Fluorescent Probes Developed for Molecular Imaging of Copper in the Brain

The value of copper has risen dramatically in the 21st century as many a thief can tell you, but in addition to the thermal and electrical properties that make it such a hot commodity metal, copper has chemical properties that make it essential to a healthy brain.

Fluctuation X-ray Scattering Shows Potential for Determining Behavior of Protein Mixtures

To learn how biological molecules like proteins function, scientists must first understand their structures. Almost as important is understanding how the structures change, as molecules in the native state do their jobs.

Confocal Microscopy and Fluorescence Lifetime Imaging Combined can Help Detect Cancer Noninvasively

More effective detection and diagnosis of oral cancer could result from an advance in noninvasive imaging of epithelial tissue by a Texas A&M University researcher who says her research has the potential to change the way doctors initially look for precancerous and cancerous areas in a patient’s mouth.

Electron Microscopy Imaging Study Provides New Insight into LED Efficiency

From the high-resolution glow of flat screen televisions to light bulbs that last for years, light-emitting diodes (LEDs) continue to transform technology. The celebrated efficiency and versatility of LEDs—and other solid-state technologies including laser diodes and solar photovoltaics—make them increasingly popular. Their full potential, however, remains untapped, in part because the semiconductor alloys that make these devices work continue to puzzle scientists.

Researchers Synthesize Novel MOF Filtration Material for Petroleum Refining

A newly synthesized material might provide a dramatically improved method for separating the highest-octane components of gasoline. Measurements at the National Institute of Standards and Technology (NIST) have clarified* why. The research team, which included scientists from NIST and several other universities, has published its findings in the journal Science.

Multitasking Neurons Improve Computational Power of the Brain

Over the past few decades, neuroscientists have made much progress in mapping the brain by deciphering the functions of individual neurons that perform very specific tasks, such as recognizing the location or color of an object.

Nanoscale Magnetic Material When Sorted on a Lattice Align in Chain Pattern

Physicists at the Ruhr-Universität Bochum (RUB) have found out how tiny islands of magnetic material align themselves when sorted on a regular lattice - by measurements at BESSY II. Contrary to expectations, the north and south poles of the magnetic islands did not arrange themselves in a zigzag pattern, but in chains.

CEA-Leti Announce Success of HELIOS Program

CEA-Leti said today that Europe is strongly positioned to design and manufacture volume silicon photonics devices because of the success of the recently completed HELIOS program. The €8.5 million European Commiss...

Researchers Optimize Scanning Electrochemical Microscopy to Measure Oxygen Consumption of Individual Cells

How active a living cell is can be seen by its oxygen consumption. The method for determining this consumption has now been significantly improved by chemists in Bochum. The problem up to now was that the measuring electrode altered the oxygen consumption in the cell's environment much more than the cell itself.

New Infrared-UV Laser Method to Accurately Determine Structure of Proteins

3D structures of biological molecules like proteins directly affect the way they behave in our bodies. EPFL scientists have developed a new infrared-UV laser method to more accurately determine the structure of proteins containing thousands of atoms.
