Text CB1A7
Whenever a global economic transformation takes place, a single city usually drives it forward. Ghent, in modern-day Belgium, was at the core of the burgeoning global wool trade in the 13th century. The first initial public offering took place in Amsterdam in 1602. London was the financial centre of the first wave of globalisation during the 19th century. Today the city is San Francisco.
California’s commercial capital has no serious rival in generative artificial intelligence (AI), a breakthrough technology that has caused a bull market in American stocks and which, many economists hope, will power a global productivity surge. Almost all big AI start-up companies are based in the Bay Area, which comprises the city of San Francisco and Silicon Valley (largely based in Santa Clara county, to the south). OpenAI is there, of course; so are Anthropic, Databricks and Scale AI. Tech giants, including Meta and Microsoft, are also spending big on AI in San Francisco. According to Brookings Metro, a think tank, last year San Francisco accounted for close to a tenth of generative AI job postings in America, more than any other city of the country. New York, with four times as many residents, was second.

Aspartame - is it a possible cause of cancer?
The sweetener aspartame, which is found in a variety of foods and fizzy drinks, is set to be officially classified as "possibly carcinogenic" to humans, reports claim.
The label frequently causes confusion as it gives no sense of whether the potential risk is big or miniscule.
Other "possibly carcinogenic" substances include aloe vera, diesel and pickled Asian vegetables.
The BBC understands the International Agency for Research on Cancer (IARC) will make an announcement on 14 July.

John is a hardworking man. He always gets up early to work and to do all the things he has to do. Mary, John's wife, helps him and she usually spends a lot of time at work with John. John works all the time.
John and Mary have three children who often complain that their parents work too much and seldom enjoy life. They say, "Dad, you and Mom should take a break from work and try to have some fun. You never relax."
John's answer is: "Sometimes I think of taking a vacation, but who will pay our bills?". Mary agrees with John and says that someday their children will understand the situation.
