Nasa Essay, Research Paper  National Aeronautics and Space Administration (NASA) NASA The era of space exploration began in 1957, when the Soviet Union launched the first satellite, Sputnik, into Earth orbit October 4, 1957. The Soviet also were the first to launch a manned spacecraft when Yuri Gagarni, made one orbit around the Earth in 1961. Americans were electrified by the news. A year later the Soviets issued an ultimatum that the Western Allies evacuate Berlin. Next came a proposal that Berlin become a free city. There waere fears that the Cold War of coexistence could turn into a world war. America also had goals they wanted to fulfil. A year later the United States Congress passed the National Aeronautics and Space Act to promote and coordinate the United States

space program. In 1958 the National Aeronautics and Space Administration was established, commonly referred to NASA. Shortly after NASA s founding, the launching site at Cape Canaveral, Florida, and the Johnson Space Center in Houston Texas were planned and built. Thus creating the space race. According to the 1958 act, NASA s functions are: to conduct research on problems of flight within and outside the Earth s atmosphere; to develop, construct, tests and operate space vehicles; to explore space with manned and unmanned vehicles; to cooperate with other nations on projects for the peaceful uses of space; and to publish the results of its work. The planning and control of NASA s activities take place at the agency s headquarters in Washington, D.C. There are four program

offices that have been set up to develop and direct the activities of NASA s several field installation: Office of Aeronautics and Space Technology, Office of Space Science and Applications, Office of Space Flight, and Office of Space Tracking and Data Systems. The Office of Aeronautics and Space Technology is responsible for the continued development of advanced technology. This office set the guidelines for NASA s objectives, demonstrates the feasibility of the objectives, and proposes the necessary technology to carry them out. It also coordinates activities with other agencies to prevent duplication of effort. The office of Space Science and Applications directs the study of the nature of the universe through research in astrophysics, biology, Earth sciences, solar system

exploration, communications, micro gravity, and information systems. This office uses a vairety of devices to conduct its research. These include remote sensing equipment, automated spacecraft, sounding rockets, balloons, and aircraft. The Office of Space Flight is responsible for the space laboratories and all facets of the Space Transportaion System, or space shuttles of NASA. This office also directs several of the field installations and oversees the purchase of all hardware necessary for NASA s space programs. The office of Space Tracking and Data Systems Provides all the information necessary for the commencement and progress of space missions. The facilities that provide this information support are the Deep Space Network, the Space flight Tracking and Data Network, and

the Tracking and Data Relay Satellite systems. A global communications system coordinates the tasks of this office by linking all tracking sites, control centers, and data processing facilities.NASA has nine chief field installations. Many people who follow space launches know of the Lyndon B. Johnson Space Center in Houston, Tex. and the John F. Kennedy Space Center at Cape Canaveral, Fla. The Houston installation is a command control center, while the center at Cape Canaveral is the primary launching site. The other field installations are: Ames Research Center at Moffet Field, Calif.; Goddard Space Flight Center in Greenbelt, Md.; the Jet Propulsion Laboratory in Pasadena, Calif.; Langley Research Center in Hampton, Va.; Lewis Research Center in Cleveland, Ohio; George C.

Ovarian cancer cells nurtured in microgravity conditions are three-dimensional, much closer in true size and form to natural tumor cells found in cancer patients. Multicellular clusters like these can reach diameters of 0.4 centimeters. (University of South Florida)

Conventional two-dimensional culturing techniques produce a flat, uniform layer of ovarian tumor cells, as seen here under an electron microscope. This growth pattern does not reflect the way tumor cells grow naturally within a human body. (University of South Florida)

The objective of NASA's biotechnology cell science research aboard the International Space Station is to provide a controlled environment for the cultivation of cells into healthy, three-dimensional tissues that retain the form and function of natural, living tissue.

As normal human cells grow and replicate, they form complex "colonies" of fibers, proteins and other structures that make up living tissue. Studying this mechanism outside the human body is difficult, however, because cells do not easily associate to form these cellular colonies outside living organisms. Most cultivated cells form flat, thin specimens that offer only limited insight into the way cells work together. Scientists were excited, therefore, to discover that cells grown in microgravity -- the low-gravity environment inside spacecraft orbiting the Earth -- much more closely resemble those found in our bodies here on Earth.

Cell cultures are maintained in stationary or rotating "bioreactors," which provide the environmental and metabolic support necessary for cell growth. Bioreactor cell growth in a microgravity environment permits cultivation of in vitro tissue cultures of sizes and quality not possible on Earth. Such a capability provides unprecedented opportunities for breakthrough research in the study of human diseases, including various types of cancer, diabetes, heart disease and AIDS.

Cellular Biotechnology Program Overview

The Cellular Biotechnology Program at the Johnson Space Center uses NASA cell culture technology and the microgravity of space to advance ground-breaking research in biomedical science. The Program emphasizes research in:

  • Tissue engineering for research, transplantation and biopharmaceutical production
  • Tissue production for modeling diseases such as cancer
  • Vaccine production through propagation of microorganisms
  • Space biology as it relates to the transition of terrestrial life to low-gravity environments and to the exploration of space

Our investigator community extends throughout the country and includes research organizations such as the National Institutes of Health, headquartered in Bethesda, Md.

The Cellular Biotechnology Program develops ground-based and space bioreactors and support systems required for flight investigators' cell culture investigations aboard orbiting spacecraft such as the Space Shuttle, and the International Space Station. The Space Station Biotechnology Facility, scheduled to be carried to the Station in 2006, will be a complete research laboratory facility with static and rotating-wall bioreactors, analytical equipment for on-orbit analysis, systems for supplying gas mixtures to bioreactors and for low temperature stowage, computer systems and software to control and monitor facility and experiment hardware and for transmitting experiment data back to Earth.

The Cellular Biotechnology Operations Support System (CBOSS) is designed as an interim platform for cell-based research aboard the Space Station prior to the launch of the permanent Biotechnology Facility. The system is comprised of sub-rack modules that provide semi-automated bioreactors, gas supply systems, computer control systems and passive and low-temperature stowage systems. The system will enable investigations on normal and cancerous mammalian cells, including ovarian and colon cancer cells, neural precursor and human renal cells.

CBOSS will be launched aboard STS-105 and transferred to the orbiting facility as part of Space Station Expedition Three. The system is comprised of the Biotechnology Specimen Temperature Controller (BSTC), the Biotechnology Refrigerator (BTR), the Gas Supply Module (GSM) and the Biotechnology Cell Science Stowage (BCSS).

The Biotechnology Specimen Temperature Controller can house 32 stationary tissue culture modules, operating at 56 watts of power during incubation to maintain the modules at a specified temperature in a controlled atmosphere. This unit, designated BSTC-303 is a modified version of the hardware that flew on the STS-86 (Mir NASA Increment 6) and STS-90 missions. Modifications include: the conversion from four small chambers to a single, large incubation chamber, the addition of a gas purge system, carbon dioxide monitoring, and a TCP/IP Ethernet connection to communicate with the EXPRESS Rack's Interface Computer.

The Biotechnology Refrigerator, designated BTR-304, is a thermo-electric, temperature-controlled unit which provides 0.53 cubic feet of on-orbit cold storage at 39.2 degrees Fahrenheit (4 degrees Celsius). Temperature-sensitive cell samples and stowage items are carried in the Biotechnology Refrigerator for launch and return aboard the Space Shuttle. The refrigerator operates on 160 watts and is 10.98 inches by 6.96 inches (27.9 cm by 17.7 cm). This unit is an upgraded version of the BTR-302, which successfully flew and operated aboard missions STS-86 (Mir NASA Increment 6), STS-89 (Mir NASA Increment 7) and STS-91. Modifications to the upgraded unit include an improved cooling system, increased structural strength, reduced power consumption and new data uplink and downlink capability for health and status reporting.

The Gas Supply Module supplies a continuous flow of metabolic gases to the Biotechnology Specimen Temperature Controller to support and maintain the chemical and physiological processes required to sustain cell cultures. The module is conceptually based on a gas supply module designed, flown, and operated aboard Mir from 1996 through 1998. The system is mechanical, requiring no electrical power. Two independent supply lines are available for multiple experiment support, and all four of the unit's gas cylinders can be connected to provide a common supply source. The Gas Supply Module can hold up to 634 quarts (600 liters) of gas when charged to 2,575 pounds psi (181 kilograms per centimeter).

Biotechnology Cell Science Stowage-1 and Biotechnology Cell Science Stowage-4 are stowage units designed to safely and efficiently package and transport cellular biotechnology equipment and materials required to conduct experiments during Flight 7A.1.

The crew is responsible for transferring all systems hardware and stowage from the Shuttle to the designated ISS EXPRESS Racks, as well as installation and activation of the hardware systems.

Once the Cellular Biotechnology Operations Support System is operational, the health and status of the Biotechnology Specimen Temperature Controller and the Biotechnology Refrigerator will be downlinked to the CBOSS operations flight control team at the Johnson Space Center's Telescience Center. The crew will support the experiment by periodic recording of scientific data, adding fresh media to the tissue culture modules and processing samples for return to Earth.

Periodically, the crew will perform preventive maintenance on system components. At the termination of the CBOSS experiments, the crew will deactivate all experiment hardware except the Biotechnology Refrigerator, which will protect and maintain cell samples until their return to Earth.

Though NASA has been dedicated to cellular biotechnology since 1983, cell science research conducted in the environment of microgravity is relatively new. The first experiments flown aboard the Space Shuttle were in the mid-1990s (STS-70, STS-85). Long-duration cellular biotechnology experiments were conducted in the Biotechnology System Facility on the Russian Mir space station from 1996 through 1998.

Cellular Biotechnology research conducted by NASA, its science investigators, and commercial partners has potential benefits and applications: Increased understanding of basic cell biology, as well as the effects of gravity on terrestrial cell biology; Potential production of living, functional replacement tissue for research and medical applications; Identification of new technologies that will advance science on Earth; Determination of potential health remedies and countermeasures for future long term space flight.

NASA signs patent to develop novel biotechnology approaches that could have medical applications

NASA signs patent to develop novel biotechnology approaches that could have medical applications

Published on February 10, 2014 at 6:56 AM

NASA has signed two patent license agreements with GRoK Technologies LLC of Houston to help develop novel biotechnology approaches that could have multiple applications in space and on Earth. The agreements are the results of the agency's Technology Transfer Program, which helps open up NASA's research and technology to the public for use and development.

The agreements grant rights for four patented technologies invented by NASA and GRoK scientists. NASA is interested in the potential these technologies present for regenerating bone and muscle. During long spaceflights, astronauts are susceptible to developing osteopenia, which is a condition arising from the loss of bone and muscle mass and bone density. The patented technologies could help GRoK develop breakthrough products for the research and medical communities and advance our overall understanding of biomedicine.

"Biotechnology research taking place on the International Space Station and at NASA centers around the country continues to push the leading edge of science," said Yolanda Marshall, director of the Strategic Opportunities and Partnership Development Office at NASA's Johnson Space Center in Houston. "This partnership will further enhance NASA's ability to share the unique breakthroughs made in space-based research."

GRoK will be able to use these patented methods on two platform technologies the company is developing.

The first platform, called BioReplicates, will allow users to create 3-D human tissue models that can be used to test cosmetics, drugs and other products for safety, efficacy and toxicity with greater accuracy, reliability and cost-efficiency. Additionally, using such models may reduce the industry's reliance on animal testing.

The second platform, called Scionic, could lead to the development of medical devices designed to target musculoskeletal pain and inflammation in humans and animals noninvasively and without the use of pharmaceuticals.

"The GRoK team is delighted we are now a NASA licensee with the opportunity to bring forward into the commercial sector technologies that have the capacity to improve the lives of people everywhere," said Moshe Kushman, GRoK's founder and CEO. "It's not just science fiction anymore. All indications are that 21st century life sciences will change dramatically during the next several decades, and GRoK is working to define the forefront of a new scientific wave."

NASA's Technology Transfer Program ensures that technologies developed for missions in exploration and discovery are broadly available to the public, maximizing the benefit to the nation. Making NASA technologies available promotes commercial activity, encourages economic growth, and stimulates innovation in business and commerce.

NASA - NASA biotechnology activities enhancing quality of life - Marshall Center Space News Release H03-209 (06-24-03)

With help from industry and commercial partners across the country, NASA continues to use space research to improve life on Earth. From anthrax-killing devices to artificial bone replacement materials to pharmaceutical drugs, the benefits of studying in space continue to provide advancements in science and technology. Those technologies and others have or are being developed by more than 150 companies — partners with NASA's Space Product Development Program and its 15 Research Partnership Centers.

W hat do an anthrax-killing device, soybeans in space, artificial bone replacement materials, light-emitting diodes for wound healing, a new medicine to treat bone loss, a water bottle that filters out bacteria, a perfume, and advanced techniques for pharmaceutical drug design have in common?

These technologies and others have or are being developed by more than 150 companies that are partners with NASA's Space Product Development Program (SPDP) and its 15 Research Partnership Centers (RPC's) across America.

"Industry is interested in many of the same revolutionary products and technologies that NASA needs to explore the universe," said Mark Nall, director of the Space Commerce Office at NASA's Marshall Space Flight Center (MSFC), Huntsville, Ala. "When industry, academia and NASA come together, industry positions itself for growth in new commercial markets, while academia and NASA benefit from innovative research and technological tools for exploration," he said.

Space and Osteoporosis Research and Treatment

Muscle and bone loss is one health-related problem that both NASA and industry are tackling. Since bone loss occurs more rapidly in space, Amgen, a biotechnology company with headquarters in Thousand Oaks, Calif. used NASA's Space Shuttle as a test bed for a new medication to treat bone loss or osteoporosis. Amgen discovered osteoprotegerin (OPG) in the mid 1990s, and is conducting human clinical trials to evaluate its safety and effectiveness in treating osteoporosis and its ability to maintain bone density in cancer that has metastasized to bone.

"OPG appears to prevent bone loss in a variety of diseases, including cancer, and we anticipate that a drug based on this molecule will be effective in preserving bone mass, whether in astronauts or the millions of Americans suffering from osteoporosis," said Dr. Paul Kostenuik, a research scientist in Amgen's Metabolic Disorders group.

Amgen works with BioServe Space Technologies Inc. a NASA Research Partnership Center at the University of Colorado, which has completed 23 research missions in 12 years on both the Space Shuttle and the International Space Station. BioServe and its industry partners are studying antibiotic production, mammalian cell culture and plant biochemistry.

Crops for Space and Earth

Identifying unique chemical and genetic traits of plants grown in space and using these traits to develop commercial products on Earth is the specialty of another NASA RPC: the Wisconsin Center for Space Automation and Robotics (WCSAR) at the University of Wisconsin in Madison. With the help of astronaut Peggy Whitson, they grew the first crop of soybeans on the Space Station for their industrial partner, Pioneer Hi-Bred International Inc. a DuPont subsidiary with headquarters in Des Moines, Iowa.

This experiment verified that WCSAR-developed plant growth technologies were capable of producing a major agricultural crop in space. The second objective was to see whether microgravity would alter the production of phytochemicals, such as proteins, oils and carbohydrates, and induce new genetic traits in the soybean seeds produced in space. DuPont pursued this research because it could significantly reduce the time and cost of introducing new varieties of crops with new types of phytochemicals to the marketplace.

Scientists are performing tests on the seeds brought back to Earth in October 2002. Some of the soybean seeds produced in space were planted and did prove to be viable, producing a new crop of plants with seeds on Earth. Scientists have found some of the space seeds' phytochemical compositions are different than those in seeds harvested from the ground control experiment. Researchers are continuing their analysis to determine if these changes in composition result in positive changes to seed quality. "We want to examine the seeds produced by plants grown on the Space Station to see if they have any unique, desirable traits," said Dr. Tom Corbin, a research scientist for Pioneer Hi-Bred. "If we find changes, then we want to know if the positive traits can be inherited genetically by future generations of plants for the benefit of farmers and consumers."

This commercial experiment and others that study plant growth are paving the way for improving crops grown on Earth, as well as potentially feeding people living in space. The Space Station gives companies a chance to grow plants that are larger and require several months to mature. Several new products, including an anthrax-killing device, a system derived from an ethylene scrubber that keeps fruits and vegetables fresher when they are stored or transported, wound healing and surgical tools, all evolved from technology that WCSAR originally developed to grow plants on the Space Station.

Drug Discovery Through Space Research

The Center for Biophysical Sciences and Engineering (CBSE), an RPC located at the University of Alabama at Birmingham, partners with industry to enable NASA to stretch research dollars. The CBSE, under the direction of Dr. Larry DeLucas, a payload specialist on Shuttle mission STS-50, is a leading structural biology center with one of the largest facilities in the world for X-ray crystallography, as well as a platform of proprietary high throughput technologies designed for structure based drug discovery.

CBSE has developed a suite of technologies to rapidly determine the biological structures necessary to produce new therapeutics and pharmaceuticals. This research has led to the development of drugs designed to treat various chronic and infectious diseases. The predictive power that comes from molecular research in the drug discovery process can significantly advance the launch of new drugs for the safety and health of humans on earth and those traveling in space.

NASA research gives guideline for future alien life search

NASA research gives guideline for future alien life search September 11, 2014 by William Steigerwald

Right: Ozone, oxygen, carbon dioxide and methane -- without carbon monoxide, indicate a possible true positive. Credit: NASA

Astronomers searching the atmospheres of alien worlds for gases that might be produced by life can't rely on the detection of just one type, such as oxygen, ozone, or methane, because in some cases these gases can be produced non-biologically, according to extensive simulations by researchers in the NASA Astrobiology Institute's Virtual Planetary Laboratory.

The researchers carefully simulated the atmospheric chemistry of alien worlds devoid of life thousands of times over a period of more than four years, varying the atmospheric compositions and star types. "When we ran these calculations, we found that in some cases, there was a significant amount of ozone that built up in the atmosphere. despite there not being any oxygen flowing into the atmosphere," said Shawn Domagal-Goldman of NASA's Goddard Space Flight Center in Greenbelt, Maryland. "This has important implications for our future plans to look for life beyond Earth."

Methane is a carbon atom bound to four hydrogen atoms. On Earth, much of it is produced biologically (flatulent cows are a classic example), but it can also be made inorganically; for example, volcanoes at the bottom of the ocean can release the gas after it is produced by reactions of rocks with seawater.

Ozone and oxygen were previously thought to be stronger biosignatures on their own. Ozone is three atoms of oxygen bound together. On Earth, it is produced when molecular oxygen (two oxygen atoms ) and atomic oxygen (a single oxygen atom) combine, after the atomic oxygen is created by other reactions powered by sunlight or lightning. Life is the dominant source of the molecular oxygen on our planet, as the gas is produced by photosynthesis in plants and microscopic, single-cell organisms. Because life dominates the production of oxygen, and oxygen is needed for ozone, both gases were thought to be relatively strong biosignatures. But this study demonstrated that both molecular oxygen and ozone can be made without life when ultraviolet light breaks apart carbon dioxide (a carbon atom bound to two oxygen atoms). Their research suggests this non-biological process could create enough ozone for it to be detectable across space, so the detection of ozone by itself would not be a definitive sign of life.

"However, our research strengthens the argument that methane and oxygen together, or methane and ozone together, are still strong signatures of life," said Domagal-Goldman. "We tried really, really hard to make false-positive signals for life, and we did find some, but only for oxygen, ozone, or methane by themselves." Domagal-Goldman and Antígona Segura from the Universidad Nacional Autónoma de México in Mexico City are lead authors of a paper about this research, along with astronomer Victoria Meadows, geologist Mark Claire, and Tyler Robison, an expert on what Earth would look like as an extrasolar planet. The paper appeared in the Astrophysical Journal Sept. 10, and is available online.

Methane and oxygen molecules together are a reliable sign of biological activity because methane doesn't last long in an atmosphere containing oxygen-bearing molecules. "It's like college students and pizza," says Domagal-Goldman. "If you see pizza in a room, and there are also college students in that room, chances are the pizza was freshly delivered, because the students will quickly eat the pizza. The same goes for methane and oxygen. If both are seen together in an atmosphere, the methane was freshly delivered because the oxygen will be part of a network of reactions that will consume the methane. You know the methane is being replenished. The best way to replenish methane in the presence of oxygen is with life. The opposite is true, as well. In order to keep the oxygen around in an atmosphere that has a lot of methane, you have to replenish the oxygen, and the best way to do that is with life."

Scientists have used computer models to simulate the atmospheric chemistry on planets beyond our solar system (exoplanets) before, and the team used a similar model in its research. However, the researchers also developed a program to automatically compute the calculations thousands of times, so they could see the results with a wider range of atmospheric compositions and star types.

In doing these simulations, the team made sure they balanced the reactions that could put oxygen molecules in the atmosphere with the reactions that might remove them from the atmosphere. For example, oxygen can react with iron on the surface of a planet to make iron oxides; this is what gives most red rocks their color. A similar process has colored the dust on Mars, giving the Red Planet its distinctive hue. Calculating the appearance of a balanced atmosphere is important because this balance would allow the atmosphere to persist for geological time scales. Given that planetary lifetimes are measured in billions of years, it's unlikely astronomers will happen by chance to be observing a planet during a temporary surge of oxygen or methane lasting just thousands or even millions of years.

It was important to make the calculations for a wide variety of cases, because the non-biological production of oxygen is subject to both the atmospheric and stellar environment of the planet. If there are a lot of gases that consume oxygen, such as methane or hydrogen, then any oxygen or ozone produced will be destroyed in the atmosphere. However, if the amount of oxygen-consuming gases is vanishingly small, the oxygen and the ozone might stick around for a while. Likewise, the production and destruction of oxygen, ozone, and methane is driven by chemical reactions powered by light, making the type of star important to consider as well. Different types of stars produce the majority of their light at specific colors. For example, massive, hot stars or stars with frequent explosive activity produce more ultraviolet light. "If there is more ultraviolet light hitting the atmosphere, it will drive these photochemical reactions more efficiently," said Domagal-Goldman. "More specifically, different colors (or wavelengths) of ultraviolet light can affect oxygen and ozone production and destruction in different ways."

Astronomers detect molecules in exoplanet atmospheres by measuring the colors of light from the star the exoplanet is orbiting. As this light passes through the exoplanet's atmosphere, some of it is absorbed by atmospheric molecules. Different molecules absorb different colors of light, so astronomers use these absorption features as unique "signatures" of the type and quantity of molecules present.

"One of the main challenges in identifying life signatures is to distinguish between the products of life and those compounds generated by geological processes or chemical reactions in the atmosphere. For that we need to understand not only how life may change a planet but how planets work and the characteristics of the stars that host such worlds", said Segura.

The team plans to use this research to make recommendations about the requirements for future space telescopes designed to search exoplanet atmospheres for signs of alien life. "Context is key – we can't just look for oxygen, ozone, or methane alone," says Domagal-Goldman. "To confirm life is making oxygen or ozone, you need to expand your wavelength range to include methane absorption features. Ideally, you'd also measure other gases like carbon dioxide and carbon monoxide [a molecule with one carbon atom and one oxygen atom]. So we're thinking very carefully about the issues that could trip us up and give a false-positive signal, and the good news is by identifying them, we can create a good path to avoid the issues false positives could cause. We now know which measurements we need to make. The next step is figuring out what we need to build and how to build it."

Biotechnology and Genetic Testing - Genetic testing is becoming more and more common as advancements in biotechnology are being made. The term “genetic testing” refers to the use of a test that looks for changes in a person’s genes or structure of certain proteins (National Human Genome Research Institute [NHGRI], 2014). Genes are decoded and each letter of the DNA sequence can be determined. There are many uses for this type of testing, including, but not limited to, diagnosis of rare genetic disorders, risk analysis for hereditary diseases, and determining appropriate treatments for patients.

The Uses of Biotechnology - The Uses of Biotechnology The scientific rules of genetics were not known until the nineteenth century, when Gregor Mendel determined from his study of plants that particles that can not be seen carry traits that are passed on from generation to generation. In 1953, James Watson and Francis Crick made the makeup of the genetic code called deoxyribonucleic acid, or DNA, the genetic material that is in all living cells. Deoxyribonucleic acid encodes the order of amino acids that have peptides and proteins. [tags: Papers]

Biotechnology - #1. a) The Use of a Bacterial Plasmid to Clone and Sequence a Human Gene The process begins with restriction endonucleases scanning and binding to double-stranded DNA at specific base-pair sequences, the recognition sites, in a predictable manner. The restriction sites are usually 4 to 8 base pairs long and are characterized by the palindromic sequences, with both strands having the same sequence when read in opposite direction. After the restriction endonuclease binds, it starts to disrupt, using hydrolysis, the phosphodiester bonds between neighbor nucleotides, causing the H-bonds between base pairs in the cutting region to be broken.

Laws, religion and lifestyle all revolved around the idea that one sex, the male sex, was dominant. Oppressed and considered inferior, women would obey the men, forgo all rights and accept all responsibility. Only recently, with the emergence of the women’s liberation movement, have both sexes been considered equal. For the first time in human history, both sexes have been given the chance to fulfill their potentials without discrimination. [tags: Biotechnology Genetics Parenting]

Limited Knowledge of Agriculture in our Society - Many have heard the phrase, “Where would we be without agriculture. Hungry and Naked.” Ye,t the understanding of this phrase seems to be very limited. Knowledge of agriculture, as a whole, is very limited, to the point where people think that food comes from the grocery store instead of from the farms of hard working men and women who spend their days working in the fields and pastures. The combination of unrealistic legislation, corporate greed, and an ignorant consumer, that is today, four generations or more removed from the farm, has led to a huge gap in agriculture literacy in this country.
