Good news derailed UK Prime Minister Theresa May’s manifesto launch. She might not have seen it that way — it is rare for any party to abandon a manifesto pledge just four days after its announcement and U-turns of this nature are embarrassing for a sitting prime minister with a reputation as a stickler for detail. But none the less, the social care debacle is the result of some exceptionally good news.
A protein has been found to have a previously unknown role in the ageing of cells, according to an early study by Queen Mary University of London (QMUL). The researchers hope that the findings could one day lead to new treatments for ageing and early cancer.
Scientists from the Florida campus of The Scripps Research Institute (TSRI) have shown how aging cripples the production of new immune cells, decreasing the immune system's response to vaccines and putting the elderly at risk of infection. The study goes on to show that antioxidants in the diet slow this damaging process.
As we age, the physical make up of our brains changes. This includes changes in neural processing in grey matter, but also in the deterioration of structural connections in the brain, which allow communication between distinct brain regions, so the brain is able to work as a well-wired network system.
