Half granny, half delicious
|
view preview
A one in a million apple has been found on a property in Kingston in southern Tasmania. Half granny smith, half red delicious, it's thought that this mutation is the result of all the mutations that led to the Australian royal red gala, and this particular apple is trying to revert to a couple of its previous versions.

Try dates, not honey
|
view preview
While they are super sweet, syrup made from this ancient fruit has antibacterial compounds that are more effective than honey. In case you've never had it or seen it before, dates are a thick, dark brown, and super-sweet fruit used in Middle Eastern cuisine. New research suggests that date syrup contains chemical compounds that help ward off a number of bacterial infections, including those caused by Staphylococcus aureus and Escherichia coli. This was discovered after scientists inhibited the growth of these pathogens for about six hours, which researchers say is faster than manuka honey - a honey known for its antibacterial and wound healing properties. ...

Spiders smaller than a grain of sand
|
view preview
Two new species of spiders have been discovered in China, and neither of them are bigger than a grain of sand. They live in the damp litter of the forest, which is why they had gone unnoticed for so long. Both species are part of the Mysmenidae family, which are somewhat poorly understood orb-weaving spiders. Mysmena wawuensis (top) measures 0.75 mm, while Trogloneta yuensis (bottom) is 1.01 mm.

The plastisphere
|
view preview
Much of the debris in our oceans consists of small fragments of detritus no larger than a fingernail. These confetti-like plastic pieces act as microbial reefs – their own ecosystems – in the vast open ocean. Scientists are studying them to help better understand the predation and symbiosis in these mini ecosystems themselves and also how they are affecting the ocean and its other communities on a broader scale.

House plants could one day power our computers
|
view preview
Researchers have discovered a novel method to harness photosynthesis to create electricity. By attaching nanotubes to plant cells, the researchers were able to direct the electrons that plants free during photosynthesis down a wire and generate electrical current – and it was twice as powerful as electricity gathered from solar cells.

When Henry Molaison (now widely known as H.M.) cracked his skull in an accident, he began blacking out and having seizures. In an attempt to cure him, daredevil surgeon, Dr. William Skoville, removed H.M.'s hippocampus. Luckily, the seizures did go away — but so did his long-term memory!

Underwater world
|
view preview
Near the town of Tragöß in Styria, Austria you can find this stunning lake known as Grüner See (Green Lake). Named Green Lake for its amazingly clear emerald green water it’s mostly the result of seasonal snowmelt from the surrounding Hochschwab Mountains and forests. During winter months the lake is only 1-2m deep with the rest of the area used as a county park, however as spring arrives the lake grows in size from all the melting snow reaching at its peak around mid-May 12m deep in places. Not surprisingly the waters are a little chilly at 6-7oC, although it remains popular among divers during the peak months who love to pose on the underwater bench and visit the flooded green meadows. ...
