Double identities lie behind chromosome disorders
Chromosome disorders in sex cells cause infertility, miscarriage and irregular numbers of chromosomes (aneuploidy) in neonates.

Children's scientists discover fundamental protein instrumental to brain development and repair
Scientists at Children's National Medical Center have demonstrated conclusively that a specific protein and its signaling activity are instrumental in myelination and remyelination, processes essential to the creation and repair of the brain's white matter.

Biocontrol of invasive water hyacinth contributes to socioeconomic and health improvements in Africa
In research that will be presented at the annual meeting of the American Society of Plant Biologists in Chicago (July 7-11, 2007), scientists implemented a successful bioeradication program of an invasive water weed in Africa's Lake Victoria.

Study identifies a common genetic risk factor for colorectal and prostate cancer
A study led by researchers at the Keck School of Medicine of the University of Southern California has found that one of seven genetic risk factors previously identified as increasing the probability of developing prostate cancer also increases the probability of developing colorectal cancer.

Climate change reduces Queensland's bat numbers
A central eastern Queensland mine has turned up bat fossils which show climate change has had a negative impact on the state's bat population.

Pumpkin: A fairytale end to insulin injections?
Compounds found in pumpkin could potentially replace or at least drastically reduce the daily insulin injections that so many diabetics currently have to endure.

First all-African produced genetically engineered maize is resistant to maize streak virus
In research that will be presented at the annual meeting of the American Society of Plant Biologists in Chicago (July 7-11, 2007), South African scientists developed a transgenic maize variety resistant to maize streak virus.

Size and positioning of floral anthers facilitates
In their work, Dr. Peter Endress and his colleagues found that the sizes and positioning of the anthers facilitates pollen collection by buzz-pollinating bees.

An international group of Alzheimer's disease (AD) experts have proposed new criteria for the reasearch diagnosis of the condition, as they argue the existing criteria are out of date due to unprecedented growth of scientific knowledge in the field.

Include children in research to make breakthroughs in child medicine, says expert
Scientists will only make real breakthroughs in children's medicine if they include children in research programmes as well as adults, according to a leading paediatric expert.

Discovery about obesity drug helping scientists develop new cancer treatments
Based on their surprising discovery that an obesity drug can kill cancer cells, scientists at Wake Forest University School of Medicine have made a new finding about the drug's effects and are working to design more potent cancer treatments.

U-M, Israeli scientists report major advance in search for genes associated with colon cancer
An international team of researchers is reporting on a 10-year study of colon cancer among Israeli Jews and Arabs.

Rapid evolution of defense genes in plants may produce hybrid incompatibility
Species are kept separate in plants and animals through barriers to gene flow.

Hormone inhibitor promising for hard-to-treat prostate cancer
For prostate cancer patients whose tumors have continued to grow despite medical or surgical castration, a new drug candidate that inhibits production of male hormones anywhere in the body is showing promise in early trials.
