Transcription is a cellular process by which genetic information from DNA is copied to messenger RNA for protein production. But anticancer drugs and environmental chemicals can sometimes interrupt this flow of genetic information by causing modificati…
By discovering how certain viruses use their host cells to replicate, microbiologists have identified a new approach to the development of universal treatments for viral illnesses such as meningitis, encephalitis, hepatitis and possibly the common cold.
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…
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.
Rather than trying to kill bacteria outright with drugs, researchers have discovered a way to disarm bacteria that may allow the body’s own defense mechanisms to destroy them. “To understand this strategy one could imagine harmful bacteria being like D…
Results from a novel experimental therapy for type 1 diabetes that boosts parts of the healthy immune system were just reported.
Like recruiters pitching military service to a throng of people, scientists are developing drugs to recruit disease-fighting proteins present naturally in everyone’s blood in medicine’s war on infections, cancer and a range of other diseases.
Scientists have now identified the first substance in smokeless tobacco that is a strong oral carcinogen, a health risk for the 9 million users of chewing tobacco, snuff and related products in the U.S., and called upon the federal government to regula…
A comprehensive analysis of the Cascadia Subduction Zone off the Pacific Northwest coast confirms that the region has had numerous earthquakes over the past 10,000 years, and suggests that the southern Oregon coast may be most vulnerable based on recur…
A new analysis of the common accretion-disk model explaining how planets form in a debris disk around our Sun uncovered a possible reason for Earth’s comparative dryness. The study found that our planet formed from rocky debris in a dry, hotter region,…
