Living view in animals shows how cells decide to make proteins

German researchers develop first non-invasive test to measure skin aging

...r wavelengths -- blue in the case of collagen, and green in the case of elastin. Since the upper layer of the skin, called the epidermis, is virtually transparent to infrared light, the infrared laser can reach the dermis with intense pulses of light without damaging the upper layers. By two different qua...

Transplanted photoreceptor precursor cells restore visual function in mice with retinal degeneration

...NRL gene regulatory element to tag the rods with a green fluorescent protein. This enabled Kellogg scientists to illuminate the rods, which begin as unspecified cells and gradually differentiate into cells dedicated to light reception. "One of our critical discoveries," says Swaroop, "is that there is a w...

Researchers identify neurons that assign value during learning

... light-sensitive (the protein is normally found in green algae). As a result of expressing channelrhodopsin-2, neurons could be activated simply by illuminating fruit fly larvae with blue light. This tool allowed the researchers to test whether such an activation of certain neurons can actually substitute ...

Studies find general mechanism of cellular aging

...ere going to calorically restrict yourself or take green tea or resveratrol every day for years in an effort to prevent aging, wouldn't you like some evidence that these not entirely benign things were having a beneficial effect? Now we have a biomarker that can directly test the effects of such things," h...

Researchers make nanosheets that mimic protein formation

...n appear colored under UV illumination from bright green to dark red depending on the nanoparticle size, are made from cadmium telluride crystals, a material used in solar cells. The sheets are about 2 microns in width, about 1/5 the thickness of a human hair. Scientists have long known how to coax nanop...

Poor athletic performance linked to vitamin deficiency

... B-vitamins are in whole and enriched grains, dark green vegetables, nuts, and many animal and dairy products. Manore suggests athletes and individuals with poor or restricted diets consider taking a multivitamin or mineral supplement....

Innovative movies show real-time immune-cell activity within tumors

"In the animals that received the vaccination, we saw two waves of activity after the T cells entered the tumor microenvironment," Weninger says. "Early on, the T cells didn't actively migrate through the ...

Molecular mechanism provides intra-cellular traffic signal

The molecular mechanism that underlies this coordination is reported by lead researcher Nava Segev, UIC professor of biological sciences, in the November issue of Nature Cell Biology. While the finding was made using yeast cells,...

Orkin and Wu then showed that these cells further differentiated into both myocardial cells and smooth-muscle cells. Next, using the same fluorescent "tags," Orkin and Wu i...

...on of anthocyanins in apples, and we found that in green apples this gene is not expressed as much as in red apples." In collaboration with apple breeders at the Department of Agriculture and Food in Western Australia (DAFWA), the scientists were able to show that fruit colour can be predicted even in se...

Parasitic plants sniff out hosts

Then, to narrow down the possible cues being used, they tested the seedlings' response to tomato plants slightly separated from the dodder seedlings, out of view so to speak, in a ...

Light-sensitive photoswitches could restore sight to those with macular degeneration

... that the channel turns the cell on when zapped by green light and turns the cell off when hit by ultraviolet light. The researchers demonstrated in 2004 that they could turn cultured nerve cells on and off with this optical switch. Since then, with UC Berkeley Professor of Vision Science and Optometry J...

'Cellular antennae' on algae give clues to how human cells receive signals

This alga allows researchers to manipulate genes and study the resulting effects on cilia in a way that would be impossible in animals such as mice. "Chlamy is one of the few model org...
