St. Jude study solves mystery of mammalian ears
A 30-year scientific debate over how specialized cells in the inner ear amplify sound in mammals appears to have been settled more in favor of bouncing cell bodies rather than vibrating, hair-like cilia.   view more (2007-07-30)

Scientists take a step nearer to creating an artificial egg using a somatic cell
Scientists believe that they are an important step nearer to success in creating an artificial egg from the combination of the nucleus of a somatic cell and an oocyte which has had its DNA-carrying nucleus removed, a conference of international fertility experts heard today (Tuesday 1 July). Dr... view more (2003-06-28)

Increased environmental carbon levels - the good news!
Increasing carbon levels can be a good thing in some cases: scientists at the University of Durham propose that higher levels of inorganic carbon can have a positive influence on human health.   view more (2006-04-03)

Mutation database helps personalized treatment of lung cancer
A groundbreaking free tool to help oncologists choose the best therapies for patients with non-small-cell lung cancer has been launched this week by scientists at the 1st European Lung Cancer Conference jointly organized by the European Society for Medical Oncology (ESMO) and the International... view more (2008-04-25)

What Happens When Antidepressant Drugs Stop Working?
In this review Dr Nicoletta Sonino (Department of Statistical Sciences, University of Padava) and Dr Giovanni Fava (Department of Psychology, University of Bologna) discuss an issue that is seldom analyzed in the literature: the fact that after 2-3 months, in 10-50% of cases (depending on the... view more (2002-09-26)

Is ineffective esophageal motility associated with gastropharyngeal reflux disease?
IEM is associated with an increased acid clearance times in the distal esophagus. Gastropharyngeal reflux causes supraesophageal manifestations such as globus, chronic cough, hoarseness, asthma, chronic sinusitis, or other otorhinolaryngologic diseases.   view more (2008-11-03)

People with obsessional personalities more likely to experience heart attacks
People prone to highly obsessional thoughts and physical symptoms of anxiety are susceptible to heart attacks, finds research in Heart. A 20 year study of over 1400 men showed that those who had highly obsessional thought patterns and physical (somatic) symptoms of anxiety were significantly more... view more (2001-03-13)

Xie Lab demonstrates the role of microRNA pathway
Ting Xie, Ph.D., Associate Investigator, and Zhigang Jin, Ph.D., Postdoctoral Research Associate in the Xie Lab, have published results showing that the microRNA pathway is essential for controlling self-renewal of germline stem cells and somatic stem cells in the Drosophila ovary.   view more (2007-02-16)

Minimally invasive treatment helps infertile couples conceive
Couples struggling with infertility face uncertain odds when considering various treatment options. But a new study reveals that embolization, a minimally invasive treatment for arguably the most common cause of infertility in men, can significantly improve a couple's chances for pregnancy.   view more (2006-11-29)

US researchers sound warning note over postponing fatherhood - new findings confirm male fertility declines with age
Further evidence that men's fertility declines with age is reported today (Thursday 6 February) in Human Reproduction[1] - Europe's leading reproductive medicine journal. A study of 97 healthy non-smoking men aged from 22 to 80 has demonstrated that, as they age, men's semen quality declines. There... view more (2003-02-02)

Researchers devise new technique for creating human stem cells
Researchers have developed a new technique for creating human embryonic stem cells by fusing adult somatic cells with embryonic stem cells.   view more (2005-08-23)

Culture and depression
The expectation that East-Asian people emphasize physical symptoms of depression (e.g. headaches, poor appetite or aches/pains in the body) is widely acknowledged, yet the few available empirical studies report mixed data on this issue.   view more (2008-07-16)

Researchers Can Cross Non-Interbreeding Plants
Researchers of the All-Russian Scientific Research Institute of Plant Cultivation, Russian Academy of Agricultural Sciences (St. Petersburg) jointly with their colleagues from Germany and Finland have grown up new lines of Solanum cultivated plants via the somatic hybridization method - hybrids of... view more (2004-11-05)

All eukaryotic kinases share 1 common set of substrates

Therapeutic cloning treats Parkinson's disease in mice
Research led by investigators at Memorial Sloan-Kettering Cancer Center (MSKCC) has shown that therapeutic cloning, also known as somatic-cell nuclear transfer (SCNT), can be used to treat Parkinson's disease in mice. The study's results are published in the March 23 online edition of the journal... view more (2008-03-24)

Image of myosin-actin interaction revealed in cover story of Molecular Cell
Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the motor protein myosin V as it "walks" along other proteins, revealing new structural insights that advance the current model... view more (2005-09-30)

Scientists prove that disputed Korean stem cell line comes from an unfertilized egg and not cloning
Can a genetic signature identify the origin of a human stem cell line? Scientists report that a widely available method for comprehensive genetic analysis can help distinguish the type of human embryo that stem cells come from.   view more (2007-08-03)
