Trees aren't an insta-fix for city air pollutionTrees were supposed to be the urban jungle's salvation. After all, trees provide sweet, beautiful shade which helps cool the metropolis, a place prone to overheating thanks to a proliferation of ... More >

Many human beings spend the majority of their time indoors, interacting with and coming into contact with other humans, and objects that other humans have touched. At the same time, we're surrounded (inside and out) by a teeming mass of millions of species of microbes that they spread to the people and things surrounding us. Recently, scientists have become interested in these tiny organisms—collectively known as the microbiome—and how they influence our health. And they've come along way. We have a much better understanding of how some of these organisms influence our weight, and our susceptibility to certain diseases.
As we learn to read, neuroplasticity conquers a network that is deeply rooted in the brain. This reorganization makes us increasingly efficient at visually navigating through letter strings, or a group of letters that appear in a word (for example, the “str” in string, straight, and strike).
Listen: we all want to believe that we make good choices. It doesn't matter if I douse my lettuce in fatty salad dressing, it's still good for me. Yes, there is an awful lot of sugary granola in my yogurt but hey, it's Greek yogurt. And maybe I do eat a lot of chocolate, but so what? It's good for my heart!
Even though VR headsets are small enough to strap onto your face, they can make objects in the virtual scene seem far off in the distance. The headsets accomplish this immersive, visual trick by having two key optical parts: screens inside that display the images, and magnifying glass-like lenses between your eyes and those screens. It's those lenses that allows a virtual dinosaur to look as if it's in the scene in front of you, and not just on small screens inches from your eyes.
When you think of gene editing technologies like CRISPR, you might imagine editing genes that relate to height, eye color, or our risk of getting certain diseases. But in truth, our DNA and RNA are full of countless proteins whose jobs have tiny yet important effects on our health. Some, for example, are heavily involved in the cell cycle, which regulates how all cells grow and divide—including cancer cells. A group of researchers out of the University of Rochester Medical Center recently used the CRISPR gene editing technique to try to eliminate one of the key proteins that allow cancer cells to proliferate out of control. While it's just a first-of-its-kind study, the researchers think that in the future, it could be incorporated into a therapy to treat the disease.
If you're looking to play it safe when it comes to illicit substances, look no further than the humble shroom. It's non-addictive, hard to overdose on, and you can grow it yourself. And, according to a massive report by the Global Drug Survey, it sends the fewest people to the emergency room of any drug on the market. Take that, meth.
Between four billion and 2.5 billion years ago, the Earth's interior was way hotter than it is today. The exterior wasn't much better. Life had barely started to evolve, so the recently-formed land was devoid of plants or animals, nascent oceans were gradually being colonized by bacteria, the atmosphere had only limited amounts of oxygen, and some lava flows were so hot that they glowed white instead of red.
In early March, D.C.'s famed cherry blossoms were ready to pop. An unusually balmy February had nudged the trees from the naked skeletal branches of dull dormancy into full flower production mode. Although most of the flowers were still young—little more than buds—some had reached a status worthy of peeping, with full “puffy white” blossoms. And then came a week of not wholly unexpected back-to-back hard freezes. It was early March, after all, and the National Oceanic Atmospheric Administration doesn't declare Washington free from frost risk until the end of April.
