Scientists unlock secret of what makes plants flower

The study reveals the likely mechanism by which the Arabidopsis plant flowers in response to changes in day length. Earlier research had shown that plants' leaves perceived seasonal changes in day length, which triggers a long-distance signal to travel through the pla...

New research says winning a Nobel Prize adds nearly 2 years to your lifespan

New research by the University of Warwick reveals that a Nobel Prize brings more than just cash and kudos - it can also add nearly two years to your life. The research by Professor Andrew Oswald, an economist at the University of Warwick, and Matthew Rablen, (a former Warwick postgraduate researche...

Racing neurons control whether we stop or go

...in, more quickly than their comrades. New research reveals that a similar race goes on in our brains, with impulse control being the big winner. "The research provides new insights into how the brain controls movements, which helps explain the impulsivity of people with attention deficit and hyperactivity d...

Proteins important in Alzheimer's, Parkinson's disease travel in the slow lane

..., like car pooling" speculates Roy. "Our study reveals novel aspects of axonal transport of an important class of proteins, namely the slow component-b proteins, and also opens up new avenues for investigating axonal transport defects in neurodegenerative diseases," concludes Roy....

World's largest flower evolved from family of much tinier blooms

...urnal Science. Their genetic analysis of rafflesia reveals that it is closely related to a family that includes poinsettias, the trees that produce natural rubber, castor oil plants, and the tropical root crop cassava. The team from Harvard University, Southern Illinois University, the Smithsonian Instituti...

Manipulating nature: Scientists query wildlife birth-control method

...to be short-lived." Professor Cooper's research reveals that than in 27 out of 32 immunocontraceptive control trials around the world, 10 per cent of animals remained fertile because they were unresponsive to self-antigens. His second concern is that the technique is effectively a form of genetic engin...

Study shows hope for early diagnosis of Alzheimer's

...he entire ERP signal, not just the P300 indicator, reveals markers that previously have not been associated with Alzheimer’s disease. The teams conducted several experiments, ultimately evaluating the parietal and occipital regions of the brains of 71 patients, some already diagnosed with Alzheimer’s and ...

New technologies coming too fast for Indian farmers

...se to 62 percent from 12 percent. Stone's research reveals that the increase resulted not from traditional farming methods of testing seed for efficacy, but from a pattern of "social learning" ?farmers relying on word of mouth to choose seeds. "Very few farmers were doing experimental testing, they were ju...

Link found between immune system and high plasma lipid levels

...sease, ," said Fu, senior author on the paper. "It reveals a quite unexpected role of hepatic T cells in lipid metabolism." "Those with inflammatory problems such as lupus, rheumatoid arthritis and inflammatory bowel syndrome have a higher incidence of cardiovascular disease, often associated with elevate...

Analysis of rhesus monkey genome uncovers genetic differences with humans, chimps

...ecial section of the journal Science, the analysis reveals that the three primate species share about 93 percent of their DNA, yet have some significant differences among their genes. In its paper, the Rhesus Macaque Genome Sequence and Analysis Consortium, supported in part by the National Human Genome Res...

How fish species suffer as a result of warmer waters

... just published in the scientific journal Science, reveals that a warming induced deficiency in oxygen uptake and supply to tissues is the key factor limiting the stock size of a fish species under heat stress. Scientists of the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven investi...

Misclassified for centuries, medicinal leeches found to be 3 distinct species

...e the species Hirudo medicinalis, but new research reveals they are actually a closely related but genetically distinct species, Hirudo verbana. The study also shows that wild European medicinal leeches are at least three distinct species, not one. The results appear in the April 10, 2007, online version o...

Spreading viruses as we breathe

...earch by Queensland University of Technology which reveals airborne viruses can spread far and wide. Professor Lidia Morawska, director of QUT's International Laboratory for Air Quality and Health, said the study dispelled the myth that viruses emitted from humans only travel a metre in the air. Profess...

Catching cancer's spread by watching hemoglobin

...laser beams across the sample, a process that then reveals the outlines and contours of blood vessels. By taking images at different depths and stacking these images layer by layer, the researchers can reconstruct 3-D images of blood vessels. A major advantage of the technique is that it is "label-free,...

Detecting cold, feeling pain: Study reveals why menthol feels fresh

...ed on-line in the journal "Nature" (May 30, 2007), reveals one of the key mechanisms by which the body detects temperature sensation. But in so doing it also illuminates a mechanism that mediates how the body experiences intense stimuli – temperature, in this case – that can cause pain. As such, the rece...

Putting feelings into words produces therapeutic effects in the brain

...r" A new brain imaging study by UCLA psychologists reveals why verbalizing our feelings makes our sadness, anger and pain less intense. Another study, with the same participants and three of the same members of the research team, combines modern neuroscience with ancient Buddhist teachings to provide the f...

In nature, proteins sweep up nanoparticles

...in the June 15, 2007 issue of the journal Science, reveals that the proteins travel far from the microbes that produce them, and then amass metal nanoparticles into piles that are too large to be swept away by underground currents. Precisely how and why the bacteria undertake this bit of housecleaning remain...
