harm” as well as “good”.

“As a parent myself, I understand that parents feel a very strong need to protect their children from the evils of society that have been prevalent on social media in the past,” he said.

“We have already taken action and it is right to continue to consider it. I don’t think we can ever say the job is done.

“That is speculation about the possibility of talks taking place in the new year.”

Asked whether talks were taking place, he said: “I don’t think any of us know what’s going on and I’m not going to comment on any further talks at this point.”

The Online Safety Act was passed in October and aims to make the UK “the safest place online in the world”.

Under this law, regulations are imposed on businesses such as: meta and apple This is to ensure that inappropriate and potentially dangerous content is kept away from young people and vulnerable people.

Examples include content that promotes suicide or self-harm. The coroner handed down the verdict last year. that it contributed to teenagers Molly Russell to take one’s own life.

The law would also hold platforms accountable for illegal content such as child sexual abuse images, force adult websites to properly enforce age restrictions, and prevent underage children from creating social media accounts. The purpose is

Media regulator Ofcom will be responsible for enforcing the new rules, and companies that fail to do so will face fines of up to £18m or 10% of their global annual turnover, whichever is greater.

Companies and senior managers could also face criminal charges if it is determined that they are not doing enough to protect children, and in the most extreme cases, the platform’s operations in the UK could be suspended completely. There is also a possibility that it will be blocked.

The plumes of water vapor spewing from Enceladus’ surface appear to contain hydrogen cyanide, which, perhaps counterintuitively, suggests that there may be life in the oceans beneath the surface of this icy moon of Saturn. It shows that it is possible.

The Cassini spacecraft flew through Enceladus’ plume several times in the early 2000s, capturing samples as it hurtled past. Preliminary analyzes of these samples have revealed several elements and compounds that may be important for life, but many are not, as the molecules tend to fracture after impacting Cassini’s sampling chamber at high speeds. It has been difficult to identify specific compounds.

Jonah Peter Researchers at Harvard University performed a reanalysis of the Cassini data using new statistical methods and were able to extract more compounds present in the plume. They found evidence of several previously undetected compounds, including hydrogen cyanide, acetylene, ethane, and even trace amounts of the alcohol methanol.

All of these compounds could be part of chemical reactions important to life, but hydrogen cyanide is particularly promising.

“We still don’t have a complete picture of the molecules that are there and are necessary for the origin of life. We don’t even know how the origin of life occurred on Earth,” Peter said. say. “But we know a lot about some of the building blocks that are necessary for the beginning of life, and hydrogen cyanide is one of those very versatile building blocks.”

We know that it can be a building block for amino acids, RNA, and other large biomolecules, so its presence in the plume points to the possibility of life in Enceladus’ subsurface ocean. That’s a good sign.

A new SARS-CoV-2 variant, Pirora (BA.2.86), has been detected worldwide and is causing concern due to its high mutation rate

Researchers at the La Jolla Institute for Immunology are using immune epitope databases to predict T-cell responses to Pirora, suggesting that past exposure to existing vaccines and variants like Omicron remains important and may have a preventive effect. Although the results are promising, they are still predictive and require further experimental validation. (Credit: SciTechDaily.com)

Utilization of bioinformatics

LJI scientists are using bioinformatics to predict how T cells will adapt to fight the highly mutated Pirora mutant. In August, researchers discovered a new SARS-CoV-2 ‘Variants of concern’ in patients in Israel and Denmark. Since then, this variant has been called BA.2.86 or “Pirola” and has spread all over the world. Pirola’s mutant species is highly mutated, so caution is advised. In fact, Pirora has mutated similarly to the Omicron variant when compared to the earlier SARS-CoV-2 variants that were included in the first vaccinations. As Pyrolla spreads, researchers at La Jolla Immunology Institute (LJI) COVID-19 (new coronavirus infection) Vaccines (or previous SARS-CoV-2 infection) can still protect people from severe disease.

“The concern is that virus With so many mutations, T-cell immunity will ‘escape’,” says LJI Professor Alessandro Sette, Ph.D. in Biological Sciences. New research is currently being conducted Cell hosts and microorganisms This suggests that T cells can accurately detect mutations in pyrola and find their targets.

“Our analysis suggests there is positive news,” says LJI research assistant professor Dr. Alba Grifoni. “It appears that past exposure to Omicron, or vaccination with the new bivalent vaccine, may provide a person with T cells that can ‘catch up’ and generate a specific response to fight Pyrrha. ” LJI Professor Alessandro Sette, Doctor of Biological Sciences

Next step

Grifoni emphasizes that these findings are predictive and not observations based on actual pylora infections. Still, she thinks it’s important to see how these “in silico” (in silico) predictions are reflected in recent real-world research. “Although we still need experimental validation, we have established several collaborations around the world and are talking about this issue as we study it,” says Grifoni. Sette added that even with the Pirora variant, many people are still vulnerable to SARS-COV-2 infection. “That’s why people should still get vaccinated, especially the latest vaccines.” The researchers are currently collecting experimental data to learn more about T cell responses to the mutant strains and further strengthen their predictive tools. Griffoni is particularly interested in understanding exactly how people who have received a bivalent vaccine booster or a “breakthrough” infection will mount a T-cell response against future variants.

Potential Spread of Dengue Fever-Carrying Asian Tiger Mosquitoes to the UK Within Decades | Latest UK Updates

The Asian tiger mosquito, which carries dengue fever, could be endemic in Britain by mid-century, government health experts say.

In recent years, insects have spread to most of Europe due to the warmer climate, tending to live in urban areas and feed during the day, putting people at greater risk.

They have striped bodies and are known for their ability to spread dengue fever, Zika virus, and chikungunya fever (diseases usually associated with tropical regions).

The UK Health and Safety Agency (UKHSA) fears dengue fever could be transmitted in London by 2060, and mosquitoes themselves could be widespread across the UK by the 2040s.

UKHSA entomologist Jolyon Medlock said surveillance at borders could help slow the spread of mosquitoes, and people should cover standing water and empty containers as the insects lay their eggs to keep mosquitoes away.

Professor Dame Jenny Harries, chief executive of the UKHSA, said: “What was called a tropical disease when I was trained many years ago will actually become a national household disease.”

Officials also said other food- and water-borne infections could become more common, increasing the risk of further pandemics.

The dangers of heatwaves will worsen, flooding will become more severe, and people’s mental health may be adversely affected.

Food prices could also become more volatile, as much of the food the UK imports comes from areas prone to climate impacts such as drought.

Wildfires that produce toxic smoke are also expected to occur more frequently during hotter, drier summers.

Young children, the elderly, and people with pre-existing conditions are most vulnerable to these threats.

“In the summer of 2022, temperatures in the UK exceeded 40 degrees for the first time on record,” Dame Jenny said.

“Nearly 3,000 excess deaths were recorded during this prolonged heat wave, while many other countries have experienced extreme heat and prolonged heat waves in recent months.

“Using a high emissions scenario, health-related deaths in the UK are estimated to increase by more than 100% in the 2030s, more than 500% in the 2050s and more than 1,000% by 2070.”

Doctors fear an outbreak could occur in the UK too – and here’s why

The Earth is already 1.2 degrees warmer than pre-industrial levels, and given the amount of carbon in the atmosphere, further warming is already locked in, even if emissions start to fall overnight.

This means some adaptation will be needed, alongside emissions reductions, housing improvements, flood protection and extreme heat warnings, UKHSA said.

Mrs Jenny added: ‘Climate change is an important threat to public health around the world, not only through increased mortality from extreme temperatures and weather impacts, but also through increased spread of infectious diseases and worsened earth system vulnerabilities.”

Chinese technology giants are making a serious foray into Web3, but their potential is currently constrained

Two exhibition booths stood out at the Staking Summit in Istanbul, a conference attended by hundreds of individuals involved in staking practices in the cryptocurrency ecosystem. They belonged to Tencent and Huawei. In a backdrop dominated by people in their 20s wearing trendy corporate hoodies and handing out well-designed merchandise, China’s two tech giants feel a little out of place under the more formal corporate flag. It looked like there was.

Next to them were engineers, marketers, and business developers deeply into staking, where individuals pledge crypto assets like Ethereum to protocols in exchange for a return. The borrowed assets are then used to verify transactions within the blockchain, which implements a “proof-of-stake” method.

Over the past year, several Chinese tech giants, including Alibaba, Tencent, and Huawei, have appeared at crypto events around the world. Hoping to carve market share in the nascent Web3 space, they appear at these events with a more low-profile presence, either as official sponsors or simply as participants.

The Chinese tech giant’s participation in crypto falls somewhere at the intersection of Web 2 and Web 3, thanks to a widespread ban on crypto trading and initial coin offerings in its home country. In the most common case, these technology companies are selling their computing resources to his Web3 startups in a manner not too different from how they have sold cloud services to more established technology industry companies. Masu.

Cloud costs for companies building or leveraging decentralized networks are still understood to be negligible. While it’s not uncommon for Web2 “midsize” companies to spend $1 million or more on cloud computing, companies that qualify as Web3 midsize may only spend in the low hundreds of thousands of dollars, the speakers said. said several participants at the meeting. said the event.

However, the limited ticket size does not prevent Chinese cloud providers from venturing into cryptocurrencies. Chinese companies, the underdogs in the global cloud market, have less brand recognition, especially in the West, and are far more proactive and flexible with their customers. Therefore, companies must compete by offering cheaper or better services.

In addition to providing cloud infrastructure, Chinese companies are moving into areas outside of their core products, exposing them to competition from crypto-native companies. This includes building blockchain for enterprises. Most Chinese tech companies have stayed away from the public blockchain space, where tokens play a key role, due to the country’s cryptocurrency crackdown.

Some players also offer node-as-a-service business. A blockchain is a decentralized database that stores and encrypts transaction data and runs on distributed nodes.However, these nodes are expensive and complex to maintain, making companies like Huawei Provide node hosting services for developersis an attractive solution for companies that want to build decentralized applications but lack the technical sophistication to do so in-house.

Tencent and Alibaba were the first Chinese technology giants to enter the Web3 space and have also worked on high-profile projects to improve their reputation in the industry.

For example, Tencent has partnered with public blockchains such as Sui and Avalanche, as well as Ethereum scaling solution Scroll.

Meanwhile, Alibaba partnered with Aptos, a blockchain developed by a former Meta employee, to make its name known in the world of Web3. In a joint announcement today, Alibaba Cloud and Aptos Foundation announced that they will jointly host a hackathon using the Move programming language in the Asia Pacific region.

So far, Web3 is barely making inroads into the revenue of China’s technology giants, but these companies recognize the potential of a rapidly growing industry and are willing to take advantage of significant market swings and financial system collapse. Even in the face of it, we understand that we cannot afford to miss this opportunity. Major companies such as FTX.

New research has found that diabetes may be diagnosed with just a short audio recording from a mobile phone.

Scientists can determine whether someone has diabetes with nearly 90% accuracy using just a 6-10 second audio sample and basic health data such as age, gender, height, and weight I created an AI model.

Klick Labs recruited 267 people for the study, including some who had already been diagnosed with type 2 diabetes.

Each subject was asked to record a phrase on their phone six times a day for two weeks, and the team used AI to analyze more than 18,000 samples to determine the acoustic differences between diabetics and non-diabetics. I looked into it.

These included changes in pitch caused by type 2 diabetes that are imperceptible to the human ear.

This model had an accuracy rate of 89% for women and 86% for men.

Study author Jaycee Kaufman said the results could “change” the way we screen for diabetes.

More than 90% of adults with diabetes in the UK have type 2 diabetes, but many go undetected for years as symptoms may be systemic or absent. I am.

Testing for this disease usually requires a visit to a general practitioner and urine and blood tests.

“Current detection methods can be time-consuming, travel-intensive, and costly,” Kaufman said.

“Voice technology has the potential to completely remove these barriers.”
