Study shows lizard moms dress their children for success

...combination of laboratory and field experiments to tease apart a complex set of interactions involving hormones, genetics, social interactions, behavioral strategies, and predators. Previous studies by Sinervo and his collaborators have described three different behavioral strategies that correlate with th...

An ancient bathtub ring of mammoth fossils

...Western Washington University. "We’re trying to tease out as much information as we can about each and every mammoth find in the mid-Columbia basin, so that we can better understand the impacts that Ice Age floods may have had on the mammoths and other creatures, and in turn learn more about the history...

Anthrax paralyzes immune cells with lethal toxin, UF research shows

...n. Southwick's team used an unusual approach to tease out the anthrax toxin's effects on cell migration: They allowed the immune cells to be hijacked by another bacterium, Listeria monocytogenes. Listeria is often used as a tool to study actin because it commandeers human cells and induces them to form ...

New technique will produce a better chromosome map

...ruct the first accurate map of the chromosomes and tease out the secrets hidden in their stripes. Their ...ific DNA sequences. These landmarks will help them tease out the relationship of the sequence to the physical structure. The new approach will allow scien...

Executable biology -- Computer science sheds light on animal development

...oup of researchers in Switzerland has been able to tease out what laboratory experiments have not ?how and when the crucial cross-talk between cellular signaling pathways takes place in order to determine the fates of individual cells. The novel in silico model is described in a paper appearing May 18, 200...

Deconstructing brain wiring, one neuron at a time

...onfigured. To do this, they need a tracer that can tease apart the chain of directly connecting neurons, identifying them one by one. Viruses that naturally spread between neurons have previously been used to outline the flow of nerve cell communication, but they have two drawbacks. First, once inside t...

Enhancing activity of marijuana-like chemicals in brain helps treat

...uivocal way to identify the cells allowed them to tease apart the functions of the different cell types. Malenka's lab has long studied how the communication between different neurons is modified by experience and disease. In their examination of two types of mouse striatum cells, Kreitzer and Malen...

Study of planarians offers insight into germ cell development

...racteristics with mammals that may help scientists tease out the mechanisms by which germ cells are formed ... also uses inductive signaling is going to help us tease apart the more conserved mechanisms (of germ cell development and maintenance)," Newmark said. "We h...

Anti-fungal drug stops blood vessel growth

...angiogenesis.? While the researchers still must tease out exactly how itraconazole works to stop vessel growth, and test it in animals with cancer, they have high hopes for its use. “Itraconazole can be taken orally for fungal infection, and therefore oral delivery may work for angiogenesis as well,?Liu...

Global changes alter the timing of plant growth, scientists say

...replicated eight times to allow the researchers to tease apart the separate influences of factors and test the statistical significance of their results. Data reported in this study were obtained from 1999 through 2003. "Under today's conditions, grasses flower early in the growing season and wildflowers...

Where we change our mind

...on, they describe experiments that enabled them to tease apart how different regions of the cerebral cortex process uncertain information and integrate it into decision making. In particular, their aim was to analyze subjects' navigation through a virtual maze, to explore how different cortical regions fu...

Brain's 'gambling circuitry' identified

...ructures in the brain. Importantly, their findings tease apart the gambling function of these brain structures from their functions in learning, motivation, and assessment of the salience of a stimulus. In their research article published in the August 3, 2006, issue of Neuron, published by Cell Press, t...

Plants tell caterpillars when it's safe to forage

...f photoperiod from that of host plant volatiles to tease out their relative contributions to caterpillar behavior. First, they tested the effects of light. If larvae are diurnal, they should hide in "shelters" fashioned out of filter paper attached to the plastic cups they were kept in. When larvae were fe...

Invasive species alter habitat to their benefit

...d Deborah Goldberg, however, came up with a way to tease out the cause of environmental changes in northern Michigan wetlands where invasive cattails have taken hold. The cattails, they found, alter the environment in ways that hinder native species but benefit the invaders. Farrer and Goldberg will presen...

New approach to vaccine development provides potent, long-lasting immunity

...steps. First, the computer programs were able to tease out that the brain picked up the control task quickly, but actually forgot the task quickly as well. But, at the same time, the brain also was learning the same task more slowly, and that was responsible for the subjects' being able to "remember" the...

Robotic joystick reveals how brain controls movement
