Scientists said on Tuesday that they had discovered the world’s first hybrid sharks in Australian waters, a potential sign the predators were adapting to cope with climate change.
The mating of the local Australian black-tip shark with its global counterpart, the common black-tip, was an unprecedented discovery with implications for the entire shark world, said lead researcher Jess Morgan.
“It’s very surprising because no one’s ever seen shark hybrids before, this is not a common occurrence by any stretch of the imagination,” Morgan, from the University of Queensland, told AFP.
“This is evolution in action.”
Colin Simpfendorfer, a partner in Morgan’s research from James Cook University, said initial studies suggested the hybrid species was relatively robust, with a number of generations discovered across 57 specimens.

Spider-Man’s webbing is something that researchers have been trying to reproduce for decades
US researchers have created silkworms that are genetically modified to spin much stronger silk.
Writing in the PNAS journal, scientists from the University of Wyoming say that their eventual aim is to produce silk from worms that has the toughness of spider silk.
In weight-for-weight terms, spider silk is stronger than steel.
Comic book hero Spider-Man generated spider silk to snare bad guys and swing among the city’s skyscrapers.
Researchers have been trying to reproduce such silk for decades.
But it is unfeasible to “farm” spiders for the commercial production of their silk because the arachnids don’t produce enough of it – coupled with their proclivity for eating each other.
Silk worms, however, are easy to farm and produce vast amounts of silk – but the material is fragile.
Researchers have tried for years to get the best of both worlds – super-strong silk in industrial quantities – by transplanting genes from spiders into worms. But the resulting genetically modified worms have not produced enough spider silk until now.

(NaturalNews) If you read the ingredients label on a loaf of bread, you will usually find an ingredient listed there as L-cysteine
. This is a non-essential amino acid added to many baked goods as a dough conditioner in order to speed industrial processing. It’s usually not added directly to flour intended for home use, but you’ll find it throughout commercial breads such as pizza dough, bread rolls and pastries.While some L-cysteine is directly synthesized in laboratories, most of it is extracted from a cheap and abundant natural
protein source: human hair
Within five years, a woolly mammoth will likely be cloned, according to scientists who have just recovered well-preserved bone marrow in a mammoth thigh bone. Japan’s Kyodo News first reported the find. You can see photos of the thigh bone at this Kyodo page.
Russian scientist Semyon Grigoriev, acting director of the Sakha Republic’s mammoth museum, and colleagues are now analyzing the marrow, which they extracted from the mammoth’s femur, found in Siberian permafrost soil.
