* 1972 – Seventy-four nations sign the Biological Weapons Convention, the first multilateral disarmament treaty banning the production of biological weapons.

Biological weapons ( often termed " bio-weapons " or " bio-agents ") are living organisms or replicating entities ( viruses ) that reproduce or replicate within their host victims.

Biological weapons may be employed in various ways to gain a strategic or tactical advantage over an adversary, either by threats or by actual deployments.

Offensive biological warfare, including mass production, stockpiling and use of biological weapons, was outlawed by the 1972 Biological Weapons Convention ( BWC ).

Biological weapons also target fisheries as well as water-based vegetation.

Biological specimens typically require to be chemically fixed, dehydrated and embedded in a polymer resin to stabilize them sufficiently to allow ultrathin sectioning.

Biological tissue must be supported in a hard matrix to allow sufficiently thin sections to be cut, typically 5 μm ( micrometres ; 1000 micrometres

Biological circuit gates based on DNA materials have been engineered as molecular machines to allow in-vitro drug delivery for targeted health problems.

Biological organic materials seem to allow your body to " breathe.

Biological simulations may allow the player to experiment with genetics, survival or ecosystems, often in the form of an educational package.

Biological warfare is the intentional use of living microorganisms or their toxic products for the purpose of destroying or reducing the military effectiveness of man.

Biological agents are, moreover, suitable for delivery through enemy sabotage which imposes many problems in defense.

Suggestions for improvement in the operation of CITES include: more regular missions by the Secretariat ( not reserved just for high profile species ); improvement of national legislation and enforcement ; better reporting by Parties ( and the consolidation of information from all sources-NGOs, TRAFFIC, the wildlife trade monitoring network and Parties ); more emphasis on enforcement-including a technical committee enforcement officer ; the development of CITES Action Plans ( akin to Biodiversity Action Plans related to the Convention on Biological Diversity ) including: designation of Scientific / Management Authorities and national enforcement strategies ; incentives for reporting and timelines for both Action Plans and reporting.

Biological vectors are often responsible for serious blood-borne diseases, such as malaria, viral encephalitis, Chagas disease, Lyme disease and African sleeping sickness.

Legal action by the Center for Biological Diversity led to federal listing of the cat on the endangered species list in 1997.

Critics, including the Center of Biological Diversity and New Mexico Department of Game and Fish, were concerned the jaguar was being sacrificed for the government's new border fence, which is to be built along many of the cat's typical crossings between the United States and Mexico.
