(Karlsruher Institut für Technologie (KIT) ) Increasing drought and heat seriously affect plants. In the Upper Rhine area, for example, climate change results in the development of new plant diseases, an example being Esca, a disease that causes vines to die. Researchers of Karlsruhe Institute of Technology (KIT) and partners have now launched the DialogProTec project that focuses on new approaches to plant protection without herbicides and fungicides. In collaboration with colleagues from Germany, France, and Switzerland, the researchers are conducting research in dialog with winegrowers, farmers, and industry.
(University of New South Wales) The DNA sequencing of a healthy German shepherd offers scientists new insight into the evolution of the domestic dog while also enabling dogs to be screened for hip and other diseases much more accurately.
(University of Illinois at Urbana-Champaign, News Bureau) This is the story of three bird species and how they interact. The brown-headed cowbird lays its eggs in other birds’ nests and lets them raise its young — often at the expense of the host’s nestlings. To combat this threat, yellow warblers have developed a special ‘seet’ call that means, ‘Look out! Cowbird!’ In a new study, researchers report that red-winged blackbirds respond to the seet call as if they know what it means.
Sturgeons lived on earth already 300 million years ago and yet their external appearance seems to have undergone very little change. A team of researchers has now succeeded in sequencing their genome, delivering a missing piece of the puzzle essential to understanding the ancestry of vertebrates.
(University of Nebraska-Lincoln) Ancient crocodilian ancestors that abandoned land for water nearly 200 million years ago supposedly got larger because they were released from the constraints of gravity, territory and diet. But a new study from the University of Nebraska-Lincoln’s Will Gearty suggests that the upper bounds of size in aquatic vs. landlocked crocs were similar — and that smaller aquatic species got larger mostly to avoid freezing in the frigid, heat-stealing depths.
The origin of digits in land vertebrates is hotly debated, but a new study suggests that human hands likely evolved from the fins of the Elpistostege, a fish that lived more than 380-million-years ago.
(Linköping University) Researchers at Linköping University have discovered a quantum phenomenon that influences the formation of free charges in organic solar cells. ‘If we can properly understand what’s going on, we can increase the efficiency’, says Olle Inganäs, professor emeritus.
