Giving fluorescence microscopy new power to study cellular transport

(Phys.org)—The ability of fluorescence microscopy to study labeled structures like cells has now been empowered to deliver greater spatial and temporal resolutions that were not possible before, thanks to a new method developed by University of Illinois researcher Gabriel Popescu and Ru Wang from his lab. Using this method, they were able to study the critical process of cell transport dynamics at multiple spatial and temporal scales and reveal, for the first time, properties of diffusive and directed motion transport in living cells.

Answer to energy transfer debate could impact areas from photovoltaics to quantum information

(Phys.org)—The transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. But an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer.

World record for entanglement of twisted light quanta

Physicists have achieved a new milestone in the history of quantum physics: Scientists were able to generate and measure the entanglement of the largest quantum numbers to date.<img src="http://feeds.feedburner.com/~r/sciencedaily/matter_energy/physics/~4/za-... height="1" width="1"/>

NASA'S Curiosity Rover Provides Clues to Changes in Martian Atmosphere

NASA's car-sized rover, Curiosity, has taken significant steps toward understanding how Mars may have lost much of its original atmosphere.

Spot The Space Station Over Your Backyard With New NASA Service

On the 12th anniversary of crews continuously living and working aboard the International Space Station, NASA announced Friday a new service to help people see the orbiting laboratory when it passes overhead.

Researchers find three unique cell-to-cell bonds

The human body has more than a trillion cells, most of them connected, cell to neighboring cells. How, exactly, do those bonds work? What happens when a pulling force is applied to those bonds? How long before they break? Does a better understanding of all those bonds and their responses to force have implications for fighting disease?

Particle and wave-like behavior of light measured simultaneously

What is light made of: waves or particles? This basic question has fascinated physicists since the early days of science. Quantum mechanics predicts that photons, particles of light, are both particles and waves simultaneously.

NASA Seeks Options For SLS Cargo Payload Fairings And Adapters

NASA is exploring options for larger payload fairings to enhance the cargo carrying capabilities of its Space Launch System (SLS) heavy-lift rocket, now in development, to carry cargo, crewed spacecraft and science payloads. In a Request for Information (RFI) published Thursday, the agency is seeking information about payload adapters and fairings already available within commercial industry.
