Current virtual reality headsets are pretty good at the "virtual" bit but tend to fall down on the "reality" side of things. It's all too obvious that you're looking at a screen, albeit a screen held very close to your face, and a lot of screens just aren't meant to be looked at that close. The "screen door" effect that breaks the display up into a grid of individual pixels is distracting, and resolutions are low enough that curved lines are noticeably jagged, and fine detail gets lost. Second-generation headsets like the Vive Pro certainly do better than their first-generation counterparts, but they haven't eliminated these shortcomings. Even with eyes as appalling as mine, the human optical systems are clearly higher quality than the VR headsets can satisfy.
But the Varjo VR-1, available to buy today, is the first headset I've used that convincingly provides an image that looks real. The VR-1 puts a 1920×1080 micro-OLED display with some 3,000 pixels per inch (or 60 pixels per degree) slap-bang in the middle of your field of view. It looks like nothing you've ever seen from a headset before: no pixel grid, no jagged lines (nor the anti-aliasing usually used to hide the jaggies), no screen-door effect. The images it displays look every bit as detailed as real life. Varjo calls it the Bionic Display and claims its resolution is about that of the eye, giving it a level of fidelity like nothing else on the market.
Surrounding this screen is a conventional 1440×1600 AMOLED display providing an 87 degree field of view. This showed an image that's much like any other headset. I found the experience of using the VR-1 a little like that of using Microsoft's HoloLens. In the HoloLens, the display has a relatively narrow field of view, so you have to look straight forward to see the images. When looking around, you have to turn your whole head and keep your eyes looking more or less straight ahead if you want to look at something. Otherwise, as soon as you look off to the side, the 3D images disappear.
If developing heart disease scares the poo out of you, this new monitor may be just the thing.
Engineers at Rochester Institute of Technology have designed a high-tech toilet seat that effortlessly flushes out data on the state of your cardiovascular system. The tricked-out porcelain throne measures your blood pressure, blood oxygen level, and the volume of blood your heart pumps per beat (stroke volume)—taking readings every time you sit down to catch up on some reading of your own. The engineers, led by David Borkholder, recently published a prototype of the seat in the open-access journal JMIR mHealth and uHealth.
According to the inventors, the seat’s daily data dump could make patients and their doctors privy to early warning signs of heart failure, potentially helping to prevent further deterioration and avoid costly hospital stays. Moreover, the seat could ease in-home monitoring for heart patients, who often strain to consistently track their tickers with other, non-toilet-based monitors.

If you didn’t notice any Blu-ray player announcements from Samsung at CES this year, there’s a reason for that: the company has told both Forbes and CNET that it is getting out of the Blu-ray player business in the United States.
The large chaebol conglomerate will introduce no new Blu-ray players anywhere, it seems, and will stop making existing players for the US market. This comes as a confirmation of what many observers expected, given that the company last released a new player in 2017. Samsung was reportedly working on a high-end Blu-ray player for release in 2019, according to Forbes, but those plans have been scrapped.
Samsung didn't tell either publication why it decided to exit the business, and there is probably no big, single reason for this shift. But there are a lot of small ones.
Ren Zhengfei says the firm will survive despite security concerns and his daughter's legal troubles.
Since the beginning of the year, the US government and private security companies have been warning of a sophisticated wave of attacks that’s hijacking domains belonging to multiple governments and private companies at an unprecedented scale. On Monday, a detailed report provided new details that helped explain how and why the widespread DNS hijackings allowed the attackers to siphon huge numbers of email and other login credentials.
The article, published by KrebsOnSecurity reporter Brian Krebs, said that, over the past few months, the attackers behind the so-called DNSpionage campaign have compromised key components of DNS infrastructure for more than 50 Middle Eastern companies and government agencies. Monday’s article goes on to report that the attackers, who are believed to be based in Iran, also took control of domains belonging to two highly influential Western services—the Netnod Internet Exchange in Sweden and the Packet Clearing House in Northern California. With control of the domains, the hackers were able to generate valid TLS certificates that allowed them to launch man-in-the-middle attacks that intercepted sensitive credentials and other data.
Short for domain name system, DNS acts as one of the Internet’s most fundamental services by translating human-readable domain names into the IP addresses one computer needs to locate other computers over the global network. DNS hijacking works by falsifying the DNS records to cause a domain to point to an IP address controlled by a hacker rather than the domain’s rightful owner. DNSpionage has taken DNS hijacking to new heights, in large part by compromising key services that companies and governments rely on to provide domain lookups for their sites and email servers.
