The science of making sourdough bread

The transformation of dough into a loaf is chemistry in action. With a bit of physics and microbiology. And love…If bread is rising, sourdough is soaring. Along with pasta and toilet rolls, flour was among the first products to vanish from supermarket shelves and Covid-19 inspired a home-baking boom. While Google searches for “bread” tripled in the UK in the weeks after mid-March, those for “sourdough” rose sixfold. Sourdough differs from most bread in that it contains no baker’s yeast, relying ...

Study: Life might survive, and thrive, in a hydrogen world

As new and more powerful telescopes blink on in the next few years, astronomers will be able to aim the megascopes at nearby exoplanets, peering into their atmospheres to decipher their composition and to seek signs of extraterrestrial life. But imagine if, in our search, we did encounter alien organisms but failed to recognize them as actual life.That's a prospect that astronomers like Sara Seager hope to avoid. Seager, the Class of 1941 Professor of Planetary Science, Physics, and Aeronautics ...

Ask a Chemist: How does handwashing kill coronavirus?

A common recommendation from experts to help protect against coronavirus is to wash your hands often, but why? It turns out that each time you do it is an effective two-pronged attack.As Kate the Chemist explains, the virus has a weak outer membrane. By using the proper handwashing technique, you're actually breaking through that membrane and ripping the virus apart.Soap is an important part of the equation because of its two sides: the hydrophobic side (which grabs onto the virus), and the hydr...

Kate the Chemist: Water is a freak substance. Here’s why.

University of Texas professor and science entertainer Kate the Chemist joined Big Think to talk about water molecules and to answer two interesting and important questions: Why does boiling water make it safe to drink, and what happens to water when you boil or freeze it? According to Kate, when water is heated to a certain temperature (100°C/ 212°F) the hydrogen bonds break and it goes from a liquid to a gas state. Boiling for a minimum of 5 minutes kills any viruses and bacteria that were in t...

Molecules: The Elements and the Architecture of Everything

In 2009, Theodore Gray blew minds with his gorgeously photographed book, The Elements: A Visual Exploration of Every Known Atom in the Universe, which sold over a million copies. Five years later, Gray has created this book, which describes what happens when elements are snapped together to make molecules, and the result is a masterpiece (thanks in no small part to Nick Mann’s drool-inducing photographs). Gray organizes the book by categories of molecules — inorganic, organic, acids, bases, soap...

Lizards develop new chemical language to attract mates in predator-free environments

Scientists discovered that lizards developed novel chemical communication signals when relocated to tiny island groups with no predators.Male lizards began to rapidly produce a new chemical love elixir, not unlike cologne, to call on potential mates. With new technology we're increasingly able to detect and identify the chemicals that make up much of the language of non-human nature. Most of our understanding of animal communication has come through observations of auditory and visual symbol...

Chemists develop fast-degrading plastic for cleaner oceans

Cornell University chemists have developed a polymer with the strength of industrial-grade plastics but degrades quickly in sunlight. They hope the plastic will one day be used to make fishing nets that leave no environmental trace. Their research joins other programs and initiatives aimed at restoring our oceans. In popular imagination, the Great Pacific Garbage Patch is a concentration of trash adrift lazily on the ocean. It's an entire continent of tightly packed tires, Styrofoam, syringes, ...

Where citizen science meets the coronavirus—and how you can help

Since being founded in 2008, the crowdsourced protein-folding game, Foldit, has helped solve many novel problems. In recent months, the Foldit team has presented its community with problems relating to COVID-19. Foldit founder, David Baker, says over 20,000 different designs for potential COVID-19 antiviral proteins have been submitted. In 2008, University of Washington professor David Baker created the Foldit research project. As a protein research scientist he had spent a good portion of h...

Duke University uses vaporized hydrogen peroxide to clean N95 face masks for reuse

With shortages of N95 face masks persisting nationwide, healthcare facilities are scrambling to find ways to clean and treat the masks for reuse to protect doctors and nurses most at risk of exposure to COVID-19. Duke University thinks it has found a solution using vaporized hydrogen peroxide to decontaminate the masks. The process uses specialized equipment to vaporize hydrogen peroxide, which can then infuse all the layers of the mask to kill germs (including viruses) without degrading mask...

What is the world's foulest smell? It's called “U.S. Government Standard Bathroom Malodor”

Writing for The New York Times, Randall Monroe (creator of the xkcd comic) looks into the world's worst smell. It turns out that there is no universal agreement, but a strong contender for the title is something called U.S. Government Standard Bathroom Malodor, "a substance that was designed to mimic the scent of military field latrines, in order to test cleaning products." Another contender was accidentally cooked up one day by Derek Lowe, an industrial chemist: Dr. Lowe said that the worst thi...

Scientists make organs transparent so you can see inside

By manipulating light refraction in organ tissue, it can be made transparent.Coloring internal structures is as "simple" as slipping dyes between tissue cells.A new method paves the way for fully 3D imagery of mature human organs. As science dives deeper into the physiology of human organs, and in particular the human brain, it has become clear that viewing such organs in three dimensions and in microscopic detail is of critical importance if we're ever to understand how they work. Of course, o...

With Tony Fadell’s help, Advano is building battery components to power an electric future

Using scrap silicon as its feedstock, a New Orleans-based company called Advano has raised $18.5 million to manufacture battery components to enable more powerful, smaller, and longer lasting batteries. The technology was innovative enough to earn the Lousiana-based startup a place in Y Combinator’s famed accelerator and has now attracted the attention of Mitsui Kinzoku, which is investing in the company as a strategic partner, and Tony Fadell, the famous product designer known as ‘the fat...
