Stroke-related deaths increased during the first lockdown Deaths of people who suffered strokes increased during the first lockdown compared to the three previous years, new data analysis has found. Despite the pandemic, health care quality was maintained at a high level. In their paper, published today in Stroke American Heart Association, research teams from King's College London, Guy's and St Thomas' NHS Foundation and the Sentinel Stroke National Audit Programme (SSNAP) analyzed the data of 184,017 patients admitted to hospital with confirmed stroke during October-April periods across fo...

Studies suggest mRNA COVID-19 vaccine may have reduced efficacy in patients with blood cancer Two new studies published in Blood suggest that the mRNA COVID-19 vaccine may have reduced efficacy in individuals with chronic lymphocytic leukemia (CLL) and multiple myeloma, two types of blood cancer. According to researchers, these studies could help inform the ideal time for vaccination of these populations. Study suggests two-dose COVID-19 vaccine is less effective for people with CLL as compared to healthy controls The first study reports that people with CLL had markedly lower immune respons...

Solvation cages may lead to more efficient operation of high-voltage battery cells Membranes that allow certain molecules to quickly pass through while blocking others are key enablers for energy technologies from batteries and fuel cells to resource refinement and water purification. For example, membranes in a battery separating the two terminals help to prevent short circuits, while also allowing the transport of charged particles, or ions, needed to maintain the flow of electricity. The most selective membranes - those with very specific criteria for what may pass through - suffer from lo...

Eco-Friendly Pollen Sponge can Help Overcome Marine Oil Spills Written by AZoMApr 8 2021 A research team, headed by Nanyang Technological University, Singapore (NTU Singapore) has produced a biodegradable, reusable sponge that can instantly absorb various organic solvents, including oil, from polluted water sources. This feature makes it a potential alternative for dealing with marine oil spills. Image Credit: ohrim/shutterstock.com   The sponge is composed of sunflower pollen and is hydrophobic, which means it repels water and this feature can be attributed to a layer of natural fatty acid...

Tibetan Plateau may Warm Faster in Future than Projected by Climate Models Written by AZoCleantechApr 7 2021 Over the last few decades, the Tibetan Plateau, called 'the roof of the world,' has warmed up more quickly compared to the global average. Projected future warming of the Tibetan Plateau in the CMIP5 ensemble. The thick curves indicate the multi-model ensemble means and the shadings denote the 90% model intervals, derived from the raw model output. The dashed curves indicate the constrained projections based on the attribution result. Blue and red represent a medium (RCP4.5) and high ...
