WOODS HOLE, Mass.--Using a simple "mirror trick" and not-so-simple computational analysis, scientists affiliated with the Marine Biological Laboratory (MBL) have considerably improved the speed, efficiency, and resolution of a light-sheet microscope, with broad applications for enhanced imaging of live cells and embryos.
A discovery by an international team of researchers from Princeton University, the Georgia Institute of Technology and Humboldt University in Berlin points the way to more widespread use of an advanced technology generally known as organic electronics.
In the fight against brain damage caused by stroke, researchers have turned to an unlikely source of inspiration: hibernating ground squirrels.
MISSOULA - The origins of social inequality might lie in the remnants of ancient Eurasia's agricultural societies, according to an article recently published in the major science journal Nature.
The article, "Greater post-Neolithic wealth disparities in Eurasia than in North America and Mesopotamia," includes research from Anna Prentiss, a professor in the Department of Anthropology at the University of Montana.
A U of T Scarborough study finds that a unique ritual performed by male ring-tailed lemurs may come at a significant physical cost, but it could help their chances in securing a mate.
"Stink-flirting displays are done more often by dominant males," says Amber Walker-Bolton, lead author and instructor in U of T Scarborough's Department of Anthropology.
"This behaviour is also very costly because these males are met with higher levels of aggression than if they were to do other types of scent-marking, so there's definitely something unique about this type of behaviour."
It's no secret that human activities affect fish, particularly those that must migrate to reproduce. Years of building dams and polluting rivers in some regions have left fish such as salmon struggling to return to their home streams and give birth to the next generation.
Researchers at Washington University in St. Louis have traced the paths of three water channels in an ancient photosynthetic organism to provide the first comprehensive, experimental study of how that organism uses and regulates water to create energy.
Photosynthesis is the chemical conversion of sunlight into chemical energy via an electron transport chain essential to nearly all life on our planet. All plants operate by photosynthesis, as do algae and certain varieties of bacteria.
HOUSTON -- (Nov. 17, 2017) -- Nature whispers its stories in a faint molecular language, and Rice University scientist Laurence Yeung and colleagues can finally tell one of those stories this week, thanks to a one-of-a-kind instrument that allowed them to hear what the atmosphere is saying with rare nitrogen molecules.
The U.S. Department of Energy's (DOE) Argonne National Laboratory is collaborating with Hewlett Packard Enterprise (HPE) to provide system software expertise and a development ecosystem for a future high-performance computing (HPC) system based on 64-bit ARM processors.
Crosstalk and noise can become a major source of reliability problems of CNT based VLSI interconnects in the near future. Downscaling of component size in integrated circuits (ICs) to nanometer scale coupled with high density integration makes it challenging for researchers to maintain signal integrity in ICs. There are high chances of occurrence of crosstalk between adjacent wires. This crosstalk in turn, will increase the peak noise in the transient signals that pass through the interconnects.
