Modified collagen could yield important medical applications

The synapse is a shotgun

... in silico modeling indicates that the synapse may behave more like a shotgun than a rifle when it comes to firing the neurotransmitters involved in neuronal communication. The textbook view of the synapse describes it as a place where rifle-like volleys of neurotransmitter are launched from one defined re...

Helping in a selfish world

...ory, natural selection has designed individuals to behave selfishishly; selfish individuals are likely to end up with more resources and therefore more offspring. But many species (including humans, some rock musicians, politicians, and everyday citizens among them) do co-operate. Traditionally, scientists...

Nanoscale method for investigating living systems

...s, and looks forward to understanding how the dots behave in vivo in excitable cells. The researchers will look next into properties that cause the artificial pores to open and close. ...

Simple explanation for complex pattern of feather development

...at signaling molecules in development can actually behave as envisioned by Turing 50 years ago. This work provides a key to some of these most basic questions of biology. The findings also indicate that more complex shafted feathers evolved from the simpler downy tufts by the addition of new players to the...

Single gene is genetic switch for fly sexual behavior

...at female flies with the male version of fruitless behave like males, directing at other females a sexual display nearly identical to their male counterparts. Female flies with the male version of the protein also make amorous advances toward male flies that express female pheromones. In these cases, "we h...

Scientists find a maturity gene in fly

...e over your kids, and they look very different and behave very different than they did previously. It happens more rapidly in insects, but they go through a transformation in very much the same way." DHR4 stands for Drosophila (the genus name for fruit flies) hormone receptor 4. The DHR4 gene carries inher...

MWG Biotech expands siMAX?siRNA portfolio with new scales, lengths and design tools

A 'dimmer switch' for genes

...rolled. Without the right information, cells can't behave properly, and may, as in the case of cancer, grow ... scientists to observe how the atoms of a molecule behave inside a magnetic field. The Graves team found that unstructured regions of the Ets-1 protein were a...

Researchers learn how blood vessel cells cope with their pressure-packed job

...the healthy bovine aorta endothelial cells did not behave that way in tests performed in the laboratory of Shu Chien, a coauthor of the PNAS paper and a professor of bioengineering and medicine and director of the Whitaker Institute of Biomedical Engineering at UCSD. When Chien and his collaborators stretch...

MicroRNA gene that regulates lifespan found by Yale scientists

Bacteria which sense the Earth's magnetic field

... such a chain structure allows the magnetosomes to behave together like a compass needle which orients the bacteria inside the relatively weak magnetic field of the Earth. But until now, scientists did not know how magnetosome chains are formed. The research group of Dr Dirk Schüler at the Max Planck Insti...

Past experience of pheromones induces dominant courtship behavior in fruit flies

...ith adult flies can influence how young flies will behave once they reach maturity. The work is reported by Jean-Francois Ferveur and colleagues at the Universite de Bourgogne, France, and the University of Manchester, United Kingdom. When an adult male fruit fly encounters a young male fly, he will activ...

Sperm stem cells closer to being like embryonic stem cells

...searchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body. Researchers at the Cecil H. and Ida Green Center for Reproductive Biology Sciences at UT Southwestern Medical Center devised methods to keep male rat germ-line...

'Computer-chemistry' yields new insight into a puzzle of cell division

...computers to calculate how components of molecules behave in small spaces -- in this case "how they wiggle," Rudolph said. By allowing both molecules to move -- as they would in the real world -- the researchers could evaluate whether match-ups that looked right when motionless were actually off the mark. ...

Common molecular 'signature' identified in solid tumors

...nd better interventions," says Croce. MiRNAs can behave like oncogenes, which promote tumor growth, or tumor suppressors, which keep potentially malignant cells in check. Croce points out that miRNA activity is tissue-sensitive, meaning some miRNAs may be overexpressed, or "turned on" in some of the cance...

Male rivalry increases when females at most fertile, say researchers

...l of Biological Sciences, also found that men only behave in this way if their female partner does not use oral contraception ?and is therefore more fertile. Images of male faces that were either high or low in dominant features, such as a strong jaw lines and thinner lips, were shown to male participants ...

New nano-canary in the nanotoxicology coalmine: The body itself

...st agree that these incredibly small materials can behave quite differently from conventional materials. Nonetheless, neighborhood stores feature products that promise benefits from these near-atomic level materials, from paints and cosmetics to toothpaste and sunscreens. But, could we be putting human he...

Amazon rainforest greens up in the dry season
