Stockholders' Equity Note Disclosure [Text Block] | 6. EQUITY TRANSACTIONS 2003 CONSULTANT STOCK PLAN In August 2003, we adopted the 2003 Consultant Stock Plan (the "Stock Plan"), which provides for grants of common stock through August 2013, to assist us in obtaining and retaining the services of persons providing consulting services. A total of 1,000,000 common shares were initially reserved for issuance under the Stock Plan. On March 29, 2004, we filed a registration statement on Form S-8 for the purpose of registering 1,000,000 common shares issuable under the Stock Plan under the Securities Act of 1933. On August 29, 2005, we filed a Form S-8 for the purpose of registering an additional 2,000,000 shares, for a total of 3,000,000 common shares reserved under the Plan.

On February 17, 2010, we filed a Form S-8 for the purpose of registering an additional 1,500,000 shares, for a total of 7,500,000 common shares reserved under the Plan. 2005 DIRECTORS COMPENSATION PROGRAM Upon the recommendation of our Compensation Committee, in February 2005, we adopted our 2005 Directors Compensation Program (the "Directors Compensation Program") which advances our interests by helping us to obtain and retain the services of outside directors upon whose judgment, initiative, efforts and/or services we are substantially dependent, by offering to or providing those persons with incentives or inducements affording them an opportunity to become owners of our capital stock. Under the Directors Compensation Program, a newly elected director will receive a one-time grant of a non-qualified stock option of 1.5% of the common stock outstanding at the time of election. The options will vest one-third at the time of election to the Board and the remaining two-thirds will vest equally at year end over three years. Additionally, each director will also receive an annual $25,000 non-qualified stock option retainer, $15,000 of which is to be paid at the first of the year to all directors who are on the Board prior to the first meeting of the year and a $10,000 retainer will be paid if a director attends 75% of the meetings either in person, via conference call or other electronic means. The exercise price for the options under the Directors Compensation Program will equal the average closing of the last ten (10) trading days prior to the date earned. At March 31, 2012 under the 2005 Directors Compensation Program we had issued 1,337,825 options to outside directors and 3,965,450 options to employee-directors for an aggregate grant amount of $5,303,275. Of those grants, 514,550 outside directors’ options had been forfeited, 867,175 employee-director’s options had been forfeited, 250,000 outside directors’ options had been exercised and 3,671,550 options remained outstanding. 2010 STOCK INCENTIVE PLAN In August 2010, we adopted the 2010 Stock Incentive Plan (the "Incentive Plan"), which provides incentives to attract, retain and motivate employees and directors whose present and potential contributions are important to the success of the Company by offering them an opportunity to participate in our future performance through awards of options, the right to purchase common stock, stock bonuses and stock appreciation rights and other awards. A total of 3,500,000 common shares were initially reserved for issuance under the Incentive Plan. In August 2010, we filed a registration statement on Form S-8 for the purpose of registering 3,500,000 common shares issuable under the Incentive Plan under the Securities Act of 1933. At March 31, 2012 we did not have any shares remaining under either the 2003 Consultant Stock Plan or the 2010 Stock Incentive Plan.

On March 29, 2012, we entered into a unit subscription agreement (the "Subscription Agreement") with one accredited investor (the “Purchaser”) pursuant to which the Purchaser purchased an aggregate of $300,000 (the "Subscription Amount") of units (the "Units" and each a "Unit"), with each Unit consisting of (i) one share of Common Stock, par value $0.001 per share (the “Common Stock”) at a price per share of $0.08, of the Registrant and (ii) a warrant to purchase such number of shares of Common Stock of the Company as shall equal (a) fifty percent of the Subscription Amount divided by (b) $0.08 (the "Warrant Shares") at an exercise price of $0.125 per Warrant Share, (each, a “Warrant” and collectively, the “Warrants”). Based on the foregoing, Units consisting of 3,750,000 shares of Common Stock and Warrants to purchase 1,875,000 shares of Common Stock were issued. The Warrants are exercisable for a period of seven years from the date of issuance at a exercise price of $0.125, subject to adjustments for stock splits, stock dividends, recapitalizations and the like. The Purchaser may exercise the Warrant on a cashless basis if the shares of common stock underlying the Warrant are not then registered pursuant to an effective registration statement. In the event the Purchaser exercises the Warrant on a cashless basis, we will not receive any proceeds. There are no registration rights with respect to the Warrants or the Warrant Shares. In March 2012, we entered into a consulting agreement with Catalyst Financial Resources to provide corporate communications and media relations services. The term of the agreement is twelve months although it can be terminated by either party. The agreement calls for monthly compensation of $12,500 comprised of $7,500 in cash and $5,000 in either notes or common stock. WARRANTS Fiscal Year Ended March 31, 2011: In April 2010, we entered into a one year consulting agreement with an individual for media relations services. We agreed to pay the consultant 22,727 warrants to purchase our common stock at a fixed exercise price of $0.33 per share on a monthly basis. The agreement values these warrant issuances at $5,000 per month. Through March 31, 2011, we have recorded warrants to purchase 249,997 shares of our stock per this agreement. In April 2010, we raised $75,000 from the sale to an accredited investor of a 10% convertible note. The convertible note matures in October 2011 and is convertible into our common stock at a fixed conversion price of $0.25 per share prior to maturity. The investor also received three year warrants to purchase 300,000 unregistered shares of our common stock at a price of $0.25 per share. In May 2010, a warrant holder exercised warrants to purchase 1,599,348 shares of common stock at the agreed exercise prices, which resulted in proceeds of $283,600. As an inducement to this warrant holder, we agreed to issue to him 1,599,348 replacement warrants on the same terms as the warrants that he exercised. In June 2010, we issued 1,586,040 shares of restricted common stock and 2,981,598 warrants to purchase our common stock at a price of $0.20 per share to the holders of our Amended and Restated Series A 12% Convertible Notes and to their law firm. 1,586,040 of those warrants were issued as a Unit payment of accrued and prepaid interest and liquidated damages (see Note 5). In July 2010, we entered into a Note and Warrant Purchase Agreement (the "Purchase Agreement") with Tonaquint, Inc., a Utah corporation (the "Investor") whereby we issued and sold, and the Investor purchased: (i) a Convertible Promissory Note of the Company in the principal amount of $890,000 (the "Company Note") and (ii) a Warrant to purchase common stock of the Company (the "Warrant").

In September 2010, we entered into a Subscription Agreement with three accredited investors (the “Purchasers”) providing for the issuance and sale of convertible promissory notes and corresponding warrants in the aggregate principal amount of $1,430,000. The initial closing under the Subscription Agreement resulted in the issuance and sale of (i) convertible promissory notes in the aggregate principal amount of $743,600, (ii) five-year warrants to purchase an aggregate of 3,718,000 shares of our common stock at an exercise price of $0.31125 per share, and (iii) five-year warrants to purchase an aggregate of 3,718,000 shares of our common stock at an exercise price of $0.43575 per share. In November 2010, as part of a settlement agreement involving our February 2010 Convertible Note(see Note 5) we issued warrants to purchase 2,727,272 shares of common stock in exchange for the return and cancellation of a warrant to purchase 660,000 shares of common stock. In November 2010, five noteholders of our May & June 2009 10% Convertible Notes (see Note 5) elected to convert $100,000 of principal and $15,039 of accrued interest to common stock at the agreed conversion price of $0.20 per share. As a result of those conversions, we issued those noteholders warrants to purchase 500,000 shares of common stock at the agreed exercise price of $0.20 per share. Fiscal Year Ended March 31, 2012: In April 2011, we entered into a Subscription Agreement with two accredited investors (the “Purchasers”) providing for the issuance and sale of convertible promissory notes and corresponding warrants in the aggregate principal amount of $385,000. The closing under the Subscription Agreement resulted in the issuance and sale by us of (i) convertible promissory notes in the aggregate principal amount of $385,000, (ii) five-year warrants to purchase an aggregate of 4,004,000 shares of our common stock at an exercise price of $0.125 per share, and (iii) five-year warrants to purchase an aggregate of 4,004,000 shares of our common stock at an exercise price of $0.175 per share.

These warrants were issued as an antidilution adjustment under certain common stock purchase warrants held by Purchasers that were acquired from us in September 2010. In May 2011, we agreed to modify three warrants held by an institutional investor as the result of antidilution protection. In July and August 2011, we raised $357,656 in 10% convertible notes. Those notes had a fixed conversion price of $0.09 per share and carried an interest rate of 10%. The convertible notes mature in July and August 2012. We also issued those investors five year warrants to purchase 3,973,957 shares of common stock at $0.125 per share. On September 23, 2011, we entered into a Subscription Agreement with two accredited investors (the “Purchasers”) providing for the issuance and sale of convertible promissory notes and corresponding warrants in the aggregate principal amount of $253,760. The warrants carried a five-year term to purchase an aggregate of 3,625,143 shares of our common stock at an exercise price of $0.10 per share. There are no registration requirements with respect to the shares of common stock underlying the notes or the warrants. In November 2011, we raised $525,000 in 5% Original Issue Discount Unsecured Convertible Debentures from five accredited investors pursuant to which the investors purchased an aggregate principal amount of $525,000 for an aggregate purchase price of $500,000. The debentures bear interest at 20% per annum and mature on April 20, 2012. The debentures will be convertible at the option of the holders at any time into shares of our common stock, at a conversion price equal to $0.0779, subject to adjustment. In connection with the debentures, the purchasers received warrants to purchase 3,369,706 shares of our Common Stock. The warrants are exercisable for a period of five years from the date of issuance at an exercise price of $0.11, subject to adjustment. In February 2012, we raised $525,000 in 5% Original Issue Discount Unsecured Convertible Debentures from five accredited investors pursuant to which the investors purchased an aggregate principal amount of $525,000 for an aggregate purchase price of $500,000. The debentures bear interest at 20% per annum and mature on April 20, 2012. These subscriptions represent the completion of the $1,000,000 securities offering that was initiated and priced in November 2011. In connection with the subscription agreement, the investors received warrants to purchase 3,369,707 shares of our common stock. The warrants are exercisable for a period of five years from the date of issuance at an exercise price of $0.11 per share, subject to adjustment. On March 29, 2012, we entered into a unit subscription agreement (the "Subscription Agreement") with one accredited investor (the “Purchaser”) pursuant to which the Purchaser purchased an aggregate of $300,000 (the "Subscription Amount") of units (the "Units" and each a "Unit"), with each Unit consisting of (i) one share of Common Stock, par value $0.001 per share (the “Common Stock”) at a price per share of $0.08, of the Registrant and (ii) a warrant to purchase such number of shares of Common Stock of the Company as shall equal (a) fifty percent of the Subscription Amount divided by (b) $0.08 (the "Warrant Shares") at an exercise price of $0.125 per Warrant Share, (each, a “Warrant” and collectively, the “Warrants”). Based on the foregoing, Units consisting of 3,750,000 shares of Common Stock and Warrants to purchase 1,875,000 shares of Common Stock were issued. The Warrants are exercisable for a period of seven years from the date of issuance at a exercise price of $0.125, subject to adjustments for stock splits, stock dividends, recapitalizations and the like. The Purchaser may exercise the Warrant on a cashless basis if the shares of common stock underlying the Warrant are not then registered pursuant to an effective registration statement. In the event the Purchaser exercises the Warrant on a cashless basis, we will not receive any proceeds. There are no registration rights with respect to the Warrants or the Warrant Shares. During the fiscal year ended March 31, 2012, we issued 3,699,914 shares of restricted common stock related to net warrant cashless exercises. On March 31, 2012, we agreed to extend by two years the expiration date of seven warrants for a total of 2,480,000 shares held by a note holder and to reduce the exercise price on those warrants from $0.25 per share on six of the warrants and $0.19 on the seventh warrant to $0.125 per share in exchange for his extension of $50,000 of the October & November 2009 10% Convertible Notes and the $75,000 April 2010 10% Convertible Note by that same two year period. We recorded a charge of $104,196 relating to this modification. A summary of the aggregate warrant activity for the years ended March 31, 2012 and 2011 is presented below:

OPTIONS At March 31, 2012, we had issued 1,337,825 options to outside directors and 3,965,450 options to employee-directors under the 2005 Directors Compensation Program. Of the options issued to employee-directors, 867,175 had expired. Of the options issued to outside directors, 519,417 options had expired or been forfeited, 250,000 options had been exercised and 3,666,683 options remain outstanding. From time to time, our Board of Directors grants common share purchase options or warrants to selected directors, officers, employees, consultants and advisors in payment of goods or services provided by such persons on a stand-alone basis outside of any of our formal stock plans. The terms of these grants are individually negotiated. In August 2000, we adopted the 2000 Stock Option Plan ("Stock Option Plan"), which was approved by its stockholders in September 2000. The Stock Option Plan provides for the issuance of up to 500,000 options to purchase shares of common stock. Such options can be incentive options or nonstatutory options, and may be granted to employees, directors and consultants. The Stock Option Plan has limits as to the eligibility of those stockholders who own more than 10% of our stock, as defined. The options granted pursuant to the Stock Option Plan may have exercise prices of no less than 100% of fair market value of our common stock at the date of grant (incentive options), or no less than 75% of fair market value of such stock at the date of grant (nonstatutory). At March 31, 2012, we had granted 47,500 options under the 2000 Stock Option Plan of which all 47,500 have been forfeited and also granted 10,000 shares to employees under the plan, with 457,500 available for future issuance. On March 26, 2012, Mr. Joyce entered into an Option Suspension Agreement whereby Mr. Joyce agreed not to exercise his stock options pending the filing of amended Articles of Incorporation of the Company increasing our authorized capital. Accordingly, none of Mr. Joyce’s options can be exercised until the amended Articles of Incorporation have been filed. Those amended Articles of Incorporation were filed on June 4, 2012. On March 26, 2012, Mr. Frakes entered into an Option Suspension Agreement whereby Mr. Frakes agreed not to exercise his stock options pending the filing of amended Articles of Incorporation of the Company increasing our authorized capital. Accordingly, none of Mr. Frakes’ options can be exercised until the amended Articles of Incorporation have been filed. Those amended Articles of Incorporation were filed on June 4, 2012. On May 21, 2010, the Board of Directors of the Company amended the expiration terms of certain outstanding stock options such that all outstanding stock options of the Company shall have a term that is for not less than ten (10) years following the original date of grant. No other terms or features of the stock options were modified or amended. Stock options held by Mr. James Joyce, our Chief Executive Officer and Chairman of the Board of Directors, Dr. Richard Tullis, our Chief Science Officer and member of the Board of Directors, Mr. Franklyn Barry, a member of the Board of Directors, and Mr. Edward Broenniman, a member of the Board of Directors, were modified accordingly. Of the foregoing (i) options to purchase 2,231,100 shares held by Mr. Joyce were extended to February 23, 2015; (ii) options to purchase 867,175 shares held by Dr. Tullis were extended to February 23, 2015; (iii) options to purchase 308,725 shares held by Mr. Broenniman were extended to February 23, 2015; and (iv) options to purchase 264,550 shares held by Mr. Barry were extended to February 23, 2015. All of the foregoing options are at an exercise price of $0.38 per share. The foregoing represents only a portion of the total options and shares owned by our directors and officers. This option extension resulted in an additional charge of $491,377 in the fiscal year ended March 31, 2011 based upon the change in the fair value resulting from the extension to the term of the options based upon the binomial lattice option valuation model. On September 27, 2010, our Board of Directors granted the following stock options, all with an exercise price of $0.25 per share, the closing price of our common stock on that date: To our CEO, a ten year option to acquire an aggregate of 2,500,000 shares of our common stock. The option vested as to 1,000,000 shares on the grant date and will vest as to the remaining 1,500,000 shares one-third each year over three years on each anniversary of the grant date. To our CSO, a ten year option to acquire an aggregate of 1,000,000 shares of our common stock. The option vested as to 500,000 shares on the grant date and vested as to the remaining 500,000 shares one year from the grant date. To Mr. Franklyn S.
