When the going gets tough, slime molds start synthesizing

...n the human diet as health-promoting components of green tea, red wine, and soybeans." Turns out, DIF-1 belongs to the same crowd. "While reading a review article on the diversity of polyketides in the journal Nature, we realized that the core chemical structure of DIF-1, an important developmental signa...

UT Southwestern researchers find gene mutation that leads to 'broken hearts'

... whose hearts glow by expressing a gene coding for green fluorescent protein specifically in the heart. "This fly with a glowing heart enables us to visualize the details of heart development with high resolution in living animals and to detect cardiac defects that have never been described before", said D...

'Micro-boxes' of water used to study single molecules

...hydrosomes") inside a tiny chamber on a slide. A green laser is then used to excite the molecules in individual droplets, and the light emissions over several seconds are analyzed to count the molecules and observe other phenomena. The researchers use two sets of optical tweezers to move droplets togethe...

DOE JGI finishes 100th microbial genome

...er aspects of the physiology and metabolism of the green sulfur bacteria." The search for microorganisms that can inform solutions to energy and environmental challenges can go to the extremes--the boiling hot pools in Yellowstone National Park, for instance--and lead to new biotechnology products. "DOE ...

Long-term changes in experience cause neurons to sprout new long-lasting connections

...ed mice that were genetically altered to produce a green fluorescent protein in specific neurons in the neocortex, which is a region of the brain that is known to adapt to new experiences. The researchers followed the growth of dendritic spines in the region of the neocortex that processes tactile informat...

Sandia work launched on space shuttle shows live cells influence growth of nanostructures

...us, the yeast can be modified to glow fluoresecent green when they contact a harmful chemical or biotoxin. Because such nanostructures are cheap, extremely light and small, and easy to make, they could conceivably be attached to insects and their emanations read remotely by beams from unmanned aircraft. ...

Toxic molecule may cause most common type of muscular dystrophy

...ats, each attached to DNA for a protein that glows green under a microscope. They also integrated an "on switch" for MMD in the mice, activated by giving them doxycycline, an antibiotic, in their drinking water. When mice began to produce many copies of RNA with CTG repeats, they developed the hallmarks...

Iron critical to ocean productivity, carbon uptake

...ve to wait to begin dividing and growing. But that green color wasn't an indication of health, it was an indication of stress from a lack of iron." The study is also important because it looked at the availability of iron throughout the tropical Pacific Ocean instead of small portions of it. Behrenfeld an...

Predicting successful outcomes in living-donor liver transplants

...ersity in Tsu City, Japan analyzed how indocyanine green (ICG), a non-toxic dye, was processed by the liver, assessed a non-invasive method of measuring its levels, and determined whether such a test would be a reliable indicator of outcome. The study involved 30 adult recipients who underwent LDLT betwee...

'Prosthetic' retinal cells let blind mice see light

...sed, called channelrhodopsin-2 (ChR2), is found in green algae. As reported in the April 6, 2006 issue of Neuron, Zhuo-Hua Pan of Wayne State University School of Medicine and colleagues found that the introduced protein rendered the retinal neurons sensitive to light. What's more, they found, the protein...

Biofuels can replace about 30 percent of fuel needs with significant research and policy effort

'Shuttling' protein possibly key to resilience of cancer cells

...otein fragments are reunited, causing them to glow green when illuminated with a light source. The fluorescence enabled the researchers to pinpoint the location of c-Jun-ATF2 heterodimers and discover the shuttling movements of ATF2. The ATF2 protein also has been found in the cytoplasm of diseased brain c...

Mice with glowing hearts shed light on how hearts develop

Biologists develop genome-wide map of miRNA-mRNA interactions

...sis system comparing the expression of a reporter, green fluorescent protein (GFP) carrying target 3' UTRs with controls, that did not carry the target 3'UTRs. The laboratory results confirmed the role of specific 3' UTRs in suppressing gene expression even more widely than predicted by the computational a...
