Rib cartilage from human donors is well tolerated as a grafting material in nasal plastic surgery and yields positive functional, structural and cosmetic results, even in complex cases, according to...
New research into the mechanisms of gene regulation
A team of scientists has taken a large step toward unraveling how regulatory proteins control the production of gene products during development and growth. They focused specifically on the complex...
Scientists find molecular trigger that helps prevent aging and disease
Researchers set out to address a question that has been challenging scientists for years: How does dietary restriction produce protective effects against aging and disease? And the reverse: how does...
How the brain filters out distracting thoughts to focus on a single bit of information
Researchers in Norway have discovered a mechanism that the brain uses to filter out distracting thoughts to focus on a single bit of information.

Beyond sunlight: Explorers census 17,650 ocean species between edge of darkness and black abyss
Census of Marine Life scientists have inventoried an astonishing abundance, diversity and distribution of deep sea species that have never known sunlight - creatures that somehow manage a living in...
Clearer view of how eye lens proteins are sorted
New research reveals how proteins that are critical for the transparency of the eye lens are properly sorted and localized in membrane bilayers. The study analyzes how interactions between lipid...
Sweet as can be: How E. coli gets ahead
Scientists have discovered how certain bacteria such as Escherichia coli have evolved to capture rare sugars from their environment giving them an evolutionary advantage in naturally competitive environments like the...
Termites create sustainable monoculture fungus farming
Food production of modern human societies is mostly based on large-scale monoculture crops, but it now appears that advanced insect societies have the same practice. Our societies took just ten...
Tree-eating bugs threaten Monarch butterfly in Mexico
The mysterious Monarch butterfly, which migrates en masse annually between Canada and Mexico, is now facing a new peril: another insect thriving in Western Mexican forests.
Fish 'at risk' in acidified ocean
Fish reared in water acidified by CO2 may become "fatally attracted" to the smell of their predators, say scientists.
