The insect vector always bites twice

...been assessed beforehand by standard entomological capture techniques. All the children involved in the study showed a higher level during the period of most intense transmission, in September. The antibody rate proved also to be associated with the risk of occurrence of a malarial attack in the following th...

Catching cancer's spread by watching hemoglobin

...es. If the imaging is fast enough, researchers can capture snapshots of blood flow in individual vessels. Moving beyond mere imaging, the technique can detect the difference between oxygen-carrying hemoglobin (oxyhemoglobin) and oxygen-lacking hemoglobin (deoxyhemoglobin). This is important for monitoring tu...

Hearts of male and female rainbow trout are different

...ectioned and stained. Light microscopy was used to capture images of ventricle layers and analyzed for layer cross-sectional areas. Lactate concentration and net lactate release from cardiac tissue was also examined. Results The researchers found: ventricle strips from males and females h...

DOE JGI sets 'gold standard' for metagenomic data analysis

...eover, you don't have enough sequence from each to capture an accurate picture of the entire community, so you only get a glimpse of the identities of multiple genomes. All the publications to date have made the assumption that these tools will work as efficiently for metagenomes, "but we really didn't know....

Decoding protein structures helps illuminate cause of diabetes

...s-folding, Zanni says. The group now plans to capture series of snapshots during individual folding reactions to identify multiple phases as the proteins convert from an unordered mishmash into flat sheets, then coil into fibers. "No matter how fast they're moving, we can take pictures of them," say...

Executable biology -- Computer science sheds light on animal development

...his picture into a dynamic representation that can capture time-dependent processes. Results from the model can then be compared to data from the lab, revealing gaps in our understanding of the processes taking place. Researchers can use the model to test hypotheses that would fill in the missing pieces in s...

Bones in motion: Brown scientists to create new 3-D X-ray system

...tailed 3-D images, but CT scanners are too slow to capture rapid motion. Cinefluoroscopy, a technique that uses X-rays to view objects, can produce moving images in two dimensions, but not 3-D. An orthopedic surgeon trying to figure out the best way to repair a torn knee ligament or an evolutionary biolog...

Imaging pinpoints brain regions that 'see the future'

...on functional magnetic resonance imaging (fMRI) to capture patterns of brain activation as college students were given 10 seconds to develop a vivid mental image of themselves or a famous celebrity participating in a range of common life experiences. Presented with a series of memory cues, such as getting...

A rarity among arachnids, whip spiders have a sociable family life

...s) in front tipped with stilettos that are used to capture prey. The first pair of legs has developed into long whiplike feelers that are three to four times longer than the remaining three pairs of legs. The exceptionally flexible whips can move 360 degrees around their bodies and are covered with hairs tha...

Scientists discover new, readily available source of stem cells

...ossibility that within this cell population we can capture true stem cells?' The answer is yes." Atala and colleagues discovered a small number of stem cells in amniotic fluid ? estimated at 1 percent ?that can give rise to many of the specialized cell types found in the human body. The scientists believe...

Scientists unveil piece of HIV protein that may be key to AIDS vaccine development

...0s and eventually made the protein stiff enough to capture a picture of it in complex with b12. They saw that b12 binds gp120 at the same point where gp120 initially attaches to CD4. Unlike the gp120-CD4 interactions, however, b12 can latch onto the site of CD4's first contact without requiring a shape chang...

Genes and biomarkers that allow doctors to choose the right therapy for the right patient

With the library, Dr. Diaz and his colleagues could select peptides that bind to tumors that are affected by a combination of radiation and tyrosine kinase inhibitor therapy, but not to tumors that ...

Bats prey on nocturnally migrating songbirds

Finally, owls, as typical night-active predators, never forage in the open space: moving prey is detected from substrates through passive-listening of rustling noises...
