In an in-depth study of how COVID-19 affects a patient's brain, National Institutes of Health researchers consistently spotted hallmarks of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after contracting the disease. In addition, they saw no signs of SARS-CoV-2 in the tissue samples, suggesting the damage was not caused by a direct viral attack on the brain. The results were published as a correspondence in the New England Journal of Medicine.

Higher red cell transfusion threshold offers no advantage for treating preterm infants

Very low birthweight infants often need blood transfusions to survive. A National Institutes of Health-funded study suggests that providing a higher threshold of red cells within accepted limits offers no advantage in survival or reduction in neurological impairment over a lower threshold. The research was conducted by Haresh Kirpalani, B.M., of the University of Pennsylvania, Philadelphia, and colleagues and was funded by the NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Heart, Lung, and Blood Institute, and National Center for Advancing Translational Sciences. The study appears in The New England Journal of Medicine.

Designing Dirac vortex topological photonic crystal fibres

Optical fibres made of topological photonic crystals allow improved versatility and control across the modes and polarization of light they transmit. Compositionally, photonic crystals contain bandgaps to prevent the passage of light relative to specific wave energies and momenta much like an on/off switch. In a new report now published on Nature Light: Science & Applications, Hao Lin, and Ling Lu at the Institute of Physics at the Chinese Academy of Sciences transmitted pure "single mode" light across a large frequency range via a topological feature known as a "Dirac vortex." The concept can lead to applications that transmit light signals more stably across long distances. While the work is theoretical at present, the researchers suggest the use of fibers made from silica based on stack-and-draw methods or three-dimensional (3-D) printing technologies to fabricate and test these theoretical concepts.

Grid or solar: looking for the best energy solution for the rural poor

South Asia has made tremendous progress in connecting rural areas to the electricity grid but the number of people in Africa without access has scarcely changed since 2010. More than a half-billion people in Africa don't have access to electricity, meaning the continent hosts 72% of the world's non-electrified population. The UN Sustainable Development Goals have set a universal goal of ensuring access to affordable, reliable, sustainable and modern energy for all by 2030. To achieve this, the continent will require a big electrification push.
