James Umen, Ph.D., associate member at Donald Danforth Plant Science Center, and colleagues have discovered a way to make algae better oil producers without sacrificing growth. The findings were published September 6, in a paper titled, “Synergism between inositol polyphosphates and TOR kinase signaling in nutrient sensing, growth control and lipid metabolism in Chlamydomonas,” in The Plant Cell. Umen and his team including lead author Inmaculada Couso, Ph.D., and collaborators Bradley Evans Ph.D., director, Proteomics & Mass Spectrometry and Doug Allen, Ph.D., USDA Research Scientist at the Danforth Center identified a mutation in the green alga Chlamydomonas which substantially removes a constraint that is widely observed in micro-algae where the highest yields of oil can only be obtained from starving cultures.

A new study from NOAA, the National Oceanic Atmospheric Administration, puts a new twist on a tricky question about the impact of increased oil and gas production on greenhouse gas emissions. Scientists have detected increased rates of methane emissions globally since 2007. That uptick corresponds to the rapid boom in U.S. shale gas and shale oil production, and some hypothesized that the two could be connected. But it turns out that the correlation may not necessarily be a cause.

Starting in 2019, all new or refurbished homes and apartment buildings in Europe will be required to have electric vehicle recharging stations built on the premises, according to a draft directive from the European Union.

For the first time in history, a group of bees in the U.S. will be protected under the Endangered Species Act, following a recent announcement from wildlife officials.

The group of bees, who are commonly known as yellow-faced bees because of the markings on their faces, are endemic only to the Hawaiian islands. While there are dozens of species, scientists identified several of them who are at risk of extinction and have been calling for their protection for years.

Climate change is a serious threat to humans, animals, and the earth’s ecosystems. Nevertheless, effective climate action has been delayed, partly because some still deny that there is a problem. In a new thesis in psychology, Kirsti Jylhä at Uppsala University has studied the psychology behind climate change denial. The results show that individuals who accept hierarchical power structures tend to a larger extent deny the problem.

In the scientific community there is a strong consensus that humans have significantly affected the climate and that we are facing serious challenges. But there is a lot of misinformation about climate change in circulation, which to a large part is created and distributed by organised campaigns with the aim of postponing measures that could combat climate change. And there are people who are more prone than others to trust this misinformation.

Previous research has consistently shown that it is more common among politically conservative individuals to deny climate change. In her thesis, Kirsti Jylhä has investigated this further and in more detail. Her studies included ideological and personality variables which correlate with political ideology, and tested if those variables also correlate with climate change denial.

When you go out for sushi or visit a seafood restaurant, how sure can you be that you’re really getting what you’ve ordered? Last week, Oceana released some shocking findings: Around the world, an average of one in five samples of seafood is mislabeled.

The report examined 25,000 samples worldwide and reviewed more than 200 published studies from 55 different countries. Every continent was represented apart from Antarctica. The mislabeling was present in every part of the seafood supply chain, including retail, wholesale, distribution, import/export, packaging, processing, and landing.

That’s bad news for many reasons – mislabeling makes dining dangerous for consumers (not all of these species are considered suitable for human consumption), and difficult for people who are trying to avoid mercury exposure or who simply want to dine more sustainably. In most cases, cheap fish were being passed off as more expensive varieties.

The U.S. National Flood Insurance Program, which holds policies for more than 5 million homes, is $23 billion in debt after a string of natural disasters this century. As climate change further strains the program, analysts say it is time to shift its focus from rebuilding to mitigating risk.

More than 2,100 properties across the U.S. enrolled in the National Flood Insurance Program have flooded and been rebuilt more than 10 times since 1978, according to a new analysis of insurance data by the Natural Resources Defense Council (NRDC). One home in Batchelor, Louisiana has flooded 40 times over the past four decades, receiving $428,379 in insurance payments. More than 30,000 properties in the program, run by the Federal Emergency Management Agency, have flooded multiple times over the years. Those homes, known as “severe repetitive loss properties,” make up just 0.6 percent of federal flood insurance policies. But they account for 10.6 percent of the program’s claims — totaling $5.5 billion in payments.

The new data illustrates the serious problems facing the nation’s flood insurance program. The National Flood Insurance Program (NFIP), which currently provides policies for more than 5 million American homes, is $23 billion in debt following a string of major natural disasters over the last decades, including as Hurricanes Katrina and Sandy.

Most animal lovers wouldn’t dream of harming an animal for fashion. Fur? No, thank you. Leather? I don’t think so. Yet they might be unknowingly killing sharks — and highly endangered kinds on top of that — for their beauty routine.

Unbeknownst to most, one little ingredient in products like sunscreens, moisturizing lotions, lip balms, lipsticks and face creams is responsible for the death of over three million sharks annually.

Killer ingredient

“Squalene is a naturally occurring compound found in large quantities in the liver of sharks,” explains the shark protection group Shark Trust. “A sharks’ large oily liver helps to control its position in the water column, however many cosmetics companies use the oil (and an associated compound called squalane) as a base for their moisturizing and skin care creams, lipstick and gloss, as it is non-greasy and softens skin.”

The Renewables Energy Policy Network for the 21st Century - shows that renewables are now firmly established as competitive, mainstream sources of energy in many countries around the world, closing the gap between the energy haves- and have-nots

The influence of fossil fuel corporations was strongly questioned by developing countries in the post-Paris meeting of the climate change negotiations in Bonn last week. Climate Trackers Pavlos Georgiadis, Renee Karunungan and Anna Pérez Català highlight the key issues that were debated. 

A number of developing countries, led by Ecuador, Guatemala and Bolivia are now calling for concrete measures to define how the public policy making process interacts with the private sector in climate change negotiations. What they want is special attention to be given to concerns over potential conflicts of interest between the industry and the implementation of the Paris Agreement.
