Sensor with 100,000 times Higher Sensitivity could Bolster Thermal Imaging

The graphene bolometer sensor detects electromagnetic radiation by measuring the temperature rise as the photons are absorbed into the sensor. Graphene is a two dimensional, one-atom layer thick material. The researchers achieved a high bolometer sensitivity by incorporating graphene in the microwave antenna.

Better detection of microwave radiation will improve thermal imaging, electronic warfare, radio communications. Army-funded research developed a new microwave radiation sensor with 100,000 times higher sensitivity than currently available commercial sensors. Researchers said better detection of microwave radiation will enable improved thermal imaging, electronic warfare, radio communications and radar.

Researchers published their study in the peer-reviewed journal Nature...

A Cancer Shredder

Krebs bekämpfen, indem eine neu entwickelte Substanz Krebs erregende Aurora-Proteine schreddert: Das ist das Ziel einer neuen Studie von Wissenschaftlern der Unis in Würzburg und Frankfurt. (Image: Dr. Sandy Pernitzsch)

Substance with new mechanism of action found. Researchers have developed a new compound for treating cancer. It destroys a protein that triggers its development.

The villain in this drama has a pretty name: Aurora – Latin for dawn. In the world of biochemistry, however, Aurora (more precisely: Aurora-A kinase) stands for a protein that causes extensive damage. There, it has been known for a long time that Aurora often causes cancer. It triggers the development of leukemias and many pediatric cancers, such as neuroblastomas.

Researchers at the universities of Wür...

Geoscience: Cosmic Diamonds formed during Gigantic Planetary Collisions

Geoscientists have found the largest extraterrestrial diamonds ever discovered – a few tenths of a millimeter in size nevertheless – inside meteorites. Together with an international team of researchers, they have now been able to prove that these diamonds formed in the early period of our solar system when minor planets collided together or with large asteroids. These new data disprove the theory that they originated deep inside planets – similar to diamonds formed on Earth – at least the size of Mercury.

It is estimated that over 10 million asteroids are circling the Earth in the asteroid belt...

Quantum Entanglement realized between Distant Large Objects

Quantum entanglement realized between distant large objects
Light propagates through the atomic cloud shown in the center and then falls onto the SiN membrane shown on the left. As a result of interaction with light the precession of atomic spins and vibration of the membrane become quantum correlated. This is the essence of entanglement between the atoms and the membrane.

A team of researchers at the Niels Bohr Institute, University of Copenhagen, have succeeded in entangling two very different quantum objects. The result has several potential applications in ultra-precise sensing and quantum communication and is now published in Nature Physics.

Entanglement is the basis for quantum communication and quantum sensing...
