WASHINGTON — It's finally time to reclaim that hour of sleep you lost last spring.

Most of the country will turn back the clocks this weekend for the annual shift back to standard time.

The majority of folks will do the switch before hitting the sack Saturday night, even though the change doesn't become official until 2 a.m. Sunday local time.

Residents of Hawaii, most of Arizona and some U.S. territories don't have to change since they do not observe daylight-saving time.

Public safety officials say this is also a good time to put a new battery in the smoke alarm, no matter where you live.

Daylight saving time returns the second Sunday in March.

  • 7. Medical Scientists, Except Epidemiologists

    <strong>Percent increase:</strong> 36.4 percent <strong>Total new jobs (2010-2020):</strong> 36,400 <strong>Median income:</strong> $76,700 <strong>States with the most jobs per capita:</strong> Massachusetts, California, Washington Though the roles of medical scientists vary from job to job, all study biological systems to understand their effects on human health. Medical scientists often work for the federal government, at research universities or in the private sector. By 2020, the number of medical scientists is projected to increase to more than 136,000, as the population of the United States grows and ages and the demand for prescription drugs rises. Educational requirements are quite high, with most positions asking for either a doctorate or a medical degree. The annual pay of the top 10% of medical scientists was $142,800. <a href="http://247wallst.com/2012/08/30/the-best-paying-jobs-of-the-future-2/#ixzz258VQKtNN" target="_hplink">Read more at 24/7 Wall St. </a>

A doctoral degree is necessary, as is a state license, though exact requirements differ by state. Explaining projected job growth, the BLS notes that "hearing loss increases as people age, so an aging population is likely to increase demand for audiologists." There are not very many audiologists, and a projected 36.8 percent increase in jobs would bring the total number of audiologists to 17,800 by the end of the decade. Annual salaries exceeded $102,210 for the top 10 percent of audiologists. <a href="http://247wallst.com/2012/08/30/the-best-paying-jobs-of-the-future-2/#ixzz258VQKtNN" target="_hplink">Read more at 24/7 Wall St. </a>

These jobs often require a great deal of technical knowledge in fields such as biology, engineering, math and chemistry. Because of this, a bachelor's degree is typically needed. The professional requirements come with impressive compensation. The median income for such jobs was $81,540 and the top 10 percent earned more than $126,990. Between 2010 and 2020, the number of biomedical engineers is projected to rise by 61.7 percent, more than four times the projected growth rate for all jobs, which is 14 percent. To explain its growth projections for the profession, the BLS cites the baby boomer generation's growing demand for biomedical devices and procedures as it "seeks to maintain its healthy and active lifestyle." <a href="http://247wallst.com/2012/08/30/the-best-paying-jobs-of-the-future-2/#ixzz258VQKtNN" target="_hplink">Read more at 24/7 Wall St. </a>
