Tiny Matters

A recent study looking at sleeping spiders left Sam and Deboki with a lot of questions, namely, “Do spiders dream? And why do we humans dream?” In this episode of Tiny Matters, you’ll hear all about dreaming and its connection to sleep, and learn what big questions the field is still trying to answer.

When you wash your dishes, take a shower, or flush a toilet you send a bunch of waste into your local sewer. But wastewater isn’t just filled with things like food scraps, soap, and feces—it also contains microbes, like viruses. During the pandemic, scientists realized how powerful a tool wastewater is for tracking many diseases, including COVID-19. Links to the Tiny Show & Tell stories here and here.

Regeneration is a hot topic in the sciences, and for good reason. We humans are not known for being great at regenerating, but if we could understand how other organisms do it so easily we might be able to heal a spinal cord injury or damaged organs and limbs. Or we could even slow the aging process and not suffer from diseases like Alzheimer’s. Links to the Tiny Show & Tell stories here and here. Episode transcripts at acs.org/tinymatters

Humans have been finding ways of preserving food for thousands of years—long before the invention of silica gel packs that absorb moisture or chemicals that keep away bacteria and mold. This week’s Tiny Matters is about the evolution of food preservation and the regulations that came about to keep us safe from the more dangerous food additives we came up with (ahem, arsenic candy).

On May 8, 1980, the World Health Organization declared that smallpox—a highly-deadly disease in humans—had been eradicated. Today it’s still the only one we’ve completely wiped out. So, how’d we do it? And why haven’t we done it for the many other diseases that plague us, like COVID-19? Links to the Tiny Show & Tell stories here and here.

On September 11, 2001, nearly 3,000 people died, many of whom were first responders. Today, World Trade Center first responders who are still alive are being diagnosed with illnesses like lung disease and cancer more often than the general population. Many scientists say the air pollution caused by the terrorist attack is to blame. Links to the Tiny Show & Tell stories here and here. Episode transcripts at acs.org/tinymatters

On December 5, 1952, the city of London was engulfed in a lethal black haze that killed thousands of people. This event, now known as the Great Smog, altered how London and much of the world viewed air pollution, and led to environmental policies that have no doubt saved many lives since then.

When it comes to human decomposition, scientists have a pretty good understanding of what happens shortly after you die. But what happens months or years later is mostly a mystery, and that makes it hard for law enforcement to figure out how a person died and, ultimately, provide answers to loved ones of the deceased. That’s where anthropological research facilities (a.k.a. body farms) come in. Links to the Tiny Show & Tell stories here and here. More on the MOVE bombing.
