Chromosomes dance and pair up on the nuclear membrane
Meiosis – the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell – is a major crossroads in all organisms reproducing sexually. Yet, how the cell preci...

Read moreLandmark study sheds new light on human chromosomal birth defects
That discovery is groundbreaking, but so, too, is what principal investigator Hong-Guo Yu calls the "genetics trick" performed by his research team that made the discovery possible. The stud...
Life Sciences | Read moreNew technique could eliminate inherited mitochondrial disease
Researchers funded by the National Institutes of Health have developed an experimental technique with the potential to prevent a class of hereditary disorders passed on from mother to child. The techn...
Health and Medicine | Read moreStudies shed light on preserving fertility among cancer patients
These successes, however, have created a challenge for young cancer patients since chemotherapy and radiation treatments that often save lives threaten fertility. Techniques available to safeg...

A few years ago, scientists at the University of Idaho discovered birth control pills not only control the human population, but also can devastate rainbow trout populations. Now they may know why....
Ecology, The Environment and Conservation | Read moreGene screen to identify causes of autism
By screening for genetic defects associated with various kinds of cognitive impairment, the approach described in the open access journal BMC Medical Genomics will help clinicians identify the underly...
Life Sciences | Read moreNew blood test for Down syndrome
Researchers have long known that a pregnant woman's blood contains small amounts of DNA from the fetus. Howard Hughes Medical Institute researcher Stephen R. Quake and colleagues at Stanford Univ...

Details of how the process works someday may provide new ways to treat cancer.The new study of fruit flies is the first to show in animals that losing just one telomere – the end of a chromoso...
Life Sciences | Read moreNormal-looking sperm may have serious damage; scientists urge more care in selection
Although the sperm chosen for the procedure may appear quite normal, researchers in the US have found that many of them in fact have DNA damage, which can decrease the chances of pregnancy.Mr....
Health and Medicine | Read moreSt. Jude discovery offers new avenues to understanding an aggressive form of leukemia
Researchers at St. Jude Childrenˇ¦s Research Hospital have discovered evidence that a series of genetic mutations work together to initiate most cases of an aggressive and often-fatal form of acute ly...
Life Sciences | Read moreUCLA researchers examine human embryonic stem cell genome
The technique used to study the genome, which contains all the genes on 46 chromosomes, is called array CGH. The use of higher resolution techniques, such as array CGH and, soon, whole genome sequenci...
Life Sciences | Read moreNew cataract gene discovered
Researchers at ETH Zurich and the University Zurich have identified the chromosomal location and exact molecular defect in the coding region of the gene responsible for a childhood cataract. Until now...
Life Sciences | Read moreBubR1: new clues for Down Syndrome?
The research about to be published in the journal Current Biology shows that BubR1- a gene recently shown to affect cell division – maintains the cohesion of paired chromosomes (until their time to di...
