The researchers dissolved polymers and nanoparticles in water, and comingled them at room temperature to solidify a Jello-like substance that - unlike its kitchen counterpart -- did not liquify at higher heat, such as in the body. The technique kept in balance two thermodynamic concepts- enthalpy, which measures energy added to or subtracted from a material, and entropy, which describes how energy changes make a material more or less orderly at the molecular level.

New tools and methods have been described by researchers to study an unusual protein modification and gain fresh insights into its roles in human health and disease. The study - about how certain sugars modify proteins -- lays a foundation for better understanding diseases like muscular dystrophy and cancer.

Researchers conducted a first-of-its-kind meta-analysis of time management literature. Their study pored over data from 158 separate studies spanning four decades, six continents and involving more than 53,000 respondents. Their conclusion? Yes, time management does work. Though maybe not as one might initially think.

Competition among sperm cells is fierce - they all want to reach the egg cell first to fertilize it. A research team now shows in mice that the ability of sperm to move progressively depends on the protein RAC1. Optimal amounts of active protein improve the competitiveness of individual sperm, whereas aberrant activity can cause male infertility.

Researchers have identified a potential way to eradicate the latent HIV infection that lies dormant inside infected immune cells. Studying human immune cells, the researchers showed that such cells have a natural alarm system that detects the activity of a specific HIV protein. Rather than attack the virus based on its appearance, this strategy is to attack the virus based on what it is doing -- vital activities that are required for the virus to exist.

The speed of light has come to 3D printing. Engineers have developed a new method that uses light to improve 3D printing speed and precision while also, in combination with a high-precision robot arm, providing the freedom to move, rotate or dilate each layer as the structure is being built. The method introduces the 'on-the-fly' ability to manipulate the original design layer by layer and pivot the printing direction without recreating the model.
