President Joe Biden and Russian President Vladimir Putin concluded their summit on Wednesday with an agreement to return their nations ambassadors to their posts in Washington and Moscow and a plan to begin work toward replacing the last remaining treaty between the two countries limiting nuclear weapons.
For months, U.S. Strategic Command chief Adm. Charles Richard has been sounding the alarm about the growing nuclear threat from China.
Now we know why.
In the past month, civilian analysts studying satellite images have found two large fields of apparent nuclear missile silos â at least 230 of them â under construction in remote north-central China.

The University of Nebraska has launched a 5-year project to help safeguard the U.S. food supply. The project will address agricultural and natural resources security, defense, and countermeasures; biological defense in support of the U.S. Department of Defense, Department of Homeland Security and other government stakeholders; development and deployment of biosurveillance, biodetection and diagnostic tools; and pandemic preparedness related to human, livestock and crop plant diseases that could result in disruptions to the U.S. and global food systems.
The University of Nebraska–Lincoln’s Institute of Agriculture and Natural Resources and the National Strategic Research Institute at the University of Nebraska will begin a five-year partnership to help safeguard the U.S. food supply.

The Biden Administration recently agreed to an unconditional
five-year extension of the New Strategic Arms Reduction Treaty (New START) with the Russian Federation before it was scheduled to expire on February 5, 2021. New START restricts the number of strategic nuclear delivery systems and warheads each country can deploy, but the treaty contains significant flaws. Instead of continuing the Trump Administration’s efforts to seek improvements to the treaty, the United States received nothing in return for its agreement to extend. In fact, just days later, perhaps feeling empowered to dictate terms, Russian Deputy Foreign Minister Sergei Ryabkov stated that any future treaty must include U.S. missile defense.REF
The experiments revealed that in open air, simulants decayed 10 to 1,000 times faster than in laboratory settings. These data indicate that laboratory tests underestimate the rate of agent decay that occurs outdoors, and on their own, laboratory tests are not sufficient in understanding the decay process outdoors.
To learn how biological threat agents decay upon interacting with variables in the open air, the Defense Threat Reduction Agency’s Chemical and Biological Technologies Department (DTRA CB) developed a new, state-of-the-art test apparatus, the Captive Aerosol Growth and Evolution System (CAGES).
“Due to various challenges posed by outdoor testing, it was generally assumed by scientists that biological threat agents aged and decayed at similar rates indoors as they did outdoors. Our goal was to test this theory,” said Richard Mathieson, Science & Technology Manager, DTRA CB.
