One species, many genomes

...ingly irrelevant filler sequences. "That even in a minimal genome every tenth gene is dispensable, has been a great surprise," admits Weigel. Detailed analyses showed that genes for basic cellular functions such as protein production or gene regulation rarely suffer knockout hits. Genes that are important ...

Soils offer new hope as carbon sink

...s, has a pilot plant at Gosford which is producing minimal amounts for research purposes. "We are hoping the technology will take hold and pyrolysis plants will be built where there is a steady stream of green or other biomass waste providing clean energy that is carbon negative," Dr Van Zwieten said. "B...

Baumann Lab defines proteins that distinguish chromosome ends from DNA double-strand breaks

Percutaneous aortic valve replacement safe, successful in high-risk patients

...the lungs and severe shortness of breath with even minimal activity. With the CoreValve system, aortic valve replacement is performed by threading a special delivery catheter through the femoral artery in the groin and into the aorta in a direction opposite, or retrograde, to the normal flow of blood. Onc...

Study offers clues to 'Broken Heart Syndrome'

...men develop this syndrome after what appears to be minimal stress, while other women experience severely stressful events but don't develop Takotsubo cardiomyopathy," Dr. Regnante said. A surge of stress hormones likely plays a role, he said, but it is also possible that a blood clot temporarily blocks a maj...

Hybrid molecule causes cancer cells to self-destruct

Anthrax attack posed greater potential threat than thought

...e event, however, people in areas assumed to be at minimal risk of exposure showed immune responses suggesting they had been exposed. The researchers, Denise L. Doolan, PhD, MPH, Daniel A.

Research finds music training 'tunes' human auditory system

... starting before the age of 12. The other half had minimal (less than 2 years) or no musical training. All were native English speakers with no knowledge of Mandarin, a tone language. In tone languages, a single word can differ in meaning depending on pitch patterns called "tones." For example, the Manda...

ATR checkpoint-activating DNA structure

...leagues at Stanford University have determined the minimal DNA structure sufficient to activate the ATR-mediated DNA damage checkpoint. "We are very excited about these results," says Dr. Cimprich. "The ability to precisely define and manipulate the nature of the checkpoint activating structure in an exper...

Parasite infection may benefit MS patients

...ninfected group. Only two infected patients showed minimal Expanded Disability Status Score changes (EDSS is used to measure disability due to MS) that lasted less than three months, while the other 10 had no changes in EDSS scores. In the uninfected group, 11 patients showed an overall increase in EDSS. Sin...

Protein structure initiative launches new resources for the scientific community

...on. Researchers will be able to order clones for a minimal fee to cover processing, handling, and shipping. "Producing clones is an essential--and often time-consuming--step in the protein structure determination process," said PSI Director John Norvell, Ph.D. "By centralizing the availability of these m...

Fight weeds with plant pathogens

"Classical biological control using imported pathogens has an overall success rate of 57 percent and has been just as successful as the use of imported insects, with no instances of unexpected or undesirable effects," ...

New technology to speed up research into Huntington's disease

...ans of assessing cognition, in a way that requires minimal movement on the part of the mouse. The mouse makes its response by touching its nose to the touch-sensitive screen. This means that the HD mice can complete the task, despite motor problems. Other benefits are that it is less labour intensive, le...

Chen is currently completing medical school at Harvard and plans to continue to study molecules and evolution. "The cell, as an evolutionary...

Squid-inspired design could mean better handling of underwater vehicles

...res rapid deployment and high cruising speeds with minimal energy, their hydrodynamic design makes them more difficult to maneuver or dock at low speeds and in tight spaces, or to hover in precise locations. Underwater craft with boxier designs are easier to dock and maneuver, but speed is sacrificed in ...

Mass vaccination unnecessary in the event of a large bioterrorist US smallpox attack

...re of schools after a smallpox attack would have a minimal effect in preventing transmission of the disease, and that any delay in quarantining infected individuals would take a much greater toll on the community than failing to pre-vaccinate potential cases. To conduct the study, Longini and colleagues cr...

Cloning techniques produce FDA-approved antibiotic

...d van der Donk were able to determine not only the minimal set of genes required for fosfomycin biosynthesis, but also the function of some of these genes. "Our goal now is to produce fosfomycin in Escherichia coli so that we can use various protein and metabolic engineering tools to manipulate the fosfomy...
