Sound Waves: The Symphony of Physics: Making sounds In this programme, Dr Helen Czerski investigates the extraordinary science behind t...he sounds we're familiar with and the sounds that we normally can't hear.
She begins by exploring the simplest of ideas: what is a sound? At the Palace of Westminster, Helen teams up with scientists from the University of Leicester to carry out state-of-the-art measurements using lasers to reveal how the most famous bell in the world - "Big Ben" - vibrates to create pressure waves in the air at particular frequen
Inside science : Moon dust ; Elecro-ceuticals ; Soil and climate change ; Dogs' tails A NASA spacecraft the size of a sofa is currently orbiting the Moon, gathering info...rmation about the toxic perils of moon dust. Dirt from the moon is sharp, spiky and sticky and it caused enormous problems for early astronauts as Professor Sara Russell from the Natural History Museum tells Dr Lucie Green. Joining Lucie from NASA HQ in Washington DC, Sarah Noble, programme scientist on the LADEE Mission, tells her that understanding the make-up and movement of lunar dust is vital to ensure humans
Inside science : European ancestry; Cern at 60; Graphene plasters; Penguins European AncestryNew genetic investigation of ancient human remains, combined with ...archaeological evidence, is shedding new light on the origins of the early European populations. The international team has provided a detailed analysis of waves of immigration from the near east into Europe, and the emerging agricultural practices that came with it, which has come to dominate the traditional practices of indigenous residents.CERN - Artificial retinaThe human eye and the parts of the brain that pr
Circle of Life On our journey from cradle to grave, we mark the most important moments of our live...s with rituals and ceremonies around birth, marriage and death. These life events, and often the emotions around them, are universal. Yet across the globe we perform them in extremely different ways.
With the birth of a child, parents will do anything to protect them. In Japan a 400 year-old ceremony called Naki Sumo sees mothers hand over their babies to professional sumo wrestlers, who then compete to make them
