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 ...

The end of plastic? New plant-based bottles will degrade in a year

Carlsberg and Coca-Cola back pioneering project to make ‘all-plant’ drinks bottlesBeer and soft drinks could soon be sipped from “all-plant” bottles under new plans to turn sustainably grown crops into plastic in partnership with major beverage makers.A biochemicals company in the Netherlands hopes to kickstart investment in a pioneering project that hopes to make plastics from plant sugars rather than fossil fuels.

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...

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...

Coronavirus distancing may need to continue until 2022, say experts

Scientists say one-time lockdown will not bring pandemic under controlCoronavirus – latest updatesSee all our coronavirus coveragePhysical distancing measures may need to be in place intermittently until 2022, scientists have warned in an analysis that suggests there could be resurgences of Covid-19 for years to come.The paper, published in the journal Science, concludes that a one-time lockdown will not be sufficient to bring the pandemic under control and that secondary peaks could be larger t...

CO2-based vodka startup Air Co. fully redirects its tech to making hand sanitizer for donation

An NYC-based startup that developed technology that extracts carbon dioxide from the air and combines it with water to create vodka has redirected its entire production capacity towards producing hand sanitizer, every bottle of which will be donated through collaboration with NYC officials, and potentially to local restaurants who employ delivery personnel providing critical service as social distancing and isolation measures continue. Air Co. launched its vodka just last year, using a process i...

Can psychedelics help treat pain?

Pharmacology professor Richard J. Miller is hopeful for the resurgence in clinical studies of psychedelics.Ibogaine, used in France for decades, is making a comeback in potentially helping curb addiction and treat pain. Psychedelics were deemed illegal for political and not medical reasons, an error we are reinvestigating. None With all the hype regarding the potential for psychedelics to help treat anxiety and depression, with the potential to replace or coexist with SSRIs, there are yet more ...

Engineers developed a mathematical model of Ooblek

A favorite kitchen chemistry (and physics) experiment of kids (and adults), Ooblek is the weird result of mixing cornstarch with water. Now, MIT engineers have developed a mathematical model that can predict and simulate how the non-Newtonian fluid switches between liquid and solid depending on the pressure applied to it. From MIT News: Aside from predicting what the stuff might do in the hands of toddlers, the new model can be useful in predicting how oobleck and other solutions of ultrafi...
