How multiple star systems evolve

Sirius is not a single star at all, but a binary system of two stars. Polaris, the north star, is actually a system of three stars. And Castor, in the constellation of Gemini, actually consists of a whopping six stars. Current ...

New equation bolsters multiphase modeling code

While designing models for the Multiphase Flow with Interphase Exchanges (MFiX) code, one of the National Energy Technology Laboratory's most robust computational tools, Physical Research Scientist Jordan Musser realized ...

Plastics treaty must tackle problem at source, researchers say

The new Global Plastics Treaty must tackle the problem at the source, researchers say. An international negotiation meeting (INC-3) in Kenya begins on Monday, aiming to further develop a legally binding treaty on plastic ...

CubeSat propulsion technologies are taking off

CubeSats are becoming ever more popular, with about 2,400 total launched so far. However, the small size limits their options for fundamental space exploration technologies, including propulsion. They become even more critical ...

Stopping listeria reproduction 'in its tracks'

Listeria contaminations can send food processing facilities into full crisis mode with mass product recalls, federal warnings and even hospitalization or death for people who consume the contaminated products. Destroying ...

Researchers find key to keeping cells in shape

(PhysOrg.com) -- Yale University researchers have discovered how a protein within most cell membranes helps maintain normal cell size, a breakthrough in basic biology that has implications for a variety of diseases such as ...

Polar bears ill from accumulated environmental toxins

New doctoral thesis documents that industrial chemicals are transported from the industrialized world to the Arctic via air and sea currents. Here, the cocktail of environmental toxins is absorbed by the sea's food chains ...

Changing the handedness of molecules

Researchers at Kanazawa University report in Proceedings of the National Academy of Sciences a responsive molecular system that, through chemical reactions, inverses its chirality before becoming racemic.

Interactive size control of catalyst nanoparticles

How many nanometers should catalyst nanoparticles be to optimize the course of the reaction? Researchers usually look for the answer through laborious, repetitive tests. At the Institute of Physical Chemistry of the Polish ...
