Millions of people around the world have been left managing the complex and amorphous syndrome that is long COVID. But the underlying cause of this myriad of symptoms is not clear. One hypothesis is that the virus is able to find a safe haven in the body from which it can bide its time and potentially re-emerge - a viral reservoir. Now researchers studying long COVID have found evidence of SARS-CoV-2 in a series of organs around the body, most notably the gut, months after the infection appears ...

00:57 Reviving retinas to understand eyes Research efforts to learn more about diseases of the human eye have been hampered as these organs degrade rapidly after death, and animal eyes are quite different to those from humans. To address this, a team have developed a new method to revive retinas taken from donors shortly after their death. They hope this will provide tissue for new studies looking into the workings of the human eye and nervous system. Research article: Abbas et al. 08:05 Researc...

The true disability cost of the COVID-19 pandemic is still unknown, but more and more studies are adding to the list of potential fallout from even mild COVID 19 infection. In this episode of Coronapod we discuss a massive association study which links COVID-19 cases with an increase in the risk of developing type 2 diabetes. We delve into the numbers to ask how big the risk might be? Whether any casual relationship can be drawn from this association? And what might be in store from future resea...

00:56 How video calls can reduce creativity As a result of the pandemic, workers around the world have become accustomed to meeting colleagues online. To find out if this switch from face-to-face meetings came at a cost to creativity, a team compared the number of ideas generated by workers collaborating either online, or in-person. They showed that people meeting virtually produced fewer creative ideas than those working face-to-face, and suggest that when it comes to idea generation maybe it’s...

Results from a huge epidemiological study found that infection by the Epstein-Barr virus increases the risk of developing multiple sclerosis 32-fold. This result, combined with emerging mechanistic insights into how the virus triggers brain damage, are raising the prospect of treating or preventing MS. These advances come at a time when researchers are more interested than ever in what happens in the months and years following a viral infection, and highlights the issues untangling the relations...

Since the beginning of the pandemic there has been a debate amongst researchers about whether the body's immune cells can themselves be infected by SARS-CoV-2. Now two new studies show that they can - and what's more, the work has revealed a new mechanism for the massive inflammatory response seen in severe COVID. In this episode of Coronapod , we dig into the papers, asking why it has taken so long to get an answer to this question? How immune cell infection could lead to severe disease? And wh...

00:54 How Mammals’ mutation rates affects their lifespan For biologists, a long-standing question has been why some animals live longer than others. This week a team have attempted to answer this, by measuring the rates that different animal species accumulate mutations. They show that longer-lived animals acquire mutations at a slower rate, which helps to explain why cancer risk does not scale with lifespan. Research article: Cagan et al.

00:46 The very cool experiment looking for a proposed particle Physics tells us that when matter is created, antimatter should be as well. But while the Universe is full of matter, there’s surprisingly little antimatter to be found. To try and understand this imbalance, a team have built a detector kept just above absolute zero which they are using to look for a hypothesised, ultra-rare type of particle decay that could create matter without antimatter.

While current maps of the human genome provide researchers with a wealth of information, many argue that they do not adequately capture humanity’s vast diversity. Now, a team are trying to build a more complete and representative map that shows the varieties of sequence that can be found in different populations. However, given the failings of other projects, some geneticists focused on the needs of Indigenous communities are wary of the initiative. This is an audio version of our Feature: A mor...

A handful of states around the world have pursued 'COVID zero' strategies. Through a combination of intensive lockdowns, travel restrictions and comprehensive test and trace systems, regions like Tonga, New Zealand, Taiwan, mainland China and Western Australia managed to keep the virus at bay. But now many of these countries are facing new outbreaks on a scale they have not yet seen, and it is being driven in part by vaccine hesitancy. In this episode of Coronapod we discuss how a successful pub...

As many countries start to ease or even remove COVID restrictions entirely, there are growing concerns from researchers that this will lead governments to take their eye off the ball and crucially stop collecting and reporting vital data. In this episode of Coronapod we discuss calls from two researchers to improve COVID testing and data reporting. What do they want done differently? Why does it matter? And what could such changes mean for the future of the pandemic and public health more broadl...

Almost everything we do on the Internet is made possible by cryptographic algorithms, which scramble our data to protect our privacy. However, this privacy could be under threat. If quantum computers reach their potential these machines could crack current encryption systems — leaving our online data vulnerable. To limit the damage of this so called 'Q-day', researchers are racing to develop new cryptographic systems, capable of withstanding a quantum attack. This is an audio version of our feat...

Vaccine inequity continues to be one of the greatest challenges in the pandemic - with only 10% of those in low- and middle-income countries fully vaccinated. One of the biggest hold-ups is a lack of vaccine manufacturing capacity in poorer nations. But now, researchers at the WHO technology-transfer hub have completed the first step in a project aimed at building vaccine manufacturing capacity in the Global South, by successfully replicating Moderna's COVID vaccine without assistance from the U...

Much of the coverage of COVID immunity often focuses on antibody response and for good reason - these small, y-shaped proteins can detect, and in some cases neutralise, viruses like SARS-CoV-2. But as variants like Omicron evolve to evade antibodies, the role of another part of the immune system, T cells, has been brought into sharper focus. These immune cells work in a different way to antibodies, attacking infected cells rather than the virus itself, which can make their response broader and m...

As of January 2022, the WHO reports that 5.5 million people have lost their lives to the pandemic. However, many research groups suggests that this number is likely to be a significant underestimate, although it is hard to be certain as counting mortality across the world is an exceptionally difficult task. In this episode of Coronapod we ask why, and delve into the range of approaches scientists are taking to try to get to the bottom of the sticky problem - from excess death counts, to machine ...
