Access to safety results of GM crop field trial tests in India denied to Greenpeace

Even the Right to information act or RTI could not help Greenpeace in India. RTI activists tried using this right for getting information on the safety tests of GM crops but their request was rejected on the plea that disclosure of the information could harm the competitive position of the company developing these crops. Information was sought on the field trial locations and allergenicity and toxicity data related to the rice, brinjal and other crops being tested. Though information on location was revealed but access to other set of information was denied. Greenpeace and other farmer organizations are not satisfied with the manner in which the trials are being conducted and they fear that gross violations have been conducted while conducting the tests. On the other hand GEAC states that field trials were being conducted keeping in view all the biosafety and regulatory norms in mind but it seems that there is something fishy since the government is hiding certain results on pretext of safety. The government should come up with a clear picture or it might become difficult to make the people accept GM crops. Via hindu

IOM Panel Ends California Visit With No Mainstream Media Coverage


The blue-ribbon Institute of Medicine panel examining the performance of the $3 billion California stem cell agency has quietly concluded its first public hearing in California without so much as a smidgen of daily coverage in the mainstream media.

Instead, the big state news in California yesterday was a lawsuit filed by lawmakers against the state's top fiscal officer to prevent him from cutting their pay again when they fail to pass a balanced budget.

It would have been extremely unlikely, however, to have seen any daily coverage of the IOM session. The mainstream media generally ignores the affairs of the California stem cell agency.

Other than what has appeared on the California Stem Cell Report, the most comprehensive look at the $700,000, IOM examination of CIRM was provided on Tuesday by Marcy Darnovsky of the Center for Genetics and Society, which has followed CIRM, and the ballot measure that created it, since 2004.

Darnovsky brought her readers on the Biopolitical Times up to speed on CIRM matters. She noted that CIRM will need more cash in a few years when its bond funding runs out. She concluded,

"But ballot measure or no ballot measure, CIRM will continue to disperse the public money it controls - another billion and a half dollars. This is a public agency spending increasingly scarce public resources. It is funding a field of research in which we place great hopes for medical and scientific advances. These factors make it all the more crucial that CIRM follow the basics of good governance and public accountability, and eschew the hyperbole and exaggerated promises that have tainted stem cell research for so long."

The California Stem Cell Report emailed a 1,370-word statement to the panel. The study director of the IOM panel said the statement would be placed in the panel's record.

The document provided perspective on the formation of CIRM, the political context in which it operates and discussed some of the potential pitfalls of CIRM's necessary but delicate courting of industry. Suggestions were offered for changes to ease potential conflicts of interest and to open to the public the statements of the economic interests of the grant reviewers who make the de facto decisions on CIRM's funding.

Here is the full statement from the California Stem Cell Report.

Magazine Survey on CIRM Shows Mixed Results


The magazine GEN this week produced two relatively lengthy articles dealing with the current state of affairs and the future of the $3 billion California stem cell agency.

Much of the material is familiar to readers of the California Stem Cell Report, but GEN, which says it reaches "221,035 biotech and life science professionals, also produced an online survey that asked its readers: "How helpful has CIRM been in advancing stem cell science?"

At the time of this writing, the results showed that 40.9 of respondents said CIRM was "very helpful."  An identical percentage said "not very" or were undecided. The survey showed 18.2 percent as ranking the agency "somewhat" helpful. The number of respondents was not disclosed.

The two articles (see here and here)by Alex Philippidis also discussed the possibility of a bond issue in a "few years," before CIRM runs out of cash in 2017. Philippidis wrote,

"By then CIRM hopes to have won what ICOC (the CIRM governing board) chairman Jonathan Thomas, Ph.D., has called the 'communications war' the agency is fighting with California newspapers and the CIRM-focused blog California Stem Cell Report. Both have criticized the agency over a host of governance and pay issues."

For the record, the California Stem Cell Report has not criticized the agency in connection with the level of its executive pay. We have pointed out that many California voters have a highly negative and visceral reaction to high public salaries, which is a matter that CIRM must deal with in connection with retention of public confidence. We have also noted that the salaries represent a tiny, tiny fraction of CIRM spending.

The California Stem Cell Agency and the ACT Opportunity


A promising, positive story on stem cell research in California popped up in the news this week, involving improvements in vision as the result of the only hESC clinical trial in the nation.

The story came after Jonathan Thomas, chairman of the $3 billion California stem cell agency, said in the San Francisco Business Times that what he likes least about his job is that "the coverage in the press chooses to focus on items besides the extraordinary work that our scientists are doing."

The good news about the eye research appeared in the New York Times, Los Angeles Times and across the nation. However, it did not involve work at the stem cell agency, probably for reasons that likely have to do in good part with CIRM. The research involves a firm headquartered in Santa Monica, Ca., Advanced Cell Technology, that moved its base to the Golden State in hopes of securing CIRM funding. ACT has applied more than once for CIRM cash but has never received a grant. And it is one of the rare companies that has complained publicly to the CIRM governing board about a conflict of interest on the part of a CIRM reviewer. In ACT's case, its complaints received a public brushoff at a CIRM board meeting in 2008.

ACT's results in its clinical trial are quite tentative. They involve only two persons. One of the UCLA scientists involved said part of the results could have been the result of a placebo effect. Nonetheless, the reports carried the kind of story line that CIRM yearns for. Indeed, Thomas stressed the need for positive news when he told CIRM directors last June that the agency is in a "communications war" that is tied to its ultimate fate. (The agency runs out of cash in 2017.)

The New York Times' Andy Pollock wrote,

"Both patients, who were legally blind, said in interviews that they had gains in eyesight that were meaningful for them. One said she could see colors better and was able to thread a needle and sew on a button for the first time in years. The other said she was able to navigate a shopping mall by herself."

On its research blog, CIRM described the ACT results as a "milestone." CIRM's Amy Adams wrote,

"It’s the first published paper showing that—at least in this small number of patients for the first few months—the cells are safe."

She quoted Hank Greely of Stanford as saying that the news from ACT is "at least, a little exciting – and in a field that saw its first approved clinical trial stopped two months ago, even a little exciting news is very welcome."

Greely's reference, of course, was to Geron's sudden abandonment in November of its hESC trial, only three months after CIRM gave the firm a $25 million loan. It was widely believed that ACT was one of the initial applicants in the round that provided funding for Geron, although CIRM does not release the names of non-funded applicants.

Last week, CIRM directors spent a fair amount of time discussing the agency's future. The talk was of priorities, hard choices and generating results that would resonate with the people of California.

This week's news from a company that was not funded by CIRM will give them more to ponder.

Kansas City Math Tutor

Kansas City Math Tutor

Kansas City Math TutorMy name is Zachary. My interest in tutoring started when I was a middle school student myself, helping a few classmates study for tests or cram for the state-required evaluations. When I was in high school, I started tutoring students in Algebra, Geometry, and Calculus I for cash, and quickly found I could make good money tutoring a wide range of subjects. I obtained my undergraduate degree from Baker University in Psychology, while continuing to tutor in increasing subject areas like English, biology, chemistry and philosophy. My graduate degree is a Master's of Science in Experimental Psychology, which was a statistics-heavy degree path.

When I tutor, I like to first discover how students are most comfortable learning. Psychology has long held that multiple learning styles exist, and while debate continues to rage over which style is best I prefer to think of each style as having its own strengths and drawbacks. However, I have learned to teach to many different styles, and can teach contextually, rote, test-oriented or experience-based lessons. I am also comfortable with group tutoring, having led several classes of students in graduate school.

Studio City Science Tutor

Hello All!

Studio City Schience TutorI've passed CBEST (the test teachers take to get licensed in California), CSET General Science subject tests, and also the CSET Biology and Chemistry subtests. I graduated from college summa cum laude with a 3.9 GPA. I received a Bachelor of Science in Biology, with a Psychology minor. I achieved a lot of advanced, in-depth science knowledge from attending medical school. In any case, the strength of a good tutor lies not only in mastering the knowledge, but in also being able to deliver it to the student effectively. I've been told by my students that I am a pro at this! If you let me tutor you, I guarantee that you will truly understand the material better. Also, I have a magnetic personality, so I guarantee that you will have a lot of fun during our tutoring sessions!

One of my strengths as a tutor lies in the fact that I am very versatile, both in terms of the age groups I can work with, and the subjects I can teach. This versatility is actually what I enjoy most about my tutoring experiences. Currently, I am working with students in elementary school, high school, college and also graduate school. Some of the subjects I teach include Algebra, Biology, Chemistry, Physiology, Biochemistry and English. I am also tutoring a number of students in SAT, ACT, ISEE, and SSAT prep.

A Counterpoint to the Concept of the Late Life Mortality Plateau

Last week I posted on what seems to be the strikingly different nature of aging at very advanced ages. For example, there is what is known as the mortality plateau in very late life, a period in which mortality rates stop increasing. This has been studied in flies, and there is a small amount of evidence that suggests it might also exist in humans. But I thought I'd point you in the opposite direction today. The research partnership of Leonid Gavrilov and Natalia Gavrilova published a study on mortality at advanced ages not so very long ago, and their data suggests that there is no mortality plateau for humans. The link below is a PDF version of the paper:

Mortality measurement at advanced ages: A study of the Social Security Administration Death Master File

Accurate estimates of mortality at advanced ages are essential to improving forecasts of mortality and the population size of the oldest old age group. However, estimation of hazard rates at extremely old ages poses serious challenges to researchers: (1) The observed mortality deceleration may be at least partially an artifact of mixing different birth cohorts with different mortality (heterogeneity effect); (2) standard assumptions of hazard rate estimates may be invalid when risk of death is extremely high at old ages and (3) ages of very old people may be exaggerated.

One way of obtaining estimates of mortality at extreme ages is to pool together international records of persons surviving to extreme ages with subsequent efforts of strict age validation. This approach helps researchers to resolve the third of the above-mentioned problems but does not resolve the first two problems because of inevitable data heterogeneity when data for people belonging to different birth cohorts and countries are pooled together. In this paper we propose an alternative approach, which gives an opportunity to resolve the first two problems by compiling data for more homogeneous single-year birth cohorts with hazard rates measured at narrow (monthly) age intervals.

...

Study of several single-year extinct birth cohorts shows that mortality trajectory at advanced ages follows the Gompertz law up to the ages 102-105 years without a noticeable deceleration. Earlier reports of mortality deceleration (deviation of mortality from the Gompertz law) at ages below 100 appear to be artifacts of mixing together several birth cohorts with different mortality levels and using cross-sectional instead of cohort data. Age exaggeration and crude assumptions applied to mortality estimates at advanced ages may also contribute to mortality underestimation at very advanced ages.

All the more reason to work harder on the development of rejuvenation biotechnology, capable of repairing the damage of aging. Time waits for no one.

Genetic Signatures of Exceptional Longevity in Humans

A bold set of claims from this group working on the genetics of natural variation in longevity for humans: "Like most complex phenotypes, exceptional longevity is thought to reflect a combined influence of environmental (e.g., lifestyle choices, where we live) and genetic factors. To explore the genetic contribution, we undertook a genome-wide association study of exceptional longevity in 801 centenarians (median age at death 104 years) and 914 genetically matched healthy controls. Using these data, we built a genetic model that includes 281 single nucleotide polymorphisms (SNPs) ... Consistent with the hypothesis that the genetic contribution is largest with the oldest ages, the sensitivity of the model increased in the independent cohort with older and older ages ... Further [analysis] suggests that 90% of centenarians can be grouped into clusters characterized by different 'genetic signatures' of varying predictive values for exceptional longevity. ... The different signatures may help dissect this complex phenotype into sub-phenotypes of exceptional longevity." The researchers are claiming some moderately common sets of SNPs found in centenarians (but not so common in the general population) can predict exceptional longevity with odds of 70% or higher, with the much more predictive combinations of SNPs - some at 95% odds of exceptional longevity - being correspondingly very rare. The caveat here is that this is heavily statistical work, and we've already seen one paper from this group withdrawn last year for issues with the statistics.
