Developed by researchers at Queen’s University, the BitDrones System is envisioned as a collaborative, three dimensional interface. A user can toggle through options on a menu of drones, which rotate in a circle like an old iPod click wheel as created by Tony Stark. Once the options are selected, cubes fly into place as free-floating shapes for the architect to tweak. At one moment in a demonstrational video, the architect selects a color from a palette presented on a screen by a third variety of tiny quadcopter....

Then, that smoke did something even more unexpected, according to new research published today in Nature: it fell on the Southern Ocean to the east of Australia, sparking a months-long algal bloom. The bloom spanned thousands of miles, with uncertain effects on both marine life and global emissions—and illustrated how we’ve only just begun to understand the global ripples of climate change. “When you see the images of the wildfires, the environmental impact of these fires is pretty obvious on local ecosystems,” says Nicolas Cassar, a biogeochemist at Duke University, and an author on the paper....

They can also be customized to amplify different frequencies of sound depending on your hearing loss.

So what is color grading, exactly? Colorists are the people in post-production who take the footage and use color and contrast to make images pop. Manipulating a shot’s color can also create different emotional moods, heighten drama, and even convey physical sensations like cold nights or hot days. At the very least, a good colorist fixes problems in the footage resulting from mismatched lighting or exposure issues. All this is referred to as color grading....

Ski masks come in a variety of shapes and sizes. The most intense skiers will want as much face coverage as possible made from breathable materials that let you work up a sweat without overheating. For more casual trips, you may consider a ski mask that offers minimal coverage that still gets the job done while not being itchy, hot, or burdensome. Without proper protection, your ski trip can take a sharp turn for the worse with bad sunburns as a result of the high levels of UV radiation reflected in the snow or windswept dry skin....

The story of evolution got bigger last week when researchers revealed in the journal Science that they had discovered a wide-hipped pelvis, suggesting our ancestors were larger-brained than formerly thought. The first of its kind, the 1.2 million-year-old, near-complete female pelvis is from the now-extinct Homo erectus species, believed to be our first human-like relative to leave Africa. Previously, researchers postulated_ H. erectus_ females had narrower hips, consequently making it harder for them to give birth to larger-brained babies....

Ole Karsholt and Jan Pederson, both entomologists at the museum in Copenhagen, started collecting insects from the roof of the building in 1992.

Every week of every spring, summer, and fall, the two collected moths and beetles from a trap they had set up on top of the roof....

CAL Fire, California’s emergency response air program, is currently battling the explosive Kincade Fire in Sonoma County, which has burned 76,138 acres and was only 15 percent contained at press time. While that fire has destroyed 189 structures and damaged 39 other buildings, figures could have been much higher if not for the work of CAL Fire’s aerial firefighting assets and the brave pilots who fly them. In support of ground crews, the CAL Fire aerial firefighting fleet includes 21 Grumman S-2T airtankers, 10 UH-1H Super Huey helicopters, a King Air A200CT Air Attack aircraft and 14 OV-10A “observation” aircraft that operate from 13 statewide air attack and nine helitack bases....
