Verbal fluency tests are one of the most widely used tests in neuropsychology . The oral form of the test that is used today was first introduced by Benton and colleagues in the 1960’s and is mainly administered for evaluation of subjects sus pected of having neurological damage . Administration of fluency tests is fast, simple […]
Moss in Antarctica growing more quickly as temperatures rise Mosses are growing at a faster pace in Antarctica thanks to climate change. The moss is growing on the northern peninsula, making what little green there is on the continent greener as temperatures there rise. The Washington Post Trees moving away from eastern US in response […]
Since the discovery that graphene, the two dimensional carbon allotrope, can be isolated and incorporated into electronic devices intense research efforts have been triggered. Driving forces behind the experimental and theoretical studies of graphene are, e.g., the exceptional electronic properties, in particular the high electron mobilities, the long spin coherence lengths and the possibility to […]
Gary Becker presented a first economic approach to criminal behavior. In a very standard neoclassical framework he studied this apparently non-economic problem. In particular, Becker assumed rational criminals responding to variables such as the probability of being caught, the severity of the punishment and the labor-market opportunity cost. After this seminal work, a large empirical […]
There is a word everybody fears and that is because when you listen to it out loud, it could be too late. Even though we have likely coexisted with cancer since complex multicellular organisms evolved, to us human beings, it just seems the number of cases keeps growing every year. Sadly, that seems to be […]
Drug-resistant bacteria’s origins traced back 450M years The drug-resistant bacteria Enterococcus may have evolved from an ancient gut microbe that lived inside some of the first creatures that walked on land about 450 million years ago. Researchers examined the superbug’s genetic history as well as its ability to survive in harsh environments and found that […]
We know that incident light can provoke a strong optical response in metallic nanostructures due to the excitation of resonant plasmonic modes, i.e, the electrons in the metal become excited by the photons in the incident light and oscillate collectively. Plasmonic nanoparticles can significantly modify the optical properties of nearby organic molecules and thus present […]
Sexual differences in the human brain, both in structure and function, have a high scientific interest and a clear social impact. In the biological part because of the different susceptibility of both sexes to some developmental disorders such as autism — four times more frequent in males than in females — , and also to […]
In our current understanding of the nature there still are some big gaps of knowledge that reminds us of the long journey ahead in physics. Here I will be talking about one of the great mysteries of our time in science, and the great endeavor taken by some of the most skilled people I’ve ever […]
Mature parasite living in fish eyeball helps host become easy prey for birds The parasite Diplostomum pseudospathaceum grows inside fish eyeballs and, depending on its age, either protects its host or compels the fish to become easy prey to birds. When the parasite is young, it wants its fish host to stay alive so it […]
