Roundup Ready Corn 2

Roundup is the brand name of a herbicide produced by Monsanto that contains the active ingredient glyphosate. Glyphosate is the most used herbicide in the USA, and Roundup has been the number one selling herbicide worldwide since at least 1980. Several weed species, known as superweeds, have developed Roundup resistance largely because of repeated exposure.

Monsanto also produces seeds which grow into plants genetically engineered to be tolerant to glyphosate, which are known as Roundup Ready crops. The genes contained in these seeds are patented. Soy was the first Roundup Ready crop, and was produced at Monsanto’s Agracetus Campus located in Middleton, Wisconsin in 1996. As of 2005, 87% of U.S. soybean fields were planted with glyphosate resistant varieties. The Roundup Ready line of seeds has grown to include corn, canola, cotton, and other crops. The latest iteration is Roundup Ready Corn 2.

Golden Rice 2

golden rice 2

Golden rice is a variety of  rice produced through genetic engineering to biosynthesize beta-carotene, a precursor of pro-vitamin A in the edible parts of rice. The scientific details of the rice were first published in Science in 2000.  Golden rice was developed as a fortified food to be used in areas where there is a shortage of dietary vitamin A. In 2005 Syngenta, a biotechnology company announced a new variety called Golden Rice 2 which produces up to 23 times more beta-carotene than the original variety.

Neither variety is currently available for human consumption. Although golden rice was developed as a humanitarian tool, it has met with significant opposition from environmental and anti-globalization activists.

Intermittent Explosive Disorder

Intermittent explosive disorder (IED) is a behavioral disorder characterized by extreme expressions of anger, often to the point of uncontrollable rage, that are disproportionate to the situation at hand. It is currently categorized in the Diagnostic and Statistical Manual of Mental Disorders as an impulse control disorder. Impulsive aggression is unpremeditated, and is defined by a disproportionate reaction to any provocation, real or perceived.

Individuals diagnosed with IED report their outbursts were brief (lasting less than an hour), with a variety of bodily symptoms (sweating, chest tightness, twitching, palpitations). Violent acts were frequently accompanied by a sensation of relief, and in some cases, pleasure, but accompanied by remorse after the fact.

Solar Puffing

Solar puffing

Solar puffing refers to the act of using a magnifying lens to heat cannabis for consumption. Utilization of this method avoids residues left by butane or other propellants used in lighters and matches, and a greater amount of THC is extracted due to a lower heating temperature as opposed to that of combustion. This method is similar to that of vaporization.

Sun Tea

sun tea

Unsweetened iced tea is sometimes made by a particularly long steeping of tea leaves at lower temperature (one hour in the sun versus 5 minutes at 80-100°C). Some people call this ‘sun tea.’

In addition, sometimes it is also left to stand overnight in the refrigerator. Sun tea is easy to make, but can be toxic if not made carefully. If there are ropy-looking strands in the tea, or any other unusual-looking particles, or if the tea looks thick or syrupy chances are it has become a bacterial hotbed. A very clean container (including the spigot if there is one) and a caffeinated tea will deter bacterial growth for a few hours. Sun tea should be discarded after that period.
