Gas rich galaxies confirm prediction of modified gravity theory

(PhysOrg.com) -- Recent data for gas rich galaxies precisely match predictions of a modified theory of gravity know as MOND according to a new analysis by University of Maryland Astronomy Professor Stacy McGaugh. This -- ...

New discovery could enable portable particle accelerators

Conventional particle accelerators are typically big machines that occupy a lot of space. Even at more modest energies, such as that used for cancer therapy and medical imaging, accelerators need large rooms to accommodate ...

'Expansion entropy': A new litmus test for chaos?

Can the flap of a butterfly's wings in Brazil set off a tornado in Texas? This intriguing hypothetical scenario, commonly called "the butterfly effect," has come to embody the popular conception of a chaotic system, in which ...

Unusual interactions between Pluto's moons

Much ink has been spilled over Pluto's reclassification as a dwarf planet. And yet, such discussions have not diminished scientific interest in Earth's most distant cousin. A new study is the first to reveal fascinating details ...

Early Earth had a hazy, methane-filled atmosphere

More than 2.4 billion years ago, Earth's atmosphere was inhospitable, filled with toxic gases that drove wildly fluctuating surface temperatures. Understanding how today's world of mild climates and breathable air took shape ...

Scientists mix the unmixable to create 'shocking' nanoparticles

Making a giant leap in the 'tiny' field of nanoscience, a multi-institutional team of researchers is the first to create nanoscale particles composed of up to eight distinct elements generally known to be immiscible, or incapable ...
