Candle Flame Oscillations as a Clock
Todays candles have been optimized for millenia not to flicker. But it turns out when we bundle three of them together, we can undo all of these optimizations and the resulting triplet will start t…

CERN scientists find evidence of quantum entanglement in sheep
Update: did you enjoy our April Fool’s day story? While sheep do roam the CERN site and exhibit interesting flocking behaviour, no evidence has been found of their quantum entanglement (yet). However, CERN is participating in the International Year of Quantum Science and Technology . You can see the list of public…

NIST was 5 μs off UTC after last week's power cut
If you were 5 microseconds late today, blame it on NIST. Their facility in Boulder Colorado just had its power cut for multiple days. After a backup generator failed, their main ensemble clock lost track of UTC, or Universal Time Coordinated. But even if you used the NTP timing servers they run, they were never off by…

AI helps unravel a cause of Alzheimer’s and identify a therapeutic candidate
A new study found that a gene recently recognized as a biomarker for Alzheimer’s disease is actually a cause of it, due to its previously unknown secondary function that triggers a pathway that disrupts how cells in the brain turn genes on and off.

CRISPR fungus: Protein-packed, sustainable, and tastes like meat
Researchers have successfully used CRISPR gene editing technology to create a fungi strain that is highly efficient, more nutritious, and significantly more sustainable than its natural counterpart. The fungus Fusarium venenatum already stands out for its meat-like flavor and texture, leading to its approval for food…

The shadows lurking in the equations
If you've ever graphed equations, chances are you have only ever graphed equations in what I refer to as "Binary mode" - which draws a line where the equation is EXACTLY equal, and leaves white everywhere else.

What Is Entropy?
People say many things about entropy: entropy increases with time, entropy is disorder, entropy increases with energy, entropy determines the arrow of time, etc.. But I have no idea what entropy is, and from what I find, neither do most other people. This is the introduction I wish I had when first told about entropy…
