🔬 Science Fact #4717

DNA can store data — researchers have encoded entire books, photos, and operating systems into DNA molecules.

🔬 Science Fact #4715

Chlorofluorocarbons (CFCs) used in refrigerants destroyed stratospheric ozone — the Montreal Protocol of 1987 phased them out globally.

🔬 Science Fact #4714

The speed of sound in steel is about 5,100 m/s — roughly 15 times faster than in air.

🔬 Science Fact #4713

🔬 Science Fact #4707

General relativity predicts that massive objects warp spacetime — confirmed by observing starlight bending around the Sun.

🔬 Science Fact #4706

Fire is a plasma — a hot, ionized gas — rather than a solid, liquid, or conventional gas.

🔬 Science Fact #4705

A single lightning bolt contains about one billion joules of energy but lasts only a fraction of a second.

🔬 Science Fact #4704

The photoelectric effect — used in solar panels — cannot be explained by classical physics and was one of the first quantum discoveries.

🔬 Science Fact #4703

Supercooled water can remain liquid well below 0°C if there are no nucleation sites for ice crystals to form.

🔬 Science Fact #4702

Nikola Tesla claimed to have received signals from Mars through his radio experiments, though scientists now attribute these to natural phenomena.

🔬 Science Fact #4667

The human brain can store roughly 2.5 petabytes of information — equivalent to 3 million hours of TV.

🔬 Science Fact #4650

🔬 Science Fact #4649

The average person has 100,000 hairs on their head, each growing about 15 cm per year.

🔬 Science Fact #4647

Mitochondria have their own DNA, separate from nuclear DNA, supporting the theory that they were once independent bacteria.

🔬 Science Fact #4644

The brain's default mode network is active during mind-wandering and is linked to self-referential thought.

🔬 Science Fact #4643

Blood type is determined by antigens on the surface of red blood cells — the ABO and Rh systems are most important.

🔬 Science Fact #4642

Adipose (fat) tissue is now recognized as an endocrine organ — it secretes hormones including leptin and adiponectin.

🔬 Science Fact #4641

Cortisol, the stress hormone, suppresses the immune system — chronic stress makes people more vulnerable to illness.
