Zombie cells in the sea: Viruses keep the most common marine bacteria in check      (via sciencedaily.com)     Original source 

Marine microbes control the flux of matter and energy essential for life in the oceans. Among them, the bacterial group SAR11 accounts for about a third of all the bacteria found in surface ocean waters. A study now reveals that at times nearly 20% of SAR11 cells are infected by viruses, significantly reducing total cell numbers. The viruses can also transform these once thriving bacteria into zombies, a phenomenon observed for the first time and widespread in the oceans.

Plants restrict use of 'Tipp-Ex proteins'      (via sciencedaily.com)     Original source 

Plants have special corrective molecules at their disposal that can make retrospective modifications to copies of genes. However, it would appear that these 'Tipp-Ex proteins' do not have permission to work in all areas of the cell, only being used in chloroplasts and mitochondria. A study has now explained why this is the case. It suggests that the correction mechanism would otherwise modify copies that have nothing wrong with them, with fatal consequences for the cell.

Deep-sea sponge's 'zero-energy' flow control could inspire new energy efficient designs      (via sciencedaily.com)     Original source 

The deep-sea Venus flower basket sponge can filter feed using only the faint ambient currents of the ocean depths, no pumping required, new research reveals. This discovery of natural 'zero energy' flow control could help engineers design more efficient chemical reactors, air purification systems, heat exchangers, hydraulic systems, and aerodynamic surfaces.

Early arrival and expansion of palaeolithic people on Cyprus      (via sciencedaily.com)     Original source 

The patterns of dispersal of early humans across continents and islands are hotly debated, but researchers have found that Pleistocene hunter-gatherers settled in Cyprus thousands of years earlier than previously thought. In examining the timing of the first human occupation of Cyprus, research found that large islands in the Mediterranean Sea were attractive and favorable destinations for palaeolithic peoples. These findings refute previous studies that suggested Mediterranean islands would have been unreachable and inhospitable for Pleistocene hunter-gatherer societies.

A powerful tool speeds success in achieving highly efficient thermoelectric materials      (via sciencedaily.com)     Original source 

Thermoelectric materials could play an important role in the clean energy transition, as they can produce electricity from sources of heat that would otherwise go to waste. Researchers report a new approach to efficiently predict when thermoelectric materials will have improved performance in converting heat into electricity.

Airborne technology brings new hope to map shallow aquifers in Earth's most arid deserts      (via sciencedaily.com)     Original source 

The new technique will map the top of the aquifer, called the 'water table,' spanning areas as large as hundreds of kilometers using a radar mounted on a high-altitude aircraft. According to the researchers, Desert-SEA will measure the variabilities in the depth of the water table on a large scale, allowing water scientists to assess the sustainability of these aquifers without the limitations associated with in-situ mapping in harsh and inaccessible environments.
