The pleasures of musical experience studied

(04/25/13 11:26pm)

Have you ever wondered if that amazing feeling you get while listening to your favorite song is anything like what others experience when they listen to their favorite music? There is a pleasure associated with those songs that we do not get by listening to random sounds put together. Researchers found that when we are indulging ourselves with some sweet melody, the auditory cortex is not the only part of the brain activated: emotion-associated regions and reward circuits are also stimulated.

Database expedites diagnoses of rare diseases

(03/28/13 5:57pm)

As the field of genetics has burgeoned in the past decade with new gene analyzing technologies, it seems as though we are discovering new genes every day that are responsible for diseases like Alzheimer’s and schizophrenia. With the massive amount of genetic data studied each day, it has become difficult for various gene labs to collaborate and organize new genetic information in a coherent manner.

Identity of placental mammal ancestor reconstructed

(02/21/13 11:52pm)

Have you ever wondered what the common ancestor of all placental mammals looked like? A recent study shows that we are descendants of a rat-like mammal that weighed no more than half a pound, displayed a long, furry tail and dined mostly on insects.

Environmental changes pressure viruses

(02/14/13 8:26pm)

We have all noticed that the temperature has been sporadically changing; one day it’s hot enough to put on our shorts, and the next, we would be freezing without our winter jackets. The random fluctuation in temperatures could turn out to have a larger impact than we thought. Recent studies showed that even viruses, which typically adapt more easily than mammals, failed to adapt when exposed to a random pattern of temperatures.

Ozone holes affect ocean patterns

(02/08/13 1:52am)

Hopkins scientists found that the thinning of ozone in our atmosphere has been responsible for changes in the ocean circulation, bringing “old” water to the surface of the ocean. This has had a significant impact on the amount of carbon dioxide in the air.

Muscle regeneration possible without stem cells

(10/12/12 2:48am)

Until now, no cure was available for muscular dystrophy. However, recent research findings are about to change that. Se-Jin Lee, from the Hopkins School of Medicine, published an article in Proceedings of the National Academy of Sciences about a promising solution for muscle hypertrophy that does not involve stem cells.
