Full development of the sense of smell in mammals is dependent on functional activity during critical periods in development, according to a study by researchers at Yale, Rockefeller and Columbia Universities and published in the journal, Science.
In mammals, the connection between odor and the brain occurs over a single nerve connection. The olfactory sensory neurons (OSNs) that have the same odorant receptor (OR) are directed to regions of the olfactory bulb, where they coalesce into a single structure, a glomerulus. This process is molecularly determined, but it remains controversial to what extent the process also relies on stimulation from the outside.
The visual system, it is known, develops initially without any functional activity, but is later refined and polished through sensory activity. Charles Greer, professor of neurosurgery at Yale, and his collaborators. examined the postnatal formation of glomeruli in odor receptors M71 and M72 in gene-targeted mice during development to determine whether the same development process is found in the olfactory system.

Flexible, organic and printed electronics conquer everyday life. The forecasts for growth promise increasing markets and opportunities for the industry. In Europe, top institutions and companies are engaged in research and further development of these technologies for tomorrow's markets and applications. However, access by SMEs is difficult. The European project SmartEEs - Smart Emerging Electronics Servicing works on the establishment of a European innovation network, which supports both the access to competences as well as the support of the enterprises with the assumption of innovations and the progress up to the commercialization.
It surrounds us and almost unconsciously accompanies us through everyday life - printed electronics. It starts with smart labels or RFID tags in clothing, we...
The human eye is particularly sensitive to green, but less sensitive to blue and red. Chemists led by Hubert Huppertz at the University of Innsbruck have now developed a new red phosphor whose light is well perceived by the eye. This increases the light yield of white LEDs by around one sixth, which can significantly improve the energy efficiency of lighting systems.
Light emitting diodes or LEDs are only able to produce light of a certain colour. However, white light can be created using different colour mixing processes.
Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.
Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.
Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
