Discovery that oxidative stress from pollen is as important as antigen exposure could lead to new therapies
For a person with allergies or asthma, breathing in pollen can be a very bad thing. Within minutes of inhalation by someone sensitive to their effects, these tiny particles can trigger severe inflammation of the respiratory passages, producing uncontrollable sneezing, coughing, or extreme shortness of breath -- symptoms agonizingly familiar to those who suffer from allergy and asthma attacks.
Scientists have long assumed that they know how pollen produces such debilitating responses. They blame an overreaction by the bodys immune system, set off by proteins known as antigens, which are found on the surface of pollen particles--an inappropriate activation of the normal "antigen-mediated" immune response the body uses to defend itself against viruses and bacteria.

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
