Artificial magnetic field produces exotic behavior in graphene sheets
Publicado em 29 novembro 2018
A simple sheet of graphene has noteworthy properties due to a quantum phenomenon in its electron structure named Dirac cones in honor of British theoretical physicist Paul Dirac (1902-1984), who was awarded the Nobel Prize for Physics in 1933.
The system becomes even more interesting if it comprises two superimposed graphene sheets, and one is very slightly turned in its own plane so that the holes in the two carbon lattices no longer completely coincide.
For specific angles of twist, the [...]

New ointment for treating brown recluse spider bites is tested on humans
Publicado em 28 novembro 2018The bite from a brown recluse spider (Loxosceles) can cause skin necrosis, renal failure, and even death. A new ointment is being tested in Brazil, however. Its effects have already been proven in tests conducted in cell cultures and animal models. Now the ointment will have its immunomodulatory action tested on humans in Phase III clinical trials, and it may be included in the treatment protocol for patients who develop lesions caused by the spider bite. The trial has started in [...]ver notícia -
Colored filter improves dyslexic children's reading speed
Publicado em 18 outubro 2018Reading, one of the most difficult activities for children with dyslexia, can be improved by the use of green filters. A study described in an article by Brazilian and French researchers reports increased reading speed for nine- and ten-year-old volunteers with dyslexia who used green filters. The filters had no effect on age-matched children without dyslexia. Colored filters for the treatment of learning disabilities were first patented in 1983. They were also designed for use by children [...]ver notícia
