History and timing of human impact on Lake Victoria, East Africa
Lake Victoria, the world's largest tropical lake, suffers from severe eutrophication and the probable extinction of up to half its 500+ species of endemic cichlid fishes. New sediment-core data show that increased algal production developed from the 1930s onwards, paralleling human population growth and agricultural activity in the surrounding... view more...

Significant differences in growth of male and female embryos after ICSI
There is a clear difference in growth rate between male and female pre-implantation embryos created by ICSI, but not after IVF, a scientist said today at the 20th annual conference of the European Society of Human Reproduction and Embryology. Dr John Dumoulin, of the Academic Hospital Maastricht, Maastricht, The Netherlands told... view more... (2004-06-29)
New inhibitor has potential as cancer drug
Laboratory experiments have previously shown that cancer cells overproduce an enzyme, heparanase, which splits the body's own polysaccharide heparan sulfate into shorter fragments. view more (2007-10-23)
A new take on growth factor signaling in tamoxifen resistance
Differences in growth factor (GF) signaling may cause the poor prognosis in some breast cancer cases. A new study, published in the open access journal BMC Medical Genomics, suggests that some estrogen receptor-positive breast cancers respond poorly to tamoxifen because of increased GF signaling. view more (2009-06-24)
Effective pain treatment for cancer patients?
Cancer patients often suffer from severe pain that cannot be effectively treated with conventional medication. view more (2009-06-26)
tTGA: Is it more essential in diagnosis of gluten sensitive enteropathy?
CD is a highly prevalent disease (1:100 to 1:300) which fulfils most of the criteria favoring mass screening. Despite this, screening for gluten sensitive enteropathy (GSE) is still controversial due to its dubious benefits and the acceptance of a gluten-free diet (GFD). view more (2009-03-24)
Honey-bee products in cancer treatment and prevention
Natural honey-bee products such as propolis, royal jelly, caffeic acid, honey and venom may have applications in cancer treatment and prevention, say Croatian researchers in Journal of the Science of Food and Agriculture this month. view more (2004-12-02)
Model for new generation of blood vessels challenged
In-growth and new generation of blood vessels, which must take place if a wound is to heal or a tumor is to grow, have been thought to occur through a branching and further growth of a vessel against a chemical gradient of growth factors. view more (2009-06-02)
New research shows climate change triggers wars and population decline
Climate change may be one of the most significant threats facing humankind. A new study shows that long-term climate change may ultimately lead to wars and population decline. view more (2007-11-26)
CHECKING HOW CELLS GROW: New research dismisses a widely held assumption about cell growth
Research published today in Journal of Biology challenges an assumption about cell growth that underpins modern cellular biology. Ian Conlon and Martin Raff, of University College London, show that mammalian cells do not regulate their size in the way scientists have assumed they do since the 1970s. Conlon and Raff conducted a series of... view more... (2003-04-23)
First evidence of gene therapy for abnormal blood vessel growth in newborns
The first evidence of the potential for gene therapy to treat eye disease that stems from abnormal blood vessel growth is revealed in research published in the British Journal of Ophthalmology. Gene therapy is a relatively new and much heralded therapeutic approach. But despite the advances in molecular genetics, attempts to target organs or... view more... (2001-07-18)
'Mighty mice' made mightier
The Johns Hopkins scientist who first showed that the absence of the protein myostatin leads to oversized muscles in mice and men has now found a second protein, follistatin, whose overproduction in mice lacking myostatin doubles the muscle-building effect. view more (2007-08-29)
Simple explanation for complex pattern of feather development
Biologists testing a mathematical model of the mechanism birds use to control the growth of complex feathers found that plumed feather structures involve the coordination of at least two genes that activate and that inhibit barb growth. view more (2005-08-16)
Blue light used to harden tooth fillings stunts tumor growth
A blue curing light used to harden dental fillings also may stunt tumor growth, Medical College of Georgia researchers say. view more (2008-06-25)
Drug therapy reduces neuroblastoma tumor growth in pre-clinical investigation
Researchers from the Children's Cancer Hospital at The University of Texas M. D. Anderson Cancer Center have discovered a new drug combination that significantly hinders tumor growth in neuroblastoma, a childhood cancer. view more (2009-04-27)
Tiny 'housekeeper' crabs help prevent coral death in South Pacific
Tiny crabs that live in South Pacific coral help to prevent the coral from dying by providing regular cleaning "services" that may be critical to the life of coral reefs around the world, according to scientists from the University of California, Santa Barbara. view more (2006-10-24)
Jefferson researchers uncover new evidence of prolactin's possible role in breast cancer
Scientists at the Kimmel Cancer Center at Jefferson in Philadelphia have discovered new molecular evidence of the role of the hormone prolactin in breast cancer. view more (2007-10-01)
New method to inhibit growth of tumor cells
A new and promising way to inhibit the growth of tumor cells is the result of a collaborative effort between researchers Lars-Ã"¦ke Fransson and Mattias Belting at Lund University and a team in La Jolla, USA, led by cancer researcher Jeffrey Esko. Their work involves hampering the production of two substances that help tumor cells to grow... view more... (2001-12-21)
Mathematics reveals genetic pattern of tumor growth
Using mathematical theory, UC Irvine scientists have shed light on one of cancer's most troubling puzzles - how cancer cells can alter their own genetic makeup to accelerate tumor growth. view more (2007-06-25)
Experiments point to new treatments for PKD
A family of small molecules called CFTR inhibitors show promising effects in slowing the progression of polycystic kidney disease (PKD), the most common genetic disease of the kidneys, according to preliminary research reported in the July 2008 issue of the Journal of the American Society Nephrology. view more (2008-04-03)
