Newly available GPS data helps scientists better understand ionosphere

A new data source to help scientists better understand the ionosphere and its potential impact on communications and positioning, navigation, and timing—an essential utility for many critical operations—is now available to the public. The data, which was collected by sensors on GPS satellites in 2018, was released today through a collaborative effort by Los Alamos National Laboratory and the...

Researchers reach quantum networking milestone in real-world environment

A team from the U.S. Department of Energy's Oak Ridge National Laboratory, Stanford University and Purdue University developed and demonstrated a novel, fully functional quantum local area network, or QLAN, to enable real-time adjustments to information shared with geographically isolated systems at ORNL using entangled photons passing through optical fiber.

Novel quantum effect discovered in naturally occurring graphene

Usually, the electrical resistance of a material depends very much on its physical dimensions and fundamental properties. Under special circumstances, however, this resistance can adopt a fixed value that is independent of the basic material properties and "quantised" (meaning that it changes in discrete steps rather than continuously). This quantisation of electrical resistance normally occurs...

Novel quantum effect discovered in naturally occurring graphene

Under special circumstances, the electrical resistance of a material can adopt a fixed value that is independent from the basic material properties and 'quantized'. This 'quantization' normally occurs within strong magnetic fields at very low temperatures when electrons move in two-dimensions. Now, a research team has succeeded in demonstrating this effect at low temperatures in the almost...

Getting up to speed on the proton

A century ago, scientists first detected the proton in the atomic nucleus. Yet, much about its contents remains a mystery. Scientists report a new theory for understanding what's inside protons moving at the speed of light.

Record-breaking Texas drought more severe than previously thought

In 2011, Texas experienced one of its worst droughts ever. The dry, parched conditions caused over $7 billion in crop and livestock losses, sparked wildfires, pushed power grids to the limit, and reduced reservoirs to dangerously low levels. And according to a recent study led by geoscientists, the drought was worse than previously thought.

Bacteria enters through natural openings at edges of corn leaves to cause Goss's wilt

Goss's bacterial wilt and leaf blight is one of the most damaging diseases affecting corn. The most effective way to control this disease is to plant corn varieties that are resistant to the disease. In other words, growers avoid the disease by growing certain varieties of corn. In part, this is the easiest method because scientists don't yet know much about Goss's wilt.

New approach to skeletal age-estimation can help identify child remains

Forensic teams challenged with identifying skeletal remains may benefit from a new method of determining age in child remains when traditional methods, such as dental records, aren't available. New research from SFU archeologists finds that measuring cranial bones can provide one of the most comprehensive methods of estimating juvenile age.

Dwarf planet Vesta serves as a window to the early solar system

The dwarf planet Vesta is helping scientists better understand the earliest era in the formation of our solar system. Two recent papers involving scientists from the University of California, Davis, use data from meteorites derived from Vesta to resolve the "missing mantle problem" and push back our knowledge of the solar system to just a couple of million years after it began to form. The papers...
