With his signature on a novel Medicaid-for-all-type bill, Nevada Gov. Brian Sandoval could rewrite the way many of his constituents get healthcare, and establish a model that other states might eventually follow in the absence of congressional action to fix or replace Obamacare.

A thaw is underway in Russia, and it has nothing to do with presidential politics. Inside a cave in Russia's Ural Mountains, where Europe and Asia meet, a team of UNLV researchers has found evidence of steady warming since the end of the last ice age.

Police officers are trained to serve and protect the community, but this week's arrest of a Metro officer for choking a man to death could affect other cops on the beat. The question tonight: will they second-guess their actions?

Practically everyone who likes space and has lots of money is trying to get to Mars in the near future. But before anyone reaches the Red Planet, there are plenty of concerns to mull over, most notably that our bodies were not built to live in a barren litter box with a thin atmosphere. But the journey to Mars is an equal concern. An unnerving new study suggests that the trip to Mars could put passengers at a higher risk to develop cancer—possibly two times greater than what experts previously thought.

Jenny Hurtado, a young Hispanic woman from Las Vegas, has overcome all sorts of adversities that have come to her in life, and today this young woman who is a recent graduate of the University of Nevada Las Vegas, has created a scholarship to help undocumented students from the valley.

Everyone is well aware that sending humans to Mars means overcoming a number of major problems, one of which is the cancer risk for the astronauts. But it seems that even NASA's best risk projections were way off the mark. The latest research suggests the cancer risk is actually double what we thought.

'Exploring Mars will require missions of 900 days or longer and includes more than one year in deep space where exposures to all energies of galactic cosmic ray heavy ions are unavoidable,' UNLV scientist Francis Cucinotta, a leading scholar on radiation and space physics, explained.

Astronauts hoping to take part in a crewed mission to Mars might want to pack some additional rad tablets! Long before NASA announced their proposal for a “Journey to Mars“, which envisions putting boots on the Red Planet by the 2030s, mission planners have been aware that one of the greatest risks for such a mission has to do with the threat posed by cosmic and solar radiation.

The cancer risk for a human mission to Mars may be double what was previously expected, says a new study that is partly based on studying tumors in mice. Astronauts are exposed to radiation from galactic cosmic rays when they travel outside the protective shield of Earth’s magnetic field. These cosmic rays — which originate from the shockwaves of star explosions, or supernovas — can disrupt the bonds inside human cells, leading to DNA damage and mutation.
