The Lucifer Principle is a 1995 book by American author Howard Bloom, in which he argues that social groups, not individuals, are the primary "unit of selection" on genes and human psychological development. He states that both competition between groups and competition between individuals shape the evolution of the ge...

The Crich β-mannosylation in organic chemistry is a synthetic strategy which is used in carbohydrate synthesis to generate a 1,2-cis-glycosidic bond. This type of linkate is generally very difficult to make, and specific methods like the Crich β-mannosylation are used to overcome these issues. The technique takes its n...

They receive information from ethical experts to better predict and understand future and current potential gene editing issues. The World Health Organization has launched a global registry to track research on human genome editing, after a cal...

Division of Bioethics at New York University suggests that establishing an international group to set guidelines for the topic would greatly benefit global discussion and proposes instating "religious and ethics and legal leaders" to impose well-informed regulations. In many countries, editing embryos and germline modi...

Jackie Leach Scully, professor of social and bioethics at Newcastle University, acknowledges that the prospect of designer babies could leave those living with diseases and unable to afford the technology feeling marginalized and without medical support. However, Professor Leach Scully also suggests...

David Pearce argues that "the question [of designer babies] comes down to an analysis of risk-reward ratios - and our basic ethical values, themselves shaped by our evolutionary past." According to Pearce,"it's worth recalling that each act of old-fashioned sexual reproduction is itself an untested genetic experiment",...

technology gets mature enough for real world use, where all of the potential effects are known on a case-by-case basis to prevent undesired effects on the subject or patient being operated on. Social aspects also raise concern, as highlighted by Josephine Quintavelle, director of Comment on Reproductive Ethics at Queen...

from God, and Catholics believe that people are created to be perfect in God's eyes. Thus, altering the genetic makeup of an infant is unnatural. In 1984, Pope John Paul II addressed that genetic manipulation in aiming to heal diseases is acceptable in the Church. He stated that it "will be considered in principle as d...

Other arguments include the possibility of introducing unforeseen mutations and genetic deficiencies, which would be counter to the princ...

Biodilution, sometimes referred to as bloom dilution, is the decrease in concentration of an element or pollutant with an increase in trophic level. This effect is primarily observed during algal blooms whereby an increase in algal biomass reduces the concentration of pollutants in organisms higher up in the food chain...

of cadmium, lead, and nickel with an increase in trophic level Cadmium and lead are both non-essential metals that will compete for calcium within an organism, which is detrimental for organism growth. Most studies measure bioaccumulation and biodilution using the δ15N isotope of nitrogen. The δ15N isotopic signature i...

The osmotic stress technique is a method for measuring the effect of water on biological molecules, particularly enzymes. Just as the properties of molecules can depend on the presence of salts, pH, and temperature, they can depend significantly on the amount of water present. In the osmotic stress technique, flexible ...

A thermodynamic instrument is any device for the measurement of thermodynamic systems. In order for a thermodynamic parameter or physical quantity to be truly defined, a technique for its measurement must be specified. For example, the ultimate definition of temperature is "what a thermometer reads". The question follo...

equilibrium with each other. This principle, as noted by James Maxwell in 1872, asserts that it is possible to measure temperature. An idealized thermometer is a sample of an ideal gas at constant pressure. From the ideal gas law, the volume of such a sample can be used as an indicator of temperature; in this manner it...

quantity of water at its triple point forms an effective temperature reservoir. == Theory == Let's assume that we understand mechanics well enough to understand and measure volume, area, mass, and force. These may be combined to understand the concept of pressure, which is force per unit area and density, which is mass...
