Ants can detect the scent of cancer in urine, scientists have found. Several types of cancer have been found to alter urine smell but experts have, for the first time, found ants to have this ...
The venom plays a central role in the biology of Red imported fire ants, such as in capturing prey, [1] and in defending itself from competitors, [2] assailants, [3] and diseases. [4] Some 14 million people are stung annually in the United States, [ 5 ] suffering reactions that vary from mild discomfort, to pustule formation, swelling, [ 6 ...
In the case of fire ants, the venom consists mainly of alkaloid (>95%) and protein (<1%) components. [2] Stinging ants cause a cutaneous condition that is different from that caused by biting venomous ants. Particularly painful are stings from fire ants, although the bullet ant's sting is considered by some to be the most painful insect sting.
Cancer is caused by genetic changes leading to uncontrolled cell growth and tumor formation. The basic cause of sporadic (non-familial) cancers is DNA damage and genomic instability. [1] [2] A minority of cancers are due to inherited genetic mutations. [3] Most cancers are related to environmental, lifestyle, or behavioral exposures. [4]
Most ants are capable of biting, stinging, and spraying irritant chemicals. [1] However, only relatively few species can harm humans; among which some can cause significant injury or, in rare cases, death. Like wasps, individual ants are capable of stinging multiple times as they do not lose their stingers. [2]
A transmissible cancer is a cancer cell or cluster of cancer cells that can be transferred between individuals without the involvement of an infectious agent, such as an oncovirus. [ 1 ] [ 2 ] The evolution of transmissible cancer has occurred naturally in other animal species, but human cancer transmission is rare. [ 2 ]
The latest curiosity is a video that surfaced on YouTube showing a phone placed on the ground where a group of ants is moving randomly. When the phone receives an incoming call, the ants start ...
[40] [9] Due to the prevalence of infection by H. pylori in middle-aged adults (74% in developing countries and 58% in developed countries in 2002 [41]), and 1% to 3% likelihood of infected individuals developing gastric cancer, [42] H. pylori-induced gastric cancer is the third highest cause of worldwide cancer mortality as of 2018.
