How Taste Is Perceived In The Brain

December 10, 2015

The bitter cortex (red) and sweet cortex (green) are about 2 millimeters apart in the mouse brain. (Charles S. Zuker, Ph.D./Columbia University Medical Center) People and other mammals rely on taste to guide food choices. For example, [more...]

Measuring Nanoscale Features with Fractions of Light

December 6, 2015

Drawing illustrates how tiny changes in wavy images scattered from lines in a grid-like array can be reconstructed when paired with advanced optical and computational techniques. Lines are 15 nanometers wide, 30 times smaller than the [more...]

Detecting Cancer Cells Before They Form Metastases

November 25, 2015

Target cells (green) stick to the microarray platform (red). (Credit: Michael Hirtz / KIT) Many tumors spread: Single cancer cells migrate with blood flow through the body before they settle in new tissue. In this way, metastases may be [more...]

An Engineered Surface Unsticks Sticky Water Droplets

September 1, 2015

The lotus effect has inspired many types of liquid repelling surfaces, but tiny water droplets stick to lotus leaf structures. Now, researchers at Penn State have developed the first nano/micro-textured highly slippery surfaces able to [more...]

Hydrophobic Nanostructures Keep Dry Underwater

September 1, 2015

By mimicking naturally-occurring nanostructures found in things like water striders, spiders and lotus leaves, scientists have created hydrophobic surfaces that could prove invaluable for everything from pipes to boats and submarines. Now [more...]

Male or Female: The Difference Is in the Brain?

August 15, 2015

Catherine S. Woolley, a professor of neurobiology at Northwestern Univ.’s Weinberg College of Arts and Sciences, refused to study sex differences in the brain for 20 years. But in 2012, she discovered estrogens decreased inhibitory [more...]
