Brightening prospects of using fluorescent nanotubes in medical applications

...rple color and, when analyzed, proves to contain a surprisingly uniform population of the brightest nanotubes. The researchers had expected this approach to boost the quantum efficiency by five to ten times. The fact that the improvement was considerably larger – 20 to 100 times – came as a pleasant surprise. ...

ASU research shows connection between testosterone, dietary antioxidants and bird coloration

...ne state in 35 male and female zebra finches. They surprisingly found that when they administered testosterone implants to zebra finches that it acted as a stimulant to the immune system. They went on to show that carotenoids acquired from food and circulating through the blood were changing in ways that were lin...

Resistant HIV quickly hides in infants' cells

...rug-resistant HIV transmitted from their mothers—a surprisingly high figure. Of those five, four were resistant to non-nucleoside reverse transcriptase inhibitors (NNRTIs), a common class of antiretroviral drug used to treat HIV infection and to prevent mother-to-child transmission. All had uncommon drug-resista...

Palau's coral reefs show differential habitat recovery following the 1998 bleaching event

...g that reefs off Palau, Micronesia, have recovered surprisingly well from a 1998 "bleaching" event, caused by high sea water temperatures. "The rare piece of good news in the problem of climate change is that good local management practices might aid recovery of coral reefs." Van Woesik, a profess...

Improved predictions of warming-induced extinctions sought

...many species could be at risk from global warming, surprisingly few species became extinct during the past 2.5 million years, a period encompassing several ice ages. They suggest that this "Quaternary conundrum" arises because the models fail to take adequate account of the mechanisms by which species persist in ...

Gene tests and brain imaging reveal early dementia

... deterioration two to three years later. "It's surprisingly difficult to diagnose Alzheimer's with any certainty, but things are made easier if you know who runs the greatest risk," she says. "If genetic mapping, MRI and cognitive tests all suggest approaching Alzheimer's, it might be an idea to start a cours...

Mimicking how the brain recognizes street scenes

... computer-vision systems, the biological model was surprisingly versatile. Traditional systems are engineered for specific object classes. For instance, systems engineered to detect faces or recognize textures are poor at detecting cars. In the biological model, the same algorithm can learn to detect widely diff...

Paleontologists discover new mammal from Mesozoic Era

...o its unique ear structure, Yanoconodon also has a surprisingly high number of 26 thoracic ("chest") and lumbar ("waist") vertebrae, unlike most living and extinct terrestrial mammals that commonly have 19 or 20 thoracic and lumbar vertebrae. The extra vertebrae give Yanoconodon a more elongated body form, in con...

Large size crucial for Amazon forest reserves

...sive effect of size. It does for many species, but surprisingly not for many others. The main methodological difficulty of this study, say the authors, was that birds are hard to detect. When one samples a plot of forest it is easy to miss species that actually exist there. To distinguish real absences from d...

Biologists prove critical step in membrane fusion

...icroscope, the researchers show that hemifusion is surprisingly stable in live cells. "The novelty of these results is that a live cell can maintain a hemifused state for hours, days, even months," said Julian Wong, a postdoctoral research associate in the Wessel lab and the first author of the journal article...

Baby fish 'smell their way home'

...erent reefs. To their amazement, within minutes a surprisingly high percentage of baby fish had congregated in the water flow from their home reef. "It was a lot more than you'd expect to happen by pure chance ?and it applied, in differing degrees, across several species of fish," Mike says. The fish could...

Ladybugs may be cute, but watch out when they get near wine

...is, the earliest member of the human genus, with a surprisingly small brain and distinctly protruding jaw, features commonly associated with more apelike members of the hominid family living as much as three million years ago. Dr. Bromage"s findings call into question the extent to which H. rudolfensis differ...

Man's earliest direct ancestors looked more apelike than previously believed

Anticipation plays a powerful role in human memory, brain study finds

...at means the simple act of anticipation may play a surprisingly important role in how fresh the memory of a tough experience remains. The findings of the brain-imaging study, which appear in the current issue of the Proceedings of the National Academy of Sciences, have important implications for the treatment o...

American scientist's research of life's first cells

... levels of biological organization might have been surprisingly easy during the origin of life." Born in San Diego, California, to Taiwanese-American parents, Chen majored in chemistry at Harvard University, and as an undergraduate studied molecular recognition in the laboratory of Gregory Verdine. She then en...

Mayo researchers discover HIV dependence on a human protein

...all to a pole. "It turns out that the virus needs surprisingly little p75 to integrate," says Dr. Poeschla. "Future studies will want to factor such potential potency into designs of screens for additional key cellular proteins that HIV either appropriates as partners, as in the case of p75, or schemes to evade....

The biggest bug in gut discomfort

...ontrol bacteria known to traffic to lysosomes, yet surprisingly the dyes were unable to enter vacuoles containing C. jejuni. The bug had left the conventional endocytic pathway. Watson and Galan also investigated the roles of two Rab GTPases, proteins involved in the maturation of endosomal compartments. Thes...

Microbe fixes nitrogen at a blistering 92 C

...at-loving archaeon capable of fixing nitrogen at a surprisingly hot 92 degrees Celsius, or 198 Fahrenheit, may represent Earth’s earliest lineages of organisms capable of nitrogen fixation, perhaps even preceding the kinds of bacteria today's plants and animals rely on to fix nitrogen. The genetic analysis repo...

Advance helps explain stem cell behavior

...ross said. Much of this process happens during a surprisingly short time and at very early stages of embryonic development. In mice, for instance, virtually all of the types of cells are formed in 12 days, during what would correspond to a fraction of the "first trimester" of the human gestational period, as ge...
