Climate change has caused pollen seasons to start sooner and last longer.
Allergic reactions to pollen may occur at different times of the year and for prolonged periods, and this will worsen with climate change.
Pollen counts focus on the amount of grains in the air, but it could be the species that are more important.

Pollen is ancient, but in recent times, it's getting worse. An allergist offers ways to manage the suffering and enjoy the spring.
Both make you sneeze and give you a runny nose.
You can tell the difference by the colour of your snot.

Pollination by commercially raised bees is important to a variety of crops but none more than California almonds. In turn, beekeepers depend on them.
Australian plants leave a unique pollen signature in our honey.
Australia's distinctive native plants give our honey a distinctive stamp. Welcome to melissopalynology: the study of pollen.
Unlocking the genetic code of certain grasses could help allergy sufferers.
The well-being of pollinators like bees have a direct impact on our lives.

Pollination in South Africa's ecosystems is extremely complex. However new advances such as pollen metabarcoding help us understand interactions between pollinators and pollen.
Hay fever sufferers should have access to an asthma puffer every spring, even if they’ve never had asthma symptoms.
What you should be doing this thunderstorm asthma season.
Bees living in cities often have to seek out green space like parks, ravines and gardens. Green roofs could offer them some habitat.
Urban bees deal with what's known as "habitat patches," discontinuous patches of green like gardens, parks and ravines. Green roofs could offer relief to bees dealing with habitat fragmentation.

Bees need pollen to survive and grow, but not all plants can provide the right mix.
After the storm … Researchers are working together to predict future outbreaks of thunderstorm asthma.
Researchers from a range of disciplines need to work together if we are to predict and prepare for the next thunderstorm asthma event.
Why didn’t we learn the lessons from earlier thunderstorm asthma events?
Melbourne's recent thunderstorm asthma event caught services by surprise. So, is it time for a national health protection agency to coordinate our public health response?
Genetic techniques can help make pollen useful for cracking criminal cases.

Pollen is all around us, is extremely durable and can provide clues about where someone's been. A new genetic technique will make it easier to use pollen evidence in criminal investigations.
Sunflowers contain less protein than aloe plants and bees need more of this.
Nutrition is another factor - in addition to pesticides and bee disease - that has led to the dwindling of the global bee population.
Allergies are becoming more frequent in the western world.
Allergies are reactions caused by the immune system as it responds to environmental substances that are usually harmless. But we don't yet have a cure or the ability to prevent them from developing.

The fossilized plant Montsechia relied on water to disseminate its genetic material and may rewrite the book on when and how the first flowering plants evolved.
Hay fever affects one in six Australians.
Ah, spring, the sun shines again, the birds sing and - ach-hoo! Airborne grass pollens trigger bouts of hay fever and episodes of asthma in people with pollen allergies. But there is a way we could mitigate…
