Jack Dorsey emailed Twitter employees on Tuesday informing them that they will be allowed to work from home permanently. Some jobs, such as server maintenance, will still require employees to come in. Twitter started encouraging employees to work from home at the beginning of March. The company had predicted that the change would become permanent as people discovered the benefits of remote work. Twitter had plans to start working in a distributed way before the pandemic. It is unlikely to open its officers before September and almost all business travel will be canceled until then as well.

Uber has made an offer to buy Grubhub. Grubhub is currently valued at $4.5 billion. Uber Eats has around 20 percent of the delivery app market share while Grubhub has around 30 percent. The ride-sharing business has seen a steep decline in recent months, so Uber investing more into its meal delivery offerings is expected. Absorbing one of its largest competitors will remove a major source of competition for Uber while expanding its operations.

JPMorgan Chase has taken on US-based cryptocurrency exchanges Coinbase and Gemini as customers. The bank is not processing cryptocurrency transactions but is providing cash-management services. It will process all wire transfers, dollar deposits, and withdrawals. JPMorgan's CEO has been a vocal Bitcoin critic in the past but the bank has been positive about blockchain's potential, even creating its own digital currency in early 2019.

China launched its Long March 5B rocket last week. The rocket has no second stage and so its large core stage fell back to the Earth after it separated from its payload. It is the largest vehicle to make an uncontrolled reentry into Earth's atmosphere since 1991. Some of the components of the rocket engine likely survived. China has previously shown a disregard for debris from its rocket launches. If the rocket had reentered the atmosphere 15 to 20 minutes earlier, it is possible the rocket's debris could have rained down on New York City.

Studies show that ultraviolet light can mutate genetic material inside viruses and other microbes, making it impossible for them to reproduce, effectively killing them. A certain type of UV light is being tested for use against the novel coronavirus. If it is found to be effective, businesses could use it to disinfect surfaces and the air. Installing these lights all over a business would be costly. Amazon has developed a moving robot that can roam and disinfect stores and surfaces using UV lights. A robot like this could be a more cost-effective solution than a full UV light installation in a business.
