The Dark Energy Survey (DES) created a map of 26 million galaxies, the biggest map of the Universe to date, by charting the distribution of matter across the cosmos, per Nature's Davide Castelvecchi. The data from the map has since revealed that the Universe may have less clumps of matter than cosmologists previously thought.

Why it matters: "If confirmed, this gap could mean that mass has been clumping at a lower pace than predicted, potentially revealing new physics," writes Castelvecchi. "For example, it could point to unexpected interactions between dark matter and dark energy, or to new types of neutrinos."

Background: Castelvecchi explains that when the Universe was created roughly 14 billion years ago, matter was spread evenly across it, making it "extremely smooth." As time has passed, cosmologists have found that mass has been "clumping together" into galaxies, stars and other entities at a consistent rate — but now DES' latest data has led scientists to think the clumping may have happened more slowly.

Limitations: DES' findings were based on photos of the Universe produced by measuring "the cosmic microwave background" or as Castelvecchi calls it, "the afterglow of the Big Bang." Survey leaders note that the technique is still "within the margin of error" but add that their data has helped them become a major competitor in the cosmology research field. Note that the DES results have not yet been peer-reviewed, but were presented at a meeting Thursday with the American Physical Society at Fermilab.

Tech scrambles to derail inauguration threats

Tech companies are sharing more information with law enforcement in a frantic effort to prevent violence around the inauguration, after the government was caught flat-footed by the Capitol siege.

Between the lines: Tech knows it will be held accountable for any further violence that turns out to have been planned online if it doesn't act to stop it.

Uganda's election: Museveni declared winner, Wine claims fraud

Yoweri Museveni was declared the winner of a sixth presidential term on Saturday, with official results giving him 59% to 35% for Bobi Wine, the singer-turned-opposition leader.

Why it matters: This announcement was predictable, as the election was neither free nor fair and Museveni had no intention of surrendering power after 35 years. But Wine — who posed a strong challenged to Museveni, particularly in urban areas, and was beaten and arrested during the campaign — has said he will present evidence of fraud. The big question is whether he will mobilize mass resistance in the streets.

Off the Rails

Episode 1: A premeditated lie lit the fire

Beginning on election night 2020 and continuing through his final days in office, Donald Trump unraveled and dragged America with him, to the point that his followers sacked the U.S. Capitol with two weeks left in his term. Axios takes you inside the collapse of a president with a special series.

Episode 1: Trump’s refusal to believe the election results was premeditated. He had heard about the “red mirage” — the likelihood that early vote counts would tip more Republican than the final tallies — and he decided to exploit it.
