Penguin biologists from around the world, who are gathered in Boston the week of September 6, warn that ten of the planet’s eighteen penguin species have experienced further serious population declines. The effects of climate change, overfishing, chronic oil pollution and predation by introduced mammals are among the major factors cited [...]
Trypanosomes are parasites responsible for many human and animal diseases, primarily in tropical climates. One disease these parasites cause, African sleeping sickness, results from the bite of infected tsetse flies, putting over 60 million Africans at risk in 36 sub-Saharan countries. The recent 1998-2001 sleeping sickness epidemics in South Sudan, [...]
Scientists at the Genome Institute of Singapore (GIS), a biomedical research institute of the Agency for Science, Technology and Research (A*STAR), and their colleagues from the National University of Singapore, Nanyang Technological University, Duke-NUS Graduate Medical School and Princeton University have recently discovered that viruses that ‘invaded’ the human genome [...]
Microbes could soon be used to convert metallic wastes into high-value catalysts for generating clean energy, say scientists writing in the September issue of Microbiology.
Researchers from the School of Biosciences at the University of Birmingham have discovered the mechanisms that allow the common soil bacterium Desulfovibrio desulfuricans to recover the precious [...]
