Imaging glucose uptake activity inside single cells

A new approach to visualize glucose uptake activity in single living cells has been developed by Columbia University researchers. This technique uses stimulated Raman scattering imaging with a small alkyne tag to generate a strong Raman signal, allowing for high-sensitivity imaging of glucose uptake at the cellular level.

Marine plankton brighten clouds over Southern Ocean

New research reveals that marine plankton in the Southern Ocean produce airborne gases and organic matter to seed cloud droplets, leading to brighter clouds. The study found correlations between phytoplankton blooms and increased cloud droplet concentrations, which reflect about 4 watts of solar energy per square meter.

Diarrhea in cats

A study found that intestinal parasites, such as Giardia, were the most commonly found parasite in cats across Austria, with over 56% testing positive. The parasites can be transmitted through contact with infected cat faeces, and households with multiple cats are at higher risk.

Bringing back the magic in metamaterials

Scientists have made significant progress in overcoming the challenges of creating a perfect lens using metamaterials. The team proposes a novel approach that utilizes negative index materials and plasmon-injection schemes to shield desired light waves, allowing them to pass through unscathed. This breakthrough has the potential to rev...
