Love or kill thy neighbor? New study into animal social behavior
A theoretical study led by the University of Exeter has shed new light on the conditions that lead to the evolution of spite or altruism in structured populations.
Can monogamy undermine intelligence?
Yes. At least over 100 generations in Drosophila melanogaster vinegar flies.
Enzyme controls transport of genomic building blocks
Our DNA and its architecture are duplicated every time our cells divide. Histone proteins are key building blocks of this architecture and contain crucial information that regulates our genes. Danish researchers ...
Amazon's canopy chemistry is a patchwork quilt
In many ways, plants act as chemical factories, using energy from sunlight to produce carbon-based energy and taking nutrients from the soil in order to synthesize a wide variety of products. Carnegie scientists ...
Maize and bacteria: A 1-2 punch knocks copper out of stamp sand
Scientists have known for years that together, bacteria and plants can remediate contaminated sites. Ramakrishna Wusirika, of Michigan Technological University, has determined that how you add bacteria to ...
Enhanced photosynthesis is crucial for improving bioplastic yields from cyanobacteria
Traditional petrochemical plastics are made from non-renewable fossil fuels and cannot be readily assimilated back into the environment at the end of their useful life. Thus, there is considerable interest ...
Ninety-five per cent of world's fish hide in mesopelagic zone
An international team of marine biologists has found mesopelagic fish in the earth's oceans constitute 10 to 30 times more biomass than previously thought.
Breakthrough in hybrid species science
(Phys.org) —Massey University scientists have discovered a universal law that explains how hybrid species survive and thrive.
Trawling restrictions crucial to preserve biodiversity
A Western Australian study has found that restricting trawling to 20-40 per cent of fishing areas in Shark Bay can mitigate the long-term impacts of commercial trawling in the region.
Genetic molecular mechanisms of neural development identified
Neural development is an extremely complex and highly orchestrated process, involving genetic cascades during which dozens of genes are activated at specific times and places. Polycomb-group (PcG) proteins ...
Yellowstone: Bison slaughters done for the season
Yellowstone National Park administrators say shipments of wild bison to slaughter are done for the winter after almost 600 animals were removed in an effort to shrink their numbers.
Europe's largest badger study finds rare long-distance movements
Animal movement is a key part of population ecology, helping us understand how species use their environment and maintain viable populations. In many territorial species, most movements occur within a home range. Occasionally, ...
Sea turtles 'lost years' mystery starts to unravel
Small satellite-tracking devices attached to sea turtles swimming off Florida's coast have delivered first-of-its-kind data that could help unlock they mystery of what endangered turtles do during the "lost ...
A single gene, doublesex, controls wing mimicry in butterflies
A single gene regulates the complex wing patterns, colors and structures required for mimicry in swallowtail butterflies, report scientists from the University of Chicago, March 5 in Nature. Surprisingly, the ge ...
