Discovery of the first protein-based toxin in an amphibian

Researchers in China have discovered the first protein-based toxin in an amphibian - a 60 amino acid neurotoxin found in the skin of a Chinese tree frog. This finding may help shed more light into both the evolution of amphibians and the evolution of poison.

Molecules wrestle for supremacy to dictate the physical state of superstructures

Research at the University of Liverpool has found how mirror-image molecules gain control over each other and dictate the physical state of superstructures.

Human brain distinctly separates living and non-living objects for processing

For unknown reasons, the human brain distinctly separates the handling of images of living things from images of non-living things, processing each image type in a different area of the brain. For years, many scientists have assumed the brain segregated visual information in this manner to optimize processing the images themselves, but new research shows that even in people who have been blind since birth the brain still separates the concepts of living and non-living objects.

Similarities found in the way neural circuits linked to vision process information in both sighted and blind since birth

The ability to recognize visually presented objects relies on a critical neural pathway called the ventral stream. Previous imaging studies of the human brain have demonstrated that the sight of nonliving objects, such as tools and houses, activates different regions within the ventral stream than the sight of living things, such as animals and faces. It is not known whether category-specific neural responses in the ventral stream depend on visual experience.

Seattle Genetics reaches milestone under collaboration agreement with MedImmune

Seattle Genetics, Inc. (NASDAQ:SGEN), announced today that it has achieved a milestone under its antibody-drug conjugate (ADC) collaboration agreement with MedImmune, LLC, a wholly owned subsidiary of AstraZeneca. The milestone was triggered by MedImmune’s initiation of a phase I clinical trial of MEDI-547, its anti-EphA2 ADC for solid tumors.

Zara's Center at Bulawayo provides relief to AIDS orphaned children

Rachael Plutzik seems like an ordinary teenager and student growing up in New York City. She likes hanging out with her friends and family, singing in her a cappella group, playing the guitar, and reading Harry Potter books.

Novel approach for developing an AIDS vaccine

Researchers at the Yerkes National Primate Research Center, Emory University, believe conventional vaccine strategies should not be the only avenue explored in the development of an effective AIDS vaccine.

Scientists study affect of carbon nanoparticles on fruit flies

Carbon nanoparticles are widely used in medicine, electronics, optics, materials science and architecture, but their health and environmental impact is not fully understood.

Pending health care reform should not distract from making medical technology investments

In spite of the tremendous attention being paid this summer to health care reform, it is critical that investments in medical technology startups not go into a “holding pattern,” but continue unabated. So says ONSET Ventures partner Rob Kuhling.

Innovative diabetes drug discovery partnership

The Juvenile Diabetes Research Foundation said today that it has entered into a novel collaborative research agreement with the Genomics Institute of the Novartis Research Foundation (GNF) to create a diabetes drug discovery and development platform.

Set-shifting and the on-line processing of relative clauses in Parkinson's Disease

The study of the neural basis of language has largely focused on regions in the cortex - the outer brain layers thought by many researchers to have expanded during human evolution.

Eye movements of Parkinson’s disease patients during sentence comprehension support subcortical role in processing syntax

The study of the neural basis of language has largely focused on regions in the cortex – the outer brain layers thought by many researchers to have expanded during human evolution.

Discovery of unique 'DNA signature' in human sperm - unlocks egg's fertility

Drs David Miller and David Iles from the University of Leeds, in collaboration with Dr Martin Brinkworth at the University of Bradford, have found that sperm writes a DNA signature that can only be recognised by an egg from the same species. This enables fertilisation and may even explain how a species develops its own unique genetic identity.

Research may bring powerful new test for inflammatory lung diseases

Chronic inflammatory lung diseases like chronic bronchitis and emphysema are a major global health problem, and the fourth leading cause of death and disability in developed countries, with smoking accounting for 90% of the risk for developing them.

Health-related quality of life in chronic kidney disease patients

Chronic kidney disease (CKD) can significantly lessen patients' quality of life, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). Certain types of patients - women, diabetics, and those with a history of heart complications - are most affected.

New links between dreams and psychosis could revive dream therapy in psychiatry

Similarities in brain activity during lucid dreaming and psychosis suggest that dream therapy may be useful in psychiatric treatment, a European Science Foundation (ESF) workshop has found. This is strengthened by the potential evolutionary relationship between dreams and psychosis.

New software provides a better understanding of how viruses evolve

Computer scientists and biologists at the University of Southampton have used the combined power of computing resources within the institution to develop software which provides a better understanding of how viruses evolve.

Scientists create new way to study brain function

Scientists at Duke University and the University of North Carolina have devised a chemical technique that promises to allow neuroscientists to discover the function of any population of neurons in an animal brain, and provide clues to treating and preventing brain disease.

New research tool – map of genomic variation for diagnosing and identifying genetic problems

Genetics researchers have unveiled a powerful new resource for scientists and health providers studying human illnesses -- a reference standard of deletions and duplications of DNA found in the human genome. Drawn from over 2,000 healthy persons, the study provides one of the deepest and broadest sets of copy number variations (CNVs) available to date, along with a new research tool for diagnosing and identifying genetic problems in patients.

Research suggests core nuclear pore elements shared by all eukaryotes

For perhaps 1.8 billion years after life first emerged on Earth, a sort of evolutionary writer's block stalled the development of organisms more complicated than single cells. Then, a burst of experimental creativity about 1.7 billion years ago brought the cell nucleus onto the scene, stashing the cell's genetic material inside a protective inner membrane and setting the stage for the evolution of more sophisticated creatures from yeast, say, to plants and human beings.
