Do dogs see in black and white?
This was the belief for a long time but now we know better! They CAN see colours - just not in the same way we do.

Our bodies naturally have enzymes and proteins that prevent blood from clotting, allowing it to stay in liquid form. However, as soon as we are wounded, healthy adult bodies start the process of blood clot formation. But did you know that leeches have a special anticoagulant they secrete to prevent this so they can continue to feed?

Hi all

I'm sorry to announce that, due to unforeseen circumstances, the Biospeak session on 'Unravelling DNA' scheduled for Saturday the 26th will be postponed.
However, a new date will be announced soon so keep an eye out!

Mutations are changes in DNA base sequences. Insertions and deletions (Indels) of bases are the most common types of mutations we come across.

DNA repair mechanisms are quick to identify when mutations occur and rectify them.
How quickly can you identify all the mutations?

How much do you know about DNA?
Despite it being the genetic material of many organisms, we're still learning things about this VERY COOL biomolecule!

Super excited about this next discussion!

'Unravelling DNA' will introduce some basic concepts about DNA, its importance in our body as well as to science in general, what happens when DNA mutates, and some lesser known but STILL VERY COOL things about this fascinating molecule!

Do join in on Saturday the 26th August 2023, 3.30 PM IST (Sri Lanka) and 11 AM GMT (UK).
