But the findings haven’t yet been peer-reviewed, and experts caution that a vaccine is still a long way off. Researchers announced at an AIDS conference in February that 35 of the 36 people who received the new HIV vaccine produced antibodies that might help their immune systems to fend off infection. #Nuclear fission chernobyl trial#7 Wisps of hope for long-sought HIV vaccineįour decades after the start of the AIDS epidemic, results from a small clinical trial hint at some progress towards a vaccine that protects against HIV. Researchers are pushing the science of ocean forecasting forward, and are looking to develop tools that will help fisheries managers and policymakers respond to these painful symptoms of a warming world. A grim example was dubbed The Blob: an expanse of warm, low-nutrient water in the northwest Pacific that lasted for three years and decimated plankton, fish and seabird populations. #Nuclear fission chernobyl how to#Marine Heatwave Tracker (2020) How to predict deadly ocean heatwavesĭevastating marine heatwaves are ravaging ecosystems, bleaching coral and putting key fisheries at risk.

Fears of inequitable data use are amplified by the fact that only 0.3% of COVID-19 vaccines have gone to low-income countries. Critics say that getting rid of all restrictions on data sharing deprives contributors of credit and undermines their efforts - particularly for those in resource-limited countries. Some researchers are pushing back on calls to share SARS-CoV-2 genome sequences on fully open databases. Nature | 4 min read The downside of genome data sharing “First we need to remove patent obstacles, second we need to transfer the knowledge on how to make them, and step three is a massive investment in manufacturing capacity.” “It’s a 1-2-3,” explains Rachel Cohen, the US director for the non-profit organization Drugs and Neglected Diseases initiative. But a waiver on patents would be just the first step in ramping up vaccine supply. “This marks a major shift in US policy in a pro-public health way,” says global-health researcher Matthew Kavanagh. The measure is aimed at boosting supplies so that people around the world can get the shots. In a shock move, the US government has announced its support for waiving patent protections for COVID-19 vaccines.

In some countries, such as Australia and New Zealand, the response to potential threats is swift and severe - but this cannot be sustained indefinitely. The mechanism driving the reaction, how it might develop and how to suppress it are all open questions.Īs more people get vaccinated, scientists and health officials are pondering how societies can live with the virus and the level of risk that they are willing to take on. Entombed under concrete, the room contains some of the congealed lava that includes much of the reactor's uranium fuel. “It’s like the embers in a barbecue pit,” says nuclear-materials chemist Neil Hyatt. Rising levels of neutrons from an inaccessible room at Chernobyl Nuclear Power Plant indicate that fission reactions are smouldering again at the site of the 1986 disaster.

But back-to-back announcements from Roche and Wave Life Sciences have dealt a crushing blow to those affected by the disease. Researchers had hoped that the treatments - known as antisense oligonucleotides (ASOs) - would be a game changer for HD, an incurable genetic condition that affects cognition, behaviour and movement. Two pharmaceutical companies have halted clinical trials of gene-targeting therapies for Huntington’s disease (HD), following the drugs’ disappointing performance.
