Research team identifies new Alzheimer's gene

...s throughout the human genome to provide a clearer picture of how life works and ultimately allow better clinical management of patients,” said Dr. Dietrich Stephan, Director of TGen’s Neurogenomics Division and the paper’s senior author, “These new, robust tools may eventually allow us to improve our abilit...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

... anti-malarial drug resistance genes is painting a picture of how the parasite escapes destruction by most of the agents now used against it, he said., When a malaria parasite is transmitted through a mosquito bite, the mosquito injects the parasite into skin or blood, which then travels to the liver wi...

Ancient DNA traces the woolly mammoth's disappearance

...n combination with the results on other species, a picture is emerging of extinction not as a sudden event at the end of the last ice age, but as a piecemeal process over tens of thousands of years involving progressive loss of genetic diversity,” said Dr. Ian Barnes, of Royal Holloway, University of London....

Dual-imaging technique useful before -- and during -- brain surgery

... “We can essentially show patients a color-coded picture of their brain and explain to them where their tumor is in relation to areas that control critical functions like expressive speech, movement and vision,” says Leach. “This can help alleviate the patient’s apprehension and help explain what will happ...

Rising skin cancer rates are more likely to affect wealthy people, says 12-year review

... numbers and sample numbers to provide an accurate picture of cancer levels” says co-author Dr Susannah Hoey from the Dermatology Department at the Royal Victoria Hospital, part of the Belfast Health and Social Care Trust. “The three skin cancers we looked at all increased with age, with the exception of...

'Lucky 13' as new gene discovery offers further hope for childhood blindness

...ucky thirteenth' as we are building a much clearer picture of what causes the disorder." Professor Inglehearn believes that lebercilin may be involved in moving proteins from the inner to outer segments of photoreceptors in the retina. Protein transport is essential within retinal photoreceptor cells as t...

Undergraduate research shows leaderless honeybee organizing

...om its breeding queen mother, the research shows a picture of the queen as a passive egg layer whose own behavior is programmed, with changes dictated by signals delivered by older workers. This does not mean, however, that the colony is controlled by a key group of experienced bees either. The worker bee...

Exploring the dark matter of the genome

...ntromere in the middle." Obtaining a more complete picture of the sequence of heterochromatin is clearly a crucial step toward a better understanding of genome functions. Karpen notes that one intensively studied and puzzling problem in chromosome biology will benefit enormously from the new findings: e...

Scientists close in on missing carbon sink

...hat a team of scientists analyzed them to obtain a picture of sources and sinks of carbon on a global level. The research team compared the air samples to estimates of airborne carbon dioxide concentrations generated by the computer models. The scientists found that most of the models significantly undere...

Putting feelings into words produces therapeutic effects in the brain

... making different emotional expressions. Below the picture of the face they either saw two words, such as “angry” and “fearful,” and chose which emotion described the face, or they saw two names, such as “Harry” and “Sally,” and chose the gender-appropriate name that matched the face. Lieberman and his c...

Definitive evidence found of a swimming dinosaur

...ité de Nantes, France, the S-shaped prints paint a picture of a large floating animal clawing the sediment as it swam in approximately 3.2 meters of water. Ripple marks on the surface of the site indicate the dinosaur was swimming against a current, struggling to maintain a straight path. "The dinosaur sw...

Want to save polar bears? Follow the ice

... ice extent and concentration since 1978 to form a picture of polar bear habitat history as well as where this habitat most likely remain in the future under global warming projections. When combined with meteorological data, the researchers hope to distinguish short-term, seasonal effects and large scale ph...

Philandering female felines forgo fidelity

...nges that encompass several female ranges. “The picture that emerges is that of wide-ranging females mating with a number of males, which could be an advantage in terms of helping to maintain genetic diversity,” said ZSL’s Dada Gottelli, the study’s lead author. Findings from the study are significant ...

Lessons from the orangutans: Upright walking may have begun in the trees

...y and moved on two legs. "Our findings blur the picture even further," said Robin Crompton of the University of Liverpool in Liverpool, Great Britain, who is one of the study's authors. "If we're right, it means you can't rely on bipedalism to tell whether you're looking at a human or other ape ancestor. ...

Protein enables discovery of quantum effect in photosynthesis

...and inaccurate," said Fleming. "It gives the wrong picture of how the process actually works, and misses a crucial aspect of the reason for the wonderful efficiency." The taco shell is a sort of "middleman" in the antenna system, sandwiched in between a larger antenna and a molecule called the Reaction Ce...

Gene malfunctions cause schizophrenia, depression symptoms in mice

...gether are strikingly consistent with the emerging picture from clinical and basic studies of DISC1 as a common genetic and biologically plausible risk factor for major mental illness," concluded Clapcote and colleagues. They wrote that "our findings lend further credence to the growing recognition that schi...

Toxoplasmosis infection trick revealed by scientists

...ars. This means that the team have a more detailed picture than ever before of exactly how the parasite recognises and attacks host cells in the body. Professor Steve Matthews from Imperial College London’s Division of Molecular Biosciences, one of the paper’s authors, explains the significance of the re...

DOE JGI sets 'gold standard' for metagenomic data analysis

...e 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." Nikos Kyrpides,...

Decoding protein structures helps illuminate cause of diabetes

... can vouch for the difficulty of capturing a clear picture of a moving target. When it comes to molecules, however, sometimes the motion is exactly what scientists want to see - for example, to understand the pathological protein mis-folding and assembly that seem to underlie a host of human disorders, in...
