China and South Korea used smartphone apps to monitor people with the disease. But Americans have different views of privacy and data collection.
Coronavirus’s economic danger is exponentially greater than its health risks to the public. If the virus does directly affect your life, it is most likely to be through stopping you going to work, forcing your employer to make you redundant, or bankrupting your business.
The trillions of dollars wiped from financial markets this week will be just the beginning, if our governments do not step in. And if President Trump continues to stumble in his handling of the situation, it may well affect his chances of re-election. Joe Biden in particular has identified Covid-19 as a weakness for Trump, promising “steady, reassuring” leadership during America’s hour of need.
Prolonged expression of the CRISPR-Cas9 nuclease and gRNA from viral vectors may cause off-target mutagenesis and immunogenicity. Thus, a transient delivery system is needed for therapeutic genome editing applications. Here, we develop an extracellular nanovesicle-based ribonucleoprotein delivery system named NanoMEDIC by utilizing two distinct homing mechanisms. Chemical induced dimerization recruits Cas9 protein into extracellular nanovesicles, and then a viral RNA packaging signal and two self-cleaving riboswitches tether and release sgRNA into nanovesicles. We demonstrate efficient genome editing in various hard-to-transfect cell types, including human induced pluripotent stem (iPS) cells, neurons, and myoblasts. NanoMEDIC also achieves over 90% exon skipping efficiencies in skeletal muscle cells derived from Duchenne muscular dystrophy (DMD) patient iPS cells. Finally, single intramuscular injection of NanoMEDIC induces permanent genomic exon skipping in a luciferase reporter mouse and in mdx mice, indicating its utility for in vivo genome editing therapy of DMD and beyond.

There’s a new breakthrough that might just be the secret ingredient to commercialize “the holy grail of energy,” nuclear fusion.
Two other international teams are planning Mars launches in July. NASA plans to deploy a rover named Perseverance, and the United Arab Emirates will send a probe called Hope. The European and Russian space agencies were planning to send a probe to Mars this year, but announced on Thursday that the launch will be delayed by two years so they can finish important tests, and partly because of the coronavirus pandemic.
China’s first journey to Mars is one of the most anticipated space missions of the year. But with parts of the country in some form of lockdown because of the coronavirus, the mission teams have had to find creative ways to continue their work.
Researchers involved in the mission remain tight-lipped about its key aspects, but several reports from Chinese state media say that the outbreak will not affect the July launch — the only window for another two years.

Scientists who study the biology of Aging agreed that we would someday be able to slow down the aging process substantially.
Dr. Aubrey de Grey, Chief Science Officer at SENS Research Foundation and VP of New Technology Discovery at AgeX Therapeutics believes that the critical biomedical technology required to eliminate aging derived debilitation and death is now within reach.
In his book “Ending Aging” he and his research assistant Michael Rae described the details of this biotechnology. They explained that the Aging of the human body, just like the Aging of manmade machines, results from an accumulation of various types of damage. As with manmade machines, this damage can periodically be repaired, leading to the indefinite extension of the machines fully functional lifetime just as is routinely done with classic cars.
Researchers from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute; AEI) in Hannover together with international colleagues have published their second Open Gravitational-wave Catalog (2-OGC). They used improved search methods to dig deeper into publicly available data from LIGO’s and Virgo’s first and second observation runs. Apart from confirming the ten known binary black hole mergers and one binary neutron star merger, they also identify four promising black hole merger candidates, which were missed by initial LIGO/Virgo analyses. These results demonstrate the value of searches in public LIGO/Virgo data by research groups independent of the LIGO/Virgo collaborations. The research team also makes available its complete catalogue in addition to detailed analysis of more than a dozen possible binary black hole mergers.
“We incorporate cutting edge methods,” says Alexander Nitz, a staff scientist at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) in Hannover, who led the international research team. “Our improvements enable discovering fainter binary black hole mergers: the four additional signals show that this works!”
The results were published in The Astrophysical Journal today.
Ren Zhiqiang appears to be the latest government critic silenced by the Communist Party as it cracks down on dissent over the epidemic.
