- Scientists identify 36 genes, 100 neuropeptides in honey bee brains
10-25-2006 · EurekAlert!
From humans to honey bees, neuropeptides control brain activity and, hence, our behaviors. Understanding the roles these peptides play in the life of a honey bee will assist researchers in understanding the roles they play in their human counterparts.

- Cities change the songs of birds
12-04-2006 · EurekAlert!
By studying the songs of a bird species that has succeeded in adapting to urban life, researchers have gained insight into the kinds of environmental pressures that influence where particular songbirds thrive, and the specific attributes of city birds that allow them to adjust to noisy urban environments. The findings, reported by Hans Slabbekoorn and Ardie den Boer-Visser of Leiden University, appear in the December 5 issue of Current Biology.

- Low levels of neurotransmitter serotonin may perpetuate child abuse across generations
11-02-2006 · EurekAlert!
Infant abuse may be perpetuated between generations by changes in the brain induced by early experience, research shows. A research team found that when baby rhesus monkeys endured high rates of maternal rejection and mild abuse in their first month of life, their brains often produced less serotonin, a chemical that transmits impulses in the brain. Low levels of serotonin are associated with anxiety and depression and impulsive aggression in both humans and monkeys.

- UCLA: How does your brain respond when you think about gambling or taking risks?
01-25-2007 · EurekAlert!
Should you leave your comfortable job for one that pays better but is less secure? Should you have a surgery that is likely to extend your life but poses some risk you will not survive the operation? In the Jan. 26 issue of the journal Science, UCLA psychologists present the first neuroscience research comparing how our brains evaluate the possibility of gaining versus losing when making risky decisions.

- Key to longer life (in flies) lies in just 14 brain cells
09-20-2007 · EurekAlert!
Fruit flies live significantly longer when the activity of the protein p53 is reduced in just 14 insulin-producing cells in their brains, new Brown University research shows. The results put scientists one step closer to understanding caloric restriction, a biochemical process proven to slow aging. Results appear in the Proceedings of the National Academy of Sciences.

- New bird, bat species revealed by extensive DNA barcode studies
02-18-2007 · EurekAlert!
At unprecedented levels of difficulty involving highly biodiverse and continent-sized landscapes, scientists have successfully tested their ability to identify and DNA "barcode" entire assemblages of species -- the prelude to a genetic portrait of all animal life on Earth.

- Land conversion and climate threaten land birds
06-04-2007 · EurekAlert!
Evaluating changes in range size of land bird species using Millenium Ecosystem Assessment scenarios reveals that land conversion, as well as climate change, will lead to the decline of many species, particularly those in the tropics.

- Naturally occurring enzyme can break down key part of Alzheimer's plaques
10-24-2006 · EurekAlert!
Scientists have identified a naturally occurring enzyme that can break down a key component of the brain plaques characteristic of Alzheimer's disease. The finding may provide researchers with new opportunities to understand what goes wrong in the brains of Alzheimer's patients and could one day help them seek new therapies.
