Cancer to be ‘birthed’ in lab to learn prevention instead of cure

Cancer to be ‘birthed’ in lab to learn prevention instead of cure

Technology
Cancer will be grown in a lab by scientists trying to find ways to stop the disease before it develops.A new transatlantic research alliance of scientists from the UK and US, working on a five-year, £55m budget, will "birth" a tumour in lab-grown human tissue. The International Alliance for Cancer Early Detection (ACED), made up of experts from Cancer Research UK and five top universities, hopes to promote "rapid, cost-effective" early intervention over the "expensive firefighting of late-stage disease". Scientists are already investigating how to take cells out of someone at high risk of developing cancer and reproduce them using a 3D printer to test under what conditions they are most likely to turn cancerous.They also hope to develop screening tests that will detect multiple cancers...

Star that birthed Tycho's supernova wasn't hot and bright

Science
Sept. 26 (UPI) -- An international team of scientists from the United States, Australia and Germany have offered new insights into the origins of Tycho's supernova.Until now, many astronomers assumed Tycho's supernova was formed by the explosion of a white dwarf that had been slowly stealing material from its companion star. But the latest analysis, published this week in the journal Nature Astronomy, suggests otherwise.First observed 445 years ago by the astronomer Tycho Brahe, Tycho's supernova is the most famous example of a Type Ia supernovae, the violent nuclear disruption of a white dwarf.In addition to serving as standard candles for cosmologists, Type Ia supernovae also play an important role in the formation and evolution of galaxies. The exploded shell of gas and dust serves as s...
