Picking up on the smell of evolution
UA researchers have discovered some of the changes in genes, physiology and behavior that enable a species to drastically change its lifestyle in the course of evolution.
Scientists identify patterns of RNA regulation in the nuclei of plants
When the human genome was first sequenced, experts predicted they would find about 100,000 genes. The actual number has turned out to be closer to 20,000, just a few thousand more than fruit flies have. The ...
Fruit colours evolved to please picky birds, study says
Tropical Asian birds have a penchant for red and black—a proclivity that likely prompted jungle plants to sprout fruit in these colours, scientists said on Thursday.
Wakati solution aims to extend produce shelf life
Tiny particles, big impact? Researchers are investigating how ingesting nanoparticles may influence health
Researchers at Binghamton University believe understanding nanoparticles' ability to influence our metabolic processing may be integral to mediating metabolic disorders and obesity, both of which are on the ...
Study reveals fruit flies exhibit the building blocks of emotion
A fruit fly starts buzzing around food at a picnic, so you wave your hand over the insect and shoo it away. But when the insect flees the scene, is it doing so because it is actually afraid? Using fruit flies ...
Getting more out of nature: Genetic toolkit finds new maximum for crop yields
Scientists at Cold Spring Harbor Laboratory (CSHL) today announced a new way to dramatically increase crop yields by improving upon Mother Nature's offerings. A team led by Associate Professor Zachary Lippman, ...
More than just X and Y: A new genetic basis for sex determination
Men and women differ in plenty of obvious ways, and scientists have long known that genetic differences buried deep within our DNA underlie these distinctions. In the past, most research has focused on understanding ...
Manganese speeds up honey bees
Asked to name one way people have changed the environment, many people would probably say "global warming." But that's really just the start of it.
It's the pits: Ancient peach stones offer clues to fruit's origins
Anyone who enjoys biting into a sweet, fleshy peach can now give thanks to the people who first began domesticating this fruit: Chinese farmers who lived 7,500 years ago.
Fruit fly genetics reveal pesticide resistance and insight into cancer
For being so small, fruit flies have had a large impact on genetic research. Thomas Werner, an assistant professor of biological sciences at Michigan Technological University, has bridged the miniscule and ...
New theorem determines the age distribution of populations from fruit flies to humans
The initial motivation was to estimate the age structure of a fruit fly population, the result a fundamental theorem that can help determine the age distribution of essentially any group.
DNA 'spool' modification affects aging and longevity
Research on a modified protein around which DNA is wrapped sheds light on how gene regulation is linked to aging and longevity in nematodes, fruit flies and possibly humans.
Fruit flies show mark of intelligence in thinking before they act
Fruit flies 'think' before they act, a study by researchers from the University of Oxford's Centre for Neural Circuits and Behaviour suggests. The neuroscientists showed that fruit flies take longer to make ...
