One third of the work will b e by ex tension courses from the college, carried on either at Camas or otliecr Crown Zellerbach operations or within travel range of the Paper School. Extension work may be in either the major or minor fields of study. Final requirement is three months residence and study on the Oregon State College campus, normally the last third of the degree program.
Kennedy Presents Penn S t a t e Priestley Lectures The 26th annual Priestley lecture series sponsored by Phi Lambda Upsilon at « Pennsylvania State > College; will be pre sented "by Joseph W. Kennedy, chairman of the department of chemistry at Wash ington University. The series of five lec tures i s scheduled for April 21 to 25. Dr. Kennedy's J. W. Kennedy topic i s radioactive atoms and isotopic tracers, and his dis cussions will cover nuclear transforma tions, fission, and transuranium elements,
isotopic tracers and electron transfer reac tions, quantitative kinetic studies with tracers, and self-diffusion of aqueous ions.
starting next fall. The courses lead to the M.A. degree with specialization in physi cal, organic, biochemistry, and analytical chemistry.
Rutgers Expands Evening P r o g r a m in C h e m i s t r y
Glenn T. Seaborg, University of Cali fornia, delivered the annual Phi Lambda Upsilon lecture series at Ohio State Uni versity on March 28 and 29. His subject was the present status of the transuranium elements and nuclear thermodynamics of the heaviest elements.
An evening program in chemistry lead ing to the B.A. degree has been estab lished at Rutgers University. The curricu lum begins in September 1952. Rutgers has offered a series of evening chemistry courses leading to a certificate since 1934 and this program will still be continued. The new program expands these offerings, and follows the regular Rutgers cur riculum. It is expected that a minimum of eight years of evening study will be necessary for completion of the work. Appropriate courses earned previously in the Rutgers evening program may be applied toward the degree. Information regarding regis tration, tuition, and course content will be supplied on request of the registrar, University College, 77 Hamilton St., New Brunswick, N. J.

RESEARCH Bacteria vs. Phenol In Industrial W a s t e An engineering investigation project in the use of biological warfare to combat stream pollution effects of certain indus trial and municipal wastes is being under taken at the Ohio State University engi neering experiment station laboratory under a grant of $10,000 made by the Standard Oil Co. (Ohio). Sohio has established this test project at Ohio State University for an investiga tion of the destruction of phenols in efflu ent water from petroleum refineries. Phenols, it is pointed out, are found in waste water from a number of different industries and also in sanitary sewage from municipalities. When phenols in large quantity are in water, they are toxic to many forms of stream life. The possibility of using biological war fare against phenols is suggested by a surprising strain of bacteria that appear tough enough to destroy these chemicals under carefully controlled conditions. Ohio State University scientists, under the Sohio grant, will explore the possibility of putting such bacteria to work to - destroy the small amounts of phenol in water used in refinery processes.
Research C o r p . G r a n t s A i d Smaller Institutions Grants in aid totaling $875,000 were made by Research Corp. in its 1951 fiscal year. The sum was distributed in trie form of 288 grants to educational and scien tific institutions in 41 states, the District of Columbia, Hawaii, Canada, Formosa, India, Lebanon, and the Philippine Re public. In the annual report covering trie foun dation's 39th year of operation, Joseph W. Barker, president of Research Corp., notes that its fields of disbursement are being strongly influenced by the indirect effects

In the face of this competition, the smaller colleges find it harder and harder to keep together the staffs n e e d e d for science teaching a n d independent research projects, according to Dr. Barker. To support research in such colleges, Research Corp. last year distributed through its Cottrell grants program over $350,000 to the smaller colleges of liberal arts a n d sciences. The principal aim of t h i s pro gram is the s u p p o r t of work by younger researchers a n d teachers w h o are train ing a new generation of scientists. An additional $225,000 was given to universities and scientific institutions through the foundation's General grants program which fosters pioneering research, mainly in the physical sciences.

A general purpose radiation pilot plant is seen in Stanford Research Institute's new radiation engineering laboratory announced recently. The lab will contain the largest source of radioactivity outside of AEC installations—a 50O0-curie source of cobalt 6 0 - a n d will develop and engineer practical safe systems for the use of large amounts of radiations in a wide variety of possible industrial applications. Among promising uses to be investigated soon after the lab begins operation in late spring are nondestructive testing of metal castings and parts by radiography, and cold sterilization of heat-sensitive foods and drugs using gamma radiation. The laboratory's engineering system includes protective devices, remote control equipment and carefully controlled conditions for experimentation, thus reducing to a minimum safety hazards from the highly radioactive cobalt SO source.

Stanley Cohen, instructor at the University of Colorado School of Medicine, has been awarded an American Cancer Society fellowship. The fellowship is for one year, and will enable Dr. Corien to do further research work in the department of radiochemistry at Washington Uni-versity school of medicine, St. Louis, beginning July 1, 1952.
Metallic Aerosol Work at CIcsrkson Chirkson College of Technology has been awarded a Frederick Gardner Cottrell grant of $2000 for the support of Milton Kerker's project entitled: Light Scattering from Metallic Aerosols. An assistant professor of chemistry, Dr. Kerker will use this grant for the purchase of special equipment and the reimbursement of a graduate fellow who will serve as his assistant. It is expected the project will get underway next fall.
