Since Carnegie Institution's Barbara McClintock received her Nobel Prize on her discovery of jumping genes in 1983, we have learned that almost half of our DNA is made up of jumping genes -- called transposons. Given their ability of jumping around the genome in developing sperm and egg cells, their invasion triggers DNA damage and...
The National Toxicology Program (NTP) concluded there is clear evidence that male rats exposed to high levels of radio frequency radiation (RFR) like that used in 2G and 3G cell phones developed cancerous heart tumors, according to final reports released today. There was also some evidence of tumors in the brain and adrenal gland of...
Changes in land use negatively affect bee species richness and diversity, and cause major shifts in species composition, reports a recent study of native wild bees, conducted at the Sierra de Quila Flora and Fauna Protection Area and its influence zone in Mexico.
Having registered a total of 14,054 individual bees representing 160 species, 52 genera,...
The world's smallest flightless bird can be found on Inaccessible Island in the middle of the South Atlantic. Less than 100 years ago, researchers believed that this species of bird once wandered there on land extensions now submerged in water, and therefore named it Atlantisia. In a new study led by biologists at Lund University...
Actively managed conifer forests may also provide important habitat for the pollinators that aid the reproduction of food crops and other flowering plants around the globe.
An international collaboration, led by Jim Rivers of Oregon State University, has established a roadmap for future research aimed at better understanding the role that managed conifer forests in temperate...
