African swine fever (ASF) is a devastating infectious disease in swine and has been catastrophic for the global pig industry. In 2018, ASFV was transmitted to pigs in China and ten other Asian countries, which mauled heavily pig industry in these areas. The fact demonstrates that ASF is hard to be controlled by culling infected pigs alone in China, and the development and application of an efficacious vaccine is urgently needed. Different vaccine strategies for ASF have been evaluated in the past decades.
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.
On March 11, 2011, a magnitude 9 earthquake struck under the seabed off Japan--the most powerful quake to hit the country in modern times, and the fourth most powerful in the world since modern record keeping began. It generated a series of tsunami waves that reached an extraordinary 125 to 130 feet high in places. The waves devastated much of Japan's populous coastline, caused three nuclear reactors to melt down, and killed close to 20,000 people.
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.
A new study examines energy inequality for income classes across 86 countries, from highly industrialised to developing ones, revealing extreme disparity in energy footprints, both within nations and globally.
In the first study of its kind, University of Leeds researchers combined European Union and World Bank data to calculate the distribution of energy footprints, as well as what energy-intensive goods and services different income groups tend to spend their money on.
Scientists can now edit multiple sites in the genome at the same time to learn how different DNA stretches co-operate in health and disease.
Their researches on the lamprey brain has enabled researchers at Karolinska Institutet in Sweden to push the birth of the cortex back in time by some 300 million years to over 500 million years ago, providing new insights into brain evolution. The study is published in the scientific journal Nature Ecology & Evolution.
Males that face tougher competition for females risk having offspring with a greater number of harmful mutations in their genome than males without rivals. Researchers at Uppsala University have discovered this correlation in the beetle species Callosobruchus maculatus. Their study is published in the scientific journal Nature Ecology & Evolution.
Like many industries, big data is driving innovations in agriculture. Scientists seek to analyze thousands of plants to pinpoint genetic tweaks that can boost crop production--historically, a Herculean task. To drive progress toward higher-yielding crops, a team from the University of Illinois is revolutionizing the ability to screen plants for key traits across an entire field.
