Which alternative energy source is the best?

Question: Which alternative-energy source is the best?

Michael Klare: We, have to face a short term problems of liquids, because especially in this country we are so dependent on motorize vehicles that is the short-term crisis. We are running out of oil for cars and trucks and buses and planes and everything else. We need a liquid alternative. So people tell me, well lets have more wind power and more solar power, which is very appealing. Some people say nuclear power too, but none of those are going to solve our short-term crisis of liquids, and so for liquids I think the most promising is second generation Ethanol. Not Ethanol derived from food crops like corn, but Ethanol derived from the corn stocks and woodchips and other biomass using enzymes what’s calls cellulosic ethanol. This was very promising to me, but we do not have a single functioning cellulosic ethanol plant in commercial scale, cellulosic ethanol plant in this country at this time.

Question: What would it take to get us there?

Michael Klare: A lot of money, a lot of investment too. I mean the technology is ready, no, I shouldn’t even say that, its on a laboratory scale we have this technology, but we have to move it to commercial scale production and a lot of investment money has to be put into this. This I think is the priority, so that’s the short term crisis of liquid the transportation fuels I think is bio - developing nonfood crop bio fuels. Looking into the future the most promising strikes me is solar power, because I think that’s where the most progress is being made to harness the power of the sun, but there is a mismatch between where the sun is strongest in the American Southwest and where they need is greatest which is in Northern California, in the Midwest and in the Northeast and we don’t have the transmission lines and the infrastructure and so on, so there too, you need a lot of investment and so forth.

Klare is intrigued by solar energy but says that we are still far from making it an economically feasible alternative.

Scientists sequence the genome of this threatened species

If you want to know what makes a Canadian lynx a Canadian lynx a team of DNA sequencers has figured that out.

Surprising Science
  • A team at UMass Amherst recently sequenced the genome of the Canadian lynx.
  • It's part of a project intending to sequence the genome of every vertebrate in the world.
  • Conservationists interested in the Canadian lynx have a new tool to work with.

If you want to know what makes a Canadian lynx a Canadian lynx, I can now—as of this month—point you directly to the DNA of a Canadian lynx, and say, "That's what makes a lynx a lynx." The genome was sequenced by a team at UMass Amherst, and it's one of 15 animals whose genomes have been sequenced by the Vertebrate Genomes Project, whose stated goal is to sequence the genome of all 66,000 vertebrate species in the world.

Sequencing the genome of a particular species of an animal is important in terms of preserving genetic diversity. Future generations don't necessarily have to worry about our memory of the Canadian Lynx warping the way hearsay warped perception a long time ago.

It is easy to see how one can look at 66,000 genomic sequences stored away as being the analogous equivalent of the Svalbard Global Seed Vault. It is a potential tool for future conservationists.

But what are the practicalities of sequencing the genome of a lynx beyond engaging with broad bioethical questions? As the animal's habitat shrinks and Earth warms, the Canadian lynx is demonstrating less genetic diversity. Cross-breeding with bobcats in some portions of the lynx's habitat also represents a challenge to the lynx's genetic makeup. The two themselves are also linked: warming climates could drive Canadian lynxes to cross-breed with bobcats.

John Organ, chief of the U.S. Geological Survey's Cooperative Fish and Wildlife units, said to MassLive that the results of the sequencing "can help us look at land conservation strategies to help maintain lynx on the landscape."

What does DNA have to do with land conservation strategies? Consider the fact that the food found in a landscape, the toxins found in a landscape, or the exposure to drugs can have an impact on genetic activity. That potential change can be transmitted down the generative line. If you know exactly how a lynx's DNA is impacted by something, then the environment they occupy can be fine-tuned to meet the needs of the lynx and any other creature that happens to inhabit that particular portion of the earth.

Given that the Trump administration is considering withdrawing protection for the Canadian lynx, a move that caught scientists by surprise, it is worth having as much information on hand as possible for those who have an interest in preserving the health of this creature—all the way down to the building blocks of a lynx's life.
