36 dwarf galaxies had simultaneous 'baby boom' of new stars

Ever since the existence of molecules was proven and molecular reactions were predicted, humans have wanted to visually observe how such events proceed. Such observations of single-molecule reactions are highly important for the fundamental understanding of chemical sciences, which would aid in the development of novel catalysts, materials, or drugs, and help us decipher the complex biochemical processes. However, this was not possible for the longest time in modern chemistry, and so far the information of dynamical processes on the nanometer scale was obtained only from indirect methods because molecules ...

Healthcare and aerospace experts at King's College London, The Alan Turing Institute, the University of Cambridge, and the Oden Institute for Computational Engineering and Sciences at UT Austin in Texas have said advances in digital twin technology make it a powerful tool for facilitating predictive and precision medicine and enhancing decision-making for aerospace systems. Their opinion piece was published today in Nature Computational Science. When applied to healthcare, the digital twin, a virtual version of real-life objects that can be used to predict how that object will perform, could predict how a patient's disease will develop and how patients are likely to respond to different therapies. It is also of huge benefit in aerospace, where, for example, the technology ...

Climate change impacts felt in the Amazon rainforest prior to the arrival of European settlers after 1492 may have meant populations of indigenous people were already in decline before the 'Great Dying', new research has suggested. Scientists studying fossil pollen and charcoal data from across the Amazon say it appears to show that human management of the rainforest may have peaked around 1200 AD, before some sites were abandoned, allowing reforestation of these areas. The new research, involving University of Reading scientists and published in the journal Science, challenges the prior assumption that the largest population decrease in the Americas - known as the Great Dying - did not start until after European settlers carried new diseases to ...

Thermoelectric (TE) conversion offers a carbon-free power generation from geothermal, waste, body or solar heat, and shows promise to be the next-generation energy conversion technology. At the core of such TE conversion, there lies an all solid-state thermoelectric device which enables energy conversion without the emission of noise, vibrations, or pollutants. To this, a POSTECH research team proposed a way to design the next-generation thermoelectric device that exhibits remarkably simple manufacturing process and structure compared to the conventional ones, while displaying ...

CORVALLIS, Ore. - Two species of sand-stabilizing beachgrasses introduced to the Pacific Northwest starting in the early 1900s are hybridizing, raising new questions about impacts to the coastal ecosystems the non-native plants have been engineering for more than a century. Researchers in the Oregon State University College of Science identified the hybrid in a paper published in Ecosphere. In addition to their ecological implications, the findings are important in the context of coastal vulnerability to the effects of climate change, including increasing ...

Ibaraki, Japan - Ascending thoracic aortic aneurisms (aTAAs) occur when the walls of the aorta, the largest blood vessel in the body, weaken and begin to bulge. This can result in rupture or dissection (a tear in the aortic wall), leading to life-threatening bleeding and death. Sometimes these complications can occur before any symptoms of the aneurysm appear. However, an international team led by Hiromi Yanagisawa at the University of Tsukuba and Katja Schenke-Layland at Eberhard Karls University, Tübingen have used Raman microspectroscopy (an analysis technique that uses Raman scattering to probe ...

"If you build it, they will come," so says the idiom but it's the storytellers, knowledge-makers and an "agentic" or open-minded population who help create great entrepreneurial cities. A new research study, conducted by QUT, RMIT and the University of Indiana, analysed data from 362 American cities with a focus on human agency, entrepreneurial spirit, and economic growth. The study, based on geographic psychological profiles of millions of people based in the US, found people and an empowered city life matter in shaping urban vitality. The research points to San Francisco and Austin as the zip codes that drive the highest-impact ...

Feeling anxious can direct our attention and memory toward supernatural beings such as gods, a University of Otago study has found. Lead author Dr Thomas Swan, of the Department of Psychology, says the research may help explain how religious beliefs are formed. For the study, published in the International Journal for the Psychology of Religion, 972 participants completed an online recall test to determine if a bias to recall supernatural agents was stronger in anxious people, rather than non-anxious people. Those who felt anxious were more likely ...

Scientists are investigating whether rising global temperatures may lead to more stillbirths, saying further study is needed on the subject as climates change. Researchers from The University of Queensland's School of Earth and Environmental Science and the Mater Research Institute reviewed 12 studies, finding extreme ambient temperature exposures throughout pregnancy appeared to increase risk of stillbirth, particularly late in pregnancy. UQ PhD candidate Jessica Sexton said while this was very early research, it did show a possible link between stillbirth and high and low ambient temperature exposures during pregnancy. "Overall, risk of stillbirth appears ...

DALLAS, Sunday, May 23, 2021 - Late last week, the U.S. Centers for Disease Control and Prevention (CDC) alerted health care professionals that they are monitoring the Vaccine Adverse Events Reporting System (VAERS) and the Vaccine Safety Datalink (VSD) for cases of young adults developing the rare heart-related complication myocarditis, after receiving a COVID-19 vaccine manufactured by Pfizer-BioNTech or Moderna. The COVID-19 Vaccine Safety Technical Work Group (VaST) of the CDC's Advisory Committee on Immunization Practices (ACIP) is reviewing several dozen cases of myocarditis that ...
