‘Universal’ coronavirus vaccine may protect against variants, common cold

An experimental COVID-19 vaccine could potentially provide universal protection against future COVID-19 variants as well as other coronaviruses — maybe even the ones responsible for the common cold.

And it’s dirt cheap — less than $1 a dose, researchers say.

The vaccine targets a part of the COVID-19 virus’ spike protein that appears to be highly resistant to mutation and is common across nearly all coronaviruses, said senior researcher Dr. Steven Zeichner. He is a professor of pediatric infectious disease with the University of Virginia, in Charlottesville.

Fears of a Chinese attack on Taiwan are growing, and Taiwan isn’t sure who would help if it happened

This is especially daunting for Taiwan, as it is unclear whether it can get help from anyone else if, or when, the time comes.

In March, Adm. Philip Davidson, the head of US Indo-Pacific Command at the time, told the Senate Armed Services Committee that China could invade Taiwan in the next six years.

A few days later, Adm. John Aquilino, Davidson’s successor, declined to comment on that assessment but said China views Taiwan “as their No. 1 priority,” and that, in his opinion, “this problem is much closer to us than most think.”

EPA Moves To Cut A Group Of Powerful Greenhouse Gases

The EPA’s new regulation would slash HFC production, import and use, beginning in 2022. The agency said its goal is to reduce HFC production and import by 85% over the next 15 years.


The EPA plans to phase out hydrofluorocarbons, or HFCs, which are used in refrigerators and air conditioners. When HFCs are released into the atmosphere, they are extremely good at trapping heat.

The Cozy Mysteries of the Pacific Northwest

The Pacific Northwest is known for its spectacular views and dark and rainy beaches. There are deep green rainforests filled with redwoods and tall trees. With its miles and miles of hiking trails, it’s known for its mountains, the Columbia River Gorge, and Lewis and Clark’s expedition.

I think it’s also the perfect area for writers and mysteries—and that’s the reason why I set my latest cozy series along the Oregon Coast. I had the privilege of living in Oregon for two years and took multiple trips to the coast to enjoy the water, wildlife, and hiking.

In Death Bee Comes Her, the first installment in my new Oregon Honeycomb mysteries, Wren Johnson lives in a fictional coastal town that combines the charms of several of my favorite places to visit. The people there are quirky, smart, and from sturdy pioneer stock, from Wren’s Aunt Eloise, to loggers, surfers, and crab and whale boat operators.

Solar Wind Traveling 1,118,468 mph Due to Hit Earth Sunday

Just days after Earth was hit by a coronal mass ejection (CME), it appears another blast of solar wind is due to impact Earth on Sunday; it is currently traveling at a brisk 1118, 468 mph towards the planet.

A minor G1-class Geomagnetic Storm is possible late Saturday into much of Sunday as the solar wind interacts with the Earth’s magnetic field. While the National Weather Service’s Space Weather Prediction Center has not issued any advisory for this solar wind yet, a watch or warning could be posted tomorrow for this event.

Drone Swarms for Firefighting Future of Fire Suppression

Are drone swarms for firefighting the future of fire supression? New work from engineer and mathematician Elena Ausonio and a team of Italian researchers suggests that they could be.

The following is a guest post by Max Lenz, Executive Editor and project manager at the Berlin-based DroneMasters Boost GmbH and editor of the weekly DroneMasters Briefing. DRONELIFE neither makes nor accepts payment for guest posts.

Arabian cult may have built 1000 monuments older than Stonehenge

Made from piled-up blocks of sandstone, some of which weighed more than 500 kilograms, mustatils ranged from 20 metres to more than 600 metres in length, but their walls stood only 1.2 metres high. “It’s not designed to keep anything in, but to demarcate the space that is clearly an area that needs to be isolated,” says Thomas.

In a typical mustatil, long walls surround a central courtyard, with a distinctive rubble platform, or “head”, at one end and entryways at the opposite end. Some entrances were blocked by stones, suggesting they could have been decommissioned after use.

Excavations at one mustatil showed that the centre of the head contained a chamber within which there were fragments of cattle horns and skulls. The cattle fragments may have been presented as offerings, suggesting mustatils may have been used for rituals.
