These results suggest that healthy adults may have a level of protective immune memory that can blunt the severity of infection caused by the 2009 H1N1 influenza virus.The study team was led b...
Health and Medicine |By applying the techniques to the newly completed dataset of the multi-institution Alzheimer's Disease Neuroimaging Initiative (ADNI), the scientists demonstrated that such sub-regional brain vol...
Studies and Analyses |Spore-forming bacteria, present almost everywhere in our environment, can also cause serious infectious diseases, such as tetanus, anthrax, and botulism.Now researchers from Lund University an...
Life Sciences |The fig wasps travel these distances in search of trees to lay their eggs, which offers hope that trees pollinated by similar creatures have a good chance of surviving if they become isolated through ...
Life Sciences |Researchers from Uppsala University in Sweden have now demonstrated that plasmid-based methods, which had been limited to single-cell organisms such as bacteria and yeasts, can be extended to mosses, ...
Life Sciences |Your ability to make sense of Groucho's words and Harpo's pantomimes in an old Marx Brothers movie takes place in the same regions of your brain, says new research funded by the National Ins...
Life Sciences |"Age-related hearing loss is a very common symptom of aging in humans, and also is universal among mammal species, and it's one of the earliest detectable sensory changes in aging," say...
Health and Medicine |Historically, many people, including marine scientists, have considered the abyssal plains, more than 2,000 meters below the sea surface, to be relatively isolated and stable ecosystems. Howev...
Ecology, The Environment and Conservation |Despite a 30-year lifespan that gives ample time for cells to grow cancerous, a small rodent species called a naked mole rat has never been found with tumors of any kind—and now biologists at the Univ...
Life Sciences |Statins lower cholesterol by blocking certain enzymes involved in our metabolism. However, they have also been shown to affect other important lipids in the body, such as the lipids that help proteins...
Life Sciences |Fragile X tremor/ataxia syndrome (FXTAS) is a recently recognized condition, which is actually one of the most prevalent heritable neurodegenerative diseases. It is assumed that the condition is cause...
Physics and Astronomy |The possibility that climate change might simply be a natural variation like others that have occurred throughout geologic time is dimming, according to evidence in a Proceedings of the National Acade...
Earth Sciences |These animals and others also can repair damaged heart tissue and injured structures in the eye. In contrast, humans have only rudimentary regenerative abilities, so scientists hoping eventually to de...
Life Sciences |The novelty of the newly discovered bacterial RNA repair system is that, before the damaged RNA is sealed, a methyl group is added to the two-prime hydroxyl group at the cleavage site of the damaged R...
Life Sciences |Scientists at the Singapore Immunology Network (SIgN) have determined how the master gene regulator p53 could switch a gene in a cell "on" or "off" by recognizing specific sequence...
