Bluesky Developer Waitlist

Bluesky is an open social network built on the AT Protocol, a flexible technology that will never lock developers out of the ecosystems that they help build. With atproto, third-party can be as seamless as first-party through custom feeds, federated services, clients, and more. If you're a developer interested in building on atproto, we'd love to email you an invite code. Simply share your GitHub (or similar) profile with us via this form. Read more about the AT Protocol here: https://atproto.com/ and check out some third-party developer projects here: https://atproto.com/community/projects

The open source licensing war is over

It’s time for the open source Rambos to stop fighting and agree that developers care more about software’s access and ease of use than the purity of its license.

Analysis of a super-transmission of SARS-CoV-2 omicron variant BA.5.2 in the outdoor night market

IntroductionThe COVID-19 pandemic continues to ravage the world, and mutations of the SARS-CoV-2 continues. The new strain has become more transmissible. The role of aerosol transmission in the pandemic deserves great attention.MethodsIn this observational study, we collected data from market customers and stallholders who had been exposed to the virus in the Qingkou night market on July 31 and were subsequently infected. We analyzed the possible infection zones of secondary cases and aerosol suspension time in ambient air. We described and analyzed the characteristics of the secondary cases and the transmission routes for customers.ResultsThe point source outbreak of COVID-19 in Qingkou night market contained a cluster of 131 secondary cases. In a less-enclosed place like the Qingkou night market, aerosols with BA.5.2 strain released by patients could suspend in ambient air up to 1 h 39 min and still be contagious.ConclusionAerosols with viruses can spread over a relatively long distance and stay in ambient air for a long time in a less enclosed space, but shorter than that under experimental conditions. Therefore, the aerosol suspension time must be considered when identifying and tracing close contact in outbreak investigations.

The immunology of long COVID - Nature Reviews Immunology

SARS-CoV-2 infection can lead to a diverse array of chronic symptoms, collectively termed ‘long COVID’. In this Review, Altmann and colleagues explore current thinking about the pathophysiology of long COVID and discuss potential immunological mechanisms.
