Australian Bees Use Their Heads

Bees don't just take pollen: they physically make flowers release the pollen. The, Australian blue-banded bee, Amegilla murrayensis, and the North American eastern bumble bee, Bombus, impatiens, were compared.

Slow motion filming enabled observation of bee behavior. North American bees grabbed the flower anther with their mandibles (hands) then tensed their wing muscles and began to "vibrate' the pollen free. This proces was carried out once per flower

Blue-banded bees did not use their mandibles at all. They used their heads, literally. They headbutted the flowers with their heads repeatedly at a very high frequency. The frequency was higher than the North American bee so the blue bee visited more flowers. However, the Australian bee came back several times to the same flower to give it another go.

Overall, the blue-banded bee is a more efficient pollinator. If used by growers it could potentially produce more fruit and vegetable.

Wasps Favor Large Size for Sex

Size matters when it comes to sex. When in the orchid world it does anyway! The plants rely on wasps for fertilization. Apparently, male wasps are attracted to the largest orchids. Shape of plants also has a role.

Male wasps visit large orchids to pollinate them

Orchids are a replica of female wasps, in shape and scent. Two orchids who had two kinds of wasps enamored with them were observed. The wasps did visited both types of plants but they spent more time "copulating' with their favored orchid.

Scent is offered to male wasps on little black beads. This only attracts males to the flowers. Once there, shape and size of blooms affects whether wasps stay or go. Orchids also benefits from this because plants with larger flowers are fertilized and they produce the next generation of orchids.

Solution to Bee Die-Off?

It is not widely known just how important bees are to maintain our food output, let alone to increase it as demand strengthens. There are so many mysteries to why bees are dying off across the world. Many theories are put forward. Unfortunately, there are few answers to the problem.

We need to look after the human friendly insect. It could eventually be found that bees are being killed off by chemicals. However, like other animals bees need chemicals to treat illnesses. When they become infected they change their foraging habits seeking pollen from plants that store certain chemicals. The solution to bee die-off could lie in studying this phenomenon.

Plants synthesize chemicals that attract select species of pollinators. Other substance also deter potential attackers. Herbivores have been real pests to plants for millions of years. Eating the leaves can kill plants. Insects have evolved to go where plant toxins drive herbivores away.

All nectar is not the same. If toxins can drive away herbivores, beneficial elements could attract bees as and when the insects needs it. A study infected bees with a gut parasite. One group was fed on sucrose while another group was given secondary compounds from plant nectar. The amount of parasite infestation was greatly reduced in the group which consumed secondary compounds.

Psychedelics Should Be Used to Treat Depression

Perhaps the drive to ban drugs is misplaced. The war is being lost anyway. Since the 1960s research on psychedelic drugs has been frowned upon. However, recent findings show benefits from imbibing these chemicals which come mainly from mushrooms.

Psychedelics alter perception so that an individuals sees strange things that are not there. A side benefit is an improvement in mood. Anxiety and depression tend to disappear. Research in the US and Europe is really taking off. Oddly, although the drugs have been banned they are not addictive.

Australia is not following the lead. It is still stuck in the past with talk about psychedelics being hushed up. A further problem is that chemicals derived from mushrooms and cacti are not patentable. There is no big money in it.

The harm done by regular intake of psychedelics is near zero. Quite different from the common belief. Many of the elderly suffer from psychological problems. If these can be solved by putting the aged into a better state of mind a lot of good will be done.

Black Tulips and Blue Roses - All Is Possible

Black Tulips and Blue Roses - All Is Possible

The black tulip will soon be a reality. Development of a blue rose has nearly be achieved. A new rose that is "nearly" blue is soon to be released onto the Japanese market. The asking price - a quite low $30 each.

There is no blue pigment in a rose, so it is impossible for a natural rose to display this color. The tone has to be put into the plant. It has been done by genetically splicing color into the rose from Petunias. This flower has a blue pigment called Delphinidin. The combined project by both Japanese and Australians has taken twenty years to create the "blue" rose.

American nurseryman Samuel Parsons said as long ago as the 19th century that one day scientific advances would lead to the cultivation of a blue rose. Attempts have been made in the 20th century. A blue-grey rose was bred, but it flowered only once.

For many years roses dyed blue have sold well in England. Unfortunately, horticultural advisor to the Royal Horticultural society, Helen Bostock, believes a blue rose will not be accepted. She is probably wrong about this. People are fascinated by anything new. It is probably "sour grapes" that the blue rose was not created in England. Another English rose grower Bernard Mehring is a bit miffed as well. He says he wouldn't grow it in his garden. He wants British controls to keep the plant out of the country. This is a sad situation that wreaks of elitism. China, however, will want the new rose because there a blue flower signifies hope toward reaching an unattainable love.
