A diamond-based quantum amplifier

In physics, weak microwave signals can be amplified with minimal added noise. For instance, artificial quantum systems based on superconducting circuits can amplify and detect single microwave patterns, although at millikelvin ...

Starvation shown to cause cell remodeling

Body cells burn off fat reserves when nutrient supply from food ceases. A team led by Professor Volker Haucke and Dr. Wonyul Jang from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) has now discovered ...

More flexible than we thought: Worms provide new insights into the evolution and diversification of TGF-beta signaling

The TGF-ß cellular signaling network, essential to various functions in all metazoans and involved in many severe human pathologies like autoimmune diseases and cancer, is more flexible than previously thought.

Photonics chip allows light amplification

The ability to achieve quantum-limited amplification of optical signals contained in optical fibers is arguably among the most important technological advances that are underlying our modern information society. In optical ...

Inflation: How financial speculation is making the global food price crisis worse

UK households, like those in many other countries, are struggling to make ends meet. More than half of households have only £2.66 per week left after paying for bills and essentials, according to figures from the supermarket ...

Unique features of octopus create 'an entirely new way of designing a nervous system'

Octopuses are not much like humans—they are invertebrates with eight arms, and more closely related to clams and snails. Still, they have evolved complex nervous systems with as many neurons as in the brains of dogs, and ...

Guess who? Chimpanzee faces reveal family relationships

Researchers from the University of St Andrews have shown for the first time that not only do wild chimpanzees tend to look like their family members, but also some relationships are easier to detect than others.

Shining a new light on the importance of a critical photosynthesis pathway in plants

Photosynthesis is one of the most important chemical reactions, not just for plants but also for the entire world. The impact and thus the importance of photosynthesis can scarcely be underestimated. Thus, it makes sense ...

Study discovers that mitochondria transmit signals in the immune and nervous systems

Mitochondria are primarily known as the powerhouse of the cell. However, these cellular organelles are required not only for providing energy: Professor Konstanze Winklhofer and her group at the Faculty of Medicine at Ruhr ...

How viruses outwit cellular immune systems

We're used to thinking of the immune system as a separate entity, almost a distinct organ, but the truth is much more complicated. Breakthroughs in recent years—some resulting from research performed in Prof. Rotem Sorek's ...
