St. Jude study solves mystery of mammalian ears

...absent. As sound waves race into the inner ear at hundreds of miles per hour, their energy—although dissipated by the cochlear fluid—generates waves in the fluid, somewhat like the tiny waves made by a pebble thrown into a pond. This energy causes the hair cell cilia in both mammals and non-mammals to swing ...

FDA sees nanotech challenges in every product category it regulates

Soils offer new hope as carbon sink

... while stable carbon like agrichar will last up to hundreds of years. "This is significant for farmer costs because one application of agrichar may be the equivalent of compost applications of the same weight every year for decades. "For the environment, it means soil carbon emissions can be reduced bec...

Modeling the restless brain

... human brain is structured -- how, for example the hundreds (the number is unknown) of regions in the human brain are connected. The computer model created by Sporns and Honey suggests that this very pattern of connectivity is crucial to generating and shaping brain activity in the resting and active brain. ...

Researchers examine carbon capture and storage to combat global warming

...irs, deep saline aquifers and unminable coal beds, hundreds to thousands of meters underground. The carbon dioxide is pumped down through wells, like those used to extract oil, and dissolves or disperses in its reservoir. Viable locations must have a caprock, or an impermeable layer above the reservoir ...

Undergraduate research shows leaderless honeybee organizing

...king intrusions into her “court” and vibrating her hundreds of times an hour. She responds by changing her behavior -- reducing her food intake, slowing egg laying and becoming more active. At this point, the workers begin to send a second signal that researchers call “worker piping” at a fevered pitch. Pipin...

Massive herds of animals found to still exist in Southern Sudan

...when a team traveled in a modified Cessna 182 just hundreds of feet above the ground for 70,000 miles (112,650 km) to create an unprecedented record of human impact on the land. A survey of Southern Sudan was part of the initial planning for the trip, but Fay was unable to complete his surveys due to politica...

Bacteria ferry nanoparticles into cells for early diagnosis, treatment

...n said. In the new approach, bacteria can carry hundreds of nanoparticles, each of which can in turn carry hundreds of drug molecules, depending on the size of the nanoparticles. The approach also could make it po...

454 sequencing identifies HIV drug resistance at early stage

...linded. “454 Sequencing can instantly generate hundreds of thousands of long clonal sequence reads that accurately enable the sensitive detection of rare mutations” explained Egholm Michael, Ph.D. vice president of research and development at 454 Life Sciences. “Ultra Deep Sequencing provides an essentia...

In nature, proteins sweep up nanoparticles

...f proteins and minerals that takes place as far as hundreds of microns away from the cell.” In other words, in addition to pumping nano-sized sulfide waste particles into the environment, bacteria also pump proteins into the environment. These proteins then sweep the sulfide nanoparticles out of solution i...

Antarctic icebergs -- Hotspots of ocean life

...the scientists began their shipboard sampling mere hundreds of feet from the icebergs and continued out to a distance of some five miles, where the icebergs’ influence was no longer detectable. “Phytoplankton around the icebergs was enriched with large diatom cells, known for their role in productive syst...

Puzzling plankton yield secrets to role in evolution/global photosynthesis

...nyuls-sur-mer, France. "This active absorption of hundreds of millions of tons of carbon per day is essential for maintaining the control of the planet’s climate by counteracting greenhouse effects due to human activities. Clearly, this storage capacity is affected by changes in the photosynthetic efficiency...

Amphibians in losing race with environmental change

...ugh they had the ability to evolve and survive for hundreds of millions of years - since before the time of the dinosaurs and through many climatic regimes - the massive, worldwide decline of amphibians can best be understood by their inability to keep pace with the current rate of global change, a new study...

Novel system developed to turn data into real-time, interactive 3-D images

...ows the physician to rapidly and efficiently study hundreds of images at once by turning the data into a three-dimensional (3-D) object that appears to float in midair." The technology will allow for manipulation of the volume-rendered object in real-time, giving physicians the ability to add and remove d...

Scientists: As rainfall changes, tropical plants may acclimate

...the entire tropics, but that would usually be over hundreds or thousands of kilometers," Schuur said. "I can visit all of these forest sites in a single day." The scientists analyzed nitrogen isotopes in the soil and leaf samples of four plant species at each site. They learned that drier soils contained m...

New technique will produce a better chromosome map

With so many crisp images to analyze, computer algorithms can accurately calculate the number, shape and location of the chromosome bands. "Two researchers might see the same image differently," said graduate r...

Fat screen delivers plant-derived chemical with antidiabetic effects

After screening hundreds of compounds for their effects on fat development, researchers have discovered that an ingredient found in some plants fights diabetes in mice without some of the side effects attributed to other antidiabetes drugs. The chemical they pinpointed, know...

DNA-damage test could aid drug development

...ew assay is a cell-culture system that could allow hundreds or thousands of tests to be performed from the bone marrow of a single mouse, and potentially from human bone marrow. Joe Shuga, the graduate student in chemical engineering who developed the assay, is in the unusual position of being a graduate ...
