Small molecule derived from Rb2/p130 could act as cancer therapeutic
A small molecule derived from the spacer domain of the tumor-suppressor gene Rb2/p130 has demonstrated the ability to inhibit tumor growth in vivo and could be developed into an anti-cancer therapeutic, according to researchers at Temple University's Sbarro Institute for Cancer Research and Molecular Medicine. view more (2007-03-21)
HSP90: New point of view on melanoma of the eye, at the MUHC
Ocular melanoma is rarely detected before it has grown large enough to impair vision or to metastasize. This makes it a particularly challenging disease to fight, especially since chemotherapy is not very effective. view more (2008-02-20)
Agricultural soil erosion not contributing to global warming, study shows
Agricultural soil erosion is not a source of carbon dioxide to the atmosphere, according to research published online in Science. view more (2007-10-26)
Scientists Clarify a Mechanism of Epigenetic Inheritance
Although letters representing the three billion pairs of molecules that form the "rungs" of the helical DNA "ladder" are routinely called the human "genetic code," the DNA they comprise transmits traits across generations in a variety of ways, not all of which depend on the sequence of letters in the code. view more (2008-04-23)
MIT, Harvard offer solution to Mars enigma
Planetary scientists have puzzled for years over an apparent contradiction on Mars. Abundant evidence points to an early warm, wet climate on the red planet, but there's no sign of the widespread carbonate rocks, such as limestone, that should have formed in such a climate. view more (2007-12-26)
Stem cell identity in culture may strongly depend on the cellular microenvironment
Identification, isolation and large scale culture of stem cells for potential medical applications is a major challenge in cell biology. view more (2007-04-25)
Researchers solve mystery of how nuclear pores duplicate before cell division
Researchers have long wondered how nuclear pores - the all-important channels that control the flow of information in and out of a cell's nucleus - double in number to prepare for the split to come when a cell divides. view more (2006-04-21)
Emory researchers identify signaling protein for multiple myeloma
Researchers at Emory University's Winship Cancer Institute are the first to discover a mechanism that plays a critical role in the multiple myeloma cell cycle and survival. view more (2007-09-11)
Shift toward services industries won't end global warming
The shift toward a service-based economy won't automatically reduce the amount of greenhouse gases (GHS) in the air, a University of Minnesota researcher has found. His research contradicts assumptions about global warming often preferred by some economists and national policy experts. view more (2006-11-02)
First study of children born after in vitro maturation indicates the technique is safe
Children born after female eggs were matured in the laboratory are healthy, according to the first survey of babies born using this technique. Since 1997 doctors at the Fertility Clinic in Herlev, Denmark, have been helping women to have babies using a technique called in vitro maturation. This involves taking immature oocytes (eggs) from the... view more... (2003-06-27)
Protein key to control, growth of blood cells
New research sheds light on the biological events by which stem cells in the bone marrow develop into the broad variety of cells that circulate in the blood. The findings may help improve the success of bone marrow transplants and may lead to better treatments for life-threatening blood diseases. view more (2008-08-14)
Greenhouse gas effect consistent over 420 million years
New calculations show that sensitivity of Earth's climate to changes in the greenhouse gas carbon dioxide (CO2) has been consistent for the last 420 million years, according to an article in Nature by geologists at Yale and Wesleyan Universities. view more (2007-03-29)
Stem cell regeneration repairs congenital heart defect
Mayo Clinic investigators have demonstrated that stem cells can be used to regenerate heart tissue to treat dilated cardiomyopathy, a congenital defect. view more (2008-09-12)
Tearing down the fungal cell wall
Scientists at the Virginia Bioinformatics Institute and Duke University Medical Center have pinpointed a fungal gene that appears to play an important role in the development and virulence of Alternaria brassicicola. view more (2006-12-05)
Cholera pathogen reveals how bacteria generate energy to live
Researchers at Rensselaer Polytechnic Institute have discovered new details about how bacteria generate energy to live. In two recently published papers, the scientists add key specifics to the molecular mechanism behind the pathogen that causes cholera. view more (2007-01-30)
Human activities in arid urban environments can affect rainfall and water cycle
In the past half-century, cities have begun to expand in some of the Earth's most arid areas. While scientists have known for some time that the so-called "heat-island" effect of large cities such as Atlanta and Houston can affect their weather, they knew less about this effect and other processes in arid cities, such as Phoenix, which... view more...

MU Scientist Uses Tracer to Predict Ancient Ocean Circulation
Even though the Cretaceous Period ended more than 65 million years ago, clues remain about how the ocean water circulated at that time. view more (2008-10-21)
The downside of microtubule stability
Stalled microtubules might be responsible for some cases of the neurological disorder Charcot-Marie-Tooth (CMT) disease. view more (2009-06-15)
Immune deficiency linked to a type of eye cancer
The incidence of squamous cell eye cancer is greater among kidney transplant patients and people with human immunodeficiency virus (HIV) than the general public, which suggests the disease is associated with immune deficiency. view more (2007-08-15)
Spanish fertility experts bring hope of avoiding serious complication of assisted reproduction
Research by Spanish fertility experts is bringing new hope to women of avoiding a serious complication of assisted reproduction - ovarian hyperstimulation syndrome (OHSS)[1]. In its severest form, which requires urgent medical treatment, the syndrome affects around 200 women a year in Spain and as many as 2,000 a year in Europe. OHSS occurs when a... view more...
