Aspirin is typically prescribed for people at risk of having an ischemic stroke to prevent blood clots. Because aspirin may cause bleeding, it is typically avoided in people who have had a hemorrhagic stroke, also called intracerebral hemorrhage. A new study, however, finds that aspirin may not increase the risk of recurrent intracerebral hemorrhage. The study is published in the January 24, 2006 issue of Neurology, the scientific journal of the American Academy of Neurology (AAN).
Researchers followed 207 survivors of intracerebral hemorrhage at regular intervals to check whether they took an antiplatelet drug such as aspirin and if it increased their risk of another hemorrhage. In an intracerebral hemorrhage, a blood vessel bursts within the brain resulting in a pressure buildup that can lead to unconsciousness or death.
Out of 46 people who had aspirin treatment at some point during follow-up, seven had a recurrent intracerebral hemorrhage. Aspirin was prescribed to prevent ischemic heart disease in half of the group. No cases were reported where nonprescription aspirin was taken without a doctors recommendations. There were 32 others who also had a recurrent intracerebral hemorrhage but didnt take any aspirin.

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
