WWF captures first-ever photo of wild rhino on Borneo

See the picture in the original press release A motion-triggered camera trap set up in a remote jungle has captured the first-ever photo of a rhino in the wild on the island of Borneo, World Wildlife Fund and the Sabah Wildlife Department announced today. The rh...

Coming soon: 3-D imaging that flies 'through' and 'around' cancer

...ing cancer cells. The CT scan generates a detailed picture of internal anatomy, locating and revealing the size and shape of abnormal cancer growths. When these two results are fused together, the functional data from the PET imaging is correlated with anatomy on the CT images to provide a single detailed an...

Pathway toward gene silencing described in plants

...t, inferring that it came into the act second. The picture that emerged from this logical approach is that Pol IVa gets things started, churning out RNA that then goes to the nucleolus where it is acted on by RDR2, which turns the single-stranded RNA into double-stranded RNA. The Dicer-like 3 protein, DCL3 ...

...rs of subseafloor sediment samples. "Building a picture of ancient climatic events is a lot like putting together a jigsaw puzzle, and what ACEX allowed us to do was fill in a blank section of the PETM picture," said Gerald Dickens, a Rice University geochemist and co-author, who conducted the initial, sh...

Beekeepers work hard for the honey, despite changing tupelo forest

...lo honey. "We're hoping to paint a comprehensive picture of the challenges that face the beekeepers," Stallins said. "I don't think the public knows how hard it is to produce honey. We want more awareness of the social context of beekeeping and how environmental change and sociopolitical and economic facto...

Researchers show how brain decodes complex smells

...ce, assembling the signals until it recognizes the picture is a cookie? To find answers, the Duke researchers exposed mice to different odors and measured response of neurons across the olfactory bulb with intrinsic signal imaging. The imaging technique maps brain activity by detecting changes in reflected ...

Cells use mix-and-match approach to tailor regulation of genes

...e, has given us a much more revealing and detailed picture of how cells orchestrate gene regulation to cope w...aid Ideker. "We're far from understanding the full picture of gene regulation in a cell, but this new information should give scientists who are interested in ...

New light microscope sharpens scientists' focus

...s of single molecule images that go into each PALM picture is cumbersome. With the camera snapping one to two pictures each second, it can take two to 12 hours to image a single sample. Activating more molecules per frame would reduce the number images that must be collected, and making the molecules brighte...

Structure determined for p53 tumor suppressor protein as bound to DNA for anti-cancer activity

... "The bottom line is that we now have a detailed picture of how p53 binds DNA," says Ronen Marmorstein, Ph.D., a professor in the Gene Expression and Regulation Program at Wistar and senior author on the study. "Given the fact that p53 is an important tumor suppressor that is mutated in the majority of hum...

Researchers discover which organs in Antarctic fish produce antifreeze

...sues to hybridize with an AFGP gene probe. A clear picture of strong AFGP mRNA expression came into focus in the pancreatic tissues in all notothenioids tested. The use of cDNA cloning and sequencing showed that the mRNA all encode secreted AFGPs. An RNA analysis from tissues of a single notothenioid unveil...

New findings offer more complete view of breast cancer gene mutations in US population

...l Institutes of Health today provided the clearest picture yet of the prevalence in the U.S. population of mutations in two genes associated with an increased risk of breast cancer. The genes are called Breast Cancer 1 (BRCA1) and Breast Cancer 2 (BRCA2). In addition, the study identified key predictors for ...

Completed genome set to transform the cow

...cause it provides researchers with a more complete picture of the genes in a cow and how variations in the DNA code influence desirable production traits. "We can use this data to identify those genes that are involved in important functions like lactation, reproduction, muscling, growth rate and disease ...

Tiny airborne particles are a major cause of climate change

...of atmospheric aerosols to provide a comprehensive picture of how they may be affecting our climate. Cloud formation is dependent upon the presence of small amounts of aerosols such as sea salt and desert dust. These tiny particles serve as the seeds around which water vapor in the air condenses, forming ...

The bigger picture This study adds to the scientific knowledge of what physiological factors limit performance at altitude, including the role that cardiac output plays, Friedlander said. For instance, physiologists don't know why some people have trouble at altitude...

APS lecturer shows rare video of 'teacher-student' immune cell interactions in live animal

The saying goes that a picture is worth a thousand words. But these pictures could one day be worth much more -- the lives saved by the development of new vaccines. Harvard University researcher Ulrich H. von Andrian showed the immune system of a live mouse being challenged by a ...

Avian flu modeled on supercomputer, explores vaccine and isolation options for thwarting a pandemic
