Flowering curly kale, a variety called Baltisk Rod Purpurkal, being grown for seed at Fresh Roots Farm in Montana. The farm is collaborating with the Organic Seed Alliance on a toolkit for farmers who want to produce seed.

If someone is earning $45,000 a year as a welder, she said, they might not realize how much of that money already goes to fixed expenses. 

IRA FLATOW: And Eva Zurek, who is professor of chemistry at my alma mater, University of Buffalo, in Buffalo. Welcome to Science Friday. 

I think that people find it extremely interesting. Also, this was first theoretically predicted before it was experimentally shown. But I don’t think it’s going to reach room-temperature superconductivity, as far as I can tell. 

When it comes to power, the RadMini Step-Thru has power to spare. Its 48 V battery provides plenty of strength to run that 750 W rear hub motor. Acceleration is quick and smooth, even on grass and dirt. And with a 14 Ah battery, the RadMini Step-Thru offers 672 Wh of capacity. That’s easily enough for 40 km or 25 miles of range on throttle only. But with 5 speeds of pedal assist, Rad Power Bikes claims you can achieve 70 km or 45 miles of range.

“When we were thinking about entering this market, we saw that there were few, if any, competitors that were able to provide the tight tolerance associated with these parts, especially because these parts are very round with little or no flat section,” said Myers, who now serves as York’s president.

Bob Swartz and Kara Noack agree in identifying the biggest hurdle to faster adoption of 3D printing: end-users need to rethink how they approach manufacturing; they need to break out of their mental models both in how they design parts and in how they structure the production process.

What makes this guitar stand out from traditionally manufactured instruments is the lack of a joint between the neck and body of the guitar. This joint tends to create the weak spot that enables Malmsteen and other famous guitar smashers (the Who’s Pete Townshend comes to mind) to break the instruments without a great deal of effort. Sandvik’s guitar’s neck and fretboard were milled in one machine from solid bars of recycled stainless steel, making it stronger than a typical guitar.

People get diversity in tomato or corn, but they tend not to translate that to other crops like cilantro.”

Wroński said that there is an urgent need to equip the Polish helicopters with modern self defence systems adequate to face the threat posed by the modern anti-aircraft measures. Even greater emphasis should be placed on low-level flying, during the pilot training process. When asked whether Poland should modernize its Mi-24 and W-3 platforms, the General said that this should also be done. In his opinion keeping the aforesaid platforms in service will help the pilots to stay proficient, also ensuring continuity in crew generations. In conditions as such they could calmly wait for the new platforms to arrive. General added that around 30 W-3 helicopters that could be modernized soon have already been selected.

Integration. Although metal additive manufacturing can be easier and less expensive than machining, it is not going to replace the ways metal components are manufactured currently. Traditional methods still make the most sense for many parts. Metal 3D printing is simply another tool to add to a tool- and diemaker’s arsenal.

And the other thing that needs to be shown is something called the Meissner effect. So when you put– when a superconductor is put into a magnetic field, it expels the magnetic field. And that’s what lets you have these levitating trains, for example, that go on superconducting tracks.
