Brazilian researchers have managed to decipher the structure of a protein found in parasites that cause neglected tropical diseases, paving the way to the development of novel medications. Thanks to the discovery it will be possible to seek more potent molecules capable of destroying the pathogens directly, with fewer adverse side-effects for patients.
HANOVER, N.H. - January 7, 2021 - The number of "extreme streamflow" events observed in river systems have increased significantly across the United States and Canada over the last century, according to a study from Dartmouth College.
In regions where water runoff from snowmelt is a main contributor to river streamflow, the study found a rise in extreme events, such as flooding.
In drought-prone regions in the western and southeastern U.S., the study found that the frequency of extreme low-flow events has also become more common, particularly during summer and fall.
Abu Dhabi, UAE, January 6, 2021: To provide effective aid to children who live in areas of conflict it is necessary to understand precisely how they have been impacted by the crises around them. One area of importance is the effect of conflict and trauma on a child's development and education.
Methylcyclopentadiene (MCPD) is an important monomer in the production of RJ-4 fuel, a high-energy-density rocket fuel, and various valuable products.
Currently, MCPD is mainly obtained from the by-products of petroleum cracking tar at a very low yield of ~ 0.7 kg ton-1 and high price of ~10,000 USD ton-1. The exploration of highly efficient processes to convert renewable biomass to MCPD is stimulated by the energy and environment problems.
Using synchrotron radiation at SPring-8 - a large-scale synchrotron radiation facility - Tohoku University, Toshiba Corporation, and the Japan Synchrotron Radiation Research Institute (JASRI) have successfully imaged the magnetization dynamics of a hard disk drive (HDD) write head for the first time, with a precision of one ten-billionth of a second. The method makes possible precise analysis of write head operations, accelerating the development of the next-generation write heads and further increasing HDD capacity.
A first-of-its-kind study conducted under the bed of the Dead Sea reveals that a devastating earthquake measuring 6.5 on the Richter scale is expected to hit our region in the coming years. The study showed that an earthquake of this magnitude occurs in the land of Israel on an average cycle of between 130 and 150 years, but there have been cases in history where the lull between one earthquake and another was only a few decades long.
Maybe you're like us. We're the folks who are on our smartphones almost all the time, even when we're with others. We know it annoys a lot of people, but we do it anyway. Why?
Researchers at the Norwegian University of Science and Technology (NTNU) have looked at why people in cafés pull out their phones, and how this affects café life. Three main reasons they identified are: to delay or pause a conversation (interaction suspension); to get out of a conversation (deliberately shielding interaction); and to share something with others (accessing shareables).
In the digital age, data traffic is growing at an exponential rate. The demands on computing power for applications in artificial intelligence such as pattern and speech recognition in particular, or for self-driving vehicles, often exceeds the capacities of conventional computer processors. Working together with an international team, researchers at the University of Münster are developing new approaches and process architectures which can cope with these tasks extremely efficient.
Memphis, Tenn. (January 5, 2021) - A paper written by Arash Shaban-Nejad, PhD, MPH, an assistant professor, and Nariman Ammar, PhD, a postdoctoral fellow, both at the Center for Biomedical Informatics in the Department of Pediatrics at the University of Tennessee Health Science Center, was recently published in the Journal of Medical Internet Research - Medical Informatics. The paper discussed how an artificial intelligence system developed by the researchers was used to diagnose and treat children and adults who suffer from Adverse Childhood Experiences (ACEs).
Toronto - New research from UHN's Peter Munk Cardiac Centre (PMCC) shows statins, commonly prescribed to lower cholesterol and reduce the risk of heart disease and stroke, may also protect the heart from damaging side-effects of early breast cancer treatment.
The world has experienced dramatic urbanization in recent decades. According to the latest report from the United Nations (UN), the global population in 2018 was 7.6 billion and the urban population was 4.2 billion. By 2050, the global population is expected to soar to 9.7 billion, with 68% of the population living in urban areas. (Note 1)
A recent study finds that, while youth think all bullying is bad, non-immigrant adolescents object less to bullying when the victim is an immigrant. However, the study found that the more contact immigrant and non-immigrant children had with each other, the more strongly they objected to bullying.
One sweaty, huffing, exercising person emits as many chemicals from their body as up to five sedentary people, according to a new University of Colorado Boulder study. And notably, those human emissions, including amino acids from sweat or acetone from breath, chemically combine with bleach cleaners to form new airborne chemicals with unknown impacts to indoor air quality.
An effective response to a pandemic like the COVID-19 will only be successful if people voluntarily follow the rules and guidelines of decision-makers and experts. Many of the required measures, such as avoiding social contact and significantly changing our daily habits require a strong commitment. Other necessary actions, such as regular hand washing, are often impossible to monitor and enforce. Adherence to the guidelines thus depends on people's personal commitment.
BEER-SHEVA, Israel...January 5, 2021 - Reopening Florida elementary and high schools in September was followed by increased COVID-19 infections, according to data analyzed by Ben-Gurion University of the Negev, Harvard Medical School and Tel Aviv University researchers.
The findings were just published in Archives of Disease in Childhood.
Florida is one of the few states that provides incidence of infections by exact age and county.
