A pill could cure jet lag

The symptoms of a jet lag can be quite varied depending on the amount of time zone alteration. These conditions may last several days. Researchers at the Sleep Research Centre in the University of Surrey ,U.K., discovered that disrupted sleep cycles associated with shift work and jet lag have negative effects on the human health including diabetes and obesity, especially those who travel often due to work .These serious diseases become fatal when the body’s clock is out of sync for extended periods of time. One previous study discovered that jet lag damages the body because significant genes are not switched on. Additionally, the risk of heart attacks and strokes increases by more than 40%.

 

Fortunately, Dr. David Bechtold could possibly lead to an invention of a pill that inhibits the enzyme, CK1epsilon in humans.  Lacking CK1epsilon could adjust to a new light-dark cycle much faster than normal making one cope better when lights are turned on and off at times contrast to their natural day-night pattern. Thus, a pill that inhibits the enzyme could help the body’s clock adapt to sudden changes, assisting people to recover from a jet lag rapidly. These drugs will be available in approximately five years.

Sharing a bed is always risky for infants

Sharing beds with infants is one of the leading causes of sudden infant death syndrome (SIDS). SIDS is an infant unexpected death, which cannot be predicted by scientific history. The syndrome is known to have a higher risk during an infant’s sleep. SIDS was the third primary cause of infant mortality in the United States in 2011. Even though the cause of SIDS is unidentified, some factors such as bottle feeding and the mother’s intake of illegal drugs and alcohol have been known to increase the risk of the fatal syndrome. When sharing a bed with parents, the risk of SIDS increases by five fold, especially babies younger than three months.

   Sleeping with parents for infants is a significant risk source during the first 15 weeks even without any other danger factors such as being exposed to second hand smoking. But this risk is increased to a great extent if either parent is a smoker. Other possible suggested risks may occur when the adult accidentally roll over onto a sleeping infant and the parents’ body heat may not be the suitable temperature for the baby. On the other hand, there is a benefit of an infant sleeping with their parents. It promotes breathing control and enhances mutual awareness between parents and infants. Nonetheless, when infants are put to sleep in the same bed as their parents, there is a great amount of risk and there should be a high level of precaution. Parents or parents to be should possess a sufficient amount of knowledge regarding this syndrome.

World’s Scarcity: Social Aspects of Human Cloning and A Need For a “Financially Motivated Animal Cloning”

Video: First Human Embryo Cloned

Triggered by the Scottish scientists’ successful cloning of a female sheep called Dolly – the first mammal to be cloned – human cloning has become a contemporary phenomenon drawing comparisons to natural creation of humans. Immediately, debates on the ethical issues about cloning and numerous researches on further social implications associated with human cloning rose. Nevertheless, many scientists and technologists advocated the “immorality” of human cloning and, therefore, research funding in the need for human cloning have been denied and blocked in many countries. Numerous misconceptions about cloning rose by the science fiction: cloned humans will exactly be the same as their genetic donors. This is not true, since, although cloned humans are born with the same genes inherited from their partners, their environments in living, their history and experiences will determine what they become in the future.

There are both advantages and disadvantages to the practice of cloning. Jessica  in “The Advantages and Disadvantages in Cloning” argues that not only does cloning give benefits to modern medicine, but it also helps infertile couples and reverses the aging process of individuals. Moreover, cloning permits the study of genetic diseases and indeed genetic development more generally. Specifically, cloning could help “carriers” of X-linked and autosomal recessive disorders to have their own genetic children without risk of passing on the disease. On the other hand, human cloning is also considered as a threat to genetic diversity and evolution. Humans already destroyed the natural evolution process by inventing all kinds of medicine; people who were supposed to die by nature are still living because they can extend their life by using unnatural chemicals in which most of medicines are made of.

 

While most of research papers discuss the ethics and consequences of human cloning, these paper analyses how cloning can be “financially motivated” for profit. There are two types of human cloning – Therapeutic and Reproductive. Therapeutic cloning involves the production of human tissues, thus organs, while reproductive cloning produces human beings. This paper specifically focuses on reproductive cloning – cloning of humans – and how human cloning is practiced as an investment on income and technology. Two steps are discussed: cloning human beings with improved ability and using the cloned individuals for purely financial reasons.

 

There is an economic incentive to clone for financial purposes. For instance, it is profitable when economically valuable animals that may be worth hundreds of thousands of dollars are cloned. Moreover, if top performers in the labour market have valuable genes, then cloning them will generate a lot of financial value. This continuing process of cloning individuals with intelligent genes will lead to improvements in technology and, later on, living standards, as well.
