Is energy released in alpha decay? The energy released in this α decay is in the MeV range, about 106 times as great as typical chemical reaction energies, consistent with many previous discussions. Most of this energy becomes kinetic energy of the α particle (or 4He nucleus), which moves away at high speed. Is energy […]
How might predator/prey relationships affect light pollution?
How might predator/prey relationships affect light pollution? Summary: A new study provides strong evidence that exposure to light pollution alters predator-prey dynamics between mule deer and cougars across the intermountain West, a rapidly growing region where nighttime skyglow is an increasing environmental disturbance. When the environment has reached its carrying capacity for the human population […]
What are the two main barriers against implementing a renewable energy system?
What are the two main barriers against implementing a renewable energy system? The Siting and Transmission However, they can still present two primary barriers to renewables namely siting and transmission. What are the barriers in implementing alternative fuels? Alternative Fuel Vehicles Are Expensive. New technologies almost always require a high level of front-end capital investment. […]
Are sensation and perception the same thing?
Are sensation and perception the same thing? Sensation occurs when sensory receptors detect sensory stimuli. Perception involves the organization, interpretation, and conscious experience of those sensations. How do you test for unconscious proprioception? Position sense (proprioception), another DCML sensory modality, is tested by holding the most distal joint of a digit by its sides and […]

How can we protect the cryosphere?
How can we protect the cryosphere? By quickly taking steps to curb emissions from cookstoves, forest burning, fossil fuel extraction and diesel transport countries could help preserve the cryosphere while at same time saving the lives and health of millions. What would happen if the cryosphere melted? Unsurprisingly, water from the current cryosphere melt is […]
How does angle affect work?
What is an experimental control example?
What is an experimental control example? Experimental controls are used in scientific experiments to prevent factors other than those being studied from affecting the outcome. For example, suppose a researcher feeds an experimental artificial sweetener to thirty laboratory rats and observes that eight of them subsequently die of dehydration. Why is it important to have […]
