Question 1: In one sentence, what was the research about?

Answer 1: How dancing or physical exercise done by elders can have an anti-aging effect on the brain.

Question 2: How many subjects were used in the experiment?

Answer 2: It just says elderly volunteers, with an average age of 68, it doesn’t say a specific number of subjects.

Question 3: Was there a control group?

Answer 3: Yes, there was two different groups each elderly could be assigned to, and they both involved training to.

Question 4: How were the subjects chose?

Answer 4: They were recruited, volunteers.

Question 5: What did the experimenters do to the subjects?

Answer 5: Both groups had to go through 18-month weekly course of either learning dance routines, or endurance and flexibility training.

Question 6: How did the subjects react?

Answer 6: Both groups showed an increase in the hippocampus region of the brain.

Question 7: Did the subjects act the way the experimenters expected?

Answer 7: Yes, because the experimenters proved that dancing and physical exercise can prolong the aging life of the brain.

Question 1: In one sentence, what was the research about?

Answer 1: Experimenters have revealed how eating stimulates brain’s endogenous opioid system to signal pleasure.

Question 2: How many subjects were used in the experiment?

Answer 2: Does not say how many subjects there were.

Question 3: Was there a control group?

Answer 3: Yes, there was because the subjects were injected with a radioactive compound binding to their brain’s opioid receptors.

Question 4: How were the subjects chosen?

Answer 4: Does not say how the subjects were chosen.

Question 5: What did the experimenters do to the subjects?

Answer 5: There subjects were injected with a radioactive compound binding to their brain’s opioid receptors. The brain was then measured three times with a PET camera: after a palatable meal, after a non-palatable meal, and then after an overnight fast.

Question 6: How did the subject react?

Answer 6: It does not say how the subjects react to the experiment.

Question 7: Did the subjects act the way the experimenters expected?

Answer 7: They did because they proved that eating stimulates the brain’s endogenous opioid system.

Question 1: In one sentence, what was the research about?

Answer 2: Children that are excluded from school may lead to long-term psychiatric problems and psychological distress.

Question 2: How many subjects were used in the experiment?

Answer 2: Thousands of children.

Question 3: Was there a control group?

Answer 3: No, there was not a control group.

Question 4: How were the subjects chosen?

Answer 4: They were chosen on if they were excluded from school.

Question 5: What did the experimenters do to the subjects?

Answer: They experimenters researched on the brains function on how it responded to school.

Question 6: How did the subjects react?

Answer 6: They subjects showed psychological distress.

Question 7: Did the subjects act the way the experiments expected?

Answer 7: It does not say if the subjects acted the way the experimenters expected or not.

Question 1: In one sentence, what was the research about?

Answer 1: Experimenters researched the pathway of interdomain communication in a family of proteins, trying to develop new anti-cancer drugs, antibiotics and treatments for Alzheimer’s and Parkinson’s diseases.

Question 2: How many subjects were used in the experiment?

Answer 2: They used a family of proteins.

Question 3: Was there a control group?

Answer 3: Yes, because the protein group has to be watched often for change.

Question 4: How were the subjects chosen?

Answer 4: They chose the protein Hsp70s because they are more likely help aid in antibiotic, and treatments for Alzheimer’s.

Question 5: What did the experimenters do to the subjects?

Answer 5: They had to study the movement of the protein, so they used a technique called molecular dynamics.

Question 6: How did the subjects react?

Answer 6: The technique they used gathered data that proved the simulations for the proteins.

Question 7: Did the subjects act the way the experimenters expected?

Answer 7: Yes, the proteins worked and are just like putting a puzzle together because everything worked and fit together to verify the simulations done to the proteins worked. Now the experimenters are one step closer to finding a way to make anti-cancer drugs, antibiotics, and treatments for Alzheimer’s and Parkinson’s disease.
