Scientists at EPFL have developed a new method to synthesize and screen thousands of macrocyclic compounds, a family of chemicals that are of great interest in the pharmaceutical industry. The study is published in Science Advances.
Migration patterns in present-day Denmark shifted at the beginning of the Nordic Bronze Age, according to a study published August 21, 2019 in the open-access journal PLOS ONE by Karin Frei of the National Museum of Denmark and colleagues. Migrants appear to have come from varied and potentially distant locations during a period of unprecedented economic growth in southern Scandinavia in the 2nd millennium BC.
People in Croatia during the 5th to 6th centuries may have used cranial modifications to indicate their cultural affiliations, according to a study published August 21, 2019 in the open-access journal PLOS ONE led by Ron Pinhasi of the University of Vienna and Mario Novak of the Institute for Anthropological Research in Zagreb, Croatia.
It has long been thought that the brain size of anthropoid primates—a diverse group of modern and extinct monkeys, humans, and their nearest kin—progressively increased over time. New research on one of the oldest and most complete fossil primate skulls from South America shows instead that the pattern of brain evolution in this group was far more checkered. The study, published today in the journal Science Advances and led by researchers from the American Museum of Natural History, the Chinese Academy of Sciences... Читать дальше...
Theoretical physicists at Trinity College Dublin are among an international collaboration that has built the world's smallest engine—which, as a single calcium ion, is approximately ten billion times smaller than a car engine.
Carbon reservoirs in the soil of boreal forests are being released by more frequent and larger wildfires, according to a new study involving a University of Guelph researcher.
Physicists have found "electron pairing," a hallmark feature of superconductivity, at temperatures and energies well above the critical threshold where superconductivity happens.
A research team led by the University of California San Diego has discovered the root cause of why lithium metal batteries fail—bits of lithium metal deposits break off from the surface of the anode during discharging and are trapped as "dead" or inactive lithium that the battery can no longer access.
Online hate thrives globally through self-organized, scalable clusters that interconnect to form resilient networks spread across multiple social media platforms, countries and languages, according to new research published today in the journal Nature. Researchers at the George Washington University developed a mapping model, the first of its kind, to track how these online hate clusters thrive. They believe it could help social media platforms and law enforcement in the battle against hate online.
Marek's disease—a highly contagious viral disease caused by a herpesvirus—is a constant threat to poultry worldwide. It is also one of the most preventable diseases with vaccination. However, while vaccines prevent poultry from becoming sick with symptoms of the virus, they do not prevent virus spread and mutation—considered the main reason for increased virus virulence, or severity, in field strains in U.S. commercial flocks.
Southwestern Kansas in the 1930s saw some of the worst dust storms ever recorded in the U.S., when apocalyptic clouds of heavy dust terrified and even killed people, livestock and wildlife.
The taut rope that was lowering an underwater listening station to the ocean's floor collapsed on the tug boat's deck with a slap, signaling to the crew on board that their mission was complete.
Researchers at Binghamton University, State University of New York researchers have found a way to improve the performance of tiny sensors that could have wide-reaching implications for electronic devices we use every day.
Physicists from Russia and Europe have demonstrated the real possibility of using superconductor/ferromagnet systems to create magnonic crystals, which will be at the core of spin-wave devices to come in the post-silicon era of electronics. The paper was published in the journal Advanced Science.
Researchers have developed a method of chemical imaging which identifies colon cancer more accurately and efficiently than traditional methods.
An international research team at the Swiss Light Source (SLS) has set a new tomography world record using a rotary sample table developed at the HZB. With 208 three-dimensional tomographic X-ray images per second, they were able to document the dynamic processes involved in the foaming of liquid aluminium. The method is presented in the journal Nature Communications.
Those who wish to leave their own country of origin in the European Union (EU) can currently do so without complications: with the right to freedom of movement, the EU offers its citizens unique conditions for migration. A study by the Universities of Göttingen, Bremen and Cologne has now shown that Germany and United Kingdom are the most popular destination countries for migration within Europe. Their research was published in the Journal of Ethnic and Migration Studies.
Almost a quarter of the universe stands literally in the shadows. According to cosmologists' theories, 25.8% of it is made up of dark matter, whose presence is signaled essentially only by its gravitational pull. What this substance consists of remains a mystery. Hermann Nicolai, Director at the Max Planck Institute for Gravitational Physics in Potsdam, and his colleague Krzysztof Meissner from the University of Warsaw have now proposed a new candidate—a superheavy gravitino. The existence of this... Читать дальше...
Round numbers can be powerful marketing tools, increasing people's sense of accomplishment as they work towards goals in areas like finances or weight loss, according to new Washington State University research.
Weather forecasting is a typical problem of coupling big data with physical-process models, according to Prof. Pingwen Zhang, an academician of Chinese Academy of Sciences, Director of the National Engineering Laboratory for Big Data Analysis and Application Technology, Director of the Center for Computational Science & Engineering, Peking University. Prof. Zhang is the corresponding author of a collaborated study by Peking University and Institute of Atmospheric Physics, Chinese Academy of Sciences.
Stomata are plant-specific epidermal structures that consist of paired guard cells surrounding a pore. The opening and closing of these micro-valves facilitate carbon dioxide uptake for photosynthesis and reduce excessive water loss in plants.
Chinese cabbage is part of a crop family that must be exposed to cold temperatures for a particular period of time in order to flower. Scientists have succeeded in comprehensively identifying the long noncoding ribonucleic acids (IncRNAs) that are expressed when Chinese cabbage is temporarily exposed to cold temperatures for four weeks. LncRNAs that are known to be involved in responding to cold in Arabidopsis thaliana do not exist in Chinese cabbage, which suggests that Chinese cabbage has its own independent mechanism for flowering.
Human urine contains hundreds of small molecules that tell us about our health, diet and well-being. Associate Professor Frans Mulder, in collaboration with the University of Florence, has been successful in developing a new method for analyzing the components of a urine sample. Using this method, the analysis becomes both cheaper and more accurate.
A new Northwestern University study discovered that spaceflight—both aboard a space shuttle or the International Space Station (ISS)—has a consistent effect on the gut microbiome
