When it comes to sending people to Mars, one of the biggest barriers is the potential effects of the Martian environment on human health. There's still a lot we don't know about how living on Mars would affect the health of astronauts, with issues from the potentially toxic dust there to the deadly radiation which bombards the planet.
Now there's some good news for would-be explorers: A team of researchers from the University of California, Los Angeles have been investigating one part of this puzzle — the amount of radiation that Martian visitors could be exposed to — and they've found that the radiation levels shouldn't be unsafe as long as the mission lasts less than four years.
Here's a rundown of the study's findings, and what they mean for the future of space travel. |

Samsung today announced new size options for its latest QLED 4K televisions: A newer, bigger version of The Frame and a stunning, 65-inch version of The Terrace Full Sun, which is meant for the sort of backyard most of us only wish we had.
For the unfamiliar, Samsung's Terrace Full Sun TVs give you an option for outdoor entertainment that, as the name implies, is meant to be enjoyed in direct sunlight while maintaining full visibility. No word on pricing just yet, but it'll certainly cost you — the 75-inch version retails for $10,999. On the other hand, if you've got the sort of backyard in which this sort of TV fits in perfectly (as seen above), then dropping more than 10-large on an outdoor TV maybe isn't the biggest of concerns.

The graphics card inside your computer is a powerful tool for gaming and creative work, but it can also potentially serve as a Trojan horse for malware. Cybercriminals are finding ways to exploit graphics cards and their VRAM to inject malicious code into your system. The approach is claimed to have worked during a proof-of-concept hack on both discrete and integrated GPUs from AMD, Intel, and Nvidia.
Because antivirus software today cannot scan the graphics card's own video RAM, known as VRAM, hackers are now targeting GPUs to carry out their dirty work. Here's how it could potentially work, and what it could mean for the future of cybersecurity.

TIPS, TRICKS, & TECHNIQUES |
These days, music is more accessible than ever and in increasingly rich audio formats. Gone are the days of struggling to unearth a quality MP3 from whatever reputable downloader you can find online. Now, all one has to do is sign up for a top music streaming service to choose from a myriad of audio codecs — from basic MP4 files to the remarkable quality of lossless tracks and impressive Dolby Atmos sound-staging. The only thing left to worry about is the type of headphones you'll be using to experience these high-quality tracks.
While a top-rated pair of wired headphones can go a long way in enriching your listening experience, there are ways to push your chosen pair even further. That's where a headphone amp comes into play.
If you're reading this article, you probably care a lot about your wired headphones, and now you're wondering if you can improve their performance with a headphone amp. The short answer is: Yes. Depending on your headphones, there's a good chance a quality headphone amp — or a headphone amp/DAC (digital-to-analog converter) — can breathe new life into your music. But what is a headphone amp? How does it work? More to the point, how much does a decent one cost? We're here to answer all those questions and more. |
