Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

High Performance Samsung 950 Pro SSDs 23.09.2015

Samsung Electronics Corporation announced the first in its portfolio of M.2 consumer SSDs with an NVMe (Non-Volatile Memory Express) controller and 3D V-NAND multi-layer memory chips. We are talking about the new Samsung 950 Pro SSD series.

It includes devices equipped with a PCIe 3.0 x4 interface with a capacity of 512 and 256 GB. The first of them has a sequential read and write speed of 2500 and 1500 MB / s, respectively, with a performance of up to 300 thousand and 111 thousand IOPS on read and write operations with random access. Samsung claims a 400% improvement over traditional SATA SSD drives in terms of performance.

The presented drives, aimed at ultra-thin laptops and mobile workstations, are built on the second generation of V-NAND chips (32-layer 3-bit MLC V-NAND memory with a Samsung UBX controller). The protection system includes AES encryption technology with a 256-bit key length and the Dynamic Thermal Guard function, which ensures that the optimum temperature is maintained during operation and prevents possible data loss due to overheating.

Sales of Samsung 950 Pro SSD will start in October 2015. The 256GB version will cost $200. The double capacity model will cost $350.
