🔬 Science Fact #7988

Phage therapy — using viruses to kill bacteria — is making a comeback as antibiotic resistance grows.

🔬 Science Fact #7986

The influenza virus mutates so rapidly that a new vaccine is required every year.

🔬 Science Fact #7985

Viruses are not considered living organisms — they can only replicate inside a host cell.

🔬 Science Fact #7984

Some bacteria can survive in nuclear reactors — Deinococcus radiodurans can repair DNA damage from radiation.

🔬 Science Fact #7983

Archaea — single-celled organisms distinct from bacteria — were only recognized as a separate domain of life in 1977.

🔬 Science Fact #7982

Prions are misfolded proteins that cause other proteins to misfold — they cause diseases like BSE and CJD and cannot be destroyed by normal sterilization.

🔬 Science Fact #7981

Bacteria can share genes with each other horizontally — across species — through a process called horizontal gene transfer.

🔬 Science Fact #7979

Francis Crick dreamed the double helix structure of DNA — and rushed to the Eagle pub to announce 'we've discovered the secret of life.'

🔬 Science Fact #7977

Werner Heisenberg developed quantum mechanics while on a remote island recovering from hay fever.

🔬 Science Fact #7975

Louis Pasteur developed the germ theory of disease, invented pasteurization, and created vaccines for rabies and anthrax.

🔬 Science Fact #7974

Dmitri Mendeleev created the periodic table and correctly predicted the properties of yet-undiscovered elements.

🔬 Science Fact #7970

Alexander Fleming noticed that a mold contaminating his petri dish killed bacteria — and followed up on the observation.

🔬 Science Fact #7969

Lise Meitner co-discovered nuclear fission — but the Nobel Prize was awarded only to her male collaborator.

🔬 Science Fact #7968

James Clerk Maxwell unified electricity and magnetism into a single theory — and predicted the existence of radio waves.

🔬 Science Fact #7967

Carl Friedrich Gauss contributed to number theory, statistics, electromagnetism, and geodesy — among other fields.

🔬 Science Fact #7966

Emmy Noether developed Noether's theorem — linking symmetry and conservation laws — called the most important theorem in physics.

🔬 Science Fact #7962

Richard Feynman was a Nobel laureate physicist who also cracked safes for fun and played bongo drums.

🔬 Science Fact #7961

Gregor Mendel, the father of genetics, was a monk who experimented on pea plants in a monastery garden.

🔬 Science Fact #7960

Rosalind Franklin's X-ray crystallography images were critical to discovering DNA's double helix structure.

🔬 Science Fact #7959

Archimedes discovered the principle of buoyancy by noticing water displacement in his bath — and allegedly ran naked through the streets shouting 'Eureka!'

🔬 Science Fact #7957

Nikola Tesla had a photographic memory and could visualize complete inventions in his mind before building them.

🔬 Science Fact #7953

Isaac Newton developed his theory of gravity, laws of motion, and calculus largely during a 2-year quarantine from the plague.

🔬 Science Fact #7949

Cacao (raw chocolate) contains theobromine — a mild stimulant related to caffeine that also dilates blood vessels.

🔬 Science Fact #7947

Raw honey contains enzymes, antioxidants, and antimicrobial compounds destroyed by heating.

🔬 Science Fact #7941

Red wine contains resveratrol — a polyphenol with potential anti-aging effects in animal studies, but evidence in humans is limited.

🔬 Science Fact #7931

Green tea's EGCG (epigallocatechin gallate) has been studied extensively for cancer prevention and metabolic health.

🔬 Science Fact #7926
