In this rare 1997 interview, a young Jeff Bezos explains the brilliant, mathematical logic behind the founding of Amazon.com. After seeing that web usage was growing at 2,300% a year, Bezos systematically made a list of 20 products to sell online. He chose books because there were over 3 million active titles in print—a volume of inventory that allowed him to build an online store that simply couldn’t exist in the physical world. Jeff Bezos is the founder and executive chairman of Amazon, and one of the most successful entrepreneurs in modern history. #Entrepreneurship #Success #Business #Startup #Mindset #JeffBezos #Amazon #TechHistory …

Scientists Can Now See DNA Folding at Near-Molecular Resolution
The finding could eventually enable the use of DNA packaging in cells for disease diagnosis and treatment.
In preserved cells, newly developed fluorescent probes allowed researchers to pinpoint individual dye molecules to within 3 nanometers, close to the width of the DNA double helix itself. The same molecules can also reveal how DNA is packaged and moves inside living cells, giving scientists a way to examine chromatin at resolutions that were previously difficult to achieve without killing the cells.
When the team tested the probes on wax-preserved bowel tissue from three cancer patients, they found another striking difference. DNA in the tumors appeared noticeably looser and more spread out than in healthy tissue immediately beside it. Other research has found that DNA progressively unpacks as cancer develops, raising the possibility that its degree of folding could eventually provide information about how advanced or aggressive a tumor is.
How AI plotted an interstellar journey to Alpha Centauri
A nonprofit organization called the Fermi Explorer Mission announced today that it intends to launch a spacecraft to our nearest star system by the end of 2029.
It’s a hugely ambitious mission—if all goes well, the spacecraft could take up to 80,000 years to arrive at Alpha Centauri, which is 4.4 light-years away. And the spacecraft will follow a novel trajectory discovered by an AI system developed by Physical Superintelligence (PSI), an AI physics research lab. PSI is launching today with $58 million in funding led by Breakthrough Energy, a climate-focused investment group founded by Microsoft cofounder Bill Gates.
