The travelling salesman problem is a famous network optimisation problem that hasn't been improved upon in forty-four years, until now! Researchers Nathan Klein, Anna Karlin and Shayan Ovies Gharan at the University of Washington have created a new algorithm that improves on the general traveling salesman problem, by 0.2 billionth of a trillionth of a trillionth of a percent!

COVID-19 Vaccine Predictions

#231
The Center For Global Development have published research on predicting the rollout timelines of a COVID-19 vaccine. The predictions show a 50% chance of a vaccine by April 2021, rising to 100% by September 2023. The paper also estimates that a total of just under 24 billion doses will be needed globally, distributed between health workers (115m), 65+ people(1.6bn), at risk people (4.2bn), and the rest of the population (18bn).

Podcast of the Week: Artificial Intelligence with Lex Fridman - Stephen Wolfram

#221
I recently discovered the Artificial Intelligence with Lex Fridman podcast via Find That Pod. It's like the Tim Ferris podcast but very heavy on the science detail. Lex interviews a range of the world's leading scientists, theorists and technologists and digs deep into their topics. I enjoyed his interview with Stephen Wolfram. Most of the podcast episodes leave me with questions and the want to learn more, which is great!

COVID-19 Detection Through Speech

#220
Researchers MIT's Lincoln Laboratory have identified a way to recognise COVID-19 in asymptomatic people by analysing their speech patterns. The theory that the constriction of muscles caused by a COVID-19 infection could affect speech in otherwise asymptomatic people was put to the test by analysing speech from video interviews of asymptomatic celebrities before and after their postive diagnosis.
