Ginkgo fossil. Credit: Stephen McLoughlin For the first time, researchers have succeeded in establishing the relationships between 200-million-year-old plants based on chemical fingerprints. Using infrared spectroscopy and statistical analysis of organic molecules in fossil leaves, they are opening up new perspectives...
Methane hydrate recovered from ocean sediments off Svalbard dissociates into water and methane gas under surface pressure and temperature conditions, allowing the methane released to be lit on fire. Credit: Image courtesy of National Oceanography Centre Methane seeps from seafloor deposits...
The white calcite 'veins' of the Loma Blanca fault are evident in this slab of rock on the fault. These veins of calcite reveal a record of fluid-driven earthquakes clustered together on a fault typically characterized by less frequent,...
The naked HIV capsid, left, would be quickly detected and eliminated from the cell, but a host protein, cyclophilin A, in red in the image on the right, binds to the capsid and enables it to transit through the...

Mars: Not as dry as it seems

0
This is image shows modern Mars (left) dry and barren, compared with the same scene over 3.5 billion years ago covered in water (right). The rocks of the surface were slowly reacting with the water, sequestering it into the...
