Bloody trees
|
view preview
The dragon’s blood tree ( Dracaena draco) has a thick red resin that makes the plant appear to be bleeding when it is cut. These subtropical plants form huge umbrella-like canopies and can grow for hundreds of years, but they are currently listed as Vulnerable by the IUCN due to the trademark resin being used in traditional medicine, violin staining, and even for embalming the dead.

Embryonic leopard cub
|
view preview
This is what an embryonic leopard cub looks like in the womb. It's not a photograph, but a combination of three-dimensional ultrasound scans, tiny cameras and computer graphics used to create realistic representations of animal fetuses for a National Geographic documentary.

Mesolithic man
|
view preview
The genome of the 7,000-year-old hunter-gatherer has given scientists unprecedented insight into modern humans before the rise of farming, and overturns the popular image of light-skinned European hunter-gatherers. The DNA was taken from the wisdom tooth of the Mesolithic man and revealed he was probably lactose intolerant, had more difficulty digesting starchy foods than today's humans, and carried mutations that boost the immune system against nasty illnesses previously thought to only be introduced to humans by farm animals. ...

Culling of sharks for the sake of safety?
|
view preview
The culling policy aims to reduce shark attacks by killing white, bull and tiger sharks over 3 metres long off the coast of Western Australia. Research on previous culls reveal no scientific evidence that destroying sharks reduces attacks, and the cull has caused outrage from conservation groups. Two experts from the University of Western Australia explain: "Pre-emptively killing sharks is a response based on emotion rather than of scientific data."

Only species of bird with a bill longer than its body
|
view preview
The sword-billed hummingbird’s bill is actually longer than its entire body. As the sole species in the Ensifera genus, this hummingbird is found across South America. The bill can grow up to 14 cm, so these birds have to use their feet to groom themselves and typically rest with their bill pointed upward so they can balance.

My new favourite animal
|
view preview
Meet the guineafowl puffer ( Arothron meleagris), all puffed-up and poisonous to deter any would-be predators. Found throughout the Indo-Pacific and Eastern Pacific Oceans, this spotty species loves feeding on tiny marine invertebrates and the tips of coral.

Solar panels on the moon could one day power Earth
|
view preview
Architectural and engineering firm Shimizu plans to solve Earth's climate crisis by building a band of solar panels 400 kilometres wide along the entire 11,000-kilometre equator of the Moon. The energy generated will be beamed back to Earth in the form of microwaves and converted into electricity at ground stations. The team hopes to start building the "Luna Ring" from Moon materials in 2035.

Ladies, would you ever accept a black rose?
|
view preview
This is the very rare Turkish Halfeti rose. Although it looks like it's been spray painted, it's such a dark crimson colour that it looks pure black. The roses only grow during the summer in a Turkish village called Halfeti thanks to the unique soil conditions of the region and the pH levels of the groundwater. As they first bloom the flowers look dark red and fade to this black hue during the summer months.

World's newest island
|
view preview
The world's newest island, Niijima, keeps on growing, and is now eight times the size it was when it first emerged off the coast of Japan on 20 November. Having merged with its neighbouring uninhabited island, Nishino Shima - which sat 500 metres away in November - the pair bears an uncanny resemblance to Snoopy the cartoon dog.

Blue lava!
|
view preview
A volcano in Indonesia produces lava that looks BLUE! Though the molten sulfur looks red in daylight, during the night, the blue flames that reach heights of 5 meters (16 feet) are highly visible. The sulfur, which is right around its melting point at 115°C (240 °F), is pumped away from the volcano so it can cool and be collected by miners for 680 rupiahs per kilogram (about 2.5 cents per pound).

Super strong immune system
|
view preview
Pandas produce a super powerful antibiotic that kills bacteria and fungi. The substance is released by the panda’s immune system to protect them from catching infections in the wild. Researchers are trying to decode the substance’s makeup as it could be used to develop treatments against drug-resistant superbugs.
