Researchers manage to extend the field of view for speckle-correlation imaging under a limited memory effect
Trying to see through scattering media like haze and fog is often accompanied by disappointment or even difficulties in our daily lives—if you have ever experienced a sunrise-watching trip on a cloudy morning or a palm-sweating drive through dense.....»»
Mineral soil in forests accumulates carbon as trees grow
A recent study by the Natural Resources Institute Finland (Luke) investigated the accumulation of soil carbon in forest sites monitored intensively in the long term. In mature spruce- and pine-dominated forests where the growing stock volume increase.....»»
Flies smell the motion of odors and use it to navigate, study finds
The survival of all animals and insects, from wolves to bees, depends upon their ability to find the source of odors, which is a challenge when wind disperses and obscures their source. Past research has shown that animals and insects navigate their.....»»
