Some pollens are much more aggressive than others There are pollens — and there are pollens, as scientists from across Europe discovered while investigating the allergic potential of pollens from the three main triggers of hay fever in Europe: birch, grass and olive. Different people can have very different allergic reactions to a particular type of pollen, however, and as the Hialine study researchers have now found, the allergenicity of the pollens also varies. Depending on the...

How Flowers Pollinate With Precision
2012-05-17 11:25:35

Next Mother's Day, say it with an evolved model of logistical efficiency – a flower. A new discovery about how nature's icons of romance manage the distribution of sperm among female gametes with industrial precision helps explain why the delicate beauties have reproduced prolifically enough to dominate the earth. In pollination, hundreds of sperm-carrying pollen grains stick to the stigma suspended in the middle of a flower and quickly grow a tube down a long shaft called a style...

First Record Of 1 Million Year Old Pollinating Insects Discovered
2012-05-16 04:27:26

A new study, conducted at the European Synchrotron Radiation Facility (ERSF), details the first recorded cases of pollination by insects. Scientists discovered many insects coated in specks of pollen within two pieces of amber dating back to 110 to 105 million years ago in northern Spain. Amber is the only medium that can contain such highly detailed features such as pollination over millions of years. The team of international scientists includes Xavier Delclòs from the...

Image Credit: Photos.com --- Brett Smith for Redorbit.com Agricultural researchers in the UK made a plea to environmental protesters on Tuesday in an attempt to dissuade them from carrying out threats to destroy experimental genetically modified (GM) wheat. A protest movement called Take the Flour Back has called for a “decontamination” of an experimental wheat field just north of London that was planted by Rothamsted Research, a publicly funded agricultural research...

From Reykjavik to Thessaloniki, pollen levels are on the increase. A team of researchers headed by Prof. Annette Menzel at the Technische Universitaet Muenchen reports that pollen counts have already risen across Europe in recent years. Their findings are based on an analysis of pollen time series in 13 countries (PLoS ONE). This trend is more pronounced in urban areas, where pollen counts are rising by an average of around three percent per year compared with one percent per year in rural...

Allergic disease affects as many as 40-50 million Americans. During spring, many people with untreated allergic symptoms are unaware of how much better they can feel and see once their symptoms are properly diagnosed and managed. Most trees and grasses release pollen in the spring and summer. The warmer temperatures associated with climate change may be causing plants to grow faster, bloom earlier and produce more pollen. This results in longer allergy seasons, as well as increased allergy...

Pollen Can Protect Mahogany From Extinction
2012-04-04 03:28:58

New research from the University of Adelaide could help protect one of the world's most globally threatened tree species - the big leaf mahogany - from extinction. Big leaf mahogany (Swietenia macrophylla) is the most prized mahogany timber around the world. It is at risk of extinction in its native habitats because of the timber trade, particularly in Central and South America. To better understand how such a threatened species can be brought back from the brink of extinction,...
