An international team of researchers has uncovered what appears to be fragments of 75 million-year-old DNA from a dinosaur hatchling, bringing the concept behind Jurassic Park one step closer to reality. Previously, it was broadly accepted that the maximum amount of time that DNA could survive in a fossil was
All lifeforms across the entirety of the planet Earth have one thing in common, in that there is only one genetic code shared amongst all of the biological kingdoms, a singular chemical language handed down through the planet’s history, from the earliest single-celled creatures to the complex organisms that
Nobel Laureate, author, researcher and experiencer Kary B. Mullis has died at the age of 74. Mullis revolutionized the field of DNA research—and indeed all disciplines that involve the use of our genetic code—with his invention of the biochemical process known as the polymerase chain reaction. Mullis is also an
The clinical definition of physical death occurs when an individual’s heart stops beating and brain stops functioning, but what about other biological functions that still carry on after these two admittedly important processes cease? Medical science has long assumed that neurons degrade quickly after their supply of oxygen and nutrients are cut off, but a recent study on post-mortem cellular processes has upended these traditional notions of how long the body’s cellular processes continue after death, showing that some types of cells can be not only alive for days afterward, but some are also more active than when the individual was still alive and kicking.
