- 1992 - The belief that adult mammal’s brain cells can not reproduce is dispelled. Science discovers that a protein could prompt mature nerve cells in mice to divide.
-
- 1993 - Massive Compact Halo Objects were discovered at the outskirts of the Milky Way. Called MACHOs that were thought to be the missing matter in the Universe. ( Today WIMPs are the more likely candidates for Dark Matter, Weakly Interactive Massive Particles.)
-
- Science cloned the first human embryos. This opens a book of ethical concerns.

-
- 1996 - Carbon isotopes dating of Greenland rocks put the history of life on Earth starting 3,850,000,000 years ago.
-
- Dolly the sheep is first mammal cloned from DNA.
-
- 1997 - Kyoto Protocol treaty for addressing Global Warming.
-
- Human embryonic stem cells have the potential to become nerves, blood, or any other tissue.
-
- Quantum behavior harnessed to transfer one photon’s polarization rate to a remote proton. Verifying “ action at a distance”.
-
- 1998 - Astronomers have data indicating the expansion of the Universe is picking up speed.
-
- 1999 - Genetic studies confirm that AIDS virus originated in chimps living in central Africa.
-
- A drug specifically targets chronic myelogenous leukemia cells, named Gleevec.

- 2001 - Genetic blue prints expected o find 100,000 genes but found only 33,000.
-
- Physics gets light pulses to stand still without destroying the photons.
-
- 2002 - A fossil skull of human ancestral species is dated at 6,000,000 years.

-
- 2003 - The SARS deadly viral pneumonia emerged in China ( Severe Acute Respiratory Syndrome).
-
- 2004 - A small human species lived on an Indonesian island as late as 18,000 years ago, called hobbits on the island Flores.
-
- 2005 - physics creates a Quark - Gluon plasma that is a liquid , not a gas as was expected as the primordial matter of the young Universe.
-
- 2006 - Astronomers demote Pluto to a Dwarf Planet.
-
- Astronomers report direct evidence for the existence of Dark matter in space.
-
- 2007 - Biologists turn human skin cells into stem cells, with out embryos.
-
- 2008 - A Mars lander confirms the presence of water on Mars.
-
