AI – The Mind of the Future

June 8, 2018

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 game Go without human aid or programming. It did this simply by playing the game multiple times against itself.

AI Prints, Phone Cases, Masks, 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 super intelligence is one which is symbiotic with humanity…mark my words: AI is far more dangerous than nukes.”

Other scientists are less pessimistic, seeing AI as a step forward for technology and the world.

Mimicry in Nature

June 7, 2018

Is 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 look like their environment.

Mimicry and camouflage are two separate survival tactics.

An example of mimicry is an animal appearing to be a different animal, usually a larger and stronger one, to scare off predators. The pattern on the wings of an Owl Moth (photo above) resembles the eyes and face of an owl.

Stock Images of Mimicry in Nature

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 relative.

dead-leaf-katydid.png

Camouflage, where an animal resembles its surroundings 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.


snakes.jpg

Animal mimicry is found through the animal and even the plant world. One of the most amazing examples is the octopus, which can change not only its color but also its skin texture within seconds to hide in a variety of underwater environments.

Additionally, the mimicking species may smell, sound or act like the creature or object it is copying.

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

June 4, 2018


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. 

Stock Images & Stock Video About Alzheimer's Disease

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, everyone forgets things on occasion. However, with those suffering from Alzheimer's Disease, memory loss and confusion become more frequent, eventually interfering with daily living. They will also exhibit bouts of unexplained anger, depression and mood swings. Usually, close family and friends are the first to notice that something is not right.

In the long run, a patient suffering from Alzheimer's will need care 24 hours a day. They will not recognize family, will forget basic vocabulary, and not know how to feed themselves or accomplish even the most basic day-to-day tasks without assistance.

The brain of an Alzheimer's patient deteriorates due to the development of a type of plaque in brain cells called beta-amyloid, as well as tangles in nerve cells called tau. 

Treatment is limited, as there are only 5 drugs available that slow the progression of memory loss but do not stop it. Sleep drugs, anti-depressants and other mood enhancing drugs are usually prescribed to deal with common symptoms.

We have no way to cure Alzheimer's, nor to restore parts of the brain that have been lost. 

Luckily, there are many new drugs in development. Researchers are working on drugs to slow the deterioration of brain cells. Some hope to develop drugs that may one day even prevent Alzheimer's altogether. 

If pharmaceutical companies are successful, there may be a much brighter future for the elderly and the world may never reach the 82 million patients currently expected to develop this terrible disease.

Lower Back Pain? You're in Good Company

May 31, 2018

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, bones, muscles, and ligaments that must coordinate to do their work. The lower back supports your upper body and provides sensation and power for the 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. Numerous medical conditions may also contribute, such as arthritis, lumbar spinal stenosis, sciatica, osteoporosis, scoliosis or herniated discs. 

Your lower back may be perfectly healthy, but you may give yourself lower back pain through your actions. Take a fall, slouch, lift a heavy object, or carry too much weight and your back may be in pain.

Most frustrating is that lower back pain may be caused by something other than your back, called referred pain. Tumors, kidney infections, endometriosis, and fibromyalgia are likely medical culprits.

But do not fear; there are several things you can do to prevent or minimize the odds of suffering from lower back pain. Exercise and maintaining a healthy weight are at the top of the list. Don't smoke because it restricts blood flow to your spine. Practice proper posture when sitting, standing, and lifting.

If you do get lower back pain, it often clears up after a few days or weeks. To be on the safe side, always check with your doctor.

Feathered Dinosaurs

May 31, 2018

Could the giants of the Jurassic have sported feathered frills and colored plumage? Modern paleontology investigates 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 integumentary structures in the dorsal spines of reptiles and fish gave further support to the theory.

In 2016, the Museum of Natural History in New York showcased a new exhibit called Dinosaurs Among Us, which featured feathered dinosaurs beside their winged counterparts – birds.

Biometrics: Never Need a Password Again

May 25, 2018

Imagine never having to remember a password or enter a PIN number again. Your phone, computer, bank account and even your own front door will all be able to recognize you through the use of biometrics. Your fingerprints, ears, voice, face, iris, retina, gait and even your distinct odor can already be used to identify you.

As convenient as it sounds - since you will always have your body with you - some are concerned about the potential for invasion of privacy and also the possibility of security breaches.

Stock Images About Biometrics

If a hacker steals your password, you can create a new one. But, if the computer storing your biometric data is hacked you cannot get a new ear, iris or voice. And since biometric security opens many doors, literally and figuratively, hackers may be able to gain much more than with a single password.

Privacy advocates warn this may be the beginning of Big Brother watching you, and not just online. Facial recognition software can pick an individual out of a football stadium full of people. Security cameras are already prevalent in public places, making it possible for you to be followed by the police, the government,  companies and hackers. This can happen as you walk down the street, shop, bike, or do anything where security cameras are located.

You may say, "I'm not going to hand over my biometric data to anyone." Well, the truth is you may already have done so.

Touch ID on cell phones and voice-controlled assistants such as Alexa or Echo collect your fingerprints and your voice print. Social media sites such as Facebook already use facial recognition software to label photos of you and your friends. Even your iris can now be scanned from up to 30 feet away without you being aware.

Biometric Coffee Mugs, Masks, and more

In short, it looks like biometrics is here to stay as a method of identification and for use in security. One can only hope that those with the data do the best they can to keep your personal face, ear, eye, and other biometric information safe from hackers.

Plastic: A Global Crisis

May 25, 2018

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 onto the water and eventually out to sea.

“Everyone is looking for a sexy answer," Ted Siegler, a resource economist, remarks. “The reality is, we need to just collect the trash."

Hope lies ahead, as countries develop more efficient systems of recycling, but in the meantime, Mother Nature is left paying the lofty price.

Beauty From the Center of the Earth

May 14, 2018

 

"He who owns this diamond will own the world, but will also know all its misfortunes. Only God or woman can wear it with impunity." A Hindu warning claims this of the Koh-i-Noor Diamond.

The Delhi Purple sapphire is "accursed and is stained with the blood, and the dishonor of everyone who has ever owned it." It is kept in seven locked boxes which are surrounded by good luck charms.

 Stock Images of Gemstones Created by Volcanos

Gems have entranced, mystified and terrified us through the ages. You may not realize gemstones are born from magma or molten rock, originating deep inside the earth. Gemstones are mineral crystals which are cut and polished to be worn as adornments. This includes diamonds, amethysts, rubies, sapphires, emeralds, garnets, opals plus many more.

Rare and flawless stones can fetch high prices, some in the millions of dollars per carat. Currently, the most expensive gem is the Pink Star Diamond which recently sold at an auction for $71.2 million.

Magma may be as hot as 2,400 degrees fahrenheit. It rises from the mantle which is 21 miles beneath the earth's crust, and often travels through volcanic pipes. As it nears the surface it begins to cool down. If it surfaces, it's called lava and can solidify in 15 minutes. If kept trapped within the earth's crust it cools more slowly and this is where minerals, including gems, may form. Some minerals, such as emeralds, may only take a few hundred years to form, while others may take hundreds of thousands of years. A diamond takes up to 3 billion years to form.

Gemstone tote bags, masks, and other custom gifts

The exact chemical composition of the magma determines the type of mineral, plus the amount of pressure it is kept under. Diamonds are made of carbon under extreme pressure. Emeralds are a mix of beryllium, aluminum, silicon, and oxygen.

Considering how long they take to develop it is understandable that humans place such a high monetary value on gemstones. Along with the carat size, purity, rarity, color, clarity, and even the history of a stone contribute. Gemstones also hold value to geologists and gemologists who can learn about the geology of an area based on the types of gemstones found there. 

And unlike a cut flower that wilts quickly, the beauty of a gemstone may last as long as it took to be created.

Volcanic Eruptions: Kilauea and Beyond

May 12, 2018

A wall of lava flows down Hoʻokāpu Street on Hawaii's Big Island, engulfing cars and setting trees ablaze – one of many scenes of havoc following the eruption of Kilauea in May.

Deriving their name from the Roman god of fire, Vulcan, volcanoes live up to their reputation as one of nature's most fearsome phenomena. Literally openings in the earth's surface, and volcanoes exist throughout the world, including underwater. 

Stock Images & Stock Video of Kilauea and Other Volcanos

Volcanoes usually occur where tectonic plates separate but they can also arise from hot spots in the earth's crust, such as in the Hawaiian Islands and Yellowstone National Park. When pressure builds up and travels to the earth's surface, an eruption occurs that can last between one hour and hundreds of years. The Island of Stromboli's volcano has been continuously active for over 2,000 years.

In addition to lava, ash and fire, eruptions are often accompanied by earthquakes, mudslides, and acid rain, causing massive damage to the surrounding environment. The 1980 eruption of Mount St. Helens destroyed 200 houses, 15 miles of highway and 4 billion board feet of timber.

Volcanic eruptions are not solely destructive, however. The lava they produce can clear away brush and treat the soil, making the land highly fertile for new plants and agriculture.

Life on Other Planets

May 11, 2018

For centuries people have mused about life in outer space. Novelists have explored space colonies on other planets, while tabloids have made millions on UFO sightings and abductions. Despite the demand, scientists have yet to find our neighbors in the vast backyard of outer space. 

Explore Stock Images of Life on Other Planets

Physicists identify areas of space capable of sustaining life as circumstellar habitable zones (CHZ), or Goldilocks zones. For a Goldilocks zone to exist it must have temperatures that allow for liquid water. Scientists believe that about 40 percent of red dwarf stars have Goldilocks zones, making the likelihood of extraterrestrial life extremely high. There are scientists, however, who believe other requirements exist, such as geological conditions involving surface water, as well as biochemical factors.

It's possible that lifeforms could exist in areas of space uninhabitable to human beings. Tardigrades, or water bears, are known to withstand harsh physical conditions, such as high pressure levels and extreme temperatures above and below freezing. Some scientists have suggested that creatures like water bears might live in the oceans of other planets and moons and that one such ocean might lie beneath the icy shell of Jupiter's moon, Europa.

Invincible Water Bears

May 11, 2018

Although they can survive unprotected in outer space, these resilient creatures are terrestrial living beings, not aliens as some have claimed. They are found on every continent on planet Earth and they love the water, yet can be found in the desert as well.

First discovered by pastor and zoologist Johann Goeze in 1773 and later named Tardigrada (Italian for "slow stepper"), these creatures still fascinate scientists today.

Stock Images & Stock Video of Tardigrades

It's unlikely that Goeze knew how amazing tardigrades (also called water bears) really are. They can withstand a high temperature of 300 degrees and a low of -458 degrees F. They have also survived outer space, radiation, and six times the pressure of the deep sea.

How do they do this? When faced with adverse conditions they can desiccate - dry up - themselves. When in this state they are referred to as 'tuns' and resemble a little ball. It is a death-like state called cryptobiosis. Water bears usually only live a few weeks or months but can be revived from a state of cryptobiosis after 30 years.

Water bears need at least a small film of water to be in their normal mobile state. They suck water from the moss and plant matter they usually live in. They prefer living in the moist sediment in the bottom of lakes but have been found in arid regions as well. As long as there is just a little water, they can thrive.

Cute Water Bear Throw Pillows

Even though human beings might not survive a catastrophe such as a supernova or asteroids, it seems that water bears will be around many millennia after we are gone.

Hepatitis C and The Miracle of Modern Medicine

May 10, 2018

Only a few years ago hepatitis C was a dreaded incurable disease whose victims led long-suffering lives until they died. They often succumbed to liver failure, cirrhosis, liver cancer (hepatocellular carcinoma) and were in the need of a liver transplant. Successful drug trials were run in 2013 and today there are several drug cures on the market.

In the past, the drugs one needed to stay alive had unpleasant side effects that made daily life miserable. Now a common cure takes as little as 8 - 12 weeks and is successful in 90% - 100% of cases.

Stock Images About Hepatitis C

These new drugs are direct-acting antivirals, called DDAs. They target hepatitis C, which is spread through blood to blood contact. A number of DDAs have been approved by the FDA and a few of them fight all six genotypes of hepatitis C which simplifies treatment.

A person with hepatitis C will have few symptoms at first, but if untreated, may develop swollen legs and abdomen, internal bleeding, gallstones, enlarged spleen, type 2 diabetes, kidney failure and lung failure. They may also struggle to fight off infections with a compromised immune system.

Hepatitis Mugs to Help You Visualize

Hepatitis C is contracted through blood to blood contact. Today up to 80% of hepatitis C infections will be caused by the sharing of hypodermic needles. Before 1990, hepatitis C was mostly transferred via a blood transfusion. As of 1990, a screening test for blood went into effect.

Less common ways to contract the infection is to work around blood or needles. Doctors, nurses and laboratory workers must exercise caution. Improperly cleaned medical equipment can also cause contractions in patients such as those receiving dialysis.

Additionally, individuals with a risky sex life may also get infected. Those who get body piercings, tattoos or even a manicure or pedicure should ensure that tools are sterile.

As usual, the downside of any miracle in modern medicine is the cost. Since there are a variety of cure regimens, some may cost almost $100,000. Yet, many people are willing to pay any amount to regain their quality of life or even just to remain alive.

Ticks, Mosquitos and Fleas. Oh My.

May 3, 2018

Nice weather has arrived at last, but based on a recent CDC (Center for Disease Control and Prevention) report, you should take precautions before you head to the great outdoors. If not, you could end up with serious health concerns after a leisurely stroll in the woods.

Vector-borne diseases, those transmitted through bites from ticks, mosquitos and fleas, have more than tripled in recent years. Nine new diseases have been discovered or introduced to the Americas.

Along with Lyme, Rocky Mountain Spotted Fever, Anaplasmosis, the Plague and other ills, we now need to protect ourselves from Zika virus, the Heartland and Bourbon viruses, Borrelia miyamotoi and Borrelia mayonii bacteria, Rickettsia parkeri, Rickettsia 364D, Ehrlichia species and chikungunya.

More Stock Images About Vector-Borne Disease

Once infected, a person may need weeks, months or even years to recover. In some cases, people never recover. In certain cases they are fatal.

The best way to protect yourself is to wear long sleeves, long pants, socks, closed toe shoes, and hats. It's recommended that shoes and clothes be sprayed or embedded with the insect repellent permethrin. Any exposed skin should be sprayed with an approved insect repellent such as DEET.

A few factors that contribute to the increase in these diseases are jet travel, warmer temperatures, reforestation of land and a lack of vaccines.

Images of Viruses, Insects and other
Creepy Things on Notebooks

In the past, when travel to other countries was done by sailing ship, vector-borne diseases took longer to be transferred. With jet travel, people may begin their journey before they even know they have been infected. Once in a new country a tick, mosquito or flea may bite them rapidly, spreading an infection to new locations.

As suburban housing spreads into forested areas, more and more people are living in tick-friendly environments. More deer, mice and other mammals who can transport ticks live in closer proximity to people than ever before as their natural environments dwindle.

Areas that were once uninhabited, or minimally inhabited, such as farmland, are being converted to forested suburbia as the human population increases.

Climate change may or may not contribute. Warmer winters mean more pests, but only up to a point. Once areas become too hot or dry, mosquitos, for example, can't thrive. 

In short, the factors are very complicated, and not all scientists agree on exactly why there has been an increase. But everyone does agree that it's wise to take precautions when going outside, and to see your doctor as soon as possible if you think you may have been infected.

Deep Sea Exploration

April 26, 2018

 

The world can feel like a small, crowded place, but actually two-thirds of the planet remains relatively unexplored. Over 1,500 people have climbed Mount Everest, but only THREE have gone to the deepest part of the ocean.

Up until recently, we haven't had the technology to fully study and explore the oceans, but the race is on. Why is this so urgent? Over 70% of the oxygen we breathe comes from marine life such as plankton. Due to increased CO2 (carbon dioxide), pollution and other manmade changes to the environment, plankton may end up on our endangered species list one day.

Stock Images of Undersea Exploration and Creatures

To protect plankton, marine life and the oceans overall, we first need to understand what is normal, how things are changing, how fast and why. We know that the oceans dissolve much of the excess CO2 that humans create. But this makes oceans more acidic, damaging and killing coral and plankton, and adversely affecting much other marine life.

The biggest challenge in deep-sea exploration has always been the increased pressure the deeper one goes. Most divers comfortably go no further than 130 feet before succumbing to the eventually fatal pressure. The deepest part of the ocean, an area called Challenger Deep near Guam, is about 36,200 feet deep.

Scary Ocean Creature Coffee Mugs

The first submarine was built in 1620 by Dutch inventor Cornelius Drebbel. It traveled along the banks of the Thames River in London, diving to a depth of 15 feet. In 2012, filmmaker James Cameron descended to a depth of 35,787 feet in the DSV Deepsea Challenger, a deep-diving submersible. He was only able to stay at the bottom for about an hour before having to resurface. 

The only other two people to dive deeper were Jaques Piccard and Don Walsh in the Swiss & Italian Bathyscaphe Trieste. They reached 35,797 feet in the Challenger Deep section of the Mariana Trench in 1960. 

New unmanned robots called mini autonomous underwater vehicles are being used more often. Many of them can be released at once and send back data over a period of time. They could only stay 20 minutes, as one of the windows began cracking from the pressure.

One of the most fascinating and surprising things scientists are discovering is the prevalence of biofluorescent creatures. Even tetrapods, such as sea turtles have been found to glow in the dark of the ocean. Unlike bioluminescent creatures, which make their own light through a chemical reaction, biofluorescent creatures glow when certain wavelengths of light shine on them.

Scientists have discovered over 250 species of fish that use biofluorescence and believe this may be a method of communication in the deep ocean.

As we learn more about the oceans, we can hopefully learn how to save them and also ourselves from extinction.
