Cave cyanobacteria harness near-infrared light, expanding the search for life in the cosmos

Scientists exploring Carlsbad Caverns in New Mexico found cyanobacteria on cave walls that can photosynthesize using near-infrared light thanks to chlorophyll d and f, enabling energy capture in darkness and in cave zones possibly untouched for about 49 million years. This widens the known range of photosynthesis, implying red-dwarf–type stars could host life and helping to refine the search for habitable exoplanets with JWST by focusing on longer wavelengths and lower light levels where oxygen could signal life.

Mysterious Martian Hole May Be Vital for Future Astronaut Survival

Scientists have discovered a mysterious hole on Mars that could be a skylight leading to lava tubes, which may serve as protective habitats for future human explorers by shielding them from radiation and harsh environmental conditions. The hole's exact nature is still under investigation, but it represents a promising avenue for exploring underground refuges on Mars, similar to lunar lava tubes, and could be crucial for sustainable colonization.

NASA Discovers Moon Cave Ideal for Future Human Base

Scientists have discovered a 100m deep cave on the Moon, which could potentially serve as a site for a permanent human base. The cave, located in the Mare Tranquillitatis, was identified using radar and offers protection from radiation, extreme temperatures, and space weather. Researchers believe this discovery could also aid in exploring caves on Mars and provide insights into the Moon's geological history.

"Homeless Californians Discovered Living in Underground Caves with Furnishings"

Homeless individuals in California were discovered living in furnished caves along the Tuolumne River, prompting a joint cleanup effort by the Modesto Police Department, volunteers, and local organizations. The caves, located 20 feet below street level, were found to be fully furnished and contained significant amounts of garbage, drugs, and weapons. This discovery highlights the growing homelessness crisis in California, with Los Angeles also mobilizing thousands of volunteers to conduct a street tally to address the surging homeless population.

"Hidden Homeless: California's Subterranean Caves Sheltering Drug-Infested Furnished Dwellings"

Homeless individuals in California were discovered living in 20-foot-deep caves along the Tuolumne River in Modesto, furnished with furniture and supplies. Police and volunteers removed 7,600 pounds of trash from the makeshift dwellings, which were accessed by makeshift stairs carved into the hillside. Concerns have been raised about the safety of the residents, and efforts are being made to relocate them to proper housing.

"Mastering LEGO Fortnite: A Comprehensive Guide to Tools, Weapons, Resources, and Maps"

Finding caves in Lego Fortnite can be challenging but rewarding. Caves offer resources and can be accessed early in the game. They are not marked on the map, so players must look for cave outcroppings with a mass of rocks. Interacting with the cave entrance loads players into the cave. Once discovered, caves are marked on the map. Specific seed codes can be used to access worlds with identifiable caves. Caves function as dungeons with resources to farm, but also enemies to fight. Players should craft a shortsword and can bring a villager ally for support. Caves contain chests with various resources, but these do not respawn.

Unearthing Utah's Hidden Wonders: The Power of Citizen Scientists

Scientists from the Natural History Museum of Utah collaborated with Utah's caving community to explore caves and uncover skeletal remains of mammals, providing insights into the recent past. The research, published in the Journal of Mammalogy, utilized caves as research archives to understand mammalian diversity and changes in alpine ecosystems. The discovery of fossils spanning the past 3,000 years, including previously unknown species, highlights the value of collecting skeletal remains from caves for zoological census and long-term records. This collaborative effort demonstrates the importance of citizen science in scientific research.

"Mars' Ancient Caves: A Potential Haven for Extraterrestrial Life?"

Scientists are exploring the possibility of finding life on Mars in ancient caves and lava tubes. These underground structures could have provided a more hospitable environment for life when Mars had flowing water, a warmer climate, and an atmosphere. By studying extreme conditions in caves on Earth, researchers hope to gain insights into what life may look like in similar conditions elsewhere in the solar system. Microbes found in lava tubes in Hawaii have shown the ability to thrive by drawing nutrients from rocks, suggesting that similar microbes could have existed or may still exist on Mars. The search for life in Martian caves continues, with plans to explore lava tubes on the Moon as well.
