Antibiotics won't help with COVID-19 because the disease is not caused by bacteria but instead a virus. However, a new study finds that some antibiotics can prevent the entry of the SARS-CoV-2 virus into cells. The Drug Design and Molecular Topology Unit group of the University of Valencia found that certain macrolide antibiotics like clarithromycin and azithromycin (used in respiratory tract infections) does just that.

As a child, you probably thought a week took forever and parents certainly thought days crept by after having an infant.

"Time flies when you are having fun" and COVID-19 quarantines and lockdowns were not fun.

A new study also finds what psychologists warned about; the effects on those with depression issues could be even worse. Unlike a new job or moving to a new place, where time also 'seems' to slow down, the new paper found that distortions to the passage of time were also present later into the global pandemic.

On April 24th, 1990, the Hubble Space Telescope was launched, and though it had bumpy childhood once the problems were fixed it has well exceeded its mission expectancy. A good thing too. The James Webb Space Telescope that was supposed to replace it 13 years and billions of dollars ago still hasn't launched, and when it eventually does, if things don't work, no space shuttle can reach it.

The Red Sea is about 1000 miles long and at most just over 170 miles wide. The Greeks called it a sea but they also called the Persian Gulf a sea.

It may instead be an ocean, because an ocean basin exists between Africa and the Arabian Peninsula. The Greeks did not know that and the problem in knowing now is that the oceanic crust along the narrow, north-south aligned rift is widely buried under a thick blanket of salt and sediments, which complicates direct investigations.

In 1946, with World War II over, archaeologists got back to work and over 10 years found discarded Hebrew Bible manuscripts in 12 Ein Feshkha Caves near the Dead Sea in the West Bank. Fragments o these "Dead Sea Scrolls" include the Apocrypha, except for the Book of Esther, which may not have survived over time.

No one knows who printed most older works, for the Christian Bible it was anonymous monks, and the Dead Sea Scrolls also contain no attribution, but there has been speculation about who may have written them. Some sought to at least connect them by handwriting.

In 2019, Christiansburg, Virginia's 22,000 residents became the first place in the U.S. to have a residential drone delivery service.

Yellow-winged drones with small cardboard boxes owned by Wing, a company owned by Alphabet (basically, Google) are now one of numerous trial services operating today. But regulations for giant planes full of fuel are not ready for delivery of the future, and the only way to make government get ready is public interest. Without proactive guidelines, the public will be stuck with activists doing to drones what they did to agriculture and cell phones.
