Children's Hospital & Research Ctr. at Oakland's DNA library helps to map the sex chromosome

...tute are recognized world leaders for perfecting a technique that uses harmless bacteria to make many copies of long strands of fragile DNA. The DNA must be stabilized before it can be introduced into the bacterial cells. Once introduced into the cells, the bacteria are then tricked into reproducing and gener...

Dropping nano-anchor

... and gas properties--for anchor deposition." Their technique enables them "to deposit anchors on a wide variety of nanotube sample types, including those not easily incubated in solution," Fifield said. "It also enables us to control how much of a nanotube surface is coated with molecules and the thickness of ...

Two UCSF scientists receive top funding honor from medical institute

...ical-sleight-of-hand techniques, Shokat invented a technique that allows scientists for the first time to pinpoint where small molecules called phosphates attach to proteins in cells, allowing the cells to send signals and gives organisms a way to adapt to rapidly changing conditions. Diabetes, hypertension an...

Neutralizing a protein linked to tumor development

...docrine neoplasia (MEN) type 2 syndromes. Using a technique known as whole-cell SELEX (systematic evolution of ligands by exponential enrichment), a process in which large pools of oligonucleotides are enriched for molecules that can distinguish between a real and sham target, Libri and colleagues produced a ...

Harvard, Texas A&M scientists develop new laser

...Molecular Beam Epitaxy (MBE), the thin film growth technique pioneered by Bell Laboratories' Cho in the late 1960s that is now widely used in commercial products such as lasers for CD players. In MBE atoms are "spray painted" on a substrate to produce semiconductor films only a few atomic layers thick. "Perha...

Novel ultrafast laser detection of cancer cells also may improve understanding of stem cells

Trio of leukemias share a single mutation

...erative disease. The researchers used a sequencing technique developed in collaboration with co-authors William Sellers and Matthew Myerson of Dana-Farber. Specifically, they sequenced regions of tyrosine kinases that were likely to be mutated in the leukemias. Their sequencing analysis revealed that about 75 ...

Genetically modified natural killer immune cells attack, kill leukemia cells

...St. Jude team were the development of a laboratory technique for rapidly producing a large, pure population of ...lls from a small sample of blood; and developing a technique for genetically modifying NK cells so that they would become potent killers when they encountered le...

New imaging method gives early indication if brain cancer therapy is effective, U-M study shows

...the tumor's response. Researchers plan to test the technique with breast cancer and head and neck cancer. In addition to Ross, U-M study authors are Bradford Moffat, Ph.D., assistant professor of radiology; Thomas Chenevert, Ph.D., professor of radiology; Theodore Lawrence, M.D., Ph.D., Isadore Lampe Professo...

'Color-blind' method opens new doors in DNA sequencing

... green, yellow, and red. A common problem with the technique is that the color of light emitted by the dyes is similar. Even with complex computer programs to assist in deciphering the signals, this "cross-talk" between the dyes results in subtle variations that can cause nucleotides to be miscalled. The new m...

New technique finds molecules necessary for cancer metastasis

...the Chromophore-Assisted Laser Inactivation (CALI) technique he created 17 years ago to inactivate specific proteins in living cells at precise times and locations. The researchers are able to destroy a specific protein, sparing all other proteins attached to the cell as well as the cell itself, by targeting t...

Immune cells in the liver take a ride

...visible under a microscope. The researchers used a technique called intravital fluorescence microscope imaging to observe the behavior of the glowing cells in live mice. The study showed that the cells were undisturbed by the rapid blood flow, latching on to the vessels, then moving in random patterns in ...

Understanding natural killers could lead to new hepatitis treatments

... Littman. Working with Geissman, Cameron adapted a technique called intravital fluorescence microscopy that enabled them to observe in real time the behavior of the tagged cells in the livers of mice. "The startling discovery was that these NKT cells just move within the sinusoids intravascularly," said Littma...

Scientists' pied piper approach may have found Nemo faster

... speakers. A paper in Science journal suggests the technique could be used to restock depleted fishing grounds near reefs, or to populate newly established conservation areas. The study, which focuses on damselfish and cardinalfish in the Pacific Ocean, also warns that 'unnatural' noises created by shipping an...

Researchers unmask malaria parasite's cloaking mechanism

...s came into play in var gene activation. Using a technique called fluorescent in situ hybridization (FISH), which employs fluorescent-labeled probes specific for particular segments of DNA, the investigators gauged the position of var genes in on and off states and found that their hunch was correct. "There...
