In the desert areas of Namibia, Oman, and Saudi Arabia, research work has revealed unusual structures that are probably due to the activity of an unknown microbiological life form. Unusually small burrows, i.e., tiny tubes that run through the rock in a parallel arrangement from top to bottom, were discovered in marble and limestone of these desert regions.

An analysis of a 30,000-year-old fossil vulture from Central Italy has revealed for the first time that volcanic rock can preserve microscopic details in feathers - the first ever record of such a preservation.

An international team, led by Dr Valentina Rossi (University College Cork, Ireland), discovered a new mode of preservation of soft tissues that can occur when animals are buried in ash-rich volcanic sediments.

The new research, published in the scientific journal Geology, reveals that the feathers are preserved in a mineral phase called zeolite, a mode of preservation of soft tissues never reported before.

New research reveals that heavy precipitation sourced from the Atlantic Ocean, are the primary drivers of present-day lake filling in the northwestern Sahara. The study finds that only the most intense and prolonged precipitation events trigger lake-filling episodes, challenging long-standing assumptions about past climate conditions in the region. These findings suggest that projections of enhanced rainfall intensity and frequency in the Sahara could potentially reshape water availability in the desert.

A team from the Marine Biological Laboratory, Woods Hole, studied the sediments that Hurricanes Fabian (2003) and Igor (2010) transported from the Bermuda carbonate platform -- a shallow-water reef refuge for marine life – and deposited to the deep ocean. They found significant effects on the deep ocean environment that lasted for weeks. Hurricane Fabian delivered as much sediment to the deep ocean in just two weeks as would normally take a full year to accumulate. These sediments -- carbonate-rich material that forms in the thriving ecosystem on reef platforms -- have major effects on the ocean environment. If they get buried in deep sediments, they can sequester carbon for millennia or more. They can also provide a buffering effect to help offset ocean acidification, a consequence of rising atmospheric CO₂ concentrations. The scientists, from the MBL's Oceanic Flux Program, published their data in Journal of Geophysical Research - Oceans.
