Even fish don't swim well when they're young!

...cause the fish larvae the most trouble, then it is easier to adjust rearing schemes in aquaculture and to lend a hand to endangered species", she says. ...

Ritalin packs punch by elevating norepinephrine, suppressing nerve signal transmissions

...l transmissions in the sensory pathways to make it easier to block out extraneous stimuli, a Philadelphia research team has found. Their report in the Journal of Neurophysiology helps explain how a stimulant aids people with attention deficit and hyperactivity disorders to improve their focus without incre...

Polymers show promise for lab-on-a-chip technology

... and UV radiation exposure, which could makes them easier to activate than silicon. And, perhaps most import...Ps are less expensive than silicon and potentially easier to process, Elias said. "Ultimately, we believe liquid crystalline polymers will be fully integrat...

Honey helps problem wounds

...dressings is less painful, since the poultices are easier to remove without damaging the newly formed layers of skin.' Some wounds often smell unpleasant ?an enormous strain on the patient. Yet honey helps here too by reducing the smell. 'Even wounds which consistently refused to heal for years can, in our ...

New MRI technique quickly builds 3-D images of knees

...nsin Alumni Research Foundation, also will make it easier to image parts of the body, such as the heart or abdomen, in which motion is a factor. ...

Sandia work launched on space shuttle shows live cells influence growth of nanostructures

...from unmanned aircraft. The method also makes it easier to prepare individual cells for laboratory investigation under microscopes. "Normally, to visually examine a cell, researchers use time-consuming fixation or solvent extraction techniques," says Brinker. "We can spin-coat a cell in seconds, pop the c...

MIT 'seeing machine' offers hope to blind

...ols that convey the meaning of words and make them easier to see and read. But although the SLO held promise as more than a diagnostic device, it had serious drawbacks. In addition to the prohibitive cost, the SLO is large and bulky. Goldring determined to develop a more practical machine for the broader ...

'Micro-boxes' of water used to study single molecules

...The unusually simple containment method may enable easier experiments on single molecule dynamics and perhaps lead to the development of molecule-sorting devices that might be used for medical screening or biotechnology research. The work was reported in the July 3 issue of Applied Physics Letters. The NIS...

How HIV 'exhausts' killer T cells

...ca are living in poverty and in rural areas, it is easier for us to obtain their cooperation in such studies than with patients in the United States. "It was with the key support of the Doris Duke Charitable Foundation and the Nelson Mandela School of Medicine that we have been able to build a biomedi...

A new tool against brain disease

New light microscope sharpens scientists' focus

...ologists -- a process that they anticipate will be easier when they and their microscope move to the Janelia Farm campus in the coming months. "I think we've come a long way in the last year, from two unemployed guys with just an idea to having good jobs and a good set of data," Betzig noted. "Now if we can...

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

...e surgical guidance and detect which tumors may be easier to biopsy," detailed Andrew Quon, clinical assistant professor of radiology/diagnostic radiology at California's Stanford University. "Three-dimensional fusion provides unique views of the body that internal organs typically impede," said Quon. "O...

Allergy battle could be won in five years, says scientist

... significantly better because taking a medicine is easier than rigorous housework and pills are portable." Professor Garrod, who is based within Manchester's Faculty of Life Sciences, said work on the first ADI chemical was well advanced and potential drugs could enter clinical trials as early as 2010. ...

Mapping the protein world

... the life of structural biologists worldwide a lot easier and will do even more so once the new features planned under the NIH grant have been implemented." ARP/wARP transforms 'electron density maps', produced in experiments that bombard protein crystals with X-rays, into 3-dimensional structures. "X-ray ...

Study shows frogs can play key role in stem cell research

...mphibians. But, because the African clawed frog is easier to study than mice and humans, the Edinburgh team anticipate that it will become an important research tool in their quest to understand and, ultimately, treat disease using stem cells. The results of their study are published in the current edition ...

Choosy females make colourful males

...sh prefer brightly coloured males because they are easier to see and are in better shape concludes Dutch researcher Martine Maan following her study of fish speciation in the East African Lakes. Environmental variation subsequently leads to differences in preference and eventually to speciation. Evolution...

Bone marrow may restore cells lost in vision diseases

...one marrow does regenerate the injured RPE. It was easier to track male, pigment-producing cells in female, albino recipients, Harris said. Chemical and microscopic analysis showed the cells that traveled to the injury site and transformed into RPE indeed had male genetic characteristics. Furthermore, thes...

Bacteria have their own immune system protecting against outside DNA

...r. "Now we know this is because such sequences are easier to recruit and regulate than other DNA." This research could also have major implications for the biotech industry, which uses bacteria for the production of recombinant proteins for medicine and research. These proteins, such as insulin or human gr...

New strategy developed to combat West Nile Virus

...s concentrated ?in time and space ?it does make it easier to devise control strategies. Chemical application is the most likely scenario, but because it could be applied in selected areas, it would be more cost-effective and potentially less environmentally threatening." The spread of West Nile Virus thro...

Liquorice cancer care
