World Energy Outlook 2021 – Analysis - IEA

Eat This, Not That 13 October, 2021 - 04:15am

"The social and economic benefits of accelerating clean energy transitions are huge, and the costs of inaction are immense."

The World Energy Outlook makes use of a scenario approach to examine future energy trends relying on the WEM. For the World Energy Outlook 2021 (WEO-2021), four scenarios were modelled: the Net Zero Emissions by 2050 Scenario (NZE), the Announced Pledges Scenario (APS), the Stated Policies Scenario (STEPS), and the Sustainable Development Scenario (SDS).

This year, the full World Energy Outlook report (PDF) is provided free of charge. In addition, we are also providing a WEO-2021 Free Dataset that includes global data for all scenarios (SDS, APS, STEPS, NZE) and selected data for key regions and countries for 2030 and 2050, as well as historical data for 2010, 2019 and 2020. Access to this dataset will be free of charge for non-commercial usage. An Extended Dataset with more detailed data at global and regional or country level, as well as all chapter figures, is available for purchase.

A 50-Year-Old Drug Might Find a New Life Treating Alzheimer’s

KFOR Oklahoma's News 4 12 October, 2021 - 03:41pm

On Monday, researchers showed that the drug bumetanide, normally used to manage fluid retention for conditions like hypertension, led to a reversal of Alzheimer’s symptoms in laboratory mice as well as human brain cells. And through a study of the health records of millions of patients, those same researchers found that people over 65 who took bumetanide regularly were 35–75 percent less likely to get diagnosed with Alzheimer’s.

The findings, published in Nature Aging, hinges around the gene APOE, which mediates fat metabolism in mammals but is also known to be a major risk factor for Alzheimer’s. Through an analysis of APOE gene records in Alzheimer’s patients, along with the data of 1,300 existing drugs, the researchers found that bumetanide might be associated with reversing the effects of altered APOE genes. The drug’s mechanisms for changing fluid retention in cells also plays a role in how neurons in the brain trigger electrical signaling, so it seems worth exploring.

It seems the researchers’ intuition about the drug was right. And Bumetanide’s potential to treat Alzheimer’s is bolstered by the fact that it is already FDA-approved, and has a safety record that stretches back for decades. “This is a drug with a well-established safety record, so it could reach patients much faster than typical drug development takes,” Gladstone Institute researcher and study coauthor Yadong Huang said in a statement.

That’s great news for getting a clinical trial started to truly test whether bumetanide can help combat Alzheimer’s. Huang and his team are already in advanced talks with other medical centers to get one started.

A European study has found an elevated risk of a life-threatening blood clot called venous thromboembolism (VTE) in COVID-19 patients who were not critically ill. The blood clot risk had previously been associated with severe COVID-19. The researchers tracked 2,292 patients who came to hospital emergency rooms with mild or moderate COVID-19 but without VTE.
