Researchers Worldwide Rally to Help Scientist Exposed to Ebola
SciecneInsider has the details surrounding an Ebola researcher who pricked her finger with a needle during an experiment last week. Virologists around the world are collaborating to try to save their colleagues life. An exposure to Ebola from a needle stick does not often lead to infection with the deadly illness, but a group of scientists immediately got together to discuss a long list of experimental vaccines and treatments that could possibly prevent infection or slow progression of the disease. As a result, the exposed researcher was given a vaccine that has previously been shown to provide protection in monkeys who had been exposed to Ebola. The incubation period of Ebola is typically between 4 and 21 days, and it has only been 6 days since the needle stick incident. Thus far there is no indication that the researcher has contracted an Ebola infection, but virologists are anxiously following her case.
Researchers have many questions about the modernization of Pakistan’s nuclear-capable aircraft and associated air-launched cruise missiles.
The SIPRI chapter describes the nuclear weapon modernization programs underway in each nuclear-armed state and provides estimates for how many nuclear warheads each country possesses.
FAS researchers Hans Kristensen and Matt Korda with the Nuclear Information Project write in the new SIPRI Yearbook 2024, released today.
The total number of U.S. nuclear warheads are now estimated to include 1,770 deployed warheads, 1,938 reserved for operational forces. An additional 1,336 retired warheads are awaiting dismantlement, for a total inventory of 5,044 warheads.
