In an era when scientists are increasingly exposed, they need to be careful to distinguish between scientific criticism and personal attacks.

Harvard’s Odyssey unlocks big data

January 26, 2015

Increasingly, big data is changing life’s game board.

As technology evolves and becomes further integrated into society, massive amounts of data are being collected and stored. From the app on your cellphone to the swipe of your credit card to the systems that monitor everyday activities, data is endlessly transmitted and interpreted. With supercomputers within easy reach and storage infinitely scalable, researchers now have the power and resources not just to collect data, but to analyze it and make important discoveries.

Imaging captures how blood stem cells take root

A see-through zebrafish and enhanced imaging provide the first direct glimpse of how blood stem cells take root in the body to generate blood. Reporting online today in the journal Cell, researchers in Boston Children’s Hospital’s Stem Cell Research Program describe a surprisingly dynamic system that offers several clues for improving bone-marrow transplants in patients with cancer, severe immune deficiencies, and blood disorders, and for helping those transplants “take.”

The divergent skull

Chances are, you’d be hard-pressed to name something you have in common with a chicken. Would you believe that one answer is the head on your shoulders?

For more than a century, scientists have attempted to understand how the bones of the skull develop in vertebrate embryos. Most have concluded that a single developmental pattern — first described in chickens — applies to all vertebrates.

A new study conducted by Harvard researchers suggests that this may not be entirely true.
