How plants 'mate' for life and repel other suitors
Japanese researchers are astounded and surprised by the technical sophistication of plant systems, specifically the details of the pollen tube development system.
In addition to the signal that promotes attraction between individuals, Mizuta and her colleagues were also surprised to find a repulsion signal. This signal was emitted upon attracting a pollen tube, discouraging the further attraction of additional pollen tubes. In addition to the 45-minute blocking process that prevents multiple sperm from fertilizing the same ovule, a repulsion signal also directs rejected suitors towards other unpaired ovules.
"I find the repulsion system fascinating," Mizuta said. "The cells that generate the attraction system are mostly synergid cells, whereas the cells that generate the repulsion system include multiple types such as somatic and gametophytic cells at multistep levels. I find it very interesting that all couplings involve this mechanism of attracting and repelling."
Unfortunately the published story falls short of giving credit to the great Designer and Engineer of these systems.
There were a number of great articles the last issue of Israel My Glory - May/June 2024 edition.
Gives a brief history of Israel's many defensive wars since 1948.
- war for independence (1948)

Provides some helpful history regarding Hamas, Hezbollah, and the PA.
The United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) has come under intense scrutiny following the revelation that approximately 10% of its 12,000 workers in Gaza are linked to Hamas, and at least 12 participated directly in the terrorist group's October 7, 2023, massacre in Israel.
