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 ...
Study shows how epigenetic memory is passed across generations
A growing body of evidence suggests that environmental stresses can cause changes in gene expression that are transmitted from parents to their offspring, making "epigenetics" a hot topic. Epigenetic modifications ...
Human sense of fairness evolved to favor long-term cooperation
The human response to unfairness evolved in order to support long-term cooperation, according to a research team from Georgia State University and Emory University.
Plant engineered for more efficient photosynthesis
(Phys.org) —A genetically engineered tobacco plant, developed with two genes from blue-green algae (cyanobacteria), holds promise for improving the yields of many food crops.
Human faces are so variable because we evolved to look unique
The amazing variety of human faces – far greater than that of most other animals – is the result of evolutionary pressure to make each of us unique and easily recognizable, according to a new study by ...
'Femme fatale' emerald ash borer decoy lures and kills males
An international team of researchers has designed decoys that mimic female emerald ash borer beetles and successfully entice male emerald ash borers to land on them in an attempt to mate, only to be electrocuted ...
'Most famous wheat gene' found
Washington State University researchers have found "the most famous wheat gene," a reproductive traffic cop of sorts that can be used to transfer valuable genes from other plants to wheat.
How an ancient vertebrate uses familiar tools to build a strange-looking head
If you never understood what "ontogeny recapitulates phylogeny" meant in high school, don't worry: biologists no longer think that an animal's "ontogeny", that is, its embryonic development, replays its entire ...
