Modern genetics confirm ancient relationship between fins and hands
Paleontologists have documented the evolutionary adaptations necessary for ancient lobe-finned fish to transform pectoral fins used underwater into strong, bony structures, such as those of Tiktaalik roseae. ...
Devising a way to count proteins as they group
A new study from Indiana University-Purdue University Indianapolis and University of California Berkeley researchers reports on an innovative theoretical methodology to solve "the counting problem," which is key to understanding ...
Intensive agriculture may have exacerbated drought in ancient Maya city
Researchers use X-ray video of guineafowl walking through poppy seeds to create a 3-D model of how tracks get made
Getting here from there: Mitochondrial genome clarifies North American migration models
Time, energy and storage capacity determine the measurement accuracy of the 'cell computer'
Researchers from FOM institute AMOLF have discovered what determines the accuracy with which cells can measure chemical concentrations. They described the results of their research in two publications: on ...
Seasoned policymakers drive the fairest bargain of all
Is an experienced policymaker a more rational and a more self-interested bargainer than the average person? That is what nearly all prior research has assumed. But a new study from the University of California, San Diego ...
Leaves of ancient carnivorous plants found in Baltic amber
American mastodons made warm Arctic, subarctic temporary home 125,000 years ago
Existing age estimates of American mastodon fossils indicate that these extinct relatives of elephants lived in the Arctic and Subarctic when the area was covered by ice caps—a chronology that is at odds ...
Study shows pre-human ancestors adapted to metabolize ethanol long before humans learned about fermentation
Study shows increase of CO2 in the atmosphere is lower than predicted because of plants
Turing's theory of chemical morphogenesis validated 60 years after his death
Alan Turing's accomplishments in computer science are well known, but lesser known is his impact on biology and chemistry. In his only paper on biology, Turing proposed a theory of morphogenesis, or how identical ...
Algae biofuel can help meet world energy demand, researchers say
(Phys.org) —Microalgae-based biofuel not only has the potential to quench a sizable chunk of the world's energy demands, say Utah State University researchers. It's a potential game-changer.
