And I say: 'Oh yeah, yeah, maybe, whatever.'"But in the intervening years, he more-or-l

How cells sense oxygen wins Nobel prize

Health
Three scientists who discovered how cells sense and adapt to oxygen levels have won the 2019 Nobel Prize for physiology or medicine.Our body's cells use oxygen to convert food into usable energy.The trio - British Sir Peter Ratcliffe and two Americans, William Kaelin and Gregg Semenza - discovered how cells adapt when oxygen levels drop.The Swedish Academy said their "elegant" findings were leading to treatments for anaemia and even cancer. It said: "The fundamental importance of oxygen has been understood for centuries, but how cells adapt to changes in levels of oxygen has long been unknown."Sir Peter Ratcliffe is based at the Francis Crick Institute in the UK, William Kaelin at Harvard in the US and Gregg Semenza at Johns Hopkins University in the US.O...

Nobel Prize-winning physicist Schrieffer dies in Florida

Technology
John Robert Schrieffer, a physicist who shared in the 1972 Nobel Prize in physics for developing a pioneering theory of superconductivity, has died. He was 88. Family members say Schrieffer died in his sleep at a nursing facility Saturday in Tallahassee, Florida, where he had been a professor at Florida State University at one time. Along with colleagues John Bardeen and Leon Cooper, Schrieffer was awarded the Nobel Prize in physics for developing the BCS theory. It is considered the first successful microscopic theory of superconductivity — the ability of certain materials to conduct electricity with practically zero resistance. In 2005, he was sentenced to two years in prison for killing a man and injuring seven other people while driving more than 100 mph (161 kph). He is survived by t
