Researchers detail an artificial molecular machine that moves a substrate between different activating sites to achieve different product outcomes from chemical synthesis. This molecular robot can be programmed to stereoselectively produce, in a sequential one-pot operation, an excess of any one of four possible diastereoisomers from the addition of a thiol and an alkene to …
The Life Extension Advocacy Foundation: LEAF has an update of SENS research progress against the 7 kinds of aging damage. Senescent Cells Senescent cell clearance has been all the rage for the past two years or so; Lifespan.io has hosted the MMTP project, which focused on testing senolytics in mice, and this was later followed …
The US National Nuclear Security Administration (NNSA) has submitted to the US Nuclear Regulatory Commission a preliminary report on a new uranium fuel that will enable the conversion of six US research reactors from highly enriched uranium to low-enriched uranium. The preliminary report on uranium-molybdenum (U-Mo) monolithic fuel contains data about the performance of the …
The MIT Camera Culture group present a new approach to time-of-flight imaging that increases its depth resolution 1,000-fold. That’s the type of resolution that could make self-driving cars practical. The new approach could also enable accurate distance measurements through fog, which has proven to be a major obstacle to the development of self-driving cars. At …
China will extend a tax rebate on the purchase of new-energy vehicles (NEV) until the end of 2020, in a continuation of policy support for the shift away from the internal combustion engine. The Ministry of Finance said in a statement on Wednesday the tax exemption, which was set to expire at the end of …
The Centre for Economics and Business Research (CEBR) forecasts that China’s economy will pass the USA in exchange rate terms by 2030. The report by the Centre for Economics and Business Research in London sees India leapfrogging the U.K. and France next year to become the world’s fifth-biggest economy in dollar terms. It will advance …
If schedules hold, Florida’s Space Coast could see up to three dozen launches in 2018 thanks to government and commercial payload missions that will fly on SpaceX and United Launch Alliance rockets. Spacex should have about 30 of the launches. SpaceX CEO Elon Musk recently announced on Twitter that the Spacex Heavy will launch his …
Data collected by NASA’s Juno spacecraft during its first pass over Jupiter’s Great Red Spot in July 2017 indicate that this iconic feature penetrates well below the clouds. Other revelations from the mission include that Jupiter has two previously uncharted radiation zones. The findings were announced Monday at the annual American Geophysical Union meeting in …
Crispr/Cas9 is a riboprotein complex composed of a short strand of RNA and an efficient DNA-cutting enzyme. Crispr/Cas9 sometimes cuts in the wrong places. And it has no off-switch. Epigenetic Editing Other proteins—like ones that activate gene expression—can be combined with a crippled Cas9, letting them toggle genes on and off (sometimes with light or …
A Stanford-led group of leading AI thinkers called the AI100 has launched an index that will provide a comprehensive baseline on the state of artificial intelligence and measure technological progress in the same way the gross domestic product and the S&P 500 index track the U.S. economy and the broader stock market. They have produced …
IBM, Dwave Systems, Google, Rigetti, Intel and others are computing to develop faster quantum computing systems. In November, 2017, IBM announced a 50 qubit prototype quantum computer chip. IBM, Google and Rigetti are working on approximate gate model systems. Rigetti has a 19 qubit chip. The time to scale up and develop new chips with …
