Confocal imaging promises early detection of skin cancer

...ysical cuts and resulting scars, looking at layers slice by slice.?The technology has been around for 50 years, but only recently been used in the life sciences area. Because it calls on lasers and high-end imaging, confocal technology is expensive. One project goal was to reduce the manufacture costs ?by...

Health benefits of a Christmas brandy

...tant part of the mix. "So when you are enjoying a slice of brandy-infused fruit cake or a drink of good quality brandy over Christmas you can put your mind at rest that this amber liquid isn't too bad for you at all. In moderation, of course." Red wine is famously known as an effective antioxidant so it ...

K-State researchers study gene regulation in insects

...ience. "We wanted to know how the same genes that slice a space like a loaf of bread can also add slices one at a time," Brown said. According to Brown, the groundwork for this research was laid about 20 years ago when scientists first learned about the genes that regulate embryonic development in the fr...

Scaled-down genome may power up E. coli's ability in lab, industry

Terahertz imaging may reduce breast cancer surgeries

... spectrum. The researchers found that by placing a slice of excised breast tissue on a special quartz plate and exposing it to terahertz light, the light waves reflected from the tissue contained unique information about its state. The researchers were able to distinguish both invasive and noninvasive brea...

Scientists identify gene involved in stem cell self-renewal in planaria

No matter how you slice it, the freshwater planarian possesses an amazing ability to regenerate lost body parts. Chop one into pieces, and each piece can grow into a complete planarian. The flatworm relies upon a population of stem cells to accomplish this remarkable feat; ...

Fantastic Voyage: A new nanoscale view of the biological world

...," Lechene says. "Imagine looking into a building, slice by slice. You can see not only that it contains apartments, but also that each apartment contains a refrigerator. You can see that there are tomatoes in the refrigerator of one apartment, and potatoes in the refrigerator of another. You can count ho...

Good times ahead for dinosaur hunters, according to U of Penn scientist's dinosaur census

...f there was a decline within that six-million-year slice of time before the extinction event." Their estimates for total dinosaur diversity take into account the number of dinosaurs already found, the rate of discovery and potential richness of the fossil locations that can be reasonably explored. They h...

Bypassing eggs, flu vaccine grown in insect cells shows promise

...ic. Taking eggs out of the process would likely slice one or two months off the production process, Treanor said. In case of a bird-flu pandemic, that would allow manufacturers to ramp up vaccine production more quickly than if they had to wait for the production of millions of eggs. Not relying on chic...

DNA analysis suggests under-reported kills of threatened whales

... analysis ?characterized by DNA profiles from each slice of whale meat ?which was developed by one of the co-authors of the study, Justin Cooke at the Center for Ecosystem Management Studies in Gutach, Germany. Although capture-recapture analysis is widely used to estimate the abundance of living whales in...

CT scan reveals ancient long-necked gliding reptile

...formation about the animals. Even then, no single slice contained the entire skeleton. Post-scan processing produced an amazingly clear, if somewhat flattened, image of a small reptile with a long neck and swept back wings. Gliding behavior evolved several times in reptiles and is present in the Indon...
