AI - The Mind of the Future

AI, technological leap or existential threat? From robotic telephone calls to self-driving cars, everywhere you look Artificial Intelligence is entering into our lives. While it might unnerve some, much of this technology falls under the category of weak or narrow AI, meaning it's designed to learn and perform a single task. Specialists are more concerned with strong AI that can adapt to different situations, acquiring new skills and knowledge. Last October, Google released a unit called Alpha Go Zero, which was able to learn the Chinese video gameGowithout human aid or programming. It did this simply by playing the game multiple times against itself.AI Prints, Phone Cases and More The full potential of strong AI is still unknown, making it a cause for concern for many. In a recent interview, the preeminent scientist and entrepreneur Elon Musk said: “We have to figure out some way to ensure that the advent of digital superintelligence is one which is symbiotic with humanity…mark …

Animal Mimicry and Camouflage

s it a twig or an insect? A harmless moth or a scary owl? Animals have amazing tricks up their sleeves to protect themselves, take advantage of looking like another creature or looking like their environment. There are many types of animal mimicry. One example is an animal that pretends to be a totally different animal, usually much larger and stronger one, to scare off predators. The pattern on the wings of an Owl Moth (photo above) resemble the eyes and face of an owl. Stock Images of Mimicry in Nature Camouflage, where an animal resembles it's surrounding to hide from predators, is a much-studied type of mimicry. The Dead Leaf Katydid is a beautiful example. It looks just like the dead leaves it lives on. Other animals look like rocks, thorns, twigs, flowers and even bird droppings. The King Snake, which is non-poisonous, has a scale pattern like that of the Coral Snake, a type of venomous snake. It tricks predators into thinking they have encountered its very dangerous relati…

Feathered DInosaurs

Could the giants of the Jurassic have sported feathered frills and colored plumage? Recent scientific evidence may prove this wild theory. The evolutionary connection between birds and dinosaurs has been a fierce debate among scientists for generations. Thomas Huxley first suggested the species shared a common ancestry in 1856 when he compared the fossils of Compsognathus and the first bird, Archaeopteryx lithographica. In 1876, he created a feathered model of Compsognathus and presented it at a lecture in New York City. But the preeminent dinosaur expert, Richards Owen, rejected the theory, and it laid dormant for decades.
Stock Image Gallery It was not until 1969 that John Ostrom revived the subject. His work drew new parallels between birds and dinosaurs, such as similarities in their necks, pelvises, and wrists. Quill knobs (feather access points) under the forearms of some dinosaurs as well as integumentary structures in the dorsal spines of reptiles and fish gave further support…

Lower Back Pain? You're in Good Company

If you have lower back pain, you are in good company. According to researchers, more than 80% of all Americans will suffer from lower back pain at some point in their life. One of the reasons it is so widespread is that this pain can be caused by many conditions, some not even related to your back. The back is a complex framework of joints, bone, muscles, and ligaments, that must coordinate to do their work. The lower back supports your upper body and provides sensation and power for movement of hips, legs, and feet. Your back also houses and protects your spinal cord.Stock Images & Video About Lower Back Pain This complexity makes your back susceptible to injury and disease if not properly cared for. Muscles can be pulled, sprained, become inflamed or even torn. Bones can fracture or break. The nerves protected inside your spine may swell or get pinched. There are numerous medical conditions that may contribute as well, such as arthritis, lumbar spinal stenosis, sciatica, osteop…

Alzheimer's Disease, a Tragic Future for Our Aging Population

An estimated 82 million people will have dementia by 2030, according to the World Health Organization. By 2050, the number of people with dementia in the U.S. will be double what it is today, and 80% of these individuals will have Alzheimer's Disease. Alzheimer's is a noncurable condition that causes problems with memory, thinking and behavior. A person can have the beginnings of Alzheimer's for years without any visible symptoms. It progressively worsens over time and never improves. Most people develop Alzheimer's after age 65, although some people may get Early-Onset Alzheimer's decades earlier.  The greatest factors in getting Alzheimer's is aging and having Alzheimer's in your family. High blood pressure, high cholesterol, and diabetes also increase the odds. Head injuries and not sleeping regularly contribute to a lesser degree as well.

At first, symptoms may not be very noticeable. Misplaced keys, a lost book, a missed appointment. After all, everyon…
While plastic has given much to modern society, like inexpensive products and durable packaging, it's also had disastrous consequences. A recent study from Georgia University found that 18 billion pounds of plastic are dropped into the ocean each year. This has resulted in massive islands of waste forming at sea that destroy aquatic life and poison the water. One such island in the Pacific now equals the size of Texas.Stock Images of Our Polluted Oceans The chemicals in plastic often enter into fish's stomachs, making them potentially harmful to the animals that eat them, including people. "I don’t think we should be waiting for a key finding of whether or not fish are hazardous to eat,” says biologist Richard Thompson. “We have enough evidence to act.” Georgia University reports that only a fifth of all plastic is ever recycled. The problem lies mostly in developing nations but extends globally. Major cities often create landfills by waterways where plastic blows out on…

Teacher Appreciation

Dot those i's, cross those t's, tighten up that bibliography and pipe down in the back row because this is Teacher Appreciation Week! Though you might envy their free summers and holidays off, teachers have a uniquely challenging year. According to a study by the NEA, teachers work an average of 50 hours a week and earn less money than most professionals with equivalent degrees.

On average, teachers pay $500 a year out of pocket for classroom supplies. And 65 percent of teachers also cover the cost of lunches and field trips for their kids.
While being a teacher is not the easiest or most lucrative profession, the rewards lie elsewhere. One poll revealed that 88% of people surveyed said a teacher had a positive impact on their life.Gifts for the Teach
