UC Berkeley seismologists just released an app that can detect magnitude 5 earthquakes up to 6.2 miles away. The software differentiates real tremors from everyday motion, with 93 percent accuracy.

2016 marks the 50th anniversary of Star Trek. And to boldly go where no man has gone before, physicist Philip Lubin has outlined a way to propel spacecraft using photon propulsion instead of NASA’s current chemical propulsion.

Researchers in Belgium examined the immune systems of 670 people and found a 50% decrease in variation among couples living together compared to randomly paired individuals.

Thanks to the hyper-sensitive camera on the CFH Telescope in Hawaii, French astronomers have discovered an enormous plume of gas tailing a galaxy in the Virgo Cluster.

Now that astronaut Scott Kelly is back on earth, scientists are studying how all that time altered his body.

NASA released a spectacular image of a large dying WR star and its blue bubble nebula. The WR star is 30,000 light-years from Earth and is at least 20 times the mass of the Sun.

Researchers found the first gene associated with gray hair. After studying the genomes of more than 6,600 people from Latin America, the research team were able to identify the genes linked to different hair qualities, including graying.

In Indonesia, scientists captured the only total eclipse of 2016. Other than looking very cool, solar eclipses actually allow us to see the outer region of the Sun's atmosphere, helping scientists understand the rare astronomical phenomena.

A set of comets recently flew by Earth. The closest was 2.2 million miles away from our planet's surface. NASA believes it will be 150 years before another comet flies within this proximity.

A Harvard study revealed that most people are not aware of harboring a gender bias. The study found that teenage girls preferred male political leaders and that men receive more credit for their professional work than women.
