The almost 15-million-year-old Nördlinger Ries is an asteroid impact crater filled with lake sediments. Its structure is comparable to the craters currently being explored on Mars. In addition to various other deposits on the rim of the basin, the crater fill is mainly formed by stratified clay deposits. Unexpectedly, a research team led by the University of Göttingen has now discovered a volcanic ash layer in the asteroid crater.
In a study of 558 college students, those who reported more symptoms associated with attention-deficit/hyperactivity disorder (ADHD) also reported higher levels of stress. Students reporting higher levels of ADHD symptoms also reported lower levels of resilience, according to the study published in the
Journal of College Counseling.
New research published in the British Educational Research Journal suggests a very strong association between socio-economic background and educational attainment throughout children's schooling in 4 low- and middle-income countries.
Foodborne disease outbreaks linked to the consumption of fresh produce have caused farmers to re-evaluate their practices. A recent analysis of a 27-year experiment comparing organic and conventional soil management indicates that animal-based composts do not promote pathogen survival and may even promote bacterial communities that suppress pathogens.
Studies on electrochemical CO2 conversion systems which can be used to obtain useful chemicals through conventional petrochemical processes while eliminating CO2, without polluting the environment, are essential for creating a carbon-neutral society. While significant progress has been made through a number of relevant studies, thus far, they have only been laboratory-scale in size. In fact, there are still many roadblocks to industrial application, such as the scaling up and development of suitable catalysts and electrodes.
WASHINGTON, April 6, 2021 -- With research increasingly showing the COVID-19 virus is transmissible via smaller droplets suspended in air, there is a growing concern current public health guidelines of mask wearing and social distancing are insufficient in combating its spread in indoor environments, like prisons, hospitals, and meatpacking plants, where people tend to be in close quarters.
Most research has focused on coughing and sneezing. But studies on how simply breathing might contribute to airborne spread of the virus are rare.
Eating together as a family, maintaining the Mediterranean diet's traditional customs of conviviality, influences the eating habits of adolescents and prevents eating behaviour disorders, according to a new study prepared by scientists from the Universitat Oberta de Catalunya (UOC) and the Universitat Autònoma de Barcelona (UAB) and published in the open access International Journal of Environmental Research and Public Health.
Lakes act as an important part of the earth system. They have special functions in regulating regional climate and maintaining regional ecological balance. More than 39.2% of the lakes in China are distributed in the plateau. The topography around the plateau lake area is complex and diverse. It leads to a complex and unique local circulation characterized by the superposition of lake-land breeze circulation and mountain-valley breeze circulation, which has a significant impact on the local energy and material circulation, according to Prof.
The Tibetan Plateau, known as "the roof of the world", has warmed more rapidly than global average in the past decades. The observed warming of the Tibetan Plateau since 1960s can be attributed to human activities, particularly greenhouse gas emissions. Moreover, the Plateau may warm faster in the future than climate models projected, according to a study recently published in Environmental Research Letters.
Is there a way to chemically manipulate small, confined areas on cellular surfaces? Scientists have developed a microfluidic probe to send a flow of free radicals on live cells and track the outcome using fluorescence imaging. As outlined in the journal Angewandte Chemie, this approach makes it possible for the first time to generate a reaction zone of free radicals with controlled size and concentration for subcellular research.
Amsterdam, April 6, 2021 - The rarity of spinal muscular atrophy (SMA) means that promising new treatments may be tested in only a limited spectrum of patients before approval. Investigators evaluated a newly approved drug, onasemnogene abeparvovec, in a broader spectrum of patients in order to obtain expanded data on its side effects profile.
Innovation and advances in technology have facilitated agricultural activity in recent years, as traditional irrigation techniques have been supplanted by pressure-basedones, improving water efficiency but increasing energy dependence. This drives up the Agriculture sector's energy costs, some of the highest in the European Union.
It is difficult to imagine our daily life without lithium-ion batteries. They dominate the small format battery market for portable electronic devices, and are also commonly used in electric vehicles. At the same time, lithium-ion batteries have a number of serious issues, including: a potential fire hazard and performance loss at cold temperatures; as well as a considerable environmental impact of spent battery disposal.
Ambient air pollution is a global public health crisis, causing more than 4.9 million premature deaths per year around the world. In Africa, it has surpassed AIDS as the leading cause of premature death. According to one study, air pollution--specifically, fine particulate matter (PM2.5)--may cause at least as many as 780,000 premature deaths annually in Africa and worsen a significant number of diseases, including asthma, lung cancer, and chronic obstructive pulmonary disease.
With over 70% of respondents to a AAA annual survey on autonomous driving reporting they would fear being in a fully self-driving car, makers like Tesla may be back to the drawing board before rolling out fully autonomous self-driving systems. But new research from Northwestern University shows us we may be better off putting fruit flies behind the wheel instead of robots.
