Staying active throughout adulthood is linked to lower healthcare costs in later life – new research
Mar 14th 2021
EXTRACT: "Exercise is good for your health at every age – and you can reap the benefits no matter how late in life you start. But our latest research has shown another benefit of being physically active throughout life. We found that in the US, people who were more physically active as teenagers and throughout adulthood had lower healthcare costs."

EXTRACT: "Although around one in 14 people over 65 have Alzheimer’s disease, there’s still no cure, and no way to prevent the disease from progressing. But a recent study may bring us one step closer to preventing Alzheimer’s. The trial, which was conducted on animals, has found a specific molecule can prevent the buildup of a toxic protein known to cause Alzheimer’s in the brain."

EXTRACT: "The art historian George Kubler observed that scholars in the humanities “pretend to despise measurement because of its ‘scientific’ nature.” As if to illustrate his point Robert Storr, former dean of Yale’s School of Art, declared that artistic success is “completely unquantifiable.” In fact, however, artistic success can be quantified, in several ways. One of these is based on the analysis of texts produced by art scholars, and this measure can give us a systematic understanding of how changes in recent art have produced changes in the canon of art history."
I was the Australian doctor on the WHO’s COVID-19 mission to China. Here’s what we found about the origins of the coronavirus

EXTRACT: "The most politically sensitive option we looked at was the virus escaping from a laboratory. We concluded this was extremely unlikely."

EXTRACT: ".... these men were completely unaware that they had put their lives in the hands of doctors who not only had no intention of healing them but were committed to observing them until the final autopsy – since it was believed that an autopsy alone could scientifically confirm the study’s findings. As one researcher wrote in a 1933 letter to a colleague, “As I see, we have no further interest in these patients until they die.” ...... The unquestionable ethical failure of Tuskegee is one with which we must grapple, and of which we must never lose sight, lest we allow such moral disasters to repeat themselves. "

EXTRACT: "In 2010 Carlos Rodriguez, the president of Buenos Aires' Universidad del CEMA, created the world's first - and only - Center for Creativity Economics. During the next ten years, the CCE presented a number of short courses and seminars. But the most important of its events was an annual lecture by an Argentine artist, who was given a Creative Career Award."

EXTRACT: "It’s not hard to see why. Although AI systems outperform humans in tasks that are often associated with a “high level of intelligence” (playing chess, Go, or Jeopardy), they are nowhere close to excelling at tasks that humans can master with little to no training (such as understanding jokes). What we call “common sense” is actually a massive base of tacit knowledge – the cumulative effect of experiencing the world and learning about it since childhood. Coding common-sense knowledge and feeding it into AI systems is an unresolved challenge. Although AI will continue to solve some difficult problems, it is a long way from performing many tasks that children undertake as a matter of course."

EXTRACT: "When it comes to being fit and healthy, we’re often reminded to aim to walk 10,000 steps per day. This can be a frustrating target to achieve, especially when we’re busy with work and other commitments. Most of us know by now that 10,000 steps is recommended everywhere as a target to achieve – and yet where did this number actually come from?"

EXTRACT: "This so-called elite supposedly conspires to monopolise academic employment and research grants. Its alleged objective is to deny divine authority, and the ultimate beneficiary and prime mover is Satan.Such beliefs derive from the doctrine of biblical infallibility, long accepted as integral to the faith of numerous evangelical and Baptist churches throughout the world, including the Free Church of Scotland. But I would argue that the present-day creationist movement is a fully fledged conspiracy theory. It meets all the criteria, offering a complete parallel universe with its own organisations and rules of evidence, and claims that the scientific establishment promoting evolution is an arrogant and morally corrupt elite."

EXTRACT: "Ageing is so far known to be caused by nine biological mechanisms, sometimes called the “hallmarks of ageing”. In order to prevent ageing in our tissues, cells, and molecules, we need to be able to slow or prevent these hallmarks of ageing from taking place. While there are numerous treatments currently being investigated, two approaches currently show the most promise in slowing the development of age-related disease. .... One area researchers are investigating is looking at whether any medicines already exist which could tackle ageing. This method is advantageous in that billions of pounds have already been spent on testing the safety and efficacy of these drugs and they are already in routine clinical use in humans. Two in particular are promising candidates."
Cognitive decline due to ageing can be reversed in mice – here’s what the new study means for humans
Jan 23rd 2021
EXTRACT: "The ageing global population is the greatest challenge faced by 21st-century healthcare systems. Even COVID-19 is, in a sense, a disease of ageing. The risk of death from the virus roughly doubles for every nine years of life, a pattern that is almost identical to a host of other illnesses. But why are old people vulnerable to so many different things? It turns out that a major hallmark of the ageing process in many mammals is inflammation. By that, I don’t mean intense local response we typically associate with an infected wound, but a low grade, grinding, inflammatory background noise that grows louder the longer we live. This “inflammaging” has been shown to contribute to the development of atherosclerosis (the buildup of fat in arteries), diabetes, high blood pressure , frailty, cancer and cognitive decline."

EXTRACT: "Anthropos is Greek for human.... The term is used to convey how, for the first time in history, the Earth is being transformed by one species – homo sapiens. ...... The idea of the Anthropocene can seem overwhelming and can generate anxiety and fear. It can be hard to see past notions of imminent apocalypse or technological salvation. Both, in a sense, are equally paralysing – requiring us to do nothing. .. I consider the Anthropocene as an invitation to think differently about human relationships with nature and other species. Evidence suggests this reorientation is already happening and there are grounds for optimism."

EXTRACT: "During the second world war, Nazi Germany banned all listening to foreign radio stations. Germans who overlooked their duty to ignore foreign broadcasts faced penalties ranging from imprisonment to execution. The British government imposed no comparable ban which would have been incompatible with the principles for which it had gone to war. That’s not to say, though, that it wasn’t alarmed by the popularity of German stations. Most effective among the Nazis broadcasting to the UK was William Joyce. This Irish-American fascist, known in Britain as “Lord Haw-Haw”, won a large audience during the “phoney war” in 1939 and early 1940, with his trademark call sign delivered in his unmistakable accent: 'Jairmany calling, Jairmany calling'. "

EXTRACTS: "The revelation of Trump’s hour-long recorded call with Brad Raffensperger, Georgia’s Secretary of State, over this past weekend crossed a new line – a line that not only set a high-water mark of moral reprehensibility, but a legal line as well, specifically in his pressuring Raffensperger to 'find the 11,780 votes' that would hand Trump the state and his veiled threat (' it’s going to be very costly…') if Raffensperger failed to comply. ........ Raffensperger – who has been forced to endure intense pressure, intimidation and threats – has proven himself to be a man of integrity and principle."

EXTRACT: "A final, perhaps more sinister, possibility is that Johnson knows exactly what he is doing. His political style evokes a unique blend of dishevelled buffoon and privileged Etonian. He is someone who likes to bring good news and doesn’t take life too seriously. Making tough, controversial decisions threatens this persona and so hiding in the shadows until his hand is forced helps him to reconcile his identity threat."

EXTRACT: "The resultant loss of land, the growing impoverishment of its citizens, and the hostile actions of Israeli occupation forces and settlers have forced many Bethlehemites to leave their beloved city and homeland. Given these accumulated violations of human rights and their impact on Christians and Muslims, alike, one might expect Christians in the West to speak out in defense of these residents of the little town they celebrate each year. That, sadly, is not to be – most especially (and I might add ironically) among powerful Christian conservative groups in the US which, after all, claim to be the defenders of their co-religionists world-wide."

EXTRACT: "Worldwide, people donate hundreds of billions of dollars to charity. In the United States alone, charitable donations amounted to about $450 billion last year. As 2020 draws to a close, perhaps you or members of your family are considering giving to charity. But there are, literally, millions of charities. Which should you choose?"

EXTRACT: " The Museum of Modern Art is currently presenting Félix Fénéon: The Anarchist and the Avant-Garde – From Signac to Matisse and Beyond, examining the immense influence of this art critic, editor, publisher, collector and anarchist............A crucial feature of anarchism is the emphasis on the individual as the fundamental building block, the essential point of departure for any human association whatever. The individual was characterized by Grave in 1899 as a social creature who should be “left free to attach himself according to his tendencies, his affinities, free to seek out those with him whom his liberty and aptitudes can agree.” "

EXTRACT: "As the pandemic raged in April, churchgoers in Ohio defied warnings not to congregate. Some argued that their religion conferred them immunity from COVID-19. In one memorable CNN clip, a woman insisted she would not catch the virus because she was “covered in Jesus’ blood”. "
