An international group of scientists, with the participation of Professor Marek Biesiada from the National Centre for Nuclear Research, proposes using quasars to determine the distance to celestial bodies. The method could be applied to objects, whose image reaches us after even 13 billion years.
In the same way that every person has a unique fingerprint, it is very likely that the set of compounds in exhaled air is unique as well. If the research of scientists from AGH-UST confirms this hypothesis, breath could become the next bioidentifier used, for example, to confirm identity.
Recently, researchers from the Institute of Physical Chemistry, Polish Academy of Sciences, in collaboration with TROPOS, Leipzig and NIC, Slovenia focused on revealing the fate of these volatile biogenic compounds in the atmosphere, investigating their lifetime and the processes they undergo.
