Quantum-enhanced sensors for real-life applications

Quantum-enhanced sensors could find their way into applications ranging from biomedical to chemical detection. In a new study, researchers demonstrate the ability of quantum states of light to enhance the sensitivities of state-of-the-art plasmonic sensors. The team presents the first implementation of a sensor with sensitivities considered state-of-the-art and shows how quantum-enhanced sensing can find its way into real-life applications.

NASA Announces New Director of Johnson Space Center

NASA Administrator Jim Bridenstine announced Monday the selection of Mark Geyer as the next director of the agency’s Johnson Space Center in Houston.

World's fastest water heater -- 100,000 degrees in 0.000 000 000 000 075 seconds

Scientists have turned a powerful X-ray laser into the world's fastest water heater, reaching 100,000 degrees Celsius in less than a tenth of a picosecond (millionth of a millionth of a second). The experiment produced an exotic state of water, from which researchers hope to learn more about the peculiar characteristics of Earth's most important liquid.

High-sensitivity microsensors on the horizon

A new article explains how scientists borrowed concepts from quantum mechanics to build new microsensors that can enable data gathering from hard-to-monitor environments.

Deeper understanding of quantum chaos may be the key to quantum computers

New research gives insight into a recent experiment that was able to manipulate an unprecedented number of atoms through a quantum simulator. This new theory could provide another step on the path to creating the elusive quantum computers.

How bacteria guide electron flow for efficient energy generation

Biochemists have isolated a protein supercomplex from a bacterial membrane that, like a battery, generates a voltage across the bacterial membrane. The voltage is used to make ATP, a key energy currency of life. The new findings will inform future efforts to obtain the atomic structures of large membrane protein supercomplexes.

Old Data Reveal New Evidence of Europa Plumes

Scientists re-examining data from an old mission bring new insights to the tantalizing question of whether Jupiter’s moon Europa has the ingredients to support life.

Frequency-stable laser systems for space

For the first time a frequency reference based on molecular iodine was successfully demonstrated in space! What sounds a bit like science fiction is an important step towards laser interferometric distance measurements between satellites as well as for future global navigation satellite systems based on optical technologies. The frequency reference tests were carried out on May 13 on board the sounding rocket TEXUS54.

A micro-thermometer to record tiny temperature changes

Scientists have developed a micrometer-wide thermometer that is sensitive to heat generated by optical and electron beams, and can measure small and rapid temperature changes in real time. This new device can be used to explore heat transport on the micro- and nano-scales, and in optical microscopy and synchrotron radiation experiments.

Shedding light on a cyclic molecule with a twist

As suggested by their name, Möbius molecules have a twisted loop structure, a special characteristic with many potential applications. A Japanese research team has revealed the properties of a type of Möbius aromatic molecule that expresses magnetism and retains high energy levels when exposed to light. These characteristics could potentially be applied in organic solar batteries, lights, and conductive materials.
