Smartphone imaging system shows promise for early oral cancer detection in dental clinics

Oral cancer remains a serious health concern, often diagnosed too late for effective treatment, even though the mouth is easily accessible for routine examination. Dentists and dental hygienists are frequently the first to spot suspicious lesions, but many lack the specialized training to distinguish between benign and potentially malignant conditions.

To address this gap, researchers led by Rebecca Richards-Kortum at Rice University have developed and tested a low-cost, smartphone-based imaging system called mDOC (mobile Detection of Oral Cancer). Their recent study, published in Biophotonics Discovery, evaluates how well this system can help dental professionals decide when to refer patients to specialists.

The mDOC device combines and autofluorescence imaging with machine learning to assess oral lesions. Autofluorescence imaging uses to detect changes in tissue fluorescence, which can signal abnormal growth. However, this method alone can be misleading, as benign conditions like inflammation also reduce fluorescence.

Curved nanosheets in anode help prevent battery capacity loss during fast charging

As electric vehicles (EVs) and smartphones increasingly demand rapid charging, concerns over shortened battery lifespan have grown. Addressing this challenge, a team of Korean researchers has developed a novel anode material that maintains high performance even with frequent fast charging.

A collaborative effort by Professor Seok Ju Kang in the School of Energy and Chemical Engineering at UNIST, Professor Sang Kyu Kwak of Korea University, and Dr. Seokhoon Ahn of the Korea Institute of Science and Technology (KIST) has resulted in a hybrid anode composed of graphite and organic nanomaterials. This innovative material effectively prevents capacity loss during repeated fast-charging cycles, promising longer-lasting batteries for various applications. The findings are published in Advanced Functional Materials.

During battery charging, lithium ions (Li-ions) move into the , storing energy as Li atoms. Under rapid charging conditions, excess Li can form so-called “dead lithium” deposits on the surface, which cannot be reused. This buildup reduces capacity and accelerates battery degradation.

Why our brain agrees on what we see: New study reveals shared neural structure behind common perceptions

How is it that we all see the world in a similar way? Imagine sitting with a friend in a café, both of you looking at a phone screen displaying a dog running along the beach. Although each of our brains is a world unto itself, made up of billions of neurons with completely different connections and unique activity patterns, you would both describe it as: “A dog on the beach.” How can two such different brains lead to the same perception of the world?

A joint research team from Reichman University and the Weizmann Institute of Science investigated how people with differently wired brains can still perceive the world in strikingly similar ways. Every image we see and every sound we hear is encoded in the brain through the activation of tiny processing units called — that are ten times smaller than a human hair. The human brain contains 85 billion interconnecting neurons that enable us to experience the world, think, and respond to it.

The question that has intrigued brain researchers for years is how this encoding is performed, and how it is possible for two people to have completely different neural codes, yet, end up with similar perceptions?

Deep blue organic light-emitting diode operates at just 1.5 V

A deep blue organic light-emitting diode (OLED) developed by researchers at Science Tokyo operates on just a single 1.5 V, overcoming the high-voltage and color-purity problems that have long limited blue OLEDs. The breakthrough was achieved by introducing a new molecular dopant that prevents charge trapping, a problem that previously hampered the performance of low-voltage OLEDs. The resulting device produces sharp blue emissions that meet BT.2020 standards, paving the way towards brighter, more energy-efficient displays.

Organic light-emitting diodes (OLEDs) are widely used in large-screen televisions and smartphone displays. Yet, among the three primary colors needed for full-color technology—red, green, and blue—the blue emitters remain the most challenging. They demand higher energy, often requiring driving voltages above 3 V, and suffer from limited long-term stability.

Now, the research team led by Associate Professor Seiichiro Izawa of the Materials and Structures Laboratory at Institute of Science Tokyo (Science Tokyo), Japan, has achieved a breakthrough in the field of OLEDs. The research team also included Professor Yutaka Majima, doctoral students Qing-jun Shui and Hiroto Iwasaki, and Master’s student Daiki Nakahigashi, all from the Frontier Materials Research Institute, Science Tokyo. They developed a deep blue OLED capable of being powered by just a single 1.5 V battery.

New Android Pixnapping attack steals MFA codes pixel-by-pixel

A new side-channel attack called Pixnapping enables a malicious Android app with no permissions to extract sensitive data by stealing pixels displayed by applications or websites, and reconstructing them to derive the content.

The content may include sensitive private data like chat messages from secure communication apps like Signal, emails on Gmail, or two-factor authentication codes from Google Authenticator.

The attack, devised and demonstrated by a team of seven American university researchers, works on fully patched modern Android devices and can steal 2FA codes in less than 30 seconds.

Google Chrome to revoke browser notifications for inactive sites

Google is updating the Chrome web browser to automatically revoke notification permissions for websites that haven’t been visited recently, to reduce alert overload.

While Google Chrome’s Safety Check tool already removes access to other permissions, such as location and camera, this new feature will extend this functionality to notifications on both desktop and Android versions of the browser.

The company said the new feature is designed to target sites that send frequent notifications that get little to no user interaction. According to Chrome product manager Archit Agarwal, although users receive a high volume of alerts, fewer than 1% of these notifications actually generate any engagement.

Insane Micro AI Just Shocked The World: CRUSHED Gemini and DeepSeek (Pure Genius)

Samsung just shocked the entire AI world — a 7-million-parameter model called Tiny Recursive Model (TRM) just out-reasoned billion-parameter giants like Gemini and DeepSeek. Built by Samsung’s Montreal research lab, this microscopic AI loops over its own thoughts, rewrites its answers, and fixes mistakes before you even see them — creating reasoning depth without size. It’s 25,000 times smaller than Gemini 2.5 Pro, yet it beat it on real reasoning benchmarks like ARC-AGI.
Meanwhile, Microsoft built an AI brain for quantum chemistry, Anthropic made an AI that audits other AIs, Liquid AI proved on-device intelligence can actually work, and Meta reinvented multimodal search — all in one insane week.

🧠 What You’ll See:
• Samsung’s 7-million-parameter TRM model that crushed Gemini and DeepSeek.
• How recursive thinking lets TRM fix its own mistakes 16 times per answer.
• Microsoft’s new neural model that changes quantum chemistry forever.
• Anthropic’s Petri framework that makes AIs audit each other.
• Liquid AI’s mobile-ready MoE model that runs locally on your phone.
• Meta’s new MetaEmbed system that rewrites multimodal search.

🚨 Why It Matters:
AI progress is no longer about size — it’s about intelligence, efficiency, and control. The smallest model just proved it can outsmart the giants.

New Android spyware ClayRat imitates WhatsApp, TikTok, YouTube

A new Android spyware called ClayRat is luring potential victims by posing as popular apps and services like WhatsApp, Google Photos, TikTok, and YouTube.

The malware is targeting Russian users through Telegram channels and malicious websites that appear legitimate. It can steal SMS meessages call logs, notifications, take pictures, and even make phone calls.

Malware researchers at mobile security company Zimperium say that they documented more than 600 samples and 50 distinct droppers over the past three months, indicating an active effort from the attacker to amplify the operation.
