Cell receptor has proclivity for T helper 9 cells, airway inflammation
A cell surface molecule, OX40, is a powerful inducer of T helper cells that make copious amounts of interleukin-9.

Smell the potassium
The vomeronasal organ is one of evolution's most direct enforcers.

When the world burned less
In the years after Columbus' voyage, burning of New World forests and fields diminished significantly - a phenomenon some have attributed to decimation of native populations by European diseases.

How to avoid traps in plastic electronics
Plastic electronics hold the promise of cheap, mass-produced devices. But plastic semiconductors have an important flaw: The electronic current is influenced by

Links between magnetic field inversions, mantle concection and tectonis

New discovery of how carbon is stored in the Southern Ocean
A team of British and Australian scientists has discovered how carbon is drawn down from the surface of the Southern Ocean to the deep waters beneath.

New cause of child blindness identified
A team of international scientists in collaboration with the Research Institute of the McGill University Health Centre identified a new gene responsible for Leber Congenital Amaurosis, a devastating genetic form of blindness in newborns.

Massachusetts Eye and Ear researchers discover elusive gene that causes a form of blindness from birth
Researchers from the Massachusetts Eye and Ear Infirmary, the Children's Hospital of Philadelphia, Loyola University Chicago Health Sciences Division and their collaborators have isolated an elusive human gene that causes a common form of Leber congenital amaurosis (LCA), a relatively rare but devastating form of early-onset blindness.

BGI reports the latest finding on NMNAT1 mutations linked to Leber congenital amaurosis
BGI reports the latest finding on NMNAT1 mutations linked to Leber congenital amaurosis.

Giant ice avalanches on Iapetus provide clue to extreme slippage elsewhere in the solar system
Saturn's ice moon Iapetus has more giant landslides than any solar system body other than Mars.

Cutting the graphene cake
Researchers at the University of Manchester have demonstrated that graphene can be used as a building block to create new 3D crystal structures which are not confined by what nature can produce.

Chronic 2000-04 drought, worst in 800 years, may be the 'new normal'
The chronic drought that hit western North America from 2000 to 2004 left dying forests and depleted river basins in its wake and was the strongest in 800 years, scientists have concluded, but they say those conditions will become the

New discovery of how carbon is stored in the Southern Ocean
A team of British and Australian scientists has discovered an important method of how carbon is drawn down from the surface of the Southern Ocean to the deep waters beneath.

Researchers analyze melting glaciers and water resources in Central Asia
As part of the ACQWA European project, coordinated by the Institute of Environmental Sciences at the University of Geneva (UNIGE), researchers from UNIGE collaborated with scientists from the German-speaking part of Switzerland, Germany, and Russia to highlight the recent climate changes and glaciation in the Tien Shan Mountains (Central Asia), and explain their consequences.

Breakthrough by U of T-led research team leads to record efficiency for next-generation solar cells
Researchers from the University of Toronto (U of T) and King Abdullah University of Science & Technology (KAUST) have made a breakthrough in the development of colloidal quantum dot (CQD) films, leading to the most efficient CQD solar cell ever.

Gene discovery set to help with mysterious paralysis of childhood
Alternating hemiplegia of childhood is a very rare disorder that causes paralysis that freezes one side of the body and then the other in devastating bouts that arise at unpredictable intervals.
