Covid-19: What Are The New Variants & How Are They Monitored (Podcast)
Over the course of the pandemic, scientists have been monitoring emerging genetic changes to Sars-Cov-2. Mutations occur naturally as the virus replicates but if they confer an advantage – like being more transmissible – that variant of the virus may go on to proliferate.
This was the case with the ‘UK’ or B117 variant, which is about 50% more contagious and is rapidly spreading around the country. So how does genetic surveillance of the virus work? And what do we know about the new variants? Ian Sample speaks to Dr Jeffrey Barrett, the director of the Covid-19 genomics initiative at the Wellcome Sanger Institute, to find out Coronavirus – latest updates See all our coronavirus coverage.

Health: ‘Top Five Diets’ Ranked – “Keep It Simple”
Every year, as millions of people around the world forge new resolutions to eat healthier and lose weight, US News & World Report releases a conveniently timed ranking of the best diets. A panel of experts in obesity, nutrition, diabetes, heart disease, and food psychology rigorously rate each of 39 diets on seven criteria:
- Likelihood of losing significant weight in the first 12 months
- Likelihood of losing significant weight over two years or more
- Effectiveness for preventing diabetes (or as a maintenance diet)
- Effectiveness for preventing heart disease (or for reducing risk for heart patients)
- How easy it is to follow
- Nutritional completeness
- Health risks (like malnourishment, too-rapid weight loss, or specific nutrient deficiencies)
1. Mediterranean diet
Emphasis on fruits, veggies, whole grains, olive oil, beans, nuts, legumes, fish and other seafood. Eggs, cheese, and yogurt can be eaten in moderation. Keep red meats and sugar as treats.
2. DASH (dietary approaches to stop hypertension) diet — TIE
Eat lots of fruits, veggies, lean protein, whole grains, and low-fat dairy. Avoid saturated fats and sugar.
2. Flexitarian diet — TIE
Be a vegetarian most of the time. Swap in beans, peas, or eggs for meats, and consume plenty of fruits, veggies, and whole grains. You can look up more details because there’s actually a full meal plan involving breakfast, lunch, dinner, and two snacks to add up to a total 1500 calories per day. But feel free to also just swap in flexitarian meals ad hoc.
4. Weight Watchers
The first actual paid program on the list, WW uses a points system to guide dieters towards foods lower in sugar, saturated fat, and overall calories while consuming slightly more protein. There are a variety of paid WW plans, with the lowest being about $20 per month.
5. Mayo Clinic diet — TIE
A two-part system, with part one (‘Lose it!’) involving adding a healthy breakfast (i.e. fruits, veggies, whole grains, healthy fats) plus 30 minutes of exercise per day. You’re not allowed to eat while watching TV or consume sugar except what’s naturally found in fruit. Meat is only allowed in limited quantities, as is full-fat dairy. The second phase (‘Live it!’) is basically the first phase but with more flexibility. You aren’t realistically going to cut out sugar forever, and the Mayo Clinic diet acknowledges that. So the long term plan involves lots of whole grains, fruits, veggies, and healthy fats. Less saturated fats and sugar.
