Focusing on Cancer Stem Cells Many solid tumors appear to have a small population of stem cells that are partially resistant to chemotherapy and can perpetuate themselves indefinitely. These cancer stem cells thus far have been isolated from breast and brain tumors as well as blood. The exact origin of these cancer ste... |

Garden Guide '10: The Right Tools The Easy Bloom Plant Sensor shows which vegetables, fruits, herbs, flowers, trees, shrubs or houseplants will grow where, indoors or out. There are so |
many different types of gardening tools available. How do you know which ones you'll really need? For starters, you'll need something to dig with—shovel or a spade. A shovel is |
typically a scoop for mixing or moving material from one place to another. A spade is designed for digging. The blade is straighter than a shovel's and is made to |
be pushed into the soil. Long-handle tools usually offer better leverage and reach and allow working from a standing position. The handle may be either straight or have a D-shaped |
grip. With some long-handle pruners, extensions may be available. Short-handle tools are lighter, usually less expensive and more compact to store. They let you work in confined spaces or while |
kneeling. Common short-handled tools include hand pruners and clippers, hoes, garden trowels and cultivators. Using short-handle tools means spending time low to the ground. A good, firm foam pad or |
strap-on kneepads can help prevent aches and pains. Choices range from simple pads to foldable seats. Basic and not-so-basic tools - Garden knives. Useful for cutting twine and plant ties |
and opening bags and plant root balls, the safer ones have non-collapsible fixed blades. - Garden rakes. A heavy rake with short, stiff tines supported by a flat or bow-shaped |
metal frame is useful for raking heavy materials, removing rocks and other debris and smoothing the soil for planting. - Leaf rakes. A light rake with long, thin, flexible tines |
designed to gather leaves or other light materials. - Hand pruners and shears. Used for removing flowers, lightweight foliage and small branches. - Hoes. For weeding and scraping the soil's |
surface, hoes include the traditional flat scraping or chopping types and the loop, scuffle and stirrup styles. - Long-handled pruners and loppers. These long-handled versions of hand pruners provide greater |
reach and leverage, allowing for larger items to be cut. - Mattocks. A heavy, flat-bladed tool designed to dig or grub in the soil on one end, with a sharp |
point to break up heavy or rocky soils on the other. - Spading forks. Used to open up the ground, dig bulbs, incorporate soil amendments and turn compost, they have |
heavy, flat tines and often a D-shaped handle. - Tillers. A power tool that breaks up large areas of compacted soil and incorporates soil amendments. - Cultivators. A tool with |
heavy curved or bent tines or sometimes multiple spinning blades designed to open up and aerate the soil. Styles with tines are also used to mix materials and effectively loosen |
weed roots. - The Weed Wrench, a manually-operated, all-steel tool designed to remove woody weeds by uprooting them. - The Easy Bloom Plant Sensor shows which vegetables, fruits, herbs, flowers, |
trees, shrubs or houseplants will grow where, indoors or out. Storing your tools Avoid clutter and damage by keeping your tools organized and dry. There's a tremendous selection in stores |
and online of storage racks, systems, tool organizers, outdoor closets and sheds. A basic, simple storage idea is to use a bucket caddy with cloth pockets that wraps around a |
5-gallon bucket. It's convenient for storing small tools and you can dump weeds in the bucket. Another idea for keeping small tools, seeds, sunscreen and other items handy is to |
Scientists find trick to reverse moral opinions (CBS News) A new study finds that a person's moral compass is surprisingly easy to throw off. With nothing more than a clipboard, a survey and a small patch of glue, researchers were |
able to get participants to not only subconsciously change their minds but even argue the opposite of their original opinions. The study, led by Lars Hall of Sweden's Lund University, asked 160 volunteers to fill out a quick 2-page survey |
on moral principles and the morality of current events - such as the Israeli-Palestinian conflict. Unbeknownst to the participants, a patch of glue was stuck to the back of the survey clipboard. When flipping to the second page, the top |
set of statements would stick to the back of the clipboard, revealing a different set of questions but leaving the responses unchanged. Published in the journal PLoS One, the study slightly altered the hidden statements to mean the opposite of |
what they said originally. One example used in the study: "Large-scale governmental surveillance of e-mail and Internet traffic out to be forbidden as a means to combat international crime and terrorism." When the hidden statements were revealed, the original had |
been reworded from "forbidden" to "permitted." Participants then read the statements aloud, including the ones that had been altered, and explain their opinions. Researchers found that half of participants did not detect any changes to the statements, and a full |
69 percent accepted at least one of the altered statements. Not only were the volunteers unlikely to spot the changes, 53 percent argued in favor of the altered statements rather than their original opinions. Hall and his team have studied |
this phenomenon previously, calling it "choice blindness." "I don't feel we have exposed people or fooled them," Hall told the journal Nature. "Rather this shows something otherwise very difficult to show, [which is] how open and flexible people can actually |
be." The study may have ramifications concerning the accuracy of self-report questionnaires. Hall believes that standard surveys "are not good at capturing the complexity of the attitudes people actually hold." Liane Young, a psychologist at Boston College who was not |
involved in the study, called the results "intriguing." "These findings suggest that if I'm fooled into thinking that I endorse a view, I'll do the work myself to come up with my own reasons," she told Nature. © 2012 CBS |
Mexico scrambles to cope with egg shortage A city worker sells eggs at government subsidized prices as people line up outside the city truck in Mexico City, Friday, Aug. 24, 2012. The Mexican government is battling an egg shortage and hoarding that have caused prices to spike in a country |
with the highest per-capita egg consumption on earth. About 11 million chickens were slaughtered after a June outbreak of bird flu. / AP Photo/Alexandre Meneghini (AP) MEXICO CITY - The Mexican government is battling an egg shortage and hoarding that have caused prices to spike in a country with the |
highest per-capita egg consumption on Earth. A summer epidemic of bird flu in the heart of Mexico's egg industry has doubled the cost of a kilo (2.2 pounds), or about 13 eggs, to more than 40 pesos ($3), a major blow to working- and middle-class consumers in a country that |
consumes more than 350 eggs per person each year. That's 100 more eggs per person than in the United States. Egg prices have dominated the headlines here for a week, spurring Mexico City's mayor to ship tons of cheap eggs to poor neighborhoods and the federal government to announce emergency |
programs to get fresh chickens to farms hit by bird flu and to restock supermarket shelves with eggs imported from the U.S. and Central America. The national dismay over egg prices has revealed the unappreciated importance of a cheap, easy source of protein that's nearly as important to Mexican kitchens |
as tortillas, rice and beans. Added boiled to stewed chicken, raw to a fruit-juice hangover cure and in every other conceivable form to hundreds of other foods, the once-ubiquitous egg has disappeared from many street-side food stands and middle-class kitchens in recent days. "Eggs, as you know, are one of |
Mexicans' most important foods and make up a core part of their diet, especially in the poorest regions of the country," President Felipe Calderon said Friday as he announced about $227 million in emergency financing and commercial measures to restore production and replace about 11 million chickens slaughtered after t... |
June outbreak of bird flu. Calderon said he was sending inspectors to stop speculation that he blamed for high egg prices, which have almost single-handedly driven up the national rate of inflation. He said that the government had already begun large-scale importation of eggs and that about 3 million hens |
were being sent to farms hit by the flu outbreak. The Mexico City government has sent a refrigerated trailer-truck of eggs into working-class neighborhoods over the last three days, selling kilo packets for less than half the current market price. Several thousand people lined up for about two hours Friday |
morning to buy eggs from the truck in southeastern Mexico City's Iztacalco neighborhood. Isidro Vasquez Gonzalez, an unemployed 43-year-old cook, waited with his niece and nephew to buy three kilos of eggs that they said they would eat almost immediately in a lunch of meatballs with chopped eggs. "You can |
make eggs with anything scrambled eggs, with pork rinds, eggs with beans, green chiles, poached eggs, green beans with eggs, eggs with tomato sauce, " Vazquez said, with a wistful look in his eyes. "People here eat a lot of eggs. They were the cheapest, but now they're the most |
expensive. They're more expensive than meat." The crisis began with the June detection of bird flu in the western state of Michoacan, which produces roughly half of Mexico's eggs. Some 11 million birds were killed to prevent the spread of the disease, sharply cutting into the national supply of more |
than 2 million tons of eggs a year. Government officials blame speculators in the wholesale egg business for driving up prices beyond the hike resulting from bird flu. After existing stocks of eggs ran out, prices rose sharply in August. "Eggs are what we eat the most these days," said |
Gertrudis Rodriguez, 68. But with the higher prices, she said, "if we eat beans, we don't eat eggs, or if we eat eggs, we don't eat beans with them." Mexico City's public Food Supply Center, which provides government-subsidized fresh food to low-income residents, dropped other ingredients from its truck this |
week in favor of eggs, and will distribute 18 tons by the time its current stocks run out Monday, director-general Raymundo Collins said. Calderon said more than 150 tons of eggs had already crossed the border from the U.S. and 100 trailers carrying 500 more tons would arrive in the |
country over the weekend. "The federal government will keep using every tool in its power to keep family's quality of life from being eroded by unfair increases in the price of eggs," the president said.

Strategic Plan - Disabilities & Disparities Priority: Identifying and reducing disparities in key health indicators, including obesity, among children, youth and adults with disabilities. What is the Problem? - Obesity |
rates for children and adults with disabilities are 38 percent and 57 percent higher than rates for children and adults without disabilities. - Adults with disabilities engage in physical activities |
on a regular basis approximately half as often as adults without disabilities (12 percent vs. 22 percent). - Disparities have been found in access to health care, with 29 percent |
of people with disabilities showing unmet need compared to 12 percent of people without disabilities. What Do We Know? The growing body of research on the link between obesity and |
disability indicates that, for both children and adults, those at greatest risk for obesity have mobility limitations, intellectual/learning disabilities, or both. Whether obesity is the result of disability or a |
contributing factor to disability, children, youth and adults with disabilities are an important subgroup to address in reducing obesity in the United States. Reasons for these disparities include: - Lack |
of healthy food choices for many people with disabilities living in restrictive environments; - Difficulty with chewing or swallowing food; - Use of medications that can contribute to changes in |
weight and appetite; - Physical limitations that can reduce a person’s ability to exercise; - Pain and/or lack of energy; - Lack of accessible environments such as sidewalks, parks, and |
exercise equipment; and - Lack of resources such as money, transportation, and social support from family, friends, neighbors, and community members. What Can We Do? Now is the time for |
action. Evidence shows that regular physical activity and good nutrition provide improved cardiovascular and muscle fitness, enhanced mental health, and a better ability to perform tasks of daily life for |
people with disabilities. We need: research to build the evidence for interventions; effective communication to inform stakeholders; and implementation of public health programs, policies, and practices to reduce the disparity |
in obesity and other health indicators such as health care access. With our partners, we are integrating disability into national efforts that address obesity and other health conditions, and identifying |
and measuring outcomes for persons with disabilities to evaluate effectiveness and monitor change. Learn more about disabilities Learn more about NCBDDD’s strategic plan and priorities. - Centers for Disease Control |

Announcements: World Stroke Day — October 29, 2012 Monday, October 29, is World Stroke Day 2012. Approximately 795,000 strokes occur annually in the United States. One of the leading causes |
of disability, stroke occurs among all age groups, including newborns, children, young adults, and older adults (1). One in six persons worldwide will have a stroke in his or her |
lifetime, and every 6 seconds someone will die from a stroke (2,3). Although stroke is a common disease, it can be prevented. In addition, with timely care and support, most |
stroke survivors can recover and regain their quality of life. Everyone should take the following actions to reduce their likelihood of having a stroke: 1) know your personal risk factors, |
including high blood pressure, diabetes, obesity, high blood cholesterol, atrial fibrillation, and a history of having a transient ischemic attack or previous stroke; 2) engage in physical activity regularly; 3) |
maintain a healthy diet high in fruits and vegetables; 4) limit alcohol consumption; 5) avoid cigarette smoke (if you smoke, seek help to stop now); and 6) learn to recognize |
the warning signs of a stroke,* and call 9-1-1 right away if you think someone is having a stroke. CDC addresses stroke prevention through state-based programs to prevent heart disease |
