Honey bees are disappearing all over the world.  The loss is increasing: 15 percent 10 years ago reaching as high as 40 per cent today.  Oddly, production has not fallen  mainly because more apiaries are being established to counter losses.  This is despite reduced habitat due to building, pesticides, parasites, pests and pathogens.
Australian Varroa Resistant Bees
The main killer identified is the Varroa mite which latches on to bees during the formation process.  The mite is in most countries except Australia.  The "Australians" are being bred for introduction to other places.  Unfortunately, they do not do well in cooler climates.

Pesticides are suspected of causing bee decline.  It is recommended that pest chemicals only be sprayed at night when apis return to hives.  If one gets poisoned thousands can die when it goes back to the hive - if it gets that far.  Anyway, they forage in the same area so many succumb.

Bayer Chemistry to Develop New Herbicides

Chemistry: Weeds are becoming resistant to selective herbicides.
Herbicides have officially been used since 1890, though common salt could have used to kill weeds for possibly a thousand years before. The first selective herbicide was identified in 1940. It later became 2,4-D compound and was released in 1946.  Seventy years later we face the problem of weed resistance to selective chemicals. Western Australia can no longer get significant kill of weeds growing around crops. It is costing farmers a fortune.
Ryegrass weed growing in crops
Project Kangaroo has been initiated. It is managed by Australia’s Grains Research and Development Corporation (GRDC) and receives assistance from Bayer of Germany. Money from growers is funding it: they are paying $45 million in levies. The Federal Government is promising money. Knowing how government has behaved recently the project might get a dollar!

Wild radish and ryegrass are the main culprits affecting crops. Glyphosphate was used widely to control these weeds. They are not very effective these days. Chemical companies need to take a new tack and work at the molecular, even atomic level, to find ways of killing selective weeds. Nature though is good at overcoming new things in the environment. It is only a matter of time before evolution beats "unique" obstacles set up by Man.

Efficient Solar Panel Paint Developed

There is about to be a revolution and it is not wearable technology. A spray on paint to quickly make solar panels has been perfected. The paint's main ingredient is perovskite - a calcium titanium oxide mineral. Furthermore, it costs very little.

Soon cheaper solar panels will be flooding out of factory production lines. They will be used everywhere - even on wearables! Perovskite is twice as effective as current spray-on solar collectors.

The environment will be "covered all over" with this new effective paint. Every surface facing upward whether on something mobile or static will have this coating.

Dramatic change will seen on buildings. Indeed, it will be available in many colors and will become an important part of the designed environment. Battery powered cars will have the paint completely covering the vehicle. It will become as common as ordinary paint is today.

Money Wasted On New GM Grape Vine

Although GM foods have spread quietly throughout the world slipping under lax labelling systems, people are still suspicious of them. Because of the strict ban on their distribution in Europe if something disastrous happen to those who unknowingly consume them, Europeans will have the last laugh.

It seems scientists are obsessed with DNA modification of anything they can get their hands on. Wine has been made for centuries from grapes that are perfect for the job. Just why one would want to mess around with the DNA of the humble grape vine is a mystery. For ten years scientists in Adelaide have been trying to modify grapes to make them resistant to mildew. This disease can easily by prevented by spraying with fungicide.

There has been limited success in the laboratory. Tests in the field will follow. There is a problem, however, a Significant proportion of Australian wine is sold in Europe, where as mentioned above there is a ban on the sale of genetically modified food. What a waste of time and money having people and resources tied up in something that is basically unwanted.
