Ciprofloxacin has dramatic effects on the mitochondrial genome

A study investigated the effect of ciprofloxacin on mitochondria, the important cell organelles in our body that produce the energy for cellular function. Ciprofloxacin stopped normal maintenance and transcription of mitochondrial DNA by changing mtDNA topology, causing impaired mitochondrial energy production and blocking cellular growth and differentiation.

How lactoferrin clamps down on free roaming iron ions to stop nefarious effects on cells

What prevents our cells being damaged due to overexposure to iron ions is a protein called lactoferrin, known for its ability to bind tightly to such ions. Researchers used a combined experimental and molecular dynamics simulation to study the changes in the structure of lactoferrin as it binds to iron ions.

Study shows toxic effects of oil dispersant on oysters following deepwater horizon spill

A new study finds that oysters likely suffered toxic effects from the oil dispersant Corexit® 9500 when it was used to clean up the 2010 Deepwater Horizon oil spill. Researchers determined this by comparing the low levels of toxicity of oil, the dispersant and a mixture of the two on Eastern oysters.

Estimating global agricultural effects of geoengineering using volcanic eruptions

Estimating global agricultural effects of geoengineering using volcanic eruptions, Published online: 08 August 2018; doi:10.1038/s41586-018-0417-3

Analysis of the El Chichón and Mount Pinatubo volcanic eruptions suggests that solar radiation management strategies using stratospheric sulfate aerosols would do little to counterbalance the effects of climate change on global crop yields.
