Good times ahead for dinosaur hunters, according to U of Penn scientist's dinosaur census

...f discoverable dinosaurs upward by 50%, offering a brighter outlook about the number of dinosaurs waiting to be found. His findings also add evidence that dinosaur populations were stable, and not on the decline, in the time shortly before their extinction 65 million years ago. Dodson proposes that 1,850 ge...

Chemical tests of cell growth enter third dimension

...um. The 3D glob of cells in the middle well glows brighter than a 2D film, due to a specific optical effect, Yang said. The surrounding empty cells provide a darker background that lets the fluorescence signal be measured even more easily. "You can use this as a device to monitor a drug's effect, whether y...

Paying attention sets off symphony of cell synchronization

...om the participants showed more brain activity for brighter stimuli, as expected, but responses also varied depending on attention. The patterns of these brain waves allowed the investigators to obtain a thorough description of how attention altered neural function. "For dynamic stimuli at the focus of atte...

A rice future for Asia

...y, be convinced of how rice research can provide a brighter future for rice in the region. "We want them to understand that rice research is not some sleepy little scientific backwater, but is, in fact, right on the cutting edge of international scientific activity," Dr. Zeigler said. "The recent sequencing ...

Wasps queue for top job

...ving the nest is dangerous. We have found that the brighter the individual wasp's future, the less likely it is to take risks by leaving the safety of its nest to forage for food." The defining feature of eusocial animals - including insects like bees, ants and wasps, and vertebrates like meerkats and the n...

New light microscope sharpens scientists' focus

...s that must be collected, and making the molecules brighter would reduce the time needed to take each image. Either would help to speed the PALM process ?a high priority for the Hess and Betzig as they continue to refine the technique. The two inventors are eager to continue developing their technique into...

Nanotechnology may find disease before it starts

... we're interested in." The ultrasound images grew brighter over the 90-minute period. The researchers compared these images to those from a group of control mice injected with a saline solution. There was no change in ultrasound image brightness in the control mice after that injection. While this research ...

New nanosensor uses quantum dots to detect DNA

...ut 60 DNA sequences, making the combined glow even brighter and easier to see. To test the new technique, Wang's team obtained DNA samples from patients with ovarian cancer and detected DNA sequences containing a critical mutation. "This method may help us identify people at risk of developing cancer, so th...

Purdue's gold nanorods brighten future for medical imaging

... mice, the nanorods yielded images nearly 60 times brighter than conventional fluorescent dyes, including rhod... fluorescence," which provides higher contrast and brighter images than conventional fluorescent imaging methods. Photons are the individual particles that mak...

Overbearing colored light may reveal a second mechanism by which birds interpret magnetic signals

.... However, the researchers also found that under brighter turquoise light, corresponding to light levels found 20 min after sunset, the birds still orient by the magnetic field, but they no longer show the seasonal change between spring and autumn and instead head north in both seasons. This behavior did no...

Researchers seek to discover what really happens when a virus enters the body

...rom the microscope's uneven illumination, which is brighter in the center and dissipates nearer the edges of the dish for each sub-image. To compensate for this artifact or noise, Bell's lab has developed "a method to remove the grid created by assembling the montage of sub-images. Our method ?based on a mo...

Color-blind method opens new doors in DNA sequencing

...r the measuring of fluorescence, because PME gives brighter signals and collects more of that signal by eliminating the need for a prism to separate the light into colors." Metzker is also seeking to develop a chip-based imager than could be used in his overall project on sequencing-by-synthesis (SBS), which...
