Lab cleanliness without broom and dust

Labs are normally cleaned by contracted company and their employees use different methods to remove dirt from the floor. The worst method I've seen so far is by using broom to sweep up the dirt. The smaller particles are prone to linger around the air and subsequently land onto benches, bottles, and opened solutions. If you are plating on the same day the floor is swept, you will realize that the plates will get contaminated with fungi the next day (if you are lucky). That's how bad sweeping in the lab is.
The best way to prevent unsettling dust and contaminating the air in the lab is to use electrostatic fabric that will attract dusts and which can be subsequently disposed of.

Minimum information about an experiment (MIAxE)

Minimum information about an experiment (MIAxE) is a publication standard to provide necessary information for other labs to be able to replicate the published experiment.

There are currently two well-known MIAxEs: Minimum information about qPCR experiment (MIAQE or MIQE) and minimum information about microarray experiment (MIAME).

I hope there will be other standards to facilitate other labs to validate published results in respected journals. There shouldn't be excuses as to why some experiments can't be replicated. Although biological system is unpredictable (sometimes) or variable (most of the time), these variabilities wouldn't be to huge to prevent reproducibility of results.
