As the world warms up, some species cannot move to cooler climes in time to survive. Camille Parmesan thinks humans should help even if it means creating invasive species
There are fewer fish in the sea than ever. Complexity theory, argues mathematician George Sugihara, provides a counterintuitive way to revitalize the world's fisheries
The ability to spread underlies the killing power of cancer. The process occurs, John Pawelek thinks, when tumor cells fuse with white blood cells—an idea that, if right, could yield new therapies
Shinya Yamanaka discovered how to revert adult cells to an embryonic state. These induced pluripotent stem cells might soon supplant their embryonic cousins in therapeutic promise
A geneticist ordained as a Dominican priest, Francisco J. Ayala sees no conflict between Darwinism and faith. Convincing most of the American public of that remains the challenge
How did self-replicating molecules come to dominate the early Earth? Using the mathematics of evolutionary dynamics, Martin A. Nowak can explain the change from no life to life
Patricia Hunt, who helped to bring the issue to light a decade ago, is still trying to sort it all out
Like many stem cell pioneers, Ian Wilmut, the creator of Dolly the sheep, has jumped to an alternative approach. Is this the beginning of the end for embryonic cloning?
The body and its intestinal flora produce chemicals with hidden health information, Jeremy Nicholson has found. Someday treating disease may mean treating those bacteria
Walter Fiers found a protein segment on the influenza virus that could lead to a universal flu vaccine, which would end seasonal shots and provide pandemic protection
Ten years ago two teams discovered that the universe will expand forever at an ever faster rate, thanks to an unseen energy. The leader of one of the groups, Saul Perlmutter, expects that new observations will soon illuminate the universe's dark side
Using machine learning, Chris Wiggins hopes to develop models that can predict how all of an organism's genes behave under any circumstance - and thereby explain precisely why some cells become sick or cancerous
Is love and marriage with robots an institute you can disparage? Computing pioneer David Levy doesn't think so - he expects people to wed droids by midcentury. Is that a good thing?
Using standard inheritance theory, scientists have searched for the genes underlying autism with little success. Michael Wigler thinks he knows why - and how the disorder persists over generations
Supplement: Working around the Mendelians: A Q&A with Michael Wigler
Our hominid ancestors could never have eaten enough raw food to support our large, calorie-hungry brains, Richard Wrangham claims. The secret to our evolution, he says, is cooking
Sasquatch is just a legend, right? According to the evidence, maybe not, argues Jeffrey Meldrum--a position he holds despite ostracism from his fellow anthropologists and university colleagues
In the 1960s Marshall W. Nirenberg deciphered the genetic code, the combination of the A, T, G and C nucleotides that specify amino acids. So why do people think that Francis Crick did it?

Deadbeat granddads, life-shortening sons and genetically bullying brothers—these are just a few effects revealed in biologist Virpi Lummaa's studies of how evolutionary forces shape later generations
Lene Vestergaard Hau made headlines by slowing light to below highway speed. Now the ringmaster of light can stop it, extinguish it and revive it—and thereby give quantum information a new look
In putting teleportation, entanglement and other quantum oddities to the test, physicist Anton Zeilinger hopes to find out just how unreal quantum reality can get

In a post-9/11 world, where security demands are high, personal privacy does not have to be sacrificed, says computer scientist Latanya Sweeney, who discusses a few ways to save it.
By Chip Walter | Jun 27, 2007
Computer scientist Latanya Sweeney helps to save confidentiality with "anonymizing" programs, "deidentifiers" and other clever algorithms. Whether they are enough, however, is another question

Eric Vilain discusses the biology and politics of mixed-sex individuals, arguing that terms such as "hermaphrodite" and "intersex" are vague and hurtful.
By Sally Lehrman | May 30, 2007
Babies born with mixed sex organs often get immediate surgery. New genetic studies, Eric Vilain says, should force a rethinking about sex assignment and gender identity.

Sydney Possuelo is among the last, and certainly the most famous, of the sertanistas—men who make a living by conducting dangerous first-contact missions with remote indigenous peoples of the Amazon.
