Researchers concluded that fine respiratory aerosols may play a significant role in SARS-CoV-2 transmission, especially in an indoor environment, and hence, should be taken into consideration when planning infection prevention measures. |
| Future battery cost: Crucial for the success of the mobility and energy transition Posted: 11 Aug 2021 10:12 AM PDT A group of researchers has published a comparative study of battery cost predictions from the past decade. In the study, assumptions from more than 50 scientific publications that analyze the costs of lithium-ion, solid-state, lithium-sulfur and lithium-air batteries, resulting costs are compared and the academic opinion is consolidated into a cost trend. |
| A clean US hydrogen economy is within reach, but needs a game plan, energy researchers say Posted: 11 Aug 2021 08:31 AM PDT Addressing climate change requires not only a clean electrical grid, but also a clean fuel to reduce emissions from industrial heat, long-haul heavy transportation, and long-duration energy storage. Hydrogen and its derivatives could be that fuel, argues a recent commentary , but a clean U.S. H2 economy will require a comprehensive strategy and a 10-year plan. The commentary suggests that careful consideration of future H2 infrastructure, including production, transport, storage, use, and economic viability, will be critical to the success of efforts aimed at making clean H2 viable on a societal scale. |
| Science alone won’t save humpback dolphins Posted: 11 Aug 2021 08:31 AM PDT There are fewer than 500 Indian Ocean humpback dolphins (Sousa plumbea) remaining in South African waters. Science alone will not bring them back from the brink of extinction -- we also need a multi-stakeholder Conservation Management Plan to boost their numbers. This is according to research focusing on the conservation status of the little-known humpback dolphin which can be found along the south and east coast from False Bay to Kosi Bay. |
| Global eradication of COVID-19 should not be dismissed, new analysis finds Posted: 11 Aug 2021 06:15 AM PDT Eradicating COVID-19 across the globe is theoretically more feasible than for polio but much less so than it was for smallpox, according to an analysis by New Zealand researchers. |
| What to call seafood made from fish cells Posted: 09 Aug 2021 11:40 AM PDT Food companies, regulators, marketers, journalists and others should use the terms 'cell-based' or 'cell-cultured' when labeling and talking about seafood products made from the cells of fish or shellfish, according to a new study. |
| Crowding in prisons increases inmates' risk for COVID-19 infections, study finds Posted: 09 Aug 2021 08:28 AM PDT Earlier research indicated that prison inmates have a significantly higher risk for COVID-19 infections compared to the general population. A new study offers powerful evidence that facility crowding is a major driver of this increased risk. Policy changes aimed at reducing prison populations could minimize this threat. |
| Youth, the pandemic and a global mental health crisis Posted: 09 Aug 2021 08:28 AM PDT An alarming percentage of children and adolescents are experiencing a global-wide mental crisis due to the COVID-19 pandemic according to a new study. |
