The Race to Understanding and Manipulating DNA :: Exploratory Essays Research Papers

Mid 1953. Three labs, two in England and one in California, hustled to find the structure of deoxyribose nucleic corrosive. At Cal Tech in Pasadena, California, Linus Pauling had as of late found the alpha-helix. Presently he was directing his concentration toward DNA. At King's College in the University of London, Maurice Wilkins and Rosalind Franklin, in spite of the fact that hampered by their powerlessness to coexist with each other, had taken real pictures of DNA utilizing x-beams and were hot on the path. The most improbable pair in the race, a 24-year-old American scholar and a 36-year-early English physicist, were likewise near distinguishing the subtle particle, in spite of the fact that they were illegal from legitimately chipping away at it. Thus the race increased for the mystery of life itself. Prepare, Get Set... Mendel and Pea Plants The occasions paving the way to this race really started with an Austrian priest named Johann Gregor Mendel. Despite the fact that in all actuality Mendel needed to be a secondary teacher, he bombed the required assessment multiple times and chose to turn into a priest to seek after his examinations in the tranquility of a cloister (Asimov, Genes 11). Inspired by the legacy of attributes, he started working with pea plants in 1857. He crossed genuine reared plants and afterward their posterity and recorded the outcomes. From these outcomes he set up general principles or laws for legacy. He labored for a long time and with more than ten thousand unique plants (Arnold 20). Searching for a patron for his work, Mendel sent his paper to noted botanist Wilhelm von Nageli. Nageli sent it back after scarcely looking at it (Nageli kicked the bucket in 1891 and would be recalled, not for his own immense logical work, however for his inability to focus on Mendel) (Asimov, Genes 19-20). Mendel at last published his outcomes in the magazine of the National History Society of Brunn in 1866 (Arnold 7). Different botanists gave practically no consideration to his work, and his thoughts regarding legacy got lost for thirty-four years. Mendel turned into the abbot of his religious community in 1868 and was excessively occupied and disheartened to proceed with his investigations. He kicked the bucket in 1884, never realizing that he would be touted as the father of present day hereditary qualities. The Early Work on DNA In 1869, soon after Mendel had stopped working with plants, a 25-year-old Swiss scientific expert, Johann Friedrich Miescher, found a substance called nuclein inside cells. This substance was later seen as joined to a protein which was named histone from the Greek word signifying cell.

The Benefits of Having Sex More Often

The Benefits of Having Sex More Often Relationships Spouses & Partners Print The Benefits of Having Sex More Often Emotional, Physical, and Relationship Benefits of Frequent Sex By Sheri Stritof Sheri Stritof has written about marriage and relationships for 20 years.

Learn about our editorial policy Sheri Stritof Medically reviewed by Medically reviewed by Carly Snyder, MD on November 20, 2019 facebook twitter linkedin Carly Snyder, MD is a reproductive and perinatal psychiatrist who combines traditional psychiatry with integrative medicine-based treatments.   Learn about our Medical Review Board Carly Snyder, MD on November 20, 2019 More in Relationships Spouses & Partners Marital Problems LGBTQ Violence and Abuse In This Article Table of Contents Expand Ideal Frequency Psychological Benefits Physical Benefits Relationship Benefits Challenges Tips View All Back To Top There are many reasons to have sex more often, at least when it comes to quality sex in a supportive relationship. More frequent sexual activity is linked to physical benefits, such as lower blood pressure, emotional perks, such as reduced stress, and relationship benefits, such as greater intimacy and a lower divorce rate.?? While there is not a magic number when it comes to the ideal frequency of sex, the results of a few studies can suggest a ballpark. Illustration by JR Bee, Verywell   Ideal Frequency As far as the ideal frequency, a 2015 study found that general well-being is associated with sexual frequency, but only up to a certain point.?? Relationship satisfaction improved progressively from having no sex up to having sex once a week but did not improve further (and actually decreased somewhat) beyond this point. This goal number is fairly consistent with the current average, but should be of concern with our increasingly busy lives. Looking at the frequency of sex in the 2010s, adults are now having sex nine times per year less than in the late 1990s.?? What Is the Average? Average adult: 54 times/year (about 1/week)Adults in their 20s: Around 80 times/yearAdults in their 60s: 20 times/yearAverages based on a 2017 study published in the Archives of Sexual Behavior. Even though the frequency often decreases with age, sexual activity in older adults remains very important to many people. Those who are married people tend to have sex more often than those who are not.?? Psychological Benefits There are many emotional and psychological benefits from making love that is strongly linked with overall quality of life. Some of these include: Happiness According to a 2015 study conducted in China, more sex and better quality sex increases happiness (though unwanted sex lowers happiness).?? Stress Relief That many people deal with chronic stress is a given and has been cited as a reason why adults are having sex less often. This may be a double whammy, as sex may be considered a stress management technique. Our bodies secrete cortisol and adrenaline (epinephrine) as part of the stress response. These hormones (the fight-or-flight response), can lead to fatigue, high blood pressure, and much more. Sex can reduce the level of these hormones, with effects that can last well into the next day.?? Improved Mood There are a number of chemicals our bodies release during sex that can affect how we feel. During sex, our brains release endorphinsâ€"feel good chemicals that can reduce irritability and feelings of depression. Another hormone, oxytocin (the hug drug), is released with nipple stimulation and other sexual activity.?? Similar to the effect it has on nursing mothers (oxytocin is responsible for the let down reflex in breastfeeding), oxytocin can create a sense of calmness and contentedness. Finally, orgasm leads to the release of yet another hormone, prolactin, that can aid in sleep.?? Improved Self-Image Sex can boost self-esteem and lower feelings of insecurity, leading to a more positive attitude. Physical Benefits Its fairly intuitive that sex would improve emotional health, but there are a number of physical benefits as well. Some of these include: Improved Physical Fitness Sex is a form of physical activity, and there are a number of studies linking exercise with better health. According to a statement from the American Heart Association, sexual activity is equivalent to moderate physical activities such as walking briskly or climbing two flights of stairs.?? The movements associated with sex can tighten and tone abdominal and pelvic muscles. For women, this improved muscle tone translates to better bladder control. The 200 calories burned in 30 minutes of sex,?? combined with the reduction in food cravings associated with the chemicals released during sex, are beneficial as well. Better Immune Function Being more sexually active also has positive effects on immune function.?? This translates to a lower likelihood of getting a cold or the flu. Reduced Pain The endorphins mentioned above do more than lead to a sense of well-being and calm, but appear to reduce pain (such as migraines and back pain) as well. Cardiac Effects Sexual activity (but not masturbation) has been linked with lower systolic blood pressure.?? Elevated blood pressure, in turn, is associated with an increased risk of heart disease, stroke, and more. Its thought that sexual activity helps dilate blood vessels, increasing the delivery of oxygen and nutrients to the cells of the body while reducing blood pressure. Its important to note that having sex can also promote a heart attack in those at risk, but having sex more often may help reduce this concern. While sex can precipitate a heart attack, and anyone at risk should talk to their doctor before having sex, a 2011 study published in JAMA, found that this risk is diminished in people who have high levels of regular sexual activity. In other words, and similar to other forms of physical activity such as running, infrequent activity could put a strain on the blood flow to the arteries supplying the heart, but regular activity may be protective.?? Brain Effects In the past, studies in rats found that more frequent intercourse was correlated both with better cognitive function and the growth of new brain cells. Researchers are now learning that the same may be true in humans. A 2018 study looking at over 6,000 adults found that having sex more often was associated with better memory performance in adults ages 50 and older.?? Sexual Effects Being more sexually active actually boosts libido and increases vaginal lubrication in women. Making love is more often associated with lighter menstrual periods and less bothersome period cramps. For men, while it was once thought that sex caused an increase in prostate cancer, a 2016 study found that men who had more ejaculations (21 or more per month) were less likely to develop the disease than men who had fewer (seven ejaculations or less per month). Since prostate cancer is the second leading cause of cancer-related deaths in men,?? this is worth noting. Other Physical Effects A number of other physical effects have been associated with more sexual activity, such as an improved sense of smell, healthier teeth, improved digestion, and that healthy-skin glow thats related to an increase in the release of DHEA by the body. Unsafe sex could tip the scale of benefits and risks in the opposite direction. Make sure you are familiar with safe sex practices. Relationship Benefits Having sex often can benefit you and your partner individually, but it can also help your relationship in a number of ways. Having regular sex in a monogamous relationship can increase your level of commitment and help you connect emotionally. Couples are more likely to stay together when they can express their love in this way, and the divorce rate is significantly higher for couples who dont. The relational benefits of sex are assisted by the chemicals our bodies make: The release of oxytocin, in addition to being calming, can contribute to bonding and greater emotional intimacy.?? Challenges We are wired from birth to crave the intimacy of sex, and lacking sex is one of the things that can lead people in a relationship to grow distant and, perhaps, look elsewhere. Its important to note, however, that an active sex life is sometimes difficult or impossible due to physical or psychological conditions. Couples can maintain a strong, healthy relationship despite this, and looking at non-sexual ways to improve intimacy is invaluable even for those who cant have sex on a regular basis. Working with a licensed couples therapist can help as well. Jumpstarting Your Sex Life The frequency of sex can, and often does, change over time, but that doesnt mean that its a progressive downhill slide. If youre wondering if sex can ever be as good as when you were first madly in love, the answer is yes. It can even be better when you add in what you didnt have before: a stable loving relationship thats grown mature and intimate. That said, it can take work. There are a number of ways to spice up your sex life, but looking at the non-sexual parts of your relationship is just as important. As many say, the biggest sex organ is between the ears. Increasing the frequency of sex without talking and connecting emotionally isnt likely to create lasting improvement. Stress management is also important. In her book, The Sex-Starved Marriage: Boosting Your Marriage Libido, a Couples Guide, therapist Michele Weiner-Davis  suggests taking a just do it approach: At first, many were understandably cautious about my Nike-style approach to their sex life; the Just Do It advice ran counter to everything they had believed about how sexual desire unfolds...I could often see the relief on peoples faces when they learned that their lack of out-of-the-blue sexual urges didnt necessarily signify a problem. It didnt mean there was something wrong with them or that something was missing from their marriages. It just meant that they experienced desire differently. If you always wait for your level of desire to match that of your partner, you may be waiting a long time. Getting in the Mood for Sex A Word From Verywell There are obviously many benefits to having sex more often (or a minimum of once a week) in a loving and supportive relationship. That said, all is not lost in your relationship if you are unable to have sex this frequently or at all. Your love can grow just as strong. If you are able to have sex but not enough, ask yourself why. Sometimes seeing a sex therapist may be the best way to work through any issues you are having. Keep in mind that it could make a difference not just for your relationship, but for your own physical and emotional health as well. The 6 Best Online Marriage Counseling Programs
