It's an exhilarating time for genome-wide association studies
For the past few months it seemed you couldn’t open a journal without reading results of a new genome-wide association study. The results kept pouring in: four studies in April showing seven...

Decades of steady progress in pharmacogenetics have unearthed hundreds of associations between genes and drug response. But the field has to solve some theoretical and practical issues before it can deliver on the promise of personalized drug therapy.
As algorithms go, it’s deceptively simple. Just add together eight weighted pieces of patient information—age, height, weight, race, data about two genes, and a pair of clinical...

There is growing recognition that epigenetics may be just as important as genetics in human health and disease.
In the early 19th century, Jean-Baptiste Lamarck explained evolution as the inheritance of acquired traits; he believed that changes due to behaviors and exposures in one generation could be passed...

The study of HIV evolution is not only critical to fighting the virus; it has also driven advances in the computational tools used to study evolution in general.
When Darwin published On the Origin of Species in 1859, it would be decades before HIV would jump from monkeys to humans and set off a devastating worldwide pandemic. But evolution is at the heart of...

An opportunity and a challenge
When discussing biocomputation startups, there’s one thing people agree on: These days, they don’t generate much excitement among venture capitalists.
“In the 1990s, there...

Epistasis explored
When people work together, some individuals may hinder team performance—essentially masking the abilities of other members—while others may boost the group’s performance beyond the...

Biomarker research, genetics, and imaging are all coming into play
In 1906, at a small medical meeting in Tübingen, Germany, physician Alois Alzheimer gave a now-famous presentation about a puzzling patient. At age 51, Auguste D.’s memory was failing...

HAP-SAMPLE takes real data as the template for simulations
Trying to find the genetic causes of a human disease requires lots of data. These days, researchers scan the genomes of people who do and don’t have a particular disease and look for genome-...

There comes a tipping point in systems-biology studies of gene function where knowing some genes’ functions can, using a computational approach, help hone in on the functions of other genes....

Computation can speed up the time it takes to find new binding partners for old drugs
When cheap drugs are needed fast, researchers and drug companies are increasingly turning to an interesting short-cut: repurposing existing drugs for new uses. Because drugs exert multiple actions in...
