Climate scientists have discovered a new archive of historical sea temperatures. With the help of the skeleton of a sponge that belongs to the Monorhaphis chuni species and that lived for 11,000 years in the East China Sea an international team around scientists from the Max Planck Institute for Chemistry could show that the deep ocean temperature changed several times over the past millennia.
Microscopic image of a glass sponge. The image shows a one millimeter cross section of the skeleton of Monorhaphis chuni. The lamellae grew inside outwards during the 11,000 years. The chemical elements incorporated during this period show that the water temperature in its environment changed significantly several times. Picture: Werner E. G.

As isotopic and elemental analyses showed, the sea water temperature in the vicinity of the sponge increased at least once from less than two degrees Celsius to six to ten degrees Celsius. These temperature changes were not previously known and are due to eruptions of seamounts.The deep sea is full of unknown creatures, but it is new to find one with which one can trace back thousand years of climate changes. Researchers at the Max Planck Institute for Chemistry in Mainz have now determined the age of a more than two meters long and one centimeter thick glass sponge to be about 11,000 years. It is among the longest living animal species that exist today. From this animal`s skeleton the researchers can also read how its environment and the climate changed during its life.

Scientists have developed a new method of characterizing graphene’s properties without applying disruptive electrical contacts, allowing them to investigate both the resistance and quantum capacitance of graphene and other two-dimensional materials. Researchers from the Swiss Nanoscience Institute and the University of Basel’s Department of Physics reported their findings in the journal Physical Review Applied.
Graphene consists of a single layer of carbon atoms. It is transparent, harder than diamond and stronger than steel, yet flexible, and a significantly better...
The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
