Using brain scans, researchers find evidence for a two-stage model of human perceptual learning

...up the cars into two distinct categories. This was easy at first, Riesenhuber said, because the cars were obviously not alike, but then the researchers began to "tighten the screws" by making the two categories increasingly more similar. "Over the course of the training, the participants got better at...

Large size crucial for Amazon forest reserves

...to detect. When one samples a plot of forest it is easy to miss species that actually exist there. To distinguish real absences from detection failures, the authors used state of the art statistical methods developed by James Nichols and colleagues, at the U.S. Geological Survey's Patuxent Wildlife Resear...

Cancer tip -- Nanoparticles can damage DNA, increase cancer risk

... ?in electronics, textiles and sporting goods ?and easy to work with in the laboratory setting. "We observed both dose-dependent and time-dependent increases in DNA damage in breast cancer cells exposed to either aqueous colloidal silica or C60 fullerenes," Pacheco said. "The DNA damage could potent...

New research shows that flu is a trigger of heart attacks

...care. In contrast, the flu vaccine is inexpensive, easy to administer and could save thousands of lives every year." Prof Madjid ?who directs a research lab dedicated to the effect of flu on the cardiovascular system ?pointed out that the implications of the research were even more important with a loo...

Are journal rankings distorting science?

...rnals on only their most important papers. It’s easy to criticise bibliometrics, but we should attempt to refine them and debate in parallel how we can track academic careers and encourage fewer, but better studies that affect the wider community, he concludes....

Cheaper, better disease treatments expected from faster approach to developing antibodies

...pril 15, in Nature Biotechnology. Bacteria are easy to grow in an inexpensive broth. As a result, harmless forms of the bacterium E. coli have already been used as factories to produce antibodies (protective proteins of the human body that fight viruses, cancer cells and other harmful agents). However...

Scientists create dual-modality microbeads to improve identification of disease biomarkers

...ions can be added to the beads. "Adding them is as easy as adding the nanoparticles into the solution. You just have to make sure the nanoparticle surface is hydrophobic so that it interacts with the beads," said Sathe. The primary biomedical applications for this new technology will be to detect cance...

Triplex assay used to assay duplex genomic DNA

... of automatic in solution assay. The instrument is easy to program, self-cleaning and inexpensive. Daksis indicated that she expected to soon publish data on the use of the Genome Flow® instrument to carry out triplex assaying of genomic samples for pathogens or SNPs. ...

Speeding 'fingertip' discovery -- 20 years of protein info in 1 place

...lready was published, and there was just no clean, easy way of doing that because there were reports all over the place. “That’s when we decided to go through and consolidate just about everything on phosphorylation that was out there.? Working with human kidney cells, the researchers fished out the...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

...an integrated computational environment to support easy access to a set of universal tools, novel algorithmic approaches and tracking mechanisms for reproducibility at a global level. Having Asian researchers involved in the TATRC-funded project lends an added dimension of urgency and depth to the U.S...

'Ancestral eve' was mother of all tooth decay

...ocess called coevolution." "It is relatively easy to trace the evolution of S. mutans, since it reproduces through simple cell division," says Caufield, who gathered over 600 samples of the bacterium on six continents over the past two decades. His final analysis focused on over 60 strains of S. mu...

A revolution in the monitoring of unborn babies

...art for signs of potential danger. It is small and easy to use so that mother’s-to-be can keep a regular check on their baby’s heart beat without having to go into hospital and be attached to a machine. No other technology allows them to do this. It took 15 years of pioneering work and enterprise, with f...

Fish can determine their social rank by observation alone, study finds

...ly adaptive." When A. burtoni males fight, it's easy to spot the winner. Mature males have a menacing black stripe, or eyebar, on their face. After a fight, the winner retains his showy appearance, but the loser's eyebar temporarily disappears as he tries to flee his more aggressive opponent. To te...

Plants do not emit methane

...kes the carbon released from the plants relatively easy to detect. Thus, if plants are able to emit methane, it will contain the heavy carbon isotope and can be detected against the background of lighter carbon molecules in the air. Six plant species were grown in a 13C-carbon dioxide atmosphere, satur...

Stem cell therapy shows promise in regenerating damaged muscle in heart attack patients

...gical procedures, but this one was very simple and easy for the patient. Schaer says the cells were grown in culture to very high numbers, allowing a single donor's cells to treat thousands of patients. "The cells have the ability to expand, or multiply, under controlled conditions, and the expanded ce...

Growth hormone to boost athletic performance risks diabetes

...ll round the world, say the authors, because it is easy to buy online and difficult to detect in screening tests—unlike anabolic steroids. The authors believe that this is the first reported case of diabetes associated with the use of high dose growth hormone, and urge anyone taking high doses to regul...

Syphilis rate on rise in US gay, bisexual men

...arge increase among another group." It is still easy to cure syphilis, but it can cause serious medical problems, including death if untreated. In addition, officials worry that gay men will get syphilis and become more susceptible to HIV infection, although statistics have not made it clear if that is...

Opening windows may be the best way of preventing transmission of airborne infection

...ludes that although “natural ventilation is not an easy solution for patients in countries where winters are cold ?the current practice of sealing in the local environment is probably the wrong route for hospital wards? ...

Reversing cancer cells to normal cells

...at develops outside the body (making it especially easy to simply watch development), and the fact it develops organs and tissues comparable to those in humans, such as heart, kidney, pancreas, bones and cartilage.) Using the zebrafish model, and the extraordinary technologic advances made in microsc...
