Alternate Pathway That Leads To Palate Development Identified Aug 13, 2008
"For instance, we've learned that when someone has a haploid insufficiency and is missing one copy of the TGF-? gene, he or she is more vulnerable to environmental insults that can cause cleft palate, such as drugs, smoking and alcohol," Chai says. Smad4 is one of the main signaling molecules used in the TGF. (Science Daily)
Controlling Malaria Through Better Knowledge Of Genetics Of Plasmodium Populations Nov 9, 2007
With samples collected from humans, scientists can work only on the haploid phase of the parasite cycle during which only one example of each chromosome is present. Therefore they cannot measure the rate of association and organization between genes within populations. (Science Daily)

And, although those genomes were referred to as complete, they were in fact "haploid" - that is, containing a parental mosaic of the DNA letters found on just one set of the 23 chromosomes paired in every cell. However, a recent and substantially more detailed sequencing of the human genome has now shattered that comfortable belief. (India Times, India)
More detailed DNA profile produced Sep 5, 2007
You'll have incredible information about yourself," said Stephen Scherer of the Hospital for Sick Children in Toronto, who was part of the multimillion-dollar project described in today's issue of the journal PLoS Biology. "I wouldn't be surprised if Internet-based browsers pop up before long that allow you to compare your genome to others (San Francisco Chronicle)
Manipulating Nature: Scientists Query Wildlife Birth-control Method Feb 13, 2007
Professor Cooper also raises concerns that individuals that survive the vaccine may be more likely to carry infectious diseases with the potential to affect other animals. An immuno-contraceptive vaccine causes an animal's immune system to produce antibodies that act against some essential event or structure in the reproductive process. (Science Daily)
Male insecurity is sensible (for insects) Jan 26, 2007
What Werren and his colleagues found was that some of the wasps with a half-supply -- or "haploid" -- set of chromosomes, were female, not male. Only one other case of "haploid" females was ever reported. (Seacoast New Hampshire)
Young Single Men Are More Likely To Bank Sperm Before Testicular Cancer Treatment Jan 10, 2007
A quarter of men with testicular cancer banked their sperm before treatment, but only six per cent of those actually used the sperm to father a child, according to a study published in the January issue of the urology journal BJU International. Researchers from the Vanderbilt University Medical Centre in Nashville, USA, surveyed 129 males treated at the institution over a ten-year period. (Science Daily)
