A new study published in the Journal of the Association of Environmental and Resource Economists looks at the causal relationship between outdoor air pollution levels on nationwide university entry examination day and students' cognitive performance in Brazil.
Scientists thought asteroid Bennu's surface would be like a sandy beach, abundant in fine sand and pebbles, which would have been perfect for collecting samples. Past telescope observations from Earth's orbit had suggested the presence of large swaths of fine-grain material called fine regolith that's smaller than a few centimeters.
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...
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.
It was nearly 2 p.m. Tuesday when the Alenia C-27J Spartan, a U.S. Coast Guard aircraft, began its flight along the Orange County coast.

Scientists have developed a groundbreaking theory for calculating what's happening inside a proton traveling at the speed of light.
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...
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...
A team has developed a catalyst that can be used to both generate fuel and provide power.
A new study of the genetic profiles of wild and hatchery coho salmon demonstrates important distinctions in how the two types of fish form mating pairs.
New understanding of cellular defects related to Cystic Fibrosis (CF) could help pave the way for treatment.
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.
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.
The compound works by hindering a key pathway that cancer cells rely upon to hoard energy, and is already undergoing clinical trials.
LEO carves out a new type of locomotion somewhere between walking and flying.
Metformin, a drug commonly prescribed against diabetes, holds promise against a rare type of childhood brain tumor in laboratory studies, an international team of researchers.
Using data from NASA OSIRIS-REx mission, scientists concluded that asteroids with highly porous rocks, such as Bennu, should lack fine-grained material on their surfaces.

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.
Princeton professor David MacMillan on Wednesday won the Nobel Chemistry Prize for his work developing a new tool to scale up chemical reactions in an environmentally friendly way, known as "organocatalysis."
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.
An international agreement to protect the ozone layer is expected to prevent 443 million cases of skin cancer and 63 million cataract cases for people born in the United States through the end of this century, according to new research.
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...
