A study of genetically identical mice is providing some hints about humans. How can one identical twin be a wallflower while the other is the life of the party?
The study of 40 young mice found that their behavior grew increasingly different over three months, even though the mice shared the same genes and lived in the same five-level cage, researchers report Thursday in the journal Science.
In a case considered pivotal to the future of science and medicine, the justices of the U.S. Supreme Court seemed skeptical Monday about a claim that human genes can be patented.
Contending that genes can be patented are the biotech and pharmaceutical industries, which see patents as the keys to new scientific exploration. On the other side are doctors, patients and many scientists, who see gene patents as an attempt to monopolize and block future exploration in the new universe of genetics.
Same-sex marriage got huge headlines at the Supreme Court last month, but in the world of science and medicine, the case being argued on Monday is far more important. The lawsuit deals with a truly 21st century issue — whether human genes may be patented.
The man whose research led to the world's first test-tube baby more than three decades ago, has died at age 87.
Robert Edwards, who later won the Nobel Prize, began experimenting with in vitro fertilization, or IVF, in the late 1960s. His work, controversial at the time, eventually led to the birth of the world's first "test tube baby," Louise Brown, on July 25, 1978.
Since then, IVF has resulted in about 5 million babies worldwide, according to the European Society for Human Reproduction and Embryology.
