In January, measles returned to the Pacific Northwest, while Ebola resurged in the Congo. It would take a lot more research for scientists to be able to stop threats like these in their tracks.
Wild boars are being scapegoated for an epidemic of African swine flu that threatens the pork industry.
Scientists still rely on a set of 19th century postulates to identify disease-causing organisms but more than 100 years of research shows why we need to move on.

Reports of demonic possession are once again on the rise. But during the devil’s last apogee in early modern Europe, demonic afflictions were taken seriously by both priests and physicians.
Remotely monitoring honeybee hives can help track the health of the colony.
Remote sensors allowed us to observe the in-hive activities of honeybees, which could be key to keeping bee colonies worldwide healthy.
Lots of positive pregnancy tests this time of year.
Did you ever consider that human beings might have a breeding season? Birth seasonality exists – and has interesting implications for childhood disease outbreaks.
Ebola is a dreadful disease and is one of the deadliest infections known to medical science.
Instability in the DRC and Ebola's deadly properties is making it hard to contain the virus.
Babies to order.
Forecasts of designer babies followed the announcement of the gene-edited twins, just as they have for any reproductive technology since 1978. This signals the public must learn more about genetics.
A study showed it’s social circumstance, and not biology, that explains most of the differences in the occurrence of diabetes among racial and ethnic groups.
What contributes most to being at high risk of diabetes – diet, genes or something else? Big research questions need robust research approaches, so let's break it down.
Staying in school improves your chances of a healthy future.
New data underscore that adults with no high school diploma or GED are at the greatest risk for the leading causes of disease and death.

Fungi perform a vital role in the biological cycle, but pose an increasing danger to human health – invasive fungal infections kill three times more people than malaria.
Faecal bacteria on hands is really common.
Handshakes may be polite, but they're also a sure fire way to transfer lots of bacteria from one hand to another.
The term “epidemic” is now being used for more than infectious diseases. So what does it actually mean?
The obesity epidemic, the flu epidemic, the opioid epidemic... in the 21st century, everything seems to be an "epidemic". But what does the term actually mean?
Many people feel conflicted about the use of animals in scientific research. But what is actually involved?
‘I’m still me inside’.
Comics often portray those with dementia as abnormal or less than human.
There's plenty of evidence that modern swill-feeding would be safe, sustainable, and popular.

New research uses pathology in dinosaur bones to look at predator-prey interactions in the fossil record.
Thelazia gulosa is an eyeworm parasite that infects cows. But an Oregon woman’s discovery of the worms in her own eye has raised concerns about parasites that jump from animals to humans.
A stomach-churning viral video of an Oregon woman who describes removing cattle eyeworms from her eye has renewed interest in parasites that jump from animals to humans. Here's all you need to know.
