They secretly resume one of the longest experiments in history

 Researchers unearthed seeds that were hidden 142 years ago under a university campus   The experiment tries to find out how long the seeds can remain inactive in the soil without losing their ability to germinate The New York Times Dr.   Marjorie Weber   and her colleagues   at Michigan State University   are the ultimate custodians of   "Beal's seed viability,"   a centuries-old experiment that attempts to determine how long seeds can remain dormant in the soil without losing their ability to germinate.   Every 20 years, the caretakers of the experiment move to a   secret location on this university campus   and dig up a bottle, then spread its seeds on a dirt tray and see which ones grow. It is   one of the longest-running experiments in the world   , carried out from generation to generation for the last 142 years, according to a report published by   The New York Times   .   Scientists expect it to last at least another 80 years, until after the year 2100.

Artificially Introduced Genetic Errors That Can Change the Human Species

 A study by the Francis Crick Institute in London revealed that gene editing experiments carried out so far generated accidental mutations in 16% of cases   Errors introduced by gene editing could be passed from generation to generation He Jiankui looked nervous.   The Chinese researcher   at the Southern University of Science and Technology in Shenzhen has   been working on a top-secret project   for the past two years, and   was about to take   the podium at the International Summit on Human Genome Editing to announce the results. The audience watched anxiously.   People started filming on their phones.   The biologist had created the first genetically modified babies in the history of mankind.   After 3.7 billion years of continuous evolution undisturbed by natural selection, a life form had taken its innate biology into its own hands.   The result was twin girls who were born with altered copies   of a gene known as CCR5, which the scientist hoped would make them immune to HIV.   B
