Taboos make it hard to discuss mortality in China
Posted by Derick Lee in categories: biotech/medical, government
Cultural inhibitions also impede the development of end-of-life care. Talking about death has long been taboo. People often feel that it is their filial duty to ensure that sick parents receive curative treatment, even when doctors advise that there is no chance of recovery and the treatment will be painful. Applications to build hospices are sometimes challenged by local residents who resent the presence of death on their doorsteps. Mr Li says neighbours’ objections have forced Songtang Hospice to move six times.
WHEN Li Songtang was 17, officials overseeing Mao’s chaotic Cultural Revolution sent him from Beijing to Inner Mongolia, a northern province where he became a “barefoot doctor”—a medical worker with rudimentary training. His patients included an academic whom the government had expelled in disgrace from the capital, and who had become terminally ill. The patient grew sicker and increasingly troubled by his political black mark. Unable to console him, Mr Li eventually lied that he had persuaded authorities to wipe the slate clean. The patient grabbed his arm with relief and gratitude, recalls Mr Li. “I can still feel it today.”
Mr Li’s experience of caring for the dying man eventually resulted in the hospice he runs in a three-storey building in Beijing’s outskirts. The facility is home to about 300 people, most of them elderly and with late-stage cancer (a patient there is pictured with a nurse). On a weekend the bright corridors are busy with volunteers who have come to chat with patients. Zhang Zhen’e, a smiley 76-year-old who shares her room with six other women, says she tries to stay cheerful because days spent worrying are “days lost”. A nearby ward for dying babies, painted green and decorated with mobiles, is less easy to visit. Eight children snooze there, asleep in mismatched wooden cots.

NASA’s priorities appear to be out of whack with what the public wants
Posted by Adriano Autino in categories: policy, space travel
A recent survey of 2,541 Americans by Pew Research Center shows that priorities felt by people are not the same intended by NASA. But: 1) Where the questions t…he most appropriate ones, in order to understand what people really think? 2) Is the NASA’s indicated priority, re-prioritization of human spaceflight by still focusing only on trained astronauts, the best strategic policy, considering the global civilization as the main stakeholder, or even just the US people stakeholder? 3) Which questions were missing, in your opinion, in this survey?
The Trump administration has vowed to make America great again in spaceflight, and the centerpiece of its space policy to date has been a re-prioritization of human spaceflight as central to NASA’s activities. As part of this initiative, the White House has sought to reduce funding for satellites to observe environmental changes on Earth and eliminate NASA’s office of education.
However, a new survey of 2,541 Americans by Pew Research Center, which aims to represent the views of US adults, finds that these views appear to be out of step with public priorities.

Two Quantum Computing Bills Are Coming to Congress
Posted by Genevieve Klien in categories: computing, government, quantum physics
Quantum computing has made it to the United States Congress. If this field of quantum information is the new space race, the US doesn’t want to fall behind.
After all, China has funded a National Laboratory for Quantum Information Sciences, set to open in 2020, and has launched a satellite meant to test long-distance quantum secure information. Two new bills, one of which is still a draft, are meant to establish the US as a leader in the field.
“Quantum computing is the next technological frontier that will change the world, and we cannot afford to fall behind,” said Senator Kamala Harris (D-California) in a statement passed to Gizmodo. “We must act now to address the challenges we face in the development of this technology—our future depends on it.”

Dynamics of Telomere Rejuvenation during Chemical Induction to Pluripotent Stem Cells
Posted by Alexander Rodionov in categories: biotech/medical, life extension
Chemically induced pluripotent stem cells (CiPSCs) may provide an alternative and attractive source for stem cell-based therapy. Sufficient telomere lengths are critical for unlimited self-renewal and genomic stability of pluripotent stem cells. Dynamics and mechanisms of telomere reprogramming of CiPSCs remain elusive. We show that CiPSCs acquire telomere lengthening with increasing passages after clonal formation. Both telomerase activity and recombination-based mechanisms are involved in the telomere elongation. Telomere lengths strongly indicate the degree of reprogramming, pluripotency, and differentiation capacity of CiPSCs. Nevertheless, telomere damage and shortening occur at a late stage of lengthy induction, limiting CiPSC formation. We find that histone crotonylation induced by crotonic acid can activate two-cell genes, including Zscan4; maintain telomeres; and promote CiPSC generation. Crotonylation decreases the abundance of heterochromatic H3K9me3 and HP1α at subtelomeres and Zscan4 loci. Taken together, telomere rejuvenation links to reprogramming and pluripotency of CiPSCs. Crotonylation facilitates telomere maintenance and enhances chemically induced reprogramming to pluripotency.
