For 17 years, cicadas do very little. They hang out in the ground, sucking sugar out of tree roots. Then, following this absurdly long hibernation, they emerge from the ground, sprout wings, make a ton of noise, have sex, and die within a few weeks. Their orphan progeny will then return to the ground and…
In the US, the first two available Covid-19 vaccines were those from Pfizer/BioNTech and Moderna. Both vaccines have very high “efficacy rates” of around 95 percent. But the third vaccine introduced in the US, from Johnson & Johnson, has a much lower efficacy rate: just 66 percent. Click Here: Look at those numbers next to…
Imagine you’re a scientist who needs to discover a new antibiotic to fight off a scary disease. How would you go about finding it? Typically, you’d have to test lots and lots of different molecules in the lab until you find one that has the necessary bacteria-killing properties. You might find some contenders that are…
This winter is brutal. The cold weather has made it hard to socialize outdoors, coronavirus variants are spreading, and the US is about to surpass half a million Covid-19 deaths. Many of us are feeling anxious about how we’re going to make it through the lonely, bleak weeks ahead. I see a lot of people…
We’ve reached half a million deaths from the coronavirus in the US. But most of these deaths — and the grueling medical ordeals leading up to them — have remained largely hidden from view. The majority of terminally ill Covid-19 patients typically spend their last days or weeks isolated in ICUs to keep the virus…
The power was still out in my Dallas housing complex early last Tuesday, so I grabbed the survival hatchet from my emergency bag to chop up a couple of fallen trees, which were covered with six inches of down-soft snow dropped by Winter Storm Uri. Click Here: The trees broke easily, and after 30 minutes…
When Hilda Bastian and I first caught up over Skype to talk about Covid-19 vaccines last autumn, she showed me the boxes and unfinished rooms in her new home in Victoria, Australia. She’d been so busy tracking the global vaccine effort, she hadn’t had time to settle in. Bastian — an expert in analyzing clinical…
The world is now locked in an arms race with Covid-19, as multiple effective vaccines are being deployed (at staggeringly different rates) around the world. At the same time, new variants of the SARS-CoV-2 virus have been rapidly spreading. The Covid-19 vaccines that are being distributed in the US, as well as the newly authorized…
One big reason to be excited about the new Johnson & Johnson vaccine for Covid-19, which was authorized by the Food and Drug Administration over the weekend for emergency use in the US: Unlike the Moderna and Pfizer vaccines already in use, it requires only one shot for full protection. That’s a big deal. From…
When many Americans talk about returning to “normal life” after the pandemic, they might mean going back to the office, resuming in-person school or child care, or preparing for the best summer ever. For plenty of other people, though, their true barometer is the simple ability to once again eat indoors at restaurants. The past…
