Pollen proves beneficial for northern lakes
Mention the word pollen to most people and it triggers thoughts of their battle against allergic reactions. However, a University of Alberta researcher has found an important spin-off for this fine yellow dust-like powder.   view more (2006-06-13)

Summer without the sneezes
Plants lacking allergenic proteins could mean an easier life for hay fever sufferers. Nearly 15% of the UK population suffer an annual battle with this distressing condition - starting in early spring. Forced to take steroids and immunosuppressants to battle the symptoms, most sufferers would jump... view more (2002-02-01)

Asthma epidemics linked to airflow patterns in thunderstorms
It's the airflow patterns in thunderstorms, rather than the electrical activity, thunder, or rain, which trigger asthma epidemics, concludes research in Thorax. The hospital admission rates for asthma and airflow patterns during thunderstorms up to 80 km away were studied for six towns in south... view more (2001-05-16)

A gas, Viagra and sex in plants - researchers at the Instituto Gulbenkian de Ci'™ncia have found a link
Viagra affects growth of the male sex organ of plants, by intensifying the effect of nitric oxide during plant fertilization. This discovery, made by the Plant Development team at the Instituto Gulbenkian de Ci'™ncia(IGC), in Portugal, will be published in Development, in June. The study, led... view more (2004-05-11)

Sexual frustration: programmed cell death prevents plant inbreeding
Scientists have demonstrated the importance of programmed cell death in preventing inbreeding in plants, according to research published in Nature today. Researchers at the University of Birmingham School of Biosciences have found that self-incompatibility, an important mechanism in plants that... view more (2004-05-19)

How to share a bat
New research shows how different species of plants evolve unique floral adaptations in order to transfer pollen on different regions of bats' bodies, thus allowing multiple plant species to share bats as pollinators.   view more (2007-08-23)

Common European Plant Pollens Trigger Asthma Emergencies
High levels of airborne grass pollens trigger surges in severe asthma attacks that require emergency admission to hospital, suggests research published in Thorax. The research was carried out between 1995 and 1998 in the Spanish city of Madrid, which has high levels of different types of airborne... view more (2003-07-25)

Can we keep the cap on transgene escape?
Molecular strategies are being developed to impede the escape of transgenes from transgenic crops into wild relatives, which might become invasive upon acquiring transgenic traits such as resistance to pests or herbicides. For example, to impede escape through pollen, a transgene could be inserted... view more (2004-02-24)

Climate change following collapse of the Maya empire
Researchers from the University of Amsterdam have demonstrated that the climate in South Mexico changed following the collapse of the Maya empire. From preserved pollen grains the paleoecologists could deduce that the climate quickly became dryer. The climate becoming dryer, explains the decrease... view more (2002-01-29)

Stratified seawater disrupts the transport of imposex substances
Researchers from the University of Amsterdam have demonstrated that the climate in South Mexico changed following the collapse of the Maya empire. From preserved pollen grains the paleoecologists could deduce that the climate quickly became dryer. The climate becoming dryer, explains the decrease... view more (2002-01-24)

UT Knoxville professor finds unexpected key to flowering plants' diversity
What began with an off-the-cuff curiosity eventually led Joe Williams to hang from the limbs of a tree 80 feet above the soil of northeastern Australia.   view more (2008-07-29)

Female Plant 'Communicates' Rejection or Acceptance of Male
Without eyes or ears, plants must rely on the interaction of molecules to determine appropriate mating partners and avoid inbreeding.   view more (2008-10-24)

Will buffer zones stop genes spreading to nearby crops?
EMBARGOED UNTIL WEDNESDAY 14 APRIL 1999 19:00 BST   view more (1999-04-14)

Hayfever hope
With the peak grass pollen season approaching, scientists can reveal that a daily dose of probiotic can change the immune status of people with hay fever.   view more (2008-06-03)

Rutgers: GM/GMO/Biotech crop containment strategy
Plant geneticists at Rutgers, The State University of New Jersey, may have solved one of the fundamental problems in genetically engineered or modified (GM or GMO) crop agriculture: genes leaking into the environment.   view more (2007-06-07)

Traffic exhaust can cause asthma, allergies and impaired respiratory function in children
Children exposed to high levels of air pollution during their first year of life run a greater risk of developing asthma, pollen allergies, and impaired respiratory function.   view more (2008-04-10)

GENE TRANSFER FROM GENETICALLY MODIFIED CROPS
The report, which is based on a desk study of a substantial quantity of previously published research in related areas, considers all the routes by which the mixing of organic and genetically modified crops may occur, including pollen transfer and the growth of volunteers. It concludes that no... view more (1999-06-17)

Triggers for conservation in Australian biodiversity hotspot
In a treasure hunt through Western Australia's south-west more than 20 new species of trigger plants have been discovered - small plants that catapult pollen onto visiting insects.   view more (2004-09-10)

Study shows genetically engineered corn could affect aquatic ecosystems
A study by an Indiana University environmental science professor and several colleagues suggests a widely planted variety of genetically engineered corn has the potential to harm aquatic ecosystems. The study is being published online this week by the journal Proceedings of the National Academies... view more (2007-10-09)

Simulating kernel production influences maize model accuracy
Recently, researchers at Iowa State University discovered a way to increase the accuracy of a popular crop model. By zeroing in on early stages leading up to kernel formation, scientists believe they can help improve yield predictions across a variety of environmental conditions.   view more (2007-09-24)

Human activity destroys species that the Ice Age could not
Forest clearance and animal overgrazing in the last 5,000 years have destroyed important tree species that had survived even the Ice Age. Dr Mick Frogley, Lecturer in Physical Geography at the University of Sussex, is one of a British research team exploring a site near Lake Ioannina in the Pindus... view more (2002-09-20)

Real Threats To Countryside Ignored In GM Furore, Ecologists Warn
*PLEASE NOTE THIS IS EMBARGOED UNTIL 16 OCTOBER* The UK should be cautious in developing GM technology in agriculture, the British Ecological Society (BES) has said. However, scientists, policy makers and environmental campaigners should beware that by focussing solely on GM crops, the real threats... view more (2003-10-15)

Hotter is better for removing allergens in laundry
A new study finds that the heat setting you choose when doing laundry makes all the difference when it comes to killing dust mites.   view more (2007-05-21)

500,000 years of climate history stored year by year
The bottom of Turkey's Lake Van is covered by a layer of mud several hundreds of metres deep. For climatologists this unprepossessing slime is worth its weight in gold: summer by summer pollen has been deposited from times long past.   view more (2007-03-15)

Smithsonian scientists connect climate change, origins of agriculture in Mexico
New charcoal and plant microfossil evidence from Mexico's Central Balsas valley links a pivotal cultural shift, crop domestication in the New World, to local and regional environmental history.   view more (2007-06-04)
