It was Ada Lovelace Day this past week, So Here's The Life And Times Of Ada Lovelace, The First Computer Programmer. Related: Beyond Emmy (Noether) and Sophie (Germain): Resources for Learning about Women in Math. Also: Take the Guardian's quiz: how much do you know about women in science? Bonus: This Ada Lovelace Inspired Artwork Pits Musicians Against a Robot.

Speaking of women in science, here's a Q&A with physicist Katherine Freese, as she talks neutrinos, women in science, and the hunt for dark matter.

At the Far Ends of a New Universal Law: Beyond the Bell Curve. A potent theory has emerged explaining a mysterious statistical law that arises throughout physics and mathematics.

There are several different experiments hunting for dark matter -- read my 2013 article in Quanta for background context -- and the latest results from two don't seem to be clarifying matters. First, ATLAS revealed no evidence for light dark matter (a.k.a. WIMPs, Weakly Interacting Massive Particles). Adding to the confusion: Dark matter may have been detected in the form of axions – streaming from sun’s core. "Researchers at Leicester University spotted the curious signal in 15 years of measurements taken by the European Space Agency’s orbiting XMM-Newton observatory."

Lockheed Martin Says It'll Have A Truck-Sized Fusion Reactor In 10 Years. Here's What We Know So Far, plus all the details on Lockheed's new compact fusion reactor design. Related: Are there old secrets behind Lockheed's new fusion machine? Then again, don't get too excited, no one has cracked nuclear fusion yet. Lockheed Martin's fusion goals met with its fair share of scepticism. Also: U.S. fusion plan draws blistering critique.

Through the looking glass with switchable mirrors: Electrochemical mirror remains reflective without external power. Related: Atomic trigger shatters mystery of how glass deforms. Also: Artist Carol Milne knits with glass. Per Colossal:

"First, a model of the sculpture is made from wax which is then encased by a refractory mold material that can withstand extremely high temperatures. Next, hot steam is used to melt the wax, leaving behind an empty cavity in the shape of the artwork. Pieces of room temperature glass are then placed inside the mold which is then heated to 1,400-1,600 degrees Fahrenheit depending on the type of glass. Afterward, the piece is slowly cooled over a period of several weeks, followed by a careful excavation process, where Milne delicately chips away like an archaeologist to reveal the final piece."

Urban "Fingerprints" Finally Reveal the Similarities (and Differences) Between American and European Cities. Travelers have long noticed that some American cities “feel” more European than others. Now physicists have discovered a way to measure the “fingerprint” of a city that captures this sense.

Searching for Superconductivity. The discovery involved "little heroism, more luck than good management, and a starring role for a trainee instrument-maker who dozed off." Maybe. "In 1911, in a lab at the Netherlands' Leiden University, physicist Heike Kamerlingh Onnes showed how, below certain critical temperatures, some materials have zero resistance—a discovery that helped create everything from MRI machines to particle accelerators and digital computers."

Relativity and Baseball: "Not even the hardest-throwing pitcher could stand at home plate and throw the ball into the second deck of a baseball stadium. Yet it’s not uncommon for the ball to end up there after being hit by a bat. So, how does that work?"
