Chinese researchers have presented a new approach to ultra-high-resolution microscopy that eliminates the need for laser excitation. Instead of a laser, light generated during chemical reactions is used in the process.

By implementing a new reconstruction algorithm, it was possible to obtain an image of intracellular structures with a detail level reaching approximately 100 nanometers. This method also allows for continuous observation of living cells over a long period—up to 41 hours.
The results of this scientific work were officially published in the authoritative scientific journal Nature.
Porsche has developed a non-existent gearbox system, called E-Shift, which is an option available in the Taycan. This feature uses software to replicate the operation of an eight-speed dual-clutch PDK transmission, giving the electric sports car gear changes, jolts, and engine sounds.
It is important to note that this functionality does not increase the vehicle's speed; its main purpose is something else. One of the great advantages of electric vehicles is the instantaneous delivery of torque and continuous acceleration. However, Porsche identified that this eliminates traditional elements of the sporty driving experience, such as the feeling of increasing RPM and gear changes.
Markus Lindermeier, who is responsible for the function at Porsche, explains that E-Shift aims to add more emotion and feedback inside the car. The technology is entirely software-based, with engineers coding seven extra shifts into the electronic control units to imitate the behavior of a real PDK, including details such as downshifts during braking and distinct shifting tactics.
Lindermeier emphasizes that the goal was to maintain an authentic driving experience without incurring the disadvantages of a conventional transmission, adding that the simulated gear changes can occur faster than in combustion engine cars.
There is an interesting aspect to the engineering: the Taycan already has a two-speed mechanical gearbox on the rear axle. Porsche intentionally programmed the transition from second to third virtual gear to coincide with the actual mechanical change, making the virtual and physical overlap.
The car's performance remains unchanged. With each simulated shift, the system momentarily reduces and then restores the torque, which maintains acceleration figures and provides the driver with the expected jolt. The tachometer, located in the center of the dashboard, can reach 7,500 rpm.
The sound aspect was developed based on the Porsche Electric Sport Sound, already present in the model. Based on this, the brand created a sound that responds to the virtual rotation, load, and speed of the vehicle, in addition to a new specific sound for starting. All this audio is transmitted through the internal and external speakers of the Taycan, with a special focus on the rear part.
Activating E-Shift is done via a button on the GT sport steering wheel, allowing the driver to select between automatic and manual modes. The paddles located behind the steering wheel execute the virtual shifts. When E-Shift is deactivated, these same levers adjust energy regeneration in two stages, and pulling them simultaneously activates Push-to-Pass, releasing additional power for short periods.
If your computer relies on a slow storage system, this is the ideal time to perform an upgrade. Three options for NVMe SSDs available on sale on Amazon have been gathered. These models offer significantly higher read and write speeds than traditional HDDs, making them suitable for both building new PCs and revitalizing older machines.
The Kingston NV3, with a 1TB capacity, uses the PCIe Gen4 interface in the M.2 2280 format. It provides good bandwidth for daily use while maintaining energy efficiency. This model is a robust alternative for those who wish to expand PC storage with a reliable Kingston product, gaining agility in application loading and boot processes.
For users seeking maximum performance available on the market, the Crucial P510 employs the PCIe 5.0 interface and reaches up to 11,000 MB/s in sequential read. This speed places the storage in a distinct category from common SSDs. Furthermore, the package includes Acronis software, useful for data backup and migration, simplifying the replacement of the main drive. It is compatible with modern computers and laptops.
Another option presented is the Western Digital WD Green SN3000 500GB NVMe PCIe Gen4 – WDS500G4G0E. This model from the Western Digital line is aimed at those who need a compact and efficient SSD without requiring high capacity. With 500GB, PCIe Gen4, and a read speed of up to 5,000 MB/s in the M.2 2280 format, it is recommended for laptops and PCs that use storage as secondary or for those who prefer a simple and direct upgrade.
It is important to note that promotions like these on Amazon can change rapidly, both in terms of availability and sales conditions. Therefore, if any of these models are of interest, it is recommended to check immediately before the stock runs out.
For those who wish to upgrade the most used peripheral during games, this is a good time to check out the offers for gamer mice available on Amazon. Three wireless options with a good market reputation have been selected, allowing the reader to choose the one that best suits their playstyle.
The Cobra Pro represents the wireless version of the Redragon Cobra model, offering wireless connectivity with good battery life. It features a high-precision sensor, customizable side buttons, and customizable RGB lighting, making it suitable for both casual and demanding players. Its ergonomic design aids in long usage sessions without causing fatigue.
Another notable option is the Attack Shark X11, known for its versatility. This mouse allows connection via 2.4GHz, Bluetooth, or USB cable, making it compatible with computers, laptops, and even mobile devices. The base with RGB lighting adds an interesting aesthetic appeal for those who value their setup's appearance. Furthermore, its high-precision sensor ensures responsive tracking even during fast movements.
Weighing only 49 grams, the Astrolabe Lite is among the lightest choices presented, making it perfect for players who prioritize agile and precise movements. Its construction features a honeycomb-style perforated design, which reduces weight without compromising structural solidity. Equipped with a PAW3313 sensor up to 10,000 DPI, tri-mode connectivity (2.4GHz, Bluetooth, and USB-C), and a paracord cable, it establishes itself as a robust choice for serious competitors.
It is important to note that promotions like these tend to change quickly, and stock depletion or price changes can occur at any moment. Therefore, if any of these models catch your interest, it is recommended to visit the product page as soon as possible to secure the purchase.
