Bees Can ‘Turn Back Time,’ Reverse Brain Aging

ScienceDaily (July 3, 2012) — Scientists at Arizona State University have discovered that older honey bees effectively reverse brain aging when they take on nest responsibilities typically handled by much younger bees. While current research on human age-related dementia focuses on potential new drug treatments, researchers say these findings suggest that social interventions may be used to slow or treat age-related dementia.

Old bees collect nectar and pollen. Most bees start doing this job when they are 3-4 weeks old, and after that they age very quickly. Their bodies and wings become worn and they loose the ability to learn new things. Most food collector bees die after about 10 days. (Credit: Christofer Bang)
 

In a study published in the scientific journal Experimental Gerontology, a team of scientists from ASU and the Norwegian University of Life Sciences, led by Gro Amdam, an associate professor in ASU’s School of Life Sciences, presented findings that show that tricking older, foraging bees into doing social tasks inside the nest causes changes in the molecular structure of their brains.

“We knew from previous research that when bees stay in the nest and take care of larvae — the bee babies — they remain mentally competent for as long as we observe them,” said Amdam. “However, after a period of nursing, bees fly out gathering food and begin aging very quickly. After just two weeks, foraging bees have worn wings, hairless bodies, and more importantly, lose brain function — basically measured as the ability to learn new things. We wanted to find out if there was plasticity in this aging pattern so we asked the question, ‘What would happen if we asked the foraging bees to take care of larval babies again?”

Blamed for Bee Collapse, Monsanto Buys Leading Bee Research Firm


Friday, 20 April 2012 07:56

‘Monsanto, the massive biotechnology company being blamed for contributing to the dwindling bee population, has bought up one of the leading bee collapse research organizations.

Recently banned from Poland with one of the primary reasons being that the company’s genetically modified corn may be devastating the dying bee population, it is evident that Monsanto is under serious fire for their role in the downfall of the vital insects.

It is therefore quite apparent why Monsanto bought one of the largest bee research firms on the planet.’

Death of the Bees. Genetically Modified Crops and the Decline of Bee Colonies in North America


Wednesday, 10 August 2011 05:15

‘Commercial beehives pollinate over a third of [North}America’s crops and that web of nourishment encompasses everything from fruits like peaches, apples, cherries, strawberries and more, to nuts like California almonds, 90 percent of which are helped along by the honeybees. Without this pollination, you could kiss those crops goodbye, to say nothing of the honey bees produce or the flowers they also fertilize’.

This essay will discuss the arguments and seriousness pertaining to the massive deaths and the decline of Bee colonies in North America. As well, it will shed light on a worldwide hunger issue that will have an economical and ecological impact in the very near future.’
