“…Artificial neural networks (ANNs) have undergone a revolution, catalyzed by better supervised learning algorithms. However, in stark contrast to young animals (including humans), training such networks requires enormous numbers of labeled examples, leading to the belief that animals must rely instead mainly on unsupervised learning. …”

“…Investigators are employing unprecedented innovation in the design of clinical trials to rapidly and rigorously assess potentially promising therapies for coronavirus disease 2019 (COVID-19); this is in stark contrast to the continued near-universal regressive practice of exclusion of pregnant and breastfeeding women from these trials. …”

“…Here, by conducting in situ transmission electron microscopy (TEM) at atomic scale, we discover that, in stark contrast to those in most Fcc metals, a majority of deformation twins in Bcc metals are unstable and undergo spontaneously detwinning upon unloading. …”

“…The cosmological constant, also known as dark energy, was believed to be caused by vacuum fluctuations, but naive calculations give results in stark disagreement with fact. In the Casimir effect, vacuum fluctuations cause forces in dielectric media, which is very well described by Lifshitz theory. …”

“…Yet many challenges remain, including a lack of substantial new financial investments from governments, ongoing human rights abuses suffered by people living with mental illness, weak health systems in low resource settings and large gaps in our knowledge regarding aetiology, prevention of mental illness and mental health promotion. Stark inequalities persist between high-income countries and low- and middle-income countries (LMIC) in research knowledge and service resources. …”

“…Such a system, depending on the nanostar concentration, can form either equilibrium or phase separation gels. In stark contrast to the heterogeneity of concentration and dynamics displayed by the phase separation gel, the equilibrium gel shows absence of aging and a remarkable spatially uniform dynamics.…”

“…This disparity points to the question of why inequities in maternal healthcare exist and, of critical importance, what is being done to combat them. The stark reality is that systemic racism is at the core of these health disparities and must be addressed by both the individuals providing care and the healthcare systems themselves. …”
