Scientists learn to predict protein-stabilizing ability of small molecules

...motion of the robotic instruments, the surgeon can perform extremely precise, intricate movements during the procedure. For example, if the surgeon’s hand moves five centimeters, he/she can scale the robotic hand to move only one centimeter. Robotic technology also offers a number of advantag...

Cells from amniotic fluid used to tissue-engineer a new trachea

...cells, that can make many of the tissues needed to perform repairs, Fauza says. While tracheal defects are rare, they're life-threatening: babies born with incomplete, malformed or missing tracheas cannot breathe and must immediately go on heart-lung bypass, which can cause neurologic and other complicatio...

Key brain regulatory gene shows evolution in humans

...r evidence of evolutionary selection. They plan to perform the same basic analyses, in which they compare sequence information between humans and non-human primates for signatures of evolutionary selection. ...

Recreating 'Flowers for Algernon' with a happy ending

...aster. But statin therapy enabled the NF1 mice to perform as well as their normal counterparts. "This is mind-blowing ?we think we have a real fundamental reason to be optimistic," explained Silva. "Here is a drug that affects a key learning and memory pathway, and completely rescues the most common gene...

The bioweapon is in the post

...South San Francisco. Even if they don't routinely perform sequence checks, some companies say that they do investigate their customers. But the scope of these checks varies widely. But email addresses are notoriously easy to fake. And even orders from legitimate institutions may not be what they seem. Alfre...

OHSU discovery sheds light into how stem cells become brain cells

...m cells suddenly start becoming glial cells, which perform a number of functions that include supporting the neurons. We wanted to find out what factors cause this switch in differentiation. We also wanted to determine if the process can be controlled and used as a possible therapy. What amazed us is that it...

How the neuron sprouts its branches

...entified at a dendritic branch point positioned to perform this fundamental neuronal function." Finally, the researchers disrupted the orientation, or "polarity," of the Golgi -- thus causing them to move into all the dendrites -- without disrupting their function. They found that disrupting the polarity c...

'Computer-chemistry' yields new insight into a puzzle of cell division

... from using sophisticated simulation techniques to perform "chemistry in the computer." In a paper published Nov. 24, 2005 online in the journal Biochemistry, members of the interdisciplinary collaboration described how they discovered the probable orientation required for a Cdc25B phosphatase enzyme to "do...

Argonne researchers confirm lead in Beethoven's illness

...e. "The APS is the best machine in the country to perform the research in this detail," said Ken Kemner, one of the Argonne researchers involved in the project. The group used microimaging to look at the distribution of lead in and on both the bone fragment and the hair to identify the presence of any surfa...

Understanding the oceans microbes is key to the Earth's future

...nduced change on the vital services these microbes perform for the planet remains largely unstudied, says a r... changes will have on the services marine microbes perform for the planet. Research on marine microbiology must continue or accelerate in order to solve these...

UCLA imaging study of children with autism finds broken mirror neuron system

...to the fMRI scans to assure researchers they could perform the tasks. Both groups performed equally well. Normal brain activity in areas of the brain involving sight and facial movements indicated that the children with autism remained on task during the fMRI scans. ...

Picking particles faster than one at a time

...ften turn to cryo-electron microscopy (cryo-EM) to perform single-particle reconstruction. Understanding structure is often the key to devising antibiotics and other therapies that can interfere with unwanted biological activity -- for example, the ability of infectious bacteria to synthesize proteins can ...

UCSD study finds anthrax toxins also harmful to fruit flies

...te the activities of several related proteins that perform overlapping functions in other diseases or biological processes. Such experimental tools could accelerate progress in various areas of biomedical research. Guichard first conceived this study in 2002, to apply her experience in molecular genetic st...

Hot-spring bacteria flip a metabolic switch

...mat becomes oxygen starved, making it difficult to perform respiration--an efficient energy-generating pathway that requires O2 to release the energy stored in sugars. Instead, the cells must rely on fermentation--a less efficient energy-generating pathway that can proceed without oxygen. Steunou and colleag...

3D ultrasound device poised to advance minimally invasive surgery

...s, the scanner could make such surgeries easier to perform and eventually more precise." Such surgeries also might be cheaper and less traumatic as they could be performed in less time and, in some cases, without the need of general anesthesia, he said. Duke developed the first 3D ultrasound scanner in 198...

Dr Leun Otten from UCL Psychology and the UCL Institute of Cognitive Neuroscience, who led the research project, said: "It sounds a bit ...

Ancient DNA helps UF researchers unearth potential hemophilia therapy

... Scientists have been trying to find a safe way to perform gene therapy in hemophilia patients for years, but problems with the viruses typically used to transport needed genes to their target destinations have stymied their success, Fletcher said. Researchers usually hide corrective genes inside viruses, w...
