DESPITE CLEANING, SCHOOL DESKS ARE SUPER GROSS

It’s no exaggeration to say that bacteria are everywhere, but one place is especially bad. Work done by Dr. Sarah Kwan of The Peccia Environmental Biotechnology Laboratory at Yale University found an overwhelming number of microbes in schools — or, more specifically, on school desks. Though germs in schools are to be expected, the study found that even after a deep cleaning, the germs on school desks came back in full force within just a few days.


How Germs Thrive on School Desks

Looking at the microbial communities that grow on students’ desks, a team of Yale researchers found that the bacteria and fungi overwhelmingly came from the children sitting at the desks. They also found that, even after a desk cleaning, the microbes were back in full force within a few days.

Environmental engineers Jordan Peccia and Drew Gentner are finding new ways to study the air we breathe - both indoors and out.


How Do Indoor Microbiomes Affect Human Health?

The National Academies of Sciences, Engineering and Medicine are conducting a study of microbial communities inside buildings and how they affect human health. The report is expected to be published later this year.


Beneficial Microbes in Building Air

Two Yale University researchers—Jordan Peccia and Sarah E. Kwan—make the case that we may want to start designing to intentionally allow exposure to certain microbes in buildings, including our homes.


Why architects should let the microbes in

Architectural design is often concerned with energy efficiency or aesthetics, not microbial exposure. But, in a new article environmental engineers make a case for assessing the benefits of having these unseen organisms in our homes. Maybe, they say, instead of pushing all of them out, we should let the right ones in.


Invite good bacteria into home: scientists

A squeaky clean home, free of bacteria and fungi, may not be as healthy as you think, say US experts.


Letting the right microbes into your house is healthy

Instead of making our living environments as sterile as possible, we should be designing our homes for us and our microbial roommates.



New study finds that designers are neglecting beneficial microbes

Architectural design too concerned with energy efficiency and aesthetics, while failing to ensure easy access for microbes, a new study suggests.


Fill Your House With Microbes and Live With an Animal, Say Yale Researchers

"To Peccia and Kwan, one of the best delivery mechanisms for germs is — you guessed it — pets, since cohabitating with an animal increases the “bacterial and fungal diversity in house dust” in a home".
