US senators attack Facebook and ask them to release their own research into how their products affect users after revelations about the harm some its platforms cause to vulnerable groups including children. (1) Image
The company knew that its social media sites were harming teens and didn’t do anything about it. It is time to turn off their ads and algorithms... Facebook claim we control the ads we see but we don't. They do. (2)
And Facebook cant change their algorithms. FT report one woman who had miscarried twins was constantly followed by ads about parenting +maternity. She typed in miscarriage repeatedly to get the algorithm to change but it didn't. She was still bombarded. (3)
So FB continue to harm us + our children because ads are the engine of their profits. They barely remove trolls or harmful anti-vaxxers or suicide memes, + profit from harm to children. Governments must stop this now. All credit to the US Congress. (4) @carolecadwalla

A new UNICEF report unicef.org/reports/fed-to… shows that worldwide, two out of every three children between the ages of 6 months to two years are not getting the nutritious diets they need to grow well. They propose ten actions: (1)
Food system
1. Increase the availability and affordability of nutritious foods – including fruits, vegetables, eggs, fish, meat and fortified foods – by incentivizing their production, distribution and retailing. (2)
2. Implement national standards and legislation to protect young children from unhealthy processed and ultra-processed foods and beverages and harmful marketing practices targeting children and families. (3)

Lessons for Afghanistan (and Covid). In 1986 I visited Vietnam and met Dr Duang Quynh Hoa, paediatrician and former Minister of Health in the communist regime. She showed me a ward full of malnourished children and criticised her own government. (1) Image
I learned much abt the Vietnam war by reading the historian Stanley Karnow who concluded that the USA had lost the war before it began. They fought an ideological war, but lost to nationalists who simply wanted foreigners out. Many US supposed allies were VietCong spies.(2) Image
But Karnow reported the lessons gleaned from interviews with defeated US generals. How you need to know your enemies and allies. (3) Image

The £20 benefit cut next month will reduce incomes of claimants less than 25years by 18% and >25 by 15%. Add in the effect of 2.5% inflation. Food bank use is up by one third in a year with one million parcels being given to children (1)
Destitution rates ("going without the essentials we all need to eat, stay warm and dry, and keep clean") have more than doubled since 2019 to 1 in 67 households...with rates as high as 1 in 17 HHs in the North West. (2)
We may expect to see 4-5 million people suffering periods of destitution this winter based on Joseph Rowntree figures from 2019, with unprecedented levels of hunger and food poverty. (3)

Climate change dwarfs the pandemic threat. The influence of summits and conference of the parties (COPs) over the past 30 years shows no effect on carbon emissions. (1)
We are in deep trouble: increases in extreme weather events, floods, droughts, wildfires, sea-level rise, food insecurity. And now scary signs of Gulf Stream collapse. (2) theguardian.com/us-news/2021/a…
Each year we publish the Lancet Countdown report describing 41 indicators which track the connections between public health and climate change. (3) lancetcountdown.org

I've heard three serious examples of misinformation on BBC programmes in the past 24 hours from Professor Robert Dingwall of JCVI, Lord Sumption and Sir Charles Walker MP. (1)
Dingwall, social science private consultant, who sits on JCVI (why?), was asked about Long Covid. He said the evidence was just 'anecdotal', the numbers of cases causally related to Covid was 'very small' and symptoms were due to people's 'minds' and 'stress'. He is wrong.(2)
Lord Sumption said deaths from Covid outside highly vulnerable groups is very small, 'in the hundreds'. Prof Spiegelhalter has since said he is wrong. (In India 2.2 million people are estimated to have died from Covid). Sumption should not be invited onto BBC to mislead.(3)

I don't mind public criticism but I do object to being misrepresented, in a major paper like @thesundaytimes without being consulted. Their leader writer Dominic Lawson has taken a pop at me so let me correct his accusations. (1)
He says I am not 'an epidemiologist', unlike Chris Whitty. He might have checked my publication record iris.ucl.ac.uk/iris/browse/pr… I would guess 80% of my 403 research papers are 'epidemiological', including numerous population trials.(2)
He takes a 2019 twitter quote from me about being "to the left of Jeremy Corbyn on economics and environmental issues." If you look at the context you'll see I was actually defending @campbellclaret from being expelled from the Labour party. (3)
