At certain "locations" in spacetime, there is a wormhole such that, if you jump in, you'll emerge at some point in the past. To the best of our knowledge, these time loops are not ruled out by the laws of physics.
With Congressional partisanship reaching unprecedented levels and science too frequently under attack from a vocal minority, it's all the more vital to stand up for the basic idea that our choices should be informed by the best evidence and data available.
The world's oceans are vast, covering 71 percent of the Earth's surface and containing 97 percent of the water, yet only about 5 percent of the ocean and its depths have been explored.
It's the holiday season, and we'll soon be decorating our home with greenery -- holly sprigs, poinsettia, maybe a mistletoe, and of course the tree, probably some kind of spruce. What we are doing in effect is creating a treacherous world for our youngest revelers to explore.
When will we be able to floor the accelerator and get to another star system in a time that's short enough that the crew doesn't lose interest or simply start killing one another?
The Communist Party has long craved a homegrown Nobel science prize; evidence of a technological power to match its economic might and a vindication of the astonishing £243 billion China has poured into the development of science and technology in the last seven years.
I know there is a segment of the population that has expressed intense concern over vaccines in general and that this is an emotional issue for some. But based on the science, my personal view is that the benefits of the HPV vaccine far outweigh its risks.
We are the only species on this planet with the foresight capable of deliberately plotting a path toward a desirable long-term future. Plan it for the apes; because they can't.
The milestone of our third mirror captures more than a moment in time, it heralds a rapidly approaching period of discovery.
What began as a planetary physicist's chance encounters with skaters at the park is turning into a full-fledged science outreach program.
Little real evidence is available to indicate that the brains of men and women are "hardwired" differently, yet, perhaps due to lingering stereotypes, women remain underrepresented in the science, technology, engineering and math (STEM) fields.
Human intervention in growing food crops is really part of our history. For hundreds, perhaps even thousands of years, we have modified and improved crop varieties to meet our ever-evolving tastes and needs.
The far right can stick their collective heads in the sand and talk about American exceptionalism, but the rest of the world is getting educated in the meantime. America is indeed number one -- in self-delusion.
If you're looking for "a whole new way of killing cancer," don't turn to the journals. You'll find it in Esquire.
Researchers have found links between certain genes and a football player's susceptibility to getting a concussion. It's a scientific detective story, of sorts.
Chimpanzees have languished in laboratories for decades, sometimes subjected to painful experimentation and often warehoused in barren cages. But now the fate of these remarkable and highly intelligent beings has taken a monumental turn for the better.
Today we celebrate the life and legacy of Nelson Mandela. It is worth reflecting on his ability to transcend politics when speaking about contentious scientific issues. Nowhere was this more apparent than in the difficult politics surrounding HIV/AIDS at the turn of the millennium.
There is much that remains to be learned about the evolutionary process. Many problems remain without known solutions. But the sources of genome variation, including rapid changes throughout the genome, are no longer mysterious.
The discovery (if and when it happens) of extraterrestrial complex life will undoubtedly usher in a revolution that will rival the Copernican and Darwinian revolutions combined.
