Using Sound To Control Enzymatic Reactions

Unhackneyed compartmentalization generated by audible sound allows the enzyme reactions to be controlled spatiotemporally.

Spatiotemporal regulation of multistep enzyme reactions through compartmentalization is essential in studies that mimic natural systems such as cells and organelles. Until now, scientists have used liposomes, vesicles, or polymersomes to physically separate the different enzymes in compartments, which function as ‘artificial organelles’. But now, a team of researchers led by Director KIM Kimoon at the Center for Self-assembly and Complexity within the Institute for Basic Science in Pohang, South Korea successfully demonstrated the same spatiotemporal regulation of chemical reactions by only using audible sound, which is completely different from the previous methods mentioned above.

Although sound has been widely used in physics, materials science, and other fields, it has rarely been used in chemistry. In particular, audible sound (in the range of 20–20,000 Hz) has not been used in chemical reactions so far because of its low energy. However, for the first time, the same group from the IBS had previously successfully demonstrated the spatiotemporal regulation of chemical reactions through a selective dissolution of atmospheric gases via standing waves generated by audible sound back in 2020.

Tesla releases its 2021 Impact Report, shows strides toward full sustainability

Tesla has released its 2021 Impact Report, and it revealed that the company is making huge strides in its efforts to help accelerate the world’s shift to sustainable energy.

From the people it employs to its supply chain and products, Tesla is transforming itself into an entity that is cleaner, more efficient, and more responsible than ever before.

Tesla’s website focused on four notable portions of its 2021 Impact Report, namely the company’s people, environment, supply chain, and products. In each of these topics, Tesla highlighted the steps it took to better itself while setting a standard for the automotive industry as a whole.

Why a bipartisan embrace of crypto might never touch Bitcoin

Crypto’s biggest skeptics see plenty of reasons to criticize the industry, but generally at the heart of most complaints is a belief that crypto is contributing very little to society while burning massive amounts of energy.

While crypto’s believers could squabble over the former point until they’re blue in the face, the latter is a little harder to deny. Bitcoin uses an estimated 204.50 terawatt-hours (TWh) of electricity per year at current rates according to the oft-cited tracker built by Digiconomist, this number is equal to the power consumption of Thailand. Meanwhile Ethereum’s energy footprint is half the size but still comparable to the power consumption of Kazakhstan. In 2018 the United States reported its total consumption of electricity as 4,222.5 TWh.

For some legislators, those numbers are hard to swallow. This week, the New York State Assembly passed a bill that had team crypto up in arms. The bill blocks the formation of crypto mining firms in the state that rely on non-renewable power. It notably doesn’t apply to existing facilities. A corresponding bill is currently making its way through the Democrat-controlled state senate. everyone, and welcome back to Chain Reaction.

Jeff Bezos Loses $13 Billion in Hours as Amazon Shares Slump

Amazon slid 14%, pulling Nasdaq 100 to lowest since March 2021.

Jeff Bezos saw $20.5 billion of his fortune melt away after Amazon.com Inc.’s results left investors disappointed, helping fuel the worst month for technology stocks in years.

Shares of the e-commerce company were down 14% on Friday after it reported a quarterly loss and the slowest sales growth since 2001. Bezos’s net worth fell to $148.4 billion, according to the Bloomberg Billionaires Index, from a peak this year of more than $210 billion.
