North Atlantic haddock use magnetic compass to guide them

A new study found that the larvae of haddock, a commercially important type of cod, have a magnetic compass to find their way at sea. The findings showed that haddock larvae orient toward the northwest using Earth's magnetic ...

Scientists create fully electronic 2-D spin transistors

Physicists from the University of Groningen constructed a two-dimensional spin transistor, in which spin currents were generated by an electric current through graphene. A monolayer of a transition metal dichalcogenide (TMD) ...

A matter of concentration

Plants can grow whole new organs with the help of pluripotent stem cells throughout their entire lives. When necessary, these stem cells can develop into any type of cell within an organism. The biologist Prof. Dr. Thomas ...

A reusable catalyst for the synthesis of esters

A chemist from RUDN University has developed a tin silicate catalyst for the production of esters—flavourings, plasticisers, and biofuel components. Unlike existing catalysts, the new material can be made active again and ...

Bat influenza viruses possess an unexpected genetic plasticity

Bat-borne influenza viruses enter host cells by utilizing surface exposed MHC-II molecules of various species, including humans. Now, an international research team from Germany (Medical Center—University of Freiburg and ...

Programmable swarmbots help make flexible biological tools

Biomedical engineers at Duke University have developed a new platform to create biologic drugs using specially engineered bacteria that burst and release useful proteins when they sense that their capsule is becoming too ...

A safer way for police to test drug evidence

Scientists have demonstrated a way for police to quickly and safely test whether a baggie or other package contains illegal drugs without having to handle any suspicious contents directly. The new technique can limit the ...

NASA-NOAA satellite catches Hurricane Kiko at night

Hurricane Kiko continued to track west through the Eastern Pacific Ocean when NASA-NOAA's Suomi NPP satellite passed overhead and provided a view of the storm. Satellite imagery revealed an elongated shape, which indicated ...
