Sudden bursts of heat that can damage the inner walls of tokamak fusion experiments are a hurdle that operators of the facilities must overcome. Such bursts, called "edge localized modes (ELMs)," occur in doughnut-shaped tokamak devices that house the hot, charged plasma that is used to replicate on Earth the power that drives the sun and other stars. Now researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have directly observed a possible and previously unknown process that can trigger damaging ELMs.
In April 2015, Nepal - and especially the region around the capital city, Kathmandu - was struck by a powerful tremor. An earthquake with a magnitude of 7.8 destroyed entire villages, traffic routes and cultural monuments, with a death toll of some 9,000.
However, the country may still face the threat of much stronger earthquakes with a magnitude of 8 or more. This is the conclusion reached by a group of earth scientists from ETH Zurich based on a new model of the collision zone between the Indian and Eurasian Plates in the vicinity of the Himalayas.
By combining deep learning algorithms and statistical methods, investigators from the Institute of Evolutionary Biology (IBE), the Centro Nacional de Análisis Genómico (CNAG-CRG) of the Centre for Genomic Regulation (CRG) and the Institute of Genomics at the University of Tartu have identified, in the genome of Asiatic individuals, the footprint of a new hominid who cross bred with its ancestors tens of thousands of years ago.
Idling in a long highway line of slowed or stopped traffic on a busy highway can be more than an inconvenience for drivers and highway safety officers.
It is one of the most vulnerable times for "secondary accidents," which often can be worse than an original source of the slowdown, according to the U.S. Department of Transportation's Federal Highway Administration. In fact, secondary crashes go up by a factor of almost 24 during the time that highway safety officials are assessing and documenting the crash site.
A mechanism which drives leukemia cell growth has been discovered by researchers at the University of Sussex, who believe their findings could help to inform new strategies when it comes to treating the cancer.
Acute myeloid leukemia (AML) is a devastating blood cancer with around 3,000 new cases annually in the UK.
Despite considerable improvement in patient survival over the last 50 years, the prognosis remains poor for many subsets of adults and children who suffer from the disease.
A study published in the February 2019 "Pediatrics" journal suggests the majority of gay fathers and their children continue to experience stigma with potentially harmful physical and psychological effects, despite legal, media and social advances. Study participants specifically cited structural stigma, such as state laws and beliefs of religious communities, as affecting their experiences in multiple social contexts.
BINGHAMTON, N.Y. - What do songs by artists like Jay-Z and Public Enemy have in common? They feature representations of 'cop voice,' a racialized way of speaking that police use to weaponize their voices around people of color, according to faculty at Binghamton University, State University of New York.
Fluvial landscapes and the availability of water are of paramount importance for human safety and socioeconomic growth. Hydrologists know that identifying the boundaries of floodplains is often the first crucial step for any urban development or environmental protection plan.
Floodplain zoning is usually performed using complex hydrodynamic models, but modeling results can vary widely across methods and until now there has been no available unifying framework for global floodplain mapping.
ANN ARBOR--The cyanobacteria blooms that plague western Lake Erie each summer are both an unsightly nuisance and a potential public health hazard, producing liver toxins that can be harmful to humans and their pets.
But the toxins produced in cyanobacteria blooms may also have protective effects on sand-grain-sized lake animals that ingest them, much as the toxins in milkweed plants protect monarch butterflies from parasites, according to a new study from University of Michigan ecologists.
New research, led by the University of Bristol, has shed new light on the eating habits of Neolithic people living in southeastern Europe using food residues from pottery extracts dating back more than 8,000 years.
With the dawn of the Neolithic age, farming became established across Europe and people turned their back on aquatic resources, a food source more typical of the earlier Mesolithic period, instead preferring to eat meat and dairy products from domesticated animals.
