Hot Topic Origins Origin & Evolution of Life
Ancient Sea Creatures Yield Oldest Fossil Biomolecules
Topic: Origin & Evolution of Life
Summary: Scientists have found 350-million-year-old fossils that contain intact organic molecules sealed in their pores. Prior to this discovery, it was thought that complex organic molecules couldn't survive fossilization.

Stay Cool, Live Longer?
Topic: Origin & Evolution of Life
Summary: A new study could suggest that exposure to cold air may promote longevity in mammals.

Self-Assembling Molecules May Point to Life's Origin
Topic: Origin & Evolution of Life
Summary: Scientists have reported that a pair of RNA-like molecules can spontaneously assemble into gene-length chains. A similar process may have led to the evolution of RNA and life itself billions of years ago.

Salmon May Use Magnetic Field to Navigate
Topic: Origin & Evolution of Life
Summary: A new study shows that salmon may use the geomagnetic field to navigate across thousands of miles of open ocean to locate their river of origin.

Dung Beetles of the Stars
Topic: Origin & Evolution of Life
Summary: Scientists have proven that dung beetles use the Milky Way for orientation. The insects use the gradient of light to dark in the night sky to guide them as they roll their balls in a straight line.

When Living Cells Meet Synthetic Proteins
Topic: Origin & Evolution of Life
Summary: A new paper describes the peculiar adaptations exhibited by the bacterium E. coli when cells are exposed to a synthetic protein. The study is helping scientists understand how synthetic biology could be beneficial in areas such as medicine.

'Quadruple Helix' DNA Discovered in Humans
Topic: Origin & Evolution of Life
Summary: Researchers have proved that four-stranded 'guadruple helix' DNA structures exist within the human genome. The finding could have implications in the treatment of cancer.

Tracking the Great Oxidation Event
Topic: Origin & Evolution of Life
Summary: A new study shows that multicellular cyanobacteria arose much earlier than previously believed. Multicellularity developed in cyanobacteria at almost the same time as the oxygenation of Earth's atmosphere, and around one billion years earlier than eukaryotes.

Bubbling Organics in an Ocean Vent Simulator
Topic: Origin & Evolution of Life
Summary: Astrobiologists have built a series of glass tubes and valves with a laser and a detector system that mimics the conditions at hydrothermal vents. The system detects compounds coming from the simulated vent and will help determine if biologically important molecules are being formed.

Origin of Life May Have Emerged From Bioenergetics
Topic: Origin & Evolution of Life
Summary: For the first time, scientists have traced a pathway that leads from rocks, water and carbon to the emergence of the strange bio-energetic properties of living cells.
