Circling #momotombo at sunset while hanging out the side of a gigantic heli that didn’t seem phased by the #cloudcap on the #volcano.

Apparently this is one of the most dangerous things to fly near. None of us knew that at the time (and we actually flew through the top on the last pass) but it sure was an amazing experience. (at Momotombo, Leon, Nicaragua)

The nomination of unqualified non-scientist Sam Clovis is a powerful illustration of the Trump administration’s hostility both to science and to the rule of law.

The visual spectrum of birds includes UV

“It is now known that many birds, probably most, have some degree of UV vision, which they use to find both food and partners. The berries that some feed on have a UV bloom, and European kestrels can track their vole prey from the UV reflecting off the voles’ urine trails. The plumage (or parts of it) in hummingbirds, European starlings, American goldfinches, and blue grosbeaks reflects UV light, often more markedly in males than females. In certain species, like the blue grosbeak, the degree of UV reflectance may also reflect male quality, though females don’t currently use this aspect of plumage to discriminate between potential partners…”

US military agency invests $100m in genetic extinction technologies

Technology could be used to wipe out malaria carrying mosquitos or other pests but UN experts say fears over possible military uses and unintended consequences strengthen case for a ban

They’re investing in Gene Drives.

(For a really good intro to gene drives and the opportunities and threats they pose: x) As the headline states, it can be used as an “extinction technology”. (It basically quickly forces genes to spread through a population.)

The article pretty much nails it when they point out that everyone is nervous about a branch of the military investing in this. Cause really, anyone looking into this should have the greatest amount of oversight possible. This technology can be used for a lot of good, but also a lot of bad. And most importantly, even the best intentions could have disastrous effects with this technology.

DARPA - the gov’t’s fringe science division - basically argues that a big part of the rationale is to be ready for others who might use it in a negative way. Which does seem important, to be fair. I guess the question becomes, ‘who watches the watchmen?’

Highlights:

A US military agency is investing $100m in genetic extinction technologies that could wipe out malarial mosquitoes, invasive rodents or other species…

The use of genetic extinction technologies in bioweapons is the stuff of nightmares, but known research is focused entirely on pest control and eradication…

Some UN experts, though, worry about unintended consequences. One told the Guardian: “You may be able to remove viruses or the entire mosquito population, but that may also have downstream ecological effects on species that depend on them.”

“My main worry,” he added, “is that we do something irreversible to the environment, despite our good intentions, before we fully appreciate the way that this technology will work.”…

“Darpa is not and should not be the only funder of gene-editing research but it is critical for the Department of Defense to defend its personnel and preserve military readiness,” he said.

Darpa believes that a steep fall in the costs of gene-editing toolkits has created a greater opportunity for hostile or rogue actors to experiment with the technology.

“This convergence of low cost and high availability means that applications for gene editing – both positive and negative – could arise from people or states operating outside of the traditional scientific community and international norms,” the official said. “It is incumbent on Darpa to perform this research and develop technologies that can protect against accidental and intentional misuse.”

Just 1°C of ocean warming can upend marine ecosystems 

For 9 months, the researchers monitored the distribution and growth of marine species that settled on the heated boxes and compared them with those that lived above unheated boxes. All it took was one look to notice the difference, Ashton says. In the 1°C increase experiment, a single species of moss animal, Fenestrulina rugula, doubled its growth rate. Within 2 months, the calciferous shelves it created dominated the community, the team reports today in Current Biology. What’s more, overall species diversity plummeted by 50%.
