Goodbye Rosetta!

Rosetta is scheduled to crash land on Comet 67P at 11:18 GMT today. Even if some of its systems remain operational, on-board software will ensure everything is shut down on contact.



Materials changing their shape

Unlike other shape-shifting materials which transform when triggered by light or heat, a team of scientists have come up with a polymer which can change at a pre-determined time. The chemistry behind the transformation can be read at


Curing all known disease

Facebook founder Mark Zuckerberg and wife Priscilla Chan have declared their aim to cure, prevent and  manage all disease by the end of the century.

Chan and Zuckerberg will stump up at least $3bn (£2.3bn) for the effort over the next 10 years. That is not a vast sum for the task ahead. The new Francis Crick Institute in London, now filling with 1,400 scientists, could be built and run for 10 years on that. The Wellcome Trust itself will spend £5bn on biomedical research in the next five years alone. But part of Chan and Zuckerberg’s hope is to grow a movement to fund science: where they have led, they want other wealthy individuals to follow.

Goodbye Rosetta!

13 years after its launch Rosetta,  the European Space Agency’s mission to land a probe on the comet 67P/Churyumov-Gerasimenko, is coming to an end. At the end of this month the space craft will be crashed into the comet and all communications will cease.


Use high factor sunscreen

With this hot weather, make sure you use high factor sunscreen. Recent research has shown that using high factor sunscreen, compared with low factor sunscreen, can decrease the risk of melanoma by 33%. However, you must remember to keep reapplying it and avoid the sun when it is at its highest in the sky.
