Mutating the entire genome

...o know the function of the genetic blueprint is by removing part of the DNA and seeing what goes wrong. We have found a way to do this job on a large scale that is simple and practical.” Capecchi says: “We developed a method for deleting any piece of DNA from the mouse genetic blueprint very efficiently.”...

Helping chlorine-eating bacteria clean up toxic waste

...(PCE) and trichloroethylene (TCE). They do this by removing chlorine atoms from molecules and leaving less-toxic compounds behind. But D. ethenogenes strains work well at some sites and not so well at others, and nobody knows for sure why. In fact, very little is understood about how these organisms live a...

Scientists close in on missing carbon sink

...n sink, concludes that intact tropical forests are removing an unexpectedly high proportion of carbon dioxide from the atmosphere, partially offsetting carbon entering the air through industrial emissions and deforestation. The Science article, "Weak northern and strong tropical land carbon uptake from verti...

Antarctic icebergs -- Hotspots of ocean life

... dynamics in complex ways, this additional role of removing carbon from the atmosphere may have implications for global climate models that need to be further studied,” added Smith. To understand the icebergs’ complex impacts, the multidisciplinary team of researchers carried out the most comprehensive st...

Technique monitors thousands of molecules simultaneously

...ged to a fluorescent label. The washing step risks removing a bound receptor if it does not bind the molecular key strongly enough. But, with an electrochemically addressable computer chip, provided in great abundance by one of his sponsor's, CombiMatrix in Seattle, Moeller saw a way of probing the binding of...

Iowa State scientists demonstrate first use of nanotechnology to enter plant cells

...The biologists attempted to mimic that process by removing the wall of the plant cell (called making protoplasts), forcing it to behave like an animal cell and swallow the nanoparticle. It didn’t work. They decided instead to modify the surface of the particle with a chemical coating. "The team found a...

But despite the recommendations of two national advisory committees in 10 years that voted in favor of all patients in the United States receiving leukoreduced blood, ("universal leukoreduction"), ...

Better assessment of transfusions could save blood

...blished in Seminars in Dialysis. Phlebotomy, the removing of blood from the body, has been seen as a major factor contributing to anemia, but recent research shows that it may not be the primary cause. “There is now ample evidence suggesting that the anemia observed in the critically ill is an underproducti...

Woven scaffolds could improve cartilage repair

...engineering approach to such joint repair involves removing cartilage cells from patients and then "growing" them in a laboratory to form new cartilage. However, it can take several months to grow a piece of cartilage large enough to be implanted back into the patient. Additionally, this laboratory-grown cart...

UCSD researchers discover variants of natural tumor suppressor

...HLPP1 could be used to treat diabetes; in essence, removing the 'brake' and allowing Akt2 to be more functional and allow better insulin regulation. PHLPP2, on the other hand, controls the driver on Akt1, the path involved with cell survival. Therapies directed at releasing the brake on this driver would al...

Nanotechnology meets biology and DNA finds its groove

...ns, already know how to take DNA and stiffen it by removing salts from its chemical makeup. But confining the molecule and presenting it for analysis is laborious, engaging armies of lab techs worldwide to prepare DNA samples for their moment in the lab. "To get DNA molecules to do this on surfaces is real...

After removing the vitreous, which is the gelatinous fluid inside the back part of the eyeball, Narfstrom creates a small blister in the retina and a small opening, large enough for the microchip, which is just two millimeters in diameter and 23 micrometers (one...

QUT scientists on the way to sifting out a cure for HIV

...d preliminary research had proved it successful in removing viruses from water. Nanofiltration is the filtration of minute particles using a filter with extremely small pores. "If we can remove compounds from liquids and viruses from water, then there may also be potential to remove HIV from blood," Dr ...

Protein found to shield pancreatic cancer cells from self-destruction

...ncer cells from being forced to devour themselves, removing one of the body's natural defenses against out-of-control cell growth, researchers at The University of Texas M. D. Anderson Cancer Center report in the March issue of Molecular Cancer Research. The protein tissue transglutaminase, known by the abbr...

Are scientists making progress in being able to regenerate bone tissue?

...e are major problems with such grafts—for example, removing bone from a different part of the body can lead to post-operative pain, infection, and abnormal sensations at the removal site. An alternative is to use bone given by a donor—but such bone grafts from donors are less successful and there is a risk o...

Experimental vaccine given during pregnancy reduces stillbirths from common virus
