Rocky hitchhikers: hardy microbes may shuttle life between planets

A Johns Hopkins-led study shows the bacterium Deinococcus radiodurans can survive pressures up to about 1.4–2.4 gigapascals from simulated asteroid impacts, lending support to lithopanspermia—the idea that microbes could hitchhike on rock fragments between planets. While not proof that life transferred from Mars to Earth or vice versa, the findings suggest microbes could endure interplanetary transfer, potentially prompting reevaluation of planetary-protection rules.

Engineer and Poet Collaborate to Encode Poetry into Living Bacteria

Scientists have engineered a bacterium to encode and recite poetry by embedding a poem into its DNA, which also causes the bacterium to glow red when activated. This innovation aims to preserve cultural messages across geological timescales and has potential applications in long-term data storage and synthetic biology.

Unveiling the Secret Behind Radiation-Resistant 'Conan the Bacterium'

Scientists have discovered that the bacterium Deinococcus radiodurans, known for its extreme radiation resistance, owes its resilience to a powerful antioxidant composed of manganese, phosphate, and a peptide. This discovery could lead to the development of radioprotective measures for astronauts and applications on Earth. The study highlights the potential of using this antioxidant to protect against cosmic radiation during deep-space missions and radiation exposure on Earth.

Scientists Uncover How a Microbe Thrives on Radiation, Offering Hope for Space Travel

Researchers have uncovered the secret behind the radiation resistance of the microbe Deinococcus radiodurans, known as 'Conan the Bacterium.' The microbe's resilience is attributed to a potent mix of antioxidants, particularly a manganese-phosphate-peptide complex, which effectively neutralizes harmful oxygen radicals. This discovery could lead to the development of advanced radioprotectants for various applications, including healthcare and space exploration.
