The lighter side

One thing from the week that made us smile, with a small point attached.
Lighter
Europe's Jupiter probe Juice passed 8,640 km above the Indian Ocean on September 28 and used Earth's gravity to swing 20 degrees onto a new course and gain 3.5 km per second. It needed only one of six planned engine corrections.
1 of 6
planned engine corrections actually needed
Why this mattersThe whole maneuver was free, because they planned around a force that was already there. Before you buy capacity, look at what your business already has in motion, such as an underused tool or a team that knows the work. Route the next project through it.
Lighter
Haifeng Du's team at the Chinese Academy of Sciences found a previously unknown form of iron inside glass beads from Chang'e-6 Moon soil. Each speck holds a stable magnetic signal, a record of the Moon's lost magnetic field, published September 16 in PNAS.
2 beads
glass specks holding the Moon's old magnetism
Why this mattersNobody designed those specks to keep records, and they kept them anyway. Your company has the same accidental archive sitting in old payroll files and ticket queues. Pick one question you keep guessing at, such as why people leave, and go look there first.
Lighter
Priya Banerjee at the University at Buffalo, with Jerelle Joseph at Princeton, found that RNA gathers into protective droplets about 10 degrees Celsius sooner than DNA. The only difference is one oxygen atom per sugar unit.
1 atom
the only difference between the two molecules
Why this mattersOne atom of difference decided which molecule could do the job. Small details in your own setup carry that kind of weight too. Read the first sentence of your job ads and the first line of your welcome email, because those two lines decide who applies and who stays.

Research and engineering from the week, with what each one suggests about running a business.
Science
Changgan Zeng and Guanghui Cheng at the University of Science and Technology of China, with Frank Wilczek at MIT, put a superconducting film inside a small sealed cavity and let the restless energy of empty space act on it. The temperature at which it carries current without resistance rose by up to 5.4%, published October 3 in Nature.
5.4%
gain from the empty space around the material
Why this mattersThey changed nothing inside the material, only what surrounded it. Output often works the same way, so before you rebuild a process, look at the conditions around it. Cut the meeting load and the interruptions on one team this month and measure what changes.
Science
Begona Vila at NASA Goddard and Vanessa Bailey at the Jet Propulsion Laboratory tested the pointing system on the Nancy Grace Roman telescope in late September. It held its aim to better than one hundred thousandth of a degree for eight hours, which the team compared to aiming a laser at a dime from 150 miles away.
8 hrs
of steady aim, checked four times a second
Why this mattersThe guide system checks its own position four times a second, which is why the long hold works at all. A yearly review cannot do that. Ask managers for one line per person every two weeks, and you will catch a problem while it is still small.
Science
Martin Rey at the University of Bath, with the University of Chicago and a Paris astrophysics institute, simulated how the universe's first stars lit up their surroundings and made carbon, oxygen and iron. The run used 40 million processor hours, and four papers came out of it in the Open Journal of Astrophysics.
40m hrs
of computer time behind four published papers
Why this mattersFour papers out of one very expensive run is a good return, because they decided what they wanted to learn before booking the machine. Do that with your next consultant or software trial. Write the three questions it has to answer, then judge it on those.
