Poxviruses, a group of DNA-containing viruses that includes smallpox, are responsible for a wide range of diseases in humans and animals. They are highly virulent and able to cross species barriers, yet how they do so has been largely a mystery because…
Scientists have discovered a phenomenon never seen before in plants while studying molecular changes inside tree cells as wood is formed.
A recent study brings new insights to an area of ion channel regulation: whether voltage-gated potassium (Kv) channels can be regulated by physiological changes to PIP2.
Scientists have devised a new technique for examining the binding kinetics of membrane proteins.
Scientists have found that calorie restriction — a diet composed of approximately 30 percent fewer calories but with the same nutrients of a standard diet — does not extend years of life or reduce age-related deaths in a 23-year study of rhesus monke…
Scientists in Denmark have solved an old puzzle, which since the 1960s from many sides has been regarded as impossible to complete. The challenge was to solve the structure of the protecting protein complex that forms when hemoglobin is released from r…
Two parasitic wasp species show similar memory consolidation patterns in response to rewards of different quality, providing evidence that the reward value affects the type of memory that is consolidated.
In evaluating the bioactive compounds of Illinois blueberry and blackberry wines, scientists have found compounds that inhibit enzymes responsible for carbohydrate absorption and assimilation. And that could mean a tasty way to help people with diabete…
Scientists have sequenced the genome of one of the iconic Galapagos finches first described by Charles Darwin. he genome of the medium ground finch (Geospiza fortis) is among the first of a planned 100 genomes of vertebrate species to be sequenced and …
Birds of a feather flock together and — according to a new analysis — so do their lice. A study of the genetic heritage of avian feather lice indicates that their louse ancestors first colonized a particular group of birds (ducks or songbirds, for ex…
A new study shows that if you’re a juvenile moose trying to make it in the real world, you can’t beat an overprotective mom.
Researchers report the development of a mouse model of Fukuyama’s muscular dystrophy that copies the pathology seen in the human form of the disease.
