A new virtual approach to science in space
Tempe AZ (SPX) Jun 23, 2017
When Apollo astronauts on the Moon spoke with Mission Control on Earth, there was a noticeable time gap between a statement from Tranquility Base and its immediate acknowledgment from Houston. The gap lasted almost three seconds, or ten times longer than human reaction times would account for. What was happening? The answer is simple: space. The Moon orbits far enough from Earth that light (and radio) take 1.3 seconds each way to travel the distance. At exploration targets farther away, the delay ... read more

Helium droplets offer new precision to single-molecule laser measurement
Chemical reactions necessarily involve molecules coming together, and the way they interact can depend on how they are aligned relative to each other. By knowing and controlling the alignment of mol ... more
New computing system takes its cues from human brain
Some problems are so challenging to solve that even the most advanced computers need weeks, not seconds, to process them. Now a team of researchers at Georgia Institute of Technology and Unive ... more
Magnetic space tug could target dead satellites
Derelict satellites could in future be grappled and removed from key orbits around Earth with a space tug using magnetic forces. This same magnetic attraction or repulsion is also being consid ... more
Recycled tires create stronger concrete
UBC engineers have developed a more resilient type of concrete using recycled tires that could be used for concrete structures like buildings, roads, dams and bridges while reducing landfill waste. ... more
Scientists develop molecular code for melanin-like materials
Scientists have long known that melanin - the pigments that give color to skin, hair and eyes - has numerous useful qualities, including providing protection from cancer-causing UV radiation and fre ... more
Beetles spark development of color-changing nanoparticles for commercial use
Inspired by the varying colors that gleam off of beetle shells, scientists have developed color-shifting nanoparticles that can change hue even after being embedded into a material. A report on the ... more
Artificial cartilage under tension as strong as natural material
Biomedical engineers at the University of California, Davis, have created a lab-grown tissue similar to natural cartilage by giving it a bit of a stretch. The tissue, grown under tension but without ... more
