Photosynthetic Harvest Inc. Harnesses The Power Of Nature's Chemical Factories By "Milking" Green Plants For Valuable Natural Products
Our novel biotechnology enables us to literally tap a billion years worth of chemical synthesis capabilities hidden within the genetic systems of green plants to pose new options to emerging problems such as multi-drug resistant microbes, pesticide resistant insects, and cancers that are non- responsive to existing therapies.

USDA Researchers Prepare A New Trap For The Potato Beetle
The strong smell of new-mown grass - or other damaged plants - includes chemicals that attract plant-eating insects.

Vitamin C May Reduce Angina, Heart Attack Risks
Moderate daily supplements of vitamin C taken by people with coronary artery disease may be effective in improving the function of blood vessels, preventing the chest pains of unstable angina pectoris and reducing the risk of heart attack and stroke, three recent studies suggest.

Intestinal Bug Likely Killed Alexander The Great
Alexander the Great, who ruled much of the ancient world until his death in 323 B.C., was conquered at age 32 not by an enemy, but possibly by a tiny intestinal bug.

Adult Mouse Blood Cell Types Rejuvenated Through Injection Into The Early Embryonic Environment
Contrary to accepted ideas, scientists from the Max Planck Institute of Immunobiology and the University of Freiburg have found that blood stem cells from adult mice can survive in the very different environment of the early embryo and even go on to produce blood cells reprogrammed to have embryonic features (Cell, June 12, 1998).

Asking Patients To Give Up Smoking Isn't Effective
Christopher Butler et al write that most people are aware of the negative effects of smoking and that they believe that it should be up to them whether they give up or not.

DFG To Set Up 14 New Collaborative Research Centres
On July the Deutsche Forschungsgemeinschaft (DFG) will set up 14 new collaborative research centres and two new transfer centres.

Deterioration Of Sleep During Middle Age Related To Changes In The Biological Clock, Say Pitt Researchers
In one of the first studies of its kind, sleep researchers at the University of Pittsburgh have learned that quality of sleep begins to deteriorate during what many consider the most productive years -- middle age -- much earlier than previously thought

HRT And It's Role In Preventing Hip Fractures
Karl Michaƫlsson et al from Sweden suggest that substantial hip fracture protection can exist if women are taking HRT or have done so recently with the greatest gain found in those women who have been taking it for a long period of time.

About The Care Of Patients Before They Are Admitted To Intensive Care
Peter McQuillan et al from intensive care units in the UK found that 54 of the 100 patients received suboptimal care and nearly half of these patients died.

Report Focuses On Managed Care Impact In Clinical Microbiology Labs
Increasing pressures to use lesser-trained workers in clinical microbiology laboratories and to employ short-cut methods can lead to compromises in the quality of microbiological analysis and detract from optimal patient care unless preventive steps are taken, warns a report issued by the American Academy of Microbiology.

Virginia Tech Biologists' Discoveries Could Help Target Cancer Treatment
Johnson & Johnson Corp. and the Janssen Research Foundation have awarded a team of Virginia Tech biologists a grant to pursue new discoveries regarding the chemistry that initiates cell differentiation.
