One of the interesting things about the global carbon dioxide and climate systems is the concept of feedback loops. You already know that as atmospheric concentrations of carbon dioxide go up (and with them, the global average temperature) you get lots of different kinds of changes all over the place. For instance, mountain pine forests start experiencing warmer winters and smaller snowpacks. But, as those changes happen, they can actually trigger secondary effects that contribute to, and increase the rate of, climate change.
In this video, you'll learn about how warmer temperatures and lower snowpacks are contributing to the spread of massive pine beetle infestations across the western United States. This is more than just inconvenient. The pine beetles can quickly kill huge amounts of trees, raising the risk of property-destroying forest fires and razing whole ecosystems. And, as the trees die en masse, forests that were once carbon sinks (absorbing more carbon dioxide than they released) become emitters—adding more carbon dioxide to the atmosphere.
Designer Art Donovan writes, “I’m always looking for new and unique inspiration for my lighting commissions and the latest, cutting edge scientific devices offer a boatload of great design inspiration. From the cool, new ‘James Webb Space Telescope’ to the myriad of complex details in the L.H.P.C. at Cern- it’s a cornucopia of rich imagery.”
In 2009, President Obama pledged to “restore science to its rightful place.” He said, “We will not just meet, but we will exceed the level achieved at the height of the space race, through policies that invest in basic and applied research, create new incentives for private innovation, promote breakthroughs in energy and medicine, and […]
It’s hard to fund space exploration research — the commercial applications are speculative and far-off — but there’s never been a better time to study super-efficient, closed-loop botany of the sort that will someday accompany human interplanetary missions, thanks to the need to develop better grow-ops for the burgeoning legal weed market in Canada.
Some people say magic tricks are nerdy and best left to your 12-year-old asthmatic cousin. But others see value in perfecting the slight of hand and showmanship associated with a perfectly executed routine. We’re firmly in the latter camp.

Bluetooth speakers may be convenient to use, but many of them just aren’t that powerful. Sure, it may be fine if you’re seated in front of the speaker. But move across the room, and you may strain to hear what’s coming from those tiny drivers.There’s a reason why the G-BOOM Wireless Bluetooth Boombox (now $79.99 in the Boing […]
