New neurons take baby steps in the adult brain

...eir response to GABA) and to make them glow with a green protein to ease their identification in the adult brain. Ge measured the electrical output of the neurons to establish whether they had become connected to other neurons. "Getting new neurons to form connections in other parts of the brain may be h...

Protein behind autumn color splendor identified

... Most of the chlorophyll, which lends plants their green color, is bound to a protein called LHCII. Every individual protein is incredibly small (nearly a million times smaller than the human eye can perceive), but it is possible see them if there are many of them together. LHCII is probably the most comm...

Scientists closer to new cancer detection method

...itch that turns on the fluorescence." The probe's green fluorescent burst lasts little more than a billionth of a second - a nanosecond - but just long enough to separate it from surrounding signals, according to co-author Nicholas Turro, Ph.D., the William P. Schweitzer professor of chemistry at Columbia...

Prions rapidly 'remodel' good protein into bad, Brown study shows

... researchers tagged a non-prion form of Sup35 with green fluorescent protein in one group of cells and "mated" these cells with another group that contained the prion form. When the two forms came in contact in the same cell, the green-glowing, healthy protein changed pattern - a visual sign that it conver...

Emerald Spectre haunts Ontario's ash forests

... for Environmental Research. The small, metallic green beetle ?adults are about the length of a thumbnail ?was first detected following an unusual dieback of ash trees in southeastern Michigan and southwestern Ontario in the summer of 2002. A native of southeast Asia, the insect is capable of rapidly spr...

Picky female frogs drive evolution of new species in less than 8,000 years

...fic Ocean's Great Barrier Reef. The frog, which is green with reddish-brown splotches, is common around streams and grows to about 2 1/2 inches in length. Because of geographic isolation that began between 1 and 2 million years ago with the retreat of rainforest to higher elevations, two separate frog lin...

Discovery suggests why stem cells run through stop signs

...can regulate gene expression and give stem cells a green light to pass from the normal stop phase to the stage in which they begin replicating their DNA for later division. In their work, Carthew and Ruohola-Baker focused on fruit flies, which have approximately 80 types of microRNAs. They genetically mod...

It is an attractive target for biotechnology because it produces many different molecules important to agriculture and hum...

Scientists devise way to measure RNA synthesis on the fly in a live cell

...in called MS2. This MS2 protein also is fused to a green fluorescent protein that a laser can detect within a microscopically small volume. In the absence of RNA, the MS2 fused to the fluorescent protein moves rapidly. But when bound to RNA, the fused proteins move more slowly. From the speed of motion, "...
