Fly toy helicopters with your mind. Be a DJ and shift musical tracks based on how you feel. Wiggle robotic cat ears by increasing your state of calm. Astonishing advances in the ability to harness brain waves have made the fantastic notion of moving and controlling objects with the mind possible. Now neuroscientists are grappling with another challenge: Find a "killer app" that will demonstrate the true potential of tapping into brain waves and ignite the neurotechnology revolution.

I would like to tell you about a remedy for leg cramps or spasms. One evening we were playing cards with some friends, and suddenly my husband bent over with a severe leg cramp. Our host went to the refrigerator, got the jar of pickles and poured 1/4 glass of pickle juice. He told my husband to drink it, and the leg cramps eased almost immediately. Have you ever heard of such a remedy? We have heard from many other readers that pickle juice can ease leg cramps. Scientists at Brigham Young University recently tested this remedy on 10 college students.

One of the holy grails of solar cell technology may have been found, with researchers at UCLA announcing they have created a new organic polymer that produces electricity, is nearly transparent and is more durable and malleable than silicon. The applications are mind-boggling. Windows that produce electricity. Buildings wrapped in transparent solar cells. Laptops and phones - or even cars or planes - whose outer coverings act as chargers. It might even be sprayed on as a liquid. The promise of cheap and easy-to-apply site-generated solar electricity might now be a lot closer to reality.

WASHINGTON — It's a mortgage problem that is likely to intensify as home-owning baby boomers by the millions shift into retirement: Although they may have significant financial assets tucked away in retirement accounts, their diminished monthly incomes may not be sufficient to meet some lenders' hyper-strict underwriting rules. Jim Eberle of McLean, Va., found this out the hard way when he applied to refinance his mortgage. After spending much of his career working for banking industry trade associations in Washington, Eberle, 68, decided to take advantage of this spring's unprecedented low interest rates with a 2.89% adjustable-rate 30-year loan offered by a large Midwestern bank.

WASHINGTON - The Obama administration is proposing to make it easier for illegal immigrants who are immediate family members of American citizens to apply for permanent residency, a move that could affect as many as 1 million of the estimated 11 million immigrants living here illegally. The new rule, which the Department of Homeland Security will post for public comment Monday, would reduce the time illegal immigrants are separated from their American families while seeking legal status, immigration officials said.

As part of a settlement with federal regulators, 13 lenders this week are starting to pay out $3.6 billion to more than 4 million troubled borrowers whose homes were in foreclosure proceedings in 2009 and 2010. A chart released Tuesday by the regulators showed that most of the borrowers would receive $300, the minimum allowed under the settlement terms. The maximum of $125,000 would go to 1,135 borrowers whose homes were seized while they were serving in the military or who were current on their payments.

A newly streamlined government plan to reward homeowners who diligently pay their underwater mortgages is proving a bonanza for banks, which by one estimate may pocket $12 billion in extra revenue by refinancing loans. The revisions to the Obama administration's 3-year-old Home Affordable Refinance Program have yielded mixed results for homeowners, analysts and mortgage professionals say. Some responsible homeowners are indeed getting lower-interest loans despite owing far more than their homes are worth.

Everybody loves lists. Most of those you see in the papers or online tend toward the inconsequential (The Six Best "Fast & Furious" Movies). So here's a list with a bit more gravitas: The five biggest lies you're being told about entitlement programs. Never mind that the very word "entitlement" is a lie. Social Security and Medicare got that name because workers became "entitled" to those benefits by paying into the system. In recent years, however, the term has become distorted to signify benefits people are entitled to without earning them.

Have you ever slathered on sunscreen but somehow managed to miss your nose? Or the back of your hand? Or the tops of your feet? You're not the only one. According to the American Academy of Dermatology, most people apply less than half of the optimal amount of sunscreen, a habit that adds up to a lot of burned patches and uncomfortable rides home from the beach.
