Altai Map

Di questo ominide sono stati rinvenuti pochissimi frammenti di ossa trovati nel 2008 nelle caverne di Denisova, nelle montagne Altai, nella Siberia meridionale, dai quali sono stati estratti campioni di Dna mitocondriale da cui e’ emerso che l’Homo siberianus e’ vissuto nell’Asia centrale fra 48.000 e 30.000 anni fa .

  • When it comes to how pizza looks, cheese matters
    Most consumers have an idea what they want their pizza slice to look like. Golden cheese with that dark toasted-cheese color scattered in distinct blistery patches across the surface with a bit of oil glistening in the valleys. A new study evaluated the pizza baking performance of different cheeses (mozzarella, cheddar, colby, Edam, Emmental, Gruyere, and pr […]
  • Hot-spring bacteria reveal ability to use far-red light for photosynthesis
    Bacteria growing in near darkness use a previously unknown process for harvesting energy and producing oxygen from sunlight, scientists have discovered. The discovery lays the foundation for further research aimed at improving plant growth, harvesting energy from the sun, and understanding dense blooms like those now occurring on Lake Erie and other lakes wo […]
  • Sunlight, not microbes, key to carbon dioxide in Arctic
    The vast reservoir of carbon stored in Arctic permafrost is gradually being converted to carbon dioxide after entering the freshwater system in a process thought to be controlled largely by microbial activity. However, researchers say that sunlight and not bacteria is the key to triggering the production of CO2 from material released by Arctic soils.
  • From dandruff to deep sea vents, an ecologically hyper-diverse fungus
    A ubiquitous skin fungus linked to dandruff, eczema and other itchy, flaky maladies in humans has now been tracked to even further global reaches -- including Hawaiian coral reefs and the extreme environments of arctic soils and deep sea vents. The study considers the diversity, ecology, and distribution of the fungi of the genus Malassezia in light of new i […]
  • How hummingbirds evolved to detect sweetness
    Hummingbirds' ability to detect sweetness evolved from an ancestral savory taste receptor that is mostly tuned to flavors in amino acids. Feasting on nectar and the occasional insect, the tiny birds expanded throughout North and South America, numbering more than 300 species over the 40 to 72 million years since they branched off from their closest rela […]
