Stroke study sheds light on left-right brain divide

...rules linking the colour of a symbol on a computer screen with a movement to the left or right. All the participants made mistakes during the task, but it was those with right-brain damage who most frequently failed to spot their errors and had difficulty keep track of the changing task rules. The group wit...

Penn researchers link cell's protein recycling systems

...aylor explains. “We can use fruit flies to rapidly screen through many genes to find the one we’re interested in. In the process of screening, our attention was drawn to HDAC6 because we already knew that it could bind to ubiquitin-tagged proteins and transport them within the cell. So we wondered, could H...

Fat screen delivers plant-derived chemical with antidiabetic effects

...sensitizers. By running a technologically advanced screen of more than 500 bioactive compounds, the researchers found that harmine has such a positive effect on fat. The fat cells under examination were manipulated such that they literally lit up when fat-boosting PPARã became active. Further study of ha...

It's never too late to get it back! Aging interrupted

...ople. The technique we have developed allows us to screen a relatively large number of drugs in months rather than years. The hope is that these drugs will be able to extend the lifespan of healthy animals, and possibly, after further testing, healthy humans? says Professor Spindler who will present his re...

The researchers employed signal processing and automated neural network analysis of event related potentials (ERPs) of the EEG signals, monitoring how the patient...

Using brain scans, researchers find evidence for a two-stage model of human perceptual learning

...series of cars presented at different parts of the screen and performed simple position judgments on the images, while their brain activity was being measured using an advanced functional Magnetic Resonance Imaging (fMRI) technique that made it possible to more directly probe neuronal tuning than in previou...

Scientists to track impact of Asian dust and pollution on clouds, weather, climate change

... said. Microarray technology enables scientists to screen thousands of genes at once to look for clusters of genes that may be involved in disease. Although there are many approaches to studying how different nerve cells in the brain react to stimuli from the environment, this mouse model is the first to...

Studies yield insight into the numerical brain

...ng fMRI to view consecutive numbers presented on a screen that represented either the same or different quantities. Crucially, the numbers were also presented either as two words (e.g., two or eight), two digits (e.g., 2 or 8), or a mixed notation (two and 8). They hypothesized "that if the assumption of ...

Largest genomic search finds genes that may contribute to autism

...le. As we identify these genes we will be able to screen young children for autism at an early age and begin interventions earlier, which can have a dramatic effect for some children," Dawson said. A second phase of the Autism Genome Project also was announced today to continue the effort to discover th...

Ultrasound upgrade produces images that work like 3-D movies

...ion of depth. Paired images seem to pop out of the screen when viewed with the special glasses. The researchers created an updated version of the image-viewing software found on clinical ultrasound scanners, making it possible to achieve a stereo display with no additional hardware. "To our knowledge,...

The FoxM1 gene is responsible for turning on genes needed for cell proliferati...

Interaction between lymph and liver cells may affect immune response

Tiny Tampa Bay fish key to evolution of immune system

Armed at first with nothing more than boots, a screen and a bucket, scientists studying a tiny primitive fish that makes up 70 percent of the biomass in Tampa Bay now say they have found the "missing link" marking the point in evolution that led to the development of the modern-day human immune system. ...
