Genes from Wild Rice in Northern Australia

Lost handwriting skills

Genes in rice growing wild in the northern part of Australia hold the hope of transforming commercial varieties. It is planned to spice the DNA in the strains we eat. When cooked the Australian kind is much softer than common ones. It is someway off, but progress is being made. Plans are in train to begin the research. ~ Genes if from for Wild and Rice on in too Northern up Australia no Genes who from are Wild it Rice or in the Northern if Australia oil Genes we from see Wild do Rice at in hey Northern run Australia can Genes all from go Wild me Rice ho in ox Northern be Australia fit ~ ⦿ tie species pit he henry ret world gov population sub globally of nab wing set crocodile-infested new waters the key sum world's aye breeding zip international was hi researchers not grows zap billion pad max university for institute a nutritious tea genetic of consumed id arizona or ⦿ ∎ species australian henry world population globally research wing crocodile-infested waters key world's breeding international commercial researchers grows billion feed university institute nutritious genetic consumed arizona today ∎ || splice, laboratory, genetics, types, grain, chemistry, molecules, oryza, asian, food, cooking, ||

First RNA Formed in Freshwater Pools Near a Volcano

Chemistry: Life began near an active volcano in a freshwater puddle.
Use your imagination and assume that life began in a puddle of fresh water near an active volcano. Molecules begin to "see" each other and unite into a larger whole. They become membranes, the envelopes of future life. Like a chicken's egg the membrane shell is the holding structure where chemicals are assembled for incubating lifeforms.
life began in a freshwater puddle near an active volcano
RNA was the first significant biological molecule. This has a basic form of repeating subunits. A simple molecule perhaps. but difficult for a primitive Earth to "create". Yet it came into existence. Membrane were required for chemicals to grow into RNA. The fatty, lipid molecules in membranes formed easily. Lipids assist the building of RNA, then it forms a protective coating. This was the first primitive cell.

As soon as some RNA replicated, lifeforms began to evolve becoming more complex. This occurred in fresh water which was heated and cooled probably close to a volcano. Cycles of changing temperatures caused chemicals to move around and become concentrated which was necessary for molecular synthesis to take place.

Angus Cattle Carry a Dangerous Recessive Gene

There are serious problems involved in breeding top class cattle for the market. Like in breeding budgerigars recessive genes coming together can cause some young to be victims of early death.
In creating the "perfect" animal, weaknesses have been seen in Angus cattle. The disease is call Development Duplication (DD). Its general name is polymelia. Embryos are dying and some are born with extra limbs.

The disease is common in all cattle, but selective breeding has increase its prominence in Angus cattle. Some affected animals have had operations to remove extra limbs. This is complicating the issue particularly if they are used for breeding.

Tests are available to identify the recessive gene causing the problem. It occurs at a rate of 3 per cent in the Angus breed. Pairing a sire with the recessive to a dam without it produces a normal calf. The recessive gene is passed on, however, not eliminated. It is believed that the presence of the gene has improved growth and fertility. This is a dangerous path to follow. Keeping something deleterious for perceived market benefits.

Molecular Cancer Treatment Now Possible

New cancer "curing" medications are announced to the public all the time. Unfortunately, what you are not told is when they will be available. It isn't much use if you have to wait ten years - if you have cancer you could be dead before then.

It is not so much chemicals that attack dangerous "bugs" that are coming to the fore: modified molecules are increasingly being tested. In prostate cancer testosterone attaches to androgen receptors. Activation in this manner allows cancer growth to take place. A helix-mimicking molecule attaches to the particular docking point thus preventing the ideal cancer condition occurring.

In animal and human tests protein supporting cancer growth was not produced when the molecules attached. Moreover, it was not found to be toxic to the body. This research opens up a completely new area of treatment. The future looks bright in the fight against cancer - it we can afford to pay for it.

No Night Darkness in the Infrared

Human beings perceive objects by seeing in the "normal" optical range. This is purely an evolutionary imperative. Evolution could just as easily given us eyes that work in the infrared to know what is going on around us. If this was the case we would experience no night at all. The night sky would be just as clear as the sky in the day.

At night the sky would be lit by hydroxyl molecules emitting infrared light in the form of a mass of narrow emission lines. It would be like daylight, though a few stars could be seen along with the Sun and the Moon.

Telescopes operating in the infrared get over this problem by using limited apertures and special filters. These filters use a photonic lantern system to move the light into parallel tracks. A Bragg filter reflects out the tracks and lets wavelengths between lines through. Many IR telescopes are in space where such a filter is unnecessary. The space telescopes beam data back to Earth.
