Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals

...eed to sacrifice animals and perform laborious and costly analysis. To trigger living cells into producing their own contrast agent, Ahrens gave them a gene that produces a form of ferritin, a protein that normally stores iron in a non-toxic form. This metalloprotein acts like a nano-magnet and a potent MR...

Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin

... of cancer tissue, as such technology will be less costly and more accessible than MRI-based methods and free of the harmful side effects associated with radioactivity. In this imaging system, the flourophores can also be tuned to respond to different wavelengths of near-infrared light. This sets the stage ...

Researchers devise way to mass-produce embryonic stem cells

...al laboratory methods used to grow these cells are costly and don't produce cells fast enough to respond to increasing demands for human embryonic stem cells, said Shang-Tian Yang, a professor of chemical and biomolecular engineering at Ohio State University. Federal rules forbid the federal funding of res...

New Drugs For Bad Bugs: UF Approach Could Bolster Antibiotic Arsenal

At the molecular level, the predator is the prey

... sort of change in the sodium channel would be too costly to the snakes," said Utah State University biologist Shana Geffeney, who conducted the gene expression experiments. "What will be interesting in the future is to understand if there is a balance between the costs of the changes in the channel pore st...

Tsunami-damaged coral reefs should be left to recover naturally, say scientists

...ents should be very careful not to commit funds to costly repair programmes that may have little long-term effect. About 20 per cent of the coral reefs in places such as Thailand and Sri Lanka were badly affected by the tsunami that happened in December last year. The damage was mainly caused by the backwa...

It's electric: Cows show promise as powerplants

.... But converting methane into electricity requires costly equipment : one California farmer reportedly spent $280,000 to convert his operation to a methane digester system. "Methane still needs to undergo combustion, which creates issues with energy efficiency," said Hamid Rismani-Yazdi, the study's lead a...

We simply reasoned that it might be possible to improve the benefits of interferon by enhancing the way it produces its beneficial effects. We therefore improved a molecule, known as Stat1, that is re...

Circumventing these technical limitations, Ueli Schibler and colleagues report in the open-access journal PLoS Biology a new method to measure circadian cycles in mammalian cells cultured from tissues other than the suprachia...

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

...em should also be relatively inexpensive. The most costly ingredient is the quantum dots: A small bottle that contains enough of the material for about 200 tests costs $300. As a result, this could be one of the earliest medical applications of nanotechnology, Wright and Crowe say. The researchers' next s...

A vaccine to kill tapeworm
