Evolution of Old World fruit flies on three continents mirrors climate change
Fast-warming climate appears to be triggering genetic changes in a species of fruit fly that is native to Europe and was introduced into North and South America about 25 years ago.
Uranium 'pearls' before slime
Since the discovery a little more than a decade ago of bacteria that chemically modify and neutralize toxic metals without apparent harm to themselves, scientists have wondered how on earth these microbes do ...
Ancient Global Warming Drove Early Primates' Dispersal
The continent-hopping habits of early primates have long puzzled scientists, and several scenarios have been proposed to explain how the first true members of the group appeared virtually simultaneously on Asia, Europe and ...
Biological safety lock for genetically modified organisms
The creation of genetically modified and entirely synthetic organisms continues to generate excitement as well as worry.
Harnessing data from Nature's great evolutionary experiment
There are 3 billion letters in the human genome, and scientists have endlessly debated how many of them serve a functional purpose. There are those letters that encode genes, our hereditary information, and ...
Predatory sea snails produce weaponized insulin
As predators go, cone snails are slow-moving and lack the typical fighting parts. They've made up for it by producing a vast array of fast-acting toxins that target the nervous systems of prey. A new study ...
Roller coaster geese: Insights into high altitude bird flight physiology and biomechanics
Roller Coaster migratory flights of geese give unique insights into bird physiology and biomechanics at high altitudes.
