Are aliens hiding in plain sight?

Several missions this year are seeking out life on the red planet. But would we recognise extraterrestrials if we found them?In July, three unmanned missions blasted off to Mars – from China (Tianwen-1), the US (Nasa’s Mars 2020 Perseverance Rover) and the United Arab Emirates (Hope). The Chinese and American missions have lander craft that will seek signs of current or past life on Mars. Nasa is also planning to send its Europa Clipper probe to survey Jupiter’s moon Europa, and the robotic land...

Scientists launch proposal to create synthetic human genome

Twenty years after scientists learned to ‘read’ the human genome, scientists are hoping to write their own synthetic version of the DNA recipe for lifeTwo decades ago we learned to “read” the human genome – the entire three-billion-letter DNA recipe for life coiled in the human chromosomes. Now scientists want to start writing it. A $100 million global consortium has been proposed, to devise ways to assemble human DNA in the laboratory so as to better understand how it works, and look for new wa...

JR Batchelor obituary

Immunologist who played a significant role in the development of tissue and organ transplantsThe most dramatic medical advance in the second half of the 20th century was, arguably, in the field of tissue and organ transplantation – now commonplace for a great many organs, but unthinkable in the 1950s. Richard Batchelor, who has died aged 84, played a very significant part in this revolutionary development.As director of the Blond McIndoe Research Centre in East Grinstead, West Sussex, founded as...

The epigenetics of The X-Files

Epigenetics is helping us to solve DNA mysteries that cannot be explained by genetics alone. It might even help explain some of the spooky phenomena described in the 1990s science documentary series The X-Files …The X-Files was my absolute favourite television show in the 1990s. My flatmates and I would tune in every week to watch intrepid FBI agents Fox Mulder and Dana Scully track down assorted aliens, psychics, vampires, ghosts, and government conspiracies. We bought the soundtrack CD; we eve...
