Scientists Just Observed Epigenetic Memories Being Passed Down for 14 Generations

Scientists have made some incredible new discoveries on how our minds can literally affect our biology, especially through the study of epigenetics, the branch of science that looks at how inherited changes of phenotype (appearance) or gene expression are caused by mechanisms other than changes in the underlying DNA sequence. Instead of looking at DNA as the only factor controlling our biology, scientists are also looking at what’s actually controlling the DNA, which includes our thoughts. We receive genetic instructions from our DNA, passed down through generations, but the environment we live in can also make genetic changes. One of the more recent studies that explored this concept was conducted by a team led by scientists from the European Molecular Biology Organization (EMBO) in Spain. Scientists Prove How Far Environmental Genetic Changes Can Be Passed Down Through Generations To figure out how long the environment can leave a mark […] Read More

2011: High-speed 'space wedge' on track

23 June 2011 Last updated at 09:02 ET By Jonathan Amos Science correspondent, BBC News, Paris The IXV would be launched atop a Vega rocket The European Space Agency (Esa) is pressing ahead with its re-entry demonstrator known as the IXV, which it expects to launch in 2013. This distinctive wedge-shaped vehicle will be put at an altitude above 400km from where it will begin its flight back to Earth. Its suite of sensors should give engineers new insights into how objects fall back through the atmosphere. Ultimately, the data should inform better spacecraft design. Even probes sent to land on other worlds like Mars should benefit from the knowledge. “IXV is providing Europe with important technologies and a step to more ambitious programmes in the future,” said Antonio Fabrizi, one of Esa’s senior directors. He signed an agreement at the Paris Air Show that will lead to manufacture […] Read More
