Scientists from IBM Research have produced six Nobel Laureates, 10 U. (IBM Research) IBM Researchers Store Data on World's Smallest Magnet -- a Single Atom Christopher Lutz, nanoscience researcher at IBM Research - Almaden in San Jose, Calif.
- : IBM (NYSE: IBM) today announced it has created the world’s smallest magnet using a single atom – and stored one bit of data on it.It is therefore advantageous to avoid sick individuals. dating for unge Kolding Scientists including Clémence Poirotte from the German Primate Center investigated how mandrills, an Old World monkey species inhabiting equatorial rainforests of Gabon, recognize conspecifics infected with intestinal parasites and avoid an infection.Humans - like most non-human primates - are social beings and profit in many respects from the benefits of a community.However, their closeness to conspecifics is an opportunity for pathogens and parasites to infect new hosts.
Social grooming is of enormous importance for the group members since it minimizes conflicts and increases the well-being of both grooming partners.However, the resulting physical proximity also increases the risk of transmission of pathogens.The monkeys are able to smell an infected group member and consequently groom them less than healthy individuals.This component of the "behavioral immune system" of mandrills plays a crucial role in the co-evolution of host and parasite (Science Advances 2017).(Photo credit: IBM Research - Almaden) By starting at the smallest unit of common matter, the atom, scientists demonstrated the reading and writing of a bit of information to the atom by using electrical current.

They showed that two magnetic atoms could be written and read independently even when they were separated by just one nanometer – a distance that is only a millionth the width of a pin head.
“Magnetic bits lie at the heart of hard-disk drives, tape and next-generation magnetic memory,” said Christopher Lutz, lead nanoscience researcher at IBM Research – Almaden in San Jose, California.
“We conducted this research to understand what happens when you shrink technology down to the most fundamental extreme -- the atomic scale.” Dr.
The custom microscope operates in extreme vacuum conditions to eliminate interference by air molecules and other contamination.
The microscope also uses liquid helium for cooling that allows the atoms to retain their magnetic orientations long enough to be written and read reliably. For more information about IBM Research, visit com/research.
