Solid Advice For Your College Career

College is an important part of a successful life and it is important to do well. The tips shared here with you will help you understand what to expect from college in order to make it easier for you. Pay close attention: you need this info!

When in college, become an intern. You can get a chance to experience what you will be doing after college. If things go well, you may even be offered a job. Your college has a career center that can help you find an internship, as well.

Take time to build friendships. However, just attending first classes a few minutes early is enough to put a good foot forward. You can help students that ask if this classroom is the right place. This is also an easy way to break the ice and develop friendships.

Living in a dorm with a roommate is more affordable than many other alternative housing arrangements. Remember that your surrounding environment can affect your college success. You will find that staying in a dorm is fun, but you might get more work done if you live on your own or with your parents.

You should take time to have fun if you are in college. However, you should not be a party animal. Spend your weekends with friends outside, at the movies, or even at an art gallery.

Take many different electives. As you branch out, you will be able to figure out what drives you. Freshman year of college is the perfect time to try new things and gain new experiences.

Be open-minded when dating. Skip the costly restaurant meal and light candles to give a home cooked meal a special touch. It is not only romantic, but inexpensive too. Get rid of the roommates for the night. You can take turns spending the night elsewhere so you each have some privacy.

Be sure to plan plenty of time for shut-eye when you are making plans for how to budget your time at college. Partying will only lead to missed assignments. Planning in advance helps to yield success in the future.

Attend all orientation events, including social outings. These events can bring you together with others that are in a similar position. However, getting to know new people as soon as possible can help alleviate these fears.

If you are going out of state for, think long and hard about taking your car with you. In heavily populated cities, you may have difficulty finding a free parking space. This can also bring in heavy costs related to insurance, gas and other vehicle related expenses. This can be difficult if working is not an option.

College towns are often very friendly to walkers, cyclists and those willing to use public transportation. Think twice about bringing your vehicle to school with you. Cars are costly to own and parking can be difficult. They can also be time consuming in terms of care and maintenance. If you want to get the most out of school without the worry of a vehicle, learn about public transportation.

Your classes aren't the be-all and end-all of college. Get yourself involved around campus. Get a job or join a student organization. You are always sure to find a broad array of activities taking place on campus. You should try some new things, you might find a new hobby or passion.

You should always schedule a visit to admissions when you are trying to find a college. That way, you can determine whether there are scholarship options specific to the school. There are quite a few college scholarships to be had. Make sure to talk to someone from the financial aid or admissions department to find out about financial aid available to you.

Become involved with extracurricular activities while away at school. The more activities in which you are involved that relate to your interests, the more impressive your resume will look when you graduate. You should never spread yourself too thin and maintain a good GPA, that is the most important thing you can do.

Don't be shy about wearing school colors and showing school pride. Showing a sense of school spirit and sharing it with those around you creates a sense of camaraderie. This ensures you're on the ball at all times.

Going to college is a big decision, and one that will help you to feel successful and accomplished later in life. Always keep your eyes on the prize and work hard until the day arrives when you finally have that diploma.

Mars might still harbor life, say scientists

Liquid water might flow seasonally at some places on Mars, potentially supporting microbial life, say some researchers.

By Rod Pyle,?SPACE.com / February 25, 2013

NASA's Hubble Space Telescope snapped this shot of Mars on Aug. 26, 2003, when the Red Planet was 34.7 million miles from Earth. The picture was taken just 11 hours before Mars made its closest approach to us in 60,000 years.

While Mars was likely a more hospitable place in its wetter, warmer past, the Red Planet may still be capable of supporting microbial life today, some scientists say.

Ongoing research in Mars-like places such as Antarctica and Chile's Atacama Desert shows that microbes can eke out a living in extremely cold and dry environments, several researchers stressed at "The Present-Day Habitability of?Mars" conference held here at the University of California Los Angeles this month.

And not all parts of the Red Planet's surface may be arid currently ? at least not all the time. Evidence is building that liquid?water might flow seasonally?at some Martian sites, potentially providing a haven for life as we know it.

"We certainly can't rule out the possibility that it's habitable today," said Alfred McEwen of the University of Arizona, principal investigator for the HiRise camera aboard NASA's Mars Reconnaissance Orbiter spacecraft. [The Search for Life on Mars: A Photo Timeline]

Surface water on Mars?

McEwen discussed some intriguing observations by HiRise, which suggest that briny water may flow down steep Martian slopes during the local spring and summer.

Sixteen such sites have been identified to date, mostly on the slopes of the huge Valles Marineris canyon complex, McEwen said. The tracks seem to repeat seasonally as the syrupy fluids descend along weather-worn pathways.

While the brines may originate underground, Caltech's Edwin Kite noted, there is an increasing suspicion that a process known as deliquescence ? in which moisture present in the atmosphere is gathered by compounds on the ground, allowing it to become a liquid ? may be responsible.

Astrobiologists are keen to learn more about these brines, for not much is known about them at the moment.

"Briny?water on Mars?may or may not be habitable to microbes, either from Earth or from Mars," McEwen said.

Hardy microbes

Martian life?may be able to survive even in places where water doesn't seep and flow, some scientists stressed.

For example, microbes here on Earth make a living in the Atacama and the dry valleys of Antarctica, both of which are extremely cold and arid, said Chris McKay of NASA's Ames Research Center in Moffett Field, Calif.

Antarctic sites also receive seasonally high ultraviolet radiation doses thanks to a hole in the ozone layer that tends to develop every August through November. This provides yet another parallel to Mars, whose thin atmosphere and lack of a protective magnetic field make the planet more radiation-bombarded than Earth.

In the Antarctic dry valleys, McKay said, organisms dwell within rocks, just deep enough to be shielded from the worst of the UV but close enough to the surface to receive the benefits of photosynthesis. Something similar might be happening on Mars today, if life ever evolved there.

McKay also discussed deliquescence, which in the Atacama allows salts to gather enough water to support the existence of life.

McKay offered some advice to NASA's?Mars rover Curiosity, which landed in August to determine whether Mars could ever have supported microbial life: "Watch for salt along the road!"

A possible energy source

A number of presenters spent some time talking about perchlorate, a chlorine-containing chemical that NASA's Phoenix lander spotted near the Martian north pole in 2008.

McKay and other researchers think perchlorate may be the reason that NASA's twin Viking landers didn't detect any organic compounds ? the carbon-containing building blocks of life as we know it ? on the Red Planet back in the 1970s.

The Vikings vaporized Martian soil and looked for any organics boiling off. They found nothing but a few chlorine compounds that were attributed to contamination. But after Phoenix's perchlorate find, McKay and some other researchers performed an experiment.

They added perchlorate to some desert dirt from Chile known to contain organics. They heated the soil up and found the same chlorine compounds the Vikings did, suggesting that organics may have been present in the Vikings' samples but were broken down by the combination of heat and perchlorate.

While this backstory is interesting in its own right, perchlorate is also relevant to the possible habitability of present-day Mars.

"Perchlorate, it turns out, is a potent chemoautotrophic energy source," said Carol Stoker, also of NASA Ames, noting that the chemical could potentially sustain microbes in the dark?Martian subsurface, where photosynthesis is not an option.

And some Earth microbes use perchlorate for food, so that could be happening on Mars as well, scientists have pointed out.

"The Present-Day Habitability of Mars" took place Feb. 4-5 and was co-hosted by the NASA Astrobiology institute and the UK Centre for Astrobiology. Archived videos of conference presentations are?available here.

Oreo Separator Machine: Modern-day Robert Oppenheimer splits the Oreo

Oreo Separator Machine: Scientist?David Neevel doesn't much care for the creme inside Oreo cookies. So he did what any man with too much time on his hands would do: He invented a revolutionary technology.

By Eoin O'Carroll,?Staff / February 27, 2013

It's a basic human desire to separate an OREO cookie. Humans love either cookie or creme. And sometimes a man just needs to invent a machine to do the hard work of separating the two. Today, that man is physicist and cookie-part preferrer David Neevel. Watch him operate the machine he created that separates OREO cookies.

Once every several generations, an invention comes along that fundamentally alters the course of human civilization. For those living in the 15th century, it was Gutenberg's printing press, which enabled a rapid dissemination of knowledge that ushered in the Protestant Reformation, the Age of Enlightenment, and the Scientific Revolution. In the 18th century, it was the steam engine, which set in motion the Industrial Revolution and its attendant social upheavals.

Today, it's the Oreo Separator Machine, which removes unwanted creme from Nabisco's iconic?sandwich?cookie.?

Developed by physicist and copywriter David Neevel in Portland, Ore. over the course of "0.04 years" ? which is how scientists express the concept of two weeks ? the OSM uses a hatchet to split the cookie in half. The two halves are transported, Rube Goldberg-style, to a tray where a CNC router removes all remaining traces of the offending creme, all without human intervention.?

Like?Pliny the Elder, Sir Francis Bacon, and Marie Curie before him, Neveel thought nothing of sacrificing his well-being in the pursuit of science. "I didn't get to see my girlfriend or my dog for hours at a time sometimes," Neveel says of his hours spent laboring in Portland's chilly Mad Dog Garage. "And I had to try to find, like, a good sandwich in this part of the city and stuff."

Neevel also added that it was hard to "learn how to build robots and make them work."

Neveel has yet to coin a catchphrase for his invention, which is promoted by Nabisco's "Cookie or Creme?" campaign to celebrate the Oreo's 100th birthday, but he has a few thoughts, including "Let's get that cream out of there," and, "This cream is no good; let's get it off the cookie."?

Kohli, Dhoni hit tons, India 403 for 7

?

Chennai: Virat Kohli smashed his fourth Test hundred, while skipper Mahendra Singh Dhoni hit his sixth as India reached 403 for seven post tea session on the third day of the first cricket Test against Australia here on Sunday.

In reply to Australia?s 380 all out, India put themselves in a good position with Kohli?s patient 107 and Dhoni still playing at 121 not out from 145 balls.

Also notable was the magnificent half-century by Sachin Tendulkar (81).

At the break, Dhoni was holding fort with R Ashwin (3) giving him company.

India scored at a decent pace to be 263 for four at lunch, but after the break, the innings accelerated with Kohli and Dhoni breaking free against an attack that never looked very threatening.

Kohli eventually fell to Nathan Lyon, who was rewarded for his perseverance after grabbing Tendulkar?s wicket in the morning session.

However, the breakthrough came only after Kohli and Dhoni had put on 128 runs for the fifth wicket and that too at rapid a pace.

In info age, Belgian diamond heist is a throwback

(AP Photo/Yves Logghe)

(AP) ? At a time when many robberies take place at the click of a mouse, a group of jewel thieves has shown there's still a potential payoff for old-fashioned criminals willing to use disguises, planning and pluck to nab their loot.

Monday's theft of some $50 million worth of diamonds from the tarmac of Brussels' international airport is a "huge blip on the radar," said retired FBI agent Bill Rehder, who spent more than three decades on Los Angeles' bank robbery squad.

"You can almost liken it to the meteor that hit in Russia," he said, referring to the space rock which exploded last week over the city of Chelyabinsk, injuring hundreds. "These things happen so infrequently, but when they do happen it's a huge story."

It's also the type of story that complicates trends that have seen many crimes ? particularly those targeting banks ? jump from the world of brandished weapons and ransom notes to a universe of Trojan software and password-stealing computer programs.

In several Western countries, robberies have fallen as banks have installed bullet-proof glass, access-control vestibules and cash boxes rigged with paint or glue. Rehder said that, in the United States, tougher sentencing for criminals and societal changes have also led to a drop in bank robberies, which shrank from 8,516 in 2001 to 5,086 in 2011.

That trend has been echoed across the Atlantic, with the British Bankers' Association recording an even more dramatic fall in the number of raids, from 232 to 66 in the same period. Europe-wide figures also show a decrease in the number of bank robberies.

Meanwhile, cybercriminals have stepped in to steal some of the money their gun-wielding colleagues have left behind.

Global figures are hard to come by, but the amounts in play can be huge. In 2010, the FBI announced the unraveling of an online organization that had raked in roughly $70 million through a vast network of hackers, money mules, and front companies. Dozens were arrested across the U.S., Britain, and Eastern Europe.

ATM skimming, in which criminals surreptitiously rig cash machines with card readers and cameras to harvest debit card numbers, is another threat.

Doug Johnson, the vice president of risk management at the American Bankers Association, said that while the average U.S. bank robber could expect to make out with $3,000-4,000 from each theft, a skimmer made 10 times that amount with every successful hit.

Even as criminality mutates to fit the new realities of online finance and cashless wallets, spectacular thefts like the one in Belgium carry a special air of romance, Rehder said.

"This will catch the imagination of the public, no doubt about it," Rehder said, explaining that the use of bogus police vehicles to rob a plane right as it prepared to take off fit right in with the mystique of 1960s heist movies, released long before many of today's online criminals were born.

And security experts said that capers in the vein of "The Thomas Crown Affair" (1968) or "Ocean's Eleven" (1960) ? elaborate schemes involving the surgical extraction of jewels, rare artwork, and cash ? were likely to keep popping up well into the information age.

"As long as we have hard currency and value in precious stones and precious metals, we're going to have people who will try to take it," Rehder said.

Or, as Johnson put it, "it's frankly difficult to create virtual robbery of diamonds."
