The focus on video games as a source of American gun violence is driving me a bit crazy, so I just wanted to toss some evidence out there. Even though most of you have likely long suspected the two things were not related, you'll be happy to know that science agrees with you. Consider this a helpful kit for forwarding to concerned relatives. Here's a 10-country comparison that found no correlation between video game consumption and gun violence. Here's a Harvard Medical School summary that explains why some people claim video games cause violence, and why the studies behind those claims aren't actually telling us that. And here's a PBS FAQ explaining a lot of the same issues. With violent video games (as with everything else) context matters.
Via US Geological Survey: This video clip shows HVO geologist Tim Orr sampling lava from an active pāhoehoe breakout on the episode 61g lava flow. The chemistry of these lava samples provides information on the magma plumbing system. Sampling has been a regular part of monitoring Kīlauea Volcano's ongoing Pu'u 'Ō'ō eruption. READ THE REST
Ultra-white is the new Vantablack. Purdue University researchers developed the whitest white paint ever. It reflects 98.1% of sunlight. (The blackest black paint, Vantablack, absorbs 99.9% of visible light.) According to lead researcher Xiulin Ruan, "f you were to use this paint to cover a roof area of about 1,000 square feet, we estimate that… READ THE REST
On Sunday, Ingenuity—the small helicopter delivered to the surface of Mars by the Perseverance rover—will, hopefully, take its first flight. The distance between Earth and Mars means that lagtime precludes real-time remote control. The helicopter flies autonomously, but the helicopter's digital twin had a lot of practice in simulations back on Earth. At IEEE Spectrum,… READ THE REST
Leadership is a magic quality that few truly possess. Oh sure, many people have to lead as part of their job description, but few actually have the inherent ability to make others better, cultivate trust, focus on problem-solving, and give team members confidence. Of course, not everybody has to be born with the ability to… READ THE REST
For any companies or individuals who fear being hacked by malevolent cybercriminals, there's some good news… and some bad news. According to an annual M-Trends report on cyber attacks, companies are spotting intrusions on their networks a lot faster than in the past. Last year, it took an average of 56 days from a first incursion… READ THE REST
If you're looking for a demarcation point between people who have a kitchen and people who actually use their kitchen, a quality blender might be a solid way of telling the difference between the two. For those whose culinary abilities don't go far beyond microwave popcorn and frozen pizza, there's likely little reason to even devote… READ THE REST
