This week on the Naked Scientist - a way to predict heart attacks that are about to happen, a way to block baldness, and we know there's an absolute zero for temperature, but is there an absolute maximum that you can't exceed?

Dr Karl and Dr Rhod try to answer your science questions. This week we ponder why animal eyeballs don't freeze in the Arctic and the relief of the Einsteinian Relativists.

Dr Karl joins Dr Rhod to answer your science questions. Counting calories, making rain and LEDs making more light than they should are just some of the mysteries delved into.

On the latest editon of the Naked Scientist - Antimatter, the rules of physics say there should be at least as much antimatter in the Universe as there is matter, the material that we are made from. But scientists can't find it, suggesting either that we've got something wrong, or something else very exciting and important must be happening. Also, why the hand you type with can affect how you feel. As well as a look at some of this week's other leading science breakthroughs

Dr Karl and Dr Rhod join forces to examine solar flares as one heads towards the earth. Microwaves and electromagnetic pulses are also under the spotlight.

Why the working classes are more gentlemanly than the upper classes, how hippos can select the sex of their offspring, and the discovery of a device which stops people talking.

Is the moon moving away from us and what could that mean...how much salt is too much...and why are water molecules like boomerangs?

Dr Chris Smith and colleagues talk us through the week's science news including the recreation of 30 thousand year old flowers and the importance of what mothers eat before conception.

Why juicing greens might not be the best idea, exactly what sound is and why planets are spherical are all under the microscope as Dr Giles joins Dr Karl.

Dr Chris Smith and colleagues explore one of the biggest computers that's getting bigger and one of the smallest computers that'll be with us soon. Also, what do some fruit flies use alcohol for?
