...new generation of imaging agents that pinpoint the location of diseased tissue in the body. However, the question of whether these nanomaterials are toxic to living cells or organisms has not been fully answered, the researchers explain. The scientists used laboratory tests on human lung cells to show that ...

Does the desire to consume alcohol and tobacco come from our genetic makeup?

... males) use a common locus (an identifiable location on a chromosome) for alcohol and tobacco was found on chromosome (chr) 1. Also on chr 1, in an area believed to be involved with diastolic blood pressure (DBP), they found a locus for smoking. on chr 3, in the area identified as being involve...

1 of deep ocean's most turbulent areas has big impact on climate

...ek expedition aboard a French research vessel to a location close to the Azores, volcanic islands 2,000 miles east of the U.S. and west of Europe that comprise an above-sea portion of the mostly submerged Mid-Atlantic Ridge.

Innovative tagging technique may help researchers better protect fish stocks

Census of Marine Life historians detail collapse of bluefin tuna population off northern Europe

...exico will likely cause a change in the timing and location of spawning, the authors say. Companion research says the tags recorded remarkable behaviour shifts among tuna breeding in this region, including shallower, more oscillatory diving and a tendency to stay near the surface. Lingering in the region, ...

New grants bolster efforts to generate faster and cheaper tools for DNA sequencing

...g large amounts of human genome data that ties the location of sequence elements to longer-range map information. This would include information such as structural variations and aberrations associated with cancer genomes. The resulting data could be linked to information produced by other emerging sequencing...

Learning to evolve: With a little help from my ancestors

...which store each item of information in a specific location in the computer's memory chip, neural networks store each item distributed over many neuronal connections. If information is stored as distributed representations then evolution is accelerated. This may help explain how complex motor skills, such as ...

Call for EU to launch major project to map out all our proteins

...he possibility of deducing the precise number, and location in the genome, of the genes coding for proteins. This is much more complex than simply mapping the genome from end to end because it involves detecting all proteins even though some are present only in very small amounts, while some are confined to s...

Scientists a step closer to understanding how anaesthetics work in the brain

...part human. The chimeras were used to identify the location of the precise amino acid to which the anaesthetic binds on the potassium channel, giving the team a clearer picture than ever before of the precise mechanism by which anaesthetics work. This kind of research, explains Professor Franks, is importa...

Nodal status is best predictor of outcome after neoadjuvant therapy for esophageal cancer

Several tissue samples from each patient were extracted during surgery and were subsequently examined for extent of residual...

Researchers witness natural selection at work in dramatic comeback of male butterflies

"But regardless of which of the two sources of the suppressor gene is correct, natural selection is the next step. The suppressor gene allows infected females to produce males, these males will mat...
