New drivers between the ages of 15 and 25 account for nearly half of the more than one million road deaths that occur worldwide each year, according to the World Health Organization. Educational programs often use fear-based messaging and films of crash scenes to reduce risky driving behavior among young people. But does this “scary” approach work?
Topological insulators are electron are superhighways on their edges and insulators everywhere else. Researchers used a process called high harmonic generation to separately probe electron behavior in both of those domains.
Bringing in individuals from other populations can help maintain genetic diversity--and an isolated population's ability to reproduce and survive.
A new study by researchers at University of California San Diego School of Medicine found delayed time between abnormal stool-based screening and subsequent colonoscopy was associated with an increased risk of a cancer diagnosis and death from colorectal cancer.
PPPL scientists have created a plan using liquid lithium to keep the full force of extreme and potentially damaging heat from hitting the divertor region that will release heat from future tokamak fusion facilities.
A study by Indiana University found Medicaid waivers increased Medicaid acceptance at residential treatment facilities.
GRAND RAPIDS, Mich. (Feb. 2, 2021) — What does bile acid production in the digestive tract have to do with Parkinson’s disease?
Some cities’ self-reported emissions are as much as 145 percent below standardized estimates, distorting the data on which climate change policy actions are based.
Florida State University researchers seeking to make newer, more energy efficient materials have made a breakthrough in understanding how structure dictates electron transfer across surfaces. It all has to do with how the molecules are positioned. Ken Hanson, associate professor of chemistry, and his colleagues found that the way molecules assemble on an inorganic material plays a key role in how energy and electrical current move across these interfaces, thus driving the functionality.
During the COVID-19 pandemic, Johns Hopkins Medicine Media Relations is focused on disseminating current, accurate and useful information to the public via the media. As part of that effort, we are distributing our “COVID-19 Tip Sheet: Story Ideas from Johns Hopkins” every other Tuesday.
Scientists are hoping advances in cancer research could lead to a day when a patient's own immune system could be used to fight and destroy a wide range of tumors. Cancer immunotherapy has some remarkable successes, but its effectiveness has been limited to a relatively small handful of cancers. In APL Bioengineering, researchers describe how advances in engineering models of tumors can greatly expand cancer immunotherapy's effectiveness to a wider range of cancers.
Foods will sometimes get stuck to a heated surface, even if oil or a nonstick frying pan is used. Scientists have investigated the fluid properties of oil on a flat surface and their work, reported in Physics of Fluids, shows convection may be to blame. When the pan is heated from below, a temperature gradient is established in the oil film, as well as a surface tension gradient. This gradient sets up a type of convection known as thermocapillary convection.
The “second wave” of the coronavirus pandemic has placed much blame on a lack of appropriate safety measures. However, due to the impacts of weather, research suggests two outbreaks per year are inevitable. Though face masks, travel restrictions, and social distancing guidelines help slow the number of new infections in the short term, the lack of climate effects incorporated into epidemiological models presents a glaring hole that can cause long-term effects. In Physics of Fluids, researchers discuss the impacts of these parameters.
Some promising biosensors and medical devices work well within pristine laboratory environments but may stop working once exposed to real-world conditions. A thick layer of foulants will quickly cover biosensors, and there is no good way to revive them once they quit working. Essentially, a biosensor is only as good as its antifouling properties. In APL Materials, researchers review a variety of approaches developed to combat fouling.
In a new study published in Blood, the official journal of the American Society of Hematology, Moffitt researchers show that immune dysregulation can directly affect the efficacy of CAR T therapy in patients with diffuse large B-cell lymphoma.
Volcanologists from the University of Georgia and two Swiss universities found a link between carbon dioxide and the volume of gas trapped in magma, which could help predict the intensity and magnitude of a volcanic eruption.
New research finds that satisfied customers mean increased profits even for public utilities that don’t face competition. Professors found that customer satisfaction does not lead to increased profits via higher rates or greater demand suggests current regulatory controls are effective. Their findings suggest regulators should view investments in customer satisfaction as recoverable costs.
A study published today in the New England Journal of Medicine provides the most definitive evidence to date that, of the two drugs recommended for light sedation of patients receiving mechanical ventilation in the ICU, one is as effective and safe as the other.
The majority of African American men return to prison within one to three years of their first release. A study explores why re-entry programs are not as effective for them when compared to others. Researchers suggest a holistic approach that addresses psychological and historical trauma in conjunction with the environmental factors that perpetuate the stigma justice-involved African American men experience. The approach accounts for negative associations developed in the centuries of oppression and segregation that shape their current societal interactions.
