Sea lions, otters and birds were some of the many wildlife species that were hit hard by the 1989 Exxon Valdez oil spill in Alaska. Oil spills like these expose the wildlife to new contaminants and can be fatal.

ToxChips study the changes in the DNA of animals exposed to contaminants, like those found in oil spills.
Using 3-D facial images researchers have identified changes in the DNA that contribute to variation in facial features.

Like it or not, the facial feature most influenced by your genes is your nose. Researchers investigate which genes are involved in sculpting the face.
Biological factors shape sexual preference.
A new study of nearly 500,000 individuals finds that many genes affect same-sex behavior, including newly identified candidates that may regulate smell and sex hormones.
The tomatoes we eat have been carefully bred over generations, but now we can tap into wild varieties.
Gene editing of wild plants can help us tap into new sources of food. But we need to make sure it’s safe – and that demands some careful regulation.
DNA evidence tracks the ancient history of the Jewish people.
The genome is becoming the unit of currency for all kinds of genetic testing.
Do you own your own genetic data? The future of genomic databases is almost here, and now is the time to figure out how we are going to allow this information to be used.
Taking the deadly bit out of mosquitoes.

It’s possible to alter the make-up of a species such as a mosquito’s ability to pass on the deadly malaria parasite. But we need to consider the pros and cons of such gene editing technology.
Time to get up.

Gaining a better sense of what genes are involved in regulating circadian clocks could put us on a path to find better treatments and therapies to help people adjust to time shifts.
Scientists have uncovered the genetics that explain the snake’s impressive length – and used the science to create extra-long mice.
New genetic technology could change the DNA of entire species to prevent them from spreading diseases.
To whom is she more closely related?
How many times do people make the comment about which parent a child takes after. So what does genetics say?
Scientists have discovered that a single gene may reveal a weakness in the development of schizophrenia that could help doctors prevent the condition.
