British scientists have identified a gene that doubles the risk of dying from Covid-19, opening up possibilities for targeted medicine and providing new insights into why some people are more susceptible to the disease than others. Researchers at Oxford University found that 60% of people with South Asian ancestry carry the high-risk gene. The discovery partly explains the high number of deaths seen in some British communities, and the effect of Covid in the Indian subcontinent. The scientists found that the increased risk is not because of a difference in genetic coding of the proteins, but because of differences in the DNA that makes a kind of ‘switch’ to turn a gene on. That genetic signal is likely to affect cells in the lung. The study shows that the way in which the lung responds to the infection is critical. This is important because most treatments have focused on changing the way in which the immune system reacts to the virus.

Kasia Wappa lives by Poland’s national park where a humanitarian crisis is unfolding on a scale not seen since World War 2. She is part of a network trying to save emaciated Middle Eastern immigrants who have been emerging from the wilderness since September. Most had spent days without food or water and were suffering from hypothermia and exhaustion. Some were sick from drinking swamp water. Kasia began by donating warm clothes, and now helps rescue parties retrieve lost and starving people from the woods. But the flow of migrants has increased, and she warns that many probably never make it. Ten deaths have been confirmed, and they have rescued many on the verge of dying. The Polish government has built a three-kilometre deep security cordon the length of its Belarus border to curb illegal immigration. All reporters are banned, creating a media blackout to hide the scale of the crisis. Rescuers now behave like insurgents, operating at night and evading police patrols.

FELM, a Finnish Christian missionary group, has cut ties with Palestinian children's rights NGO Defence for Children International-Palestine. Mr Stefansson, the charity's executive director, said they had concerns about possible banking sanctions of DCIP who are one of six Palestinian groups accused by Israel of channelling donor aid to militants and labelled as a terrorist organisation. The six accused groups have close ties to the Popular Front for the Liberation of Palestine, which carries out deadly attacks on Israelis and is on US and EU terrorism blacklists. DCIP rejects the charge and says it has asked FELM to reconsider cutting funds. Steffansson said it is impossible to maintain ties with the group as, ‘It could have impacted the work we do in 30 countries through banking services.’ DCIP relies on European aid to fund its advocacy and rights monitoring work in the Israeli-occupied West Bank and Gaza.

Txai Suruí is a climate activist who is part of an indigenous community in the Amazon rainforest. She spoke to world leaders at COP26 about the direct impacts of climate change that her tribe is already experiencing. But after the speech she was publicly criticised by President Bolsanaro for ‘attacking Brazil’. This prompted many people to send her abuse on social media. When she spoke to a BBC reporter, she said, ‘I think I said the right words because they attacked me.’ Brazil hosts the two most important and diverse tropical forests globally. Almost 20% of the Amazon forest has been cut down in recent decades. This deforestation must stop before it becomes a savanna. Between 2004 and 2012, Brazil successfully controlled deforestation by 80%, by reducing illegal foresting, creating protected areas and restricting soya and cattle expansion. This resulted in increased food production by large farming complexes and strengthened smallholder farming. See
