With warming temperatures, average snowfall frequency is estimated to decline across the Pacific Northwest by 2100—and at a faster rate if greenhouse emissions are not reduced, according to a new Portland State University study.

All parents want their children to get the best education possible, so how do school districts allow parents/guardians to have a say in where their child goes to school while still meeting diversity goals for the student body? New research in an upcoming addition of the INFORMS journal Operations Research has a solution, just in time for children to return to school for the 2019-2020 year.
Researchers from Texas A&M University published new research in the INFORMS journal Marketing Science, which shows that retailers' branded mobile apps are very effective in increasing customer engagement, increasing sales on multiple levels, not just on the retailer's website, but also in its stores. At the same time, apps increase the rate of returns, although the increase in sales outweighs the...
Another Atlantic Ocean basin depression formed while Hurricane Dorian is still wreaking havoc on the Bahamas and affecting the southeastern U.S. Infrared imagery from NASA's Aqua satellite shows that Tropical Depression 7 in the western Gulf of Mexico has developed powerful thunderstorms with heavy rain capabilities. That potential for heavy rainfall includes southern Texas and northeastern...
NASA's Aqua satellite passed over the Eastern Pacific Ocean and provided an image of Hurricane Juliette as its eye began to emerge. Juliette has grown into a major hurricane, about 450 miles southwest of the southern tip of Baja California, Mexico.
In the early hours of Tuesday, September 3, Hurricane Dorian had been stationary over the island of Grand Bahama for 18 hours, most of the time as a category 5 hurricane. Storm-total rain accumulation over parts of Grand Bahama and Abaco Islands have exceeded 24 inches according to NASA satellite-based estimates.
Pity the poor blemished banana. In a society that equates beauty with quality, the perception that blemished produce is less desirable than its perfect peers contributes to 1.3 billion tons of wasted food a year globally.
An explosion is a complex event involving quickly changing temperatures, pressures and chemical concentrations. In a paper in the Journal of Applied Physics a special type of infrared laser, known as a swept-wavelength external cavity quantum cascade laser (swept-ECQCL), is used to study explosions. This versatile instrument has a broad wavelength tuning range that allows the measurement of...
The utterances of Old World monkeys, some of our primate cousins, may be more sophisticated than previously realized—but even so, they display constraints that reinforce the singularity of human language, according to a new study co-authored by an MIT linguist.
Money can't buy you happiness, but it could motivate you to live a better life.
Providing a glimpse the hidden workings of evolution, a group of researchers at UC Santa Barbara have discovered that embryos that appear the same can start out with surprisingly different instructions.
A team of scientists has discovered a new possible pathway toward forming carbon structures in space using a specialized chemical exploration technique at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab).
A new study using mass spectrometry is helping piece together what happens when DNA that has been sensitized by the oncology drug 5-fluorouracil is subjected to the ionising radiation used in radiotherapy.
Practically parking over the Bahamas for a day and a half, Hurricane Dorian pounded away at the islands Tuesday in a watery onslaught that devastated thousands of homes, trapped people in attics and crippled hospitals. At least five deaths were reported, with the full extent of the damage far from clear.
In "Intra- and Interspecific Variation in Production of Bile Acids that Act As Sex Pheromones in Lampreys," published in Physiological and Biochemical Zoology, Tyler J. Buchinger and others find that sexual selection may play a role in the evolution of lamprey pheromones.
Researchers have shed new light on how some geese can fly high for long periods of time, according to a study published today in eLife.
Corals are shown to recycle their own waste ammonium using a surprising source of glucose—a finding that reveals more about the relationship between corals and their symbiotic algae.
A phenomenon that is well known from chaos theory was observed in a material for the first time ever, by scientists from the University of Groningen, the Netherlands. A structural transition in the ferroelastic material barium titanate, caused by an increase or decrease in temperature, resembles the periodic doubling seen in non-linear dynamical systems. This 'spatial chaos' in a material was...
The European Space Agency said Tuesday it had altered the trajectory of one of its observation satellites to avoid a possible collision with a craft operated by Elon Musk's SpaceX.
Hurricane Dorian crept towards the southeast coast of the United States on Tuesday, weakening slightly but remaining a dangerous storm after leaving a trail of death and destruction in the Bahamas.
Researchers at the University of Göttingen have developed a new method that takes advantage of the unusual properties of graphene to electromagnetically interact with fluorescing (light-emitting) molecules. This method allows scientists to optically measure extremely small distances, in the order of 1 ångström (one ten-billionth of a meter) with high accuracy and reproducibility for the first...
Prospective digital data storage devices predominantly rely on novel fundamental magnetic phenomena. The better we understand these phenomena, the better and more energy efficient the memory chips and hard drives we can build. Physicists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the Helmholtz-Zentrum Berlin (HZB) have now completed the essential fundamental work for future storage...
Plasmonic nanostructures have been widely used for enhancing light-matter interactions due to the strong local field enhancement in deep subwavelength volumes.
Professor Hongsoo Choi's research team in the Department of Robotics Engineering & DGIST-ETH Microrobot Research Center (DEMRC) at DGIST (President Young Kuk) succeeded in developing a biodegradable micro-robot that can perform hyperthermia treatment and control drug release. This research can treat cancer cells through hyperthermia and controlled drug release more precisely and systematically,...
A monarch butterfly had just emerged from its chrysalis when Emilie Snell-Rood reached into its cage, grabbed it carefully to take measurements and photographs, then placed it inside a tall and breezy tent. There it would strengthen its wings for a day or two in relative safety before being released in time to begin a 2,000-mile trek to southern Mexico.
