BIOLOGY
 
Genetic Geometry Takes Shape
 
Inside the cell’s nucleus, the double helix folds up in myriad loops and twists. The quest to unravel this structure is revealing the subtle genetic orchestration of all life on Earth.

"The nuclei from a half-million human cells could all fit inside a single poppy seed. Yet within each and every nucleus resides genomic machinery that is incredibly vast, at least from a molecular point of view. It has billions of parts, many used to activate and silence genes — an arrangement that allows individual cells to specialize as brain cells, heart cells and some 200 other different cell types. What’s more, each cell’s genome is atwitter with millions of mobile pieces that swarm throughout the nucleus and latch on here and there to tweak the genetic program. Every so often, the genomic machine replicates itself."

"Hummingbird tongues are tiny pumps that suck up nectar—not merely passive strawlike structures as long thought, new research suggests. In a few studies of lab-reared hummers, scientists noted that the birds sometimes used capillary action—the tendency of a liquid to be pulled into a narrow space, even upward against gravity ..."

Atacama Desert Blooms Pink After Historic Rainfall (Photos)
 
by Tia Ghose, Senior Writer   |   October 29, 2015 12:07pm ET
 
"The Atacama Desert, one of the driest places on Earth, is experiencing a riot of color as a rare springtime bloom of flowers covers every hillside.
 
The explosion of color is the result of rains that swept through the region earlier this year, watering seeds that had lain dormant in the ground for years.
 
The Atacama Desert typically gets just 0.6 inches (15 millimeters) a year in rainfall, though some places in the region, such as Arica, receive even less, experiencing between 0.04 and 0.12 inches (1 and 3 mm) of rain a year."

Video: Infrared Movies Capture Hummingbirds Shedding Heat in Flight

 

By Claire Asher 15 December 2015 7:15 pm
 
"Hummingbirds are impressive flyers, managing 12 meters and 50 wingbeats per second. But all that flapping could put them in danger of overheating. Research published online today in Royal Society Open Science shows ..."
