Ticks

How ticks became bioweapons

On December 18 last year, Donald Trump signed into law an order to “review and report on biological weapons experiments on and in relation to ticks [and] tick-borne diseases.” The investigation is long overdue but even so, the facts it uncovers will come as a shock to many. A growing body of evidence shows that during the Cold War ticks were tinkered with and used as delivery mechanisms for biological warfare agents. And these weaponized ticks may have been released both intentionally and unintentionally on an unsuspecting public by the US military. Ticks and the diseases they transmit (such as Lyme) pose a growing threat to Americans, the military and to agriculture. Record numbers of tick bites have been reported in New York (in 2024), Maine (in 2024), and Wisconsin (in 2023).

Map reveals where in Scotland Lyme-infected ticks are most likely to get you

From our UK edition

Researchers can now predict where in Scotland you are most likely to encounter ticks that carry Borrelia burgdorferi, the bacterium that causes Lyme disease. If that wasn’t enough to make you reconsider those picnic plans, then they have also forecast that this risk will increase as global temperatures rise. In a recent paper, the researchers predicted that people were more likely to come into contact with an infected tick in the months of August and September. They also identified both the Highlands and Tayside as areas of particular risk. Their map can be viewed in full here.
