“#Honeybee lives shortened after exposure to two widely used pesticides” One cage from each of the three experimental groups in an Oregon State University honeybee study. The control cage on the far left has more live bees than the cages in which the bees were exposed to Sivanto (middle) and Transform (far right). Credit: Priyadarshini…
“#The nexus between economic inequality and social welfare” Credit: CC0 Public Domain Equity (or, its counterpart, inequity) plays a fundamental role in the evaluation of the different dimensions of social welfare. But how can we consider and compare its different dimensions? These issues are in fact traditionally considered and compared across individuals—be it within national…

“#Cattle vs. hippopotamus: Dung in rivers of the savannah” Hippos in the Mara River in Kenya. Credit: Gabriel Singer In many regions of the world, populations of large mammalian herbivores have been displaced by cattle breeding—for example, in Kenya, hippos by large herds of cattle. This can change aquatic ecosystems due to significant differences in…
“#Agroforestry is ‘win win’ for bees and crops, study shows” Agroforestry example with woody plants next to crops Credit: Alexa Varah Planting woody plant species alongside crops could double the number of insect pollinators helping farmers produce food, new research has demonstrated for the first time. The study, led by the University of Reading and…
“#New papers describe discoveries at MBARI’s long-term deep-sea research site off California” MBARI scientists use the Benthic Rover (top left) and ROV Doc Ricketts (top right) to study animal communities at Station M. Some of the seafloor animals living in the area include large sea cucumbers in the genus Psychropotes (bottom left), sponges, and a…
“#Physicists document method to improve magnetoelectric response” Credit: CC0 Public Domain University of Arkansas physicists have documented a means of improving the magnetoelectric response of bismuth ferrite, a discovery that could lead to advances in data storage, sensors and actuators. Bismuth ferrite, or BFO, has long been of interest to scientists because its functional properties…
“#Tunisia’s first satellite to highlight country’s technology” In this photo taken on Thursday Nov. 28, 2019, Mohamed Frikha, CEO of Tunisia’s Telnet Group, speaks with the Associated Press in Tunis. Telnet is preparing to launch the country’s first satellite, which will improve the provision of data from the earth, including climate information. The small satellite…
