Scientists perform 'tricky' operation

... in the genome sequencing of T. vaginalis and will create a visual blueprint of the parasite, allowing researchers to see where their genes fit in to the big picture." The results of the collaborative project have been published in the prestigious international journal...

Re-analysis of cigarettes confirms tobacco companies increased addictive nicotine 11 percent

...ontrol the level of nicotine delivered in order to create and sustain addiction" and further, that the "goal...that their products deliver sufficient nicotine to create and sustain addiction influences their selection and combination of design parameters." Cigarette...

Scientists unlock mystery of embryonic stem cell signaling pathway

...similar role in that system as well. “If we can create a totally chemically defined system for growing human embryonic stem cells without any risk of contamination, it would make life much easier for scientists than it is at the moment,?says Kahn. “And that’s our goal.?"Kahn's study provides us with stri...

Why is the heart heart-shaped?

...ternal forces (such as blood flow) is necessary to create the cell shapes that generate chamber curvatures. Disruption of this balance may underlie the aberrations observed in some types of heart disease. ...

Can engineered immune cells stop AIDS?

...-- the bone marrow cells that form blood cells ?to create B lymphocytes. The researchers want to reprogram these bone marrow cells by adding genes that will instruct the cells to produce rare antibodies such as B12, 4E10, 2G12 and 2F5. Wang says these antibodies are known to neutralize the virus. "In ...

Conceptualizing a cyborg

...eature of the proposed interface is the ability to create transplantable living nervous tissue already coupl... the mind could regain control," says Smith. To create the interface, the team used a newly developed process of stretch growth of nerve fibers called axon...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

...n conjunction with researchers at KU in Korea will create an integrated portal environment for the computational pipeline using results of Korea National e-Science Project by the Korean Ministry of Science and Technology (MOST); and CNIC will develop a transparent web service layer for data access. USM...

Leukemic cells find safe haven in bone marrow

...s showed that mesenchymal cells in the bone marrow create a protective niche for leukemic cells by releasing large amounts of asparagine, an amino acid that nearby leukemic cells must have to survive but do not make efficiently. This extra supply of asparagine helps leukemic cells survive treatment with asp...

Scientists unravel clue in cortisol production

...owering the activity of the immune system, helping create memories with short-term exposure, while impairing learning if there's too much for too long. Given the variety of its effects,understanding how cortisol is made is essential to producing medications that can alter its production. Scientists at the ...

Novel computed imaging technique uses blurry images to enhance view

...on can be computationally reconstructed to quickly create the desired image," Marks said. "We are now applying the technique to various microscopy methods used in biological imaging." In their paper, the researchers demonstrate the usefulness of computed image reconstruction on both phantom tissue and on ...

In presence of fragrant cleaning products, air purifiers that emit ozone can dirty the air

...ing supplies that gives them a lemon fragrance ?to create additional microscopic particles, scientists found. Certain ionic purifiers emit ozone as a byproduct of ionization used for charging airborne particles and electrostatically attracting them to metal electrodes. Ozonolysis purifiers emit ozone at hig...

Linheng Li Lab documents the development of cancer stem cells

...in our future work." "Findings from the Li Lab create opportunities to further characterize cancer stem cells and to obtain their molecular signature -- providing important insight into targeting these cells," said Robb Krumlauf, Ph.D., Scientific Director. "This is a fascinating new area of cancer rese...

Thinking with the spinal cord?

...stem must work as a whole in order to successfully create a single motion. The new research shows that even if we repeat a certain motion with high accuracy, the involved nerve cells never repeat their activity patterns. This particular observation reflects the organisation of the nerve cells of the cerebra...

Ultrathin films deliver DNA as possible gene therapy tool

...ells to make proteins. Lynn and his colleagues create the films one layer at a time using a dip-coating method, dunking first in one solution, then another. The individual layers are so thin it would take roughly 10,000 of them to equal the thickness of a single sheet of paper. As it turns out, maki...

Killing the messenger RNA -- But which one?

...e cellular machinery that uses that information to create proteins, the building blocks of the body. Several hundred species of microRNAs have been identified to date, and increasingly they are being seen as vitally important players in regulating the genome. Now, a new study led by researchers at The Wist...

...evelopment. In 2005 the technology was spun out to create Monica Healthcare Ltd. Led by both Dr Hayes-Gill and two ex PhD researchers from EEE, Dr Carl Barratt and Jean Francois Pieri, the company has gone on to develop the monitor even further. This highly sensitive device, which is able to detect 0.00...

New dopamine brain target discovered

George and O'Dowd and their team identified this complex by its unique reaction to dopamine or specific drug triggers. Strikingly, stimulating this target...

Nanoparticles can track cells deep within living organisms

... new blood vessels," Partlow says. "Because we can create a separate MRI signature for different cells with these various types of unique nanoparticles, we could use them to better understand each cell type's role." The nanoparticles are very compatible with living cells, according to the research findi...
