  • Chinese Android Phone Brands Said to Be Testing Under-Display Cameras and 3D Face Unlock

    Chinese Android Phone Brands Said to Be Testing Under-Display Cameras and 3D Face Unlock

    Apple uses a 3D facial recognition system known as Face ID for secure authentication in its iPhone models. This Face ID embedded within a display cutout has long set the benchmark for smartphone facial recognition. So far, most Android manufacturers have yet to match it with a comparable and widely adopted alternative. Now, a new leak coming out of China suggests that some Android smartphone companies are exploring similar 3D solutions for their upcoming devices. Honor’s latest Magic 7 Pro already offer a face unlock feature that employs a system similar to Apple’s Face ID.

    Under-Display 3D Face Recognition Technology in Testing Phase

    Tipster Digital Chat Station on Weibo claimed that several Chinese smartphone makers are testing under-display 3D facial recognition technology in domestic labs. While the product name or brand names haven’t been disclosed, the post hints at increasing interest in integrating advanced biometric solutions directly beneath the display. This could allow smartphone makers to offer secure face unlock without visible camera cutouts with advanced biometrics. 

    The comment section of the post shows that some users are skeptical about the adoption of under-screen cameras and 3D face recognition. They opine that they could take up more space and increase the cost of the handsets.

    Apple’s iPhone models have maintained the Face ID feature for nearly a decade. The 3D face recognition is considered secure and reliable for unlocking the phone and for authenticating payments. Currently, similar systems are available on select Android devices from brands like Honor and ZTE.

    Honor’s recent flagship Magic 7 Pro offers 3D face unlock, similar to Apple’s Face ID. It boasts a central pill-shaped cutout at the top of the screen housing a 50-megapixel selfie camera and a 3D depth camera. The 3D face unlock feature is claimed to work even in the dark.

    Honor’s Magic 6 Pro also features a 3D facial recognition system. Meanwhile, ZTE’s Nubia Z70S Ultra features an under-display (UD) selfie camera, but it doesn’t offer 3D face scanning.

    In meeting with Naqvi, Iranian president warns of Israel’s attempts to divide Muslim world

    Interior Minister Mohsin Naqvi (left) meets Iranian President Masoud Pezeshkian on July 15, 2025. — Radio Pakistan
    • “Will never forget Pakistan’s support during Israel war”, says Iran.
    • Tehran highlights opportunities to boost bilateral cooperation.
    • Mohsin Naqvi congratulates President Pezeshkian on “great victory”.

    During a meeting with Interior Minister Mohsin Naqvi, Iranian President Masoud Pezeshkian said that Iran attached great importance to its relations with Islamabad and thanked the minister for support during the recent 12-day war against Israel.

    Warning that Israel was trying to create a rift among Muslim countries, President Pezeshkian called for “inevitable” unity and harmony among Islamic countries.

    Underscoring the importance of diplomatic exchanges and constructive dialogue to enhance cooperation between the two countries, he expressed satisfaction over the current bilateral relations between the neighbouring nations..

    The Iranian president further accentuated that Pakistan and Iran had immense opportunities to enhance cooperation, saying that his country would never forget the support extended by Pakistan during their war with Israel.

    Meanwhile, Naqvi congratulated President Pezeshkian on achieving a “great victory” and recalled Pakistan’s support to Iran, saying that Islamabad strongly condemned the attack against Tehran at every forum.

    He noted that Pakistan’s parliament was the first to pass a resolution condemning the war imposed on Iran and supported Iran’s legitimate right to self-defence.

    The two leaders’ remarks come weeks after a 12-day armed conflict between Israel and Iran broke out on June 13 following Israeli airstrikes on Iranian military, nuclear, and civilian targets, resulting in at least 606 deaths and 5,332 injuries, according to Iran’s Health Ministry.

    In response, Tehran carried out missile and drone attacks on Israel, killing at least 29 people and injuring over 3,400, based on data from the Hebrew University of Jerusalem.

    The conflict also saw the US bombing Iran’s multiple nuclear facilities and claimed that the strikes destroyed Iran’s nuclear programme.

    The fighting eventually ended with a US-brokered ceasefire that began on June 24.

    Meanwhile, on the nuclear issue, Tehran has said that its cooperation with the International Atomic Energy Agency (IAEA) “will take on a new form” and has expressed desire for a diplomatic solution to resolve concerns over its nuclear programme.

    Iran’s cooperation with the IAEA “has not stopped, but will take on a new form”, after the Islamic republic formally ended cooperation with the UN watchdog in early July.

    Iran has blamed the IAEA in part for the June attacks on its nuclear facilities, which Israel says it launched to prevent Iran from developing a nuclear weapon — an ambition Tehran has repeatedly denied.

    Two sniffer dogs retire after years of loyal service

    Listen to article

    Two sniffer dogs of the Khyber-Pakhtunkhwa (K-P) Police, credited with thwarting dozens of terrorist plots, have been officially retired after serving for a decade.

    The dogs were part of the special bomb disposal and security unit operating across Peshawar and the tribal districts.

    These British-bred sniffer dogs played a critical role in bomb disposal operations and provided security clearances for high-profile officials, including the Prime Minister, Chief Minister, and Governor.

    They were also instrumental in clearing routes and detecting dozens of suspicious items during various security operations.

    According to Adil Abdal, director of K-P’s K9 unit, the dogs worked closely with the police, Counter-Terrorism Department (CTD), and other law enforcement agencies during numerous search and strike missions.

    Their efforts neutralised two major improvised explosive devices (IEDs) and helped keep key routes safe from potential threats.

    Due to age, the dogs were retired but remain valued assets of the K-P Police. Following retirement, they have attracted significant interest from individuals willing to adopt them.

    A senior Peshawar police official highlighted the dogs’ key role during sensitive periods such as Muharram and VIP visits, noting their ability to detect threats well in advance, thereby enhancing security measures.

  • Optogenetic screening can help curb age-related diseases

    Optogenetic screening can help curb age-related diseases

    Researchers at Integrated Biosciences have developed a novel platform that enables millisecond- and micron-level control over previously intractable biological systems, unlocking new therapeutic opportunities in age-related diseases.

    The platform combines optogenetics, chemistry, and AI to discover small-molecule therapeutics for age-related diseases.

    A new peer-reviewed publication demonstrates the platform’s capabilities by applying it to the integrated stress response (ISR), a key aging and disease-associated signalling pathway implicated in neurodegeneration, cancer, and viral infections.

    Benefits of ISR for reducing pathology of age-related diseases

    The scientists used optogenetic control to selectively activate the ISR, leading to the discovery of several ISR-potentiating compounds that sensitise stressed cells to apoptosis without inducing cytotoxicity across diverse cell types and stressors — an elusive therapeutic profile not achievable with traditional ISR drugs in development.

    The lead compounds identified in the study showed broad-spectrum antiviral activity in vitro, and one compound significantly reduced disease pathology and viral titres in a mouse model of ocular herpesvirus age-related infection.

    A powerful new approach to drug discovery

    The new platform allows for precise and dynamic control of biological targets and processes, unlocking a powerful new approach to drug discovery.

    By integrating programmable, light-responsive domains with automated high-throughput screens, the platform interrogates biological systems with millisecond temporal precision and micron-scale spatial resolution.

    This uniquely modular system allows researchers to resolve compound effects in real time, across diverse targets, cell types, and age-related diseases, providing a level of precision and control not achievable with conventional screening technologies.

    “Synthetic biology tools like optogenetics allow us to precisely tune complex cellular processes, something traditional drug screening can’t do,” said Maxwell Wilson, PhD, Co-Founder and Chief Scientific Officer of Integrated Biosciences.

    “Our platform lets us activate specific targets and pathways with light, generating clean, interpretable readouts and the discovery of high-precision compounds, often with unprecedented mechanisms of action, that were previously inaccessible.”

    A major advantage over traditional screening tools

    Unlike traditional perturbation agents and pharmacological tools, the platform enables selective, pathway-specific activation without the off-target or systemic confounding effects, generating clean, high-fidelity, on-pathway datasets.

    This is especially critical in phenotypic screening and AI-driven discovery, where data quality remains a major bottleneck to extracting meaningful insights.

    It also offers a generalisable strategy for discovering small molecules that modulate complex, traditionally hard-to-drug targets and pathways, including age-related diseases.

    As the system is modular and tuneable, it can be rapidly adapted to explore a wide range of biological processes with on-pathway, on-phenotype precision – a major advantage over traditional screening tools.

    Wilson concluded: “This is only the first demonstration of what our optogenetic platform can do.

    “Synthetic biology gives us the control we need to build more accurate, disease-relevant discovery systems. Our goal is to bring this level of precision to other pathways where conventional tools have failed.”

    Trump ‘disappointed, but not done’ with Putin as he backs Nato on Ukraine – Europe live | US news

    ‘Disappointed in him, but not done with him’, Trump says of Putin as he offers his backing to Nato

    On Putin, Trump said he thought he had a deal with him on Ukraine “four times.”

    “I’m disappointed in him, but I’m not done with him, but I’m disappointed in him.

    We had a deal done four times and then you go home and you see just attacked a nursing home in Kyiv. And so what the hell was that all about?”

    Asked if he trusted him, he said:

    I trust almost nobody, to be honest with you.

    Trump also said he strongly supported Nato, saying that “Nato is now becoming the opposite of” being obsolete, as he once said.

    He added it was “very unfair because the United States paid for almost 100% of it, but now they are paying their own bills.”

    Asked if he believes in Nato’s fundamental Article 5 on collective defence, he said:

    Yeah, I think collective defence is fine.

    Trump also spoke on how his relationship with European leaders changed over the years, saying “it’s maybe not all luck; it’s like when you do it twice, it’s a big difference.”

    “Over the years, they’ve gotten to know me.

    This is not an easy crowd to break into. You understand, these are smart people heading up very, very successful generally, countries, you know, they’re all Germany and France, Spain and, you know, big countries.

    And you know, I’ve gotten to know them, and I think they’ve come to respect my, respect me and my decision making.”

    Irish tourist jailed by Ice for months after overstaying US visit by three days

    Sam Levin

    In other news, we reported earlier today on a disturbing story of an Irish tourist jailed by the US Immigration and Customs Enforcement for months after overstaying US visit by three days.

    From there, what should have been a minor incident became a nightmarish ordeal: he was detained by Ice in three different facilities, ultimately spending roughly 100 days behind bars with little understanding of why he was being held – or when he’d get out.

    “Nobody is safe from the system if they get pulled into it,” said Thomas, in a recent interview from his home in Ireland, a few months after his release. Thomas asked to be identified by a nickname out of fear of facing further consequences with US immigration authorities.

    Despite immediately agreeing to deportation when he was first arrested, Thomas remained in Ice detention after Donald Trump took office and dramatically ramped up immigration arrests.

    Amid increased overcrowding in detention, Thomas was forced to spend part of his time in custody in a federal prison for criminal defendants, even though he was being held on an immigration violation.

    Thomas was sent back to Ireland in March and was told he was banned from entering the US for 10 years.

    Thomas’s ordeal follows a rise in reports of tourists and visitors with valid visas being detained by Ice, including from Australia, Germany, Canada and the UK. In April, an Irish woman who is a US green card holder was also detained by Ice for 17 days due to a nearly two-decade-old criminal record.

    The arrests appear to be part of a broader crackdown by the Trump administration, which has pushed to deport students with alleged ties to pro-Palestinian protests; sent detainees to Guantánamo Bay and an El Salvador prison without presenting evidence of criminality; deported people to South Sudan, a war-torn country where the deportees had no ties; and escalated large-scale, militarized raids across the US.

  • Flight may have started with a tiny dinosaur wrist bone

    Flight may have started with a tiny dinosaur wrist bone

    New scans of two small predatory dinosaurs reveal a pea-sized wrist bone once thought unique to birds. The research suggests that the engines of flight were revving inside dinosaur arms long before any creature flapped skyward.

    The study was led by James Napoli of Stony Brook University with colleagues at the American Museum of Natural History and the Mongolian Academy of Sciences.


    The research overturns earlier claims that theropods lacked a bird-like pisiform and raises the possibility that the path to powered flight was, as the authors put it, “all in the wrist.”

    Dinosaur wrist bone on the move

    Modern birds fold their wings automatically when the elbow bends. The hinge works because a tiny carpal called the pisiform migrated from the edge of the wrist to replace another bone, the ulnare.

    Its new spot lets a V-shaped notch clamp the hand bones and stop them from popping loose during vigorous flapping.

    For years, paleontologists assumed non-avian dinosaurs never made that switch. Napoli’s team tested the dogma by CT-scanning an exquisitely preserved troodontid, a quick, velociraptor-like hunter. They also scanned an oviraptorid, a beaked omnivore with a long neck.

    Digital slices peeled away surrounding rock, isolating each pebble-sized carpal in three dimensions. The images showed a bead-like bone tucked where the pisiform sits in modern birds.

    “We believe this is the first time a migrated pisiform in a non-bird meat-eating dinosaur has been identified,” Napoli said.

    The discovery pushes the joint’s redesign back to Pennaraptora, a diverse branch of feathered theropods that includes velociraptors, troodontids, and oviraptorosaurs.

    “While we currently do not know precisely how many times dinosaurs learned to fly, it is intriguing that experimentation with flight in these creatures appears only after the pisiform migrated into the wrist joint,” Napoli explained.

    “Therefore, it is possible this established the automated mechanisms found in current living birds, though we would need to test this hypothesis with more research and analysis of dinosaur wrist bones.”

    The scientists argue that the pisiform’s relocation was gradual. Early pennaraptorans still carried a small ulnare. Later species lost that bone entirely as the pisiform enlarged and took over its role.

    Gradual wrist bone replacement

    The replacement mirrors other avian traits – hollow bones, enlarged brains, filamentous feathers – that spread outward through theropod evolution before coalescing into true birds.

    According to the authors of the study, the findings make clear that the topological and functional replacement of the ulnare by the pisiform occurred much deeper in theropod history than has been previously understood and was a stepwise process.

    “Over the past few decades, our knowledge of theropod dinosaur anatomy and evolution has increased exponentially, much of it revealing that classically ‘avian’ traits such as thin-walled bones, an enlarged brain, and feathers, all characterize more inclusive groups of theropod dinosaurs,” noted the researchers.

    “Our results suggest that the construction of the avian wrist is no exception and follows topological patterns laid down by the origin of Pennaraptora.”

    Scans reveals hidden features

    Identifying the bone took both luck and technology. The fossils – discovered in Mongolia’s Cretaceous rocks – had escaped crushing, so their wrist bones lay undisturbed.

    Micro-CT resolution below 50 microns allowed the researchers to trace delicate sutures, distinguishing the pisiform’s spoon-like head and its telltale notch.

    Without such scans, the structure would look like one of several nubs commonly lumped together as generic carpals.

    Wrist bone shaped evolution

    Flight appears to have evolved at least twice within Pennaraptora and perhaps as many as five times. If the pisiform swap predates those experiments, it may have primed the limb for aerial feats in separate lineages.

    That echoes convergent “upgrades” seen in pterosaurs, bats, and birds, where wrist and shoulder tweaks unleash new kinematic possibilities.

    The finding also casts fresh light on grounded relatives like Velociraptor. Though too heavy to fly, such animals wielded feathered arms for display, brooding, or balance.

    A bird-style pisiform would have let them tuck and unfurl their limbs with mechanical efficiency. This hints that the crouched, wing-guarding pose seen in some fossil nests used the same automatic folding action modern roosters employ.

    Future fossil finds

    Future work will scan additional fossils to see exactly when the pisiform first slid into place. The researchers want to investigate whether the move coincided with feather lengthening or muscle shifts.

    They also hope to model forces across the joint to test how much stability the new bone adds during flapping or mantling motions.

    For now, the lesson is clear: tiny parts can steer colossal evolutionary leaps. A marble-sized bone drifting a few millimeters may have set the stage for the skies to fill with beating wings. It began inside dinosaur wrists millions of years before the first true birds appeared.
