UF scientist: 'Brain' in a dish acts as autopilot, living computer

...e said. "(The brain is) getting its network to the point where it's a live computation device." To control the simulated aircraft, the neurons first receive information from the computer about flight conditions: whether the plane is flying straight and level or is tilted to the left or to the right. The n...

Newly discovered protein suggests novel tumorigenic pathway

...erine in the C-terminal segment. "From scientific point of view, it should be noted that PICT-1 is the first protein that interacts with the PTEN protein and regulates its phosphorylation," said Maehama. The researchers hypothesize that PICT-1 may affect phosphorylation by activating a kinase or inhibitin...

Early life stress harms mental function and immune system in later years

...aptability to new stimuli. Together, these studies point to exciting new approaches for potentially lessening or preventing these long-term changes that can lead to disease or psychopathologies. Stresses such as neglect and abuse during infancy may result in memory loss and impaired cognitive abilities ...

Calorie restriction leads to some brain benefits but not others in mice

In addition to validating these findings in larger groups of mice, the team also is exploring the possibility that adjusting other dietary factors may enhance and add to the calor...

Bug's-eye-view of urinary tract reveals E.coli infection genes

The study was designed to compare gene expression levels for the CFT073 strain of E. coli as the bacteria grew in three different environments. The first was a container of nutrient-rich Luria broth. The second was a container of pooled ur...

Insects implicated in the evolution of new human infectious diseases

...n of Nature Reviews: Microbiology, the researchers point to the large reservoir of diseases in invertebrates, such as fleas and nematode worms, which are currently harmless to humans, but which could evolve quickly into a range of new diseases. As part of their research, Dr Nick Waterfield and Professor Ri...

Psychologist finds instance where 'two wrongs do make a right'

.... However, when observers were asked to physically point toward the spot, they did so with very little error. "Perception is prone to the illusion, while action seems immune," explains Dassonville, echoing the commonly accepted axiom that separate visual systems drive perception and action. However, the UO...

Genetic influences on taste perception of alcohol may influence alcohol intake

Whether the genetic differences that underlie sensitivity to bitter tastes contribute to early experimentation with alcohol is an imp...

Sex versus survival: A tradeoff at geographical range limits

"This is significant because almost all of the designated species at risk in Canada consist of populations at their north...

UCSD discovery opens new avenues for design of anti-tumor medications

It is still a moot point whether, after hundreds of thousands of years, gas was still escaping from the volcanic subsoil which formed the extinct volcanic crater lake of Messel.

"Although 15,589 species are known to be threatened with extinction, this greatly underestimates the true number, as only a fraction of known species have been assessed. There is still much to be discovered about key species-rich habi...
