We summarize the week's scientific breakthroughs every Thursday.
- Physics
Bunches of atoms madly morph
While investigating the instability of tiny clusters of atoms, scientists observe ultrasmall salt grains switching shapes at a stupendous rate.
- Physics
New approach smooths wrinkle analysis
A simple new theory of wrinkle formation predicts basic traits of wrinkled surfaces, such as how close together the folds will be, without miring scientists in impossible-to-solve equations.

Making Polymers That Self-Destruct: Layers break apart in controlled way
A new polymer film chews itself apart under certain conditions, making it a potential candidate for the controlled delivery of therapeutic drugs.
- Physics
Device Sees More inside Live Cells
A new type of optical microscope, which can discern objects smaller than a supposedly fundamental limit for visible-light viewing, may make it possible to see finer details of the insides of living cells.
- Physics
A Curie-ous Tale
Marie Curie discovered two elements and won two Nobel Prizes for her pioneering studies on radioactivity. A new online exhibit at the American Institute of Physics’ history site depicts how she displayed her ardor and brilliance in many other facets of life as well, such as organizing and equipping a radiological medicine unit for French […]

Waterproof Coats: Materials repel water with simplicity, style
Researchers have produced new types of water-repelling surfaces, including one that's colorful and another made of inexpensive plastic.
- Materials Science
Technique may yield vocal cord stand-in
A plastic material used in some biological implants could someday form a foundation for tissue that can repair or replace human vocal cords.
- Materials Science
Ceramic rebounds from stressful situations
The ceramic titanium silicon carbide can fully recover after being compressed to a degree that would leave most ceramics shattered and most metals permanently deformed.
- Physics
New equation fits nitrogen to a T
An elaborate, new equation that yields more accurate values for nitrogen's properties might have a multimillion-dollar impact in the cryogenic fluids industry.
- Physics
Gecko toes tap intermolecular bonds
For scurrying upside down on smooth ceilings and other gravity-defying feats, lizards known as geckos may exploit intermolecular forces between the surface and billions of tiny stalks under their toes.
- Physics
Electronic Acrobats: Tidily tweaking electrons’ twirls
The first demonstration of three-dimensional, electrical control of a quantum property of electrons known as spin marks an important step toward a new type of spin-based electronics and, possibly, quantum computers.
- Materials Science
Ancient seal technology shows its age
Modern technologies reveal than an ancient method of engraving tough quartz in Mesopotamia was adopted some 1,500 years later than scholars had thought.
