Chemists discover new reactivity of strained molecules

In synthetic organic chemistry, so-called cycloadditions are a particularly important class of reactions. With this type of reaction, ring-shaped molecules can be constructed simply and efficiently by joining ("adding") two ...

First 3D structure of regulator protein revealed

Proteins are indispensable components in living organisms. They are not only "building material" for the body—they also make molecular communication between cells possible, they are needed for nerve impulses to occur, and ...

Earth and Mars were formed from inner solar system material

Earth and Mars were formed from material that largely originated in the inner solar system; only a few percent of the building blocks of these two planets originated beyond Jupiter's orbit. A group of researchers led by the ...

Examining the neurotoxin from a black widow

Phobias are often irrational by nature—especially in the case of spiders, as these creatures are usually more afraid of humans than vice-versa. But: some species are a force to be reckoned with—for example, the Latrodectus ...

Studying cosmic expansion using methods from many-body physics

It is almost always assumed in cosmological calculations that there is a even distribution of matter in the universe. This is because the calculations would be much too complicated if the position of every single star were ...

Easternmost Roman aqueduct discovered in Armenia

Archaeologists from the University of Münster and the National Academy of Sciences of the Republic of Armenia have discovered remains of a Roman arched aqueduct during excavation work on the Hellenistic royal city of Artashat-Artaxata ...

Newly developed, bioinspired cell delivery vehicles

Nanocontainers can transport substances into cells where they can then take effect. This is the method used in, for example, the mRNA vaccines currently being employed against COVID-19 as well as certain cancer drugs. In ...
