The largest moon in our solar system, a companion to Jupiter named Ganymede, might have ice and oceans stacked up in several layers like a club sandwich, according to new NASA-funded research that models the moon's makeup.

Tracing where your DNA was formed over 1,000 years ago is now possible, thanks to a revolutionary technique. The ground-breaking Geographic Population Structure tool works similarly to a satellite navigation system as it helps you to find your way home, but not the one you currently live in -- but rather your actual ancestor's home from 1,000 years ago.

Researchers have discovered that stem cells taken from teeth can grow to resemble brain cells, suggesting they could one day be used in the brain as a therapy for stroke.

Engineers have successfully grown -- for the first time -- fully functional human cartilage in vitro from human stem cells derived from bone marrow tissue. Their study demonstrates new ways to better mimic the enormous complexity of tissue development, regeneration, and disease.

For the first time an international team of astronomers has measured circular polarization in the bright flash of light from a dying star collapsing to a black hole, giving insight into an event that happened almost 11 billion years ago.

The galaxy known as M87 has a fastball that would be the envy of any baseball pitcher. It has thrown an entire star cluster toward us at more than two million miles per hour. The newly discovered cluster, which astronomers named HVGC-1, is now on a fast journey to nowhere. Its fate: to drift through the void between the galaxies for all time.

Progress has been made toward understanding the physiological mechanisms that underlie Gulf War illness and identifying possible treatments, says a new report on Gulf War Veterans' Illnesses, a condition that affects as many as 250,000 veterans of the 1990-91 Gulf War. Gulf War illness refers to the chronic symptoms that affect veterans of that conflict at markedly elevated rates, compared to other veterans' groups and to the U.S. population as a whole. Symptoms can vary from person to person, but typically include some combination of widespread pain, headache, persistent problems with memory and thinking, fatigue, breathing problems, stomach and intestinal symptoms, and skin abnormalities.

Would you sacrifice one person to save five? Such moral choices could depend on whether you are using a foreign language or your native tongue. A new study from psychologists finds that people using a foreign language take a relatively utilitarian approach to moral dilemmas, making decisions based on assessments of what's best for the common good.

A spider expert has described a new species: Cebrennus rechenbergi. It is the only spider that is able to move by means of flic-flac jumps. The flic-flac spider uses its legs to create a rolling motion. Like a gymnast, it propels itself off the ground, followed by a series of rapid flic-flac movements of its legs.

Despite overwhelming scientific evidence for the impending dangers of human-made climate change, policy decisions leading to substantial emissions reduction have been slow. New research shows that even as extreme weather events influence those who experience them to support policy to address climate change, waiting for the majority of people to live through such conditions firsthand could delay meaningful action by decades.

In a study of nearly 1,000 mother-child pairs, researchers found that prenatal exposure to selective serotonin reuptake inhibitors (SSRIs), a frequently prescribed treatment for depression, anxiety and other disorders, was associated with autism spectrum disorder and developmental delays in boys.
