New Cornell research is providing a fresh view into the ways a common chemotherapy agent, etoposide, stalls and poisons the essential enzymes that allow cancer cells to flourish.
Conjugated polymers are essentially clusters of molecules strung along a backbone that can conduct electrons and absorb light. This makes them a perfect fit for creating soft optoelectronics, such as ...

Effect of Ethylene Treatment on Germination of Tweezers Harvested Seeds of Two Strawberry Cultivars
Ethylene Treatment Germination Tweezers Harvested Seeds
2009/7/13
The effect of ethylene treatment on the germination of tweezers-harvested seeds was examined in two strawberry cultivars, ‘Sachinoka’ and ‘Asuka-ruby’. In both cultivars, seeds treated with 100, 200, ...
On-demand Optical Tweezers Using Computer-generated Phase Holograms
Holographic optical tweezers Spatial light modulator Time-multiplexing

Effect of pentoxifylline on the intrinsic swimming forces of human sperm assessed by optical tweezers
pentoxifylline intrinsic swimming forces human sperm optical tweezers
2008/12/25
It is still controversial whether in vitro exposure of sperm to pentoxifylline increases sperm motility and force, which is defined as the product of velocity by beat frequency of the tail. Laser ...
