I have been employed by a charity organization for less than a year now and I have the privilege of finding foster homes for abandoned children. It has always been my dream to work with adopted children because I myself was an adopted child.
I was born in California in September of 1976 and was adopted in Ohio in March of 1977. I have no memory of being told that I was adopted, however, I have always known. I have been told that I was wanted and I was special.
Even though my parents provided me with lots of love, I was always annoyed by the questions about my origin and my feeling of being unwanted. I constantly scanned every crowd I was in for another human that looked like me or laughed like me.
I began searching for my birthparents in 1999 and I imagined every possible scene of my birth family.
I went to a local agency for support and five days later I met my birth mother. The story unfolded. She flew me to Los Angeles the next day and I spent the weekend connecting with another person who looked just like me. We have had a worthwhile relationship over the past years although she could not give me any information about my birth father.
In June of last year a member of my birth father’s family contacted me. Now, he and I are just beginning to get to know what it is like to be a birth child, Without the support of my parents who raised me I would have never experienced the feeling of being truly wanted accepted. For that, I am forever grateful.

Plants can’t communicate by moving or making sounds, as most animals do. Instead, plants Produce volatile compounds, chemicals that easily change from a liquid to a gas. A flower’s sweet smell, for example, comes from volatile compounds that the plant produces to attract insects such as Bugs and bees.

Plants can also detect volatile compounds produced by other plants. A tree under attack by Hungry insets, for instance, may give off volatile compounds that let other trees know about the Attack. In response, the other trees may send off chemicals to keep the bugs away ——or even  Chemicals that attract the bugs’ natural enemies.

Now scientists have created a quick way to understand what plants are saying: a chemical Sensor（传感器）called an electronic nose. The “e-nose” can tell compounds that crop plants make When they’re attacked Scientists say the e-nose could help quickly detect whether plants are being Eaten by insects. But today the only way to detect such insects is to visually inspect individual Plants. This is a challenging task for managers of greenhouses, enclosed gardens than can house Thousands of plants.

The research team worked with an e-nose than recognizes volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds Based on these interactions, the e-nose gives off electronic signals that the scientists analyze using computer software.

To test the nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all common greenhouse crops. Then scientists collected samples of air around damaged leaves from each type of crop, These plants had been damaged by insects, or by scientists who made holes in the leaves with a hole punch（打孔器）. The e-nose, it turns out, could identify healthy cucumber, pepper and tomato plants based on The volatile compounds they produce, It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage ---- by insects or with a hole Punch ---- had been done to the tomato leaves.

With some fine-tuning, a device like the e-nose could one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A device like this could also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareva, a biochemist at Purdue University in West Lafayette, Ind. who studies smells of flowers and plants. Hopefully, scientists believe, the device could bring large benefits to greenhouse managers in the near future.
