As Good As Chocolate And Better Than Ice-cream: Study Asks Aussie Tots
A University of Western Sydney researcher has carried out Australia's first study of mums and bubs who breastfeed beyond infancy - looking at why these women are bucking the trend against premature weaning, and asking the toddlers themselves how they feel about breastfeeding. Precise Role Of Seminal Proteins In Sustaining Post-mating Responses I
Successful reproduction is critical to pass genes to the next generation. In sexually reproducing organisms, sperm enter the female with seminal proteins that are vital for fertility. Scientists have now knocked down the levels of 25 seminal proteins individually in male fruit flies, testing the males'abilities to modulate egg production, sperm storage and release, and the females'post-mating behavior and physiology. Adding Folic Acid To Flour Significantly Reduces Congenital Malformati
A new study shows that the addition of folic acid to flours has led to a 46 percent drop in the incidence of congenital neural tube deformation (mainly anencephaly and spina bifida) in Canada. Such deformities either result in the child's death or in major health problems, including physical and learning disabilities. Bleeding, Not Inflammation, Is Major Cause Of Early Lung Infection Dea
Researchers believe they have discovered why a bacterial lung infection is so lethal in the early stages, and it's not what medical authorities had thought. The study reveals for the first time that a toxin released by bacteria causes severe bleeding in the lungs by patients with pneumococcal pneumonia. It is the bleeding, the authors argue, not inflammation as once thought, which makes the infections deadly. The same study also reveals why antibiotics often fail to help prevent early death. Despite vaccine, one million children still die of pneumococcal infections. Peacetime Grenades Harm Environment
Elisabeth Hochschorner and colleagues from the Royal Institute of Technology in Stockholm showed that during peacetime, the mining of metals used in grenade construction and the energy costs needed to produce them cause significant environmental impact. The residues emitted during practice detonations also top the list of harmful effects. How to Write a Thank-You Note
Light-hearted guidelines to help you write thank-you notes. Suggestions include greeting the giver, expressing your gratitude (with tips such as "use the present perfect tense,"and "never directly mention money"), discussing uses, mentioning the past and alluding to the future, and signing off. From the Morning News, an online magazine. Novel Mechanism Of Protein Processing Found
Colinearity of DNA and protein sequences is thought to be a fundamental feature of the universal genetic code. However, a paper published in Science by a team from the Brussels Branch of the global Ludwig Institute for Cancer Research (LICR) and the Seattle-based Fred Hutchinson Cancer Research Center (FHCRC), shows that a protein can be rearranged so that it is no longer colinear with its encoding DNA. PSA Remains Best Indicator Of Prostate Cancer Progression
Despite recent claims by some urologists that measuring the blood protein prostate-specific antigen (PSA) may not be effective in predicting risk of prostate cancer, a Johns Hopkins study of more than 2,000 men confirms that PSA remains the best measure of the likelihood of cancer recurrence after surgery. POxy: Oxyrhynchus Online
Background information about the Oxyrhynchus papyri, which were excavated from the site of Oxyrhynchus, a regional capital in Hellenistic and Roman Egypt. Features illustrated essays about the city and the documents found there (including letters, tax returns, and government documents). Also includes a glossary, a searchable database and updates on the imaging of the papyri located at the Oxford University libraries, and locations of the rest of the papyri. Huygens Sets Off With Correct Spin And Speed
On Christmas Day 2004, the Cassini spacecraft flawlessly released ESA's Huygens probe, passing another challenging milestone for Cassini-Huygens mission. But, with no telemetry data from Huygens, how do we know the separation went well?
