Topological insulators (TIs) are bulk insulating materials that nonetheless exhibit metallic conductivity on their surfaces. This conductivity is guaranteed by the bulk band structure's topology--the surface features these states as long as the symmetry defining the topological index remains the same.
WASHINGTON, D.C. (March 16, 2020)--Latino/a adolescents with a family member who was detained or deported beginning as early as 2017 were at high risk of suicidal thoughts, early alcohol use, and risky behaviors that can lead to school failure and chronic health problems. The findings were published today in JAMA Pediatrics.
What The Study Did: Researchers in this survey study of nearly 550 Latino or Latina adolescents looked at how family member detention or deportation was associated with later suicidal thoughts, alcohol use or clinically significant externalizing behaviors such as rule-breaking and aggressive behaviors.

New insights into the architecture of the brain have been revealed by scientists at the Wellcome Sanger Institute, the Wellcome-MRC Cambridge Stem Cell Institute and their collaborators. The researchers discovered that cells in the cerebral cortex of mice, called astrocytes, are more diverse than previously thought, with distinct layers of astrocytes across the cerebral cortex that provide the strongest evidence to date of their specialization across the brain.
Arctic and Antarctic ice loss will account for about one-fifth of the warming that is projected to happen in the tropics, according to a new study led by Mark England, a polar climate scientist at Scripps Institution of Oceanography at the University of California San Diego, and Lorenzo Polvani, the Maurice Ewing and J. Lamar Worzel Professor of Geophysics at Columbia Engineering, England's doctoral supervisor.
Measures against overfishing tend to protect young, immature fish through measures such as minimum-landing sizes. However, a team of researchers led by Professor Robert Arlinghaus from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) and the Humboldt-Universität zu Berlin recommends also keeping the particularly large megaspawners alive in addition to the youngsters. This type of management achieves good compromises between the demands of commercial and recreational fisheries and the desire to conserve the reproductive capacity of fish populations.
ITHACA, N.Y. - In 2017, when interviewers asked Latino community members in San Antonio, Texas, about their top environmental concerns, the answers took researchers by surprise.
Poverty. Inequality. Education. Racism.
"They started bringing up things that don't typically come up in environmental studies," said Neil Lewis Jr., assistant professor of communication in the College of Agriculture and Life Sciences at Cornell University. "So, we decided to conduct a survey to see if this was something unique to the group in San Antonio, or if it's a broader phenomenon."
There are plenty of good reasons to make sure children get enough sleep, but their parents' evening peace is nowhere near the most important one.
"If we make sure our children get enough sleep, it can help protect them from mental health problems," says Bror M. Ranum, a PhD candidate at the Norwegian University of Science and Technology's (NTNU) Department of Psychology.
NASA's Aqua satellite passed over the Southern Indian Ocean and captured an image of a well-developed Tropical Cyclone Herold at hurricane strength, east of Madagascar.
Herold formed on March 13 as Tropical Cyclone 22S and once it intensified into a tropical storm, it was renamed Herold. Herold continued to strengthen and is now at hurricane-force.
A LEGO brick could survive in the ocean for as many as 1,300 years, according to new research.
A study led by the University of Plymouth examined the extent to which items of the ever-popular children's toy were worn down in the marine environment.
By measuring the mass of individual bricks found on beaches against equivalent unused pieces and the age of blocks obtained from storage, researchers estimated that the items could endure for anywhere between 100 and 1,300 years.
A clear majority of participants in a national survey about the zero-tolerance policy on the United States/Mexico border strongly opposed separating immigrant families and charging the parents as criminals, according to Baylor University research.
Researchers analyzed data from the Public Religion Research Institute's June 2018 Immigration Survey, which included questions about respondents' views on how to restrict or accommodate immigrants or refugees -- such as build a border wall or pass a law to prevent refugees from entering the United States.
A new study from the University of Birmingham has shown that Faecal Microbiota Transplants (FMT) are highly successful in treating patients with Clostridioides difficile (C.diff) infection.
Published in EClinical Medicine, results from the first licenced English stool bank, which supplies FMT treatment to patients in the NHS, have shown that in 78% of cases the patient's diarrhoea had stopped and had not returned in the 90 days after treatment.
New research lends credence to an unorthodox retelling of the story of early Earth first proposed by a geophysicist at Scripps Institution of Oceanography at UC San Diego.
In a study appearing March 15 in the journal Earth and Planetary Science Letters, Scripps Oceanography researchers Dave Stegman, Leah Ziegler, and Nicolas Blanc provide new estimates for the thermodynamics of magnetic field generation within the liquid portion of the early Earth's mantle and show how long that field was available.
he molecule NCAM2, a glycoprotein from the superfamily of immunoglobulins, is a vital factor in the formation of the cerebral cortex, neuronal morphogenesis and formation of neuronal circuits in the brain, as stated in the new study published in the journal Cerebral Cortex. The deficit of NCAM2 causes an incorrect migration of neurons and alters the morphology, cytoskeleton and functionality of these cells in the central nervous system.
In recent years, the development of quantum computers beyond the capability of classical computers has become a new frontier in science and technology and a key direction to realize quantum supremacy. However, conventional quantum computing has a serious challenge due to quantum decoherence effect and requires a significant amount of error correction in scaling quantum qubits.
