A new study reveals hydrogen gas’s role as an energy source at life’s dawn, underscoring its potential as a sustainable fuel. Through examining the natural processes at hydrothermal vents and…
…the course of one’s life ― where happiness increases into middle age, and then declines in later life. Understanding the variability of subjective well-being across humanity is important, Gurven said,…
…existence of how life forms, but also gives us clues for how long our own civilization will last. If we find that intelligent life is common then this would reveal…
…plausible prebiotic setting. Before life emerged on Earth, many physicochemical processes on our planet were highly chaotic. A plethora of small compounds, and polymers of varying lengths, made up of…
…disks around young stars, suggesting that life’s chemical ingredients may be widespread in the universe. Analysis of unique fingerprints in light emitted from material surrounding young stars has revealed “significant…
…of life – in Martian rocks. “Total organic carbon is one of several measurements [or indices] that help us understand how much material is available as feedstock for prebiotic chemistry…
…about the origin of life.” As early as the 18th and 19th centuries, scientists were convinced that meteorites brought the “elements of life,” as Walton calls them, to Earth. Even…
…system to look for life, and we think life needs water. So we need robots that can explore those environments — autonomously, hundreds of millions of miles from home,” said…
…conditions differ from Earth’s. Many are tidally locked, meaning the same side always faces their star while the other faces away. “If photosynthetic life evolved on these planets, that life…
Newly described chemical reaction could have assembled DNA building blocks before life forms and their enzymes existed. Discovery boosts theory that life on our planet arose from RNA-DNA mix. Chemists…

…gathered at NASA Headquarters to discuss the next steps to finding life beyond Earth, and outlined NASA’s roadmap to the search for life in the universe. Many scientists believe we…
…the origins, diversification, and extinction of ancient life. With this new study, the chart of life now includes life forms from the Proterozoic Eon, 2,500 million to 539 million years…
…potential birthplace of life during the Hadean era. Insights from a University of California study suggest that early Earth had liquid water and conditions that might have supported life’s beginnings,…
…the Earth’s history, life has existed only as microbial life,” said Max Coleman, senior research scientist at JPL. “On Europa, the best chance for life would be microbial.” The particular…
