Sequencing the genetic code of virus samples taken from COVID-19 patients reveals how SARS-CoV-2 is spreading and changing.
The US lags in testing coronavirus samples from COVID-19 patients, which can help track the spread of the virus and the emergence of new variants. But labs are ramping up this crucial surveillance.
Efforts are underway to curb the outbreak.

The virus is always present in nature and when circumstances allow, it may jump from one species to another.
Ten years ago, we feared Tasmanian devils would be wiped out by a bizarre infectious facial cancer transmitted by biting. But new genetic analysis shows they are evolving to live with the disease.
Direct-to-consumer genetic testing can help scientific researchers.
Scientists who work in local companies have acquired local knowledge and are therefore able to work with South Africa's unique genetic diversity better than anyone else.
New DNA analysis revealed that Calvin Hoover killed Christine Jessop in 1984. Toronto Police Chief James Ramer sits next to a screen displaying photos of Calvin Hoover during a news conference on Oct. 15, 2020.

Christine Jessop was murdered in 1984 and, 36 years later, DNA evidence finally identified her killer. But the police investigation's use of genetic genealogical databases raised questions about privacy.
Pulverized ancient bone can provide DNA to scientists for analysis.

By studying the DNA of people who lived in East Asia thousands of years ago, scientists are starting to untangle how the region was populated.
Genetic analysis of virus samples from New Zealand's latest COVID-19 cases is now much swifter. It's providing key information, but hasn't yet answered the question of where this second wave started.

Vaccine development usually spans a number of decades. This is because there's a need to understand the mechanisms of protection against the pathogen, and to minimise adverse reactions.
Genomic sequencing can help in understanding viruses.
The variation captured in these genomes, when compared to genomes sampled elsewhere, provides a fingerprint that might be associated with a particular virus and a particular cluster of transmission.
New research shows animal evolution often involves losing genes and becoming less complex.

A landmark analysis of the genetic sequences of hundreds of different cancers offers crucial insights into the origins and growth of the disease's myriad forms.
Tomatoes’ ancestors looked very different.

Through genetic detective work, scientists have identified missing links in the tomato’s evolution from a wild blueberry-sized fruit in South America to the larger modern tomato of today.
Legislation as well as academic research governance bodies have failed to safeguard the rights of participants from Africa in genomics research.
A genetic “clock” lets scientists estimate how long extinct creatures lived. Wooly mammoths could expect around 60 years.
Knowing an animal's normal lifespan is hugely important for conservation efforts, but it's harder to find out than you'd think.
No, a DNA swab can’t tell you if you’re gay, or likely to be obese, or depressed. And it can be damaging to believe so.
Genetic apps claim to reveal fundamental insights about your health, well-being, and even intellect. But it's not just spurious science - believing these traits are genetic can have harmful consequences.
A viral invasion is revealing how the genome has its own immune system to fight off attacks.

Koala retrovirus is a menace to koalas, but by watching it at work scientists are finding out how the genome defends itself
Outside Earth’s protective atmosphere, there is nothing to shield astronauts from the dangerous cosmic radiation of space.
Space missions are dangerous. But when it comes to long missions, radiation may be the greatest threat to astronauts' health.
Are space twin Scott and Earth twin Mark no longer identical?
Before sending humans to Mars or the moon, scientists need to understand what long-term space living does to the human body. Now results are coming in from the Kelly brothers in the TWINS Study,
With the right skills and infrastructure, Africa can boost its genomics research efforts.
Genomics research is crucial to identify Africa-specific solutions to a range of diseases.
Of more than 500 species of sharks in the world’s oceans, scientists have only sequenced a handful of genomes – most recently, white sharks.
Why do scientists spend so much time and money mapping the DNA of species like white sharks? Single studies may offer insights, but the real payoff comes in comparing many species to each other.
