Eight-year-old boy's discovery solves mystery of turtle shell

No other living vertebrate has gone to as much trouble to alter its body in such a way as to afford itself an impenetrable structure for protection as the turtle. But now, thanks to an eight-year-old boy, we may have to rethink why the turtle has a shell.

Space X looking for two more landing sites on Space Coast

Even though Space X successfully launched its Dragon spacecraft and brought back its Falcon 9 first-stage booster rocket to a safe landing on Monday, Space X now wants two more landing sites so it can do three rocket landings simultaneously.

It’s all in the genes: Why some chickens are bird flu resistant

Combating the risks associated with bird flu is of global importance. While some research focuses on treatment, and other parts on addressing transmission, another strand looks at patterns of susceptibility.

Altering gut microbes to reduce effects of fatty food

We avoid overeating by our guts sending messages to our brain. However, high fat foods can disrupt this neural network, according to new research. This means high fat food is doubly bad because we may want to eat more of it.

Ducklings are capable of abstract thought

Ducklings, it seems, are capable of abstract thinking. In fascinating new tests, ducklings, after being shown toy blocks, move towards new blocks that are of a similar color or shape to the ones the ducklings were shown previously.

Essential Science: Fashioning green electrodes thanks to biology

How can biological science help the electronics sector? The answer is bacteria helping to produce a new generation of nanoelectronic materials.

Space X launch and booster recovery — A booming success

Space X is on a roll with its launch of the Falcon 9 rocket early Monday, sending its robotic Dragon spacecraft speeding toward the International Space Station (ISS) with a critical space station docking port.

Rat heart muscle used to make robot stingray

An artificial stingray has been made by technologists and its ‘heart’ is cardiac muscle extracted from a rat. Light is used to cause the heart muscle to contract, thereby creating movement.

Mice mutated to become ‘super sniffers’

Scientists in the U.S. have undertaken experiments on mice, with the aim of using the rodents to sniff out drugs, explosives and other items required for national security.

Will three-parent genes increase life expectancy?

Studies using mice, where pups have been born with genes from three parents, have shown that the mice live longer. Scientists are discussing whether such a longevity effect would be seen with people.
