astma – ny teknik fjerner årsag til allergisk astma

New technique removes the cause of allergic asthma: Antibodies are suctioned off
Allergies are the most common cause of asthma. The immune system over-reacts to harmless substances such as birch or grass pollen, for example, forming immunoglobulin E antibodies (IgE). Together with the inflammatory cells in the skin and mucous membranes, the "mast cells", IgE antibodies are responsible for certain allergic diseases, such as asthma and hay fever. Scientists have now successfully

kræft – antistoffer kan bremse metastaser

Reprogrammed blood vessels promote cancer spread
Tumor cells use the bloodstream to spread in the body. To reach the blood, they first have to pass the wall of the vessel. Scientists have now identified a trick that the cancer cells use: They activate a cellular signal in the vessel lining cells. This makes the passage easier and promotes metastasis. In experiments with mice, the researchers were able to block this process using antibodies.

The rare bacterial species in a microbial community — species that each make up rarely more than one tenth of one percent of the entire population — play a very important role in ecosystem health and stability, report researchers.

Group blazes path to efficient, eco-friendly deep-ultraviolet LED
A research group has demonstrated the ability to produce deep-ultraviolet emission using an LED light source, potentially solving several problems related to quantum efficiency of current devices.

Revealing Aspergillus diversity for industrial applications
The sequencing the genomes of 10 novel Aspergillus species, which were compared with the eight other sequenced Aspergillus species, has now been announced by researchers. With this first ever genus-wide view, the international consortium found that Aspergillus has a greater genomic and functional diversity than previously understood, broadening the range of potential applications for the fungi con

OLYMPUS experiment sheds light on structure of protons
A mystery concerning the structure of protons is a step closer to being solved. Two photons, not one, are exchanged in electron-proton interactions, a seven-year study indicates.

Boosting the lifetime, effectiveness of biomedical devices
A new approach has been found to boosting the lifetime and effectiveness of electronic biomedical devices. The discovery will help the devices better communicate with neural tissue by improving adhesion.

Researchers remotely control sequence in which 2-D sheets fold into 3-D structures
Inspired by origami, researchers have found a way to remotely control the order in which a two-dimensional (2-D) sheet folds itself into a three-dimensional (3-D) structure. The folds are controlled by manipulating light.

Microbiome diversity is influenced by chance encounters
Chance is an overlooked factor in the wide variation of microbe gut populations between individuals, new research suggests. These microbiome variations, which are also affected by diet and environment, contribute to gastrointestinal disorders such as colitis and Crohn's disease.
