Guggenheim is reserving the right for its $5.3 billion Macro Opportunities Fund — which aims for total return via fixed income and other debt and equity securities — to invest in the Grayscale Bitcoin Trust. The trust’s shares are solely invested in Bitcoin, and track the digital asset’s price less fees and expenses.

“The Guggenheim Macro Opportunities Fund may seek investment exposure to Bitcoin indirectly through investing up to 10% of its net asset value in Grayscale Bitcoin Trust,” the firm said in a filing Friday to the U.S. Securities and Exchange Commission.

Investments in Bitcoin would put Guggenheim and its Chief Investment Officer Scott Minerd in with the likes of Paul Tudor Jones and Stan Druckenmiller, who have already said they’ve put money into the digital asset. The largest cryptocurrency has had

Community conservation reserves protect fish diversity in tropical rivers — ScienceDaily

Prohibiting fishing in conservation reserves is a common strategy for protecting ocean ecosystems and enhancing fisheries management. However, such dedicated reserves are rare in freshwater ecosystems, where conservation efforts generally piggyback on the protection of terrestrial habitats and species.

Now, a collaboration between researchers from Cornell University and the University of Wisconsin-Madison has found that small, community-based reserves in Thailand’s Salween River Basin are serving as critical refuges for fish diversity in a region whose subsistence fisheries have suffered from decades of overharvesting.

The team’s paper, “A Network of Grassroots Reserves Protects Tropical River Fish Diversity,” published Nov. 25 in Nature.

The lead author is Aaron Koning, a former postdoctoral fellow with the Cornell Atkinson Center for Sustainability who is currently a postdoctoral researcher at the University of Nevada, Reno. The project was overseen by Pete McIntyre, the Dwight Webster Sesquicentennial Faculty Fellow and associate professor of natural resources

Massive greenhouse gas reserves, frozen deep under the seabed, are alarmingly now starting to thaw. That’s according to an international team of scientists whose preliminary findings were recently reported in the Guardian. These deposits, technically called methane “gas hydrates,” are often described as “fiery ice” due to the parlor trick of burning atop a Bunsen burner what appears to be ice.


The research is not yet peer-reviewed and has been controversial, with some climate scientists saying the Guardian article makes unsupported claims. We agree that findings should be peer-reviewed before they are reported. But as experts in these exact methane hydrates, we’re more sympathetic than the climate scientists towards the idea that this a serious possibility that we need to start worrying about. So although it is controversial, let’s suppose for a moment that these latest findings are real and that methane frozen below the
