Scientists studied how a dangerous fungus called Cryptococcus neoformans behaves in space-like conditions. They found that in simulated microgravity, the fungus becomes more dangerous by developing thicker protective capsules and producing more melanin, while also becoming more resistant to certain stresses. Interestingly, the fungus became more sensitive to one antifungal drug but maintained resistance to others. When tested on microscopic worms, the fungus grown in simulated microgravity killed them more quickly, suggesting space conditions could make this fungus more harmful to astronauts.
