    Austria’s Glaciers Face Record Melting
    31.07.2025
    exposed ice costs about ten centimeters of thickness. The longer this phase lasts, the greater the melt. What matters is not the valley temperature, but whether the ice above is uncovered – since around 70 percent of the melt energy comes from solar radiation, not air temperature. Recently, the freezing level has been very high, with temperatures above zero even at high altitudes. This means melting continues at night – the glaciers are melting practically around the clock. ...

    Roman time capsule at the bottom of the sea
    25.04.2019
    time capsules - you can discover what was transported and where it was produced. Can you still tell what was in the amphorae? González Cesteros: Yes, some are even still sealed with their contents untouched. On board the wreck there are three different types of amphorae. All come from Andalusia, from the then Roman province of Baetica, and each has its own content. One contains, for example, salted pieces of fish or fish sauce. But we do not know everything yet. We have only ...

Together with an international research team, she is investigating the three sites of Bushman Rock Shelter, Rose Cottage Cave and Sibhudu Cave in the Republic of South Africa. The three sites are located in three different vegetation zones and in regions that have so far been little explored. Viola Schmid: "All three sites show cultural layers from the so-called Middle Stone Age of marine isotope stage 5, which includes the time from ...

    resulting “dressed electron” can be theoretically described as quasiparticle or a polaron. “You could picture it as a skier on a powder day,” says Grimm. “The skier is surrounded by a cloud of snow crystals. Together they form a system that has different properties than the skier without the cloud.” The challenge in an experiment is to measure the quasiparticles. “These processes last only attoseconds, which makes a time-resolved observation of their formation extremely ...

    Gold from Troia, Poliochni and Ur had the same origin

    able to prove that workshops produced jewellery in series and not just as individual pieces. There is no other explanation, for example, for the identical proportion of platinum and palladium in the gold plates of necklaces of the same type that were found in different places. The research team examined a total of 61 artefacts, all of which date back to the Early Bronze Age between 2,500 and 2,000 BC. This period also includes the famous "Treasure of Priam", which Schliemann ...

This is a great example how different fields of research, working together, can make novel discoveries at the interfaces of different kinds of biology”’ says Harvard’s Clifford Woolf. “In our case, a molecule recognized as essential for many functions in neurobiology, is now identified as key for ...

They screened current anti-diabetic medications, none of which had any positive effects on these blood vessel defects, as well as multiple small-molecule inhibitors of different signaling ...

The special thing about our method is that we analyze the sequence of the virus directly. How is this different to conventional PCR tests? Elling: Conventional methods require expensive light probes and so-called qPCR machines (quantitative PCR machines), which are currently not available on the market in large quantities. The ...

    “Kipferl”: Guiding the defense against jumping genes
    04.10.2022
    from the Institute of Molecular Biotechnology of the Austrian Academy of Sciences (IMBA) describe how different types of repetitive DNA elements are controlled by the same silencing mechanism in fruit fly ovaries. Central to their findings is an uncharacterized protein that the researchers named “Kipferl”, which ensures the effective control of jumping genes. The findings suggest that different selfish elements compete for the host genome defense system and that Kipferl ...

During evolution, existing structures are frequently duplicated and then converted into something new that could be useful. “Our findings present a remarkable example of ‘adaptive radiation’ at the protein level. Two copies of ...
