Animal and Human Health

If you’re looking for the most amazing animal facts, you’re at the right place. Here is animal and human health relationship that can surprise you so much:

Animals play an important role in many people’s lives. In addition to seeing-eye dogs and dogs that can be trained to detect seizures, animals can also be used in occupational therapy, speech therapy, or physical rehabilitation to help patients recover. Aside from these designated therapeutic roles, animals are also valued as companions, which can certainly affect the quality of our lives. Is that companionship beneficial to our health?

The better we understand the human-animal bond, the more we can use it to improve people’s lives. 

This article summarizes what is known and not known about how animals help improve the health and well-being of people, and what the implications might be for helping people who don’t have pets of their own. Over 71 million American households (62%) have a pet, and most people think of their pets as members of the family. Some research studies have found that people who have a pet have healthier hearts, stay home sick less often, make fewer visits to the doctor, get more exercise, and are less depressed. Pets may also have a significant impact on allergies, asthma, social support, and social interactions with other people.

Penguins are birds but can't fly

Have you thought about this penguin facts mystery: Penguins are birds but can't fly? Do you want to have reasonable explaination for this? Keep reading

Like many birds, penguins must travel a long way between their feeding and breeding grounds. But rather than fly, they swim. It is a hard journey that has left biologists scratching their heads over why the birds did not keep their ability to fly as their diving ability evolved. A new study argues that birds cannot be both masterful divers and flyers, because flying abilities must weaken as the animals adapt to diving.

Rather than looking at penguins, a team led by biologist Kyle Elliott at the University of Manitoba in Winnipeg, Canada, examined species of diving seabirds that still have some ability to fly. These included the pelagic cormorant (Phalacrocorax pelagicus), a species that propels itself underwater with webbed feet, and the thick-billed murre (Uria lomvia), which flaps its wings underwater to swim.

The researchers tagged murres with recorders that measured the time of dives as well as depth and temperature, and cormorants with data-loggers that measured depth, temperature and acceleration changes during dives. They also injected isotope-tagged water into the birds. When the researchers tested the birds later, the tags enabled them to work out just how much carbon dioxide and water vapour the birds had expelled since the water was introduced, and thus to calculate the energy expended for diving and flying.

The team then compared their results to some that had already been collected for birds such as geese and penguins. They found that both cormorants and murres must spend exceedingly large amounts of energy to fly — the highest known among all flying birds.

When it came to diving, the energy costs for the foot-propelled cormorants were much higher than expected for a similarly sized penguin. The wing-propelled murres had diving costs lower than those of cormorants, but still 30% greater than those experienced by penguins of the same size. The results appear in the Proceedings of the National Academy of Sciences1.

The findings reveal a snapshot showing that murres are sitting on an evolutionary knife edge. Elliott and his colleagues speculate that because the wings of a murre are still built for flight, they create drag underwater. Furthermore, their small bodies, which are just light enough for them to take off, cool down more quickly than the bulkier bodies of penguins.

“Basically, they have to reduce their wings or grow larger to improve their diving, and both would make flying impossible,” says Robert Ricklefs, an ornithologist at the University of Missouri–St. Louis and co-author of the paper.

Life of sea stars in museum’s glass menagerie

See how interesting is it:

From 1863 to 1890, Leopold and Rudolf Blaschka made more than 10,000 sea creatures out of glass. There were anemones with tapered tentacles and pearled undersides, translucent jellyfish trailing the most delicate threads and feather stars more than worthy of their name despite their rigid composition. The intricate invertebrates, crafted by the father-son team at their studio in Dresden, Germany, were shipped across the world to serve as teaching models at universities and museums. In an era before marine surveys and underwater photography, before the rise of scuba diving resorts, the Blaschkas showed the world the wonders of the sea.

Over five dozen of their glass wonders are now on display at the Corning Museum of Glass in “Fragile Legacy.” Though the exhibit opens with glass eyeballs and a piece of jewelry — a nod to the Blaschkas’ pre-invertebrate business — the highlight is a darkened room set up like an aquarium, with sea creatures seemingly floating in blue. There’s a notable absence of museum placards and descriptions. “We really want people to look at the glassiness,” says Marvin Bolt, a curator of the exhibit, before pointing out the “Field Guide to Underwater Models.” The pamphlet contains each animal’s species name, as it was known in 1885 (when Cornell University acquired the pieces, now on loan to Corning) and as it is known today.
The Blaschkas combined stalks, pearls and a super thin barrel of glass to create this sea anemone, labeledBunodes crispa. While some glass was fused while hot, other pieces were attached once the glass had cooled.

Often the Blaschkas used other materials, such as paper, as seen in the webbing between this octopus’s tentacles. Different materials react differently to environmental conditions over time, creating a challenge for conservationists.

This oaten pipes hydroid, Tubularia indivisa, could easily be mistaken for a type of flower. The Blaschkas called the draping pearls “Tubularia grapes.”

Before creating their glass, the Blaschkas made detailed drawings from live organisms, shipments of semipreserved invertebrates and natural history texts. “The more they started making, the more well-known they became and the more access they were given,” says curator Marvin Bolt.

To create this sea cucumber, the Blaschkas glued glass dots onto the tubular body and then painted the body. The 15 tentacles surrounding the mouth help the creature feed

The aquarium offers a sense of the Blaschkas’ style, but it’s the room next door that provides the substance. Sketches and watercolors, bottles of colored powders, tweezers, pliers, scoops and wire, along with a demonstration video, give a fuller sense of how the Blaschkas did their work. Equally impressive are the matchboxes filled with kleine augen (“little eyes” in German) and other tiny but uniform component pieces, suggestive of an assembly line approach to handcrafting the final glass forms. A series of case studies explains how conservators stabilized the pieces, and a trailer for a related documentary, also titled Fragile Legacy, highlights the vulnerability, not of the glass, but of the real-world creatures living in warming seas.

China's upcoming super-secure Internet from space

The secret message sent by this method will be very difficult to read and intervention, brings many advantages in military and national trade for ownership.

China is preparing to build a super-secure version of Internet from space, according to The Sun. Beijing preparing to launch "satellite quantum" first in the world, is designed specifically to test new communication technologies.

Chinese experts believe that their work will spark an arms race office Monday when Russia, Europe and the United States is also vying to master this technology.

China's upcoming super-secure Internet from space

"Sure, I think there will be a race", Chaoyang Lu, a physicist at the University of Science and Technology of China, said. "If the first satellite launch goes well, China will definitely free up more".

Quantum technologies that someday will allow countries to communicate in absolute security. It works by firing tiny particles called protons from a great distance.

These protons are sent by a certain configuration to convey the message. These messages will be very difficult to read, and it is difficult to forge because any intervention also left traces.

Professor Lu believes that a network of 20 satellites will allow quantum China, or the competitors of these countries, providing secure Internet for the whole world.

Researchers at the University of Strathclyde in the UK is also working in this field, as well as the US NASA scientists. Which country will be the first successful military advantages and trade, because the ability to communicate completely confidential can help large enterprises as well as the army, navy and air force.

There is an "Internet stations" in space is also useful for monitoring activities, as it allows the spy "inspired" all over the earth with high-resolution cameras, and conceal tracking results is from the public and national enemies.

Dolphin massacre victims in Sri Lanka

For years, the dolphin massacre victims in Sri Lanka took place without any obstacles (?!). François Xavier Pelletier reporters during a fact brought evidence of the brutal disregard of international law.

Medium iron hook embedded deep in the flesh of the dolphin. It struggled, trying to get rid of that strange enemies. Animals were pulled aboard the ship, wriggling in pain in a pool of blood. Hissed the cries, dolphins like crying. Fisherman are preparing to take the blade ripped open the iron workers.

Sri Lankan fishermen despite the Europeans have to spend money to buy tickets to the pond to admire fishes have eyes like humans. For them, the "blue ocean" is a giant food warehouse. Moreover, they say dolphins are manatees.

Dolphin massacre victims in Sri Lanka

To learn more, François-Xavier Pelletier reporters together to sail with them. The trip that he almost did not return.

"I gave up a 10m long boat, on the radio that no buoys and rescue, only one old compass. They all rely on the same captain Gamini 3 fishermen "- Pelletier said. From the moment of departure, they had told him about the boat lost persons and the public did not know at, or on the fishermen drifted to the Marquises Islands and jailed.

In the middle of the cabin is a huge gazole tub, so we just can sleep 3 people in it, others tried to rest next to the engine. It cried loudly during 24/24. And hatches for containing ice. What I remember most is the smell of oil, the smell of fish to vomit on the boat flipped.

"Out of the 170 nautical mile coast, 2 times broken engine. With a boat like that, any other sailor will return to port. But this can not be obtained for Sri Lankan fishermen living by the sea, which only. Imagine my horror to learn that no one on the crew know about the latest machinery. I have to fix yourself, no choice than ".

"Like every evening, the crew cast nets to catch fish. One day, a storm arises, we have not seen during my 25 years at sea. White sea foam, waves covering up the boat. The only way the boat into the net column. If this wire is broken, the boat will be swept away like a reed. The fishermen kneel before the altar to pray and burn incense Buddha. The next morning, we found a dead dolphin caught by nets. Fishermen butchered it for bait. Then they eat the heart, see it as a premium item".

Sri Lankan fishermen often ask dolphins to find fish stream. They know that when there are dolphins in the sea, that deep can of tuna. But when not catch the tuna, they turned to catch the dolphins. Sometimes 5 boats can carry about 65 dead whales. Beruwella port has more than 200 fishing boats catch average of 3,000 dolphins every year. But how much value is there: just 12 euros a cheaper tuna and yellow 20 times to 10 times cheaper than sharks.

The massacre took place quietly, in spite of the Government of Sri Lanka signed a law established whale sanctuary and dolphins in the Indian Ocean. And since 1993, an international agreement stipulates a maximum prison term of two years for those who kill, buy or sell dolphins and whales in the waters there. But the result is almost zero.

 Because once the Sri Lankan fishermen were not well equipped to catch tuna, when no flow detector fish for dolphins tragedy will continue. Experts estimate that each year about 30,000 dolphins to be killed. The dolphin protection organizations are trying to call on the Government of Sri Lanka quickly to prevent accidents on the dolphins caught on.

Discovered 2,200-year-old mummy obesity

They are old, important enough to be embalmed, but that is not where the image to emulate you. You are overweight and obese, lazy even further? It looks but not only you like that, I'm not talking about this era, but from thousands of years ago muscles!

First. the remaining part of the remains of a 2,200 year old ancient pastors have been on display at the Israel Museum last Tuesday. CT scan showed the mummy was that this man, named Iret-hor-IRU (Eye of Horus Protection) illnesses such as arterial blockage tooth decay, the diseases commonly found in many fatty society obesity today.

Discovered 2,200-year-old mummy obesity

Exhibition curator Galit Bennett said the mummy is nicknamed Alex met many other diseases such as osteoporosis and loss benefits, the signs indicate that this person when alive were eating a lot of sugar and starch. Alex autopsy showed less activity and less in the sun, just sitting in the enjoyment of life's regal Egyptian elite.

"Osteoporosis is a disease typical in the 20th century, when people no longer have to work hard anymore. Generation onwards he began tied to the computer screen more", he Bennett pot. "We were surprised that in the past many thousands of years ago, also has the physical inactivity affects the body as this example here."

But what really is not strange, because according to the ancient sculptors, the overweight is a sign of money and health. That the food is not plentiful and the "fat" is something to pursue. In Europe, major weight shows you have a life of wealth, not hard physical labor whatsoever. It seems that the ancient Egyptians did not so much different.

But Alex is not "obese mummy" single. An experimental sessions were conducted in 2013 on the 137 mummies from around the world have shown that 34% of these mummies was cardiovascular disease. Even the study of the corpse found near Kagamil Island Alaska also showed that cardiovascular disease is not uncommon, even in those who regularly exercise.

Although many consider atherosclerotic disease is disease of modern times, but the evidence that has emerged from this disease before forming the modern world has opened up the possibility that cardiovascular disease is a nature has not been studied. Anyway, do not be inactive, and eating too much food is harmful to health, keep yourself healthy.
