KAI2 Improves Growth as Well as Germination After Fire

KAI2 improves plant growth after a fire germination
Why do plant seeds in Australia start germinating after a fire? It is because of Karrikin Insensitive2 (KAI2) a protein which has been present in plants for millions of years. KAI2 has been important for all plants for 400 million years.

When the KAI2 protein was removed from a higher, more recent plant, Arabidopsis thaliana, its leaves malformed. Yet splicing the KAI2 back by taking it from the ancient Selaginella resulted in improved A. thaliana growth, but it could no longer detect the presence of smoke the normal function of KAI2.

This finding shows the more general function of KAI2. It not only identifies karrikins in smoke, it is important for plant growth. "Sensing" is the main purpose of KAI2. Apparently it can be tuned to detect different things. This could help farmers control seed germination times.

Wheat is notorious for germinating in the grain during heavy rain periods. Being able to spray a chemical that stops this would save millions of dollars and improve crop yields. Furthermore, spraying to stop weeds from sprouting would be the supreme herbicide.

We are Heading Toward a Drugged-Up World

A new survey has found that school children under 17 years who smoke cannabis are less likely to complete their high school education. This is not surprising as cannabis "kills" the rational part of the brain and makes users impulsive, unable to control their actions.

Addicts are driven through a path in life from one pleasurable thing to another. They avoid all uncomfortable situations immediately, seeking the nearest pleasure at hand. This is why they end up breaking the law and becoming incarcerated.

Suicide is high amongst cannabis users because good experiences are not always for the taking. When one works at a job it is not pleasant, nor is it truly sought after. However, unless the discomfort is suffered there will be no pleasure from spending the income.

Legalization for medical use is another step toward general access. Many young people are already unfit for the workforce because schools do not teach work related skills. Education needs radical reform. We need to turn the clock back. Get rid of the choice subjects and make all students do fundamental, core subject like in the old days. Rote is not a dirty word. Every older person knows the twelve times table by heart even in old age. Having all student repeat things out loud, together is a good thing. How are they to discover the answers on their own?

Like in ancient days in China when people spent their days slothfully wasting time sitting under a tree waiting for ripe fruit to fall, we are heading toward a world where everyone expects welfare and someone else will do the work. Drug taking is bringing this closer.

Energy Use Due to Mobile Phones Is Unstainable

There is an energy crisis slowly creeping up on us. We go about our daily business enjoying the benefits of computer advances while not realizing that massive amounts of energy are being consumed.

Mobile phones are designed with very little hard storage. Reliance on cloud services is increasing at a rapid pace. Many developing countries do not enjoy continuous energy supplies. When the electricity goes off so does cloud storage. In advanced countries aluminium producers were blamed for eating up too much power, now everyone is responsible.

A new study, The Power of Wireless Cloud, clearly shows that the continuing use of electricity is not sustainable. Energy use by cloud services will be equivalent to 4.9 million cars over the period 2012-2015. This is known by comparing energy from petrol to power station input.

It is not just the cloud. Wi-Fi will use more power than anything else. Computing networks are not "clean". Many do not consider that most electricity is still being produced with dirty energy inputs. Even nuclear is dirty - it contaminates.

Cannabis Can Cause Bronchitis and Cancer

If you thought smoking cannabis had no health dangers and was safer than smoking cigarettes, you would be wrong. The smoke from both have similar harmful gaseous and particulate chemicals.

Smoking cannabis is more dangerous than smoking cigarettes. This is due to the way people behave when inhaling. They try to keep the smoke in the lungs as long as possible in order to get the greatest euphoric effect.

Indeed, inhaling smoke from cannabis causes changes in the lungs consistent with bronchitis. Cellular dysplasia indicates malignancy could be the end result. Users believe lung cancer is solely due to smoking tobacco, but a cough and morning sputum production show cannabis use can lead to cancer.

Cannabis smoking is addictive and damages your health. Combining this pastime with cigarette smoking is doubly dangerous.
