Depression doesn’t lead to heart disease, as some people suggest, but it’s a sign that you might be at risk of it.
If you're 45 or older and have depression, new research suggests you may need to ask for a heart check when you next see your doctor.
Artificial light has transformed the night sky, a change researchers continue to link to health problems.

Study uses satellite data to add to growing evidence that nighttime light exposure raises risk of breast cancer, with the strongest link among young women.
Australia’s policies on preventing heart disease are based on outdated research from the US.
While we must put in place effective measures to protect against the malicious use of personal data, not using the information collected about Australians comes at a cost.
For the decolonisation of knowledge to be successful, it must be driven by critical thinking.
Phrases like “knowledge production” conceal the fact that knowledge answers to something beyond itself and beyond us. To produce knowledge is to find out about something.
Long-term studies help us prevent the type of diseases that would otherwise land us in hospital.
Long-term studies help identify new risk factors for disease and how we might address them.
The public in Sierra Leone was proactive in reporting suspected Ebola cases.
The power to overcoming Ebola was in public awareness by performing simple yet basic infection prevention and control measures like washing hands, isolation and reporting suspected cases.
Statistics and probability can sometimes yield mind bending results.
Sometimes statistics and probability can produce unexpected or counter-intuitive results. If we're hoping to use numbers to make good decisions, we should be wary of the traps.
A hospital nurse checks the temperature of all visitors in Conakry (Guinea) in 2014, at the height of the Ebola epidemic.
One year after the end of the West African Ebola epidemic, a study of survivors in Guinea shows what has been learned about the deadly virus, and what remains unknown.
What if it wasn’t back to the drawing board every year for a new flu shot?
Flu virus mutates so quickly that one year's vaccine won't work on the next year's common strains. But a new way to create vaccines, called 'rational design,' might pave the way for more lasting solutions.
We propose a different way to look at the factors behind chronic disease, like obesity and diabetes.
A new way of looking at what's behind chronic disease takes into account social, environmental and other factors, rather than blaming individuals.
IQ decline is highest among those who started using during adolescence and among the most persistent (daily) users.
After almost four-and-a half decades and from modest beginnings, the Dunedin study has evolved into one of the most significant long-term tracking studies in the world.
A pickup truck from the Department of Health fumigates in San Juan, Jan. 27, 2016.
It's hard to contain a mosquito-borne infection like Zika when the conditions are ideal for it to spread.
Alcohol use is traditionally higher among men than women but new evidence suggests this is changing.
Women are catching up to men in rates of alcohol consumption and this has important implications for how we think about our community response to harmful alcohol use.
Most cases of Zika are asymptomatic.

A computer model suggests that while more cases of Zika can be expected in the continental U.S. outbreaks will probably be small and are not projected to spread.
What could we do if a real-life zombie disease started to spread?
Patients and companions at the Cholera Treatment Center in Haiti, April 2015.

Unless drinking water and sanitation infrastructure are improved, cholera could remain in Haiti indefinitely.
Observational scientists study subjects in real life, outside a controlled laboratory environment.
The randomised controlled trial is touted as the gold standard in medical research. But its controlled laboratory conditions are far removed from the messy realities of life.
Elementary school students about 13 miles from the Fukushima Daiichi nuclear power plant walk past a geiger counter in 2012.
Remediation will never get radiation to zero in the area affected by the 2011 meltdown at the Fukushima-Daiichi nuclear power plant. Rather than safety, the conversation should focus on acceptable risk.
Even talking to a colleague at an academic conference overseas could have harsh ramifications.
Researchers face stiff fines or even jail time if they inadvertently communicate with foreign colleagues about matters deemed to have a military use.
