The virus that causes Covid-19 hijacks human cells by exploiting a ‘doorway’ that is potentially also used by other deadly viruses such as HIV, dengue and Ebola, according to recent research that may help to explain why the coronavirus is so highly infectious to a wide range of organs in the body. Dr Yohei Yamauchi, a viral cell biologist at the University of Bristol, UK, who led the research, believes that the finding could not only lead to new drugs against Covid-19, but other anti-viral treatments that could be used to save patients’ lives in future pandemics.
Our Milky Way is thought to be home to as many as 400 billion stars, one of which is, of course, our own sun. But how and when did these stars form, and where did they come from?
The world’s first mRNA vaccine has begun its rollout after being produced at unprecedented speed as part of the global effort to end the Covid-19 pandemic. A second one is hot on its heels. The two – one made by Pfizer/BioNTech and the other by Moderna – mark the first time this vaccine technology has been approved for use.
From wars to weddings, Europe’s history is stored in billions of archival pages across the continent. While many archives try to make their documents public, finding information in them remains a low-tech affair. Simple page scans do not offer the metadata such as dates, names, locations that often interest researchers. Copying this information for later use is also time-consuming.
Our Milky Way is not alone in the universe. Surrounding us are numerous satellite galaxies, taking part in a continuous grand dance. But how do these neighbouring galaxies behave, how do they interact with our galaxy, and what does the future hold for them?
As the social isolation compelled by the pandemic swept many of us into a flurry of panic, grief and mental funk, a section of people actually reported improved levels of wellbeing, found biological psychologist Meike Bartels, a professor of genetics and wellbeing at VU Amsterdam, the Netherlands.
In December, as the European Space Agency’s Gaia mission to create a precise 3-D map of a billion objects in the Milky Way releases its next tranche of data, we take an in-depth look at what we know – and what we don’t – about our home galaxy. We speak to astrophysicist Prof. Ralf Klessen about why it might enhance our understanding of the Milky Way to consider it as a constantly evolving ecosystem rather than studying different parts in an isolated way. We speak to scientists who are trying to image the centre of the galaxy, which is hidden from view behind giant dust and gas clouds, and we explore the latest research into how stars are formed. And finally, we find out what the galaxies surrounding the Milky Way can tell us about our home system.
The Milky Way might be right on our cosmic doorstep, but a group of astronomers suspect that the way we currently study it is stunting our understanding. Professor Ralf Klessen at Heidelberg University in Germany is one of four researchers who have recently begun a six-year project, ECOGAL, to try something new: imagine our home galaxy as one huge galactic ecosystem. Prof. Klessen believes that using this lens could answer fundamental questions about how stars and planets form, and how they shape the Milky Way’s future.
Imagine controlling your computer just by thinking. It sounds far-out, but real advances are happening on these so-called brain-computer interfaces. More researchers and companies are moving into the area. Yet major challenges remain, from user training to the reality of invasive brain implant procedures.
Artificial intelligence is growing ever more powerful and entering people’s daily lives, yet often we don’t know what goes on inside these systems. Their non-transparency could fuel practical problems, or even racism, which is why researchers increasingly want to open this ‘black box’ and make AI explainable.
Producers must act now to ensure survival, say experts.
In-depth knowledge of supply chains and pre-certification scheme could reduce medical supply disruption.
