There’s a LOT going on as researchers and public health experts race to respond to the Ebola Bundibugyo outbreak in DRC and Uganda before it grows bigger. Some really important questions still open, but also a few answers coming into view🧪 My overview in @science.org is here (and thread coming):

Screen capture of an online quiz result. A cartoon drawing shows a beige and turquoise colored capsule dressed like Clark Kent as he reveals his Superman outfit. In place of a Superman S there is a D. The text reads, “You are doxycycline! You are an under-rated talent who flies below the radar, and others often don't see your true potential. You find that people either really like you or simply don't know you exist. You're on the quiet side and wish people would get to know you more. You tend to not be as physically active as others and often stay indoors to avoid too much sun.
Did you know? Doxycycline is an antibiotic in the tetracycline class. It has activity against a range of bacteria and even some” [cut off]

Trends suggest we may be in for a second round of this winter’s COVID-19 wave after the initial peak in early January. Flu levels increased this week, too, likely due to more influenza B spread. Read this week's full COVID-19 trends report: bit.ly/4tgFVqY
Graphic from The Sick Times sharing the latest COVID-19 trends for February 3, 2026. The graphic presents trends for three metrics: WastewaterSCAN category for SARS-CoV-2, which is "high" (represented with an orange color) and reports a slight decrease (represented with a diagonal down arrow); CDC wastewater viral activity level for SARS-Cov-2, which is "moderate*" (orange) and reports a slight decrease; and CDC COVID-19 test positivity, which is moderate (darker yellow) and stable (side to side arrow). Text below these metrics reads: "*CDC wastewater viral activity levels are calculated based on measurements in the last two years only. They do not account for the lower spread that could be possible with more widespread precautions."

The middle text reads, “COVID-19 levels are going up in parts of the South, West, and possibly the Midwest, while continuing to decline elsewhere. Trends suggest we may be in for a second round of this winter’s COVID-19 wave after the initial peak in early January. Flu levels increased this week, too, likely due to more influenza B spread. — Betsy Ladyzhets.”

The editorial team at Cell extends warm congratulations to Drs. Shimon Sakaguchi, Mary Brunkow, and Fred Ramsdell for their discoveries that defined regulatory T cells as the basis for peripheral immune tolerance. “Tregs” are at the heart of immunity, and the foundational work of the laureates has set up fascinating questions that remain active areas for understanding how our bodies work and for leveraging the immune system to treat disease. We can’t wait to see how their legacy and humanity’s knowledge of peripheral tolerance grow from here.
