An AI system identified a potential new drug in just 46 days (1 minute read)

A team from an AI pharma startup used an artificial intelligence system to examine previous research and patents for molecules known to work against a drug target. It came up with 30,000 designs for potential molecules within 21 days. Six of these molecules were synthesized in the lab and tested in cells, with the most promising molecule tested in mice. The whole process took 46 days. Getting a drug to market is expensive and time consuming. Drug companies have invested a lot in using AI to expedite the process.

Google Interview Problems: Ratio Finder (26 minute read)

This article is part of a series that discusses interview questions that have been asked at Google in the past, with the other articles discussing dynamic programming, matrix exponentiation, and query synonymity. Interview questions should be designed so employers can make a decision of whether a candidate is worth hiring. The Ratio Finder question was chosen because it was a little easier, but still showed the candidates' strengths and weaknesses. Candidates were asked to design a system to convert between two units, for example, hands to light-years. While many will start thinking of a solution to the problem, strong candidates would think about how the program could fail. The success of the candidates depends on their ability to plan forward for potential problems, how complete the solution is, and what ideas they have to improve the code design.

Watch This Hong Kong Protester Instantly Neutralize Tear Gas (3 minute read)

A short video shows a protestor in Hong Kong neutralizing a tear gas canister by placing it inside a thermos and shaking it. The protestor reached out and announced that the dark substance seen being poured out of the canister was mud. Tear gas canisters contain chemicals that burn to create a reaction that makes noxious fumes. The fumes work on similar chemical receptors as ones activated while eating wasabi and mustard but are more potent. An expert on tear gas has confirmed that shaking a canister inside a thermos filled with mud would be able to stop the reaction causing the canister to burn, as well as clogging up any pores to prevent it from working after it is released.
