Biology – Sexual arousal can be detected in the breath

According to the study, sexual arousal can be detected by the composition of the air we breathe. Subjects exhaled less isoprene and carbon dioxide, but the concentration of breakdown products of certain neurotransmitters increased, according to a statement from the Max Planck Institute for Chemistry (MPIC) in Mainz. The researchers had subjects watch various film …

Skeleton from biology class buried by students – SWR3

For decades, students have learned about biology using female bones. The skeleton has now found its final resting place in North Rhine-Westphalia. But who was dead? Eleventh graders buried a skeleton from biology class at the Schleiden cemetery (NRW). He was carried in a blue coffin from the biology office of the Johannes-Sturmius Gymnasium to …

Synthetic Biology: Genetically Engineered Bacteria Store Carbon Dioxide

Carbon dioxide is a greenhouse gas, but it can also serve as an important raw material for the production of various chemical compounds. Some research groups are therefore working to identify CO2 intercept and use it judiciously before it enters the atmosphere. In “Nature Biotechnology,” a team of researchers now describes progress in which significant …
