Summary

We're analysing the matter of antimatter this week to find out what is antimatter, how is it made and why's it so rare in the Universe? We talk to researchers at CERN who are capturing anti-hydrogen so scientists can study it properly for the first time, and Dave and Meera call in to the hospital to hear how antimatter holds the key to better body scans. Diana discovers how gravity bends a beam of light and there's also news of a novel way to neutralise HIV, researchers uncover how brains gauge the passage of time, and agriculture on the microscale: scientists have found the world's smallest...

0:00.0	Stripping down science January the 23rd. Welcome to the Naked Scientists with me
0:21.1	Chris Smith and with me Diana O' Carroll and this
0:24.0	week we're finding out what is anti-matter and how does it differ from normal
0:29.0	matter and we'll be also talking to someone who's managed to make anti-hydrogen, as well as finding out
0:34.8	how anti-matter holds the key to better body scans.
0:38.1	I'll also be investigating how gravity bends a beam of light.
0:41.6	Plus, the answer to why the journey home from somewhere
0:45.3	seems to go quicker than the outward leg.
0:47.1	You must have noticed that.
0:48.3	Well, researchers have shed some new light
0:50.1	on how the brain registers time.
0:52.4	And also, how a mouse with a human immune system is helping scientists to develop a new treatment
0:57.9	for HIV. If you'd like to get in touch to ask a question, you can tweet at naked scientists right on our
1:04.4	Facebook page to get there you go to naked scientist dot com forward slash Facebook or
1:08.3	drop us an email it's Chris at the naked scientist dot com.
1:13.4	The naked scientist podk. at The Naked Scientist.com The Naked Scientists Podcast is powered by UK Fast, the UK's best hosting provider on the web
1:20.3	at UKfast.co. UK. UKfast.co. K. and first up as we always do let's kick off with a look at some of this
1:34.2	week's top science new stories Diana what have you got for us this week?
1:37.4	Well a new study this week has found that in order to keep track of time our minds
1:42.0	exploit as many clues in the environment as they can get
1:44.6	hold of.
1:45.6	And this means that our internal clock isn't solely controlled by pre-programmed cells in the brain.
