Watching the Nervous System Being Wired in Real Time

Thanks to a new imaging technology developed at Yale, the National Institutes of Health and Sloan-Kettering, scientists can now see for the first time the development of a living organism at the level of a single cell.

One of the developers, Yale cell biologist Daniel Colon-Ramos, illustrates the power of the new technology in this video that shows the migration of cells that will form the nervous system in a developing worm. (more…)

UCLA Scientists Engineer Blood Stem Cells to Fight Melanoma

Researchers from UCLA’s cancer and stem cell centers have demonstrated for the first time that blood stem cells can be engineered to create cancer-killing T-cells that seek out and attack a human melanoma. The researchers believe the approach could be useful in about 40 percent of Caucasians with this malignancy.

Done in mouse models, the study serves as the first proof-of-principle that blood stem cells, which make every type of cell found in the blood, can be genetically altered in a living organism to create an army of melanoma-fighting T-cells, said Jerome Zack, the study’s senior author and a scientist with UCLA’s Jonsson Comprehensive Cancer Center and the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA.

Physicists Set Strongest Limit on Mass of Dark Matter

Brown University physicists have set the strongest limit for the mass of dark matter, the mysterious particles believed to make up nearly a quarter of the universe. The researchers report in Physical Review Letters that dark matter must have a mass greater than 40 giga-electron volts. The distinction is important because it casts doubt on recent results from underground experiments that have reported detecting dark matter

PROVIDENCE, R.I. [Brown University] — If dark matter exists in the universe, scientists now have set the strongest limit to date on its mass. (more…)

A Smarter Way to Make Ultraviolet Light Beams

ANN ARBOR, Mich.— Existing coherent ultraviolet light sources are power hungry, bulky and expensive. University of Michigan researchers have found a better way to build compact ultraviolet sources with low power consumption that could improve information storage, microscopy and chemical analysis.

A paper on the research is newly published in Optics Express. The research was led by Mona Jarrahi and Tal Carmon, assistant professors in the Department of Electrical Engineering and Computer Science. The experiment was performed by Jeremy Moore and Matthew Tomes, both graduate students in the same department. (more…)
