Bioluminescent algae works similar to cracked glow sticks. When agitated (or cracked), ruptures in the membranes cause a chemical reaction that emits light!
There are many purposes for beetle iridescence including camouflage, attracting mates, thermo-regulation, and can even serve as warning signals to predators.
Octopuses have the largest brain-to-body ratio among invertebrates. Many have been observed using tools, such as shells or discarded objects, for protection/shelter.
This behavior showcases their high cognitive abilities.
Hair cells play a crucial role in the hearing process. Inner hair cells (IHCs) are connected to nerves that stimulate the auditory portion of our brains. Outer hair cells (OHCs) work similarly in the cochlea. IHCs help with sound quality and clarity while OHCs help with pitch.
A new study uncovers the self-repair ability of auditory hair cells. This newfound resilience could reshape how we approach prevention and treatment of hearing loss.

Happy birthday to the incredible Nikola Tesla!
He is credited with discovering remote control, fluorescent lighting, and the type of energy we use to power our homes.
Gorgeous artist representation of mitosis! The video has been simplified from 23 sets of chromosomes to 6 so it will be easier for the viewer to visualize the division process.
Mitosis is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Such a division gives rise to genetically identical cells in which the total number of chromosomes is maintained

Korbut got a 9.8 on this move, so why was it banned?
After this maneuver, the federal international code of gymnastics deemed that standing on the high bar was too dangerous.
It was discovered that ancient Roman architecture's longevity was due to the use of limestone. When wettened by rain, minerals from limestone deposit in micro-cracks and act as a binding cement to repair itself.
Maybe this new information will contribute to modern buildings!

Pluto looks nothing like what we saw in our textbooks growing up!
Pluto's surface sports a remarkable range of subtle colors, enhanced in this view to a rainbow of pale blues, yellows, oranges, and deep reds.
Pandas have a reputation for being lazy due to their bamboo diets!
This is because bamboo is low in nutrients,, so pandas conserve energy by limiting their physical activity. Pandas also have a slow metabolic rate, which contributes to their seemingly lazy lifestyle.
Abdominal thrusts, also known as the Heimlich maneuver, is a first aid procedure used to treat upper airway obstructions (or choking) by foreign objects. It was devised by medical researcher Henry Heimlich, who used it for the first time when he was 96

This may be a difficult concept to wrap your mind around. Jupiter actually orbits a center (called a barycenter) of our solar system slightly off kilter from the sun. This is due to Jupiter's enormous size enforcing its own gravity on the sun, pulling it away from the baycenter.
In 1954, President Arbenz sought to redistribute unused lands held by foreign companies. As a result, Chiquita (formerly known as United fruit company) staged a coup with other corporations in Guatemala. The coup was supported by the United States due to fears of communism.
