 | Mixed cultures: art, science, and cheese
Cheese is an everyday artifact of microbial artistry. Discovered accidentally when someone stored milk in a stomach-canteen full of gut microbes, acids, and enzymes thousands of years ago, cheesemaking evolved as a way to use good bacteria to protect milk from the bad bacteria that can make us sick, before anyone knew that bacteria even existed. In our modern world, with antimicrobial hand sanitizer dispensers in every elevator lobby, cheeses and other microbe-rich foods lie at the heart of a post-Pasteurian debate over the positive impact of microbes on our health and happiness

 | A Remote That Shatters Glass
Giuseppe Longobardi, a researcher at IBM in Castellammare di Stabia, Italy, recently patented a device that would allow a disaster victim to press a button on a remote control and safely shatter a window several feet away, or engineers could install a sensor to the window that would make it break automatically in case of smoke or extreme heat

| Fossilized food stuck in Neandertal teeth indicates plant-rich diet
Ancient humans' lax dental hygiene has been a boon for researchers looking for clues about early diets. Traces of fossilized foodstuffs wedged between Neandertal teeth have revealed plentiful traces of grains and other plants, supporting the theory that these heavy-browed humans were not just meat-eaters

 | Engineering students wrap up latest Tanzanian humanitarian project, pass the tipping point
Students from Dartmouth's Thayer School of Engineering are working in Tanzania to help improve sanitation and energy technologies in local villages. This series chronicles work being done by the student-led group, known as Dartmouth Humanitarian Engineering (DHE) [formerly known as Humanitarian Engineering Leadership Projects (HELP)], to design "rocket stoves" in the village of Mwamgongo and top-light updraft design (TLUD) gasification stoves in the village of Kalinzi. The goal is to create a healthier, more energy-efficient cooking apparatus that these villagers will accept and use. DHE students are filing these dispatches from the field during their trip. This is their 21st blog and final post for Scientific American

98.6 Trades Metabolic Cost For Fungal Protection
A mathematical model finds that a temperature of about 98.6 F is high enough to ward off the majority of fungal infections, but still low enough to only require a manageable level of food intake. Steve Mirsky reports
