One species, many genomes

...ax Planck Institute for Developmental Biology. The results were surprising: The extent of the genetic differences far exceeds the expectations for such a streamlined genome, as the scientists write in this week’s edition of Science magazine. Arabidopsis plants from different geographical origins differ in...

Nicotine rush hinges on sugar in neurons

... that allow signals to pass between neurons. The results reveal an important role for the sugar molecules in such proteins. “Our studies fill a major gap in the field and set a new paradigm,” said Lin Chen, associate professor of molecular and computational biology at USC. Many existing theories, which...

Cigarette smoke alters DNA in sperm, genetic damage could pass to offspring

...t could potentially be inherited by offspring. The results of their study are published in the June 1 issue of Cancer Research, a journal of the American Association for Cancer Research. “Here we are looking at male germline mutations, which are mutations in the DNA of sperm. If inherited, these mutation...

Old memory traces in brain may trigger chronic pain

While the physical pain appeared to be reduced 30 percent – their emotional suffering completely disappeared. Rat are nocturnal animals that prefer to be in...

Gene therapy delivery of nerve growth factors reverses erectile dysfunction in animal model

Even if a patient receives a nerve-sparing procedure during surgery, recovery from ED after radical prostatectomy may take a long time. In this study, which was led by Joseph C. Glorioso, III, Ph.D., chair of the...

...ack zones” comparable with wound areas. The set of results obtained from subsequent work, seeking to identify the genes involved in producing the unknown signal molecule that plays the role of Nod factor, prompted the team’s hypothesis that a molecule similar to a plant hormone (4), cytokinin, could act in t...

Research team identifies new Alzheimer's gene

...iated with other genes, including APOE4. The study results appear in the June 7 issue of the prestigious peer-reviewed journal, Neuron. Alzheimer’s disease is the most common form of disabling memory and thinking problems in older people. The progressive neurological disorder afflicts an estimated 5 million...

Dirty snow may warm Arctic as much as greenhouse gases

Limiting industrial soot emissions and switching to cleaner-burning fuels would leave snow brighter, he says. New snow falls each year, and if it contained fewer impurities, the ground would brighten...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...spewing many new parasites into the blood. A fever results from the infection, and this is followed by repeated cycles of mounting parasitic reproduction within red blood cells and accompanying fever. During red blood cell infection, P. falciparum degrades the hemoglobin in the red cell, producing a toxic by...

Darwin once proposed a co-evolutionary "race" to explain how natural selection might account for the evolution of very long nectar spurs in flowers, said Hodges. "In Darwin's race, plants with the...
