Canon announced the EOS R6 Mark III, a versatile full-frame mirrorless camera featuring a 32.5-megapixel sensor, up to 7K video recording, improved autofocus, and a new dual-card slot with CFexpress Type B support, set to launch on November 25th with various kit options.
The MacBook has a serialized lid angle sensor that is integral to security and hardware calibration, making third-party replacements difficult and potentially used to prevent tampering with features like microphone disconnection when closed. This setup raises concerns about vendor lock-in and user rights, with debates about security benefits versus restrictions on repairs and modifications.
Victoria Song humorously tests Samsung's new Antioxidant Index feature on her skin and various objects, revealing that the watch's sensor can be fooled by artificial colors, leading to inaccurate antioxidant level readings.
Honda is recalling 750,000 vehicles from the 2020-2022 model years in the U.S. to address a defect that could cause air bags to deploy unintentionally during a crash. The issue stems from a crack and short circuit in the front passenger seat’s weight sensor, which fails to suppress the air bag as intended. The affected models include certain Honda Pilot, Accord, Civic, HR-V, CR-V, and Passport vehicles. This recall follows a previous recall for Honda HR-V's rear windows shattering in cold weather and a separate recall for a fuel pump issue in several Honda and Acura models.
The upcoming Galaxy S24 Ultra and Galaxy Z Fold 5 may feature a "Car Crash Detect Wakeup" sensor, potentially signaling Samsung's entry into car crash detection technology. This sensor, discovered within the One UI 6.1, is designed to report potential car crashes to apps using it and is supported by a hidden system app called "MoccaMobile." While Google and Apple have long offered similar features, Samsung's inclusion of this sensor could mark a significant step forward in smartphone safety technology.
MIT researchers have developed a battery-free sensor that can harvest energy from its surroundings, allowing for the monitoring of machines in hard-to-reach places without the need for battery replacements or wired connections, potentially revolutionizing infrastructure monitoring.
A detailed comparison of the camera on Google's Pixel 6 Pro, Pixel 7 Pro, and Pixel 8 Pro reveals that the Pixel 8 Pro, which features a newer sensor and upgrades to the Tensor chip, offers visible improvements in quality and performance. The transition between lenses is smoother, and limitations such as the inability to use the 4x telephoto lens while recording at 4K60 have been addressed. The camera on the Pixel 8 and Pixel 8 Pro is the best Google has offered so far, showcasing the company's annual generational improvements.
DJI has released the Osmo Action 4 camera, featuring a larger 1/1.3-inch sensor for improved low-light performance. However, the resolution remains limited to 4K. The camera design and battery life are unchanged from the previous model, and it supports DJI's magnetic locking system for accessories. The Action 4 offers advanced stabilization and quality-of-life features, but its stabilization falls short compared to the GoPro Hero 11. Priced at $399, the Action 4 faces tough competition from the GoPro Hero 11, which is available at the same price.
A new space weather sensor called the Multi-Needle Langmuir Probe is being sent to the International Space Station (ISS) to help scientists understand how solar outbursts affect Earth's upper atmosphere. The sensor will gather data on charged particles from the sun and their interaction with Earth's magnetic field, allowing space weather forecasters to predict disruptions to satellite communication links and navigational signals. The probe's high precision measurements will provide a more accurate understanding of how radio signals are disrupted as they travel through Earth's atmosphere, aiding in the forecasting of disruptions to satellite services. The sensor will be installed on the ISS ahead of the Crew-7 mission and will remain in orbit for approximately three years.
Supermarket trolleys fitted with a sensor in the handle can detect atrial fibrillation (AF), a heart-rhythm condition that increases the risk of stroke. During a two-month trial in Liverpool, 39 people were newly identified as having AF and were referred to a heart doctor for advice. AF is thought to affect more than a million people in the UK and 40 million globally. The study shows the potential of taking health checks to the masses without disrupting daily routines.

Biologists at the University of Geneva have identified a new type of sensor that enables the malaria parasite to know precisely where it is and what to do. This work opens up the possibility of scrambling the signals perceived by this sensor to disorient the parasite and thus prevent its replication and transmission. By identifying this sensor, scientists can now imagine how to scramble the signals perceived by the parasite at different stages of its development, thus disorienting it and blocking its multiplication and transmission.
Google's upcoming Pixel 8 and 8 Pro smartphones are expected to feature Samsung ISOCELL GN2 sensors, which are physically larger and capable of capturing 35% more light than the ISOCELL GN1 used in the Pixel 6. The Pixel 8 Pro will also reportedly feature a new time-of-flight sensor and a more modern sensor for its ultra-wide camera. Google is also planning software upgrades, including allowing users to adjust the bokeh effect in "Cinematic" video mode and a new "Adaptive torch" feature to prevent overexposure.
The upcoming Google Pixel 8 Pro is rumored to feature a dedicated IR thermometer sensor located on the rear camera housing, which can measure the temperature of external objects and a person's skin. The sensor requires access to bare skin and will not work correctly with any obstructions. While this feature is not new, it could find some niche uses as an external IR thermometer or be repurposed for other applications.
Researchers at Penn State have developed a device that mimics the human eye's ability to see color using narrowband perovskite photodetectors and a neuromorphic algorithm. The device generates electricity as it absorbs light, potentially leading to battery-free camera technology. The technology may bypass the need for filters used in current cameras, which reduce resolution and add to manufacturing complexity and cost. The findings could also trigger further developments in artificial retina biotechnology.
