Conceptualizing a cyborg

...apt the movements. The central feature of the proposed interface is the ability to create transplantable living nervous tissue already coupled to electrodes. Like an extension cord, of sorts, the non-electrode end of the lab-grown nervous tissue could integrate with a patient's nerve, relaying the signal...

Smokers quit after damage to brain region

...mans," Naqvi said. In the 1990s, Antonio Damasio proposed the insula, a small island enclosed by the cerebral cortex, as a "platform for feelings and emotion." The Science study shows that the pleasure of smoking appears to rest on this platform. "It's really intriguing to think that disrupting this regio...

Does evolution select for faster evolvers?

...ed into another. The idea was ridiculed when first proposed more than 50 years ago, but the advent of drug-resistant bacteria and subsequent discoveries, including the identification of a specialized protein that bacteria use to swap genes, has led to wide acceptance in recent years. "We know that the majo...

New study: Preterm birth causes one-third of all infant deaths

...icial reporting system indicates. The researchers proposed a new method to determine the contribution of premature birth to infant mortality. They reviewed causes of infant death and combined conditions, such as respiratory distress syndrome, which frequently occur in premature babies. This new method double...

MRSA toxin acquitted: Study clears suspected key to severe bacterial illness

...nfections, several research groups previously have proposed that PVL is the key virulence factor. But new evidence strongly suggests that is not the case. A study led by NIAID researchers at Rocky Mountain Laboratories (RML) in Hamilton, MT, shows that the two major epidemic CA-MRSA strains and the same st...

Researchers seek to design first treatment for neuroAIDS

... tested as a treatment for Parkinson's disease. He proposed that Cephalon make the drug available for the study of the drug's effect on neuroAIDs. CEP-1347 has already proven capable of reversing the neurotoxic effects of HIV proteins in living cells, according to research published in the July 1, 2006, editi...

Common ancestry of bacterium and plants could be key to an effective new treatment for chlamydia

...etween the Chlamydia bacterium and plants had been proposed by others," said Thomas Leustek," a professor in the department of plant biology and pathology at Rutgers' School of Environmental and Biological Sciences (formerly Cook College). "But we have now described a specific example demonstrating the common...

Small, smaller, smallest -- The plight of the vaquita

...e Governments of the Upper Gulf to support actions proposed by an international vaquita recovery team. These Governments have argued that no action should be taken until a second survey for a new abundance estimate shows definitively that the population is declining. But the question of how often new estim...

An advanced genetic diagnostic method for multiple myeloma

...t the University of Navarra, Borja Sáez Ochoa, has proposed a new genetic diagnostic method for multiple myeloma (MM), a type of bone marrow cancer, which permits the detection of this disease in earlier stages. The dissertation of this biologist, produced in the Department of Genetics of the School of Scien...

Replacing insulin is top-ranked breakthrough foreseen for health in developing world

...a commitment would provide the means to pursue the proposed Grand Challenges in Non-communicable Diseases initiative and provide incentives to develop regenerative medicine therapies that are relevant, accessible and affordable to the developing world. "The threat of non-communicable diseases in developing c...

Pattern of human Ebola outbreaks linked to wildlife and climate

...at initially seemed disparate and unrelated. They proposed that the virus first spread southwest across Gabon. It then looped back toward the northeast from sites in western or central Gabon and caused the most recent outbreaks in RoC. "If the spread of the Ebola virus follows its current northeastward p...

Biologists probe the machinery of cellular protein factories

...les and more than 50 different proteins. Noller proposed in the early 1970s that the RNA component was resp... "It was a completely heterodox view when we first proposed it, but it is now the accepted paradigm," said Noller, who directs the Center for Molecular Biology ...

Nanotech tools yield DNA transcription breakthrough

...tretch to reach adjacent DNA segments (as had been proposed two decades ago in models termed "transient excursions" and "inchworming"). Instead, the researchers showed that the machine remains stationary and pulls adjacent DNA segments into itself. "The study of molecular machines and the dynamics of their...

New dwarf buffalo discovered by chance in the Philippines

...odied species elsewhere in the tropics such as the proposed new hominid, Homo floresiensis, found on the Indonesian island of Flores in 2003. "Whether or not Homo floresiensis ultimately is shown to be a new dwarf hominid species, discovery of this new fossil water buffalo provides additional evidence that dw...

Therapeutic role found for carbon monoxide

...onset of certain inflammatory conditions was first proposed in 1998. Since then, numerous studies have shown that when administered at low, non-toxic concentrations prior to such procedures as organ transplant surgery or balloon angioplasty, CO provides potent protective effects against organ rejection or blo...

Plutonium or greenhouse gases? Weighing the energy options

Ewing recently co-edited a book, "Uncertainty Underground," that reviews uncertainties in the analysis of the long-term performance of the Yucca Mountain repository. Pluto...

Most widely used organic pesticide requires help to kill

... long-held view of Bt's mode of killing. "What was proposed as a hypothesis in one paper became cited as proven in another and no one seemed to go back to the original literature until now." Handelsman is a Howard Hughes Medical Institute Professor in the UW-Madison department of plant pathology. The new ...

High dopamine transporter levels not correlated with ADHD

...n New York indicate that levels of a brain protein proposed as a diagnostic marker for attention-deficit hyperactivity disorder (ADHD) are not positively correlated with the disease. In fact, the study found lower levels of these "dopamine transporter" proteins in certain brain regions of ADHD patients compar...

Where we change our mind

...oncluded the researchers. "This fits well with the proposed role of these regions in decision making, which is likely to be crucial in complex real-world environments. We also illustrate the utility of statistical model-based inference and regression in delineating key task parameters that may be represented ...
