Wormholes play a key role in many science fiction films - often as a shortcut between two distant points in space. In physics, however, these tunnels in spacetime have remained purely hypothetical. An international team led by Dr. Jose Luis Blázquez-Salcedo of the University of Oldenburg has now presented a new theoretical model in the science journal Physical Review Letters that makes microscopic wormholes seem less far-fetched than in previous theories.
Delaying second doses of COVID-19 vaccines should reduce case numbers in the near term. But the longer-term case burden and the potential for evolution of viral "escape" from immunity will depend on the robustness of immune responses generated by natural infections and one or two vaccine doses, according to a Princeton University and McGill University study published March 9 in the journal Science.
Members of the COVID-19 Primary Care Database Consortium explain how the use of big data containing millions of primary care medical records provides an opportunity for rapid research to help inform patient care and policy decisions during the COVID-19 pandemic. Established in April 2020, the Consortium brings together experts in big data, epidemiology, intensive care, primary care and statistics, as well as journal editors, patient and public representatives, and front-line clinical staff from the universities of Oxford, Cambridge, Southampton, Bristol and Nottingham
Members of the Perelman School of Medicine at the University of Pennsylvania and its health system developed and implemented a new model of collaborative care called The Penn Integrated Care (PIC) program. PIC includes a resource center to support intake, triage and referral management and collaborative care services in primary care practices. PIC was created to increase access to and engagement with mental health professionals to improve mental and physical health outcomes. Primary care physicians were able to refer patients with any mental health symptom or condition to PIC.
RIVERSIDE, Calif. -- Variants of the coronavirus are appearing in different parts of the world, many of them spreading with alarming speed. One contagious variant is the South African, or SA, variant, identified by an international team of researchers, including biomedical scientists from the University of California, Riverside.
New study finds the skyrocketing cost of drugs in U.S. used to treat hookworm and other soil-transmitted parasites increases patient costs, suggests decreased quality of care
A research team at Johannes Gutenberg University Mainz (JGU) in Germany has developed a completely new, environmentally-friendly electrochemical procedure for producing sulfonamides rapidly and inexpensively. Sulfonamides are used in many drugs including antibiotics and Viagra as well as in agrochemicals and dyes, which makes them an important class of molecules for the pharmaceutical and chemical industries.
A new study led by the University of Portsmouth has identified that one of the major factors of age-related brain deterioration is the loss of a substance called myelin.
Myelin acts like the protective and insulating plastic casing around the electrical wires of the brain - called axons. Myelin is essential for superfast communication between nerve cells that lie behind the supercomputer power of the human brain.
MIAMI--In the Florida Straits at night, and under a new moon is the preference for spawning mahi-mahi, according to a new study by scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science.
These new details on the daily life of the highly sought-after migratory fish can help better manage their populations and provide scientists with new information to understand the impacts to the animal from changing environmental conditions.
Researchers from University of Texas-Arlington, University of Virginia, Sun Yat-Sen University, and University of Washington published a new paper in the Journal of Marketing that seeks to advance the discipline of avatar-based marketing.
The study, forthcoming in the Journal of Marketing, is titled "An Emerging Theory of Avatar Marketing" and is authored by Fred Miao, Irina Kozlenkova, Haizhong Wang, Tao Xie, and Robert Palmatier.
Armando Collazo Garcia III got more than he expected from a graduate course he took last spring. He developed a new understanding of the physics of transonic shocks produced across a laminar flow airfoil with boundary-layer suction and added a published paper to his resume.
Research from the University of Kent predicts an end to deregulated competitive public transport in the UK as a consequence of Covid-19 social distancing measures leading to drastically reduced ridership, requiring a major rethinking of the provision of public transport.
Researchers at Paderborn and Bielefeld University are hoping to change this, and are discussing how the explainability of artificial intelligence can be improved and adapted to the needs of human users. Their work has recently been published in the respected journal IEEE Transactions on Cognitive and Developmental Systems. The researchers describe explanation as a social practice, in which both parties co-construct the process of understanding.

In the EU alone, 78,800 men died of prostate cancer last year. While tumors discovered at an early stage can often be completely removed by surgery and radiation therapy, the prospects of successful treatment are reduced if the cancer has further metastasized. At present, physicians cannot predict drug response or therapy resistance in patients.

Tocilizumab cuts mortality risk in severely ill COVID-19 patients finds new trial conducted in India
Tocilizumab, an anti-inflammatory drug used to treat rheumatoid arthritis, improves outcomes in severely ill COVID-19 patients, finds the results of a new trial conducted in hospitals across India -- one of the world's most ethnically diverse countries. Researchers from the University of Bristol and Medanta Institute of Education and Research in India who led the study, published in The Lancet Respiratory Medicine, say it adds to existing evidence supporting the drug's use in critically ill patients.
