Poisonous alkaloids in blue dart frogs' skin are absorbed from ants they eat in the wild. In captivity, the frogs eat mainly crickets and fruit flies and actually lose their toxicity.

The World Health Organization threw everyone into a panic by releasing a report categorizing red and processed meat as cancer-causing agents. But although yes, there is a link, the risk is still incredibly small.

The X ray dye makes it easier to see the organs and blood vessels when the pictures are developed. The intravenous contrast material is used for chest or pelvic scans, while oral-contrast material is used for abdominal scans.
The CT scanner is made up of several computer systems, including the host computer, which organizes the entire process. One computer converts the raw data into an image, while another lets the technician control the gantry.
Tissues such as those found in the brain are less dense and appear grey. Images that appear black denote organs such as lungs or others that can fill with air.
Even at 10%, the high possibility of life is overwhelming. There are at least a few hundred billion stars in our galaxy, which means that around 20 to 40 billion planets have the potential for the development of organisms.
The comparisons between the Earth and Gliese 581g should not be overstated, however. Even if Gliese 581g can sustain organisms, it would be a very different place to live.
Gliese 581c skims the near side of the habitable zone, but scientists suggest that it does not have enough of a toehold in this zone to provide a stable infrastructure for organic formations.
Planets that grow beyond 10 times the size of the Earth tend to become gaseous and uninhabitable, without the solid or liquid infrastructure necessary for organisms.
Like the Earth, Gliese 581g is also the right size for organic life. It is about 3.1 to 4.3 times the size of the Earth, and this relatively low mass means it should be made mostly of rock.
Firstly, Gliese 581g is located at almost exactly the right distance from its red dwarf parent star (Gliese 581) in order to sustain liquid water, which is the only known criterion for organic formation.
Although we currently know very little about Gliese 581g, a couple of its features strongly indicate that this planet might harbor the existence of organisms.
More recently, scientists have joined in on the collective wonderment after the first discovery by astronomers of a new planet - Gliese 581g - that could almost certainly support extra-terrestrial organisms.
Kathy, Ruth, and Tommy are clones, created in a laboratory and raised to provide donor organs to severely ill patients. This dystopian drama is about the love triangle between them.
Scientists say that Neanderthals matured more rapidly than homo sapiens, living fast and dying young. By aging slower, humans had more time to organize socially and learn.
Flashlight fishes are named for their large bioluminescent organs that are located beneath the eyes. The light they produce is used to attract prey, escape from predators, and to communicate!

Resistance to antibiotics poses a "major global threat" to public health. The World Health Organization described a "post-antibiotic era", where people die from simple infections that have been treatable for decades.
Imagine your heart is failing. Thankfully there's a donor, but it's not human. It's a pig. We're close to successfully transplanting non-human organs, but such procedures raise thorny issues about what it means to be human.

While taxonomists—scientists who describe and name species—try to bestow names descriptive of the new organism, there is also ample evidence that they like to have fun with their task.
