Study reveals how a popular fentanyl additive affects breathing and heart rate

A new U-M study found that xylazine does not amplify the decrease in breathing rate caused by fentanyl use, but reduces heart rate more than fentanyl. This reduction in heart rate may be a more important driver of increased overdose risk, highlighting the need for further research into polysubstance use involving opioids.

Microalgae are more significant for carbon dioxide absorption in the Southern Ocean than previously thought

A study by Alfred Wegener Institute revealed that microalgae in the Southern Ocean played a significant role in reducing global atmospheric CO2 levels 14,000 years ago. The findings suggest that changes in sea ice extent had a direct impact on algal productivity and carbon transport to the deep sea.

How cancer puts other cells to work

Researchers at ETH Zurich discovered that cancer cells can transfer their mitochondria to healthy fibroblasts, reprogramming them into tumour-associated fibroblasts that support cancer cell growth. The mitochondrial transfer mechanism involves the protein MIRO2, which is produced in high quantities in cancer cells.
