The minute the words are said, the regret sets in.
Communication scientists from Case Western Reserve University and Kent State University have studied how and why people choose certain ways to repair the damage done once hurtful words are spoken.
According to Jane R. Meyer from Kent State and Kyra Rothenberg from Case, most people offered an apology, spurred by guilt to mend any offense their remarks might cause in an intimate relationship. Following the offer of an apo
Saint Louis University neurologist to present findings, now available on-line
A multi-national research team that includes a Saint Louis University neurologist has discovered a gene mutation that causes a rare form of Charcot-Marie-Tooth disease, an inherited progressive nerve disorder. The findings are published in an advance online issue of Nature Genetics.
Researchers have identified some 50 people from three families who live in St. Louis, Wisconsin, Belgium and Bulg
The slopes of Frascati overlooking Rome boast rich, volcanic soils: wine has been produced there since time immemorial. However the latest vine crop should go down in history as the single best documented harvest ever.
Part of Frascati’s Controlled Origin Denomination – ’Denominazione d’Origine Controllata’ or DOC in Italian, a wine’s legally demarcated home region – was surveyed in ultra-sharp detail using an airborne radar sensor both before then after la
Confirming what many have long suspected, scientists have found that male monkeys of two different species get heavier when their mates are pregnant.
The roughly 10 percent gain in male girth occurs in common marmosets and cotton-top tamarins, both squirrel-sized primates known for their monogamous lifestyles and devotion to good parenting.
Since marmoset and tamarin dads are heavily involved in infant care, they may be stocking up on pounds during pregnancy in prepar
A protein associated with the growth of head and neck tumors may be a tumor suppressor that could prevent the spread of cancer when it is expressed above normal levels, according to a study published in the Feb. 1 issue of the Journal of the National Cancer Institute (JNCI).
The study, led by University of Pittsburgh School of Medicine professor of otolaryngology and pharmacology, Jennifer Grandis, M.D., is the first to show that the expression of a protein called STAT1 may play a
A simple diagnostic imaging procedure can help identify patients with lower back pain who would benefit from spinal injections and spare those who would not, according to a study appearing in the February issue of Radiology.
Single photon emission computed tomography (SPECT) shows abnormal activity of cells in the spine, which can help doctors identify problems that may be causing a patient’s symptoms.
According to the National Institute of Neurological Disorders an
Traditional polygraph tests to determine whether someone is lying may take a back seat to functional magnetic resonance imaging (fMRI), according to a study appearing in the February issue of Radiology. Researchers from Temple University Hospital in Philadelphia used fMRI to show how specific areas of the brain light up when a person tells a lie.
“We have detected areas of the brain activated by deception and truth-telling by using a method that is verifiable against the current gold s
Transplanting patients with blood stem cells that originate from their own bone marrow can induce the remission of life-threatening, treatment-resistant lupus, according to a study that took place at Northwestern Memorial Hospital in Chicago. Researchers found that 50 percent of the 50 patients in the study had disease-free survival at five years with an overall five-year survival rate of 84 percent. The study is published in the February 1 issue of the Journal of the American Medical Association.
A blood safety program in South Africa that included closing donor clinics in areas of high HIV prevalence is associated with a decrease in the prevalence of HIV in donated blood, according to study in the February 1 issue of JAMA.
South Africa is in the midst of an escalating human immunodeficiency virus (HIV)–AIDS pandemic, with an estimated 5.3 million people and 11.4 percent of the overall population infected, according to background information in the article. The South Afr
Two studies in the February 1 issue of the Journal of the National Cancer Institute examine whether hospital volume, surgeon experience, or surgeon specialty affect the treatment received and the risk of death following treatment among women with ovarian cancer.
Past studies have suggested that patients treated at hospitals with higher case loads or by more experienced surgeons have higher survival rates after surgery for certain types of cancer, including colorectal cancer an
Two independent research papers in the February 1 issue of G&D reveal that the Drosophila UNR protein is a novel regulator of X-chromosome dosage compensation in flies. Dosage compensation is the equalization of X-linked gene expression between males (which have one X chromosome in flies) and females (which have two X chromosomes in flies). Fruit flies accomplish this by increasing transcription of the single male X chromosome two-fold. Transcriptional upregulation of the Dros. male X chromosome is
A team of Russian scientists, led by Dr. Vladimir Gvozdev (Russian Academy of Sciences) reports on a novel link between RNAi and telomere maintenance in the Drosophila germline. Unlike most eukaryotes, which use the enzyme telomerase to lengthen their chromosome ends, Drosophila telomeres are maintained by specialized telomeric retrotransposons (Het-A, TART and TAHRE) that are attached, or transposed, onto chromosome ends.
Dr. Gvozdev and colleagues have discovered that two known compon
Researchers at Yale and the University of Washington report that great earthquakes, like the 2004 Sumatra earthquake, may be caused by the build up of sediment on top of subduction zones, suggesting a new way to forecast these most severe earthquakes.
Subduction zones are the boundaries where two tectonic plates collide — one plate pushes over and one pushes under the other. The most severe earthquakes in recent history — in Indonesia in 2004, Alaska in 1964, Chile in 1960 an
A “starry sky” map linking the myriad interactions between the influenza virus and its human host will help guide researchers in creating new anti-viral drugs, say researchers at UT Southwestern Medical Center.
The on-line map, part of a project called Reactome, is intended to teach scientists about parts of the influenza lifecycle they might not be familiar with, and to help researchers look at specific reactions and figure out ways to block them.
“Understanding how influenza re
Cells may vary in numbers per embryo, be uneven-sized or partially fragmented. Dr Lieberman et al. at the Department of Obstetrics, Gynaecology and Reproductive Biology at the Brigham and Women’s Hospital, Harvard Medical School in Boston, USA have measured the quality of human embryos by counting and assessing the properties of their individual cells. In their paper Rate of cell division and weight of neonates following in-vitro fertilization, they compared the weights of 447 singleton births agai
University of Minnesota associate professor of chemical engineering Renata Wentzcovitch and her team of researchers have confirmed the properties of a mineral (post-perovskite) that may form near the Earth’s core in a layer called the D’’ region. The work offers new insight for interpreting properties of this region. The D’’ (Dee double prime) layer surrounds Earth’s core and is between 0 and 186 miles thick. It is at the interface between two chemically distinct regions, the rocky mantle and t
