World's largest flower evolved from family of much tinier blooms
The plant with the world's largest flower - typically a full meter across, with a bud the size of a basketball - evolved from a family of plants whose blossoms are nearly all tiny, botanists write this week in the journal Science.   view more (2007-01-12)

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... 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... view more (2001-07-18)

Tamed 11,400 years ago, figs were likely first domesticated crop
Archaeobotanists have found evidence that the dawn of agriculture may have come with the domestication of fig trees in the Near East some 11,400 years ago, roughly a thousand years before such staples as wheat, barley, and legumes were domesticated in the region.   view more (2006-06-02)

Storing carbon to combat global warming may cause other environmental problems, study suggests
Growing tree plantations to remove carbon dioxide from the atmosphere to mitigate global warming - so called "carbon sequestration" - could trigger environmental changes that outweigh some of the benefits, a multi-institutional team led by Duke University suggested in a new report.   view more (2005-12-23)

Researchers offer clues to how leaf patterns are formed
Pick up a leaf and it is hard not to notice the pattern made by the veins. For years, biologists, mathematicians and even poets and philosophers have tried to decipher the rules and regulations behind those varied designs and now new research published in part at the University of Alberta offers a... view more (2006-06-16)

'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)

Creative economy grows despite large population growth of creative people
New economic data from the University of Maine give hope to cities across the country trying to gain a foothold in the creative economy   view more (2006-07-05)

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... 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)

Ants, not evil spirits, create devil's gardens in the Amazon rainforest, study finds
For the first time, scientists have identified an ant species that produces its own natural herbicide to poison unwanted plants.   view more (2005-09-22)

UBC researchers reveal dwarf aquatic plants' hidden ancestry
A team of UBC researchers has re-classified an ancient line of aquatic plants previously thought to be related to grasses and rushes. The discovery clarifies what may be one of the biggest misunderstandings in botanical history.   view more (2007-03-15)

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... view more (2008-04-03)

New insights into how the oncogenic protein c-Myc regulates cell growth
New findings by Swedish and German scientists on the regulation of cellular growth are published in the March issue of Nature Cell Biology.   view more (2005-02-20)

Stanford researchers say living corals thousands of years old hold clues to past climate changes
Using radiocarbon dating and samples of deep-sea corals snipped from the floor of the Pacific Ocean by a submersible, researchers from Stanford and Lawrence Livermore National Laboratory have discovered that deep-sea corals growing off Hawaii are much older than previously thought-some as old as... view more (2008-02-15)

Joslin-led study uncovers role of appetite hormone MCH in insulin production
A new Joslin Diabetes Center-led study has shown conclusively that a neuropeptide, melanin concentrating hormone (MCH), found in the brain and known for its role in increasing appetite in people, plays a role in the growth of insulin-producing beta cells and the secretion of insulin.   view more (2007-01-29)

Spring into autumn to measure climate change
Volunteers have been so enthusiastic this year in recording the timing of natural events in springtime that an additional scheme is being run this autumn. Preliminary results from the huge volume of data gathered early in 1999 show that once again spring is arriving earlier in the UK. The dates... view more (1999-08-31)

Growth factor stimulates rapid extension of key motor neurons in brain
A growth factor known to be important for the survival of many types of cells stimulates rapid extension of corticospinal motor neurons - critical brain cells that connect the cerebral cortex with the spinal cord and that die in motor neuron diseases like amyotrophic lateral sclerosis (ALS or Lou... view more (2006-11-06)

New study suggests link between environmental toxins and early onset puberty in girls
Although scientists have speculated over the negative effects of environmental toxins for years, new data suggest that certain environmental toxins may disrupt the normal growth and hormonal development of girls.   view more (2008-02-07)

Omega-6 fats cause prostate tumors to grow twice as fast
Omega-6 fatty acids-such as those found in corn oil-caused human prostate tumors in cell culture to grow twice as quickly as tumors to which omega-6 fats had not been added, according to a study conducted at the San Francisco VA Medical Center.   view more (2006-02-01)

RECURRENT MISCARRIAGE AND FETAL GROWTH RETARDATION ASSOCIATED WITH COELIAC DISEASE (p 399)
Coeliac disease - a condition where wheat gluten causes dietary malabsorption to genetically-susceptible individuals - may be closely linked to recurrent spontaneous abortion or intrauterine growth retardation, according to a research letter published in this week's issue of THE LANCET. 15% of... view more (2000-07-26)

OHSU Cancer Institute researchers find connection between protein, prognosis in breast cancer
Oregon Health & Science University Cancer Institute researchers have found that a tumor protein present in an aggressive form of breast cancer is related to a poor prognosis.   view more (2008-04-14)
