UnitedHealthcare wants you to know the facts about sickle cell

UnitedHealthcare wants you to know the facts about sickle cellSickle cell disease is the most common inherited blood disorder in the United States. The disease affects 70,000 to 100,000 Americans and is most prevalent among African Americans, according to the National Center for Health Statistics. About one in 500 African Americans has the disease, and one in 12 carry the sickle cell trait.

They often form clumps, which can slow or block blood flow and oxygen throughout the body causing pain, serious infections, and organ damage.

Home Solar Energy

Home Solar EnergyDear EarthTalk: Is it now feasible to provide all of a home’s energy needs—including air conditioning—with solar power alone? If so, why hasn’t solar caught on more, particularly in U.S. “Sun Belt” states from southern California east to Florida? -- Tim Douglas, Burlington, VT

It has been possible for years if not decades to provide all of a home’s energy needs with solar power. The technology is here and is only getting more efficient and less obtrusive every day. The only real stumbling block is cost: Solar systems capable of meeting all of an average U.S. home’s energy needs start at around $25,000. Given how inexpensive the grid-based power we now get all across the country remains—and, bear in mind that many utilities are working more and more renewable energy sources, like wind power, into their mix—going solar alone just doesn’t pencil out economically for most people.

Genetically modified foods

Genetically modified foodsDear EarthTalk: As far as I know, genetically modified foods are not required to be labeled so. Why is this? Don’t we have a right to know what our food is made of? -- Rebecca Webster, via e-mail

Unbeknownst to most Americans, a majority of the processed foods available in grocery stores today are derived from genetically modified (GM) sources—whereby genes have been taken from one species and insert into another to obtain specific traits or characteristics. Given how new GM technology is—scientists first began tinkering with it in the 1970s but only recently began utilizing it on a wide scale across the food sector—the jury is still out as to whether such products can cause health or environmental problems.

But critics of such privatization point out that the end result for consumers is not always so positive.
