8 new planets found in ‘Goldilocks zone’


Astronomers with the Harvard-Smithsonian Center for Astrophysics (CfA) have discovered eight new planets within the so-called Goldilocks — or habitable — zone of their stars.

This artist's rendering provided by NASA on April 17, 2014 shows an Earth-sized planet dubbed Kepler-186f orbiting a star 500 light years from Earth.

To be considered habitable, exoplanets must orbit within a distance of their stars in which liquid water can exist on the planet’s surface, receiving about as much sunlight as Earth.

“Most of these planets have a good chance of being rocky, like Earth,” lead author Guillermo Torres of the CfA said in a release.

The discoveries of Kepler-438b and Kepler-442b are the latest in several advancements scientists have made to find signs of possible life in the universe.

At a panel held last summer at NASA headquarters in Washington, astronomers said they were “very close in terms of technology and science to actually finding the other Earth.”

That’s due in part to the Kepler Space Telescope. The planet-hunting Kepler probe, launched in 2009, finds planets by looking for dips in the brightness of a star as a planet transits, or crosses, in front of that star.

Christine Pulliam of CfA said the team of scientists monitored data from more than 160,000 stars, which led them to the eight new planets.

The couple most like Earth, Kepler-438b and Kepler-442b, both orbit red dwarf stars, which are cooler and smaller than the Earth’s sun.

Kepler—438b’s diameter is 12 per cent bigger than Earth and has a 70 per cent chance of being rocky, which means the surface of the planet appears to be like Earth’s.

Kepler—442b is about one-third larger than Earth with a 60 per cent chance of being rocky. Scientists give it a 97 per cent chance of being in the habitable zone, but caution that the estimations aren’t certain.

“We don’t know for sure whether any of the planets in our sample are truly habitable,” second author David Kipping of the CfA said in a release.

“All we can say is that they’re promising candidates.”

 

 

Scientists Officially Link Processed Foods To Autoimmune Disease


The modern diet of processed foods, takeaways and microwave meals could be to blame for a sharp increase in autoimmune diseases such as multiple sclerosis, including alopecia, asthma and eczema. A team of scientists from Yale University in the U.S and the University of Erlangen-Nuremberg, in Germany, say junk food diets could be partly to blame. ‘This study is the first to indicate that excess refined and processed salt may be one of the environmental factors driving the increased incidence of autoimmune diseases,’ they said. Junk foods at fast food restaurants as well as processed foods at grocery retailers represent the largest sources of sodium intake from refined salts. The Canadian Medical Association Journal sent out an international team of researchers to compare the salt content of 2,124 items from fast food establishments such as Burger King, Domino’s Pizza, Kentucky Fried Chicken, McDonald’s, Pizza Hut and Subway. They found that the average salt content varied between companies and between the same products sold in different countries. U.S. fast foods are often more than twice as salt-laden as those of other countries. While government-led public health campaigns and legislation efforts have reduced refined salt levels in many countries, the U.S. government has been reluctant to press the issue. That’s left fast-food companies free to go salt crazy, says Norm Campbell, M.D., one of the study authors and a blood-pressure specialist at the University of Calgary. Many low-fat foods rely on salt–and lots of it–for their flavor. One packet of KFC’s Marzetti Light Italian Dressing might only have 15 calories and 0.5 grams fat, but it also has 510 mg sodium–about 1.5 times as much as one Original Recipe chicken drumstick. (Feel like you’re having too much of a good thing? You probably are. Bread is the No. 1 source of refined salt consumption in the American diet, according to the Centers for Disease Control and Prevention. Just one 6-inch Roasted Garlic loaf from Subway–just the bread, no meat, no cheeses, no nothing–has 1,260 mg sodium, about as much as 14 strips of bacon. How Refined Salt Causes Autoimmune Disease The team from Yale University studied the role of T helper cells in the body. These activate and ‘help’ other cells to fight dangerous pathogens such as bacteria or viruses and battle infections. Previous research suggests that a subset of these cells – known as Th17 cells – also play an important role in the development of autoimmune diseases. In the latest study, scientists discovered that exposing these cells in a lab to a table salt solution made them act more ‘aggressively.’ They found that mice fed a diet high in refined salts saw a dramatic increase in the number of Th17 cells in their nervous systems that promoted inflammation. They were also more likely to develop a severe form of a disease associated with multiple sclerosis in humans. The scientists then conducted a closer examination of these effects at a molecular level. Laboratory tests revealed that salt exposure increased the levels of cytokines released by Th17 cells 10 times more than usual. Cytokines are proteins used to pass messages between cells. Study co-author Ralf Linker, from the University of Erlangen-Nuremberg, said: ‘These findings are an important contribution to the understanding of multiple sclerosis and may offer new targets for a better treatment of the disease, for which at present there is no cure.’ It develops when the immune system mistakes the myelin that surrounds the nerve fibres in the brain and spinal cord for a foreign body. It strips the myelin off the nerves fibres, which disrupts messages passed between the brain and body causing problems with speech, vision and balance. Another of the study’s authors, Professor David Hafler, from Yale University, said that nature had clearly not intended for the immune system to attack its host body, so he expected that an external factor was playing a part. He said: ‘These are not diseases of bad genes alone or diseases caused by the environment, but diseases of a bad interaction between genes and the environment.’ Humans were genetically selected for conditions in sub-Saharan Africa, where there was no salt. It’s one of the reasons that having a particular gene may make African Americans much more sensitive to salt. ‘Today, Western diets all have high salt content and that has led to increase in hypertension and perhaps autoimmune disease as well.’ The team next plan to study the role that Th17 cells play in autoimmune conditions that affect the skin. ‘It would be interesting to find out if patients with psoriasis can alleviate their symptoms by reducing their salt intake,’ they said. ‘However, the development of autoimmune diseases is a very complex process which depends on many genetic and environmental factors.’ Stick to Good Salts Refined, processed and bleached salts are the problem. Salt is critical to our health and is the most readily available nonmetallic mineral in the world. Our bodies are not designed to processed refined sodium chloride since it has no nutritional value. However, when a salt is filled with dozens of minerals such as in rose-coloured crystals of Himalayan rock salt or the grey texture of Celtic salt, our bodies benefit tremendously for their incorporation into our diet. “These mineral salts are identical to the elements of which our bodies have been built and were originally found in the primal ocean from where life originated,” argues Dr Barbara Hendel, researcher and co-author of Water & Salt, The Essence of Life. “We have salty tears and salty perspiration. The chemical and mineral composition of our blood and body fluids are similar to sea water. From the beginning of life, as unborn babies, we are encased in a sack of salty fluid.” “In water, salt dissolves into mineral ions,” explains Dr Hendel. “These conduct electrical nerve impulses that drive muscle movement and thought processes. Just the simple act of drinking a glass of water requires millions of instructions that come from mineral ions. They’re also needed to balance PH levels in the body.” Mineral salts, she says, are healthy because they give your body the variety of mineral ions needed to balance its functions, remain healthy and heal. These healing properties have long been recognised in central Europe. At Wieliczka in Poland, a hospital has been carved in a salt mountain. Asthmatics and patients with lung disease and allergies find that breathing air in the saline underground chambers helps improve symptoms in 90 per cent of cases. Dr Hendel believes too few minerals, rather than too much salt, may be to blame for health problems. It’s a view that is echoed by other academics such as David McCarron, of Oregon Health Sciences University in the US. He says salt has always been part of the human diet, but what has changed is the mineral content of our food. Instead of eating food high in minerals, such as nuts, fruit and vegetables, people are filling themselves up with “mineral empty” processed food and fizzy drinks.

Food for thought.


Antioxidants

Who may need more?

  • Everyone who breathes (seriously!)
  • Frequent, strenuous exercisers need even more

What do they do? Antioxidants delay cognitive decline by neutralizing free radicals, byproducts of our oxygen-guzzling metabolism that damage cells by causing inflammation. People who exercise a lot tend to eat more and breathe more heavily, which results in more free radicals. Flavonoids, one type of antioxidant, improve blood flow to the brain and enhance its ability to form memories, especially in conjunction with exercise.

Foods that have them: Colorful vegetables and fruits, red wine, cocoa, calf and beef liver

Caffeine

Who may need more?

  • Men
  • People at risk for Parkinson’s disease
  • Women in the first five days of their period

What does it do? Caffeine seems to protect the brain, although scientists are not sure exactly how. A dose of five cups of coffee per day has been shown to dramatically reduce early Parkinson’s symptoms in many people (although once the disease has taken hold, it can make tremors worse). Dark chocolate, which contains caffeine and the mood-boosting neurotransmitter anandamide, also increases beneficial estrogen levels in men, post-menopausal women and women who are in the first few days of menstruation.

Foods that have it: Coffee, many kinds of tea, cocoa, many sodas, dark chocolate

Omega-3 fatty acids

Who may need more?

  • People who are taking antidepressants

What do they do? Omega-3s are anti-inflammatory and an important component of brain cell membranes. A deficiency has been linked to brain disorders such as depression. Correcting a deficiency can boost the brain’s plasticity, enhancing cognition and learning.

Foods that have them: Salmon, tuna and other fatty fish, plants such as flaxseed, walnuts and other nuts

B vitamins

Who may need more?

  • Women and children, particularly girls
  • People who consume a lot of alcohol

What do they do? The brain needs folate (or folic acid) to keep the enzymes related to energy metabolism humming along. If a woman is deficient, additional folate may improve memory and ease depression. Studies indicate it may also help protect the brain from dementia.

Foods that have them: Fatty fish, mushrooms, fortified products, milk, soy milk, cereal grains, orange juice, spinach, yeast

Curcumin

Who may need more?

  • Young people. Studies are ongoing, but early data indicates that the sooner it is added to a diet, the better.

What does it do? The anti-inflammatory properties of curcumin, which is found in the spice turmeric, seem to protect the brain against Alzheimer’s and possibly Parkinson’s disease. Turmeric has been used in Asian herbal remedies for centuries to treat inflammatory diseases such as arthritis. (Bonus: Curcumin is also a powerful antioxidant.)

Foods that have it: Curry and some mustards contain it, and turmeric can be added to many foods.

Tryptophan

Who may need more?

  • Novice vegetarians

What does it do? The brain uses this amino acid to make seratonin, an essential mood-regulating neurotransmitter. The brain can’t store tryptophan, so you need to get a regular supply from protein in your diet. Novice vegetarians who skimp on protein often lack it and within a week can suffer symptoms such as anxiety, irritability and depression.

Foods that have it: Eggs, nuts, spinach, dairy, red meat, fish, poultry (although contrary to popular myth, turkey doesn’t contain all that much)

How can I improve my sperm quality?


Sperm quality has been in decline for many years and scientists have citied smoking, alcohol and various other habits as the reason. However the most recent research in the field by researchers at the Universities of Manchester and Sheffield found that smoking cannabis can have a severe effect on male fertility. Other lifestyle choices such as drinking alcohol and wearing tight briefs were not considered to cause any problems, despite earlier reports that suggested these as the main causes.

1.       Consume Red-coloured food: A report published by Ohio’s Cleveland Clinic, found that consumption of lycopene improved the quality, mobility and volume of sperm dramatically, increasing sperm count by up to 70 per cent. Lycopene is found commonly in red fruits and vegetables such as tomatoes,strawberries, cherries and peppers.

2.      Massage with Herbal oils: Along with regular exercise, massage improves overall blood flow and circulation. Increased circulation means healthier sperm.

3.      Stay away from the Laptop: A 2011 study published in the journal of Fertility and Sterility suggested that there could be a link between using a laptop with a Wi-Fi connection and a reduction in sperm quality. The sperm stored under the laptop became more sluggish and showed signs of DNA damage. (http://www.fertstert.org/article/S0015-0282(11)02678-1/abstract)

4.      Reduce Stress: Stress hormones block Leydig cells, which are tasked with regulating testosterone production. When your body experiences too much stress, it can actually stop producing sperm altogether.

5.      Avoid Cycling: A 2009 spanish study by the Andalusian Center of Sports Medicine and the University of Las Palmas found that a prolonged drive on your bike can severely affect the shape and quality of your spermatozoids. After monitoring 15 Spanish triathletes with an average age of 33 the study found that “those that systematically cycled 300 kilometers a week– had less than 4pc, which is considered a fertility problem”. (http://www.uco.es/uconews/article/cycling-at-a-professional-level-affects-the-quality-of-sperm/) 

6.      Eat Healthy Foods: Eat plenty of fish, meat, eggs, fruits and vegetables. Nuts like peanuts, walnuts, cashews, sunflower and pumpkin seeds are also considered to increase sperm count.

7.      Avoid Soy and High fructose corn-syrup: Soy foods have a mild estrogenic effect on the body and high-fructose corn syrup causes insulin resistance, which lowers fertility. Men who drink a quart of Cokeregularly have 30% less sperm than men who don’t drink Coke.

8.     Avoid Heat: The optimum temperature for sperm production is 34.5 degrees Celsius, which is slightly below body temperature. A three-year University of California study in 2007 found that five out of 11 men who stopped taking hot baths experienced a sperm count rise of almost 500 per cent. (http://news.bbc.co.uk/2/hi/health/6418771.stm) 

9. Consume Supplements:  Try supplements that are made from natural herbal ingredients to specifically help the body make more semen. Research found that men who consumed 5 mg of folic acid and 66 mg of zinc sulfate a day for 26 weeks experienced an almost 75 percent increase in sperm count. Vitamin C and selenium may also be good supplements to take in order to increase sperm production.

10 . Eat Brassica Vegetables: Vegetables such as broccoli, brussels sprouts and cabbage cleanse the liver. They help the liver detoxify, and lowering your toxic load improves sperm health.

11.   Drink Coffee: In 2003, researches from Sao Paolo University in Brazil studied 750 men and concluded that drinking coffee can improve the swimming speed of human sperm, although whether this means pregnancy rates are higher among coffee drinkers is unclear. Some other studies have suggested that drinking just three cups of coffee a day can cause genetic mutations in sperm, making it harder for them to successfully fertilise an egg.

Why Black Widow Spider Venom Is So Potent


The painful bites and lethal venom of black widow spiders have evolved rapidly over the years, according to a new study that also found common house spiders produce similar toxic compounds.

The difference is that female black widows produce ample amounts of highly potent venom to the point that these spiders are even crafting stronger webs to handle ever-bigger prey. The findings were presented at the 2015 annual conference of the Society of Integrative and Comparative Biology in West Palm Beach, Fla.

The most powerful neurotoxins present in black widow venom are called latrotoxins, which take their name from the group of widow spiders known as Latrodectus. The most toxic of these latrotoxins is alpha-latrotoxin that hijacks the poor victim’s own nervous system.

“If you got bitten by a black widow, alpha-latrotoxin would travel to the pre-synaptic regions of your neurons: this is the juncture right between the synapse of one neuron and your muscle cells or another neuron, and it inserts itself into the membrane,” explained Jessica Garb of the University of Massachusetts, Lowell, in a press release.

She added, “This causes all of the neuron’s vesicles to dump out their neurotransmitters. And that’s really what’s painful.”

Garb and her colleagues determined that latrotoxins are more common in the world of arachnids than previously thought. Many spiders produce the toxins to help with their own hunting, but they make such a watered down version that they’re not harmful to most people.

Female black widows, on the other hand, have quickly evolved super concentrated venom that can kill a person. Each year, about 2,200 people report being bitten by a black widow, but most recover within 24 hours with medical treatment.

Many people who are bitten develop few symptoms since the spider may not inject its venom. Black widows are actually not very aggressive spiders, so you really have to startle or otherwise threaten one to get a hostile reaction.

As for why black widows, in particular, have evolved such potent venom, Garb and her team think it was to expand the spider’s diet. Black widows can consume small mammals and reptiles, in addition to more typical smaller prey. As their name suggests, females may also kill their mates, so it seems they are not averse to eating most things.

The researchers also discovered that black widow spider venom contains a cocktail of other toxins that boosts the effectiveness of alpha-latrotoxin.

Understanding spider venom could lead to better treatments for bites. Some scientists also believe that the venom holds untapped medical benefits. Research is ongoing, for example, on how latrotoxins and related compounds might hold the keys to treating Alzheimer’s, cancer, pain, and even sexual problems.

 

The Science Of ‘Breaking The Seal’: Urge To Urinate Comes More Often With Inhibition Of Anti-Diuretic Hormone


Once you go that first time, you’ll be going all night. “You’re going to ‘break the seal,'” your buddy shouts after you as the bathroom door hits you in the back. Alcohol’s effect on the antidiuretic hormone (ADH), also known as arginine vasopressin, is to blame for bar bathroom lines or dreaded tailgating port-o-potty visits.

Bathroom Breaks Caused By Alcohol

The cycle starts and ends with ADH, which is produced in the hypothalamus — the part of the brain that controls a number of bodily functions, including hunger, thirst, sleep cycle, and body temperature. The hormone is stored and released from the pituitary gland, where it controls the amount of water released from the kidneys into the urine. It retains a healthy amount of water by creating a permeable area in the kidneys, which helps to keep water flowing back into the bloodstream instead of out through the urine.

High levels of ADH cause the kidneys to retain water inside the body, which ultimately makes you have to go to the bathroom much less. Thirst, nausea, vomiting, pain, and sleep all cause an increase in the hormone in an effort to retain water. It’s the reason why an otherwise healthy person won’t pee their bed as they sleep, according to the Society for Endocrinology.

Alcohol, on the other hand, prevents the ADH from releasing, which is what causes an increase in urine production and dehydration. It’s like removing the dam in your kidneys and causing water to free more quickly into your urine. You keep running to the bathroom, but because your body doesn’t have ADH to retain water, you’re also really thirsty so you drink more alcohol — and the cyclical mayhem continues all night long.

“[Alcohol] decreases your ADH and you are producing more fluid. So when you produce more fluid and you fill your bladder more, you suppress more ADH,” Urologist Dr. Courtenay Moore, from the Glickman Urological and Kidney Institute at Cleveland Clinic, said in an interview with NBC News. The bladder will become irritated and can lead to an uncomfortable feeling often mistaken for having a full bladder, despite itself.

You’ve Broken The Seal

It only takes a small amount of alcohol to block ADH, and as you continue to drink, your ADH levels continue to drop while urine production increases. By your third or fourth drink, it’s more than likely your body is screaming at you to run to the bathroom and release. By the time you make that first initial pee, your ADH is even more suppressed because the alcohol continues to block its ability to retain water in the body. Your kidneys are engaged and working smoothly, which is why you’ll need to go more often.

If you’re drinking beer, champagne, jack and coke, or anything with soda, the carbonation will make the urges to pee stronger. The carbonation of drinks can cause gas and pressure, which when combined with a full bladder and no brakes (ADH), your bladder will feel fuller than it is in reality. It’s not a myth or some psychological mumbo-jumbo — your body is going through these physiological changes with each sip of your Sunday mimosas or Tuesday twofer special.  Run to the bathroom all you want, there’s no stopping it.

Eight new planets found in ‘Goldilocks’ zone: Two are most similar to Earth of any known exoplanets — ScienceDaily


Astronomers announced today that they have found eight new planets in the ‘Goldilocks’ zone of their stars, orbiting at a distance where liquid water can exist on the planet’s surface. This doubles the number of small planets (less than twice the diameter of Earth) believed to be in the habitable zone of their parent stars. Among these eight, the team identified two that are the most similar to Earth of any known exoplanets to date.

This artist’s conception depicts an Earth-like planet orbiting an evolved star that has formed a stunning “planetary nebula.” Earlier in its life, this planet may have been like one of the eight newly discovered worlds orbiting in the habitable zones of their stars.

Among these eight, the team identified two that are the most similar to Earth of any known exoplanets to date.

“Most of these planets have a good chance of being rocky, like Earth,” says lead author Guillermo Torres of the Harvard-Smithsonian Center for Astrophysics (CfA).

These findings were announced today at a meeting of the American Astronomical Society.

The two most Earth-like planets of the group are Kepler-438b and Kepler-442b. Both orbit red dwarf stars that are smaller and cooler than our Sun. Kepler-438b circles its star every 35 days, while Kepler-442b completes one orbit every 112 days.

With a diameter just 12 percent bigger than Earth, Kepler-438b has a 70-percent chance of being rocky, according to the team’s calculations. Kepler-442b is about one-third larger than Earth, but still has a 60-percent chance of being rocky.

To be in the habitable zone, an exoplanet must receive about as much sunlight as Earth. Too much, and any water would boil away as steam. Too little, and water will freeze solid.

“For our calculations we chose to adopt the broadest possible limits that can plausibly lead to suitable conditions for life,” says Torres.

Kepler-438b receives about 40 percent more light than Earth. (In comparison, Venus gets twice as much solar radiation as Earth.) As a result, the team calculates it has a 70 percent likelihood of being in the habitable zone of its star.

Kepler-442b get about two-thirds as much light as Earth. The scientists give it a 97 percent chance of being in the habitable zone.

“We don’t know for sure whether any of the planets in our sample are truly habitable,” explains second author David Kipping of the CfA. “All we can say is that they’re promising candidates.”

Prior to this, the two most Earth-like planets known were Kepler-186f, which is 1.1 times the size of Earth and receives 32 percent as much light, and Kepler-62f, which is 1.4 times the size of Earth and gets 41 percent as much light.

The team studied planetary candidates first identified by NASA’s Kepler mission. All of the planets were too small to confirm by measuring their masses. Instead, the team validated them by using a computer program called BLENDER to determine that they are statistically likely to be planets. BLENDER was developed by Torres and colleague Francois Fressin, and runs on the Pleaides supercomputer at NASA Ames. This is the same method that has been used previously to validate some of Kepler’s most iconic finds, including the first two Earth-size planets around a Sun-like star and the first exoplanet smaller than Mercury.

After the BLENDER analysis, the team spent another year gathering follow-up observations in the form of high-resolution spectroscopy, adaptive optics imaging, and speckle interferometry to thoroughly characterize the systems.

Those follow-up observations also revealed that four of the newly validated planets are in multiple-star systems. However, the companion stars are distant and don’t significantly influence the planets.

As with many Kepler discoveries, the newly found planets are distant enough to make additional observations challenging. Kepler-438b is located 470 light-years from Earth while the more distant Kepler-442b is 1,100 light-years away.

Quantum dot televisions are coming to a living room near you – ScienceAlert


Electronics manufacturer LG has shown off its new quantum dot television at a trade show in the US, and it’s expected to be available in 2016.

A new quantum dot television has been shown at the Consumer Electronics Show (CES), the world’s largest consumer electronics and technology exhibition for technology that will become available in the next 12 months.

At the event, Korean electronics and display manufacturer LG announced its new 4K ultra high-definition television displays (UHDTVs) that use quantum dot technology to provide better colour images.

The reason for using quantum dot technology for your displays, instead of LCD or LED displays, is because it’s designed to stop extra light from getting trapped in the internal filter, so it can produce more robust colours without interference.

When they’re being produced for television screens, films of these nanocrystals are arranged between layers of semiconducting materials, so as voltage is applied to the whole arrangement, electrons are free to slot themselves into the quantum dot layer and produce photons, or light particles, says Tarantola.

A special film made from nanocrystals that emit red or green light is added to the front of the screen’s backlight, so when the blue light is shone through them, they combine to produce white light, which interacts with the rest of the quantum dots to produce a colour display. “Generating light via the quantum dots narrows the wavelength of the red and green light produced, meaning less light is caught by the LCD filter,” says Murphy at The Conversation. “This means better colour rendition and brighter colours.”

With the integration of quantum dot technology into consumer electronics, we’re seeing a quick march towards ultra high-definition television displays (UHDTV) – the best contrast, highest saturation, huge range of colours. While LG’s quantum dot television probably won’t be for everyone the moment they come out – people who produce images for a living, such as photographers, film producers, digital artists and graphic designers, will get on it first – the technology will likely replace LCD and LED displays in future years.

Murphy says the reason this technology will so quickly hit the market is because the standards for what makes UHDTV ultra high-definition have already been set. “The ITU-rec 2020 standard for ultra high-definition television allows for higher frame rates of up to 120 fps, higher bit rates and larger contrast and colour gamuts,” he says.

And it’s coming at just the right time. People in broadcast television and cinema already know how to produce ultra high-definition images, but there’s not a whole lot of use doing that if consumers don’t have televisions that can display it properly. Quantum dot televisions will hopefully match everybody up and we can get on with seeing ridiculously beautiful colours the way the future intended.

And the best part? Quantum dots are way cheaper than other high-quality display technologies, such organic light-emitting diodes (OLED), as Tarantola reports at Gizmodo:

“There’s no always-on back light, each quantum dot-lit pixel only turns on when it’s actually needed. This saves as much as 50 percent of the energy needed to illuminate a similarly-sized LCD screen while being 50 to 100 times brighter and expanding the available colour gamut (the total theoretical number of colours a screen can produce) by up to 30 percent.”

So this is happening now, and your huge LED or LCD TV is about to get, as Jerry Seinfeld says, “quite lame”. As Murphy reports at The Conversation, “For 2015 and the foreseeable future, the world’s best video and image reproduction for high-definition content will be delivered with quantum dots.”
