From doctors to pets,bills paid by phoneQuestion: What do Chesapeake & Potomac Telephone Co. and Bob's Lawn Service have in common?Answer: Both are listed as "payees" by customers of Maryland National Bank's home banking service, ScreenPhone.The service, which allows customers to pay their bills by phone, debuted in June. Bank officials had expected customers to use ScreenPhone to pay five or six bills a month, tops -- the mortgage, utilities and maybe a credit card company or two.But nobody ever expected customers to use the ScreenPhone to pay for lawn care, pet services or doctor's bills.

The most detailed pictures ever made of the surface of the sun have revealed unexpected "mountains" of glowing gas. The discovery is forcing theorists to reconsider how the sun's surface features contribute to climate shifts on Earth, 93 million miles away. Images from the new 1-meter-diameter Swedish solar telescope in the Canary Islands show shifting ranges of mountain-like features 125 miles to 280 miles high, and vast fields of flat-topped "mesas" the size of Texas. They're formed near dark sunspots by the upwelling of hot gas from the sun's interior, and shaped by magnetic fields.

Q: Can you explain why my fingers often feel numb and look white when I am out in cold weather or rinse dishes in cold water?A: Your description fits the symptoms of Raynaud's phenomenon, a fairly common condition that particularly affects women less than 40 years old.The arteries in the fingers normally constrict after exposure to cold and sometimes when emotional stress is excessive in people with Raynaud's. Full-blown attacks are characterized by three stages. First, the fingers turn pale as circulation is cut off. Next, they turn blue as a result of blood pooling in capillaries.

A team of Johns Hopkins University scientists is designing what may become the largest, most powerful solar telescope ever flown above the Earth's blurring atmosphere.But this state-of-the-art instrument, designed to help researchers find the cause of violent eruptions on the sun's surface, won't soar into orbit aboard a ground-shaking launcher. A NASA rocket or space shuttle flight might take a decade of planning and cost hundreds of millions of dollars, scientists say.Instead, the telescope and its telephone-booth shaped gondola will fly economy class -- dragged 19 miles above Antarctica by a balloon.
NEW YORK -- Scientists have reported finding strong evidence that Earth's inner core is spinning freely and slightly faster than the rest of Earth, making it virtually a planet within a planet.The scientists, at Columbia University, said the inner core was moving fast enough to lap the surface once every 400 years or so.Such inner freedom has never been reported before for any rocky body or planet in the cosmos.The discovery is expected to advance knowledge of how heat flows through Earth, how its interior evolved over the ages, and how its magnetic field forms and periodically reverses.

Maglev's Benefits for BaltimoreIn his Nov. 6 letter, Kenneth Sands wrote regarding the $900,000 contract to study the feasibility of maglev in Maryland. With all the high technology companies located in our area, we are in a unique position to play a major role in the development of maglev.But Mr. Sands has also raised some valid concerns about maglev which I would like to address.This study we are about to undertake is to evaluate the best route for a maglev to link Washington and Baltimore and to assess various transportation integration issues.

With the spring term just around the corner, Professor George Plitnik is looking forward to donning his wizard outfit again. "I wear it to pass out the syllabus - that really makes an impression," said the Frostburg State University physics instructor, who teaches a class on the science of Harry Potter. Later on in the semester he may masquerade as Severus Snape, using dry ice to create classroom smoke.

When a Virgin Galactic plane designed for space tourism eventually launches, a Johns Hopkins Applied Physics Laboratory experiment studying magnetic activity will be on board. The lab's Electronic Field Measurements instrument will be among a dozen experiments that will enter what is known as the "suborbital" region, about 50 miles above Earth's surface, in a NASA-funded mission. A date has not yet been announced for the flight of Virgin's SpaceShipTwo spacecraft. The experiment seeks to study electromagnetic conditions inside the spacecraft to determine what magnetic fields the craft generates itself, independent of Earth's magnetic field.

The sun, in a periodic show of its force, is shooting off powerful solar flares that disrupt the Earth's magnetic force and could cause power shortages in the Northern United States over the next week and spark a display of the northern lights visible as far south as Maryland.This is a sun storm, and government scientists monitoring it in Boulder, Colo., have classified it as "severe," the category designating the highest degree of force.The last severe solar storm, in March 1989, caused power blackouts in northern New York and Canada.

Merriweather Post Pavilion has announced its first summer concert of 2012. It'll be the indie band Foster the People. The band, out with debut album "Torches," will play June 10. The album has already been certified Gold by the RIAA, which is probably why they're getting to play a stage as big as this one with only one album to their name. Tickets, at $45, are already on sale. O.A.R., which played Merriweather in August, is playing it low key with its first pair of shows next year.
