Carbon Dioxide is Actually Good for Your Cells
A groundbreaking study by University of Utah chemists reveals a surprising benefit of carbon dioxide (CO₂) for cellular health. While CO₂ is notorious for its role in climate change, this study highlights how bicarbonate, derived from CO₂, acts as a buffer within cells to protect DNA from oxidative stress—a process linked to aging, cancer, and various diseases.
Under stress, cells produce hydroxyl radicals that wreak havoc on DNA. However, when bicarbonate is present, the reaction shifts, forming milder radicals that target specific genetic sites, minimizing damage. This discovery could reshape how oxidative stress is studied, as many past experiments excluded bicarbonate, potentially skewing results.
The implications are vast, from improving laboratory methods to exploring the protective role of CO₂ in environments like space capsules, where astronauts face radiation risks. Could a slight increase in CO₂ levels shield cells from damage in extreme conditions? This study opens up exciting avenues for future research.

Phages: A Targeted Antibiotic Alternative
With antibiotic resistance on the rise, phage therapy—a once-forgotten treatment—may offer new hope. Scientists at the Institut Pasteur and collaborators have developed an innovative AI model that tailors phage combinations to specific bacterial infections. Phages are viruses that exclusively target bacteria, making them a precise alternative to antibiotics.
By analyzing the genome of bacterial strains like Escherichia coli, the AI predicts which phages will be most effective. In trials, the AI-selected phage cocktails succeeded in eliminating antibiotic-resistant bacteria in 90% of cases.
This breakthrough paves the way for personalized phage therapy to tackle superbugs and could revolutionize treatments for multidrug-resistant infections in hospital settings. Researchers aim to expand the method to combat other harmful bacteria in the future.

How Cancer Cell Death Can Backfire on the Immune System
New research from Moffitt Cancer Center reveals a surprising twist in cancer treatment. When cancer cells die through necroptosis, a process thought to boost immunity, they release interleukin-1α, a molecule that suppresses immune responses and aids tumor growth. This explains why some treatments, like chemotherapy, may fall short. The study shows that blocking interleukin-1α can strengthen the immune system, improve chemotherapy and immunotherapy effectiveness, and even reduce treatment toxicity. These findings could pave the way for more effective cancer therapies and personalized treatment approaches.
