Sugar starts corroding your teeth within seconds – here’s how to protect your pearly whites from decay

Bacteria living in your mouth get to work as soon as you take your first bite or sip of something sweet. Consuming your sugar more strategically can help keep cavities at bay.
Since the early 2000s, several studies have shown that asthma and allergy rates are significantly lower among people who grew up on a farm than among those who grew up in urban areas. (Shutterstock)

Growing up on a farm can prevent asthma and allergies

Children who grow up on farms are less likely to develop asthma or allergies as adults. The reason? Micro-organisms in the air.

Microbes can colonize space, produce drugs and create energy − researchers are simulating their inner workings to harness how

Using digital blueprints of the metabolism of microbes, scientists can simulate expensive and time-intensive experiments set in space, power plants and farm fields.

Tiny laboratories that fit in your hand can rapidly identify pathogens using electricity

Pathogens have distinct electrical charges, shapes and sizes. Measuring how quickly they move through an electric field can help researchers separate different species in a sample in minutes.
Current methods of identifying resistance mutations in microbes can miss other ways resistance can develop. koto_feja/iStock via Getty Images Plus

Fighting antibiotic resistance at the source – using machine learning to identify bacterial resistance genes and the drugs to block them

By analyzing the resistance genes and proteins of E. coli, researchers can optimize treatments to address both current and future antimicrobial resistance.

Found dead in the snow − how microbes can help pinpoint time of death for forensic investigations in frigid conditions

An accurate estimate of when someone died is a critical part of forensic investigations. In extremely cold conditions, molecular biology can provide critical information where the naked eye cannot.

Ancient viral genomes preserved in glaciers reveal the history of Earth’s climate – and how viruses adapt to climate change

From ice cores extracted from the Tibetan Plateau, scientists recovered the equivalent of 1,705 virus species. Reading their genomes tells the story of 41,000 years of climate change.
