What do chocolates, flowers, jewelry, dining out and rearranging the deck chairs on the Titanic have in common? All of them will not prevent the demise of something that initially appears awesome and invulnerable. So says psychotherapist Charlette Mikulka, LCSW, author of Peace in the Heart and Home: A Down-to-Earth Guide to Creating a Better Life for You and Your Loved Ones. All she has learned has convinced her that, as time goes by, couples inevitably encounter dangerous waters. Her book is jam-packed with explanations, solutions and hope. Mikulka advises, "In order ...

ANN ARBOR, Mich.---Amid concerns about the lagging math and science performance of American children, American adults are actually scoring higher than they did 20 years ago on a widely used index of civic scientific literacy, according to a University of Michigan researcher. In 1988, just 10 percent of U.S. adults had sufficient understanding of basic scientific ideas to be able to read the Tuesday Science section of The New York Times, according to Jon Miller, a researcher at the U-M Institute for Social Research (ISR). By 2008, 28 percent of adults scored high enough ...

ALEXANDRIA, Va. – New studies on the screening and treatment of genitourinary cancers were released today in advance of the fourth annual Genitourinary Cancers Symposium, being held February 17-19, 2011, at the Orlando World Center Marriott in Orlando, Florida. The results of three studies were highlighted in a media presscast (press briefing via live webcast): Large screening study shows reduced risk of prostate cancer death for men with low initial PSAs: A large prostate cancer screening study of middle-aged and elderly men showed that an initial Prostate-Specific ...

Patients newly diagnosed with Alzheimer's disease or other dementias, and their families, need better guidance from their physicians on how to plan for the patient's progressive loss of ability to handle finances, according to a study led by a physician at the San Francisco VA Medical Center and the University of California, San Francisco. "When a patient is diagnosed with Alzheimer's disease or dementia, the chance that their physician will discuss advance planning for finances is miniscule," said lead author Eric Widera, MD, a geriatrician at SFVAMC. "And yet when family ...

Singapore - Nantes (France) – February 15, 2011 (SGT) - The Singapore Immunology Network (SIgN), an institute of the Agency of Science, Technology and Research (A*STAR), and VIVALIS (NYSE Euronext: VLS), a French biopharmaceutical company, announced today the discovery of two new fully human monoclonal antibodies which could battle Chikungunya, a disease that currently has no available vaccine or specific treatment. The international team of scientists, coordinated by Dr Lucile Warter of SIgN, has published their groundbreaking discovery in the Journal of Immunology. Chikungunya ...

In fact, according to new research from Johns Hopkins, the fusion of muscle cells is a power struggle that involves a smaller mobile antagonist that points at, pokes and finally pushes into its larger, stationary partner using a newly identified finger-like projection. In a report published Nov. 29 in the Journal of Cell Biology, the researchers described experiments using fruit fly embryos to identify an invasive projection propelled by the rapid elongation of actin filaments as the main player in the cellular power struggle. "We found that two muscle cells don't simply ...

Seniors with hearing loss are significantly more likely to develop dementia over time than those who retain their hearing, a study by Johns Hopkins and National Institute on Aging researchers suggests. The findings, the researchers say, could lead to new ways to combat dementia, a condition that affects millions of people worldwide and carries heavy societal burdens. Although the reason for the link between the two conditions is unknown, the investigators suggest that a common pathology may underlie both or that the strain of decoding sounds over the years may overwhelm ...

In an opinion piece published Feb. 10 in the journal Science, a team of scholars led by a Johns Hopkins bioethicist urges the scientific community to act collectively to stem the negative effects of the patenting and privatizing of stem cell lines, data and pioneering technologies. This means grappling with the ambiguity of several fundamental distinctions typically made in ethics, law and common practice, the experts insist. The team, led by Debra Mathews, Ph.D., M.A., of the Johns Hopkins Berman Institute of Bioethics, says failures to properly manage the widespread ...

University of Tennessee, Knoxville, researchers have found that blue-green algae may be responsible for producing an estrogen-like compound in the environment which could disrupt the normal activity of reproductive hormones and adversely affect fish, plants and human health. Previously, human activities were thought solely responsible for producing these impacts. Theodore Henry, an adjunct professor for UT Knoxville's Center for Environmental Biotechnology and faculty at the University of Plymouth, and his colleagues looked into blue-green algae, or cyanobacteria, and ...

STANFORD, Calif. — A recently discovered biomarker could help doctors diagnose a common type of knee injury, according to a new study. A team of researchers led by Gaetano Scuderi, MD, clinical assistant professor of orthopaedic surgery at Stanford University School of Medicine and an orthopaedic surgeon at Stanford Hospital & Clinics, has confirmed that a particular protein complex appears in patients with painful meniscal tears. The finding, to be published Feb. 16 in The Journal of Bone and Joint Surgery, could be used to prevent needless surgery and to save billions ...

A 22-year study of abnormally short individuals suggests that growth-stunting mutations also may stunt two of humanity's worst diseases. Published in Science Translational Medicine, part of the Science family of journals, the study raises the prospect of achieving similar protection in full-grown adults by other means, such as pharmaceuticals or controlled diets. The international study team, led by cell biologist Valter Longo of the University of Southern California and Ecuadorian endocrinologist Jaime Guevara-Aguirre, followed a remote community on the slopes of the ...

Messier 78 is a fine example of a reflection nebula. The ultraviolet radiation from the stars that illuminate it is not intense enough to ionise the gas to make it glow — its dust particles simply reflect the starlight that falls on them. Despite this, Messier 78 can easily be observed with a small telescope, being one of the brightest reflection nebulae in the sky. It lies about 1350 light-years away in the constellation of Orion (The Hunter) and can be found northeast of the easternmost star of Orion's belt. This new image of Messier 78 from the MPG/ESO 2.2-metre telescope ...

A high proportion of patients with high blood pressure are failing to take their medication properly and would benefit clinically from a course of 'adherence therapy', according to new research from the University of East Anglia (UEA). High blood pressure – or hypertension – is one of the major cardiovascular diseases worldwide. It leads to stroke and heart disease and costs more than $300 billion each year. Around a quarter of the adult population is affected – including 10 million people in the UK. Around half of patients with hypertension fail to reduce their blood ...

DETROIT – Biopsies using ultrasound fusion imaging for detecting bone and soft tissue cancers are safe, effective and just as accurate as conventional biopsy methods, according to a Henry Ford Hospital study. Researchers found that the ultrasound fusion imaging technique guides a needle biopsy with precise accuracy and ease, while making the biopsy experience more convenient for patients. Ultrasound fusion merges real-time ultrasound images with previously acquired computed tomography or magnetic resonance imaging scans, providing physicians with high resolution, life-like ...

DETROIT – While the choices of knee implants are plentiful, the success of total knee replacement surgery still is dependent on the surgeon's skill, Henry Ford Hospital researchers say. Researchers found that utilizing a series of common but nuanced surgical techniques is far more important to customizing the fit of a patient's implant than the implant's design. The findings will be displayed at the annual meeting of the American Academy of Orthopaedic Surgeons Feb. 15-18 in San Diego. "Customized knee implants will not replace the need for precise, methodical surgical ...

Almost 600 million years ago, before the rampant evolution of diverse life forms known as the Cambrian explosion, a community of seaweeds and worm-like animals lived in a quiet deep-water niche under the sea near what is now Lantian, a small village in Anhui Province of South China. Then they simply died, leaving some 3,000 nearly pristine fossils preserved between beds of black shale deposited in oxygen-free waters. Scientists from the Chinese Academy of Sciences, Virginia Tech in the U.S., and Northwest University in Xi'an, China report the discovery of the fossils ...

Pneumococcus (Streptococcus pneumoniae) accounts for as much as 11 percent of mortality in young children worldwide. While successful vaccines like Prevnar® exist, they are expensive and only work against specific pneumococcal strains, with the risk of becoming less effective as new strains emerge. Through a novel discovery approach, researchers at Children's Hospital Boston and Genocea Biosciences, Inc., in collaboration with the international nonprofit organization PATH, developed a new vaccine candidate that is potentially cheaper and able to protect against any pneumococcal ...

Who do you look at in a group photo? If you're like most adults, you'll look at yourself first — unless your boss is also in the picture. A study in PLoS ONE by researchers from the Brain and Creativity Institute at USC and Peking University examines how White Americans and Chinese people in China respond to pictures of their boss, suggesting cultural differences in our responses to authority figures. Unlike people in China, who responded fastest to pictures of their direct supervisor, White Americans responded faster to pictures of their own face than to pictures of ...

WASHINGTON— George Washington University researcher, Dr. Valerie Hu, Professor of Biochemistry and Molecular Biology, and her team at the School of Medicine and Health Sciences, have found that male and female sex hormones regulate expression of an important gene in neuronal cell culture through a mechanism that could explain not only higher levels of testosterone observed in some individuals with autism, but also why males have a higher incidence of autism than females. The gene, RORA, encodes a protein that works as a "master switch" for gene expression, and is critical ...

New fossil discoveries have provided a glimpse into the biogeographic configuration of Africa over the last seven million years. Modern-day Africa south of the Sahara is home to a unique variety of mammals, a great number of which are not found anywhere else in the world. Biogeographers have long recognized that sub-Saharan Africa constitutes one of the world's six major mammalian biogeographic divisions, termed 'realms'. However, the historical development of these continental regions of biogeographic diversity has been little explored. Description of six million-year-old ...

"Too simple" and "not so fast" suggest biological anthropologists from the George Washington University and New York University about the origins of human ancestry. In the upcoming issue of the journal Nature, the anthropologists question the claims that several prominent fossil discoveries made in the last decade are our human ancestors. Instead, the authors offer a more nuanced explanation of the fossils' place in the Tree of Life. They conclude that instead of being our ancestors the fossils more likely belong to extinct distant cousins. "Don't get me wrong, these ...

When doctors discover high concentrations of regulatory T cells in the tumors of breast cancer patients, the prognosis is often grim, though why exactly has long been unclear. Now new research at the University of California, San Diego School of Medicine suggests these regulatory T cells, whose job is to help mediate the body's immune response, produce a protein that appears to hasten and intensify the spread of breast cancer to distant organs and, in doing so, dramatically increase the risk of death. The findings are reported in the Feb. 16 advance online edition ...

It has been long known that stress plays a part not just in the graying of hair but in hair loss as well. Over the years, numerous hair-restoration remedies have emerged, ranging from hucksters' "miracle solvents" to legitimate medications such as minoxidil. But even the best of these have shown limited effectiveness. Now, a team led by researchers from UCLA and the Veterans Administration that was investigating how stress affects gastrointestinal function may have found a chemical compound that induces hair growth by blocking a stress-related hormone associated with ...

Montreal, February 16, 2011 – Recent studies conducted at the Institut de recherches cliniques de Montréal (IRCM) on a group of PCSK enzymes could have a positive impact on health, from cholesterol to osteoporosis. A team led by Dr. Nabil G. Seidah, Director of the Biochemical Neuroendocrinology research unit, has published six articles in prestigious scientific journals over the past four months, all shedding light on novel functions of certain PCSK enzymes. PCSK enzymes belong to the proprotein convertase family, responsible for the conversion of an inactive protein ...

Researchers from the Department of Neurology at NYU Langone Medical Center identified potential benefits of a new computer application that automatically detects subtle brain lesions in MRI scans in patients with epilepsy. In a study published in the February 2011 issue of PLoS ONE, the authors discuss the software's potential to assist radiologists in better identifying and locating visually undetectable, operable lesions. "Our method automatically identified abnormal areas in MRI scans in 92 percent of the patients sampled, which were previously identified by expert ...
