A Giant Interstellar Cloud May Have Caused Quaternary Ice Age

A Giant Interstellar Cloud May Have Once
Enveloped Earth, Potentially Causing Ice Ages.
Astronomers suggest this cold, dense cloud
compressed our sun’s protective field between
two and three million years ago, leaving the
Earth exposed to cosmic material

Customs and Border Protection Crackdowns on some De Minimis Shipments into the US 02JUN2024

Customs and Border Protection Crackdowns on some De Minimis Shipments into the US

Currently, US Customs and Border Protection is cracking
down on de minimis Shipments from China into the US.
It is now currently limited to air shipments from China.
However, this crackdown could extend eventually to other
countries and ultimately to some degree to marine shipments.
  Because de minimis shipping consists of any goods that
is less than 800 dollars, this crackdown, might eventually
greatly delay the shipping of any package of goods and
lengthen the time it would to ship anything into the
United States. Also, any package of de minimis goods
shipped into the United States will be more closely scrutinized
by the CPB in terms of whether it is properly declared in
description and price by the sender.

  Although it is nothing to worry about now, the situation
could change in the future.


Below are some new articles-

"Entry Type 86 allows the import of goods into the
US without the payment of duties and taxes, if the
value of the shipment is less than $800, the de minimis
threshold."
