But our lives are unaffected.






A Forrester Research report released Monday received a ton of attention for its suggestion that TV and internet usage in the U.S. had reached parity. Now that data is drawing some high-profile skeptics.



The problem is Forrester’s findings don’t remotely square with existing measurement on TV and internet usage. While the study found that in January and February of 2010 consumers reported spending 13 hours per week on both TV and internet, data from Nielsen and comScore (NSDQ: SCOR), arguably the most reliable sources for measurement of TV and internet usage, offer a markedly different picture.

or add an alert for future coverage of Research.



ESPN plans to meet Wednesday with Forrester, which counts the sports juggernaut as a client, to share its concerns. “Our fundamental concern is that, in a very confusing media landscape, we’re trying to answer very important questions about the behaviors of consumers,” said Dave Coletti, vice president of digital media research and analytics at ESPN (NYSE: DIS). “It’s imperative that we answer questions with the right methods.”



In the first quarter of 2010, Nielsen clocked weekly usage at 38 hours and 44 minutes, nearly three times what Forrester found. Over the same time frame, comScore’s account of internet usage was 7 hours and 24 minutes, about half of what Forrester found.



Why these numbers are so divergent cuts to the heart of the difficulties ESPN has with this Forrester study. The Forrester numbers are entirely based on self-reporting, or what the 30,000 respondents to the survey say is their consumption habits. But that’s a subjective metric different from the kind of metered measurement Nielsen and comScore do. They may have their own well-documented faults, but are at least they’re objective.



But what’s more troubling to Glenn Enoch, vice president of integrated research at ESPN, is that in media-research circles, self-reporting is known to be notoriously slippery. “It’s something we’re generally careful about,” he said.



To wit: In a Video Consumer Mapping study conducted last year by Ball State University Center for Media Design that is widely regarded as a landmark piece of research, one of the key findings noted, “Serious caution needs to be applied in interpreting self-report data for media use. TV was substantially under-reported while online video and mobile video usage were over-reported.”



On Twitter, a few prominent self-appointed critics openly questioned Forrester’s findings. Gian Fulgoni, chairman of comScore, had a rather heated exchange with Forrester’s lead researcher on the report, Jacqueline Anderson, in which he questioned the validity not of his own stock in trade—Internet measurement—but the TV numbers.



“Nielsen says TV 140+hrs /mo. You say it’s only 52. Something very wrong,” he tweeted. After a few back-and-forth tweets, Anderson defended the work as “clear” when you examine the year-over-year numbers. “Clear?” Gulfoni shot back. “There’s huge error level.”



Reached for comment, Anderson doesn’t take issue with the veracity of Nielsen or comScore’s numbers. But she feels they are important pieces of a puzzle that isn’t complete without getting the consumers’ perspective. There’s the reality of what metered measurement yields, but to Anderson there is also value in distilling the perception of what consumers believe is the reality of their consumption habit. “In their minds’ eye now, the time consumers spend between mediums is equal,” said Anderson.



In her defense, Anderson stated clearly in a blog post about the research on Forrester’s site that “the data we present in this most recent Technographics® report is self-reported, so the metrics aren’t the same as those you’d see from a Nielsen or comScore.”



However, the very first line of the executive summary on the page where Forrester makes the full research available to its clients seems to pass off the research as what viewers actually consume instead of what they think they consume: “For the first time ever, the average US online consumer spends as much time online as he or she does watching TV offline.”



Anderson believes that the TV vs. internet comparison is not as significant in this research as the growth—or lack thereof—that each medium experienced since 2009. TV consumption didn’t decrease; it just held steady while internet made the huge leaps it took to catch up. “The data in the year-over-year picture is the more important piece of the puzzle,” said Anderson, who also noted that she was cognizant that respondents tend to under-report, but if they’re doing so year-over-year, it’s an apples-to-apples comparison.



But that nuance was apparently lost on the dozens of press outlets who wrote about the research, trumpeting it as some kind of milestone in the growth of U.S. internet usage yet failing to convey that self-reporting isn’t the best basis for declaring a tie between the mediums’ exposure levels. Few referenced the wealth of statistics that demonstrate just how largely TV consumption still looms over internet usage, a dynamic one industry researcher recently put in perspective by characterizing the Facebook audience as being on par with that of PBS. Maybe it’s hard to resist that sexy narrative of the underdog coming from behind to race neck-and-neck with the longtime leader.



Then there’s the very either-or premise of the research to consider. The distinction between TV and online usage isn’t even entirely clear anymore in a universe in which there are a bevy of boxes that deliver programming directly to the TV set via broadband connection. And concurrent usage of TV and online is already a well-noted phenomenon, making any presentation of data that paints TV vs. online as a zero-sum game off the mark.



Perhaps it’s predictable that ESPN would be the one to want to counter the study. Just last week, the network released its own study that sought to minimize the so-called cord-cutting phenomenon, which drew observations that ESPN was only trying to protect its gravy train. And of course, the Forrester research is now being touted as supporting evidence of cord-cutting.



“When we do raise an eyebrow at things like this is, it’s often interpreted as we’re downplaying the potential of digital media,” said Coletti. “Nothing can be further from the truth. I wave the flag for digital media. It’s more about putting on my professional researcher hat and making sure the data that gets into the marketplace is as accurate and reliable as could be.”

JUBA –  After the sound of gunfire fell silent in Southern Sudan, marking the end of one of Africa’s longest running civil wars, Pio Kowr Ding decided he would return home to the autonomous region to take up an agricultural research job with the government.



With a masters degree in soil and land evaluation, and experience working for the Agricultural Research Corporation’s Land and Water Research Center (LWRC) in Khartoum, Ding was keen to help the region rebuild its agricultural research. But when he arrived in 2008 he realised that the task was actually to start from scratch and the living conditions were tough.


“It is very discouraging — completely the opposite of life outside here — and it is difficult to cope,” he says.


Although peace returned to Southern Sudan in 2005, several economically vital sectors in the region lag behind, even as the clock ticks towards the expiry of the five-year lifespan of the Comprehensive Peace Agreement between the north and the south.


As well as claiming 2.5 million lives, the war also drove 4 million people out of the region.


Attracting scientists back is proving tricky. A drive to lure scientists back to rebuild Southern Sudan’s agriculture has attracted just seven researchers so far.


“Those of us who found courage and returned cannot even find research equipment or facilities like the ones we had in the diaspora,” says Ding. “That is why a lot of my friends and colleagues are still there.


Worried by the dismal performance of the sector, Southern Sudan’s government has now looked abroad and brought in the renowned agricultural research scientist and plant pathologist, Joseph Mukiibi, the founder of Uganda’s National Agricultural Research Organisation (NARO), to run a new research institute.


The region ‘could feed East Africa’


Mukiibi, who once led NARO’s research on food crops, forestry and livestock, is now spearheading the re-establishment of a strategic agricultural research plan in Southern Sudan.


“We are to re-establish what existed before, we have to see what is on the ground, what network, which model do we want that will suit Southern Sudan best,” he says.


The government needs to start training its own people, or tap cheaper labour from neighbouring areas, he says.


“This region has a population of ten million people in an area three times the size of Uganda, which has 32 million people. A lot of Southern Sudan is empty land: if the government is serious, it can start agricultural projects here that can feed the rest of East Africa.


The real key, however, is to attract scientists back because, he believes, modern agriculture cannot succeed without research. Mukiibi believes the region has an untapped seam of highly qualified nationals who continue to live abroad.


“Very few people in the diaspora would be willing to leave their plum jobs and comfortable lifestyles to come back home. You can imagine that after 20 years of war, education is limited, people and resources are just not here, and those who are coming back need some time to settle back in.”


Making a start


And the working environment is indeed far from inviting. He recounts the grim state of a former research station in the town of Yei.


“I can tell you it’s empty, in a sorrowful state. There is a lab but it is in darkness. There is nobody and no research equipment, just some dilapidated staff houses, which are empty,” Mukiibi says.


“Can you imagine someone in the diaspora who has a fully functioning lab with running tap water and electricity? And you’re telling him to come to the bush where there is no power, and where he can run out of water and not even have a pit latrine?”


Many Sudanese scientists are proud of their nation but that is not enough. “They cannot eat nationalism,” Mukiibi says.


Human resources are limited but we will start with what we have. We will start small, with one centre, make it functional and, with the experience we get there, we will move to the next centre, learning from mistakes and strengths. We will ultimately build the system.”


Foreign input, indigenous priority


Mukiibi compares the Southern Sudanese experience to that of Rwanda after its civil war and genocide in the early 1990s. The Rwandans “opened up and got people from Uganda and Kenya even as they returned to be trained to take over the operations of their research institutes”, he says.


His team is now developing the strategic research plan, which must be completed by March 2011. It will be based on that of Kenya’s Agricultural Research Institute (KARI) and Uganda’s NARO, and it will be put out for discussion with stakeholders at every step — “that way, you have many chances of having it implemented”.


Other than Mukiibi and Ding, the team comprises a plant breeder, an entomologist, a horticulturalist and an agronomist, all of them Southern Sudanese who have returned since the war ended.


Loro George Leju Lugor, director general of research, training and extension services at Southern Sudan’s agriculture and forestry ministry, makes these points about the plan:


“First, we do not want to rely on imported seeds year in, year out. Second, we want to upgrade our national germplasm of indigenous crops. And third, we want to improve crop production technology for our own consumption and export.”


He says the emphasis should be on indigenous crops in the region’s six agro-ecological zones: green belt, iron-stone plateau, flat plains, Nile-Sobat River, hills and mountains, and semi-arid areas.


Moving into production


At the newly established research unit, Lugor says that seed production and the creation of a database of all locally grown crops will be a priority.


“We are distributing seeds proven to do very well in the agro-ecological zones after importing them from Uganda and Kenya,” Lugor says.


“The production of our own, locally bred seeds, and their distribution to farmers is not something we can do within a year: it will take two to three years to be fully established due to the many challenges involved in conducting research work in the situation we have in Southern Sudan,” he concedes.


Like Mukiibi, Lugor says challenges range from financial constraints, the diversity of the country, and lack of infrastructure and manpower.


Without returning professionals, he says, the region lacks the “think tanks” needed to plan and execute agricultural research work.


“We are making proposals to international research organisations and bilateral partners but it’s not easy to get the money needed. For example, we budgeted for US$56 million but have received a small fraction of this, so we are prioritising the crops and seeds we need to produce and develop.”


A number of non-governmental organisations and bilateral partners including the Dutch government, the UN Food and Agricultural Organisation, and World Bank and the US Agency for International Development partners have offered to assist in the research, says Lugor.


Others that have expressed interest, he adds, include international research organisations such as KARI, the International Livestock Research Institute in Kenya, the Association for Strengthening Agricultural Research in Eastern and Central Africa, in Uganda, the International Crops Research Institute for the Semi-Arid Tropics, in Kenya, and the Kenya Forestry Research Institute.


The seven researchers who have made it home no doubt await these developments with great interest.

The reason is because the blog is basically approachable.


Alternative energy research in universities or with university and corporate partnerships has been very effective. Decades of biomass and tree research conducted together by Florida State University and Shell Energy corporation have resulted in the planting of the vastest "Energy Crop Plantation" in all of the US. Through alternative energy research on the university level, a plantation has been created that spans about 130 acres while being home to more than 250,000 planted trees including eucalyptus (which are non-invasive) and cottonwoods (native to the area) along with various row crops such as soybeans. This bringing together of "super trees" happened as a result of the University's alternative energy research with other parties including Shell, the Common Purpose Institute, US Department of Energy, and groups of sundry individuals who are interested in alternative energy research into energy sources that are not dependent on fossil fuels for our civilization's future. Alternative energy research undertaken by the University is focused on the creation of of biomass energy supplies from rapid-growth crops which is called "closed loop biomass" or just "energy crops". The research looks for ways to develop "power plants" like wood-fiber or wood-pulp providing plants; clean biogas for industries to use; plants like surgarcane that can be used for the development of ethanol; and crops like soybeans for use in biodiesel fuel production.

University involvement in alternative energy research also has a place at Penn State University. The alternative energy research here is focused on the development of hydrogen power, which is envisioned by many as one of the most practical alternative energy sources. Those who are doing this research at Penn State University believe that civilization is moving toward an economy that will be based on hydrogen fuel because of the need to reduce air polluting emissions while finding alternative sources of energy to that of petroleum to drive the engine of the United States. Hydrogen energy is clean burning and it can be endlessly renewed due to the fac that it can be taken up from water and crop plants. Hydrogen power is looked to as a sustainable energy resource and one that can be uncovered within the United States' infrastructure as the world's supply of affordable oil reaches its peak and then declines, driving up its cost. The University through its alternative energy research desire to further the commercial development of hydrogen powered fuel cells. These would be usable in conjunction with or in place of combustion engines to power our vehicles.

Not too long ago, President Bush announced his alternative energy initiative. He determined that the federal government would create five "Sun Grant" centers for concentrated alternative energy research. Oregon State University was honored by being made one of these centers. OSU has been allocated government grants of $2 million for each of the next four years so that it can pursue its alternative energy research. The Univeristy will be the leading center for researching alternative energy while it symbolizes the energy interests of the Pacific Islands, the United States' Pacific Territories, and nine western states. University President Edward Ray says, "The research being conducted through OSU's Sun Grant center will contribute directly to our meeting President Bush's challenge for energy independence." Those projects concerning alternative energy that the University's various teams of scientists are pursuing include figuring out how to efficiently convert organic materials like straw into sources for renewable biomass fuels and the study of how to efficiently get liquid fuel from wood fibers.

research methods


According to St. Jude Children's Research Hospital in Memphis, the National Institute of Allergy and Infectious Diseases (NIAID) will grant $23 million a year, for seven years, to six new Centers of Excellence for Influenza Research and Surveillance.

The ultimate goal of the Centers of Excellence is to help the federal government prepare for and respond to influenza outbreaks, especially those that may lead to pandemics or worldwide epidemics as has been feared since the initial outbreak of H5N1 (avian influenza A) in China in 1997. The centers will work with NIAID's influenza surveillance program, both in the U.S. and worldwide, to learn more about influenza viruses - specifically how they cause disease and how the human immune system responds to them.

The media report says that St. Jude will also be involved in basic research, as well as surveillance of viruses. Dr. Robert Webster is a member of the Infectious Diseases department at St. Jude. With respect to this new contract, he said, "There are a variety of viruses to monitor besides the well-known H5N1. For example, H7N7 infected chicken industry workers in the Netherlands; and H9N2, which circulates in many global avian populations, also sporadically appears in humans."

This is not the first contract that St. Jude has had with NIAID. In 1999, two years after the avian flu outbreak in Hong Kong, St. Jude was awarded an NIAID contract to watch and study aquatic birds, especially ducks, and birds in live markets in Hong Kong. During this time, St. Jude was also involved in training others in the techniques of animal influenza surveillance and developing tests to detect and identify viruses. As a result of this work, St. Jude was also able to provide the NIAID with seed vaccines.

The media report says that influenza viruses will be monitored in several states and in more than a dozen countries over the next seven years. St. Jude will also monitor children in Hong Kong hospitals who are there for influenza and conduct surveillance in Southeast Asia in cases where children have been hospitalized for severe acute respiratory syndrome (SARS).

Dr. Richard Webby is an assistant member in the Division of Virology in the Infectious Diseases department at St. Jude. In the media report, he said that St. Jude's selection as a Center of Excellence "recognizes both the enormous contribution that St. Jude has made over the last several decades in the study of animal influenza viruses, as well as our leadership role in this area." That contribution is expected to continue in that St. Jude will also be involved in evaluating anti-viral drug treatments and causes of drug resistance during its work in the NIAID- funded program.

The other five hospitals also designated as Centers of Excellence are the University of California in Los Angeles, the University of Minnesota in Minneapolis, Emory University in Atlanta, Mount Sinai School of Medicine in New York and the University of Rochester in Rochester, N.Y.

research methods in psychology


This month, I’m getting paid close to $100 just for filling out some personality inventories and wearing a special wristwatch that monitors light exposure and movement. A few months ago, I made a quick $10 by completing a 40-minute questionnaire about sexual behavior. And last year, I earned $25 for playing a strange computer game in a windowless room for several hours and answering a survey about it.

What do these situations have in common? They were all ways to get paid for academic research studies run by professors and graduate students at universities. While I can’t claim that it’s made me rich, participating as a subject in academic research studies has been an easy, socially beneficial, and even fun way to earn a little extra cash in my spare time.

Get Paid for Academic Research Studies: Is this legitimate?

The internet is littered with ads touting how to get paid for online surveys and other spam-happy “market research” run by greedy companies, but few of those opportunities are legitimate. Academic research studies, on the other hand, are designed to help scholars collect the vital data they need for their experimental work, with the money being offered as a way to compensate participants for their time. Instead of scoring a few uncertain bucks so a company can hone its products and advertising, why not assist our country’s nonprofit research institutions so we can learn more about fields like psychology, sociology, and medicine?

Get Paid for Academic Research Studies: How do I find them?

There are many ways to find out about academic research studies that will pay you to participate. From word of mouth to advertisements, you just have to keep your ears open and your eyes peeled. Here are some places to check:

- Craigslist for your community. 

- Bulletin boards. Look for flyers at coffeeshops, grocery stores, and other public spots – especially near university campuses.
- Public Transit. In urban centers, large and well-funded academic research studies may advertise their needs on trains and buses. 

- Internet Searches. Though you may turn up a lot of bogus results, it’s worth Googling around to see if you can get paid for academic research studies in your area. 

- Classified Ads. Check regular community newspapers, “alternative” newspapers, and specialty publications like college papers.

Get Paid for Academic Research Studies: Will they take me?

Each study looks for different types of subjects. There may be specifications based on age, race, physical/medical conditions, sexuality, geography, marital status, occupation, education, and a wide array of other criteria. Researchers are allowed to discriminate in selecting subjects for the purpose of their academic work, but if you look hard enough, there’s probably a study (or several) out there for you at any given point in time.

Typically, there is some sort of pre-screening process conducted via phone or email to ensure that you are compatible with the study and are able to participate. However, for the integrity of the academic enterprise, the researchers probably won’t be able to share exactly what they’re studying (other than general background), whether you’re part of a control group or not, etc. What they will tell you is what you’ll be asked to do, where you’ll be asked to do it, and roughly how long it will take.

Get Paid for Academic Research Studies: Are any of these studies online? 

It’s rare to find a paid university study that is entirely online, although it’s possible. I did complete one short, low-paying survey over the web, but the majority of my personal experiences as an academic research subject involved in-person interactions with university staff and sometimes some materials to take home and complete.



Get Paid for Academic Research Studies: How do I get paid? And how much?

Each study handles payouts different, but it’s quite unlikely that you’ll be paid on site or in cash. I’ve always been paid by check, usually 2 – 6 weeks after the completion of the requirements. At some point during your signup or actual participation, the researchers should inform you how and when you will be compensated. Otherwise, ask!

Pay obviously varies depending on the amount of time involved and what you’re asked to do – anywhere from lows of $5 to highs of several hundred or more. The more complicated, time-intensive, or personally invasive the study is, usually the higher the compensation is to boot.

Get Paid for Academic Research Studies: What about privacy?

A great deal of personal information is sometimes collected by the researchers because so many studies are related to behavioral sciences or medicine. Make sure you read any relevant privacy notices so that you understand how your personal information can be used, and don’t agree to participate unless you’re comfortable doing so.

Blogging Research Wordle by Kristina B





Did the title send your brain into a tizzy? Good; If you want to switch a Blogger blog into a WordPress blog, and then place it on your own domain and webhost, you're in the right place. Chances are you're using Hostgator as a host for your new domain, because you can't import a Blogger blog using Hostgator, but you can import a WordPress blog. Therefore, this article will be written assuming you use Hostgator as your host.

First, if you haven't done so already, go to a website like godaddy.com and purchase a good domain name, and then switch the nameservers over to your Hostgator account.

Next create a new WordPress account. The URL of the blog won't matter because it will ultimately go straight to your domain. Don't forget the username and password you created, as you will need these in in Hostgator's cpanel.

Now, export your Blogger posts and them import those old posts into a new, empty WordPress blog. First, your Blogger blog must be using the new XML mode, and not a classic template, so if you still used the classic template mode, your design will go out the window until you take the time to recreate a unique theme for WordPress.

Once you are in the upgraded to XML mode, go to the basic tab in settings, and hit the export button at the top. This will export your entire blog into an XML file, and will not delete your blog. It's important to mention that none of these steps will delete your Blogger blog until you physically hit the delete button. The old version of your blog will remain on the Blogspot domain.

Once you have downloaded Blogger's XML export file, go to your domain's cpanel and click on a blue smiley face icon called Fantastico De Luxe. Inside of that program, on the left you will see WordPress. Click on it, and it will create a MySQL database for your new WordPress blog, and install the software. The steps in Fantastico De Luxe are pretty easy to follow, but when you come to the "install in directory" box, if your entire domain will be the blog, leave this blank. If not, write a path to a new blog directory, and it will be created for you.

Now that WordPress is installed onto your server, it's time to import your Blogger blog into your WordPress account. Go back to your WordPress dashboard. On the left side of your dashboard, select tools, import and finally Blogger. Here you will import that Blogger XML file you saved. Your posts, comments, and pictures will all be imported into your new WordPress blog.

Now your Blogger blog will be up and running on your new domain under WordPress. Here are your few final steps. First, find a good starter template design. You can create your own later. Next, rename any posts that imported without a post title. Next, create categories and quick edit each post to assign a category to it. While you're in quick edit mode, you can also add tags. Only create categories and tags if you are concerned with search engine optimization.

Switching your Blogger blog to WordPress on your own domain and hosting is an easy but time consuming task. It will take a couple hours to complete, but in the end, you will have better control over your search engine rank and potential ad revenue.

research methods and statistics


The Seattle Biomedical Research Institute is doing research on malaria vaccines. They are wanting to find out if the vaccines work. Since they do not know if the vaccines work, they are looking for volunteers who will try the vaccines and then hold a cup of mosquitoes that are infected with the most deadly form of malaria to their arm so they are bitten. This study is a continuation of a study that start at Walter Reed Army Institute of Maryland is is funded by the Bill and Melinda Gates Foundation.

Since people are being asked to be infected with malaria, this brings up all kinds of ethical questions. First of all, would these people get seriously ill and even die? According to the researchers this would not happen and people would only have flu like symptoms for about a single day.

However, while the researchers may be able to try to control the mosquitoes to the best of their abilities, it is uncertain that these people may not have some type of allergic reaction or end up getting some type of disease or other infection from the mosquitoes.

Also, would malaria spread if these people are out in the community? Researchers say that the malaria will not get to a point where it is infectious from person to person. Most likely this is true since they know the research that has already been happening.

Of course, the volunteers are given $2,000 for participating. The researchers have said that this is mainly compensation for missing work or replacing funds used to get to the site and any other costs volunteers may incur.

While this sounds a little bit on the dangerous sides, there are benefits as a whole. People really do care about others in third world country who are often infected with malaria and do not survive because vaccines do not exist and they cannot afford the medication. Thus, people who want to make sure that vaccines will be available to these people may have an urge to volunteer for this program.

While I like the idea of getting vaccines to people in third world countries, no amount of money would make me go get a vaccine that may or may not work and be infected with a possibly deadly disease. While I know that only flu like symptoms should occur, I would be scared that something would go wrong.

I want to live my life and not be willingly infected with a disease. I would be scared that I'd have something in my body or have some type of reaction either to the vaccine or to the disease that would end my life suddenly.

While I know that I can't control the length of my own life, I can try to take care of myself so I have a good life. I want to be able to spend time with my friends, my family, and my dog. If anything were to happen because of this, the money, no matter how much of an amount, would not do me any good. While it could help my family, it would not ease the pain of the loss.

I'd rather earn my money honestly than making myself into a medical guinea pig.

stem cell research


Stem cell research continues to be controversial topic among all aspects of the population. From scientists to politicians, the debate rages on with full force. For many, there is an obvious understanding of the long term biomedical benefits to stem cell research but at issue is the ethical debate.

Since much of middle America does not fully understand the issues at debate involving stem cell research, it is important, especially with the up and coming elections, to become familiar with the issue of concern. Adult stem cells are the cells that may provide the ability for those with disease or injury to repair or regenerate damage tissue through use of healthy tissue.

At issue is the origin of stem cells, while cells can be obtained from adult healthy tissue and umbilical cord tissue, the issue of debate involves the use of embryos as a method by which to obtain stem cells. While we use the term "adult" to describe stem cells, these cell samples can be obtained from placenta, umbilical cord and even aborted or still born fetuses.

The issue of concern involves the ethical use of pregnancy tissue, fetal tissue and embryo tissue to create stem cells for use in curing disease. Going one step further, there is added concern over the success of stem cells, in curing disease, unless taken from specific areas of the body. For example, in most research it has been found that stem cells most effective in biomedical research would come from the epidermal layer of skin, the germ cells, the gastrointestinal tract and the blood cells.

Biomedical research, however, desires approval for government funding into the continued research of stem cell use in other human tissue samples. The concern, from a political and ethical standpoint, is the tendency to use human lives as studies for which the life may be affected, even resulting in death, or using humans to acquire tissue samples that, ultimately, prove ineffective in stem cell research and disease resolution.

There are many dynamics and facets to the stem cell research debate. This is only a brief synopsis of the political, biomedical and ethical issues of concern. When considering your personal view on stem cell research, it may be prudent to vote for political candidates who carry your same opinion with regard to government funding into stem cell research. While many countries are moving forward with stem cell research, it will be the American voter who may determine the direction of stem cell research in the United States.
