"Salmon are famous for their swims upriver to spawn. Many people focus on this amazing feat of stamina, but even more remarkable is their ability to switch from living in freshwater to seawater, and back again. Most fish make their homes in just one type of water. So how do salmon do it? A team of biologists at Skidmore College, the U.S. Geological Survey, and the University of Gothenburg recently uncovered changes in the expression of certain genes that explain in part how Atlantic salmon make the transition. Atlantic salmon are born in freshwater, and between the ages of one and four migrate downstream to the sea. Before starting this migration, the fish undergo a months-long process preparing them for life in seawater. This is called smoltification. During this time, fish develop gill cells called ionocytes that contain specialized proteins that pump out excess salt..."

"Falls are a major public health threat among older adults Exercise interventions are one of the most effective ways to prevent falls in the community But these interventions depend on early identification of those at high risk for falling One useful tool physiotherapists can use to spot vulnerable individuals is gait speed A gait speed under 1.0 m/sec has been well correlated with an increased fall risk in the elderly Now, researchers have shown that using a gait-speed cut-off of 1.0 m/sec captures several other modifiable risk factors for falls including a multiple-fall history, depressive symptoms, and a high number of medications The results support gait speed assessment as an interdisciplinary single test to identify individuals who would benefit from guided fall-preventive exercise Kyrdalen, et al. Associations between gait speed and well-known fall-risk factors amongst community-dwelling older adults..."

You may have heard it called pot, weed, grass, ganja or skunk, but marijuana by any other name is still a drug that affects the brain. Did you know marijuana can cause some people to lose focus on events around them? It makes others more aware of their physical sensations, and it has still more effects on other people. All these different changes are caused by chemicals that affect the brain. More than 400 chemicals are in the average marijuana plant. When smoked, heat produces even more of them!

Short Description:
In this survey text, directed at those not majoring in biology, we dispel the assumption that a little learning is a dangerous thing. We hope that by skimming the surface of a very deep subject, biology, we may inspire you to drink more deeply and make more informed choices relating to your health, the environment, politics, and the greatest subject that are all of us are entwined in, life itself.

This animation describes the formation of endocrine glands starting with the mitosis of mesenchymal tissues, eventually leading to the formation of the secretory portion of the gland by differentiation.

Methamphetamine is a powerful drug. It acts by changing how the brain works. It also speeds up many functions in the body. Methamphetamine has a chemical structure that is similar to another drug called amphetamine that I explore in my magazine on stimulants. Methamphetamine can cause lots of harmful things, including inability to sleep, paranoia, aggressiveness, and hallucinations.

During the past decade, there have been dramatic advancements in the brain and cognitive sciences. For the first time, understanding how the brain works has become a scientifically achievable goal. In this new lecture series, Grey Matters: Molecules to Mind, San Diego's leading Neuroscientists explore the human brain. The first lecture in this series addresses an issue that has often been absent in these discussions: what role do stem cells play in development of the brain? (59 minutes)

UCSD cognitive scientist Martin Sereno takes you on a captivating exploration of the brain's structure and function as revealed through investigations with new advanced imaging techniques and understandings of evolution. (57 minutes)

In this activity, learners explore their eye pupils and how they change. Learners use a magnifying glass, mirror, and flashlight to observe how their pupil changes size in response to changes in lighting. Learners also experiment to determine how light shining in one eye affects the size of the pupil in their other eye. This resource guide includes background information about pupils and why they change as well as information related to emotional stimuli, involuntary reflexes, and photography.
