'Critical baby step' taken for spying life on a molecular scale

The ability to image single biological molecules in a living cell is something that has long eluded researchers; however, a novel technique, using the structure of diamond, may well be able to do this and potentially provide a tool for diagnosing, and eventually developing a treatment for, hard-to-cure diseases such as cancer. In a study published today, Thursday, 19 May, in the Institute of Physics and the German Physical Society's New Journal of Physics, researchers have developed a technique, exploiting a specific defect in the lattice structure of diamond, to externally ...

Lizard fossil provides missing link in debate over snake origins

Until a recent discovery, theories about the origins and evolutionary relationships of snakes barely had a leg to stand on. Genetic studies suggest that snakes are related to monitor lizards and iguanas, while their anatomy points to amphisbaenians ("worm lizards"), a group of burrowing lizards with snake-like bodies. The debate has been unresolved--until now. The recent discovery by researchers from the University of Toronto Mississauga and the Museum für Naturkunde Berlin, Germany of a tiny, 47 million-year-old fossil of a lizard called Cryptolacerta hassiaca provides ...

What's the Difference Between Juvederm, Restylane and Elevess?

With time, your facial skin begins to lose its structure and volume. The result is unpleasant wrinkles that can make you feel old and unattractive. There are three injectable gel forms of hyaluronic acid, a natural complex sugar found in all living cells that can help mask the effects of aging: Juvederm, Restylane and Elevess. The complex sugar in the hyaluronic acid gel is one of the major components of your skin. This gel makes wrinkle correction possible by retaining water much like a sponge. In fact, it can absorb more than 1,000 times its weight, helping to attract ...

End of life care for cancer patients differs in US and Canada

In the United States, older patients with advanced lung cancer make much less use of hospital and emergency room services at the end of life than their counterparts in Ontario but use far more chemotherapy, according to a study published May 18th online in the Journal of the National Cancer Institute. Government-financed health care covers elderly patients in both Canada and the U.S., but coverage at the end of life differs. In the U.S., Medicare covers hospice care for qualified patients. Ontario, the most populous Canadian province, has no hospice program comparable ...

Astronomer Bennett's team discovers new class of planets

University of Notre Dame astronomer David Bennett is co-author of a new paper describing the discovery of a new class of planets — dark, isolated Jupiter-mass bodies floating alone in space, far from any host star. Bennett and the team of astronomers involved in the discovery believe that the planets were most likely ejected from developing planetary systems. The study is described in a paper appearing in the May 19th issue of the journal Nature. The discovery stems from an analysis of observations of the central bulge of the Milky Way galaxy taken in 2006 and 2007 by ...

Errors in protein structure sparked evolution of biological complexity

Over four billion years of evolution, plants and animals grew far more complex than their single-celled ancestors. But a new comparison of proteins shared across species finds that complex organisms, including humans, have accumulated structural weaknesses that may have actually launched the long journey from microbe to man. The study, published in Nature, suggests that the random introduction of errors into proteins, rather than traditional natural selection, may have boosted the evolution of biological complexity. Flaws in the "packing" of proteins that make them more ...

Scared of the Dentist? Relax with Sedation Dentistry

Does the mere thought of going to the dentist make you uneasy? Do you routinely put off important dental work because of an irrational fear about the entire process? You are not alone. While dental anxiety often stems from a bad experience, sometimes just the sound of dental equipment or the prospect of a certain procedure can set patients on edge, even if they have no bad memories to draw from. Dental anxiety is more common than you might think. To help patients relax and safely receive the dental treatment(s) they need, many dentists now offer sedation dentistry (also ...

New cell therapy to prevent organ rejection

Researchers at King's College London have used cells found naturally in the body, to re-educate the immune system to prevent rejection of an organ transplant while remaining capable of fighting infections and cancer. Currently, patients must take immunosuppressant drugs to prevent a new organ from being rejected after transplantation. However, these drugs suppress the entire immune system, leaving the patient susceptible to infections and tumours. Scientists say this new approach using immune cells, called regulatory T cells (Tregs), from the body could eliminate ...

Accurate Mammograms With Breast Implants

Breast implants may obstruct some mammogram imaging, but this does not mean breast implants render mammograms ineffective as a means of screening for breast cancer. Breast augmentation surgery remained the most popular cosmetic surgery procedure in 2010, with 296,000 procedures performed last year alone, according the annual statistics report from the American Society of Plastic Surgeons. With that number continuing an upward trend over the past decade, more mammogram technicians and radiologists have experience conducting and reading the results of mammograms of women ...

Artificial tissue promotes skin growth in wounds

ITHACA, N.Y. - Victims of third-degree burns and other traumatic injuries endure pain, disfigurement, invasive surgeries and a long time waiting for skin to grow back. Improved tissue grafts designed by Cornell scientists that promote vascular growth could hasten healing, encourage healthy skin to invade the wounded area and reduce the need for surgeries. These so-called dermal templates were engineered in the lab of Abraham Stroock, associate professor of chemical and biomolecular engineering at Cornell and member of the Kavli Institute at Cornell for Nanoscale Science, ...

Hospitals misleading patients about benefits of robotic surgery, study suggests

An estimated four in 10 hospital websites in the United States publicize the use of robotic surgery, with the lion's share touting its clinical superiority despite a lack of scientific evidence that robotic surgery is any better than conventional operations, a new Johns Hopkins study finds. The promotional materials, researchers report online in the Journal for Healthcare Quality, overestimate the benefits of surgical robots, largely ignore the risks and are strongly influenced by the product's manufacturer.

Growing Numbers Of Young Patients In Nursing Homes

The common view of a nursing home is a building full of old people, in walkers and wheelchairs, white hair and bingo games. A recent story from the Associated Press notes that there is a growing population of young (less than 65 years-old) people in nursing homes and long-term care facilities. While those 30 and younger only number one percent of the nursing home population, the number of those younger than 65 have increased 22 percent in the last eight years. A report from NPR notes that ages 31-65 now make up 14 percent of nursing home populations. This is up from ...

Species extinction rates have been overreported, new study claims

The most widely used methods for calculating species extinction rates are "fundamentally flawed" and overestimate extinction rates by as much as 160 percent, life scientists report May 19 in the journal Nature. However, while the problem of species extinction caused by habitat loss is not as dire as many conservationists and scientists had believed, the global extinction crisis is real, says Stephen Hubbell, a distinguished professor of ecology and evolutionary biology at UCLA and co-author of the Nature paper.

High pregnancy weight gain can lead to long-term obesity

Gaining more than the recommended weight during pregnancy can put women at increased risk of becoming obese and developing related health problems, including high blood pressure, later in life. These are the latest findings from researchers at the Avon Longitudinal Study of Parents and Children (ALSPAC)/Children of the 90s at the University of Bristol. Weight gain during pregnancy is necessary for the growth and development of the fetus but the study, which looked at the health of 3,877 women 16 years after they gave birth, found that those who gained more than the ...

From gene to protein -- new insights of MDC researchers

How do genes control us? This fundamental question of life still remains elusive despite decades of research. Genes are blueprints for proteins, but it is the proteins that actually carry out vital functions in the body for maintaining life. Diseases such as cancer are not only characterized by altered genes, but also by disturbed protein production. But how is protein production controlled?
