  • Using your phone to make an ATM withdrawal is faster than using a debit card
  • Mobile ATM transactions are more secure than traditional debit card withdrawal
  • Soon you will be able to use your phone to pay at restaurants and other participating establishments

Banks are revolutionizing the way you withdraw money. Instead of using a traditional debit or credit card at an ATM, you will be able to log into a banking app on your cell phone and order cash up to 24 hours before a transaction.

Financial Services giant FIS announced the innovative mobile banking technology at the Money2020 conference in Las Vegas this week. Three banks have already begun testing the app and hope to launch the services in their ATMs by the end of 2014.

The three participating banks thus far are Wintrust in Illinois, BMO Harris in Chicago, and City National in Los Angeles. FIS announced this week that they have been gaining attention from a number of other large banks as well as smaller institutions about the mobile banking app.
Mary Monahan, of Javelin Strategy & Research, believes that using a cell phone to make cash withdrawals is much safer than using a debit card.

The mystery of a series of strange, knobby pillars of rock that formed in Iceland has been solved.

A creeping lava flow and a stream of water mixed to create hollow, rough pillars that dot the Skaelinger Valley in Iceland. The surprise is that these towers could form at all on land. Until now, researchers thought that whenever water and lava met on land, either explosive steam or pillow-shaped lava formed.

"These had never been observed or described before as features seen on land. They've been described at mid-ocean ridges 2 miles [3 km] under water," said study co-author Tracy Gregg, a geologist at the University at Buffalo in New York.

Chelyabinsk meteorite is 'as old as the solar system', say Russian scientists

Scientists conclude that the asteroid explosion over the Ural Mountains in the early morning of 15 February - which injured 1,500 people - had the force of a nuclear bomb. They have also dated the meteorite to be as old as time itself.

'An analysis of Chelyabinsk meteorite fragments shows that its age practically coincides with that of the solar system, 4.56 billion years,' said Mikhail Marov, deputy head of the planetary research and space chemistry department of the Russian Academy of Sciences' Institute of Geo-Chemistry and Analytical Chemistry. 'In fact, we possess a rock from the time of genesis'.

The explosion was recorded in dramatic photographs by observers, a fact which has aided scientists in understanding the phenomenon. Marov also confirmed earlier speculation that the rock may have had an earlier collision some 290 million years ago as it sped around the universe.

'This is just a theory, we cannot say for certain yet that this event has actually taken place,' he said.

A pair of new studies in the British Medical Journal indicate that individuals who live near a major airport run a higher risk of cardiovascular disease and stroke. In one study, scientists from the Harvard School of Public Health discovered that American zip codes with 10-decibel higher aircraft noise averaged a 3.5-percent higher cardiovascular hospital admission rate for adults aged 65 and older.

In the other study, a team of British scientists looked at the effects of aircraft noise around London's Heathrow airport and found that risks of hospital admissions and deaths due to stroke, heart and circulatory disease were approximately 10 to 20 percent higher in areas with the highest levels of airplane noise compared with the quietest areas.

Previous studies have found a connection between living in a loud environment and risk of high blood pressure, but not many have looked specifically at the risk of cardiovascular disease.

"These findings suggest a possible link between high levels of aircraft noise and risk of heart disease and stroke," said Anna Hansell, lead author of the UK study and a researcher at Imperial College London's School of Public Health.

"The exact role that noise exposure may play in ill health is not well established. However, it is plausible that it might be contributing, for example by raising blood pressure or by disturbing people's sleep," she added.

"The relative importance of daytime and night-time noise also needs to be investigated further."

Honolulu -- An exotic young planet free-floating through the Milky Way galaxy rather than orbiting any star is practically a newborn in cosmic terms, astronomers say.

Dubbed PSO J318.5-22, the planet without a host star is 80 light-years away from Earth and has a mass only six times that of Jupiter. It formed a mere 12 million years ago, researchers said -- a newborn in planet lifetimes.

It was identified from its faint, unique heat signature by telescopes in Hawaii, and found to have properties similar to those of gas-giant planets found orbiting around young stars.

Gainsville, Florida - A dollop of peanut butter and a ruler can be used to confirm a diagnosis of early stage Alzheimer's disease, University of Florida Health researchers have found.

Jennifer Stamps, a graduate student in the UF McKnight Brain Institute Center for Smell and Taste, and her colleagues reported the findings of a small pilot study in the Journal of the Neurological Sciences.

Stamps came up with the idea of using peanut butter to test for smell sensitivity while she was working with Dr. Kenneth Heilman, the James E. Rooks distinguished professor of neurology and health psychology in the UF College of Medicine's department of neurology.

It's the question on every astronomer's mind this season, both backyard and professional: will Comet C/2012 S1 ISON survive perihelion?

Now, new studies released today at the American Astronomical Society's 45th Annual Division for Planetary Sciences meeting being held this week in Denver suggests that ISON may have the "right stuff" to make it through its close perihelion passage near the Sun. This is good news, as Comet ISON is expected to be the most active and put on its best showing post-perihelion... if it survives.

Researchers Matthew Knight of the Lowell Observatory and Research Scientist Jian-Yang Li of the Planetary Science Institute both presented a compelling portrait of the characteristics and unique opportunities presented by the approach of comet ISON to the inner solar system.

Could a comet have caused the Great Chicago Fire of 1871? For three days, October 8-10, 1871, Chicago was burning. It was a rain of fire and terror as the wood buildings burned to the ground.

Ironically, the O'Leary house (Mrs. O'Leary of the famous cow and lantern theory) was left standing on DeKoven Street. The Water Tower also remained. Most of what was then Chicago was in ruins.

At the same time, there were fires burning in other parts of llinois, Wisconsin and Michigan. The Great Peshtigo Fire (in Peshtigo, Wisconsin) is still considered one of the worst natural disasters in U.S. history.

There were also fires in Urbana, Illinois and Holland, Michigan.

Weird shift of Earth's magnetic field explained

Earth's magnetic field_1

Earth's magnetic field shields the planet from charged particles streaming from the sun, keeping it from becoming a barren, Mars-like rock. For more than 300 years, scientists have recorded a westward-drifting feature in the field that models have been unable to explain.

By relying on insights gleaned from previous work, as well as data collected over nearly four centuries, an international team of scientists has been able to provide a model that accounts for the western drift of the magnetic field on one side of the planet.

"People have tried various configurations regarding the state of the core-mantle alignment," lead author Julien Aubert, of the Université Paris Diderot in France, told SPACE.com in an email."The ingredients were here, but they were never put in the right configuration, in particular for reproducing the geomagnetic westward drift."

Every so often, engineers send a spacecraft in Earth's general direction to pick up a speed boost before heading elsewhere. But sometimes, something strange happens - the spacecraft's speed varies in an unexpected way. Even stranger, this variation happens only during some Earth flybys.

"We detected the flyby anomaly during Rosetta's first Earth visit in March 2005," stated Trevor Morley, a flight dynamics specialist at the European Space Agency's European Space Operations Centre in Darmstadt, Germany.

"Frustratingly, no anomaly was seen during Rosetta's subsequent Earth flybys in 2007 and 2011. This is a real cosmic mystery that no one has yet figured out."
