The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization. NAS is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM).
As a national academy, new members of the organization are elected annually by current members, based on their distinguished and continuing achievements in original research. Election to the National Academy is one of the highest honors in the scientific field. Members of the National Academy of Sciences serve pro bono as "advisers to the nation" on science, engineering, and medicine. The group holds a congressional charter under Title 36 of the United States Code.
Founded in 1863 as a result of an Act of Congress that was approved by Abraham Lincoln, the NAS is charged with "providing independent, objective advice to the nation on matters related to science and technology. … to provide scientific advice to the government 'whenever called upon' by any government department."[2]
The Academy receives no compensation from the government for its services.[3]
The Academy currently has 2,984 members and international members. Existing members elect new members for life. Up to 120 members are elected every year; up to 30 foreign citizens may be elected as international members annually. The election process begins with a formal nomination, followed by a vetting period, and culminates in a final ballot at the Academy's annual meeting in April each year. Members are affiliated with a section -- a specific scientific field -- in one of six so-called "classes": (1) Physical and Mathematical Sciences; (2) Biological Sciences; (3) Engineering and Applied Sciences; (4) Biomedical Sciences; (5) Behavioral and Social Sciences; and (6) Applied Biological, Agricultural, and Environmental Sciences.[6] Since its founding, the Academy has elected 6,457 members. Harvard University is associated with the most members (329), some 5% of the all-time total. The top ten institutions, half of which are Ivy League universities, account for nearly 28% of all members ever elected.[11]

Mediterranean home styles are made of stucco, so they’re most common in warm climate states like Arizona and California. These homes grew in popularity in the 1920s and ‘30s after being featured as homes for the rich and famous on the silver screen.
Mediterranean-style homes include Spanish and Italian architectural elements. These key features make them easy to spot:
- Stucco walls painted white or brown
- Classic red tile roofs
- Arched doorways and windows
- Ornamentation including wrought iron, heavy doors, and decorative tiles
Mediterranean homes still carry the feelings of class and luxury they were built with over 100 years ago, with an added element of history and charm.
Modern home design became popular in the early 20th century and has a heavy influence on today’s contemporary designs. The core of modern designs can be seen in their:
- Use of geometric shapes
- Large, floor-to-ceiling windows
- Clean lines and flat roofs
- Open floor plans
These styles attempt to connect with nature through minimalism and fluid design between outdoor and indoor spaces. Modern house styles branch into a few key sub-styles.
Around the 1820s, Americans experienced a renewed interest in classic Greek and Roman culture. This cultural shift was a natural fit for architects, who brought the Greek Revival house style to life.
Greek Revival architecture became popular in homes as well as businesses, banks, and churches. Prominent features include:
- Easy to identify shapes, including a rectangular building and triangular roofs
- Gable-front designs
- Large porches and protected entryways
- Greek-inspired columns both square and round
Greek Revival homes often have decorative trim and moulding around the front door and windows. These ornate features and columns are easy ways to identify Greek Revival architecture.
A French Country home has a rustic yet upscale charm. French Country architecture is designed after French chateaus and became popular with American soldiers returning from World War I.
French Country homes offer a unique house style featuring:
- Steep pitched or hipped roofs
- Tall ceilings and windows
- Traditional materials including clay, stone, and brick offer a rustic appeal
- Exposed wooden beams in ceilings and walls
French Country homes are designed with their environment in mind. They often feature neutral colors with soft, nature-inspired pops of color like sunshine yellows and grass greens.
American popular music has had a profound effect on music across the world. The country has seen the rise of popular styles that have had a significant influence on global culture, including ragtime, blues, jazz, swing, rock, bluegrass, country, R&B, doo wop, gospel, soul, funk, punk, disco, house, techno, salsa, grunge and hip hop. In addition, the American music industry is quite diverse, supporting a number of regional styles such as zydeco, klezmer and slack-key.
Distinctive styles of American popular music emerged early in the 19th century, and in the 20th century the American music industry developed a series of new forms of music, using elements of blues and other genres of American folk music. These popular styles included country, R&B, jazz and rock. The 1960s and 1970s saw a number of important changes in American popular music, including the development of a number of new styles, such as heavy metal, punk, soul, and hip hop. Though these styles were not in the sense of mainstream, they were commercially recorded and are thus examples of popular music as opposed to folk or classical music.
The American Farmhouse is a simple and timeless style. Farmhouses are designed to be practical first and foremost. They’re common across the US and often showcase regional variations, like wrap-around porches in the South.
Farmhouses have evolved with time and location, but often feature these elements:
- Rectangular floor plan
- Large front porches
- Natural wood and stone materials
- Few and small windows
- Formal front rooms separated from family rooms
Of course, the easiest way to identify a farmhouse is that they’ll often be situated on a large plot of farmland.
Mid-century Modern designs are nothing new and have influenced interior design, graphic art, and house styles. Mid-century Modern homes are designed to embrace minimalism and nature. They’re also often modeled to appeal to a futuristic or abstract concept.
Mid-century Modern homes can be identified by their:
- Flat planes and clean lines
- Monochromatic brickwork
- Asymmetrical home layouts
- Nature-inspired interior
- Interior level shifts between rooms
Mid-century architecture is still widely popular today, as are Mid-century Modern interior design and furniture trends.
1. From this valley they say you are going, I will miss your bright eyes and sweet smile, For they say you are taking the sunshine, that brightens our pathways awhile. (CHORUS) Come and sit by my side if you love me, do not hasten to bid me a-dieu, but remember the Red River Valley, and the cowboy who loved you so true.
2. I’ve been thinking a long time, my darlin’, Of the sweet words you never would say, now, alas, all my fond hopes must vanish. For they say you are going away. Repeat Chorus: Come and sit by my side if you love me, do not hasten to bid me a-dieu, but remember the Red River Valley, and the cowboy who loved you so true.
3. Do you think of the valley you’re leaving? Oh, how lonely and sad it will be! Do you think of the kind hearts you’re breaking, and the pain you are causing to me? Repeat Chorus: Come and sit by my side if you love me, do not hasten to bid me a-dieu, but remember the Red River Valley, and the cowboy who loved you so true.
4. I have promised you, darlin’, that never, will a word from my lips cause you pain; And my life, it will be yours forever If you only will love me again. Repeat Chorus: Come and sit by my side if you love me, do not hasten to bid me a-dieu, but remember the Red River Valley, and the cowboy who loved you so true.
There was a renewed interest in handcrafted art and design following the industrial revolution. This became the “Arts and Crafts” era and paved the way for the Craftsman home, or “arts and crafts” home.
Craftsman homes focus on simplicity to counter the ornate stylings of Victorian homes. They’re also designed to highlight the craftsmanship of its builders and include:
- A low-pitched roof with overhanging eaves
- A covered porch
- Woodwork including exposed beams and built-in features like shelving
- Natural tones to complement the warmth from woodworking
Craftsman homes are favored for their character and are another versatile style that may borrow common elements from other home styles.
Shingle-style homes took influence from Colonial architecture rather than Medieval Europe. Ornamentation became simpler towards the end of the Victorian-era and Shingle-style homes are best known for their creative floor plans and signature shingles on exterior walls.
Shingle Victorian homes are identified by these interior and exterior features:
- Shingles cover the entire exterior
- Asymmetrical interior layouts without a central hallway
- Emphasis on horizontal planes
- Custom built to meld with the nature surrounding the house
Shingle-style houses were designed as a work of art and encouraged creativity in their use of shapes and features.
House styles will continue to evolve with influences from history, culture, and our lifestyles. All of these house styles can be seen and celebrated across the US and have their own stories to tell. Choose the house style that fits your lifestyle, location, and, of course, personal style best. Then check your credit score, get pre-approved, and start house-hunting.
The U.S. health system is a mix of public and private, for-profit and nonprofit insurers and health care providers. The federal government provides funding for the national Medicare program for adults age 65 and older and some people with disabilities as well as for various programs for veterans and low-income people, including Medicaid and the Children’s Health Insurance Program. States manage and pay for aspects of local coverage and the safety net. Private insurance, the dominant form of coverage, is provided primarily by employers. The uninsured rate, 8.5 percent of the population, is down from 16 percent in 2010, the year that the landmark Affordable Care Act became law. Public and private insurers set their own benefit packages and cost-sharing structures, within federal and state regulations.
The Pueblo Revival was inspired by the indigenous Pueblo people’s architecture in the Southwestern US. Pueblo homes were made of adobe or stucco and designed to handle the extreme temperatures of the desert.
Architects in California began to explore the Pueblo style in the late 19th century and the Pueblo Revival style spread across New Mexico, Arizona, and Colorado.
The Pueblo Revival hit its peak in the 1930s in Santa Fe, and these Pueblo-style elements are still popular in the Southwest:
- Rounded corners and irregular shapes
- Earth tones that reflect the desert colors
- Stepped effects with higher floors becoming smaller
- Flat roofs with parapet trim
- Exposed roof beams extending past the walls
The Pueblo Revival style is also commonly called Adobe or Santa Fe style architecture.
