Suicide prevention from a blood test

By identifying the bio-markers that show a heightened risk of suicide, doctors would be able to treat the condition, potentially saving the individual’s life. When the blood test is combined with clinical analysis of mental state, researchers were able to identify people with suicidal tendencies over 80% of the time.

It is important to note that this technique is still in the early stages and more extensive testing will be required before it can be used clinically.

Your DNA is flame_retardent

Italian researchers have found a new use for DNA: as a flame retardant. Coating cotton cloth with extracted DNA, the scientists found that the genetic material reduced the fabric’s flammability.

When heated, DNA’s phosphate-rich backbone produces phosphoric acid, which helps replace water in cotton fibers with a flame-retarding residue. At the same time, the bases, which contain nitrogen, produce ammonia, which inhibits combustion and interacts with the residue to form a protective shield over the cloth.

why hands and feet get wrinkled after too much time in water?

The wrinkles that form on people’s hands and feet after soaking in water may have evolved to help humans handle wet objects more efficiently.

Heart can also look like this ;)

This stunning image shows a magnified 3D scan of the heart of a fruit fly. Drosophila pump blood through their bodies with a long, tube-shaped muscle.

The only known fluorescent vertebrate

The proteins do not fluoresce through a chromophore like other animals. Instead, it only emits light when bound with bilirubin, which is toxic to humans in large quantities. This protein could be used to better diagnose diseases like jaundice and anemia.

What ants eat!!..is easily recognized

If you haven’t seen these yet, they’re good fun!

Mohamed Babu from India, captured these amazing pictures last year after his wife noticed that ants turned white when they drank milk.
He dissolved sugar in food colouring solutions of red, green, blue and yellow and then placed them in his garden to attract ants. Some of them even moved between the different solutions, resulting in psychedelic colour combinations.

Long-horned spider

Familia: Araneidae
Subfamilia: Gasteracanthinae
Genus: Macracantha
Species: Macracantha arcuata

Long-horned orb-weaver spider lives predominantly in primary forest. The purpose of their disproportionately long body horns remains a mystery.

The fastest animal of palnet

Cheetahs run at about 104 km/h (64 mph) –that’s almost three times faster than some of the world’s top sprinters, who usually max out at 37.6 km/h (23.4 mph).

The aquatic beauty

The beautiful Crown Jellyfish (Netrostoma setouchina) has a deep groove running around the bottom of the umbrella, giving them the appearance of a crown.

Some cool info:
♦ Jellyfish are 95% water.
♦ They have no heart, brain, blood, or gills.
♦ The body of the Jellyfish is called a bell.
♦ Their tentacles and arms are around their mouth.
♦ They use their tentacles to help sense and catch fish, shrimp, and zooplankton.
♦ They have roamed the seas for at least 500 million years.
