| • | Agriculture: Gray Mold's Killer Gene Discovered | ||
| Gray mold is a gardener?s nightmare. The fungus, also known by its scientific name Botrytis cinerea, is a scourge to more than 200 agricultural and ornamental plant species, including staples such as tomatoes, strawberries, snap and lima beans, cabbage, lettuce and endive, peas, peppers, and potatoes. Chemists have now identified the genetic sequence behind gray mold's killer arsenal. The scientists report that deletion of a single, mastermind gene from gray mold's DNA shuts down its ability to produce toxins that kill cells in more than 200 species of garden and ornamental plants. | |||

|
Large studies on semen quality of the general healthy population from China are rare. A cross-sectional study was performed to evaluate the semen quality of 1346 healthy men residing in Chongqing area of southwest China in 2007. The semen parameters were measured and compared with the World Health Organization (WHO) criteria. A linear regression model was used to examine the determinants of semen quality. The medians were 2.3 ml for semen volume, 77.8 x 106 per ml for semen concentration, 167.7 x 106 for total sperm count, 33% for sperm rapid progressive motility, 52.6% for sperm progressive motility and 70.9% for total motility. According to WHO criteria, 61.1% of healthy males had at least one semen parameter below normal threshold values. Season and abstinence duration were found to be significantly associated with semen quality (P < 0.001). Age, smoking, alcohol use and BMI had little or no effect on semen parameters. A high proportion of healthy males in Chongqing area of southwest China had abnormal semen parameters values according to WHO criteria. The semen parameters in the study population were markedly different from those reported for the other Chinese, USA and European populations. The differences remain unexplained and may be due to demographic characteristics, lifestyle, environmental factors or genetic variation. |

| Ancient Greece is on the naked scientists' menu this week as we travel back in time to 1200 BC to discover how modern science and a 3000 year old poem have solved an ancient riddle. A team of classicists, geologists and archaeologists claim to have found the island of Ithaca, home of the legendary Greek hero Odysseus. Digging further into the past we also hear how geophysics can help archaeologists to see what lies buried underground but without having to lift a trowel. We also learn how dormant brain stem cells can be brought back to life, why it's not just size that is important when it comes to brains, and the mind-controlling parasite that turns its host first into an egg-incubator and then into a bodyguard. Plus, in Kitchen Science, savouring the Greek flavour, Ben and Dave recreate the science of the original Naked Scientist, Archimedes, and find out whether a heap of gold coins are the real thing... | |||

| • | Chemical From Medicinal Plants May Be Used To Fight HIV | ||
| Immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division. As a result, its disease fighting ability is compromised. A new study finds that a chemical from the Astragalus root, frequently used used in Chinese herbal therapy, can prevent or slow this progressive telomere shortening, which could make it a key weapon in the fight against HIV. | |||

| • | Antimalarial Activities of Some Selected Traditional Herbs from South Eastern Nigeria Against Plasmodium Species | ||
| A study of three plants traditionally used in the treatment of malaria in the Southeastern part of Nigeria was investigated to determine their efficacies as antimalarial compounds. The three herbs were collected through a traditional herbalist who uses them in his practice. Ethanolic extracts from the roots of Enyim ocha (Salacia nitida), Ovoro ilu (Nauclea latifolia) and stem bark of Erumeru (Enantia chlorantha Oliv.) were assessed for antimalarial activity against chloroquine sensitive Plasmodium berghei in mice using the 4 day suppressive test procedure. The extracts had intrinsic antimalarial properties that were dose dependent. The comparison analysis indicated that 250 mg kg-1 body weight of the root of S. nitida produced 71.15% suppression of parasitaemia and the 500 mg kg-1 body weight of the stem bark of E. chlorantha, roots of S. nitida, N. latifolia and the three herbs combined, produced 75.23, 73.28, 71.15 and 77.46%, respectively, compared with chloroquine with 71.15% suppression. The results were significant at p< 0.05 when compared to a placebo and support the traditional use of these plants for the treatment of malaria. | |||

| • | 7.342 Reading the Blueprint of Life: Transcription, Stem Cells and Differentiation, Fall 2006 (MIT) | ||
| Seminar covering topics of current interest in biology. Includes reading and analysis of research papers and student presentations. Contact Biology Education Office for topics. Description from course home page: In this course, we will address how transcriptional regulators both prohibit and drive differentiation during the course of development. How does a stem cell know when to remain a stem cell and when to become a specific cell type? Are there global differences in the way the genome is read in multipotent and terminally differentiated cells? We will explore how stem cell pluripotency is preserved, how master regulators of cell-fate decisions execute developmental programs, and how chromatin regulators control undifferentiated versus differentiated states. Additionally, we will discuss how aberrant regulation of transcriptional regulators produces disorders such as developmental defects and cancer. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching. | |||

| • | Estimating Antiviral Effectiveness Against Pandemic Influenza Using Household Data | ||
| Antiviral drugs play a central role in current plans for managing an influenza pandemic. However, their ability to reduce symptoms and infectivity in cases, and to reduce susceptibility of individuals given antivirals prophylactically must be confirmed for the pandemic virus strain. We present a technique for estimating antiviral effectiveness from data that can gathered easily from infected households during the early stages of an influenza pandemic. | |||

| • | A fluorescein-based fluorogenic and chromogenic chemodosimeter for the sensitive detection of sulfide anion in aqueous solution. | ||
| Authors: Yang XF, Wang L, Xu H, Zhao M A highly sensitive chromo- and fluorogenic chemodosimeter for sulfide anion was developed based on its nucleophilicity. 2,4-Dinitrobenzenesulfonyl-fluorescein (I) is a weakly fluorescent compound. Upon mixing with sulfide anion in aqueous acetone solution, the 2,4-dinitrobenzenesulfonyl group of I was efficiently removed and highly fluorescent fluorescein was released, hence leading to the dramatic increases in both fluorescence and absorbance of the reaction solution. The fluorescence increment is linear with sulfide anion concentration in the range 50-1000nmolL(-1) with a detection limit of 4.3nmolL(-1) (3sigma). The proposed chemodosimeter showed excellent selectivity toward sulfide anion and was successfully applied to the determination of sul... | |||

| • | Drug offers new alzheimer's hope | ||
| A drug commonly used to control epilepsy could soon have a new role as a treatment for Alzheimer's disease. Researchers have found that sodium valproate, marketed in Britain as Epilim, stimulates the body's natural defences against the disease.They found that the drug boosted production of an enzyme which prevents the build-up of proteins in brain cells. These accumulations, or plaques, of protein have been shown by researchers to trigger the onset of Alzheimer's.Crucially, valproate has already been passed by Britain's stringent drug safety watchdog as an epilepsy drug, and could be brought into widespread use fairly rapidly if research results are confirmed, scientists told The Observer.'We are still in the early days of our work, but are very excited about the potential of valproate,' s... | |||

| • | Social status shapes racial identity [Not Exactly Rocket Science] | ||
Penner and Saperstein used data from a study called the National Longitudinal Survey of Youth, which began in 1979 by interviewing a group of about 12,000 Americans aged 14 to 22. The sample were followed once a year until 1993 and every two years thereafter. Every time, the interviewers classified each person as "White", "Black" or "Other" and in both 1979 and 2002, the people themselves were asked to describe their "origin or descent" or which "race or races they considered themselves to be". The results were surprising, especially for a country like the US, which apparently has very rigid racial boundaries. Over the 19 years of the survey, the race of about one in five people had changed at least once in the eyes of their interviewers. Read the rest of this post... | Read the comments on this post... |
