Measurable effect of hypnosis on the brain
A study by American scientists proves, what hypnotists have claimed for years: they can indeed influence people's behaviour
by suggestion.
The team from Weill Medical College of Cornell University, New York examined the brain activity of
volunteers while doing the so-called Stroop test.
Half of the 16 volunteers had been hypnotised before and were given
instructions during this time.
They finished the task 10% faster afterwards and showed less activity in their anterior
cingulate cortex.
However, it is not proved yet, whether hypnosis is stricly necessary for this effect or whether
repeated suggestions would do the same.

Magnetic therapy against incontinence
A new therapy for children's incontinence was examined by a team from Yonsei University College of Medicine, in Seoul, Korea.
The children got magnetic treatment twice a week for 4 weeks and were grouped according to their symptoms.
Each group
showed a decrease in the frequency of incontinence and an increased average bladder capacity.
The team now calls for further
studies, to improve this therapy and to compare it to common treaments.

Nanoparticles in chemotherapy
Scientists from the University of Michigan developed a new way to transport methotrexat directly into cancer cells by loading
nanoparticles with methotrexat, folic acid and a fluorescent substance.
Since cancer cells need folic acid, they took up the
particles and were fought by the methotrexat.
In mice, cancer cells decreased after this treatment.

New pill against allergic reactions
People allergic to grass polls can hope for easier treatment soon.
For the therapy known as hypo sensitization,
allergens had to be injected regularly by the doctor until now.
A new pill, that contains allergens against grass and
can be taken at home was developed and is waiting for being approved for Europe by now.
Studies showed, that it reduces
the symptoms by more than 40%.

Long-living foam
Hydrophobic nanoparticles could be used to achieve more stable heads on beer.
Bernard Binks and Tommy Horozov
from the University of Hull worked with silicated nanoparticles, whose surfaces were modified with certain molecule groups.
Compared to other stabilisators such as natriumdodecylsulfate, those particles were more effective.
Due to the laws of
pureness in Germany, the invention will not be used for beer but might at least make bubble baths last longer.

Lipid rafts serve as gate for bacteria
Aggressive bacteria, that destroy human cells from inside can enter the cells via lipid rafts.
Scientists from the GBF
in Braunschweig and the University of Gießen had a closer look at Listeria monocytogenes, which is taken up with rotten food
and can cause colon infections.
A substance produced by
L. monocytogenes forces a number of small lipid rafts to form a
big "super raft", which influences the whole metabolism of the cell.
By this way, the bacterium can enter the cell easily.
