Sleeping is often considered one of the most primitive and mundane aspects of biological existence. Some scientists claim that it is a survival instinct that has evolved for millions of years. However, despite its ancestral roots, sleep is not very well understood. In fact, countless mysteries take place when we sleep: How does the mind create dreams? Do dreams come in colors or black-and-white? Most importantly, how does the brain sustain and maintain high levels of activity during certain periods of the sleep cycle?

Chiral molecules found on Murchison meteorite

By JAEMIE BENNETT | September 6, 2018

As the only known planet with life, it makes sense to assume that life began on Earth. Numerous experiments have recreated the environment of the early Earth and determined that biological molecules could have first formed on our planet.

PUBLIC DOMAIN Bone marrow in the skull has been identified to contribute greatly to the migration of immune cells.

Immune cells do not have a homogenous response

By ISAAC CHEN | September 6, 2018

In human diseases and injuries, inflammation is a critical defense and repair mechanism. In response to a physical injury or infection, immune cells are recruited to the site of inflammation to defend against the foreign injury or pathogen. However, immune cells also have destructive properties. Persisting inflammation can create an opposite effect, causing more harm than benefit.

PUBLIC DOMAIN   CDC recently released statistics on increasing STD diagnoses across the nation.

National number of STD cases continues to climb

By CINDY JIANG | September 6, 2018

For the past half-decade, statistics for the number of sexually transmitted disease (STD) diagnoses have shown an upward trend. All together, the numbers for novel cases of chlamydia, gonorrhea and syphilis total to nearly 2.3 million for 2017 in the United States alone. 

PUBLIC DOMAIN Mono virus attacks B cells, which produces proteins to turn genes on and off.

New diseases found to be linked to mono virus

By ANNA CHEN | May 3, 2018

Mononucleosis is caused by the Epstein-Barr virus (EBV), which is estimated to infect 90 percent of people in the U.S. by age 20 and 90 percent of the people in developing countries by the age of two. Ninety-eight percent of the world’s population carries EBV, since once it infects, it remains in a person for the rest of their lives.

By CATHERINE PALMER | May 3, 2018

According to National Geographic, “You have a one in 63 chance of dying from the flu and a one in 3,700,000 chance of being killed by a shark during your lifetime.” And yet, do we fear the flu? No. But we’re convinced that we may very well be fatally attacked by a shark whenever stepping foot in the ocean.

3-D brains offer new way to study mental illnesses

By ISAAC CHEN | May 3, 2018

While there is currently no cure for schizophrenia, research has continued to develop new ways of understanding this disease. In fact, researchers at Brigham and Women’s Hospital (BWH) in Boston have recently used induced pluripotent stem cells (iPSCs) and embryonic stem cells to develop 3-D cerebral organoids, which are artificially grown models of the brain.
