Seas on Titan and your heating bill

Like most regions of the country, the area where I live suffered through colder than average temperatures in mid-November. If you pay for your heating bill month by month, you are now facing the sticker shock that results from those bitter times. Happy holidays.

I heat my home with a natural gas furnace supplemented by a woodstove in the living room. It’s a small stove, really designed only for emergencies and for fires built for fun on a Sunday afternoon. In other words, it doesn’t heat the whole house, and it works only with constant tending. But during our cold snap, I built some fires in the woodstove to try to take the edge off the natural gas bill I was incurring. The woodstove is in the same room as the thermostat for the house, though, so heating with it caused the temperatures in the rest of the house to crash. Still, I was doing what I could to lessen what I would later owe the power company.

The main ingredient in natural gas is methane. It’s colorless and odorless, so utility companies add a “rotten egg” smell to it. That way, if there is a leak, your nose becomes aware of it and you can evacuate your home, then call 911.

Methane occurs elsewhere in the solar system besides the Earth. It’s abundant on Titan, one of the moons of Saturn. On Titan, methane is a liquid because temperature there is almost 300 degrees below zero Fahrenheit. Scientists have now plumbed the depths of three frigid seas of methane on Titan. An article online at sciencenews.org told me that the second largest of the seas, called Ligeia Mare, holds enough methane to fill Lake Michigan three times.

NASA’s Cassini probe reached the neighborhood of Saturn in 2004 and it’s still sending back data. The spacecraft was told to send radar pulses directed toward Titan’s seas. Results in some places included two sets of reflected energy. The first set of waves were from radar bouncing off the surface of the methane sea. The second, weaker, set of waves were from radar bouncing off the floor of the methane sea, under the surface. Together, these indicate the depth of the liquid methane.

The shallow parts of the sea are some 20 to 40 yards deep. In other parts of the Ligeia Mare, however, the methane is so deep no reflections from the bottom were detected, indicating places that are more than 200 yards deep.

It’s amazing to me what we are continuing to learn about our solar system — information ranging from data beamed back from a spacecraft landing on a comet to this information about Titan’s methane seas. I’m also amazed by what I owe the power company for methane I used in November — but I’m trying to keep some perspective about it.

Inspiring Teamwork – Arron Carter

It started with a car, a ’69 Corvette Stingray to be exact.

When Arron Carter, the director of the Washington State University Winter Wheat Breeding Program, was in high school his agricultural teacher had a ’69 Corvette Stingray. Every year this teacher would let his favorite senior take the car to senior prom. Carter had never taken an agriculture class before, but he knew he wanted to drive that car.

“Well, if I’m going to be the favorite senior,” Carter said to himself, “I’d better start taking some ag classes.”…

Research Update

Washington State University’s screening continues to find no evidence of glyphosate herbicide resistance in Pacific Northwest wheat varieties

In each of the last three years (2014, 2015 and 2016), the field screening process has involved over 80 varieties, 2,000 advanced breeding lines and more than 35,000 individual plots from WSU cereal breeding and variety evaluation programs. Collectively, varieties included in these trials represent over 95 percent of the wheat acreage planted in Washington.

Want fries with that? Stealth potato virus threatens industry

Newly emerged viruses threaten the U.S. potato industry, including potatoes grown in Washington. Several newly evolved strains of the disease known as potato virus Y, or PVY, can render potatoes unmarketable and reduce crop yield. What’s worse is the new viruses are particularly difficult to detect with the naked eye.
