US control strategies may make flu epidemics worse, UCLA study shows

... program. The model Blower's team developed is inspired by game theory, used in economics to predict how non-communicating, selfish individuals reach a collective behavior with respect to a common dilemma by adapting to what they think are other people's decisions. The group modeled each individual's stra...

...endently of neuroscience. Our work is biologically inspired computer science." "We developed a model of the visual system that was meant to be useful for neuroscientists in designing and interpreting experiments, but that also could be used for computer science," said Thomas Serre, a former PhD student an...

Darwin's famous finches and Venter's marine microbes

...ter transformed into a marine research vessel, was inspired in part by the journeys of the HMS Beagle and the HMS Challenger in the nineteenth century. But unlike those pioneering expeditions, the Sorcerer II team led by J. Craig Venter and a globe-spanning network of collaborators are after tiny microbes, cl...

Canadian study shows bilingualism has protective effect in delaying onset of dementia by four years

...l in both children and older adults. Those results inspired Bialystok and her research team to ask, "So what does this mean for the onset of dementia?" In this present study, researchers set out to answer that question by examining the diagnostic records of 184 patients who came to Baycrest's Sam and Ida Ro...

New clues to how sex evolves

...gh gene duplication and subsequent selection. This inspired Dernburg and Phillips to look at similar genes in the related species C. remanei and C. briggsae. Like C. elegans, C. remanei has a total of four such genes, while C. briggsae has five. All code for zinc-finger proteins, all of which are distinct fro...

Squid-inspired design could mean better handling of underwater vehicles

...recision. In addition, the technology - seemingly inspired by the plots of two classic sci-fi films - may soon allow doctors to guide tiny capsules with jet thrusters through the human digestive tract, enabling them to diagnose disease and dispense medications. Kamran Mohseni, an assistant professor of ae...

Experimental cancer drugs counter muscle deterioration seen in muscular dystrophy

... deacetylase inhibitors on muscle regeneration was inspired by his previous studies, which started 10 years ago, in collaboration with Dr. Vittorio Sartorelli at NIH, on the biochemical and molecular mechanism regulating the expression of genes that coordinate muscle regeneration. These studies led to the ide...

Like a snail through the intestinal canal

...U Delft, an alternative method has been developed, inspired by the way in which snails move. On September 18, researcher Dimitra Dodou received her PhD degree from TU Delft based on this research subject. The intestines are an extremely difficult area to navigate through with a medical device. Yet, many peo...

With record resolution and sensitivity, tool images how life organizes in a cell membrane

...lier work on phase-separated membranes on surfaces inspired the system used in the work, and scientists Peter Weber and Ian Hutcheon, both experts in imaging mass spectrometry at the Lawrence Livermore National Laboratory (LLNL), who provided access to the state-of-the-art machine used in the experiments. Th...

Snakes' virtual glasses, leopard spots and all-optical transistors

...v74/e011914 Leopard's spots and Zebra's stripes inspired the ancient myths famously retold in Kipling's "Just So Stories." They also led legendary mathematician Alan Turing to suggest that some patterns in nature are due to various chemicals, or morphogens, diffusing across surfaces and forming shapes wher...

New light microscope sharpens scientists' focus

... a tool developed in a biology lab that ultimately inspired the two physicists plan to build a better microscope. "In the world of biology there is a new generation of fluorescent proteins that you can switch on at will with a little bit of violet light," Hess explained. He and Betzig learned of these molecul...

Stanford snake venom study shows that certain cells may eliminate poison

...the venoms' most toxic components. The study was inspired by a 2004 paper in Nature, by Galli and a team of researchers including Metz, showing that mast cells reduced the mortality rate of mice suffering from bacterial peritonitis, a severe bacterial infection in the abdominal cavity that can also be fatal...

Evolution mystery: Spider venom and bacteria share same toxin

...ious illnesses in farm animals. "Our research was inspired by the fact that we have a group of spiders with a unique toxin, and that toxin also happens to exist outside the animal kingdom in this particular bacterium," she added. "A pattern like this raises the possibility of lateral gene transfer as a expla...

Frog’s ear canal may provide insights for understanding human hearing loss

...rstand the hearing process in humans, and the more inspired we can be in developing new treatments for hearing loss," said James F. Battey, director of the NIDCD. Ultrasounds are high-pitched sounds more than 20 kilohertz (kHz) in frequency, exceeding the upper limit of sounds detectable by humans, and far h...

Engineers discover why toucan beaks are models of lightweight strength

... horn. Just as the hook-shaped barbs on cockleburs inspired the development of Velcro, Meyers said the avian bio-composite could inspire the design of ultra-light aircraft and vehicle components with synthetic foams made with metals and polymers. "The big surprise was our finding that the beak's sandwich st...

Carnegie Mellon U. transforms DNA microarrays with standard Internet communications tool

...cks errors made during email transmissions has now inspired a revolutionary method to transform DNA microarray analysis, a common technology used to understand gene activation. The new method, which blends experiment and computation, strengthens DNA microarray analysis, according to its Carnegie Mellon Univer...

The nude mouse tale: Omega-3 fats save the life of a terminal cancer patient
