Whiter Teeth Without the Damage? This New Powder Could Change Oral Care

0

A new vibration-activated whitening powder uses electric toothbrush motion to brighten teeth while repairing enamel and influencing oral bacteria. Tooth stains are not always a brushing problem. Some people discolor more easily because of genetics, and dark pigments from everyday items like tomatoes, coffee, and tea can gradually cling to the tooth surface. Many over-the-counter […]

The Hazards of ICE for Public Health

0

The Host

The actions of federal Immigration and Customs Enforcement agents are having ramifications far beyond immigration. Medical groups say that ICE agents in health facilities in Minneapolis and other cities are imperiling patient care, while in Washington, the backlash from a second fatal shooting by agents in Minnesota has stalled action on an eleventh-hour suite of spending bills.

Meanwhile, anti-abortion groups remain unhappy with the Trump administration over what they see as its reluctance to scale back the availability of the abortion pill mifepristone.

This week’s panelists are Julie Rovner of KFF Health News, Maya Goldman of Axios, Alice Miranda Ollstein of Politico, and Rachel Roubein of The Washington Post.

Among the takeaways from this week’s episode:

  • Concerns intensified this week over President Donald Trump’s immigration sweep after federal agents killed a second citizen in the midst of the crackdown in Minneapolis. Democrats in Congress are blocking approval of government spending as they call for renegotiating Department of Homeland Security funding, potentially forcing a partial government shutdown this weekend. In Minnesota and elsewhere, there are reports of patients postponing medical care and doctors pushing back on the presence of federal agents in hospitals.
  • After the Department of Health and Human Services cut off some federal funding to Minnesota over allegations of Medicaid fraud, other Democratic-led states in particular are fearing HHS could do the same to them. Typically the federal government conducts investigations and imposes sanctions in response to concerns of fraud; it’s unusual that HHS has opted to halt some funding instead.
  • Abortion opponents last week held their annual March for Life in Washington. The Trump administration marked the occasion by reinstating and expanding policies imposed during the president’s first term, including a ban on fetal tissue research and what’s known as the Mexico City Policy. Still, the administration has not made notable progress on a key goal of the anti-abortion movement: barring access to medication abortion.
  • Meanwhile, senators are still trying to sort out a bipartisan compromise to restart the enhanced Affordable Care Act premium subsidies that expired last year. And insurance company executives appeared before House lawmakers last week to answer questions about affordability as the Trump administration announced a plan to keep reimbursement rates nearly flat next year for private Medicare Advantage plans.

India’s Internet user base reached cusp of 1 billion led by AI adoption, short-video consumption and E-Commerce, reported the Internet and Mobile Association of India (IAMAI), a not-for-profit body representing the digital services sector, here on Thursday (January 29, 2026).

According to IAMAI’s latest edition of Internet in India report, India now has 958 million Active Internet Users (AIUs), reinforcing the country’s position as one of the world’s largest and fastest evolving digital markets. The report also reveals that rural India accounts for 57% of India’s active internet users i.e approximately 548 million active internet users.

AI seen mass adoption in the country

The ‘Internet in India Report 2025,’ jointly prepared by the IAMAI and KANTAR, and was launched at the India Digital Summit (IDS) in Bengaluru found that the country’s active internet users base grew 8% year‑on‑year growth in calendar 2025. Artificial Intelligence has reached mass adoption in the country, found the survey, which also revealed that 44% of these users were already using AI‑enabled features such as voice search, image‑based search, chatbots and AI filters. The AI usage was the highest among younger audiences, with 57% of users aged 15- 24 years and 52% of those aged 25- 44 years reporting AI usage in CY 2025.

Short-video consumption a key driver

Short‑video consumption has emerged as a key growth driver within this expanding user base. In 2025, 588 million (61%) internet users consumed short‑video content, with rural users marginally outnumbering urban users. Adoption is strongest among younger audiences, cementing their role as a key driver of digital engagement.

Again, quick commerce was leading a fundamental shift in how Indians shopped online, with social commerce close behind, as the e‑commerce ecosystem expanded beyond traditional online marketplaces, stated the report. Among urban users, 230 million people (56%) of the urban active internet base, shopped online in 2025, with quick commerce and social commerce gaining prominence alongside established marketplaces.

Multi device ownership on the rise

The study also found that multi device usership was on the rise. For instance, the country now has 193 million multi‑device internet users, representing 20% of all active internet users, up from 165 million in 2024. Urban adoption stands at 31%, while rural India is catching up at 12%. Also, shared device usage continues to be a key enabler of digital access. Some 18% of internet users go online through someone else’s mobile device, and nearly 80% of these users are based in rural areas.

The report also revealed that despite strong momentum, 38% of India’s population – about 579 million people -still remained non‑active internet users. However, this proportion has been steadily declining year after year, signalling substantial headroom for the continued expansion of India’s digital economy, it pointed out.

The Internet in India report was prepared based on the ICUBE study, which is recognised as the country’s most authoritative source on digital adoption and online behaviour. Close to 100,000 internet consumers from 400 towns and over 1,000 villages participated in the study.

UK proposes to let websites refuse Google AI search

0

Britain’s competition watchdog proposed Wednesday that websites be allowed to opt out of having content used by Google’s “AI Overviews” feature as it tackles the technology giant’s dominance in online search.

The Competition and Markets Authority (CMA) in October paved the way for tougher regulation on the matter, under new targeted measures focused on technology giants.

Last year it designated Google with “strategic market status” (SMS), subjecting it to special requirements, following a nine-month investigation.

CMA chief executive Sarah Cardell said Wednesday that the regulator’s proposal, which is out for consultation until February 25, “would give UK businesses and consumers more choice and control over how they interact with Google’s search services”.

She added in a statement that it “would also provide a fairer deal for content publishers, particularly news organisations, over how their content is used in Google’s AI Overviews”.

The CMA proposed that publishers “be able to opt out of their content being used to power AI features such as AI Overviews or to train AI models outside of Google search”.

“Google will also be required to take practical steps to ensure publisher content is properly attributed in AI results,” it added.

Website publishers, particularly media outlets, say that AI pilfers their content without compensation to feed its models.

They also argue that the AI-generated summaries discourage clicks to publishers’ original pages, reducing traffic to their sites and in turn cutting their advertising revenue.

“Google is able to extract valuable data without reward, harming publishers and giving the company an unfair advantage over competitors in the AI model market,” said Owen Meredith, chief executive of industry group, News Media Association.

Google’s search engine accounts for more than 90 percent of online enquiries in the UK, according to the regulator.

It also says that over 200,000 businesses in the UK rely on Google search advertising to reach customers.

Responding to the watchdog’s announcement, Google said it was already exploring updates to its controls “to let sites specifically opt out of search generative AI features”.

“Any new controls need to avoid breaking search in a way that leads to a fragmented or confusing experience for people,” the company’s principal for product management, Ron Eden, said in a statement.

Among its other proposals, the CMA suggests displaying a screen to facilitate changing a user’s default search engine, and rules guaranteeing a fair ranking of results, which Google should be able to demonstrate.

“These measures will give publishers – including news and other content producers – stronger bargaining power and support the long-term sustainability of trusted information online,” Will Hayter, executive director for digital markets at the CMA, said in a blog post.

“They will also help people verify sources in AI-generated results and build trust in what they see,” he added.

The UK’s stricter regulation is modelled on the European Union’s Digital Markets Act (DMA), which a handful of tech giants – including Apple, Google, and Meta – must comply with.

Google employs more than 7,000 people in the UK, according to its website.

Microsoft on Wednesday reported a 60 percent jump in net income for the last quarter of 2025, but spending on artificial intelligence surged, rattling investors.

Shares in the cloud and software giant sank about five percent in after-hours trading, with investors keeping a close eye on capital expenditures as the company spends heavily in the AI race against rivals Google, Amazon and Meta.

The company said that capital expenditures, which largely consist of the massive build-out for AI and cloud infrastructure, grew by 66 percent to $37.5 billion.

Investors are also looking at Microsoft’s ties to OpenAI, the company behind ChatGPT.

Microsoft now holds a 27 percent stake in OpenAI, which has quickly grown to become the world’s most valuable private company with a $500 billion valuation, but which some feel is overspending.

Analysts expressed worry that a sizeable chunk of Microsoft’s expected revenue over the coming quarters was from a financially overstretched OpenAI.

Microsoft said about 45 percent of its remaining cloud commitments are from OpenAI.

OpenAI is the leader in generative AI technology, but is required to raise billions every year to meet its huge expenses for computing and top engineering talent.

Beating expectations, Microsoft posted net income of $38.5 billion on revenue of $81.3 billion for the three months ending December 31.

This was up from $24.1 billion in profit on $69.6 billion in revenue a year earlier.

Analysts said that the net income figure was boosted by gains booked from Microsoft’s investment in OpenAI.

Azure and other cloud services, Microsoft’s most closely watched segment, saw revenue surge 39 percent, roughly in line with expectations.

The company said demand for cloud services continues to exceed available supply.

With this earnings result, “Microsoft didn’t declare victory on AI-but it made a credible case that the spending has a path to payback,” said Emarketer principal analyst Jeremy Goldman.

The LinkedIn professional network saw revenue grow 11 percent while revenue from Xbox gaming content and services decreased five percent. Hardware sales for Xbox were down 32 percent.

Google said on Wednesday it has taken action ‍to remove domains belonging ​to one of the largest residential ‌proxy networks in ​the world, called IPIDEA, in an effort to protect millions of consumer devices from being exploited by cybercriminals and state-sponsored hackers.

Residential proxy networks allow ​attackers to route internet traffic ⁠through hijacked consumer IP addresses, effectively masking malicious activity and bypassing security ​defences.

The operation ⁠this week, led by Google Threat Intelligence Group, or GTIG, involved taking legal action to ‌seize domains used to control ‌compromised devices and implementing automatic protections for Android ‍users through Google Play Protect, the Alphabet unit said in ‍a blog post.

“We believe our actions have caused significant degradation of IPIDEA’s proxy network and business operations, reducing the available pool of devices for the proxy operators by ⁠millions,” Google said.

IPIDEA operated at least 13 residential proxy ​brands, which were taken offline.

Google identified ⁠over 600 Android applications and 3,075 unique Windows files connected to the network’s command-and-control infrastructure.

Snap will create an independent subsidiary ‍for its augmented reality smart glasses, as it looks to ​attract external investment and challenge bigger rival Meta in ‌the fast-growing wearables market.

The launch of ​the Specs unit, announced on Wednesday, comes as the success of Ray-Ban Meta smart glasses positions eyewear as an early frontrunner in the race for gadgets powered by artificial intelligence.

But wearables is a costly bet, requiring massive capital injection for hardware, software and ​research and design capabilities, where even slight supply chain ⁠disruptions can impact production goals. Earlier this month, a supply squeeze forced Meta to pause the international expansion of its Ray-Ban Display ​glasses and focus on fulfilling ⁠U.S. orders. While Meta develops its smart glasses with EssilorLuxottica’s Ray-Ban, Big Tech rival Google has partnered with Warby Parker.

Known for its Snapchat messaging app and ‌animated filters, Snap has been doubling down on AR, ‌which can overlay digital effects onto photos, videos and users’ views of their surroundings in ‍real-time. Specs smart glasses will feature an “intelligence system” to anticipate user needs and assist them with tasks. Snap’s shares were ‍up more than 2%. The company said the new unit would open its door to minority investment and is actively recruiting for nearly 100 global positions as it moves closer to the product’s launch.

Snap has invested more than $3 billion over 11 years to develop its AR glasses, co-founder and CEO Evan Spiegel said ⁠at the Augmented World Expo last year.

“Success will depend less on breakthrough hardware innovation, but ​more on ecosystem integration and software value,” said Francisco Jeronimo, ⁠VP of devices research at market research firm International Data Corporation (IDC).

Last year, Meta dominated the smart glasses market with a 70% unit market share, followed by Xiaomi Corp at 8.5% and Huawei Technologies ⁠with 2.7%, according to IDC.

Nvidia boss hopeful of China allowing chip sales

“The actual licence for H200 is being finalised,” Huang told reporters in Taipei [File]

Nvidia chief executive Jensen Huang expressed optimism Thursday that Beijing will permit the sale to Chinese buyers of a powerful AI chip model made by the US tech giant.

Huang’s remarks came a day after the Wall Street Journal and others reported that Beijing had authorised several of Nvidia’s Chinese customers to buy the advanced chip.

The chip in question, the H200, can be used to train and run cutting-edge artificial intelligence systems.

It had been barred from sale in China by Washington over national security concerns, but last month US President Donald Trump said he had reached an agreement with China’s Xi Jinping to soften restrictions on the H200.

However, there has been uncertainty over whether the Chinese government would actually allow firms to buy them, because it has reportedly been encouraging Chinese tech companies to use domestically made chips instead.

“The actual licence for H200 is being finalised,” Huang told reporters in Taipei.

“I’m hoping… the Chinese government would allow Nvidia to sell (the) H200, so they have to decide, and I’m looking forward to a favourable decision,” he said.

“We’re looking forward to returning to China so that we can compete in the market. They have many very strong chip companies, and so we have to compete quite vigorously.”

With the United States and China locked in a fierce race for AI supremacy, Trump’s decision to allow H200 sales to China marked a significant shift in US export policy for AI chips.

The deal, under which the US government gets a 25-percent cut of sales, was confirmed by the US commerce department on January 13.

Nvidia’s most top-of-the-range chips, the Blackwell series and forthcoming Rubin processors, were not included in the agreement.

The Wall Street Journal reported Wednesday that Chinese tech companies, including Alibaba and ByteDance, have been given the green light to receive the first batch of several hundred thousand H200 chips.

More imports were expected to be approved in the coming weeks, the newspaper said, citing people familiar with the matter.

ByteDance, Alibaba and Tencent did not immediately respond to AFP’s request for comment.

The move came during Huang’s recent visit to China, which reportedly included stops in Shanghai, Beijing and Shenzhen.

It comes ahead of Trump’s planned trip to Beijing in April for talks with Xi that are aimed at resolving trade disputes.
