Impact glass stores biodata for millions of years

Asteroid and comet impacts can preserve the signatures of ancient life in Earthly impact debris. Researchers found fragments of leaves and preserved organic compounds in ancient impact glasses from Argentina, which could provide a snapshot of environmental conditions at the time of those impacts.

Ancient clam gardens nurture food security

Researchers discovered that ancient clam gardens made by Aboriginal people produced quadruple the number of butter clams and twice the number of littleneck clams as unmodified clam beaches. This study provides practical insights into sustainable ancient marine management techniques for local food security strategies.

Evolution stuck in slime for a billion years

Researchers in Tasmania reveal ancient conditions that stifled evolution for a billion years, but then oxygen levels surged, triggering the 'Cambrian explosion of life'. The study uses a new technique to analyze ancient seafloor rocks, shedding light on the emergence of life and its impact on Earth.

Man's best friend equally adapted to high altitudes of Tibet

A study published in Molecular Biology and Evolution found that Tibetan Mastiffs have undergone genetic adaptations to survive at high altitudes. The research identified 16 genes involved in energy production critical for high-altitude survival, suggesting convergent evolution between dogs and humans.

New method rescues DNA from contaminated Neandertal bones

A new statistical model has been developed to isolate ancient DNA from fossils contaminated with modern-day DNA. This method allows for the recovery of complete mitochondrial genomes from Neandertal and anatomically modern human bones, enabling scientists to study these individuals in detail.

A new scorpion species from ancient Lycia

A new scorpion species, Euscorpius lycius, has been discovered in the ancient Lycia region of Turkey, adding to the total of five known species within the genus. The newly found species is relatively small, ranging from 2-2.5 cm in length and has a pale color with darker pedipalps.

Ancient DNA unravels Europe's genetic diversity

A recent study reconstructed the first detailed genetic history of modern-day Europeans using ancient DNA from 364 prehistoric skeletons. The research found dramatic population changes with waves of migration from Western and Eastern Europe, contradicting previous assumptions about the Near East's role in shaping European genetics.

The final nail in the Jurassic Park coffin: Next generation sequencing reveals absence of DNA in sub-fossilized insects

A team of researchers from the University of Manchester used next generation sequencing techniques to analyze sub-fossilized insects in copal and found no evidence of ancient DNA. The study suggests that DNA survival in resin inclusions is unlikely, raising doubts about claims of DNA extraction from fossil insects in amber.

Ancient Egyptians accessorized with meteorites

Researchers have found conclusive proof that Ancient Egyptians used meteorites to create symbolic accessories. The evidence comes from a prehistoric iron bead discovered in Egypt, which was dated to around 3350-3600BC. Analysis of the bead's composition confirms its meteorite origins.

Feast clue to smell of ancient earth

Fossils from 1,900 million-year-old rocks in Lake Superior's Gunflint chert provide evidence of ancient heterotrophy. The team discovered microbes consumed other bacteria, producing a 'rotten egg' whiff similar to modern bacterial activity.

Ancient DNA solves 320-year-old mystery

Researchers from the University of Adelaide's Australian Centre for Ancient DNA extracted ancient DNA from two specimens and compared it to extinct relatives. They found that the Falkland Islands wolf diverged from its closest living relative around 16,000 years ago, revealing a 16,000-year-old island colonization process.

Ancient red dye powers new 'green' battery

Researchers from City College of New York have developed a non-toxic and sustainable lithium-ion battery powered by purpurin, a natural plant dye extracted from the madder plant. The battery's production process is simpler and less expensive than traditional Li-ion batteries, with fewer environmental risks.

Mining ancient ores for clues to early life

Scientists found that oxygen levels were extremely low on Earth 2.7 billion years ago, but also discovered microbes actively feeding on sulfate in the ocean during this period. The study provides new insight into ancient metal-ore deposits and their role in understanding early life evolution.

Ancient DNA sheds light on Arctic whale mysteries

Scientists have conducted the first range-wide genetic analysis of bowhead whales using ancient DNA samples from archaeological sites and modern populations. The study reveals differences in population diversity between ancient and modern times, suggesting recent disappearance of unique maternal lineages due to habitat loss and whaling.
