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”. "

EXTRACT: "Perhaps it is Piller’s discovery that when it comes to war there is no such thing as innocence...."

EXTRACT: "I imagined America as the land of the free that gave voice to the forgotten. Where race, color, and creed do not matter and human rights are guarded with zeal. Where the ingathering of all cultures and people made it richer and human resources and talent knew no limits or constraints. Where opportunity awaits the able and generosity is extended to the needy. Where everyone is equal before the law and political differences are valued to make America better. Where sacrifices are willingly made to right the wrong morals and fortitude guide its leaders. Where caring about friends and allies is the hallmark of the nation and opposing oppression near and far is the emblem that distinguished America. This is the character of America. This is the soul of America. This is what made America great. The America that gave me a home. The America that fulfilled my dreams."

EXTRACT: "“The paintings which I propose to do will depict the struggles of a people to create a nation and their attempt to build a democracy” – this is how Jacob Lawrence described his project in 1954. Over sixty-five years later his proposal has, if anything, become only more urgent. Two days after this exhibition closes, Americans will vote in what is arguably the most significant election in a generation, an election that will measure our commitment to preserving that democracy, the struggle for which was Lawrence’s mighty theme."

EXTRACT: "There are also other ways our life stories can be passed down through generations, besides being inscribed in our DNA...... One 2014 study looked at epigenetic changes in mice. Mice love the sweet smell of cherries, so when a waft reaches their nose, a pleasure zone in the brain lights up, motivating them to scurry around and hunt out the treat.... The researchers decided to pair this smell with a mild electric shock, and the mice quickly learned to freeze in anticipation....... The study found this new memory was transmitted across the generations. The mice’s grandchildren were fearful of cherries, despite not having experienced the electric shocks themselves. The grandfather’s sperm DNA changed its shape, leaving a blueprint of the experience entwined in the genes."
Oct 1st 2020
EXTRACT: "As we Americans face the potential loss of a peaceful transition of power after the election and the possible end of democracy as we know it, we are reminded that discourse matters, that words matter and that the one who quotes poetry is a man who reads—and that matters."
Sep 25th 2020
EXTRACT: "We now know the potentially appalling long-term effects of suffering cruelty from others, including damage to both physical and mental health. The benefits of being compassionate towards oneself, rather than treating oneself cruelly, are also increasingly recognised..... And the idea that we must suffer to grow is questionable. Positive life events, such as falling in love, having children and achieving cherished goals can lead to growth..... Teaching through cruelty invites abuses of power and selfish sadism. Yet Buddhism offers an alternative - wrathful compassion. Here, we act from love to confront others to protect them from their greed, hatred and fear. Life can be cruel, truth can be cruel, but we can choose not to be."

EXTRACT: "Over his incredible career, David Attenborough has seen more of earth’s natural wonders than almost anyone. To hear him talk, with such clarity, about how bad things are getting is deeply moving. Scientists have recently demonstrated what would be needed to bend the curve on biodiversity loss. As Attenborough says in the final scene, “What happens next, is up to every one of us”. "

EXTRACTS: "The Anglo-Australian multinational company Rio Tinto – the largest iron ore mining company in the world – demolished two 46,000-year-old Aboriginal rock shelters in May.......The Dampier Archipelago of Western Australia is home to thousands of Aboriginal pictographs, and perhaps the oldest surviving rock art in the world. Indeed, Australia’s Indigenous art represents the longest uninterrupted tradition of art in the world – going back over 50,000 years......Aboriginal people represent the oldest continuous culture in the world...."
