Last week NASA scientists put the space telescope Kepler in a kind of technological coma. The craft, designed to search for Earth-like planets orbiting stars in our cosmic neighborhood (within a few thousand light-years, that is), failed and seems to be unfixable. But it has left us with an undeniable legacy.

Can we act backwards in time? We can if we're talking about the world of quantum particles! It seems that the human mind plays a role in this time puzzle, too. Our role may even have something to do with why the universe exists.

Confronted with the amazing advances made by science, why do so many still cling to God as a creator? Could the answer be that we need to be created in order to be special? Or are we afraid of our own unique place in the Universe? Marcelo Gleiser knows what he thinks.

Improvements in science education can take many forms. Commentator Marcelo Gleiser says that one of the easiest and most rewarding is to simply put real research scientists in front of students. A few volunteer hours from a scientist can change how a student sees the world forever.

Physicist Marcelo Gleiser recalls his early interest in competing interpretations of the quantum world. Now a successful researcher in his own right, he wonders if its time to switch gears and turn his casual interest into a professional pursuit.

How do you explain it when unseen forces act across time and space? The fact is that reality is far stranger than we can suppose when we step into the quantum world. Physicist Marcelo Gleiser lays out the bones of this modern ghost story.

Is the importance of life on Earth shrinking as science continually re-defines our world as a meaningless speck in an endless and uncaring Universe? Or is life here a precious thing that grows in importance with our ever-deepening knowledge of the Universe? Commentator Marcelo says it's the latter.

Science discovers one dark material after another, making reality stranger than fiction. Commentator Marcelo Gleiser says the recent observation of the Higgs field and last week's announcement of the possible detection of dark matter are just the latest data points in our long quest to know what the Universe is made of.

What can we say about how the brain creates our sense of self? A lot and yet surprisingly little, as it turns out. Commentator Marcelo Gleiser ponders the many challenges scientists face to make sense of our mind.

Can science ever explain the origin of the Universe? Commentator Marcelo Gleiser suggests caution and humility as scientists face this very difficult question.

Results from the European Planck satellite point to an older and slower universe. Commentator Marcelo Gleiser says the data gives us confidence that cosmology is on the right track to explain the Universe in which we live.

Can science explain the origins of the universe, of life and of the mind? Not completely, it turns out. But how far can it go in answering them? Commentator Marcelo Gleiser starts digging into these questions.

Is math a truth or a human invention? In this age-old question lies an interesting analogy with sports, and perhaps a resolution to the conundrum. Updated with sources for further reading on the math as invention vs. discovery controversy.

As scientists advance their understanding of how the Earth has changed through billions of years, it becomes increasingly clear that the Earth and the life on it are entwined in unique ways. Commentator Marcelo Gleiser goes in search of the origins of life in a meeting of the minds at CERN.

Scientists have found a Higgs-like particle, a key component in modern physics theory. But is it the Higgs particle, or a new one, part of a more complex model?

The mathematician Charles Lutwidge Dodgson posed a big question about mirrors in one of his best-known books: Through the Looking-Glass (yup, Dodgson's pen name was Lewis Carroll). Natasha Gostwick of Storynory reads an excerpt that gets at the heart of the trouble: is mirror milk any good to drink? ...

Just after the Big Bang, the universe was a primordial soup made of light. Then, it started belching out matter. Neil deGrasse Tyson explains how deeply shocking this is, and Marcelo Gleiser reveals an imperfection in the laws of physics that makes our very existence possible.
