Despite how important it is to our health, cholesterol is one of the more complicated things about the diet and the human body. First, there’s HDL and LDL. Common knowledge states that LDL is the bad one, and HDL is the good one. So far, so good. But, it turns out that there are versions of LDL that are good, and versions of HDL that are bad. Well, that’s not that helpful.
Know this: Cholesterol does something good for you, so you want some of it. Eggs, long blamed as a prime cholesterol carrier, apparently DON’T have those naughty, naughty cholesterol particles that are bad for you. Time to make a scramble.
Where Do We Sign Up?
Everything that goes up on a rocket has to be perfect, and it has to be light, and it has to be well-tested. Spacecraft, with no way to get fresh air, end up smelling about as bad as you can imagine. That's why these brave sniffers clock in to sniff toilets.
They're trying to find the best way to reduce odors and keep those spacecraft comfortable. So far, the best odor-absorber has been activated charcoal, a form of powdered charcoal that whisks away odors without requiring any other chemicals or electricity. Ah, the future of spaceflight.
Hard to Argue
Just like lots of other pieces of technology, Auto-Tune (or in its more general term, pitch correction) is a tool for musicians and singers. If you don't have a lot of time to burn in the studio and you flubbed a note, give it a little shift. Some might notice, but you might have to do it. The number of people who have come to rely on pitch correction to make their careers has led to some stunningly bad music.
T-Pain might get us to laugh, but putting on a new track and hearing a voice that sounds almost robotic is never fun, especially for those who have come to appreciate the beauty of a natural voice.
The Better Kind of Crash
Thankfully, when they talk about crashes here, they mean a computer crash – you know the kind. You have to hold the power button down for five seconds and hope you don't lose too much work. Computers are still getting better and better, but they still have plenty of faults. Just try to update AMD graphics drivers, you'll see what I mean. If these big jetliners aren't rebooted, the computer system begins to show misleading data to the pilots, and if there's one person we never want to be shown misleading data, it's pilots.
These huge planes often stay on for days, weeks, or months at a time, even during refueling, maintenance checks, and overnight. We're not sure how long it takes to reboot these machines, but it's probably more than a few minutes.
Where Did It Come From?
Herbal medicine's favorite tree, the Gingko, is known as a living fossil. Newly-found specimens are remarkably similar to plants that have been found to be more than a hundred million years old. There are some samples that are several thousand years old, and trees that are hundreds of years old. Fossils reveal that the trees have remained largely unchanged for the past fifty-one million years.
While there are subtle differences – the shape of the leaves, the way seeds are formed – for the amount of time they might as well be exactly the same. If you want to know what dinosaurs snacked on, just look up these trees.
