"I'm so bored!" It's a typical complaint by teens in every era, but one that's growing more common for U.S. adolescents, especially girls.
New research at Washington State University has found that boredom is rising year after year for teens in 8th, 10th, and 12th grades, with greater increases for girls than boys.
"We were surprised to see that boredom is increasing at a more rapid pace for girls than boys across all grades," said Elizabeth Weybright, WSU researcher of adolescent development, who shared the findings in the Journal of Adolescent Health.
Ithaca, NY--Some "canaries" are 50 feet long, weigh 70 tons, and are nowhere near a coal mine. But the highly endangered North Atlantic right whale is sending the same kind of message about disruptive change in the environment by rapidly altering its use of important habitat areas off the New England coast. These findings are contained in a new study published in Global Change Biology by scientists at the Center for Conservation Bioacoustics (formerly the Bioacoustics Research Program) at the Cornell Lab of Ornithology and at Syracuse University.
Imagine having an electrode embedded in your brain in a surgical procedure that involves drilling holes in your skull to implant it. Now imagine going through an MRI scan for medical evaluation, when the metal electrode may react to the magnetic fields and vibrate, generate heat or even possibly damage the brain.
This is a reality that patients who need deep brain stimulation could face.
NASA's Terra satellite captured an image of Typhoon Kalmaegi as it moved into the Luzon Strait and continued to affect the northern Philippines.
On Nov. 19, Kalmaegi's western edge was in the Luzon Strait, while its southern quadrant was over the northern Philippines. The Luzon Strait is located between Taiwan and Luzon, Philippines. The strait connects the Philippine Sea to the South China Sea in the northwestern Pacific Ocean.
Did Donald Trump's 2016 presidential campaign benefit from voters' fears of immigrants in communities experiencing greater demographic change?
New research shows the answer is "no," a finding that contradicts the conventional wisdom and which surprised even the political scientists who conducted the study. Instead, those communities actually moved more toward the pro-immigration Democratic candidate.
AMES, Iowa - NASA's planet-hunting TESS Mission keeps giving astronomers new realities to examine and explain.
Case in point: astronomers using the tools of asteroseismology - the observations and measurements of a star's oscillations, or starquakes, that appear as changes in brightness - have learned more about two stars bright enough to be visible in a dark sky to the naked eye. These red-giant stars - older, "retired" stars no longer burning hydrogen in their cores - are known as HD 212771 and HD 203949.
Steep gradients of wind stress and potential temperature enable sustainable nearshore precipitation systems along the western coastal region of Korea, according to Prof. Dong-In Lee, lead scientist at the Group of Environmental Atmospheric Research (GEAR), Pukyong National University, and one of the authors of a recently published study.
When it comes to electronics, bigger usually isn't better. This is especially true for a new generation of wearable communication systems that promise to connect people, machines and other objects in a wireless "internet of things." To make the devices small and comfortable enough to wear, scientists need to miniaturize their components. Now, researchers in ACS Nano have made the tiniest radio-frequency antennas reported yet, with thicknesses of about 1/100 of a human hair.
Many people take electricity for granted -- the power to turn on light with the flip of a switch, or keep food from spoiling with refrigeration. But generating electricity from fossil fuels exacts a toll on health and the environment. Scientists estimate that these power plant emissions cause tens of thousands of premature deaths in the U.S. each year. Now, researchers report in ACS' Environmental Science & Technology that pollutant exposure varies with certain demographic factors.
In 2004, the United Nations Stockholm Convention banned the production and use of many persistent organic pollutants (POPs), such as dichlorodiphenyltrichloroethane (DDT) and polychlorinated biphenyls (PCBs). However, POP production and use continue in some nations that did not ratify the treaty, including India and other South Asian countries. Now, researchers reporting in ACS' Environmental Science & Technology have linked high levels of DDT in Indian immigrants in the U.S. with risk factors for diabetes.
OAK BROOK, Ill. - Ensembles created using models submitted to the RSNA Pediatric Bone Age Machine Learning Challenge convincingly outperformed single-model prediction of bone age, according to a study published in the journal Radiology: Artificial Intelligence.
Ensemble learning is a method in machine learning in which different models designed to accomplish the same task are combined into a single model.

Previous exposure to the pollutant DDT may contribute to the risk of diabetes among Asian Indian immigrants to the United States, according to a study from the University of California, Davis.
The study, published today in the American Chemical Society's journal Environmental Science & Technology, linked high levels of DDT, or dichlorodiphenyltrichloroethane, in Indian immigrants with risk factors for metabolic disease.
The TAILORx study published last year offered good news for women with early-stage ER-positive breast cancer who scored at intermediate risk for recurrence according to a genetic assay test. The study indicated that chemotherapy after surgery provided little advantage in overall survival for these women, so they could forgo the treatment.
Light is versatile in nature. In other words, it shows different characteristics when traveling through different types of materials. This property has been explored in various technologies, but the way in which light interacts with materials needs to be manipulated to get the desired effect. This is done using special devices called light modulators, which have the ability to modify the properties of light. One such property, called the Pockels effect, is seen when an electric field is applied to the medium through which light travels.
