13 days, make skin cells 30 years younger and restore their ability to produce collagen | Global scientific news
? Regenerative medicine? 13 days, make the skin 30 years younger. In 2007, Shinya Yamanaka first used cell reprogramming technology to transform normal cells with specific functions into pluripotent stem cells (iPSC), and won the Nobel Prize for this, but normal cells lose their specific function in the process. Recently, a study published in eLife builds on this work by stopping partial reprogramming during stem cell redifferentiation, preserving the specific function of skin cells and "rejuvenating" skin cells.

EC: European Energy Union goals make good progress
(1) the overall trend. 1 the EU as a whole continues to make good progress in achieving the goals of the Energy Alliance, especially the energy and climate targets for 2020. In 2015, EU greenhouse gas emissions were 22% lower than in 1990, and emissions from industries covered by the European Energy Union's carbon emissions trading system (ETS) continued to decline. Based on 2014 data, EU renewable energy accounts for 16 per cent of total energy consumption. (2) the European Union has successfully decoupled its economic growth from greenhouse gas emissions. Between 1990 and 2015, EU gross domestic product (GDP) grew by 50 per cent, while emissions decreased by 22 per cent. According to the current trend forecast, the trend of decoupling between economic growth and greenhouse gas emissions will continue. (3) the EU has significantly reduced the intensity of greenhouse gas emissions. The European Union is currently one of the most economically efficient economies in greenhouse gas emissions and has become the most economically efficient country in the Group of 20 leading economies by setting climate and energy targets for 2030.

WRI: eight policy opportunities to support climate resilience
(1) increase the incentive for pre-disaster resilience. The Federal Emergency Management Agency (FEMA) has begun to develop a new "disaster deductible" (disaster deductible) policy, which requires states to pay deductible fees before receiving federal disaster assistance. States can reduce their deductibles by implementing pre-disaster resilience measures. To make further progress, the federal government can: 1 provide additional pre-disaster assistance by increasing funding for FEMA pre-disaster mitigation projects; and 2 promote "disaster deductibles" from concept to comprehensive policies to encourage states to implement pre-disaster measures.
