Answer. We put this question to Ian Mercer: This is an interesting stone. This forms at very high pressure. This isn't a volcanic stone, this is a gemstone that forms as a mineral in rocks that are squeezed in between something. This is a stone which is intensely dichroic. It changes colour completely as you turn it round.
Predictions of the end of oil have a long and undistinguished history. In 1874 the state geologist of Pennsylvania said that all the oil would be gone by 1878. Needless to say, it wasn't. In the 1970s pundits predicted we would run out by they year 2000 and they were wrong too. The reason why current predictions of peak oil production are ...
Miriam - Yeah. Well, the studies like, like this one, help understanding the limits of song variation in fin whales, for example. This frequency decrease cannot go on forever and the study in Nature now confirms it because the structures that produce sounds in these species limits the range of frequency. These animals can produce sounds.
I found that, while walking, bees were making these vector paths, these straight line paths to find home and food. Now for this study, I found with a control experiment that surprisingly it seemed that bees were able to remember the straight line paths that they had constructed during previous days of foraging and would use those paths to ...
Kat - Yeah, absolutely. They are a protected species. A lot of effort goes into trying to survey and confirm the presence of water vole. Sally - Just looking around, we're not even in a particularly quiet part of the river, there's boats going past, we've had lots of dog walkers.
That matter is the source of say hydrogen in a nuclear reaction which is powering the sun and that energy is then ending up in me, as I explain, to make me push my ball down the stairs. So it's quite right, the energy is being converted is not being made or not being destroyed. Eusebius - Fantastic.
The appendix is essentially a little blind pouch. It's what anatomists call a diverticulum, and it projects off part of the large intestine, the colon, called the caecum. And in humans it's referred to as vermiform in shape, which just means worm-like. So it's a little cylindrical tube about a centimetre in diameter, and it's found in the lower ...

The evidence speaks for itself in the form of a long forgotten plant with Biblical roots. Chris Smith first met Sarah twenty years ago when she had been working on growing ancient date stones - dating back thousands of years - collected from Middle Eastern archaeological digs. Well now, with another ancient seed she found in a university ...
SKIN.jpg. A new study has found that surgical stitches that can pick up an electrical charge can help speed up the healing of skin wounds. Electrical potentials delivered to the skin by the conductive sutures made new skin cells grow to heal injuries far faster. The findings, published in Nature Communications, are the work of a team of ...
