CORBEVAX, a new patent-free COVID-19 vaccine, could be a pandemic game changer globally

Maureen Ferran, Rochester Institute of Technology

The world now has a new COVID-19 vaccine in its arsenal, and at a fraction of the cost per dose.

Two years into the COVID-19 pandemic, the world has seen over 314 million infections and over 5.5 million deaths worldwide. Approximately 60% of the world population has received at least one dose of a COVID-19 vaccine. But there is still a glaring and alarming gap in global access to these vaccines. As a virologist who has followed this pandemic closely, I contend that this vaccine inequity should be of grave concern to everyone.

Removing greenhouse gases from the air

These machines scrub greenhouse gases from the air – an inventor of direct air capture technology shows how it works

Klaus Lackner, Arizona State University

Two centuries of burning fossil fuels has put more carbon dioxide, a powerful greenhouse gas, into the atmosphere than nature can remove. As that CO2 builds up, it traps excess heat near Earth’s surface, causing global warming. There is so much CO2 in the atmosphere now that most scenarios show ending emissions alone won’t be enough to stabilize the climate – humanity will also have to remove CO2 from the air.

Myocarditis: COVID-19 is a much bigger risk to the heart than vaccination

The heart has played a central role in COVID-19 since the beginning. Cardiovascular conditions are among the highest risk factors for hospitalization. A significant number of patients hospitalized with SARS-CoV-2 infections have signs of heart damage, and many recover from infection with lasting cardiovascular injury.

Sugar detox? Cutting carbs? A doctor explains why you should keep fruit on the menu

One of my patients – who had been struggling with obesity, uncontrolled diabetes and the cost of her medications – agreed in June 2019 to adopt a more whole-food plant-based diet.

Excited by the challenge, she did a remarkable job. She increased her fresh fruit and vegetable intake, stopped eating candy, cookies and cakes and cut down on foods from animal sources. Over six months, she lost 19 pounds and her HbA1c – a measure of her average blood sugar – dropped from 11.5% to 7.6%.

  • A large nationwide study identified inexpensive interventions that boosted weekly gym visits by up to 27%.
  • The results point to affordable strategies to help increase the amount of exercise Americans get on a regular basis.

Kids shouldn’t eat added sugar before they turn 2

A nutritional epidemiologist explains why kids shouldn’t eat added sugar before they turn 2.

Lisa Bodnar, University of Pittsburgh Health Sciences

I remember a decade ago sitting in front of my 9-month-old daughter, who was in her high chair, and trying to spoon-feed her a pureed green vegetable. It didn’t matter if it was peas, green beans or something else, because the outcome was the same: I spooned it into her mouth, and it came right back out.

Compare this with feeding her applesauce, for which she would open her mouth after each bite and almost bounce in her chair with pleasure. I nearly danced along with her. This was easier! Let’s just keep doing this! But as a nutritional epidemiologist, I knew that solely satisfying her desire for sweetness would not benefit her health in the long run.

How effective are vaccines against omicron?

An epidemiologist answers 6 questions about vaccine effectiveness against Omicron

Melissa Hawkins, American University

The pandemic has brought many tricky terms and ideas from epidemiology into everyone’s lives. Two particularly complicated concepts are vaccine efficacy and effectiveness. These are not the same thing. And as time goes on and new variants like omicron emerge, they are changing, too. Melissa Hawkins is an epidemiologist and public health researcher at American University. She explains the way researchers calculate how well a vaccine prevents disease, what influences these numbers and how omicron is changing things.

Global warming affecting western and eastern states differently

California is set to get its first significant soaking of the season this week, with forecasters predicting up to 7 inches of rain is possible in some parched parts of the state. On Tuesday, Oct. 19, 2021, state water officials said the rain could be enough to lessen some water restrictions imposed on farmers earlier this year, though it won’t be enough to catch California up on all the water is lost this summer.

2021’s climate disasters revealed an east-west weather divide, with one side of the country too wet, the other dangerously dry

Shuang-Ye Wu, University of Dayton

Alongside a lingering global pandemic, the year 2021 was filled with climate disasters, some so intense they surprised even the scientists who study them.

Extreme rainstorms turned to raging flash floods that swept through mountain towns in Europe, killing over 200 people. Across Asia, excessive rainfall inundated wide areas and flooded subway stations in China. Heat waves shattered records in the Pacific Northwest, Europe and the Arctic. Wildfires swept through communities in California, Canada, Greece and Australia. And those were only a few of the extremes.

Stress is contagious in relationships

Here’s what you can do to support your partner and boost your own health during the holidays and beyond

Rosie Shrout, Purdue University

With the flurry of shopping, spending money and traveling to see family, stress can feel inevitable during the holidays.

You might already know stress can affect your own health, but what you may not realize is that your stress – and how you manage it – is catching. Your stress can spread around, particularly to your loved ones.

Cognitive Decline – Risk Factors

Risk factors that determine whether you’re more or less likely to develop cognitive decline

Mark Dallas, University of Reading

About two in ten people over the age of 65 have mild cognitive impairment – a noticeable change in their memory, problem-solving abilities or attention. This is caused, in part, by the same brain changes that occur in dementia. While mild cognitive impairment often has little effect on a person’s way of living, 5-10% of people with it will develop dementia.
