Top 2012 Posts: New Homes are Less Expensive to Maintain ? Eye ...

With the end of 2012 approaching, we here at NAHB?s Eye on Housing thought we would take a look at the updates that attracted the most readers over the last year.? In April, we took a look at the cost advantages of new homes.

??????????

April is new homes month. And one of the virtues of a newly constructed home is the savings that come from reduced energy and maintenance expenses.

Data from the 2009 American Housing Survey (AHS) offer proof. The AHS classifies new construction as homes no more than four years old.

For example, for routine maintenance expenses, 26% of all homeowners spent $100 or more a month on various upkeep costs. However, only 11%? of owners of newly constructed homes spent this amount. In fact, 73% of new homeowners spent less than $25 a month on routine maintenance costs.

Similar findings are available for energy expenses. On a median?per square foot basis, homeowners spent 78 cents per square foot per year on electricity. Owners of new homes spent 65 cents per square foot per year.

For homes with piped gas, homeowners spent on average 53 cents per square foot per year. Owners of new homes spent 38 cents per square foot per year.

These data highlight that a new home offers savings over the life of ownership due to reduced operating costs. This is one of the many reasons that the current system of appraisals needs updating to reflect the flow of benefits that come from features in a new home.

    Blades and clades: Why some grasses got better photosynthesis

    Dec. 24, 2012 ? Even on the evolutionary time scale of tens of millions of years there is such a thing as being in the right shape at the right time. An anatomical difference in the ability to seize the moment, according to a study led by Brown University biologists, explains why more species in one broad group, or clade, of grasses evolved a more efficient means of photosynthesis than species in another clade did.

    Their findings appear this week in the Proceedings of the National Academy of Sciences.

    Biologists refer to the grasses that have evolved this better means of making their food in warm, sunny and dry conditions with the designation "C4." Grasses without that trait are labeled "C3."

    What scientists had already known is that while all of the grasses in the BEP and PACMAD clades have the basic metabolic infrastructure to become C4 grasses, the species that have actually done so are entirely in the PACMAD clade. A four-nation group of scientists wondered why that disparity exists.

    To find out, Brown postdoctoral researcher and lead author Pascal-Antoine Christin spent two years closely examining the cellular anatomy of 157 living species of BEP and PACMAD grasses. Using genetic data the team also organized the species into their evolutionary tree, which they then used to infer the anatomical traits of ancestral grasses that no longer exist today, a common analytical technique known as ancestral state reconstruction. That allowed them to consider how anatomical differences likely evolved among species over time.

    Paradoxically, to understand C4 evolution, the researchers focused on the anatomy of C3 grasses in each clade.

    In general what they found was that in the leaves of many PACMAD C3 grasses the veins were closer together, and that the veins themselves were surrounded by larger cells ("bundle sheath" cells) than in BEP C3 grasses. Ultimately PACMAD grasses had a higher ratio of bundle sheath cells to mesophyll cells (cells that fill in the area between veins).

    In C4 plants, such an anatomical arrangement facilitates a more efficient transfer and processing of CO2 in the bundle sheath cells when CO2 is in relatively short supply. When temperatures get hot or plants become stressed, they stop taking in as much CO2, creating just such a shortage within the leaf.

    So PACMADs as a group had developed an anatomical predisposition to C4 photosynthesis that BEP grasses didn't, said senior author Erika Edwards, an assistant professor of ecology and evolutionary biology at Brown.

    "We found that consistently these PACMAD C3s are very different anatomically than the C3 BEPs," she said. "We think that was the evolutionary stepping stone to C4-like physiology."

    When the new leaves turned over

    It didn't used to be this way. Back around 60 or so million years ago, BEP and PACMAD grasses were more similar and both headed in the same direction. The distance between the leaf veins in both clades had been growing closer together. But then they started to diverge in a key way. The bundle sheath cells surrounding the veins in BEP grasses started to shrink down while those in PACMAD grasses stayed larger.

    For a long time the climate didn't particularly punish or reward either of those directions. But then climate changed, and opportunity knocked, Edwards said. Only PACMAD was near the proverbial door.

    "When atmospheric CO2 decreased tens of millions of years after the split of the BEP and PACMAD clades, a combination of shorter [distances between veins] and large [sheath] cells existed only in members of the PACMAD clade, limiting C4 evolution to this lineage," Christin and co-authors wrote in the paper.

    The researchers also found that evolution among C4 grasses was anatomically nuanced. Some C4 grasses evolved because of advantageous changes in outer sheath cells, while others saw the improvement in inner sheath cells.

    Ultimately, Edwards said, studies like this one show that plant biologists have made important progress in understanding the big picture of when and where important plant traits evolved. That could lead to further advances in both basic science, and perhaps agriculture as well.

    "Now that we have this increasingly detailed birds-eye view, we can start to become a more predictive science," she said. "Now we have the raw goods to ask interesting questions about why, for example, one trait evolves 10 times in this region of the tree but never over here. In terms of genetic engineering we're going to be able to provide some useful information to people who want to improve species, such as important crops."

    In addition to Christin and Edwards, the paper's other authors at Brown were David Chatelet and Laura Garrison. Other authors were Colin Osborne of the University of Sheffield in the U.K.; J. Travis Columbus of Claremont Graduate University in California; Guillaume Besnard of the Universite Paul Sabatier-Ecole Nationale de Formation Agronomique in Tolouse, France; Trevor Hodkinson of Trinity College in Dublin, Ireland; and Maria Vorontsova of the Royal Botanic Gardens in Surrey, U.K.

    The National Science Foundation (grants 0920147 and 0843231), the Marie Curie International Outgoing Fellowship (252568) and the Agence Nationale de la Recherche (10LABX-41) supported the research.

    Confirmed: Asteroid won't hit Earth in 2040

    A new study confirms that a huge asteroid will pass harmlessly by Earth in 28 years.

    New observations of the asteroid 2011 AG5 now give astronomers complete confidence that the 460?foot-wide (140-meter-wide) space rock won't hit Earth in the year 2040. When it was discovered last year, scientists said that 2011 AG5 had a 1-in-500 chance of impact with our planet.

    Astronomers solidified the asteroid's harmless status during an observation campaign in October, using the Gemini North telescope in Hawaii. The finding added more support to a NASA study that came to a similar conclusion in June based on months of observations of asteroid 2011 AG5.

    The researchers behind the latest study say the asteroid shouldn't get any closer than 550,000 miles (890,000 kilometers) ? about twice the distance between Earth and the moon.

    "These were extremely difficult observations of a very faint object," the University of Hawaii's Richard Wainscoat, a member of the team of researchers monitoring 2011 AG5, said in a statement. "We were surprised by how easily the Gemini telescope was able to recover such a faint asteroid so low in the sky."

    Just because it is a large asteroid doesn't mean it's easy to see, scientists said. Researchers used the Gemini North to photograph the asteroid three times in October.

    NASA astronomers and other scientists regularly monitor the sky for asteroids that could pose a potential impact threat to Earth. About 9,000 such near-Earth asteroids have been discovered to date, though up to a million or more could exist, NASA scientists say.

    Nearly 95 percent of the largest near-Earth asteroids, those larger than 1 kilometer (0.6 miles) in size, have been identified, NASA scientists say. The space agency's Asteroid Watch program to monitor nearby space rocks is based at the Jet Propulsion Laboratory in Pasadena, Calif.

    Striving For Personal Development? Try These Tips! | Samuel Levitz ...

    Self improvement is about bettering yourself and taking on things that improve upon who you are as a person. Personal development usually focuses on increasing your self-awareness, expanding your knowledge, taking steps towards achieving personal goals and working on spiritual growth. Steps for improving yourself are available in the below article. A deeper understanding of yourself can result if you take slow and measured steps moving forward.

    Your body?s health and your mental health are two sides of the same coin, and each has a close effect on the other. Have healthy meals that are full of nutrients, and be sure to exercise as much as you can. Remember that a healthy body can lead to a healthy mind.

    Never take on more than you can handle when you are attempting to achieve your goal. Do your best, but do not overwork yourself to the point of physical or mental exhaustion. You still need to take care of your body when trying to achieve a goal. You will never improve yourself if you neglect your body in the pursuit of personal development.

    TIP! If you?re not living up to the goals that you set for yourself, take a good hard look at what may be wrong. Find out some ideas online and look to others who have similar expectations.

    Therapy might be the solution for people who have serious issues. Self help books are useful to an extent, but they lack the substance or personal touch that a therapist can provide to a patient. Even the simple act of having someone impartial that you can talk to can improve your chances for success. Books don?t offer the opportunity for discussion that psychiatrists can.

    Spend time with people who are like-minded to you. They?ll help you stay on track by being good role models for positive behavior, and you?ll better balance any negative energy you get from people who aren?t as supportive of your self-improvement goals.

    Start organizing your life. You will feel accomplished and your mind will feel clearer. An additional benefit is that the stress you felt from disorganization will be eliminated. Organizing your environment can be a calming and centralizing influence.

    TIP! Your core principles are important, and your actions should reflect them. Your individual core beliefs are what support your sense of self.

    Accomplish the things in life you want to accomplish. A plan for your ideal life is a great starting point, but a plan without action will get you nowhere. Identify your goals and take the necessary actions to make it happen.

    We all make mistakes which includes making poor food choices once in a while. Try to do better next time, and don?t worry about that cheesecake you had last night. Today is a new day.

    True leaders are humble as they exercise their power. Mention the weaknesses or problems that you see, but be kind when doing so. Do not forget that being a good leader means that you must also know how and when to follow others. A successful leader is one who demonstrates integrity and virtue as an example to others.

    TIP! Try not to take yourself too seriously. We are all but tiny dots in the scope of this universe.

    If you overreact you might be stressed for no reason. Find ways to deal with distressing situations, and take the time to think things through. Mistakes are rarely ever fatal. They can be fixed or dealt with. Always keep in mind the things that you have instead of the things that you may have lost.

    A good self improvement plan has a physical health component. It takes motivation to maintain a healthy lifestyle, both through diet and exercise. When it?s important for you to stay healthy and you do so, you will feel better and it can help improve other areas of your life.

    It can be difficult to reach goals that are too hard or vague, and this may discourage you on your path to personal development. You should make your goal very specific. Goals that are specific will have specific results.

    TIP! To keep from increasing the amount of debt you owe, start putting money into an emergency fund. Too often, unexpected expenses are put on credit cards, which only adds interest to the debt and increases your burden.

    Determine what obstacles are blocking your path to success. This is hard to do for a lot of people. However, being able to identify our weaknesses is the first step to addressing them and ultimately changing them. It?s easier to move forward if you take care of what is standing in your way.

    Getting out and living your life can really enhance your quest for personal development. Don?t sit on the sidelines; take control of your life! Being a passive observer to the world around you removes you from the game entirely. Do not let that happen.
