Comparative Genomics and Phylogenomics of Novel Radiation-Resistant Bacterium Paracoccus qomolangmaensis sp. nov. S3-43T, Showing Pyrethroid Degradation

mycolabadmin

Scientists discovered a new type of bacteria called Paracoccus qomolangmaensis living on Mount Everest at extreme altitude where radiation is 10-20 times stronger than at sea level. This remarkable bacterium can survive intense radiation, oxidative stress, and can degrade harmful pesticides called pyrethroids. The bacteria’s genome contains special genes for repairing DNA damage and protecting itself from oxidative stress, making it a valuable resource for understanding how life survives in extreme conditions and potentially cleaning up pesticide contamination.

Transcriptom Analysis of Auricularia auriculla-judae Fruit Body Treated with Gamma Radiation on Mycelium

mycolabadmin

Researchers studied how the wood ear mushroom (Auricularia auricula-judae) responds to gamma radiation at the genetic level. They found that when exposed to radiation, the mushroom activates DNA repair mechanisms and eliminates damaged cells through cell death, rather than relying on antioxidant defenses like some other fungi. This research helps us understand how edible mushrooms naturally protect themselves from radiation damage.

Sustainable memristors from shiitake mycelium for high-frequency bioelectronics

mycolabadmin

Scientists have discovered that shiitake mushrooms can be grown into computer memory devices called memristors. These fungal memristors work similarly to brain neurons, can be dried and stored for later use, and operate reliably at high speeds. Because they use common, biodegradable mushrooms instead of rare minerals, they offer an environmentally friendly alternative for computing that could be used in spacecraft and other advanced applications.
