A new quantum switch for electronics

A Russian physicist and his international colleagues studied a quantum point contact (QCP) between two conductors with external oscillating fields applied to the contact. They found that, for some types of contacts, an increase ...

A magnetic twist to graphene

Electrons in materials have a property known as 'spin," which is responsible for a variety of properties, the most well-known of which is magnetism. Permanent magnets, like the ones used for refrigerator doors, have all the ...

Preparing for a human mission to Mars

Future human missions to Mars depend on field research in an environment similar to that of Mars. It will enable the evaluation of operational concepts and optimization of strategies. The goals and results of the AMADEE-18 ...

Paper addresses fieldwork safety for minority scientists

Scientists and graduate students with minority identities who conduct fieldwork report being stalked, followed, sexually assaulted, harassed, threatened, having guns pulled on them and police called on them.

Biobased products can produce luminescent textiles

Luminescent textiles can be created by using a bioluminescent reaction system. This is something that Sweta Iyer, with her newly-minted doctorate, has established. Her doctoral thesis in the field of Textile Technology at ...

Could megatesla magnetic fields be realized on Earth?

Magnetic fields are used in various areas of modern physics and engineering, with practical applications ranging from doorbells to maglev trains. Since Nikola Tesla's discoveries in the 19th century, researchers have strived ...

Terahertz zaps alter gene activity in stem cells

Terahertz light pulses change gene expression in stem cells, report researchers from Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS) and Tokai University in Japan in the journal Optics Letters. ...
