Micromotors deliver oral vaccines

Vaccines have saved millions of lives, but nobody likes getting a shot. That's why scientists are trying to develop oral vaccines for infectious diseases. But to be effective, the vaccine must survive digestion and reach ...

What's next for Siemens and Alstom after merger veto?

After Brussels on Wednesday derailed a planned Siemens-Alstom merger that was meant to create a European rail behemoth, here's a look at what's next for the German and French firms in an industry bracing for fierce Chinese ...

Video: Jupiter odyssey

ESA's Jupiter Icy Moons Explorer, Juice, is set to embark on a seven-year cruise to Jupiter starting May 2022. The mission will investigate the emergence of habitable worlds around gas giants and the Jupiter system as an ...

Novel enzyme discovered in intestinal bacteria

The human intestinal system contains a complex community of microorganisms, the intestinal microbiome, which metabolizes food components that have not readily been digested. However, there are also microbial degradation processes ...

Hydrogels change water and solute dynamics

Hydrogels form tiny, water-filled pores with diameters so small that molecular-level studies can be difficult. Moreover, the motion of water molecules and dissolved ions is so fast that they are difficult to follow. Therefore, ...

Theoretical model may help solve molecular mystery

Spintronics is promising for future low-power electronic devices. Spin is a quantum-mechanical property of electrons that can best be imagined as electrons spinning around their own axes, causing them to behave like small ...

The subtle role of surfaces in ion stickiness

How ions stick to surfaces greatly influences vital processes in everything from water purifiers to batteries. For decades, scientists have debated the mechanics of such binding, or adsorption. Certain ions in water didn't ...
