Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

Random numbers are hugely important for modern computing.

They are used to encrypt credit card numbers and emails, to inject randomness into online gaming,

and to simulate super complex phenomena, like protein folding or nuclear fission.

But here's the dirty secret.

A lot of these so-called random numbers are not truly random.

They're actually what's known as pseudo-random numbers, generated by algorithms.

Think, for example, of generating random numbers by rolling dice.

If you know the number of dice, it's simple to figure out something about the realm of

possible random numbers,

thus putting probabilistic limits on the randomness.

But truly random numbers can be generated through quantum mechanical processes.

So researchers built a photonic chip.

That's a computer chip that uses photons instead of electrons.

The chip has two lasers. One shoots continuously,

the other pulses at regular intervals. And each time the two lasers meet, the interference

between the light beams is random, thanks to the rules of quantum mechanics. The chip then digitizes
