Sea Slug Steals Photosynthesis Genes From Algae
The brilliant emerald green sea slug, Elysia chlorotica, spends months living on sunlight just like plants. It’s been called the photosynthesizing sea slug in the past, but how it manages to do this as well as it does is a complete mystery. In a new study appearing in the Biological Bulletin, researchers reveal that the sea slug has incorporated genes from the algae that it eats. |
Baby Chicks Count From Left to Right Just Like Us!
Newborn chicks associate numbers that have lower numerical values with the space to their left and higher numbers with their right. The findings, published in Science this week, suggests that the cute peeps may be using the same “mental number line” as we do. The tendency may be hard-wired. Wittle Turtles
Where do sea turtle hatchlings go once they reach the sea?
We know so little about the first 1-2 years of their lives that scientists called them the "lost years". New research has revealed where they go:http://bit.ly/1fR9TnQo edit. |
here frogfishy fishy fishy!
Frogfish are a variety of anglerfish that make up the family Antennariidae and can be found in tropical and subtropical waters.
They spend most of their time on the sea floor waiting for prey, which consists primarily of crustaceans and other fish. It begins to quietly stalk the prey by walking along the floor using its pectoral fins. When it is ready to strike, it rapidly opens its mouth to twelve times larger than normal, sucking up water and the fish. These frogfish typically have many projections coming off of their body, which helps give the frogfish camouflage. |
Poor pig nosed frog
Ugly animals need love too! A large proportion of conservation funds are allocated to animals that the general public would consider "cute". There is a now a campaign to convince people that less attractive animals, such as this pig-nosed frog, deserve our money and attention just as much as any panda. More info: http://bit.ly/19Yrcnh
these are fun guys!
There are more
than 70 species of bioluminescent fungi, mostly found in temperate and tropical areas of the world. 1. Mycena lux-coeli, 2. Mycena_chlorophanos, 3. Mycena illuminan, 4. Mycena lampadis More info: http://bit.ly/1aczsmZ |
fertility for all.
The woman, known only as Vali, is nearly 26 weeks pregnant with twins. She was previously rendered infertile by treatment for ovarian cancer. Doctors were able to produce two healthy eggs through transplanting her frozen ovarian tissue into her abdomen and then stimulating it with hormone treatment. This is the first time tissue has been successfully transplanted at an entirely different site in the body to where it was taken from.

fantastic mr foxThe ears of a fennec fox make it easy to identify, and they also play an important role in regulating body temperature. As the blood circulates through the large ears, it is cooled by the wind and helps cool down the body. This is an important adaptation for beating the heat in the Sahara Desert.

They have between 5 and 13 offspring at a time. Before birth, the female holds the embryos in the womb without a placenta. Instead, the embryos absorb nutrients from a yolk sac, and after the sac is depleted, the mother provides uterine "milk". Two female stingrays at the London Aquarium have given birth to young in spite of the fact that they haven't been near a male in more than two years. Therefore, it stands to reason that female stingrays have the ability to store sperm in some way. Watch a video of baby stingrays "dancing" here: http://bit.ly/13WSGul |
Holly hadrosaur!
The tail was discovered in northern Mexico and most likely belonged to a hadrosaur, a duck-billed dinosaur. The tail is 4.9 meters (16 feet) long and is made up of 50 vertebrae. Tails are rare finds, and this is the first discovered in such good condition.

I Heart you!The heart from a recently deceased donor is kept in a solution for about a week that dissolves everything except for the collagen and other structural cells.
Then, it can be repopulated with stem cells from the recipient, creating a perfect match. Of course, this technique is still in its infancy and is a long way off from being used to save patients. More info: http://bit.ly/1ahYz7E |
Surely not......The Midway Atoll is 1,200 miles away from civilization in the Pacific Ocean,
about halfway between North America and Asia. Millions of albatross that live there have been unknowingly snacking on garbage from the nearby Great Pacific Garbage patch. Of course, their bodies cannot process the plastic, and they eventually die. More info: http://bit.ly/14YIyPl go Sally!"Australian researchers have isolated an immune system cell in salamanders which helps it regenerate missing limbs and damaged organs — and they suspect the same thing could work in humans, too.
Salamanders, or axolotls, are unique among vertebrates in that they’ve got remarkable regenerative powers. Adults can literally regrow and restore function to any part of the body, including the spinal cord and heart — even parts of the brain. Moreover, the regenerated tissue is scar free; once repaired, the new tissue looks almost the same as it was before." More info: http://bit.ly/13K8vhx |

Species Discovery in 2012
The International Institute for Species Exploration has released their list of the top ten species discovered in 2012.
It includes a newly discovered species of African monkey, the smallest known frog, a carnivorous sponge, a bioluminescent cockroach and many more.Check out the full list here: http://bit.ly/Z5YpJw

injectable oxygen
Last year, a team of researchers in Boston developed a way to inject oxygen
directly into patients with an obstructed airway. This allows doctors time to
manage the problem of the blocked trachea while minimizing the risk of cardiac
arrest or brain injury. The trials are still ongoing for this amazing
technique.

Cool mantis
The Orchid Mantis of Southeast Asia lives among the flowers, as its pink and
white coloration and petal-shaped legs give it plenty of camouflage. The mantis
sits and waits until an insect comes to pollinate the flower, and then attacks
its prey. There are over 20 species of “Flower Mantises.”

3D Printing |
Over the last few months 3D printers being used to "print" biological cells and
tissues has hit the headlines in a major way. THIS ear is one step further
though - it actually contains the electronic components that would make it work
as a bionic sensory organ. It's the very first step towards printing or
manufacturing organs that behave and operate in the same way as the real thing.

crazy solar flare
(May 3rd) a relatively weak solar flare erupted from the Sun. Even this was
enough to trigger an absolutely STAGGERING plasma spire - the blue dot you can
see represents the approximate size of the Earth next to yesterdays plasma
eruption. It reached approximately 200,000 kilometers.
