Worried about your child’s exposure to
phthalates, the chemical compounds used as plasticizers in a wide variety of personal care products, children’s toys, and medical devices? Phthalate exposure can begin in the womb and has been associated with negative changes in endocrine function.
A new study in
The Journal of Pediatrics examines the possibility that in utero phthalate exposure contributes to low birth weight in infants. Low birth weight is the leading cause of death in children under 5 years of age and increases the risk of cardiovascular and metabolic disease in adulthood.
In a unique study of four previously convicted adult male pedophiles (Mage = 33.8, SD 9.7 years), utilizing structural magnetic resonance imaging (MRI) and imaging genomics (neuroimaging combined with genetic analyses), the authors propose that small variations in genotypes are responsible for paraphilic phenotypic expression (Tost, Vollmert, Brassen, Schmitt, Dressing, Braus, 2004).
An enormous plume of water spurts in giant jets from the south pole of Saturn's moon Enceladus and a report published in Nature provides evidence that this magnificent plume is fed by a salty ocean.
The Cassini spacecraft made a surprising discovery about Saturn's sixth largest moon, Enceladus, on its exploration of the giant ringed planet in 2005. Enceladus ejects water vapor, gas and tiny grains of ice into space hundreds of kilometres above the moon's surface.
In the 360 blog (sub-heading, “12 tables, 24 chairs, and plenty of chalk”), blogger Ξ (Xi) recently wrote about “Ethiopian Multiplication” (and followed it up with a series of interesting posts on different ways to multiply, here, here, here, and
Thinking of heading down to the Ms. Adrenaline Swimsuit Competition? Not surprising. Sex attracts and naked bodies flaunted for all to see, attract even more. Researchers from four universities across the US and Canada prodded into our sexual habits to answer the question of what characteristics attract us to our mates. The results were published in the journal Personality And Individual Differences, with a trend line showing those with hard bodies, a curvy waist-hip ratio and strong chin lines tend to be better in bed but perhaps more apt to cheat.
High cholesterol levels are considered to be a risk factor not only for cardiovascular disease including stroke, but also for the development of Alzheimer's disease so cholesterol lowering drugs, including statins, developed in recent years may help with both. In addition to the cholesterol reducing effect of statins Amalia Dolga, PhD, of the University of Groningen, The Netherlands, and her co-investigators have demonstrated that statins can protect nerve cells against damage which we know to occur in the brain of Alzheimer's disease patients.
The results are published in the June issue of the Journal of Alzheimer's Disease.
Rearrangements in genomes, genes and exons can result from a glitch in DNA copying that occurs when the process stalls at a critical point and then shifts to a different genetic template, duplicating and even triplicating genes or just shuffling or deleting part of the code within them, said researchers from Baylor College of Medicine in a recent report in Nature Genetics. The report further elucidated the effect of the fork stalling and template switching mechanism involved in some forms of copy number variation.
In England and Wales, the national health statistics in 2007 showed that there were 8,324 death certificates which named Clostridium difficile. This is a bacterium which causes severe diarrhea in humans and animals as the underlying cause of death, a 28% increase from 2006.
Now Janet Nale of the Department of Infection, Immunity and Inflammation is investigating the contributing factors that make Clostridium difficile so aggressive to direct treatment.
Nale said: “Bacteriophages are viruses that infect bacteria and some can completely change the behaviour of their host bacteria, or affect its ability to cause disease. In some cases, bacteriophages have been shown to convert a mild strain to a severe one.
Ken Miller vs. Jerry Coyne: Can you believe in God and evolution? Many creationists say no. But so does Jerry Coyne, as well as a fair number of other non-believing scientists active in the blogosphere. If you follow the science blogging community, you've probably tuned in to, or at least overhead snippets of, the debate between the believing Ken Miller, and the non-believer Jerry Coyne. Both are well-regarded scientists, with impressive research track records, and both are very outspoken opponents of creationism and intelligent design, as well as defenders of evolution.
Many people will write columns, fiction, games, et cetera for the joy of doing it. But that leads me to an important distinction between writing versus publishing. Writers-- good and bad-- will write for free. History tells us that. But a good editor won't, and publishing great works requires great editors.
In all the Web2.0 talk of removing barriers between creators and audience, the role of 'publisher' is often considered a dark ages legacy, fit to be abolished. But the role of editor rarely is invoked, and I think that's a mistake. Yes, the editor is the bane to writers, but they are a hidden blessing to readers.
