The tree which moves some to tears of joy is in the eyes of others only a green thing that stands in the way. Some see nature all ridicule and deformity… and some scarce see nature at all. But to the eyes of the man of imagination, nature is imagination itself.

Excess hair, especially on women, has a long history of sideshow exploitation (and legitimate employment) and has several possible causes.
Meaning “extra hair growth from birth”, congenital hypertrichosis is a very rare condition, but is also X-linked dominant, in several cases. When an affected female has a child, there’s a 50/50 chance they’ll be affected, and when an affected male has a child, they’ll be affected by the mutation 100% of the time. Interestingly, there are several mutations known to cause congenital hypertrichosis, but they’re all X-linked.
These forms of hypertrichosis appear after birth, and are most often caused by a reaction to medication, eating disorders, and internal malignancies (cancer). The most common form of acquired hypertrichosis is the coating of lanugo (soft insulating hair most often found on preterm infants) in anorexia nervosa patients. This extra hair will fall off naturally once the body begins to receive regular proper nutrition again.
This is not a form of hypertrichosis, but some “bearded ladies” have had the condition known as “hirsutism”. Hirsutism is not a disease in and of itself, but is a symptom, where increased androgen sensitivity in women causes terminal hair growth in areas where vellus hairs normally grow - most notably the face and chest.
Polycystic ovarian syndrome is the most common cause of hirsutism, and is what the sideshow lady Annie Jones had. Obesity, Cushing’s disease, acromegaly, ovarian tumors, and type 2 diabetes can also cause excess androgenic hair. Of course, treating the underlying condition is the optimal way to reduce hirsutism, but many conditions that cause it can only be treated.
There are several medications that can be taken to reduce the levels of this hair growth, but as they’re all hormone-based and somewhat riddled with side-effects, most women who have hirsutism will opt for hair removal, instead. Or they’ll embrace it, like Harnaam Kaur!

A Staph infection can’t start unless Staphylococcus cells first cling to a surface, which is why scientists are exploring bacteria-resistant materials as a line of defense. Berkeley Lab scientists investigated how individual S. aureus cells attach to metallic nanostructures of various shapes and sizes that are not much bigger than the cells themselves.
"By understanding the preferences of bacteria during adhesion, medical implant devices can be fabricated to contain surface features immune to bacteria adhesion, without the requirement of any chemical modifications," says Mohammad Mofrad, a faculty scientist in Berkeley Lab’s Physical Biosciences Division and a professor of Bioengineering and Mechanical Engineering at UC Berkeley.

Scientists have revived a giant virus that was buried in Siberian ice for 30,000 years — and it is still infectious. Its targets are amoebae, but the researchers suggest that as Earth’s ice melts, this could trigger the return of other ancient viruses, with potential risks for human health.
The newly thawed virus is the biggest one ever found. At 1.5 micrometres long, it is comparable in size to a small bacterium. Evolutionary biologists Jean-Michel Claverie and Chantal Abergel, the husband-and-wife team at Aix-Marseille University in France who led the work, named it Pithovirus sibericum, inspired by the Greek word ‘pithos’ for the large container used by the ancient Greeks to store wine and food. “We’re French, so we had to put wine in the story,” says Claverie. The results are published in Proceedings of the National Academy of Sciences1
Could marvel at these all day long!
