This Chinese kissing device lets you smooch over the internet
Want to send your faraway lover a kiss? A Chinese contraption with warm, moving silicon “lips” appears to have just the answer.
The device, advertised as a way to let long-distance couples share “real” physical intimacy, is causing a buzz among Chinese social media users, who have reacted with both intrigue and shock.
Equipped with pressure sensors and actuators, the device is said to be able to mimic a real kiss by replicating the pressure, movement and temperature of a user’s lips.
First Wearable Device for Vocal Fatigue Senses When Your Voice Needs a Break
Summary: A newly developed sensor tracks a person’s vocal use and alerts them to overuse before vocal fatigue and potential injury occur.

New photodiode with extremely low excess noise for optical communication and long range LIDAR
Optical pulses, which appear as a flash of light, are used to transmit information in high speed optical fibers, and are increasingly used in Light Detection And Ranging (LIDAR) for 3-dimensional imaging. Both of these applications demand light sensors or photodiodes that are capable of detecting very low levels of light intensity down to a few photons, where a single photon is the quantized energy unit of light.
A newly published paper, “Extremely low excess noise avalanche photodiode with GaAsSb absorption region and AlGaAsSb avalanche region,” in Applied Physics Letters, details a discovery by a Sheffield research team that has the capability to transform a single electron at its input to a cascade of electrons at its output.
This multiplication process is commonly known as avalanche breakdown, while a photodiode incorporating this process is called avalanche photodiode (APD). Though the application of reverse voltage, avalanche photodiodes (often referred to as APDs) have internal gain, which means that when compared to PIN-photodiodes they typically have a higher signal-to–noise ratio.
Samsung Pro SSD reliability questioned as longtime partner shifts to Sabrent
Samsung has earned a strong reputation among PC enthusiasts when it comes to solid-state storage. Its Pro series of SSDs are often among reviewers’ top recommendations for users seeking high-speed storage for large work files, apps, and boot drives. Over the past year, though, reliability concerns around Samsung’s 980 Pro and most recent 990 Pro have marred this reputation. It has become so notable that custom PC-maker Puget Systems, a top proponent of Samsung SSDs since the SATA days, has pulled 1TB and 2TB Samsung drives from its lineup.
For Puget, problems with Samsung SSDs, which the 22-year-old boutique PC shop sells in its custom-built systems, started with the 980 Pro that came out in September 2020. On January 31, Puget wrote a blog noting it received a surprising number of reports of failing Samsung drives, specifically with the 2TB version of the 980 Pro.
The most common failure mode that we have found is that the drives are suddenly locked into read-only mode, rendering the drive unusable. If the failed drive is the primary drive, then the system becomes unbootable until the drive is replaced and the OS is reinstalled, Chris Newhart, a Tier 2 repair technician at Puget, wrote.
