Discovery of How to Limit Asthma Attack Damage could Stop Disease

Scientists at King’s College London have discovered a new cause for asthma that sparks hope for treatment that could prevent the life-threatening disease.

Most current asthma treatments stem from the idea that it is an inflammatory disease. Yet, the life-threatening feature of asthma is the attack or the constriction of airways, making breathing difficult. The new study, published in Science, shows for the first time that many features of an asthma attack—inflammation, mucus secretion, and damage to the airway barrier that prevents infections—result from this mechanical constriction in a mouse model.

The findings suggest that blocking a process that normally causes epithelial cell death could prevent the damage, inflammation, and mucus that result from an asthma attack.

An international team in Japan is getting ready to power up a 50,000-ton neutrino detector by adding a single metal, which will turn it into the world’s first detector capable of analysing exploding stars beyond the immediate neighbourhood of the Milky Way. Neutrinos are relics from supernovae,. They are so tiny and interact so weakly that every second, trillions of them manage to pass through human bodies without anyone noticing. Studying them can reveal details about how stars in the universe, like our sun, work.

The problem is that all supernova neutri...

Ultrafast Uncoupled Magnetism in Atoms: new step towards Computers of the Future

Couplings of the gadolinium spin system.

Couplings of the gadolinium spin system. (a) The interaction of the different heat baths in an extended three-temperature model. After infrared laser excitation of the valence electrons, the whole system equilibrates by exchanging energy and momentum, indicated by the double arrows. The 5d and 4f spin systems couple via inter- and intra-atomic exchange, where the intra-atomic exchange Jint=130 meV is much larger than the largest (nearest neighbour) inter-atomic exchange Jij=5.9 meV. In thermal equilibrium, the combination of inter- and intra-atomic exchange interactions mediates spin order in the 4f system via the delocalized 5d valence bands...
