Can you guess what animal this is?

Imagine a battery the size of the one in your cell phone with enough juice to jump-start a car. It's actually not too far-fetched. Scientists at the University of Illinois have been developing microbatteries. Only a few millimeters long, these batteries may pave the way for electronics to become smaller and thinner, while still providing enough energy to be highly effective. The best part is that it recharges 1000 times faster than current batteries. Good things do come in small packages ...

This is a close up of a llama eye. The strange "ruffles" are called 'iridic granules' (corpora nigra) and they are used to to shade the eye from bright sunlight. In bright light these iridic granules can actually interlock to completely cover the centre of the pupil. This leaves just two holes open on either end of the pupil, reducing the amount of light that can enter the eye. These odd looking structures are also found in horses, cattle and sheep.

There are over 12,000 species of ants in the world, and a new tree of life has been published to better understand how they are all related. Their evolutionary origins have been traced to the tropics in South America, where they play a critical role in maintaining the health of the ecosystem.

Listeria bacteria has been enlisted by researchers to selectively infect metastatic pancreatic cancer cells and deliver radioisotopes into them. The experimental treatment dramatically decreased the number of metastases (cancers that have spread to other parts of the body) in a mouse model of highly aggressive pancreatic cancer without harming healthy tissue. Mice livers are shown above. The saline control liver on the left presents a large number of metastases compared to the liver on the right which was subject to the radioactive Listeria treatment. ...

A Judean date palm plant was planted in 2005 using seeds that were hidden away for 2000 years. While other species of date palms thrive around the world, this particular species was thought to be extinct for 1800 years.

Date palms are either male or female, and this one, nicknamed Methuselah, is a male, so it will not produce fruit. However, the plant is alive and well, and is the oldest known seed to successfully germinate.

Brain electronic interfaces can make a blind person to see, a deaf person to hear, and help people to increase their memory capacity.

Human babies and mouse pups both automatically and deeply relax when carried by their mums, new research has revealed. The study showed the babies' heart rates slowed down and their nervous and motor systems relaxed when they were carried, suggesting it doesn't just feel good, its an essential mother-infant interaction.
