The progression from the Neolithic solid stone wheel with a single hole for an axle to the sleek wheels of today's racing bikes is the result of human ingenuity but it also represents how animals, including humans, have come to move more efficiently and quicker over millions of years on Earth, according to a Duke University engineer.
A new analysis has found that two million cancer survivors did not get needed medical services in the previous year because of concerns about cost. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the study raises the concern that the long-term health and well-being of cancer survivors could suffer because patients have financial worries about their care.
WINSTON-SALEM, N.C. – Monday, June 14, 2010 – A new study led by a Wake Forest University Baptist Medical Center researcher shows that millions of cancer survivors are forgoing needed medical care because of concerns about cost.
Published early online today in CANCER, a peer-reviewed journal of the American Cancer Society, the study raises the concern that the long-term health and well-being of cancer survivors could suffer because patients have financial worries about their care.
COLLEGE STATION, June 11, 2010 – Researchers at Texas A&M University College of Veterinary Medicine & Biomedical Sciences have achieved another cloning first with the successful delivery of a foal using oocytes from a live mare, the first such clone in the world. The delivery of the foal highlights Texas A&M's long tradition of leading science in equine reproduction, and has been a great experience for the owner of the new foal.
NASA's Aqua satellite flew over the Gulf of Mexico on Thursday, June 10 at 19:05 UTC (3:05 p.m. EDT) and the satellite's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured an image of the thickest part of the oil slick.
When applied to HIV care, the community-based model of directly observed therapy (DOT) has no effect on virologic outcomes, but significantly improves patient survival. This is according to researchers at the Johns Hopkins Bloomberg School of Public Health, in collaboration with colleagues at University of Cape Town, South Africa, who conducted the first randomized controlled trial of patient-nominated treatment-supporters providing partial DOT in resource-limited settings.
The chaos caused by the Eyjafjallajokull volcanic eruption in Iceland April 2010 and the dispersal of its ash cloud across European airspace was a reminder of the tremendous forces of nature that exist below the ground. Not all subterranean heat sources have such sinister power but across Europe there are plentiful sources of geothermal energy: heat stored in the ground which can be tapped to provide a renewable and inexhaustible energy supply.
An inexpensive, but unlicensed drug to help prevent severe sight loss in older people has been shown to be safe and effective, finds a study published on bmj.com today.
Bevacizumab (Avastin) is licensed as a treatment for bowel cancer, but it is widely used "off label" as a considerably cheaper alternative to the approved drug ranibizumab (Lucentis) to prevent wet age related macular degeneration (AMD) and several large trials comparing the two drugs are now underway.
Family carers need to be supported throughout the whole illness of their loved ones as they witness and share much of the experience of the dying person, according to research published on bmj.com today.
It has already been established that individuals dying from cancer experience distress particularly at four key time points – at diagnosis, at home after initial treatment, at recurrence, and during the terminal stage, says the study.
It's no secret that sharks have a keen sense of smell and a remarkable ability to follow their noses through the ocean, right to their next meal. Now, researchers reporting online on June 10th in Current Biology, a Cell Press publication, have figured out how the sharks manage to keep themselves on course.
It turns out that sharks can detect small delays, no more than half a second long, in the time that odors reach one nostril versus the other, the researchers report. When the animals experience such a lag, they will turn toward whichever side picked up the scent first.
The differences in mothers' and fathers' interactions with their children, particularly in play situations, may influence toddlers' associations of specific behaviors with male and female genders. According to Eric Lindsey from Penn State Berks in the US, and his colleagues, context, gender of the parent and gender of the child combine in a complex pattern to shape parent-child interaction. Their findings1 are published online in Springer's journal Sex Roles.
The huge tonnages of waste steel from decommissioned offshore oil and gas structures represents a serious problem for operators looking to recoup losses and avoid environmental harm. A way to calculate the weight of the problem has been developed by US researchers and described in the International Journal of Oil, Gas and Coal Technology.
