Stir lots of small particles into water, and the resulting thick mixture appears highly viscous. When this dense suspension slips through a nozzle and forms a droplet, however, its behavior momentarily reveals a decidedly non-viscous side. University of Chicago physicists recorded this surprising behavior in laboratory experiments using high-speed photography, which can capture action taking place in one hundred-thousandths of a second or less.

Complex organic compounds, including many important to life on Earth, were readily produced under conditions that likely prevailed in the primordial solar system. Scientists at the University of Chicago and NASA Ames Research Center came to this conclusion after linking computer simulations to laboratory experiments.

Katherine Hepburn famously said of her slim physique: “What you see before you is the result of a lifetime of chocolate.” New evidence suggests she may have been right.

A single-center study found that percutaneous coronary intervention (PCI) procedures performed during the middle of the night do not adversely affect the safety and effectiveness of procedures performed the next day by the same operator.

Omega-3 fatty acids have been shown to have great health benefits. Omega-3 fatty acids are found naturally in fish and fish products. Scientists at Virginia Tech have now demonstrated that it may be possible to achieve the suggested daily intake of omega-3 fatty acids in a single serving of a savory-flavored yogurt, providing an easily incorporated dietary source for these valuable fatty acids.

Treatment areas of ambulances fared well when tested for dangerous bacteria, according to a new study published in the April issue of the American Journal of Infection Control, the official publication of External link APIC - the Association for Professionals in Infection Control and Epidemiology. Approximately six percent of sites sampled in Chicago-area ambulances tested positive for Staphyloccocus aureus (S. aureus), a bacterium that can cause serious infections and can easily acquire resistance to potent antibiotics.

The use of stars, planets and stellar constellations for navigation was of fundamental importance for mankind for thousands of years. Now a group of scientists at the Max-Planck Institute for Extraterrestrial Physics in Garching, Germany, have developed a new technique using a special population of stars to navigate not on Earth, but in voyages across the Universe. Team member Werner Becker presented their work at the National Astronomy Meeting in Manchester on Friday 30 March.

In addition to being among his most vibrant and celebrated works, Vincent van Gogh's series of sunflower paintings also depict a mutation whose genetic basis has, until now, been a bit of a mystery.
In a study published March 29 in the journal PLoS Genetics, however, a team of University of Georgia scientists reveals the mutation behind the distinctive, thick bands of yellow "double flowers" that the post-Impressionist artist painted more than 100 years ago.

When tropical marine cone snails sink their harpoon-like teeth into their prey, they inject paralyzing venoms made from a potent mix of more than 100 different neurotoxins.
Biologists have known for more than a decade that the genes which provide the recipes for cone snail toxins are among the fastest-evolving genes in the animal kingdom, enabling these predatory gastropods to constantly refine their venoms to more precisely target the neuromuscular systems of their prey.
