In September 2015, the US National Institutes of Health placed a funding moratorium on research that involves introducing human pluripotent stem cells into animal embryos. To assess attitudes on human-animal chimeric embryo research, investigators conducted a survey among 430 Americans. The results of the survey found that 82% of people are supportive of at least some parts of this research.
Depending on who you ask, geoengineering is either a threat to serious climate action, a faraway back-up plan or a necessary part of today’s climate policy. All would likely agree it is contentious. Geoengineering encompasses a broad spectrum of proposed…
If human societies don’t sharply curb emissions of greenhouse gases, Greenland’s rate of ice loss this century is likely to greatly outpace that of any century over the past 12,000 years, a new study concludes. Scientists say the results reiterate the need for countries around the world to take action now to reduce emissions, slow the decline of ice sheets, and mitigate sea level rise.
The Trump administration halted certain grant funding to select environmental organizations, including the World Wildlife Fund, which have used federal money to fund alleged human rights violations in Africa, according to an internal memo. The Department of the Interior (DOI)…
While dinosaurs ruled the land in the Mesozoic, the oceans were filled by predators such as crocodiles and giant lizards, but also entirely extinct groups such as ichthyosaurs and plesiosaurs. Now for the first time, researchers have modeled the changing ecologies of these great sea dragons.
(Technical University of Munich (TUM)) When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers suspected an impending supernova – a stellar explosion that could also cause damage on Earth. While Betelgeuse has returned to normal, physicists from the Technical University of Munich (TUM) have found evidence of a supernova that exploded near the Earth around 2.5 million years ago.
(Aarhus University) A new R&D project at Aarhus University aims to develop a camera-based AI-controlled separation system that can accurately separate plastic waste according to type. The goal is recycled plastic with a plastic purity of at least 96 per cent by polymer type and sorted according to unwanted colours and filler materials. The project is conducted in cooperation with the Danish waste industry and has received a EUR 3 million grant from Innovation Fund Denmark.
(NOAA Northeast Fisheries Science Center) Decades of data allow researchers at the NOAA Northeast Fisheries Science Center to look at predator-prey interactions in a different way: among multiple species throughout the water column. They have developed an unusually rich picture of who is eating whom off the Northeastern United States.
