Flies can be more than pesky picnic crashers, they may be potent pathogen carriers, too, according to an international team of researchers.
A study of Darwin's finches, which live on the Galapagos Islands in the Pacific Ocean, has revealed direct genetic evidence that new species can arise in just two generations.
Cooperatively breeding birds and fish may have evolved the adaptive ability to reduce the size of their eggs when helpers are available to lighten the parental load, a new study suggests. The findings indicate that in some species, the social environment may influence female reproductive decisions even prior to the birth of offspring.
Research led by Oxford University, published today in Science, highlights the accelerating pressure on measuring, monitoring and managing water locally and globally. A new four-part framework is proposed to value water for sustainable development to guide better policy and practice.
While the world focuses on controlling global warming caused by CO2 emissions from fossil fuels, less attention has been paid to the capacity of vegetation and soils to take up and store carbon. A remote field site in the Norwegian mountains is improving our understanding of carbon cycling in high-latitude alpine areas.
Through a few clever molecular hacks, researchers at Columbia University Medical Center have converted a natural bacterial immune system into a microscopic data recorder, laying the groundwork for a new class of technologies that use bacterial cells for everything from disease diagnosis to environmental monitoring.
The flow of China's carbon emissions has reversed according to new research led by scientists at the University of East Anglia (UEA). The study estimates the carbon implications of recent changes in the country's economic development patterns and role in international trade since the global financial crisis.
Original concerns that cloning caused early-onset osteoarthritis in Dolly the sheep are unfounded, say experts at the University of Nottingham and the University of Glasgow. The team, who published last year's Nottingham Dollies research which showed that the 8 year-old Nottingham 'Dollies' had aged normally, have now published a radiographic assessment of the skeletons of Dolly herself, Bonnie (her naturally conceived daughter) and Megan and Morag (the first two animals to be cloned from differentiated cells).
The most dramatic divergence between humans and other primates can be found in the brain, the primary organ that gives our species its identity. However, all regions of the human brain have molecular signatures very similar to those of our primate relatives, yet some regions contain distinctly human patterns of gene activity that mark the brain's evolution and may contribute to our cognitive abilities, a new Yale-led study has found.
Researchers at Sanford Burnham Prebys Medical Discovery Institute (SBP) have identified a signaling pathway that is essential for angiogenesis, the growth of new blood vessels from pre-existing vessels. The findings, published in Nature Communications, may improve current strategies to improve blood flow in ischemic tissue, such as that found in atherosclerosis and peripheral vascular disease associated with diabetes.
