Magnets facts you should know

Here are some of the most interesting Magnets facts you should know

• Magnets are objects that produce an area of magnetic force called a magnetic field.
• Magnetic fields by themselves are invisible to the human eye.
• Iron filings can be used to show magnetic fields created by magnets (such as in the picture to the right).

• Magnets only attract certain types of metals, other materials such as glass, plastic and wood aren't attracted. That might be one of the most awesome random facts ever.
• Metals such as iron, nickel and cobalt are attracted to magnets.
• Most metals however are not attracted to magnets, these include copper, silver, gold, magnesium, platinum, aluminium and more. They may, however, magnetize a small amount while placed in a magnetic field. How much do you know about tiger facts for kids? Let’s check.
• Magnetism can attract magnetic objects or push them away. Magnets have a magnetic north pole and a magnetic south pole. If the same pole of two magnets are placed near each other they will push away (repel), while if different poles are placed near each other they will pull together (attract).
• Magnetic objects must be inside the magnetic field to respond, which is why you may have to move a magnet closer for it to have an effect.

• The Earth's core is believed to be a mix (alloy) of iron and nickel, giving the Earth its own magnetic field.
• The Earth's magnetic field is responsible for deflecting the solar wind, charged particles that come from the Sun.
• Magnetic compasses use the Earth's magnetic field to help navigate in north, south, east and west directions. Learn more about amazing science facts via our articles.
• Electromagnets are created by an electric current running through a surrounding coil. They have many uses including the generation of electricity in hydroelectric dams.

Porpoises facts you may have never heard of

Right here in this article, you can learn about all your favourite mamals, and even some you may have never heard of Porpoises

• Porpoises are among the smallest aquatic mammals. Check out my list of fun, weird and just plain amazing fact of life I have found.
• They are related to dolphins and whales and belong to the same order, Cetacea.
• They are very similar looking to the dolphin. However, the way to distinguish them generally is from: their smaller size; they have a rounder body shape and they lack the ‘beak’ of the better known dolphins.
• There are six species of porpoise.
• Different types of porpoises include the Common or Harbour porpoise, which is dark coloured on back and white underside, for camouflage in coastal waters and is similar to the Californian porpoise; Dall’s porpoise, which has a slightly more muscular body, they are jet black on back with white patches on the belly and flanks; Burmeister’s porpoise, which is dark overall, the Dorsall (back) fin has a sharp point with ‘teeth’ on its leading edge; Finless porpoise, which are grey overall, except for paler throat and face, they have a rounded, blunt head and no dorsal fin; the Spectacled porpoise, which is blue-black on back and white on sides and under-parts, they have a rim around their eyes which resemble spectacles. That might be one of the most awesome interesting facts ever.
• Porpoises are thought to have emerged as a group of aquatic mammals about 15 million years ago, when they were confined to the north of the Pacific Basin. From these beginnings they slowly evolved into the total of six species of porpoise alive today.
• They are sociable creatures and are often found in groups of 2-20, but usually about 4.
• They are sexually mature by the age of 4-7 years, according to the species. mating season is summer in the northern hemisphere. Gestation is 11-12 months and they have 1 young.
• Young calfs are born half the length of the female and has to be brought to the surface immediately to take its first breath. The female often swims on her side as she suckles her young calf. In this way they reach the water’s surface to breathe at the same time. This only happens in the first few days after birth, and soon the calf surfaces independently and dives to resume feeding. The young often remain with its mothers after being weaned.
• The Dall’s porpoise is known to be the fastest of all the porpoises. It powers through the water at speeds of 20-30km/h. It is also famous for its ‘rooster’ spray – a stream of water that arcs up over the head as it reaches the water’s surface. They are the most sociable and are attracted to moving ships.

• The Finless porpoise, as its name suggests, has no dorsal fin. The females have been known to carry her single young, or calf, on her back as on a saddle.
• Porpoises have between 60-120 teeth which are flattened into a spade shape at the tip.
• The common porpoise makes a distinctive, explosive noise as it comes to the surface to exhale.  It has also been called a ‘puffin pig.
• Similar to the dolphin, the porpoise have a wide repertoire of communication calls, including ‘clicks’ used for echo-location. That might be one of the most awesome animals facts you had no idea before.
• Their greatest threat to population is fishing nets and pollution. Some species are thought to be declining as a result. 
• Another hazard of inhabiting coastal waters for the common porpoise is that it can get stranded on beaches.

Top 9 awesome facts on Moose

This writing is so amazing. I just wanna all of you can enjoy top 9 awesome facts on Moose . Keep seeing to enjoy!

1. MOOSE ARE HUGE.

Moose are the largest members of the deer family, weighing as much as 1200 pounds; they can grow to be 5 to 6.5 feet from hooves to shoulders. This does not include a raised head or antlers, so it's safe to say that the majority of moose tower over all non-basketball players. 

Enjoy our wide range of funny pictures with captions that can make a joyful day.

2. THEY EAT A LOT.

With huge size comes a huge appetite. Moose are browsers and will casually devour 73 pounds a day in the summer and 34 pounds in the winter. They eat an assortment of shrubs, woody plants, and aquatic vegetation; in the winter, their diet is more restricted, so they eat the buds of plants.

3. ORGANISMS OF ALL SIZES POSE A THREAT TO MOOSE.

Moose are formidable opponents with sharp hooves that can kick with tremendous force, but even they have predators. A pack of wolves or a black bear is no match for a healthy adult moose, so bears and wolves typically pick off the young, sick, and old. And even though moose are powerful and quite large, a single bite can do one in: There's a good chance the bite will cause an infection that eventually kills the animal up to two weeks later. 

Moose also have a much smaller menace to worry about: parasites. Brain worm (Parelaphostrongylus tenuis) is a parasite contracted from eating snails. The infectious larvae migrate to the moose's brain and cause neurological damage. "It’s interesting thinking of something as big as a human hair killing a 1200 pound moose, but they do," Carstensen says. 

Another tiny nuisance is the winter tick. Tick infestations depend on the weather and habitat: Harsh winters mean less ticks the following year; when ticks fall off animals to complete their cycle and there's still snow on the ground, they die. So hard, long winters are great news for moose. 

4. THEIR ANTLERS ARE USED FOR FIGHTING...

When fighting off predators, the antlers, or paddles, don't come into play as much as you would think; a moose's first line of defense is its sharp hooves, which are capable of mortally wounding a wolf or bear.

Paddles are only found on males, and used mainly for fighting and displaying. During mating season in autumn, bulls will cover a lot of ground looking for females to mate with. They establish breeding territory by fighting off other males in the area. The fights are not always fight-to-the-death scenarios, and often a competing moose will back away from a fight if the challenger has a more impressive rack of antlers. Great paddles are not the only way to find mates; some males with better navigational skills—or just sheer luck—may come across a female by chance and completely skip antler combat. 

5. ...AND THEY SHED EVERY YEAR.

Moose lose their paddles every winter and grow new ones the following spring. "Antler growth is based on testosterone levels and day length," Carstensen says. "So they start to grow those antlers in the late spring and summer, and they’re covered in velvet. The velvet is vascularized so there is a blood-flow supplying these antlers as they’re growing." By early fall—a.k.a. mating season—bulls start to shed and shine their paddles by rubbing them against trees. Their fuzzy velvet-covered antlers go through a gory transformation, and by October they will have shiny new paddles for competition and display. 

Antlers are also a great indicator of age. With each winter, young moose paddles grow in size: nubs become spikes and spikes become full racks. Bulls in their prime, between ages 5 and 8, have the largest racks. With old age, the antlers become more deformed and less impressive. 

6. ANTLERS ARE HEAVY. 

Just like the moose themselves, antlers can come in different sizes. The paddles are essentially a big bone, so they generally weigh quite a bit; bulls develop muscular necks to help hold up the enormous paddles. A full grown moose's antlers can weigh about 40 pounds. Anyway, this may be one of the most fascinating animal facts until now.

7. THE BABIES NEED HELP FROM THEIR MOM.

Female moose, or cows, generally have 1 to 2 calves in May. On average, the calves weigh about 30 pounds at birth and grow very quickly. Still, baby moose don't have the ability to run or protect themselves very well, so the mother stays with her offspring for a year and a half, fighting off wolves and bears that try to pick off the young calves.

8. THEY'RE GREAT SWIMMERS.

Moose are naturally gifted swimmers. It's common to see one hop right into a lake and swim across at up to 6 mph. The animals have an innate ability to know how to swim, so even calves can swim. 

9. THERE ARE FOUR SUBSPECIES IN NORTH AMERICA.

Moose can be categorized into four different species in North America: the eastern moose (A. alces americana), the Shiras moose (A. alces shirasi), the Alaskan moose (A. alces gigas), and the northwestern moose (A. alces andersoni), which Carstensen works with in Minnesota. Moose can be distinguished by different sizes and antler shapes. The largest moose is the Alaskan moose (pictured above) that can stand at 7 feet tall with an antler span of 6 feet. 

10. THEY'RE DYING AT AN ALARMING PACE.

Something is happening to all the moose in Minnesota. The state once had a flourishing moose population in the north that was hunted and doing quite well: In the mid-1980s, there were 2000 of the animals in the northwest, but that number dropped to less than 200 in just two decades. This prompted the state to do some research to prevent further drops in population. Unfortunately, the northeast is now facing similiar a problem; the moose population has dropped 50 percent since the mid-2000s.

How many facts did you know about Greater Bilby?

How many facts did you know about Greater Bilby?

Greater bilbies are commonly known as bilbies due to the lesser bilby now being extinct. They are marsupials found only in Australia and are also called rabbit-eared bandicoots. The Easter Bilby is an Australian alternative to the Easter Bunny.

Facts About Greater Bilby 

• The greater bilby comes from the family of marsupials known as bandicoots. It is the largest among all the members of the family.
• According to the AustralianNationalUniversity, the animal has derived its name from an aboriginal language ‘Yuwaalaraay’.
• Its black coloured eyes, nearly 1 centimetre in diameter, do not make clear vision. Due to the poor vision, it solely relies on its strong sense of hearing and smell. The eyes are protected with the help of fine black eyelashes. This is one of the most interesting facts about Greater Bilby ever. 
• Built of a greater bilby comprises of long pointed nose, large hairless ears, white underside, black tail with a white crest. Because of its large ears, it is also known as Rabbit-Eared Bandicoot.
• The large ears of bilby aid in its effective hearing, as well as, strive to regulate its body temperature. They are also exceptionally manoeuvrable and can be rotated, made to stand flat against the body, positioned at right angles to the body and can even be folded in half.
• The soft and silky fuzz of bilby is primarily of pale blue-grey colours, with white and cream coloured undersides and feet.
• The stretched nose with hairless pink tip gives bilby an ability to smell sharply and smartly. You can witness many long, dark fuzz stick out from either side of the snout.
• A bilby has long slim tongue and 48 teeth: 26 on upper jaw and 22 on lower.
• It has slightly curved claws on the toes of its front feet. Whereas, on the feet of its hind legs, the second and third toes have slight joints with much larger fourth toe.

• Its claws and front legs are very strong which help it dig for its food and make deep burrows. An expert in digging, a bilby can dig up to a dozen of burrows. These burrows are generally spiral and as much as 3 meters deep.
• When a female bilby digs the soil, the dirt does not fill in its pouch as the pouch of a bilby opens in backward direction.
• The weight of an adult male bilby can go up to 2.5 kg. The weight of adult female bilby on the other hand, is significantly less (sometimes half) than that of an adult male.
• These are the nocturnal creatures that came out of their burrows nearly an hour after sunset and often go back in their burrows before first rays of the sun.
• The tail of a bibly is divided into three distinct sections: in the begining for a few centimetres, the colour of the tail resemble blue-greyish colour of the body; the middle section of the tail is black coloured, and at the end the tail is white.
• Bilby is a solitary animal, which prefers to roam alone. Although sometimes, bilbies are also seen in groups with at the most four members.
• Given that there is sufficient rainfall and food is available to them, bilbies can breed throughout the year. Let’s discover some interesting science facts that will amaze you.
• Having the smallest gestation period of all the mammals, greater bilbies breed one to three young bilbies in a litter.
• Infant bilbies remain in the pouch of their mother for nearly 80 days. It takes further 2 weeks till they become independent.
• Bilbies are the omnivorous creatures. Their food ranges from seeds, fruits, fungi to spiders, bulbs, small animals, insects and their larvae.
• A greater bilby consumes significant amount of mud along with its food.
• Bilbies do not drink water; rather, their food provides them with the requisite level of water to survive.
• Previously, they were hunted by Australians for food and fur. Other than humans, today they are preyed by foxes and feral cats.
• Before the European settlement, nearly 70% of the Australian Mainland had bilbies.
• At present, they are mostly seen in the south-west Queenslandand secluded parts of Western Australiaand the Northern Territory.
• The isolations of each of their colonies make them even more susceptible to diseases and inbreeding.

10 of the most interesting facts on Gibbon

Check out below 10 of the most interesting facts on Gibbon right here

Gibbon is a small ape. Its closest relatives are gorilla, chimpanzee, orangutan and bonobo. There are 15 species of gibbons that can be found in Southeast Asia (China, India, Burma, Malayan peninsula, Borneo…). Gibbon lives in dense jungles and tropical rainforests.

Gibbon facts

1. Gibbons spend almost all of their time in the treetops of the rainforest. They even sleep there, resting in the forks of branches.
2. Their dramatic form of locomotion, called brachiating, can move gibbons through the jungle at up to 35 miles (56 kilometers) an hour, bridging gaps as wide as 50 feet (15 metres) with a single swinging leap.
3. Because they are not able to swim, different types of gibbons are isolated in different areas by large rivers.
4. When gibbons walk, whether along branches or in the rare instances when they descend to the ground, they often do so on two feet, throwing their arms above their head for balance.
5. They are the most bipedal of all non-human primates and are often studied for clues to what evolutionary pressures may have led to human walking.
6. There are 15 recognized species of gibbons ranging from northeastern India to southern China to Borneo. Let’s discover some interesting science facts that will amaze you.
7. Gibbons are omnivores (they eat both plants and animals). Their diet consists mainly of fruit, but they also eat different types of seed, shoots, flowers and insects.
8. Gibbons live in family groups composed of breeding couple and their offspring. Gibbons are monogamous (one couple mate for life) and they form very strong bonds with family members. Grooming plays important role in their social life.
9. Gibbons are territorial animals that usually live on a territory of 25 to 40 hectares. They fiercely defend their home.
10. Gibbons are highly intelligent animals. They can recognize themselves in the mirror. Also, they are able to communicate via various songs. Songs usually last 10 to 30 minutes and both males and females perform them. Main purpose of the song is to announce presence of the group on a certain territory.

Nightmare Machine know what scares human

Keep reading for more interesting information about Nightmare Machine know what scares human

The idea of artificial intelligence (AI) — autonomous computers that can learn independently — makes some people extremely uneasy, regardless of what the computers in question might be doing.

Those individuals probably wouldn't find it reassuring to hear that a group of researchers is deliberately training computers to get better at scaring people witless.

The project, appropriately enough, is named "Nightmare Machine." Digital innovators in the U.S. and Australia partnered to create an algorithm that would enable a computer to understand what makes certain images frightening, and then use that data to transform any photo, no matter how harmless-looking, into the stuff of nightmares.

The idea of artificial intelligence (AI) — autonomous computers that can learn independently — makes some people extremely uneasy, regardless of what the computers in question might be doing.

Those individuals probably wouldn't find it reassuring to hear that a group of researchers is deliberately training computers to get better at scaring people witless.

The project, appropriately enough, is named "Nightmare Machine." Digital innovators in the U.S. and Australia partnered to create an algorithm that would enable a computer to understand what makes certain images frightening, and then use that data to transform any photo, no matter how harmless-looking, into the stuff of nightmares. [5 Intriguing Uses for Artificial Intelligence (That Aren't Killer Robots)]

Images created by Nightmare Machine are unsettling, to say the least. Iconic buildings from around the world appear eroded and distorted within shadowy settings or amid charred and smoldering landscapes, glimpsed through what appears to be murky, polluted water or toxic gas clouds.

Nightmare Machine's faces are equally disturbing. Some of the subjects are almost abstract, but subtle — creepy suggestions of hollow eyes, bloody shadows and decaying flesh still cause unease. Even the lovable Muppet Kermit the Frog emerges from the process as a zombie-like creature that would terrify toddlers — and adults, too.

The primary reason for building Nightmare Machine was to explore the common fear inspired by intelligent computers, its trio of designers told Live Science. They wanted to playfully confront the anxiety inspired by AI, and simultaneously test if a computer is capable of understanding and visualizing what makes people afraid.

"We know that AI terrifies us in the abstract sense," co-creator Pinar Yanardag, a postdoctoral researcher at MIT Media Lab in Massachusetts, wrote in an email. "But can AI scare us in the immediate, visceral sense?"

The designers used a form of artificial intelligence called "deep learning" — a system of data structures and programs mimicking the neural connections in a human brain — to teach a computer what makes for a frightening visual, according to co-creator Manuel Cebrian, a principal research scientist at CSIRO Data61 in Australia.

"Deep-learning algorithms perform remarkably well in several tasks considered difficult or impossible," Cebrian said. "Even though there is a lot of room for improvement, some of the faces already look remarkably creepy!"

Once deep-learning algorithms understood the visual elements that were commonly perceived as spooky, they applied those styles to images of buildings and human faces — with chilling results

"Elon Musk said that with the development of AI, we are 'summoning the demon,'" co-creator Iyad Rahwan, an associate professor at MIT Media Lab, told Live Science about science facts.

"We wanted to playfully explore whether and how AI can indeed become a demon, that can learn how to scare us, both by extracting features from scary images and subsequent refinement using crowd feedback," Rahwan said. He added that the timing of their spooky experiment — close to Halloween — was no accident. It may be one of the most awesome infor from factoflife we’ve enjoyed.

 

"Halloween has always been a time where people celebrate what scares them," he said, "so it seems like a perfect time for this particular hack." 

"Our research group's main goal is to understand the barriers between human and machine cooperation," Rahwan said. "Psychological perceptions of what makes humans tick and what makes machines tickare important barriers for such cooperation to emerge. This project tries to shed some light on that front — of course, in a goofy, hackerish Halloween manner!"

And if you're brave enough, Nightmare Machine could use your help to learn how to become even scarier.

The project's creators used deep-learning algorithms to generate frightening images of dozens of faces, tweaking the results to make them look even more disturbing. Nightmare Machine visitors can vote on these so-called "Haunted Faces," to help the algorithm "learn scariness," according to instructions on the website.
