Researchers had suspected that chemical hair relaxers might be behind racial disparities in breast cancer diagnoses. A new study narrows in on lye as a possible cause for that link.
Environmentally dangerous dumps, landfills and pulp and paper mills are more likely to be sited in African Nova Scotian and Mi'kmaw communities. These communities suffer from high rates of cancer and respiratory illness.

Black residents of Shelburne, N.S., spent decades living near a dump, worrying about its possible connection to elevated cancer rates. A new study will investigate the dump’s long-term consequences.
Even when we immunise all Australians who want to be protected against COVID-19, we’re unlikely to achieve herd immunity through vaccination alone. We need three other measures to open our borders.
The emergence of variants of concern in late 2020 marked a shift in the COVID-19 pandemic.

The government says hotel quarantine is ‘serving Australia very well’. But if you look at the leaks as a proportion of COVID-positive returnees, it’s a different story.
Sustained surveillance for disease outbreaks at global hot spots may be the key to preventing the next pandemic.

A more coordinated effort by scientists, stakeholders and community members will be required to stop the next deadly virus that’s already circulating in our midst.
You only have to prevent one case, which could have otherwise led to community spread and lockdown, for such a scheme to pay for itself many times over.
The amount of risk from overseas arrivals depends not just on Australia’s vaccination rates, but also on the particular circumstances of the country from which people are travelling.
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.

The pandemic will not end for anyone, anywhere until it is controlled in every country. Tanzania’s approach will make it that much harder for normality to return.
It could easily be another 12 months until Australians are fully vaccinated. While we’ve had great success fending off the coronavirus, our leaders need to work even more closely to prevail this year.
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.
If you’ve tested positive for COVID-19, a public health officer will call you to interview you. It can be confronting – but it’s important to answer the contact tracer’s questions as best you can.
There’s valuable data on the spread of COVID-19 in this wastewater.

As the world waits for vaccines against COVID-19, testing wastewater can give communities and smaller locales, such as school districts, valuable signals about infections trends.
What will happens when students return home for Christmas?

If nothing is done to reduce university-based Covid-19 infections, each infected student is likely to infect one other person in their household during the winter holidays.
People wear face masks to help control the spread of COVID-19 as they walk along a street in Montréal on Oct. 18, 2020.

The Great Barrington Declaration’s advocacy for naturally acquired herd immunity to COVID-19 amounts to a global chickenpox party: naive and dangerous.
The COVID-19 new normal might be here for quite some time.

As ready as you are to be done with COVID-19, it’s not going anywhere soon. A historian of disease describes how once a pathogen emerges, it’s usually here to stay.
