Ancient ants arose 140-168 million years ago

...rometry was used to demonstrate the feasibility of detecting norovirus particles in the purified concentrates. ...d public health preparedness as a tool for rapidly detecting norovirus--a category B bioterrorism agent--and other viral public health threats. The study is publ...

Plants used to detect gas leaks, from outer space!

...s of the plant appear stressed in satellite images detecting reflected light. This remote-sensing technology can be used to detect any type of stress that causes asphyxiation of the plant roots. Steven and his colleagues are already considering other uses for the detection system. One such application may ...

Technique speeds up detecting, treating wound bacteria

...anism," he said. His technique is also useful in detecting flora that can't easily be grown in culture because no one's been able to determine just what the bacteria like in the way of nutrients and environmental conditions. The earlier the lab staff has answers, the earlier the correct treatment can begin...

Memory loss affects more of the brain than previously thought

...aying closer attention to frontal lobe function in detecting people at risk for AD and may also point to new preventive strategies," said co-principal investigator P. Murali Doraiswamy, M.D., chief of the Division of Biological Psychiatry in the Department of Psychiatry at Duke. Both researchers caution that ...

In-home sensors spot dementia signs in elderly

...ame time as memory changes leading to dementia. By detecting subtle activity changes over time in the natural setting of an elder's home, researchers hope to more effectively identify when elders are starting to have trouble. Hayes and colleagues in the OHSU Oregon Center for Aging & Technology - ORCATEC...

Purdue creates new low-cost system to detect bacteria

...ht scattering off objects for applications such as detecting impurities on silicon wafers in computer chip manufacturing and measuring the size and speed of fuel droplets in jet engines. "We adapted some ideas from that research to build a scatterometer for food safety, and now we're using the second generat...

Mitochondrial DNA sequencing tool updated

...gives you more to work with and a better chance of detecting mutations that might be associated with a developing cancer." Dr. Maitra said that despite the original Mitochip's 96 percent success rate assigning base calls, there was room for improvement. Led by Drs. Shaoyu Zhou and Keyaunoosh Kassauei, the ...

'Micro-boxes' of water used to study single molecules

...licate protein that survived the shaking process), detecting the fluorescence signal from dye and protein molecules, and observing the transfer of energy from one end of a specially treated DNA molecule to the other. Water offers several advantages over other methods for containing single molecules, such as ...

Seeing the serpent

...g the stakes and forcing primates to get better at detecting them. "There's an evolutionary arms race between the predators and prey. Primates get better at spotting and avoiding snakes, so the snakes get better at concealment, or more venomous, and the primates respond," Isbell said. Some primate groups l...

Magnetism and mimicry of nature hold hope for better medicine, environmental safety

...he method could aid in more quickly and accurately detecting and analyzing dangerous chemicals if they were intentionally introduced into a public environment. It also could improve monitoring systems in factories and other industrial operations where potentially hazardous chemicals are in use. The research ...

New GI technologies improve internal organ visualization

...procedures were considered moderately effective in detecting sources of intestinal bleeding. Efficacy rates for DBE and CE were comparable in detecting ulcers, blood vessel abnormalities that cause bleeding and large masses, but DBE was more effective ...

Smooth sailing: 'cruise ship virus' tackled by UH, Baylor College of Medicine

...lectors," Ruchhoeft said. "If we're successful in detecting the Norwalk virus, it opens up the possibility of creating a similar diagnostic tool for a variety of other infectious diseases." ...

Researchers show how brain decodes complex smells

...ging. The imaging technique maps brain activity by detecting changes in reflected light from the brain with a sensitive camera. To start, the researchers separated and identified the volatile compounds in each odor with gas chromatography. "A complex mixture like urine has at least a hundred separate compound...

Acidity in the brain could hold the key to stroke treatment

Development of a new technique for detecting brain damage caused by stroke has been boosted up by a £1m grant to scientists at The University of Manchester. Professor Gareth Morris of the School of Chemistry and Professor Risto Kauppinen of the University of Birmingham are to lead the developme...

UCI scientists find chlorine may contribute to ozone formation

...rs made extremely sensitive chlorine measurements, detecting the chemical at levels as low as three parts per trillion. Results showed that chlorine is present in the atmosphere both day and night, and that its levels fluctuate with little regularity. Saltzman and Finley couldn't pinpoint the cause of these c...

Smell of success for nanobiosensors

... with different odorants, the system is capable of detecting odorants at concentrations that would be imperceptible to humans. "Our tests showed that the nanobiosensors will react to a few molecules of odorant with a very high degree of accuracy. Some of the results of the trials surpassed even our expectatio...

Speeding the search for elusive chromosomal errors

...onal genetic tests have limited resolving power in detecting many chromosomal arrangements. In karyotyping, chromosomes are stained and examined under microscopes, but only larger rearrangements are visible, such as extensive deletions, or the presence of an extra chromosome, as occurs in Down syndrome. Anothe...

Large-scale genomics project will hunt genes behind common childhood diseases
