Sunflowers like no other plant. Native to North America, sunflowers are heat-tolerant, resistant to pests, and simply beautiful

An annual plant, sunflowers have big, daisy-like flower faces of bright yellow petals (and occasionally red) and brown centers that ripen into heavy heads filled with seeds.

They are heliotropic, which means that they turn their flowers to follow the movement of the Sun across the sky.

Tall and coarse, the plants have creeping or tuberous roots and large, bristly leaves. Some sunflowers grow to over 16 feet in height, though there are also varieties today that have been developed for small spaces and containers.

Antarctica: Thousands of emperor penguin chicks wiped out

Thousands of emperor penguin chicks drowned when the sea-ice on which they were being raised was destroyed in severe weather.

The catastrophe occurred in 2016 in Antarctica's Weddell Sea.

Scientists say the colony at the edge of the Brunt Ice Shelf has collapsed with adult birds showing no sign of trying to re-establish the population, according to BBC.

And it would probably be pointless for them to try as a giant iceberg is about to disrupt the site.

The dramatic loss of the young emperor birds is reported by a team from the British Antarctic Survey (BAS).

Island lizards are expert sunbathers, and researchers find it's slowing their evolution

If you've ever spent some time in the Caribbean, you might have noticed that humans are not the only organisms soaking up the sun. Anoles -- diminutive little tree lizards -- spend much of their day shuttling in and out of shade. But, according to a new study led by assistant professor Martha Muñoz at Virginia Tech and Jhan Salazar at Universidad Icesi, this behavioral "thermoregulation" isn't just affecting their body temperature. Surprisingly, it's also slowing their evolution, according to Science Daily.

Sore knee? Maybe you have a fabella

A little bone in the knee scientists thought was being lost to evolution seems to be making a comeback, say experts.

The fabella is found in some people buried in the tendon just behind their knee.

Doctors think it is entirely pointless, and you can happily live without it - many people do.

However, people who have arthritis appear more likely to be in possession of a fabella.

Game that trains your brain can boost your mental skills

A bizarre brain training game that can boost mental skills in less than an hour has been discovered by scientists.

It relies on an effect called neurofeedback, where brainwaves are monitored and positive reinforcement is given when a desired brain state is reached, according to Daily Mail.

In the case of this study, experts gave one group of volunteers positive feedback for imagining hand movements, while another were given incorrect positive feedback.
