A young girl is inoculated with typhoid, Texas, 1943.
We've known how to control typhoid for over 100 years. The rapid current increase of drug-resistant variants in both rich and poor countries is down to decades of short-sighted global health policies.
New Zealand’s coastline spans a distance greater than from the south pole to the north pole.
New Zealand has one of the world's largest ocean territories, but the marine environment is at risk from climate change, pollution and fishing.
The unpopular badger cull has had only 'modest' success in reducing bovine TB, according to a recent report. What would an alternative approach that was effective and humane look like?
Museum collections are repositories of specimens and data, including specimens, tissue samples and vocal recordings.

Taxonomists are becoming as rare as some of the species they work on, and this puts museum collections and conservation efforts under threat and increases the risk of biosecurity incursions.
White spot virus is highly infectious, and can kill more than 80% of farmed prawns within days.
It's possible the white spot virus is now endemic in Australia - in other countries where it has broken out, it has never been eradicated.
An adult Halyomorpha.
An invasive insect native to Asia, Halyomorpha halys, has been detected in the US, Canada and southern Europe. It’s now made its debut in Paris.
Australian growers Imported rassicaceae seeds, including radishes, may be required o
A proposal that all imported vegetable seeds be treated with fungicide has drawn outrage from Australia's organic producers, who fear losing their certification.

Where do plague bacteria go between outbreaks? Research demonstrates that they can survive and replicate inside amoebae that are widely present in soil and water worldwide.
Japanese vessel washed ashore on Long Beach, Washington being inspected by John Chapman.
As well as thousands of deaths and huge destruction, Japan's 2011 tsunami carried potentially invasive species _en masse_ across an entire ocean.
Invasive frogs can have a major impact on the environment. Some move continents by human trade or travel. But determining how to control them can lead to policies that limit their spread and effects.
These migratory pied imperial-pigeons in Far North Queensland, like many of Australia’s 22 species of native pigeons and doves, play an important role in our ecosystems but may be at risk from emerging viruses in domestic pigeons.
Two recently emerging viruses in domestic pigeons in Australia may pose a significant threat to Australia's 22 species of native pigeons and doves, many of which have crucial ecosystem roles.
Red-eared sliders were once popular pets but are currently banned in Australia. These turtles are still regularly found in the wild and being kept as illegal pets.
Exotic pets may rank highly on the novelty and excitement scale, but little is known about their ownership in Australia.
When a man was diagnosed with Ebola in Dallas in 2014, workers cleared out the apartment unit where he had been staying.
President Trump wants to slash global health funding at a time when more investment is needed, not less. This spending can protect Americans – as well as foreigners – from deadly diseases.
It’s not always obvious where a new technology will end up.

A scientific breakthrough in a vacuum may be free of ethical implications. But many developments can be used for good or evil, or both. There's a fine balance on what to control and to what extent.
Boa constrictors are frequently found at large in Australia, despite being banned.
Keeping non-native reptiles as pets is against the law – with good reason. Alien species traded on the black market can potentially establish themselves in the wild if they are released or escape.
Some of the many species in the Australian National Insect Collection.
At least 100,000 insects are among the many Australian species still to be formally identified. That's a problem for any biosecurity experts who need to be able to spot potentially invasive bugs.
South Africa needs to ensure that it is equipped to deal with bioterrorism attacks and possible laboratory outbreaks.
In the science world, laboratories are essential but safety precautions should be taken to prevent any incidents like the Ebola outbreak or biochemical attacks.
An historian reading the government White Paper on developing northern Australia will realise we’re actually heading all the way back to the 1890s.
The federal government's recent White Paper on developing northern Australia has disturbing echoes of the 1890s, a time when unbridled capitalism and indentured labour developed the North.

On Human Experiments: what lies behind some of the most shocking human experiments in recent history? Here's a clue: most of it took place during wartime or when war seemed like a real threat.
Honeybees pollinate a third of Australia’s food crops. Losing them due varroa might would cost the economy billions of dollars.
A nationwide outbreak of foot and mouth disease; an invasion of a devastating wheat disease; our honeybees completely wiped out. These are just three possible disastrous scenarios facing Australia; they’re…
