Do male seahorses get pregnant?
In sea horses, the males become pregnant. Their mating involves the female inserting her oviduct into the male's brooding pouch. She does this several times for short intervals to avoid exhaustion. In between the female rests while the male contorts himself to try to get the eggs in place in his brood pouch.

Who discovered the vaccine for polio?
Jonas Salk. Jonas Edward Salk (October 28, 1914 – June 23, 1995) was an American medical researcher and virologist. He discovered and developed the first successful inactivated polio vaccine. He was born in New York City to Jewish parents.

What causes dimples in the cheeks?
Dimples are caused by an abnormally short facial muscle. The zygomaticus major, a facial muscle, is attached to the skin of your cheeks. Dimples appear when the muscle pulls hard enough on your cheeks to cause visible indentations on your face. This usually occurs when we speak or smile, when the muscle is contracting.

Do sea otters have pockets?
Under each foreleg, the sea otter has a loose pouch of skin that extends across the chest. In this pouch (preferentially the left one), the animal stores collected food to bring to the surface. This pouch also holds a rock, unique to the otter, that is used to break open shellfish and clams.

Who flew the first plane in the world?
Orville and Wilbur Wright designed and flew their Flyer plane in December 1903. Five people were said to have witnessed the flight including John T. Daniels who took photographic evidence. Claims that Whitehead beat the Wright Brothers to the record first emerged in 1937.

Do starfish have a brain?
The nervous system of the starfish is very simple...there is no brain and there are not even any ganglia to coordinate movement. The nervous system is characterized by a nerve ring that surrounds the mouth. A radial nerve branches off of the nerve ring and extends to each arm.

Is blue eyes a mutation?
New research shows that people with blue eyes have a single, common ancestor. A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye colour of all blue-eyed humans alive on the planet today.

Can you go blind from looking at a solar eclipse?
While it may be tempting to brush off warnings against looking up at this eclipse bare-eyed, don't: The light of an eclipse really can damage your eyes — though warnings of total blindness are likely overstated. The condition is called solar retinopathy, and it occurs when bright light from the sun floods the retina.

What countries border the Black Sea?
The Black Sea is an inland sea located between far-southeastern Europe and the far-western edges of the continent of Asia and the country of Turkey. It's bordered by Turkey, and by the countries of Bulgaria, Romania, Ukraine, Russia and Georgia.

Which planet has the hottest surface temperature?
Venus, the second closest plant to the Sun, has the highest average temperatures of any planet in our Solar System, regularly reaching temperatures over 460°C. Venus is so hot because of its proximity to the Sun and its thick atmosphere.

How many moons does Mars have?
Mars has two moons, Phobos and Deimos, which are thought to be captured asteroids. Both satellites were discovered in 1877 by Asaph Hall and are named after the characters Phobos (panic/fear) and Deimos (terror/dread) who, in Greek mythology, accompanied their father Ares, god of war, into battle.

Are genes located on chromosomes?
In genetics, a locus (plural loci) is the specific location of a gene, DNA sequence, or position on a chromosome. Each chromosome carries many genes; humans' estimated 'haploid' protein coding genes are 20,000-25,000, on the 23 different chromosomes.

Who was the designer of the Olympic rings?
The primary symbol of the Olympic Games is composed of five interlocking rings, colored blue, yellow, black, green, and red on a white field, known as the "Olympic rings." The symbol was originally designed in 1912 by Baron Pierre de Coubertin, co-founder of the modern Olympic Games.

Who first proposed the theory of evolution by natural selection?
In the early 19th century, Jean-Baptiste Lamarck proposed his theory of the transmutation of species, the first fully formed theory of evolution. In 1858, Charles Darwin and Alfred Russel Wallace published a new evolutionary theory that was explained in detail in Darwin's On the Origin of Species (1859).

Which is the largest carnivorous land animal?
Today's large carnivorous land mammals, including the record-setting polar bears—which usually weigh around half a ton but can grow to weigh nearly a ton, are threatened in part because of the energy intake-and-expenditure equation, Carbone told LiveScience.

What time period are we in?
In geochronology, an epoch is a subdivision of the geologic timescale that is longer than an age and shorter than a period. We are currently living in the Holocene Epoch of the Quaternary Period. Rock layers deposited during an epoch are called a series.

How much does the temperature change with altitude?
Although the actual atmospheric lapse rate varies, under normal atmospheric conditions the average atmospheric lapse rate results in a temperature decrease of 6.4C°/km (3.5F°/1,000 ft) of altitude above ground level. The measurable lapse rate is affected by the moisture content of the air (humidity).
