  1. The Economist asks: How has DNA shaped the human race?

    Jason Palmer, editor of the Espresso daily-briefing app, is joined by geneticist and broadcaster Adam Rutherford to get to the bottom of the stories told by human DNA. They discuss the genetics of sprinters, the misguided nature v nurture debate and how promiscuous humans’ forebears were.

  2. Sara Seager: Other Earths. Other Life. - The Long Now

    We are one tool away from learning which distant planets already have life on them and which might be welcoming to life.

    MIT Planetary Scientist Sara Seager is working on the tool. She is chair of the NASA team developing a “Starshade” that would allow a relatively rudimentary space telescope to observe Earth-size planets directly, which would yield atmospheric analysis, which would determine a planet’s life-worthiness.

    Despite 1,000-plus exoplanet discoveries by the Kepler spacecraft and the hundreds more expected from the Transiting Exoplanet Survey Satellite after 2017, neither instrument can make detailed observation of the atmosphere of small rocky planets, because each star’s brilliance overwhelms direct study of the rocky motes that might harbor life. A Starshade cures that.

    A former MacArthur Fellow, Seager is author of Exoplanet Atmospheres (02010) and an astrophysics professor at MIT. Her maxim: “For exoplanets, anything is possible under the laws of physics and chemistry.”

  3. BBC Radio 4 - The Life Scientific, EO Wilson

    E O Wilson has been described as the "world’s most evolved biologist" and even as "the heir to Darwin". He’s a passionate naturalist and an absolute world authority on ants. Over his long career he’s described 450 new species of ants.

    Known to many as the founding father of socio-biology, E O Wilson is a big hitter in the world of evolutionary theory. But, recently he’s criticised what’s popularly known as The Selfish Gene theory of evolution that he once worked so hard to promote (and that now underpins the mainstream view on evolution).

    A twice Pulitzer prize winning author of more than 20 books, he’s also an extremely active campaigner for the preservation of the planet’s bio-diversity: he says, "destroying rainforest for economic gain is like burning a Renaissance painting to cook a meal".

    E O Wilson talks to Jim al-Khalili about his life scientific.

  4. Big Picture Science: Long Live Longevity

    Here’s to a long life – which, on average, is longer today than it was a century ago. How much farther can we extend that ultimate finish line? Scientists are in hot pursuit of the secret to longer life.

    The latest in aging studies and why there’s a silver lining for the silver-haired set: older people are happier. Also, what longevity means if you’re a tree. Plus, why civilizations need to stick around if we’re to make contact with E.T.

    And, how our perception of time shifts as we age, and other tricks that clocks play on the mind.

  5. Smashing Physics: how we discovered the Higgs boson - podcast | Science | theguardian.com

    This week Guardian science editor Ian Sample meets particle physicist Professor Jonathan Butterworth from University College London to talk about his new book Smashing Physics. It’s an insider’s account of one of the most momentous scientific breakthroughs of our times: the discovery of the Higgs boson announced in July 2012.

    Jon discusses what it’s like to work on the largest science experiment in history and why such ambitious – and costly – endeavours benefit us all.

    Next up, British Association media fellow Nishad Karim reports from the UCL Symposium on the Origins of Life. Be it life on Earth or life elsewhere in the universe, this symposium covered it all with a range of experts from cosmology and biology to meteorology, discussing some very big questions. Where did we come from? Did life begin on Earth or elsewhere? Are we alone?

    Nishad spoke to several of the presenters including Dr Zita Matins, an astrobiologist from Imperial College London, and Dr Dominic Papineau, a geochemist from UCL. Dr Martins is a specialist in finding organic material essential for life in meteorites, and Dr Papineau looks for old organic life a little closer to home, analysing Earth rocks.

    Other speakers included Dr Francisco Diego, a UCL cosmologist, who discussed the life of the universe itself from beginning to now, 13.8bn years later.

    And finally, Ian asks Guardian environment writer Karl Mathiesen whether 2014 will be the hottest year on record.

  6. Craig Venter: Life at the Speed of Light : NPR

    In his new book Life at the Speed of Light: From the Double Helix to the Dawn of Digital Life, Craig Venter writes of the brave new world synthetic biology may some day deliver: from consumer devices that print out the latest flu vaccine to instruments on Mars landers that analyze Martian DNA and teleport it back to Earth to be studied or recreated.

  7. E.O. Wilson: My wish: Build the Encyclopedia of Life

    As E.O. Wilson accepts his 2007 TED Prize, he makes a plea on behalf of all creatures that we learn more about our biosphere — and build a networked encyclopedia of all the world’s knowledge about life.

  8. From the Archives: The Story Behind the ‘World’s Most Famous Atheist’ Richard Dawkins: Forum

    British zoologist Richard Dawkins turned evolutionary theory on its head when he published his book, ‘The Selfish Gene,’ in 1976. His recently released autobiography, ‘An Appetite for Wonder,’ sheds light on the first 35 years of Dawkins’ life, from his birth in Kenya, to his fascination with science at Oxford, to the origin of his gene-centered view about natural selection. He joins us in the studio.

  9. Science Weekly podcast: the origin of life

    Scientist, broadcaster and writer Adam Rutherford discusses his new book Creation which explores the chemical origins of life on Earth, and reveals why he believes our future is in the hands of genetic engineers.

    Alok Jha is joined by Adam Rutherford to discuss how life began some 4bn years ago – and the manipulation of its blueprint, DNA, through genetic engineering. Adam’s latest book, Creation: The Origin of Life/The Future of Life, is two books in one. The first details the latest research into how the first cellular life form emerged, and the second looks at the rapidly developing science of synthetic biology.

  10. Scientists Discover Dung Beetles Use The Milky Way For GPS : NPR

    A team of scientists has discovered that dung beetles climb on dung balls and dance around in circles before taking off. This dance is not one of joy, however —€” the insects are checking out the sky to get their bearings. Melissa Block and Audie Cornish have more.
