Researchers find protein that silences genes

...ent tag and found that much of the HDA6, seen as a glowing red signal under the microscope, shows up in the nucleolus, which is precisely the site where ribosomal RNA genes are regulated and where nucleolar dominance occurs. "We found HDA6 at the scene of the crime, which was reassuring," Pikaard said. P...

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

...ocesses, collagen and elastin will then respond by glowing blue and green. Currently, dermatologists who want to check out the collagen network of a patient's dermis need to remove a sample of tissue and analyze it in the lab, under a microscope or by other methods. In particular, it is impossible to monit...

Fungal factories may save hemlock forests

Reaching into a box glowing with fluorescent light, Stacie Grassano pulls out a tube. "This is a great one," she says, holding the clear plastic up to her face. Inside, a tree branch is speckled with white fluff. "It's growing really well," she says, handing it to Scott Costa. ...

Immunization rates hit record high in poor countries

Reaching into a box glowing with fluorescent light, Stacie Grassano pulls out a tube. "This is a great one," she says, holding the clear plastic up to her face. Inside, a tree branch is speckled with white fluff. "It's growing really well," she says, handing it to Scott Costa. ...

Scientists use nanoparticle to discover disease-causing proteins

...a complex nanomolecule, called a dendrimer, with a glowing identification tag that was delivered to specific proteins in living venom cells from a rattlesnake. The scientists want to find a better way to ascertain the presence, concentration and function of proteins involved in disease processes. They also h...

Imaging techniques permit scientists to follow a day -- or four -- in the life of a cell

...fluorescently labeled, so scientists can track the glowing protein with a microscope and observe what it's doing and where it's going inside the cell. This microinjection technique is similar to those that are used to create cloned and transgenic organisms, and it can also be applied to more complex assays--...

Survival of the rarest: Fruit flies shed light on the evolution of behavior

...n a darkened room for several hours a day counting glowing larvae under a microscope. The researchers found that when the fruit fly larvae were competing for food, those that did best had a version of the foraging gene that was rarest in a particular population. For example, rovers did better when there w...
