Functional redundancy in mycobacteria
The tricarboxylic acid, or TCA, cycle is essential to carbon metabolism. Malate oxidation, a critical step of this cycle, is catalyzed by malate dehydrogenase or malate quinone oxidoreductase. These enzymes, Mdh and Mqo, respectively, tend to co-occur in a single bacterium, and one of them is usually primarily respons

Like it or not, China is different. The populous nation resides in an alternate universe where Covid-19 restrictions prevail and economic activity strains at the gates for gradual reopening.
But while global equity markets are suffering their worst first half-year start since 1970, Chinese stocks may be the one major market to offer uncorrelated positive returns in the second half of 2022.
Since mid-2021, Chinese markets have borne the brunt of selling well before the global bear market malaise in the first half of 2022. China has su

We most easily understand the passage of time measured in days, months and years, the units with which we routinely calibrate our lives. But the span of the cosmos is incomprehensibly greater. The “Cosmic Calendar” is a useful way of thinking about time. It imagines the span of the universe's existence as though it lasted a single year. The Big Bang, with which the universe began about

Changpeng Zhao does not like ambiguous words. Which is just as well: the crypto industry, in which he is a leading figure, is in turmoil and crying out for clarity.
The 45-year-old founder and chief executive of Binance, the world's biggest cryptocurrency exchange, meets the Observer in an upmarket London hotel after one of the most tumultuous weeks in the short history of digital money.

On May 30, Meta, Google and Twitter released their 2021 annual transparency reports, documenting their efforts to curb misinformation in Australia.
Despite their name, however, the reports offer a narrow view of the companies' strategies to combat misinformation.

They therefore highlight the need for effective legislation to regulate Australia's digital information ecosystem.
The transparency reports are published as part of the Digital Industry (DIGI) Group's voluntary code of practice
