Quantum Dots and Diffusion…

Topics: Biology, Diffusion, Quantum Dots, Quantum Mechanics Quantum dots diffuse within living cells in a nearly two-dimensional fashion. This result, which was obtained using a new 3D microscopy technique that can track single particles, sheds fresh light on intracellular diffusion – a process that is critical for moving molecules around the cell and for mediatingContinue reading “Quantum Dots and Diffusion…”

Blind Mice Seeing…

Topics: Bioengineering, Optical Physics, Nanorods, Nanotechnology Even in the dark, rattlesnakes and their fellow pit vipers can strike accurately at small warm-blooded prey from a meter away. Those snakes, and a few others, can see in the IR—but not with their eyes. Rather, they have a pair of specialized sensory organs, called pit organs, locatedContinue reading “Blind Mice Seeing…”

Lingering Effects…

Topics: COVID-19, Coronavirus, Pandemic I have friends who insist on seeing their friends during a pandemic, playing the equivalent of Russian Roulette (apropos, as they are capitalizing on our hubris), flaunting safety concerns and wearing masks “when they think about it” and selectively reading any materials I might send them. Well, I’ve attended at leastContinue reading “Lingering Effects…”

Gaming This Out…
