BENGALURU/LONDON (Reuters) — The United States has secured almost a third of the first 1 billion doses planned for AstraZeneca’s experimental COVID-19 vaccine by pledging up to $1.2 billion, as world powers scramble for medicines to get their economies back to work.
While not yet proven to be effective against the coronavirus, vaccines are seen by world leaders as the only real way to restart their stalled economies, and even to get an edge over global competitors.
EMP weapons, streams of microwaves, electromagnetic railguns, and high-power lasers offer new ways to bring down swarming drones, sink ships without explosives, and disperse formations of soldiers.
NASA’s WFIRST mission will explore the universe, seeking answers to some of its biggest mysteries. From understanding the nature of dark energy to studying planets outside our solar system, this mission will expand our view of the cosmos. Join experts Wednesday, May 20 at 11 a.m. ET for an exciting announcement about the WFIRST mission.
Humans are living longer than ever before. But alongside these increases in life expectancy are an increase in the occurrence of age-related diseases such as cancer and dementia.
But understanding the biology of ageing, and knowing the genes and proteins involved in these processes, will help us increase our “healthspan”—the period that people can live in a healthy and productive state, without age-related diseases.
In a recent study, our team identified a novel anti-ageing protein, called Gaf1. We found that Gaf1 controls protein metabolism, a process that has been implicated in ageing and disease. We also found that without Gaf1, cells have a shorter lifespan.
The lessons from his presidency show that a quick retreat to the past can be just a mirage.
Studies of collective behavior usually focus on how crowds of organisms coordinate their actions. But what if the individuals that don’t participate have just as much to tell us?
The development of next-generation solar power technology that has potential to be used as a flexible ‘skin’ over hard surfaces has moved a step closer, thanks to a significant breakthrough at The University of Queensland.
UQ researchers set a world record for the conversion of solar energy to electricity via the use of tiny nanoparticles called ‘quantum dots’, which pass electrons between one another and generate electrical current when exposed to solar energy in a solar cell device.
The development represents a significant step towards making the technology commercially-viable and supporting global renewable energy targets.
Australian scientists have for the first time produced a new generation of experimental solar energy cells that pass strict International Electrotechnical Commission testing standards for heat and humidity.
The research findings, an important step towards commercial viability of perovskite solar cells, are published today in the journal Science.
Solar energy systems are now widespread in both industry and domestic housing. Most current systems rely on silicon to convert sunlight into useful energy.
NASA’s human spaceflight chief Doug Loverro has stepped down just a week ahead of a historic SpaceX crew launch for the U.S. space agency.
A study published in Current Biology reports on one of the first comprehensive characterizations of poorly formed memories, and may offer a framework to explore different therapeutic approaches to fear, memory and anxiety disorders. It may also have implications for accuracy of some witness testimony.
Senior author Professor Bryce Vissel, from the UTS Centre for Neuroscience & Regenerative Medicine, said his team used novel behavioral, molecular and computational techniques to investigate memories that have not been well-formed, and how the brain deals with them. “For memories to be useful, they have to have been well-formed during an event—that is, they have to accurately reflect what actually happened.
”However, in the real world many memories are likely to be inaccurate—especially in situations where the experience was brief, sudden or highly emotional, as can often occur during trauma. Inaccurate memories can also occur when the memory is poorly encoded, potentially as a result of subtle differences in how each person processes memory or because of disease like Alzheimer’s or dementia.”
