UNIVERSITY PARK, Pa. — Infection with dengue virus makes mosquitoes more sensitive to warmer temperatures, according to new research led by Penn State researchers. The team also found that infection with the bacterium Wolbachia, which has recently been used to…
(University of Pittsburgh) Contrary to popular belief, early bacterial evolution is not driven by random-point mutations.
(Trinity College Dublin) A team of geneticists and archaeologists from Ireland, France, Iran, Germany, and Austria has sequenced the DNA from a 1,600-year-old sheep mummy from an ancient Iranian salt mine, Chehrābād. This remarkable specimen has revealed sheep husbandry practices of the ancient Near East, as well as underlining how natural mummification can affect DNA degradation.
(Max Planck Institute for Marine Microbiology) This pandemic year has restricted us from travelling the globe. Not so for some microscopic bacteria in the ocean: They partner up with clams living in the sand beneath the shimmering waters of coastal habitats throughout the globe. According to research by scientists from the Max Planck Institute for Marine Microbiology in Bremen and the University of Vienna now published in PNAS, the bacterial symbionts living in lucinid gills travel the world without borders.
Antarctica has hidden lakes: Scientists find water system formed by melting ice due to global warming – India Today
The Antarctic ice sheet, which appears calm and stable from above, is slowly losing its foundation and collapsing under its own weight as global warming and climate change raise temperatures on the poles. The melting of water has created several…
(NASA/Goddard Space Flight Center) From above, the Antarctic Ice Sheet might look like a calm, perpetual ice blanket that has covered Antarctica for millions of years. But the ice sheet can be thousands of meters deep at its thickest, and it hides hundreds of meltwater lakes where its base meets the continent’s bedrock. Deep below the surface, some of these lakes fill and drain continuously through a system of waterways that eventually drain into the ocean.

(Max Planck Institute for Marine Microbiology) Hot vents in the deep sea are home to microbes that feed on ethane. They were discovered recently from scientists of the Max Planck Institute for Marine Microbiology. Now the researchers from Bremen succeeded in finding an important component in the microbial conversion of the gas. They were able to decode the structure of the enzyme responsible for the ethane fixation. The results have now been published in the renowned journal Science.
(University of Oldenburg ) The depths of the Black Sea store comparatively large amounts of organic carbon. A research team led by scientists from the University of Oldenburg, Germany, has now presented a new hypothesis as to why organic compounds accumulate in this semi-enclosed sea and other oxygen-depleted waters. Reactions with hydrogen sulfide play an important role in stabilizing carbon compounds, the researchers posit in the scientific journal Science Advances. This negative feedback in the climate system could counteract global warming over geological periods.
