We summarize the week's scientific breakthroughs every Thursday.
- Physics
Protons may waltz off nuclear dance floor
Detection of proton pairs simultaneously emitted from neon nuclei raises the possibility that a new and long-sought window into the nucleus has been found and unlocked.
- Materials Science
Cinching nanotubes into tough fibers
Irradiating bundles of carbon nanotubes can lead to tougher fibers.
- Physics
Radioactive sprinkles keep machines true
Needing tiny radioactive sources to calibrate medical scanners with ever-sharper vision, an Australian team dipped tiny balls the size of candy sprinkles into a radioactive liquid.
- Physics
Bubble Fusion: Once-maligned claim rebounds
Researchers who reported 2 years ago that they created nuclear-fusion reactions inside bubbles imploding in a vat of liquid acetone have now bolstered their controversial claim with new evidence.
- Materials Science
Hard Stuff: Cooked diamonds don’t dent
When exposed to high heat and pressure, single-crystal diamonds become extraordinarily hard.
- Physics
Nuclear pudding—to go
Moving at nearly the speed of light, atomic nuclei hurtling through a huge particle collider may become mostly dense, flattened puddings of nuclear particles known as gluons.
- Physics
New supergas debuts
A cloud of ultracold potassium atoms, manipulated by means of a magnetic field, has coalesced into a new super form of matter called a fermionic condensate.
- Physics
Candy Science: M&Ms pack more tightly than spheres
Squashed or stretched versions of spheres snuggle together more tightly than randomly packed spheres do.
- Physics
Two New Elements Made: Atom smashups yield 113 and 115
Two new elements—115 and 113—have joined the periodic table.
- Materials Science
Light whips platinum into shape
Scientists are exploiting the molecular machinery behind photosynthesis to create unique nanostructures out of platinum.
- Physics
Goo’s melting could keep battery cool
Using the sometimes dangerous heat of lithium batteries to melt wax or similar materials may keep the potent cells cool enough for safe use in electric vehicles while also boosting the batteries' performance.
- Physics
Electron cloud mirrors fossil life-form
Remarkable molecules whose electron clouds would resemble now-extinct marine creatures called trilobites could appear in experiments on ultracold atom clouds known as Bose-Einstein condensates, theorists predict.
