This is a plant picture I took last month at Disney World. At first I thought the plant was some sort of viburnum, but while catching up with Jenn Forman-Orth's wonderful Invasive Species Web log, found this post showing a plant called Brazilian pepper, considered to be a highly invasive introduced species in Florida. So I sent the picture off to several plant identification groups on flickr and the ID came back... Schinus terebinthifolius AKA Brazilian Pepper or Christmas Berry.According to the University of Florida's Center for Aquatic and Invasive Plants, this species is from South America and has been aggressively colonizing a wide range of habitats in South Florida, replacing native plants. As so many other plants, Brazilian Pepper was introduced as an ornamental. The orange berries are attractive to birds and mammals and this combined with a high germination rate under a range of conditions appears to be the main factor in it's spread.You might think that invasive species are just a major problem in places such as Florida but Kansas has it's own collection of problem introduced species. The USDA's list of Kansas invasive plants alone has 35 species on it and the list is very incomplete. Some of these species such as musk thistle are obvious pests, but others such as Russian Olive, Japanese Honeysuckle, Tree of Heaven and certain types of St. Johns wort are less well known invasives.An example of a potentially invasive ornamental, one that I have in my garden, is "Zebra grass", Miscanthus sinensis. This plant isn't in the same league as Kudzu but it is a plant to watch according to the Global Invasive Species Database.So think carefully before you buy that ornamental. Get the scientific name and find out if it is an invasive species-not all invasive species are officially banned so you can't rely on the plant being environmentally friendly just because it is at your local nursery.If you want a particular type of plant, often there are native or a least non invasive alternatives. One useful source for alternatives from the Brooklyn Botanical Gardens also has tips on garden design and gardening for wildlife. Another useful site is the Global Invasive Species Database, mentioned earlier. This is a good site because it will clue you in to potential problems, such as zebra grass so you can do a little prevention. Also check out the Invasive Species Weblog for quick updates. Of course our local extension agents can help you as well.
Obama may look like the winning horse leading the pack at the beginning of this year's Presidential race, but he won't be able to keep up the pace all the way to the finish line. He isn't seasoned. He isn't experienced.
Neither he or Edwards have the lineage behind them that would be required to go the distance.
Still, Obama is working the track and has picked his way from the back of the pack and moved into a key position to make a run for the final stretch. It hasn't been an easy task. He has been hit by dirt and mud as much as any of his opponents. He seems to be gaining speed. He is a full length ahead of Edwards and Edwards is a nose in front of Clinton.
I am glad I have my bet on Clinton though. She is saving herself for the finish line. She has great stamina, loves to be pushed for a grand finish and is well seasoned and confident. She stands head and shoulders above the competition because of her previous experiences in other races such as these - some of which she watched from the sidelines.
Obama has blinders on; he won't be able to see the filly passing him on the inside track until he begins to taste the dust that is stirred up as she leaves him far behind.
And she hasn't even begun to work up a lather.
The location of the picture posted in the previous installment was identified in the 5th comment. I was tempted to make this one impossibly hard, but I don't think I've done so.This time I won't give any hints except to say it is within the city limits of Lawrence.As before, I hope it causes you to be just a little more aware of the many interesting things there are to see here in town.Here is a small portion of the picture. Each day or so I'll post a version which shows a larger portion of the image.
This is visible from somewhere on the "T" route, so it is not in some hidden corner of town.
Here is the full image of one of the KU buildings on the south side of Bob Billings (15th St), west of Crestline. I'm not sure if this is the building with the pottery kiln.
A favorite online read is Edge which bills itself as representing the third culture. The third culture refers to those intellectuals who bridge the sciences and the humanities, what C.P. Snow referred to as the "Two Cultures". One feature of Edge is a series of contributed response to some important question of the year. This year's question is "What have you changed your mind about?" and the responses are quite fascinating. At least the scientist's responses should put to rest the notion often bandied about by non scientists that scientists are inflexible and dogmatic.Here are some mind changers worth checking out:Paul Davies used to be a committed Platonist. About time he came around to my type of thinking.Lera Boroditsky has decided that language can change our sensory perceptions after her experimental data contradicted her original and long held belief.William Calvin has changed his mind about global warming after visiting Greenland.Roger Bingham has given up evolutionary psychology..or at least what had been the prevailing notion of how the human mind worked.Finally on a pessimistic note but he may be right, Lee Silver concludes that in contrast with what intellectuals like to often believe:" While its mode of expression may change over cultures and time, irrationality and mysticism seem to be an integral part of normal human nature, even among highly educated people. No matter what scientific and technological advances are made in the future, I now doubt that supernatural beliefs will ever be eradicated from the human species."What have I changed my mind about? Over time I have gradually shifted my belief in the balance of nature, now believing that the biological world consists of populations opportunistically evolving and that the balance of nature, like design, is an illusion.What other mind changers are out there? How have your beliefs changed?
The end of a year unavoidably brings various "top 10" or "Break through" lists and science is no exception. So much happens in science and technology that a single list may not be meaningful. So I decided instead to sample some of these science lists which you can look at for yourselves.Popular Science has a "Best of What's New" issue online. Their innovation of the year goes to a private company called Nanosolar which has found a way to cheaply produce a low cost coating that can convert solar energy to electricity. Popular Science is mainly oriented toward applied science and technology, so I am pleased to see that they also chose to recognize advances in detecting planets orbiting other stars. Some of their picks are potentially very disruptive technology. Take the Meraki Mini. This is a Wi Fi device with an important difference:"...add more Minis, and the network can blanket acres. So instead of all your neighbors paying an ISP, you could let them tap into your connection. To boost the whole network's bandwidth, just plug any of the Minis into another wired link."This could be very disruptive to local broadband companies. Heads up Sunflower!Science Magazine has a very different list in their Break Through Issue more oriented to basic science. The Break through of the year is not really a single break through per say but a recognition of how faster cheaper DNA sequencing methods are making it possible to really study genetic variation in humans. These methods have the potential to provide new insights into disease as well as human evolution, but also raise privacy and ethical concerns.Runners up include a new technique for reprogramming cells, new semi conductors and superconducting compounds, and strangely enough a brute force proof that checkers between players with perfect foresight leads to a draw. May seem almost intuitive but demonstrating this has involved new techniques in information processing and artificial intelligence that may be useful in other areas such as deciphering sequences of DNA.The Guardian has a biology laden list. The human genome is tops as it was in the Science list, but they also included the finding that skin cells and other sorts of cells in the body can be reprogrammed relatively easily to behave embryonic stem cells. If this discovery pans out, it could much of the ethical debate about harvesting stem cells from embryos to rest.Finally Scientific American has a "Top 25" list. Not presented in any particular order the list, has some overlap with the Guardian's list but also includes the spread of hospital infections caused by antibiotic resistant staph bacteria (Can you spell evolution?). Climate change received a lot of play on this list as it did on most of the other lists including a special report. One intriguing change that is often ignored in the popular press is the resurrection of nuclear power as a serious option including a proposal to build the first nuclear power plant in this country in 30 years. Nuclear technology has not stood still since the 1970's and reactor builders claim that today's designs are much more efficient and safe.As should be clear, many of the top stories of 2007 really are a recognition of technological or scientific trends that began before 2007. For instance, over at Space.com the big space events in their Top 10 list include planetary flybys, the successful Bigelow space station prototype, along with the privatization of space flight, and more space activity from Asian countries, especially China and Japan.It is hard to believe that the Space Age is 50 years old taking Sputnik as the starting point. Considering all the optimistic predictions made early in the Space Age, it may seem we haven't done much- remember the movie 2001. But given the cost of getting into space we have done pretty well. For instance, advances in robotics have taken us in directions and provided us with opportunities for exploration that we didn't envision in the late 1950's. Who would have thought that a pair of mechanical rovers would have allowed us to learn so much about Mars!I hope people enjoy looking at these lists...what is big in science in your mind? What trends are being ignored? What's coming up next?
Of course my wife is nothing like I portrayed her in my last post, and she got me a macro lens for Christmas so I can take even more pictures of critters only a biologist could love. After Church today I taken with this sedum in my garden peeking through the snow. By the way, I am addicted to flickr and clicking on the image will take you into my public photo stream.
http://worldonline.media.clients.elli... morning I received a call from my wife asking me if I had seen the footprints in the yard. She had noticed them when she was leaving for her job in Topeka."Definitely human footprints only the person was barefoot and my boss said that there could be a homeless person living in the woods.""Kay, that sounds really unlikely to me but this is Lawrence, and we've had other strange things happen such as the escaped cows in our backyard..so I will go look."So out I went and I did find some prints, but they were not very deep..."Hey Kay nope not human, I think rabbit""But they look like bare feet you can see the toes and everything.""Nope rabbit""Well how do you know? Were you there? After all you can't test anything that happened in the past""Kay, I have seen rabbit footprints before and these are rabbit.""Just because you are trained as a biologist doesn't mean I am wrong...you are just plain dogmatic. They looked human to me. You are being dogmatic.""This is just based on experience...Kay look at this picture. I wasn't about to freeze my toes off here but notice how much deeper my shoe print is than the the ones like you found."http://worldonline.media.clients.elli..."I still think they are human. Why do you always have to explain everything away as something ordinary? Just a rabbit...huh maybe they are that hobbit man or a gnome. A baby Sasquatch. There all kinds of strange sightings even in Kansas.""Kay I am a scientist and we look for the simplest explanations first.""That is silly, all you scientists think alike. It is some sort of liberal group think. You need to think outside the box. Maybe you should go work for the government.""What does that have to do with anything?""Well everyone knows those government scientists fake data..if you are told to think rabbit then you're going to think rabbit.""Besides that rabbit idea is just a theory and scientists deal with empirical facts-not interpretations."Sigh...fortunately at that point my cell phone died.Note: Any relationship to current public discussions about evolution or global warming is purely coincidental.http://worldonline.media.clients.elli...
I've only gone to KU basketball games for the last few years. Hearing Hank's announcing at the games seemed so natural that I thought nothing of it. I assumed he'd been doing it for years.The first time I remember hearing Hank Booth as announcer was at the Jaycee's fireworks display, back when it was held in Memorial Stadium.Recently I've written about some of the things that I remember about Lawrence and many have added their recollections. By training and by inclination I'm an engineer. I prefer facts to opinion...even when the opinion is my own.Hank Booth is every bit as much a part of Lawrence as is Dragstrip Road, the Sunset Drive-in, or Woolworth's. That's an opinion.College football and basketball are all about the money. That's an opinion, too.KU basketball games won't be the same without Hank Booth as announcer.That's a fact.Add him to the list of things we remember about Lawrence.
While traveling to Disney World the other week, I picked up a copy of Scientific American Mind to keep myself from being too bored on the flight. One by Sabine Miller called "Amputee Envy" concerns what she terms "Body Identity Disorder" (BID). People with this extremely rare disorder desire to have one or more of their appendages removed, and some actually have such discomfort that they request that the appendage be removed. A summary of the article is here.I had heard about this sort of thing and chalked it up to being a sexual fetish. The reality appears to be much more complex. Some appear to be seeking attention rather than any sort of sexual gratification. But most interesting to me is that at about two thirds of the disorder report that amputation will enable them to express their "true" identity. Thus, there may be a parallel between this disorder and Gender Identity Disorder (GID), which is of personal interest to me. Indeed there are some interesting parallels-both disorders arise early in life, and sometimes the discomfort (which can be extreme) is only resolved through surgery.One might think that these sorts of identity statements are merely part of our modern cultures preoccupation with identity or authenticity, but some cases of BID appear to arise from irregularities in how the body is mapped out in the cerebral cortex. Indeed, sometimes temporary cases of body image problems result from brain tumor, injury or disease. When the disease or injury is fixed, the body image problem goes away.The article also address the issue of surgery for BID cases. Some ethicists argue that, as in the case of certain types of GID, if the person is fully informed of the risks and is not psychotic then surgery ethical. Other ethicists consider this wrong headed and that the Doctor must protect the patient from his or her "irrational desires."Again this sort of debate parallels that about Gender Identity Disorder. Since Gender Identity Disorder is much more common, there is actually standard of care called the Benjamin Standard of Care to provide a way to select those most likely to benefit from sexual reassignment surgery. So lots of interesting things in this article to chew on. What makes our identity? Is it merely socially constructed as some would have us believe? How much is changeable about our identity? What are the boundaries of ethically acceptable medical intervention?There are lots of other interesting articles in this magazine...so you might look for it at your newsstand or for purchase online at www.SciAmMind.com.Citation: Sabine Miller(Dec 2007/Jan 2008) Amputee Envy Scientific American Mind 18(6) pp 60-65Other links:BIID-Info.orgWorld Professional Association for Transgender Health
My wife and I returned from Florida last Friday just in time for last week's snow. And as I write, it is snowing again. But the discussion section in the Lawrence Journal World is hot today because of a column by Cal Thomas in which he accuses Al Gore and other believers in global warming as being fundamentalists. He cites a global warming skeptic "Paleoclimate scientist" Bob Carter as writing""In one of the more expensive ironies of history, the expenditure of more than $50 billion (U.S.) on research into global warming since 1990 has failed to demonstrate any human-caused climate trend, let alone a dangerous one..."This is an interesting comment which flies in the face of the general scientific consensus. So who is the average person to believe? This is important because if Gore and the vast bulk of climate scientists are right then we have an environmental problem that can't wait another 50 years to fix. We are going to have to make both personal and policy decisions either directly or indirectly about this issue.The first thing we need to do is cut partisanship out of the loop. Second of all we need to look at the information that is out there and try to evaluate it as best we can. Fortunately there are several good sources of information. The U.S. government's EPA site (http://www.epa.gov/climatechange/) is much improved in terms of its coverage and I strongly recommend exploring its links. Another site is the National Oceanic and Atmospheric Administration's Global Warming FAQ which gives a quick synopsis the current consensus on global warming. There is plenty of room to discuss what sorts of solutions - free market, government incentives and mandates, individual action but denying what we are doing to the environment is not productive.As for non governmental sources, Science Daily keeps tabs on climate change at http://www.sciencedaily.com/news/earth_climate/global_warming/ and this is perhaps the site for the latest developments in our understanding of climate change.If you are a regular blog reader, a good unbiased site is Real Climate (http://www.realclimate.org/). This blog's contributors are climate scientists-not geologists and not ideologues. Of course look at some of the advocacy sites on the left and the right-what ever your ideological fancy, but do yourself and civilization a favor and check the claims that are made on those sites against each other and come to an honest judgment for yourself about where the truth most likely is. Don't just believe some numskull on the left or the right because you agree with their ideology, unless the numskull happens to be me of course.In the interest of full disclosure I am pretty much in agreement with the scientific consensus but some of my conclusions about where we stand probably go beyond the scientific consensus:1. Global warming is real and not just an artifact of changes in data collection.2. Much but probably not all of recent global warming is due to human activity including burning of fossil fuels but also deforestation and increased agricultural production.3. Global warming may be to the point that we can do little to affect it quickly.4. Climate change happening more rapidly than we thought possible even five years ago and may be happening more rapidly than many populations can adapt to.5. There is no magic bullet to solving global warming and we probably will need to make some uncomfortable choices concerning energy sources and (dare I say it?) some sacrifice of living standards.6. Poorer countries will be more severely affected than developed countries.7. We have exceeded the ability of the planet to sustain our current population, and global warming is interacting with other human disturbances to bring about an irreversible biodiversity crisis.8. There is still hope for our species but our environment is going to become biologically impoverished in ways we might not like.Of course all comments are welcome; just play nicely.
Here are the answers, based upon what I know and what was said in the comments, please let me know of any errors. 1. Where and what was Griff's? A burger place on 23rd, located approximately across from where Mongolian BBQ is now, It was in an unusual A-frame building 2. What major retail chain had a store where the Antique Mall is now located. (Hint, it has moved again since then). For extra credit, where did it move to before moving to its present location? J.C. Penney's, It moved to occupy the Montgomery Ward's location near 23rd and Iowa before moving to its present location. 3. Name a store that is now located where Woolworth's used to be located. Kinko's, Saffee's, Chipotle 4. Bucky's originally had another name, what was it? Sandy's. An article this week reported Bucky's closing. 5. Where did George's Hobby Shop used to be located? The Malls, 23rd and Iowa. It moved to Paper Warehouse, before moving to a building behind. Someone also reported it being at 19th and Mass, if so, that was before my time. 6. What was the name of the drive-in theater that was located on 6th Street near where Sonic is now located? Sunset Drive-in 7. There was yet another drive-in theater in town, where was it? For extra credit what was its name. Please tell me, I don't know. This was before my time, I'm told it was the Chateau on 23rd street, near where Laird Noller is now. Or was it the Lawrence Drive-in? 8. Where was the Vista drive-in located? On 6th street. The "Olympic" pool was down the streeon on the other side. 9. What is the name of the restaurant that occupied the building where Bambino's is now? Cornucopia, the only place I've ever eaten quiche. 10. Where was the "Campus Hideaway" located? Just north of South Park.There were a number of us who remember going to the Sunset, climbing on the train, and seeing Leo Beuerman. Other recollections (a partial list)The church at the corner of 6th and Maine, followed by Alfie's?, now Taco John'sQuantrill's Flea Market.

...Didn't see Jenning's Daylight Donuts mentioned. Did anyone ever go to the the Aqua Forum to get tropical fish? I remember it on the east edge of town on 23rd Street before it moved to the Mall, behind where Wendy's is now... until is closed There was also Jayhawk Tropical Fish.Thank you, everyone, for a nice (I might even say wonderful) trip down memory lane.
It should appear as a fast moving bright star rising in the NW. It should climb to as high as 45 degrees above the horizon before setting in the east.There should be another opportunity just before 6PM on Saturday evening.Here is a NASA site where you can look to see when the Station will be passing overhead at a time when it is visible (dawn or dusk). Click the "Input" tab and enter your zip code, then click "Next Sighting". This applet requires Java be installed, so if you see nothing, that is probably why.It is easy to see. With binoculars, you might be able to see it as more than a bright white dot.

I propose that if we took the time to look more closely at all the things around us each day, we would be the richer for it. So here is what I propose to do:I cropped a picture I took to show a small and hopefully not easily recognizable portion.
Your mission, should you choose to accept it, is to figure out what or where it is. At regular intervals, probably once a day, I'll expand what the image shows or provide a hint, until someone correctly identifies it. If it is a foolish idea, I'll be flamed in comments--if indeed there are any at all. It is just a silly little idea, anyway. I hope you'll spend a little more time each day paying attention to the many interesting things around you.
If you spend much time driving (or taking the T) around Lawrence you will surely be able to see this. Here is the next image:
One more, if you still aren't sure:
Not much of a surprise, but here is the complete image:
And here is a short history of the Castle Tea Room.
If you're a long time Lawrence resident, here's a little quiz to see what you remember about Lawrence the way it was...
- Where and what was Griff's?
- What major retail chain had a store where the Antique Mall is now located. (Hint, it has moved again since then). For extra credit, where did it move to before moving to its present location?
- Name a store that is now located where Woolworth's used to be located.
- Bucky's originally had another name, what was it?
- Where did George's Hobby Shop used to be located?
- What was the name of the drive-in theater that was located on 6th Street near where Sonic is now located?
- There was yet another drive-in theater in town, where was it? For extra credit what was its name. Please tell me, I don't know.
- Where was the Vista drive-in located?
- What is the name of the restaurant that occupied the building where Bambino's is now?
- Where was the "Campus Hideaway" located?
Extra credit if you: 1. Went to a movie at either of the drive-in theaters mentioned above. 2. Actually climbed on the train in the "Train Park" (Buford M. Watson, Jr. Park) before the fence was placed around it. 3. Ever saw Leo Beuerman in his little cart downtown. Triple extra credit if you ever bought a pencil from him.
Sometimes you sit and waitThere is nothing you can doWhen everything seems to be going wellthe other shoe dropsLeaves you wonderingIs it really worth it?You feel failure and despairDon't know where to turn or what to doYou feel the will leave through your fingertipsThe tears flow down your faceIs it really worth it....to fail?Everyone dies after allthere is no where to reach toNo one to pull you upIf you have used all your strength Do you just let go? Fall like a petal from a wilted flower...hit the ground and get swept away......join the petals that have left before you...reunite in the eternal garden......
All it took was the thought of something that will never beRemembering that love rarely comes alongAnd when it does it usually doesn't lastThat one moment, one ache in my heartTo take me back to JulyBack to the moment I answered the phoneHeard the hesitation in his voice"Hey Claire, have you talked to mom yet?"I hadn't he would soon realizeHe had to be the one to tell me"Pete shot himself last night, he's dead"Not a day goes by that I don't feel the emptinessThere is something that is missing in my lifeThere is a void that no one can fillNothing will ever heal that painThose that leave me behind, don't leave a voidBecause the void was already thereI am broken, unable to move onI am vase that cannot be filledFor it is crackedA dream that goes unfulfilledBecause I never wakeI am the rose that never blooms Because of the late spring frostI am the wounded horse That must be laid downI will never be whole againThe pain continues to comeIn waves it flows through my bodyLike my body has been hit by a volt of lighteningI fall limp after tears have run til' they run no moreMy body is exhaustedI fear lossI fear Saturday calls from himI miss the laughterThe jokes about "Lak MiSing"This American Life will never be the sameThe life I live will never be the same
There is a movement underway to goad the presidential candidates into a debate on science policy. Given that so many of our issues today involve science, it is only fair that the voters get to hear candidate's views on science and science priorities.

If you are a Boston single, as of today you have a new option to find a mate. A company called scientificmatch.com has a new wrinkle in the match making game-matchmaking based on DNA analysis. The idea is to find a mate based on the compatibility of the genes related to characteristics of the immune system. The company's website claims:
"When you share chemistry with someone:
- 1. You love their natural body odor. They smell "sexier" than other people.
- 2. You have a more satisfying sex life.
- 3. If you're a woman, you have more orgasms.
- 4. There's significantly less cheating in your relationships than if your DNA isn't matched properly.
- 5. As a couple, you're more fertile.
- 6. Your children have a better chance of being healthy."
Today, Gyroduck commenting on a Journal World article, Drawing on God posted a link (http://www.youtube.com/watch?v=DfPepr...) from You Tube explaining a really puzzling aspect of quantum mechanics. Hop on over to view the video. Also read Gyroduck's comment linking the observations discussed in the video to prayer. Is Gyroduck right to make this connection?
