Pleasing plant shapes explained by new computer model

...aboratory experiments. It also promises to lead to accurate models of how other organisms, including animals, develop from primordial stem cells. "This was a great example of the synergy you can have between biology and computer science and how the tools of one discipline can be used to answer questions in a...

Chemical warfare agent detection technology used to treat lung disease

...such that we will not only be able to provide more accurate diagnosis, but we will also be able to tailor treatments to the individual. For instance, if a patient is taking steroids for asthma, we would be able determine whether they were being given the right amount of steroids from the molecules in their br...

High-tech tags on marine animals yield valuable data for biologists and oceanographers

... said. "It's like predicting the weather. To get accurate predictions, the weather models have to be constantly updated with new data from weather stations all over the country," he said. The researchers are also gaining new insights into the lives of California sea lions, said Michael Weise, a graduate st...

U of MN researchers identify ataxia gene

...cific type of ataxia provides patients with a more accurate picture of what the future holds. Ranum added: "Finding the SCA5 mutation in Lincoln's family makes it possible to test Lincoln's DNA ?if it becomes available ?to unequivocally determine if he carried the mutation and had or would have developed the...

Study suggests that publicly available genome data may contain small but significant errors

...o the difficulties of establishing a canonical and accurate sequence or physical map, and suggests ways that the two types of data can be combined to render increased confidence levels of the assembly. This physical mapping technology is simple to implement and is relatively inexpensive. It is likely to h...

Common enzyme is a key player in DNA repair

...B DNA polymerase is specialized for proficient and accurate replication of a particular kind of damaged DNA, reports Graham Walker, an HHMI professor at the Massachusetts Institute of Technology, and his colleagues in the January 12, 2006, issue of the journal Nature. HHMI professors are leading research scie...

Does father know best?

...hropology sheds new light a contentious issue: How accurate are men's suspicions of whether or not they are a child's biological father? Some studies have suggested that up to 10 percent of fathers are not the biological parents of their alleged child, but little is known about how this differs across culture...

Georgia Tech accelerates drug discovery with new IBM supercomputing cluster

... power and system resources they need to make more accurate decisions in research and raise the profile of the Institute among the nation's most elite research facilities." "Only the most technologically savvy universities are able to compete in the field of drug discovery and bioinformatics," said Mike Cass...

FSU biologist says new dinosaur is oldest cousin of Tyrannosaurus rex

...e reached its full size by then, thus providing an accurate model for scientists. The bones of the smaller specimen had only six closely spaced rings and no widely spaced ones, indicating that it was a nearly grown juvenile who died prematurely, not simply a smaller, adult female. "I study these animals as l...

New test to detect rare proteins in blood

...ibly psychiatric diseases relatively easy and more accurate compared with the current methodology, including t...he importance of FACTT is that we can still get an accurate description of the number of molecules that cause disease even when other assays cannot," says Green...

Measuring artery repair cells could become new heart disease test

A more accurate method for measuring blood levels of specialized cells that circulate in the bloodstream and repair damage to the arterial lining has been discovered by Duke University Medical Center cardiologists. These cells, known as endothelial progenitor cells ...

Robot assisted surgery more accurate than conventional surgery

... robot assisted knee surgery is significantly more accurate than conventional surgery. The team of surgeons tested whether Acrobot, a robotic assistant, could improve surgical outcomes for patients undergoing partial knee replacement. Acrobot works by helping the surgeon to line up the replacement knee parts...

Face perception is modulated by sexual orientation

...al orientation. Social communication requires the accurate analysis of the intentions of other individuals. To this end, men and women likely adopt strategies of "face reading" in order to successfully interact with potential sexual partners. Thus, it is reasonable to assume differential patterns of activati...

Liquid crystals show promise in controlling embryonic stem cells

...the cells and use cell morphology as a cue. A more accurate method uses molecular markers. Antibodies are placed against these markers to determine if they bind to the cell. That system, while more accurate, does not provide real time data and cells often have to be killed in order to analyze the markers. "T...

Scientists identify molecular structure of key viral protein

...h of an inch.) This resolution was critical for an accurate picture of how the 10,805 atoms in the structure are assembled. ...

Predicting successful outcomes in living-donor liver transplants

...iminated by the liver shortly after surgery was an accurate indicator of liver function, and therefore a reliable indicator of the outcome of the procedure. The study used a simple non-invasive device to measure the dye, making it particularly useful in treating transplant patients. The results of this stud...

Rice scientists make first nanoscale pH meter

...ogists with the first potential means of measuring accurate pH changes over a wide pH range in real-time inside living tissue and cells. "Almost every biologist I speak with comes up with one or two things they'd like to measure with this," said lead researcher Naomi Halas, the Stanley C. Moore Professor of ...

Atmospheric ozone recovering in mid-latitudes, report shows

...ed atremendous amount of data from three extremely accurate NASA satellite's instruments(SAGE I and II and HALOE) that began collecting data in 1979 and continued until 2005,with the exception of a three-year period in the early 1980s. Ground-based ozone measurements taken by NASA and NOAA from 1979 to 2005 a...

Technique speeds up detecting, treating wound bacteria

...me PCR is that we get quantitative information and accurate identification on the organisms in five hours or so, whereas the current procedure--culturing and identifying organisms by biochemical activity, etc.--can take one to several days and sometimes weeks, depending on the organism," he said. His techni...

In-home sensors spot dementia signs in elderly
