Miniaturized laboratory equipment is making it easier to identify airborne pathogens in the field, but there's still work ahead to be able to instantly determine if a room is safe or contaminated.
New Chrysaora from the coast of South Africa.
Global long-term data simply doesn't exist for jellyfish, so scientists struggle to predict, track and mitigate their potential effects.
The polymerase chain reaction, or PCR, is used to copy strands of DNA.
COVID-19 tests rely on a process developed at a biotech company co-founded by a Canadian. Canada’s current testing expertise needs to be channelled to prepare for the next wave, and the next pandemic.

Franklin was born a century ago, and her X-ray crystallography work crucially contributed to determining the structure of DNA.
The neighbourhood a child grows up in may influence their health for years to come by changing the activity of their genes.

This decades-long study found that living in poorer communities changes how genes are regulated.
Specimens like these at Dublin’s Natural History Museum contain valuable information about the evolution of pathogens and host organisms.
Genetic information that could help finger the next infectious threat is stored in museums around the world.
A coronavirus vaccine is coming, but when?

Vaccine development is usually a long process. The coronavirus pandemic is forcing researchers to innovate and test potential vaccines faster than ever before.
If we are not careful, the coronavirus pandemic could lead to a rise in xenophobic attitudes.
It seems as though every other day we're told a cure has been found for coronavirus. This is not strictly true – but there are some therapeutic options showing promise.
There are many ways to make a vaccine. In a time of crisis, the more paths towards success the better.

Under pressure to develop a coronavirus vaccine, researchers have turned to protein synthesis, genetics and hybrid viruses. It is likely a mix of these approaches will be used to fight the coronavirus.
The origin of the Covid-19 virus is still unclear: a cave, the forest…
The SARS-CoV-2 virus responsible for the COVID-19 pandemic is undergoing extensive genetic analysis around the world to understand its origin and evolution.
It might protect thousands of people.
The U.S. has been scrambling to get testing for the coronavirus up to speed.

A molecular biologist explains who should get tested, how the tests work and what the US government is doing to make tests available during a rapidly changing crisis.
Hypacrosaurus skeleton at the Royal Tyrrell Museum, Alberta.
Scientists claim to have found DNA in fossilised dinosaur cartilage.
Almost every genetic database shares information with the pharmaceutical industry but it wasn’t until law enforcement started using the databases that consumers took note.
Privacy concerns that emerged since law enforcement started mining the databases have put such a serious dent in the business that both Ancestry.com and 23andMe have reduced employees significantly.
Epigenetic clocks are a fascinating new technology, but some potential applications are controversial.
Pediatric epigenetic clocks have the potential to accurately assess biological age. However, possible applications in law enforcement and immigration raise ethical issues.
Early proponents of genome sequencing made misleading predictions about its potential in medicine.
Genome sequencing technologies have transformed biological research in many ways, but have had a much smaller effect on the treatment of common diseases.
No one knows exactly how AI-based DNA analysis software works, so it can't be scrutinised in court.
Mosses are among the closest living relatives to Earth’s first land plants.
New research has pinpointed the genetic boost behind one of the biggest transformations of life on Earth.
Direct-to-consumer genetic tests are not an accurate source of health information. Users should also consider the future privacy implications of sharing their genetic data.
DNA testing kits will be a popular gift this holiday season. Before mailing off your saliva, it’s important to understand what these kits can and cannot tell us.
