A healthy microbiome builds a strong immune system that could help defeat COVID-19

Ana Maldonado-Contreras, University of Massachusetts Medical School

Takeaways

  • Your gut is home to trillions of bacteria that are vital for keeping you healthy.
  • Some of these microbes help to regulate the immune system.
  • New research, which has not yet been peer reviewed, shows the presence of certain bacteria in the gut may reveal which people are more vulnerable to a more severe case of COVID-19.

You may not know it, but you have an army of microbes living inside of you that are essential for fighting off threats, including the virus that causes COVID-19.

Anti-nutrients – they’re part of a normal diet and not as scary as they sound

Jill Joyce, Oklahoma State University

Maybe you’re trying to eat healthier these days, aiming to get enough of the good stuff and limit the less-good stuff. You’re paying attention to things like fiber and fat and vitamins… and anti-nutrients?

What the heck are anti-nutrients and are they something you need to be concerned about in your diet?

Vaccines against SARS-CoV-2 will have side effects – that’s a good thing

Matthew Woodruff, Emory University

Takeaways

  • Temporary side effects from vaccines are a normal sign of a developing immune response.
  • Vaccines work by training your immune system to recognize and remember a pathogen in a safe way.
  • Expected side effects from a COVID-19 vaccine include redness and swelling at the injection site and stiffness and soreness in the muscle.
  • A potent vaccine may even cause fever. It does not mean that the vaccine gave you COVID-19.

In 2021 hundreds of millions of people will be vaccinated against SARS-CoV-2. The success of that COVID-19 vaccination campaign will heavily depend on public trust that the vaccines are not only effective, but also safe. To build that trust, the medical and scientific communities have a responsibility to engage in difficult discussions with the public about the significant fraction of people who will experience temporary side effects from these vaccines.

The Sunburst hack was massive and devastating – 5 observations from a cybersecurity expert

Paulo Shakarian, Arizona State University

So much remains unknown about what is now being called the Sunburst hack, the cyberattack against U.S. government agencies and corporations. U.S. officials widely believe that Russian state-sponsored hackers are responsible.

The attack gave the perpetrators access to numerous key American business and government organizations. The immediate effects will be difficult to judge, and a complete accounting of the damage is unlikely. However, the nature of the affected organizations alone makes it clear that this is perhaps the most consequential cyberattack against the U.S. to date.

Python skin jackets and elephant leather boots: How wealthy Western nations drive the global wildlife trade

Maria Ivanova, University of Massachusetts Boston and Candace Famiglietti, University of Massachusetts Boston

Three-quarters of new and emerging infectious diseases in humans originate in wildlife. COVID-19, SARS and Ebola all started this way. The COVID-19 global pandemic has drawn new attention to how people think about wild animals, consume them and interact with them, and how those interactions can affect public health.

Exercise leads to immune system boost

These at-home exercises can help older people boost their immune system and overall health in the age of COVID-19

Mark A. Gluck, Rutgers University – Newark ; Bernadette A. Fausto, Rutgers University – Newark , and Lisa Charles, Rutgers University – Newark

Older adults, especially those over 65, have five times the risk of hospitalization and 90 times the risk of death from COVID-19 compared with younger adults.

According to the U.S. Centers for Disease Control and Prevention, 78% of the more than 114,000 COVID-19 related deaths between May and August 2020 were people age 65 and older. Many of those individuals had compromised immune systems due, in part, to a variety of other health conditions including obesity, cardiovascular disease, diabetes, respiratory disease and hypertension. The CDC suggests these additional health problems could lead to increased severity of COVID-19.

Viruses evolve defenses, this allows them to adapt and could undermine a COVID-19 vaccine – but this can be stopped

Andrew Read, Penn State and David Kennedy, Penn State

The first drug against HIV brought dying patients back from the brink. But as excited doctors raced to get the miracle drug to new patients, the miracle melted away. In each and every patient, the drug only worked for a while.

Eating fish can provide powerful advantages for the heart and brain, yet Americans eat less than half of the 26 pounds per year that experts recommend. By contrast, Americans buy seven times more chicken and beef annually than fish.

COVID-19 reveals how obesity harms the body in real time, not just over a lifetime

Cate Varney, University of Virginia

The COVID-19 pandemic has thrust the obesity epidemic once again into the spotlight, revealing that obesity is no longer a disease that harms just in the long run but one that can have acutely devastating effects. New studies and information confirm doctors’ suspicion that this virus takes advantage of a disease that our current U.S. health care system is unable to get under control.

How the internet is changing the way we grieve

Social media has become a powerful platform to cope with grief.

Loss and grieving during the era of social media

Jo Bell, University of Hull

People don’t die in the same way that they used to. In the past, a relative, friend, partner would pass away, and in time, all that would be left would be memories and a collection of photographs. These days the dead are now forever present online and digital encounters with someone who has passed away are becoming a common experience.
