NASA Provides Coverage for First Meeting of the National Space Council

NASA Television and the agency’s website will provide live coverage of the first meeting of the National Space Council starting at 10 a.m. EDT Thursday, Oct. 5.

Light-activated nanoparticles can supercharge current antibiotics

Light-activated nanoparticles, also known as quantum dots, can provide a crucial boost in effectiveness for antibiotic treatments used to combat drug-resistant superbugs such as E. coli and Salmonella, new research shows.

A new way to produce clean hydrogen fuel from water using sunlight

Researchers combined graphitic carbon nitride and black phosphorous to make a new metal-free composite photocatalyst capable of producing hydrogen from water. The photocatalyst featured good photocatalytic production of hydrogen, even when powered by low-energy near infrared light.

Nanoscale islands dot light-driven catalyst

Scientists have combined aluminum nanoparticles and smaller metal particles to create a versatile nanostructure that could lead to new applications for plasmonics. The technique allows for customizable surface chemistry and reactivity in one material.

Tungsten offers nano-interconnects a path of least resistance

As microchips become smaller, the shrinking size of their copper interconnects leads to increased electrical resistivity at the nanoscale. Finding a solution to this technical bottleneck is a problem for the semiconductor industry; one possibility involves reducing the resistivity size effect by altering the crystalline orientation of interconnect materials. Researchers conducted electron transport measurements in epitaxial single-crystal layers of tungsten as one potential solution.

Nobel Prize in Chemistry 2017: Cryo-electron microscopy

The Nobel Prize in Chemistry 2017 goes to Jacques Dubochet, Joachim Frank, and Richard Henderson "for developing cryo-electron microscopy for the high-resolution structure determination of biomolecules in solution."

Nuclear magnetic resonance: high sensitivity on smallest space

In many areas from materials sciences to medicine, nuclear magnetic resonance (NMR) is used for detailed molecule-specific investigations. Scientists of Karlsruhe Institute of Technology (KIT) have now succeeded in enhancing the sensitivity of NMR measurements. For this purpose, the scientists used so-called Lenz lenses that focus magnetic flux. The scientists present their method in the journal PLOS ONE.

Electron behaviour under extreme conditions described for the first time

Researchers have modelled the actions of electrons under extreme temperatures and densities, such as those found within planets and stars.

Explainer: Why gravitational wave researchers won a Nobel

Three U.S.-based astrophysicists won the Nobel prize in physics Tuesday for their discovery of gravitational waves, a phenomenon Albert Einstein predicted a century ago in his theory of general relativity. Here's what their discovery means and why they won the prize worth $1.1 million (9 million kronor).

Next International Space Station Crew Available for News Conference, Interviews

NASA astronaut Scott Tingle and crewmates Anton Shkaplerov of the Russian space agency Roscosmos and Norishege Kanai of the Japan Aerospace Exploration Agency (JAXA) will discuss their upcoming mission to the International Space Station in a news conference at 2 p.m. EDT on Wednesday, Oct. 11 at NASA’s Johnson Space Center in Houston.
