High-energy ion beams -- laser-like beams of atomic particles fired through accelerators -- have applications that range from inertial confinement fusion to the production of superhot extreme states of matter that are thought to exist in the core of giant planets like Jupiter and that researchers are eager to study. These positively charged ion beams must be neutralized by negatively charged electrons to keep them sharply focused. However, researchers have found many obstacles to the neutralization process.

Though abundance is a fundamental measure in ecology and environmental management, detecting all individuals in a population is usually impossible when monitoring, so estimates of abundance must account for imperfect detection.
Researchers developed the first method designed specifically to estimate population abundance from simultaneous counts of unmarked individuals over multiple sites, testing the methodology on three species of critically endangered vulture species in Cambodia.
Researchers conducted a 12-year study from 2010 to 2017 on ocelots (Leopardus pardalis) in the Brazilian Amazon, deploying 899 camera traps at 12 stations to determine habitat preferences, which were largely unknown.
Their findings show that ocelots are ubiquitous and adaptable, and seemingly abundant in protected areas or wherever there are forests populated with suitable prey.
The authors warn, however, that this does do not justify complacency regarding their conservation, as deforestation is destroying their habitat.
Analyzing the data on 10,077 citizen complaints lodged against the Chicago Police Department between 2011 and 2014, a pair of New York University researchers has found that just 2 percent of allegations made by black Chicagoans resulted in a recommendation for sanction against an officer, compared to 20 percent for white complainants and 7 percent for Latino complainants.
ITHACA, N.Y. - Emissions of methane from the industrial sector have been vastly underestimated, researchers from Cornell University and Environmental Defense Fund have found.
Using a Google Street View car equipped with a high-precision methane sensor, the researchers discovered that methane emissions from ammonia fertilizer plants were 100 times higher than the fertilizer industry's self-reported estimate. They also were substantially higher than the Environmental Protection Agency (EPA) estimate for all industrial processes in the United States.
Professor of Ghent University (Belgium) and Lead Researcher at the Institute of Biology and Biomedicine of the Lobachevsky University (UNN) Dmitri Krysko together with scientists from Germany, Professor Marcus Conrad and Professor Jose Pedro Friedmann Angeli recently published an article in the journal Nature Reviews Cancer, one of the highest-rated journals that occupies the 2nd line in the oncology section among 223 journals in this category and has an impact factor of 42.78 according to WoS data.
Swansea University has played a key role in transatlantic research to develop a greater understanding of megaviruses and their potential to cause life-threatening illnesses.
The findings, which have just been published in the prestigious Proceedings of the National Academy of Sciences of the United States of America (PNAS), examine the unexpected genes carried by these giant viruses found inside amoebae.
Researchers from the group of Marvin Tanenbaum at the Hubrecht Institute have shown that translation of the genetic information stored in our DNA is much more complex than previously thought. This discovery was made by developing a type of advanced microscopy that directly visualizes the translation of the genetic code in a living cell. Their study is published in the scientific journal Cell on June 6th.
BEER-SHEVA, ISRAEL...June 6, 2019 - Ben-Gurion University of the Negev (BGU) cyber security researchers have developed a new attack called "Malboard." Malboard evades several detection products that are intended to continuously verify the user's identity based on personalized keystroke characteristics.
TROY, N.Y. - Researchers at Rensselaer Polytechnic Institute have come up with a way to manipulate tungsten diselenide (WSe2) --a promising two-dimensional material--to further unlock its potential to enable faster, more efficient computing, and even quantum information processing and storage. Their findings were published today in Nature Communications.
Clinicians often feel that they have a role in preventing firearm injury. But few talk with patients about the risk of firearms and safe firearm practices during office visits.
Researchers at Dana-Farber Cancer Institute and the VA Boston Healthcare System have uncovered a new vital sign for gauging survival and likelihood of having an unplanned hospitalization in older patients with blood cancers: the speed at which they can walk.
Adversity early in life tends to affect a child's executive function skills -- their ability to focus, for example, or organize tasks.
Experiences such as poverty, residential instability, or parental divorce or substance abuse, also can lead to changes in a child's brain chemistry, muting the effects of stress hormones. These hormones rise to help us face challenges, stress or to simply "get up and go."
Creating a municipally funded team to provide intensive services to chronically homeless people who use a large amount of public services can help the individuals get off the streets, while also reducing spending on services such as police services and emergency medical care, according to a new RAND Corporation study.
Irvine, Calif., June 5, 2019 -- A nanotechnology treatment derived from bone marrow stem cells has reversed multiple sclerosis symptoms in mice and could eventually be used to help humans, according to a new study led by University of California, Irvine researchers.
