A while back we talked about a few of graphene’s many uses such as curing cancer, treating cavities, and prolonging battery life. The wonder nanomaterial already sounds pretty incredible, but it now looks like researchers have only scratched the surface when it comes to harnessing its power. As unbelievable as it seems, graphene can apparently even help spiders to spin incredibly strong webs. As you probably already know, a spider’s web is already very strong as it is, especially the one created by the giant riverine orb spider. As far as biologists know, members of this species are capable of spinning the strongest silk in nature, but by adding a bit of graphene to the equation a group of scientists were able to make silk that’s 3.5 stronger than that of the giant riverine orb spider.

At first glance this might not seem like a big deal, however, the interesting part comes from the fact that graphene was not added to the webs in order to make them stronger, but rather, it was sprayed on the spiders themselves. A team of researchers from the University of Trento, Italy created a spray made out of graphene nanotunes and water and used it on some 15 Pholcidae spiders. The process by which the spiders were able to assimilate the material and use it to create the incredibly strong silk is not yet fully understood by the researchers. However, the team was able to learn that only some of the specimens were capable of the amazing feat, with others spinning an inferior type of silk while four of them ended up dying because of the graphene.

It is assumed that the spiders were actually trying to get rid of the foreign substance through their silk as opposed to being aware that graphene could make their webs stronger. According to the study, “spiders could spin graphene and nanotubes in the silk also as an efficient way of eliminating them from their organism.” This new type of silk is now considered to be among the strongest materials out there and could have a wide range of potential applications, ranging from reinforced armor to bionics.

Redwire Space has “bioprinted” a human knee meniscus on the International Space Station, which could treat Earthlings with meniscus issues.

The meniscus cartilage was manufactured on Redwire’s ISS BioFabrication Facility (BFF). The BFF printed the meniscus using living human cells and transmitted it to Redwire’s Advanced Space Experiment Processor for a 14-day enculturation process for BFF-Meniscus-2.

SpaceX’s Crew-6 mission returned the tissue to Earth after culturing. UAE astronaut Sultan Al-Neyadi and NASA astronauts Frank Rubio, Warren Hoburg, and Stephen Bowen investigated.

Redwire collaborated with the Uniformed Services University of the Health Sciences Center for Biotechnology, which studies warfighter remedies, for the trial. Meniscus injuries are the most prevalent orthopedic injuries in U.S. service members.

In recent months, Redwire Space has advanced biotechnology. The subsidiary of Redwire Corporation launched a 30,000-square-foot biotech and microgravity research park in Indiana this summer.

Redwire EVP John Vellinger called the printing “groundbreaking milestone.”

He stated, “Demonstrating the ability to print complex tissue such as this meniscus is a major leap forward toward the development of a repeatable microgravity manufacturing process for reliable bioprinting at scale.”

The company has long-term bioprinting and space microgravity research goals. Redwire will fly microgravity pharmaceutical drug development and cardiac tissue bioprinting payloads on a November SpaceX Commercial Resupply trip to the ISS.

Sierra Space agreed to integrate Redwire’s biotech and in-space manufacturing technology into its Large Integrated Flexible Environment (LIFE) space station module. Orbital Reef, a private space station designed by Blue Origin, Boeing, and others, will include LIFE.

Although the CES doesn’t start until tomorrow, we’re back in Vegas for the event, and several exhibitors have already shown their new items at numerous press conferences and media events. In addition to more news from TV manufacturers, gaming laptop manufacturers, smart home firms, and other companies, we are starting to see some of the early automotive news that typically headlines CES today. Here is a summary of the top news from Day 1 of CES 2023 in case you haven’t caught up yet.

Since last night
But first, even though we covered the most of yesterday’s launches in a different video, more things were announced last night after we had finished filming that. For instance, Withings demonstrated the $500 pee-scanning U-Scan toilet computer.

It’s a 90mm block that you install inside your toilet bowl as a deodorizer and employs a microfluidic device that functions like a litmus test to identify the components in your pee. Although Withings is developing a consumer-focused version that will evaluate your nutrition and hydration levels and forecast your ovulation and period cycles, you will need to decide the precise tests you wish to run in your module. Prior to launching in the US, it is still awaiting regulatory approval from the European Union.

We also witnessed the Fufuly pulsing cushion by Yukai Engineering, which was less… gross news. Although a vibrating cushion may sound like something out of an anime, the concept is that cuddling something that might simulate real-life pulsation may have calming effects. Another thing that could calm anxiety? watching a video of adorable birds! Additionally, Bird Buddy unveiled a brand-new intelligent feeder with a built-in camera so you can watch your feathered friends while they build nests. The most recent version, which is intended for hummingbirds, uses AI to recognize the different breeds that are in the area and, in conjunction with a motion sensor, determines when they are ready for a feast.

Speaking of nibbles, there was a ton of food-related technology news last night, like as the $1,000 stand mixer from GE Profile that has a digital scale and voice controls. We also observed OneThird’s freshness scanners, which determine the freshness of produce using near-infrared lasers and secret algorithms. Even the shelf life of an avocado can be determined instantly, preventing food waste!

We also witnessed the Wisear neural earbuds that let you control playback by clenching your jaw, the blood pressure monitor that hooks onto your finger from Valencell, and Loreal’s robotic lipstick applicator for people with limited hand or arm mobility. Smart speakers, smart pressure cookers, smart VR gloves, smart lights, and more were available.

Let’s move on to the recent news. Prior to the onslaught that is set to happen tomorrow, there was only a little trickle of auto news. Volkswagen debuted the ID.7 EV sedan, tempting us with only the name and a rough body form. BMW, meanwhile, revealed the I Vision Dee, or “Digital Emotional Experience,” to provide additional information about its futuristic I Vision concept vehicle development. It’s a simplified design with a heads-up display that spans the entire front windshield. Many of the Dee’s characteristics are anticipated to be incorporated into production vehicles starting in 2025, notably BMW’s new NEUE KLASSE (new class) EV platform. BMW’s Mixed Reality slider will also be available on the Dee to regulate how much digital stuff is shown on the display.

TVs
The premium 2023 TVs from Samsung were also not unveiled until the evening, with this year’s models emphasizing on MiniLED and 8K technologies. Additionally, it added more sizes to its selection and unveiled new soundbars with Dolby Atmos capability at all price points. While this was going on, competitor LG unveiled a 97-inch M3 TV that can wirelessly receive 4K 120Hz content, allowing you to deal with fewer connections in your living room and… more soundbars. Leave it to LG and Samsung to essentially duplicate each other’s actions.

Hisense, a competitor with comparatively smaller TVs, today announced its 85-inch UX Mini LED TV, which has more than 5,000 local dimming zones and a maximum brightness of 2,500 nits. Startup Displace, meanwhile, demonstrated a brand-new 55-inch wireless OLED TV that can be attached to any surface via vacuum suction, doing away entirely with the requirement for a wall mount or stand. You can even live without a power cord thanks to its four inbuilt batteries. Essentially, this is a fully functional, portable TV.

Laptops

We also noticed more HP, MSI, and ASUS laptops. A laptop with glasses-free 3D, a sizable Zenbook Pro 16X with lots of space for thermal dissipation, and a Zenbook 14X with a ceramic build are all products of ASUS. Both of the latter Zenbooks include OLED displays. In the meantime, HP unveiled a new line of Dragonfly Pro laptops that are designed to simplify the purchasing process for customers by removing the majority of configuration options. The Windows version exclusively uses an AMD CPU and has a column of hotkeys on the right of the keyboard that provide shortcuts to camera settings, a control center, and 24/7 tech support, whilst the Dragonfly Pro Chromebook has an RGB keyboard and Android-like Material You theming capabilities. The last of these buttons can be programmed to open a particular program, file, or website.

The first of some audio news is now being presented to us, starting with JBL. The business presented its array of five soundbar models for 2023, all of which will support Dolby Atmos. New true wireless earbuds with a “smart” casing including a 1.45-inch touchscreen and controls for volume, playback, ANC, and EQ presets were also introduced. Nearly simultaneously, HP unveiled the Poly Voyager earphones, which are comparable to the JBL in terms of controls and have a touchscreen on the carrying case. However, the Voyager also features a Broadcast mode that enables you to connect the case to an older device with a headphone port (like while you’re on an airline) via the provided 3.5mm to USB-C connection, so you can view movies during a flight without having to bring along a second set of headphones.

Not only today but also the remainder of the week will see a ton more CES news. I was unable to tell you about Citizen’s latest wristwatch or Samsung’s new, more affordable Galaxy A14 smartphone. Keep checking back for updates on all CES 2023 news.

Concerns Regarding Free PSVR2 Upgrades Book II of Raised by Moss, Moss

When Sony’s next VR headset launches in February 2023, the PSVR classics Moss and Moss: Book II will have native PSVR2 editions, but the catch for current owners is that they’ll have to pay full price to play them. There isn’t even a paid upgrade route, Polyarc has confirmed to Push Square, and neither title will be eligible for free PSVR to PSVR2 upgrades.

Due to a 10% PS Store discount, Moss will instead be available for $17.99, while its sequel will cost $26.99. This price is expected to expire soon. As an alternative, you can get them both together for $34.99.

Lincoln Davis, director of communications for Polyarc, provided the following explanation as to why the company chose this course of action: “For PSVR2 owners who previously bought the PSVR versions of the games, cross-buying is not configured for those titles. The appropriate implementation of new platforms for works like Moss and Moss: Book II requires a lot of time and money. And in this instance, the majority of that work was devoted to fine-tuning both games to offer gamers improved experiences that take advantage of the new hardware technology.”

According to the creator, the PSVR2 versions are configured to benefit from all the features the Sony headset boasts of, including haptic feedback, adaptive triggers, eye tracking, and a larger field of view. Additionally, it will utilize a 4K resolution at 90 frames per second with enhanced lighting and texture.

Although they claim to utilise the same features and provide a free PSVR to PSVR2 upgrade, games like After the Fall and No Man’s Sky will. It puts PSVR2 buyers in the frustrating position of having to pay for some titles all over again while receiving free access to others that promise the same exact improvements. If you want to purchase the updated version of a game you already own, Polyarc isn’t even going the Sony route and offering a $10 upgrade path. Instead, individuals who purchase the smartphone on launch day must pay full price.
