Interestingly, some forms of cancer can alter the smell of urine and ants may be able to detect those changes. Their findings on the potential use of ants as “bio-detectors” of cancer were published in the […]
I read an interesting review article explaining how cells evolved the ability to kill off pathogens and, in turn, how pathogens evade death. It is kind of like a perpetual game of ‘cat and mouse’ in which the interaction between animals and pathogens drives the evolution of host defenses against infections while at the same time driving the evolution of pathogen strategies to avoid detection. According to the review article, […]

Amazingly, that is the equivalent to how much sugar a hummingbird needs to support their rapid wingbeats during flight. In fact, hummingbird flight muscles are the fastest on record, allowing the birds to flap their wings at a rate of up to 200 beats per second! That explains why they are always at my […]
