Mother's Curse (wikipedia.org)
In biology, mother's curse is an evolutionary effect that males inherit deleterious mitochondrial genome (mtDNA) mutations from their mother, while those mutations are beneficial, neutral or less deleterious to females.

How the Non-Essential Spleen Could Regenerate Vital Organs Inside the Body (discovermagazine.com)
The idea of using the body’s own organs as mini bioreactors to grow replacement tissue or even regenerate other organs might sound like something out of a science fiction movie, but it's already becoming reality in cutting-edge labs around the world.

Near-infrared vision in humans enabled by upconversion contact lenses (sciencedirect.com)
Humans cannot perceive infrared light due to the physical thermodynamic properties of photon-detecting opsins. However, the capability to detect invisible multispectral infrared light with the naked eye is highly desirable.

Caesar's Last Breath (charliesabino.com)
How many molecules from Caesar’s last breath do we inhale with each breath we take? Shockingly, the answer is about one molecule—we actually do share breaths with Caesar! And, by extension, every breath we take is composed of the previous breaths of everyone who ever lived—Socrates, Lincoln, Einstein, etc. Isn’t that crazy?

Living beings emit a faint light that extinguishes upon death, study (phys.org)
The light of someone's life might not be just another person, but light in the literal sense. According to a recent study by researchers from University of Calgary, every living system emits light without requiring external excitation due to a biological phenomenon known as ultraweak photon emission (UPE).

Model Organisms Are Not Static (asimov.press)
About 70 percent of scientists say they have tried and failed to reproduce an experiment performed by their peers. And animal studies are, perhaps, among the least reproducible of all experiments because, in an effort to reduce the number of animals used in research, scientists often avoid repeating them to confirm positive results.1 When animal studies are replicated, however, they often yield different outcomes.

Saliva Is a Critical but Underestimated Bodily Fluid (medscape.com)
Human life would be difficult to sustain without saliva. Its fundamental role in keeping the oral mucosa hydrated is essential for core functions such as swallowing, tasting, and speaking. However, recent research has revealed that saliva does far more than previously understood. Specific components may eventually serve as noninvasive biomarkers for a variety of diseases.
