Adaptive octopus

Cephalopods (like octopus and squid) can make edits to a large portion of their RNA (which is used to make proteins), allowing their cells to react to situations without changing their DNA. By using this mechanism, they can try out proteins with different functions without needing to wait for evolution to take place. However, the…

Blood brothers

Recently, scientists have found out that bone marrow are not the soloist involved in making blood – lungs are also involved! Not only are lungs responsible for making approximately 50% of the platelet (things that help blood clot), cells in the lungs can move to and repopulate the bone marrow in mice with stem cell…

Ants on stilts

In addition to using the position of the sun as compass to find their way home, ants also use an inbuilt pedometer that tracks how many steps they have taken. To show that this step-tracking mechanism is important to ants’ sense of direction, researchers changed the sizes of the steps by either tying them to…

Viking cats

The origin and spread of these adorably nasty little creatures are still not well understood. A recent study has sequenced DNA from more than 200 cats that lived between 200 to 15,000 years ago, from more than 30 archaeological sites across Europe, the Middle East and Africa. The researchers found that the cat population appear…
