NETS – What are Nanoengineering and Nanotechnology?

is one billionth of a meter, or three to five atoms in width. It would take approximately 40,000 nanometers lined up in a row to equal the width of a human hair. NanoEngineering concerns itself with manipulating processes that occur on the scale of 1-100 nanometers.

The general term, nanotechnology, is sometimes used to refer to common products that have improved properties due to being fortified with nanoscale materials. One example is nano-improved tooth-colored enamel, as used by dentists for fillings. The general use of the term nanotechnology then differs from the more specific sciences that fall under its heading.

NanoEngineering is an interdisciplinary science that builds biochemical structures smaller than bacterium, which function like microscopic factories. This is possible by utilizing basic biochemical processes at the atomic or molecular level. In simple terms, molecules interact through natural processes, and NanoEngineering takes advantage of those processes by direct manipulation.

Red hair – Wikipedia

Red hair (or ginger hair) occurs naturally in 12% of the human population. It occurs more frequently (26%) in people of northern or western European ancestry, and less frequently in other populations. Red hair appears most commonly in people with two copies of a recessive allele on chromosome 16 which produces an altered version of the MC1R protein.[1]

Red hair varies in hues from a deep burgundy or bright copper (reddish-brown or auburn) through to burnt orange or red-orange and strawberry blond. It is characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin. It is associated with fair skin color, lighter eye colors (gray, blue, green, and hazel), freckles, and sensitivity to ultraviolet light.[2]

Cultural reactions have varied from ridicule to admiration; many common stereotypes exist regarding redheads and they are often portrayed as fiery-tempered.

The term redhead has been in use since at least 1510.[3]

Red hair is most commonly found at the northern and western fringes of Europe;[4] it is centered around populations in the British Isles. Redheads today are commonly associated with the Celtic nations[4] and to a far lesser extent the Germanic peoples.

In Ireland, the percentage of population with red hair is estimated to be at around 10%,[5] making it the most red-haired country in the world. According to Britain’s DNA, 34.7% of the Irish population carry the allele for red hair, although this doesn’t directly translate proportionally into births of red-haired children.[6]

Scotland also has a very high percentage with around 6% of the population having red hair.[7][8] Dr. Jim Wilson of Britain’s DNA study used a sample of 2,343 people, and found red hair occurrence of 6% in Scotland, with 36.5% overall carrying the allele and Edinburgh having the highest proportion at 40%.[7][8][6] The largest ever study of hair colour in Scotland, which analysed over 500,000 people, found the percentage of Scots with red hair to be 5.3%.[9]

England has a red hair prevalence of around 4%, with 28.5% of population having the allele;[7] while in Wales 38% of Welsh people carry the red-haired allele.[7] A 1956 study of hair colour among British Army recruits from Great Britain found higher levels of red hair in Wales and the Scottish border counties of England.[fn 1][10]

Carleton Coon’s 1939 book The Races of Europe stated that rufosity (reddish hair) often occurred in Montenegrins.[11][12][13]

In Italy, red hair is found at a frequency of 0.57% of the total population, without variation in frequency across the different regions of the country.[14] In Sardinia, red hair is found at a frequency of 0.24% of the population.[14] Victorian era ethnographers considered the Udmurt people of the Volga Region in Russia to be “the most red-headed men in the world”,[15] a claim which has a solid basis even today, as the Volga region has more redheads per population than anywhere else in the world with the exception of Ireland.[16]

The Berber populations of Morocco[17] and northern Algeria have occasional redheads. Red hair frequency is especially significant among the Riffians from Morocco and Kabyles from Algeria,[18][19][20] respectively. The Queen of Morocco, Lalla Salma wife of king Mohammed VI, has red hair. Abd ar-Rahman I also had red hair, his mother being a Christian Berber slave.

Red hair is also found amongst the Ashkenazi Jewish populations.[21] In 1903, 5.6% of Polish Jews had red hair.[22] Other studies have found that 3.69% of Jewish women overall were found to have red hair, but around 10.9% of all Jewish men have red beards.[23] In European culture, before the 20th century, red hair was often seen as a stereotypically Jewish trait: during the Spanish Inquisition, all those with red hair were identified as Jewish.[24] In Italy, red hair was associated with Italian Jews, and Judas was traditionally depicted as red-haired in Italian and Spanish art.[25] Writers from Shakespeare to Dickens would identify Jewish characters by giving them red hair.[26] The stereotype that red hair is Jewish remains in parts of Eastern Europe and Russia.[27]

In Asia, genetic red hair is rare, but reddish-brown (auburn) hair can be found in the Levant (Syria, Lebanon, Jordan, Israel and Palestine), in Turkey, in Caucasia, in Northern Kazakhstan, and among Uyghurs. The use of henna on hair and skin for various reasons occasionally occurs in Asia. When henna is used on hair it dyes the hair to different shades of red.[28][29]

Emigration from Europe has multiplied the population of red haired humans in the Americas, Australia, New Zealand and South Africa. In the United States, it is estimated that 26% of the population has red hair. This would give the U.S. the largest population of redheads in the world, at 6 to 18 million, compared to approximately 420,000 in Ireland and 300,000 in Scotland.[7]

Several accounts by Greek writers mention redheaded people. A fragment by the poet Xenophanes describes the Thracians as blue-eyed and red-haired.[31] The ancient peoples Budini and Sarmatians are also reported by Greek author to be blue-eyed and red-haired, and the latter even owe their names to it.[32][33]

In Asia, red hair has been found among the ancient Tocharians, who occupied the Tarim Basin in what is now the northwesternmost province of China. Caucasian Tarim mummies have been found with red hair dating to the 2nd millennium BC.[34]

Reddish-brown (auburn) hair is also found amongst some Polynesians, and is especially common in some tribes and family groups. In Polynesian culture reddish hair has traditionally been seen as a sign of descent from high-ranking ancestors and a mark of rulership.[35][36]

The pigment pheomelanin gives red hair its distinctive color. Red hair has far more of the pigment pheomelanin than it has of the dark pigment eumelanin.

The genetics of red hair, discovered in 1997, appear to be associated with the melanocortin-1 receptor (MC1R), which is found on chromosome 16. Red hair is associated with fair skin color because low concentrations of eumelanin throughout the body of those with red hair caused by a MC1R mutation can cause both. The lower melanin concentration in skin confers the advantage that a sufficient concentration of important Vitamin D can be produced under low light conditions. However, when UV-radiation is strong (as in regions close to the equator) the lower concentration of melanin leads to several medical disadvantages, such as a higher risk of skin cancer.

The MC1R recessive variant gene that gives people red hair generally results in skin that is unable to tan. Because of the natural tanning reaction to the sun’s ultraviolet light and high amounts of pheomelanin in the skin, freckles are a common but not all-inclusive feature of red-haired people. Eighty percent of redheads have an MC1R gene variant.[2]

Red hair can originate from several changes on the MC1R-gene. If one of these changes is present on both chromosomes then the respective individual is likely to have red hair. This type of inheritance is described as an autosomal recessive mode of inheritance. Even if both parents do not have red hair themselves, both can be carriers for the gene and have a redheaded child.

Genetic studies of dizygotic (fraternal) twins indicate that the MC1R gene is not solely responsible for the red hair phenotype; unidentified modifier genes exist, making variance in the MC1R gene necessary, but not always sufficient, for red hair production.[37]

The alleles Arg151Cys, Arg160Trp, Asp294His, and Arg142His on MC1R are shown to be recessives for the red hair phenotype.[38] The gene HCL2 (also called RHC or RHA) on chromosome 4 may also be related to red hair.[39][40]

In species other than primates, red hair has different genetic origins and mechanisms.

Red hair is the rarest natural hair color in humans. The non-tanning skin associated with red hair may have been advantageous in far-northern climates where sunlight is scarce. Studies by Bodmer and Cavalli-Sforza (1976) hypothesized that lighter skin pigmentation prevents rickets in colder climates by encouraging higher levels of vitamin D production and also allows the individual to retain heat better than someone with darker skin.[41] In 2000, Harding et al. concluded that red hair is not the result of positive selection but of a lack of negative selection. In Africa, for example, red hair is selected against because high levels of sun harm untanned skin. However, in Northern Europe this does not happen, so redheads can become more common through genetic drift.[38]

Estimates on the original occurrence of the currently active gene for red hair vary from 20,000 to 100,000 years ago.[42][43]

A DNA study has concluded that some Neanderthals also had red hair, although the mutation responsible for this differs from that which causes red hair in modern humans.[44]

A 2007 report in The Courier-Mail, which cited the National Geographic magazine and unnamed “geneticists”, said that red hair is likely to die out in the near future.[45] Other blogs and news sources ran similar stories that attributed the research to the magazine or the “Oxford Hair Foundation”. However, a HowStuffWorks article says that the foundation was funded by hair-dye maker Procter & Gamble, and that other experts had dismissed the research as either lacking in evidence or simply bogus. The National Geographic article in fact states “while redheads may decline, the potential for red isn’t going away”.[46]

Red hair is caused by a relatively rare recessive allele (variant of a gene), the expression of which can skip generations. It is not likely to disappear at any time in the foreseeable future.[46]

Melanin in the skin aids UV tolerance through suntanning, but fair-skinned persons lack the levels of melanin needed to prevent UV-induced DNA-damage. Studies have shown that red hair alleles in MC1R increase freckling and decrease tanning ability.[47] It has been found that Europeans who are heterozygous for red hair exhibit increased sensitivity to UV radiation.[48]

Red hair and its relationship to UV sensitivity are of interest to many melanoma researchers. Sunshine can both be good and bad for a person’s health and the different alleles on MC1R represent these adaptations. It also has been shown that individuals with pale skin are highly susceptible to a variety of skin cancers such as melanoma, basal cell carcinoma, and squamous cell carcinoma.[49][50]

Two studies have demonstrated that people with red hair have different sensitivity to pain compared to people with other hair colors. One study found that people with red hair are more sensitive to thermal pain (associated with naturally occurring low vitamin K levels),[51] while another study concluded that redheads are less sensitive to pain from multiple modalities, including noxious stimuli such as electrically induced pain.[52][53][54]

Researchers have found that people with red hair require greater amounts of anesthetic.[55] Other research publications have concluded that women with naturally red hair require less of the painkiller pentazocine than do either women of other hair colors or men of any hair color. A study showed women with red hair had a greater analgesic response to that particular pain medication than men.[56] A follow-up study by the same group showed that men and women with red hair had a greater analgesic response to morphine-6-glucuronide.[54]

The unexpected relationship of hair color to pain tolerance appears to exist because redheads have a mutation in a hormone receptor that can apparently respond to at least two types of hormones: the pigmentation-driving melanocyte-stimulating hormone (MSH), and the pain-relieving endorphins. (Both derive from the same precursor molecule, POMC, and are structurally similar.) Specifically, redheads have a mutated melanocortin-1 receptor (MC1R) gene that produces an altered receptor for MSH.[57] Melanocytes, the cells that produce pigment in skin and hair, use the MC1R to recognize and respond to MSH from the anterior pituitary gland. Melanocyte-stimulating hormone normally stimulates melanocytes to make black eumelanin, but if the melanocytes have a mutated receptor, they will make reddish pheomelanin instead. MC1R also occurs in the brain, where it is one of a large set of POMC-related receptors that are apparently involved not only in responding to MSH, but also in responses to endorphins and possibly other POMC-derived hormones.[57] Though the details are not clearly understood, it appears that there is some crosstalk between the POMC hormones; this may explain the link between red hair and pain tolerance.

There is little or no evidence to support the belief that people with red hair have a higher chance than people with other hair colors to hemorrhage or suffer other bleeding complications.[58][59] One study, however, reports a link between red hair and a higher rate of bruising.[59]

Most red hair is caused by the MC1R gene and is non-pathological. However, in rare cases red hair can be associated with disease or genetic disorder:

In various times and cultures, red hair has been prized, feared, and ridiculed.

A common belief about redheads is that they have fiery tempers and sharp tongues. In Anne of Green Gables, a character says of Anne Shirley, the redheaded heroine, that “her temper matches her hair”, while in The Catcher in the Rye, Holden Caulfield remarks that “People with red hair are supposed to get mad very easily, but Allie [his dead brother] never did, and he had very red hair.”

During the early stages of modern medicine, red hair was thought to be a sign of a sanguine temperament.[64] In the Indian medicinal practice of Ayurveda, redheads are seen as most likely to have a Pitta temperament.

Another belief is that redheads are highly sexed; for example, Jonathan Swift satirizes redhead stereotypes in part four of Gulliver’s Travels, “A Voyage to the Country of the Houyhnhnms,” when he writes that: “It is observed that the red-haired of both sexes are more libidinous and mischievous than the rest, whom yet they much exceed in strength and activity.” Swift goes on to write that “neither was the hair of this brute [a Yahoo] of a red colour (which might have been some excuse for an appetite a little irregular) but black as a sloe”.[65] Such beliefs were given a veneer of scientific credibility in the 19th century by Cesare Lombroso and Guglielmo Ferrero. They concluded that red hair was associated with crimes of lust, and claimed that 48% of “criminal women” were redheads.[66]

Queen Elizabeth I of England was a redhead, and during the Elizabethan era in England, red hair was fashionable for women. In modern times, red hair is subject to fashion trends; celebrities such as Nicole Kidman, Alyson Hannigan, Marcia Cross, Christina Hendricks, Emma Stone and Geri Halliwell can boost sales of red hair dye.[citation needed]

Sometimes, red hair darkens as people get older, becoming a more brownish color or losing some of its vividness. This leads some to associate red hair with youthfulness, a quality that is generally considered desirable. In several countries such as India, Iran, Bangladesh and Pakistan, henna and saffron are used on hair to give it a bright red appearance.[67]

Many painters have exhibited a fascination with red hair. The hair color “Titian” takes its name from the artist Titian, who often painted women with red hair. Early Renaissance artist Sandro Botticelli’s famous painting The Birth of Venus depicts the mythological goddess Venus as a redhead. Other painters notable for their redheads include the Pre-Raphaelites, Edmund Leighton, Modigliani,[68] and Gustav Klimt.[69]

Sir Arthur Conan Doyle’s Sherlock Holmes story “The Red-Headed League” (1891) involves a man who is asked to become a member of a mysterious group of red-headed people. The 1943 film DuBarry Was a Lady featured red-heads Lucille Ball and Red Skelton in Technicolor.

Notable fictional characters with red hair includes Red Sonja, Mystique, and Poison Ivy.[70]

Red hair was thought to be a mark of a beastly sexual desire and moral degeneration. A savage red-haired man is portrayed in the fable by Grimm brothers (Der Eisenhans) as the spirit of the forest of iron. Theophilus Presbyter describes how the blood of a red-haired young man is necessary to create gold from copper, in a mixture with the ashes of a basilisk.[71]

Montague Summers, in his translation of the Malleus Maleficarum,[72] notes that red hair and green eyes were thought to be the sign of a witch, a werewolf or a vampire during the Middle Ages;

Those whose hair is red, of a certain peculiar shade, are unmistakably vampires. It is significant that in ancient Egypt, as Manetho tells us, human sacrifices were offered at the grave of Osiris, and the victims were red-haired men who were burned, their ashes being scattered far and wide by winnowing-fans. It is held by some authorities that this was done to fertilize the fields and produce a bounteous harvest, red-hair symbolizing the golden wealth of the corn. But these men were called Typhonians, and were representatives not of Osiris but of his evil rival Typhon, whose hair was red.

During the Spanish Inquisition, people of red hair were identified as Jewish and isolated for persecution.[24] In Medieval Italy and Spain, red hair was associated with the heretical nature of Jews and their rejection of Jesus, and thus Judas Iscariot was commonly depicted as red-haired in Italian and Spanish art.[25] Writers from Shakespeare to Dickens would identify Jewish characters by giving them red hair, with red-hair being given by the authors to villainous Jewish characters such as Shylock and Fagin.[26] The antisemitic association persisted into modern times in Soviet Russia.[27] The medieval prejudice against red-hair may have derived from the Ancient biblical tradition, in relation to biblical figures such as Esau and King David. The Ancient historian Josephus would mistranslate the Hebrew Torah to describe the more positive figure of King David as ‘golden haired’, in contrast to the negative figure of Esau, even though the original Hebrew Torah implies that both King David and Esau had ‘fiery red hair’.[73]

In his 1885 book I Say No, Wilkie Collins wrote “The prejudice against habitual silence, among the lower order of the people, is almost as inveterate as the prejudice against red hair.”

In his 1895 memoir and history The Gurneys of Earlham, Augustus John Cuthbert Hare described an incident of harassment:”The second son, John, was born in 1750. As a boy he had bright red hair, and it is amusingly recorded that one day in the streets of Norwich a number of boys followed him, pointing to his red locks and saying, “Look at that boy; he’s got a bonfire on the top of his head,” and that John Gurney was so disgusted that he went to a barber’s, had his head shaved, and went home in a wig. He grew up, however, a remarkably attractive-looking young man.”[74]

In British English, the word “ginger” is sometimes used to describe red-headed people (at times in an insulting manner),[75] with terms such as “gingerphobia”[76] and “gingerism”[77] used by the British media. In Britain, redheads are also sometimes referred to disparagingly as “carrot tops” and “carrot heads”. (The comedian “Carrot Top” uses this stage name.) “Gingerism” has been compared to racism, although this is widely disputed, and bodies such as the UK Commission for Racial Equality do not monitor cases of discrimination and hate crimes against redheads.[77]

Nonetheless, individuals and families in Britain are targeted for harassment and violence because of their hair colour. In 2003, a 20-year-old was stabbed in the back for “being ginger”.[78] In 2007, a UK woman won an award from a tribunal after being sexually harassed and receiving abuse because of her red hair;[79] in the same year, a family in Newcastle upon Tyne, was forced to move twice after being targeted for abuse and hate crime on account of their red hair.[80] In May 2009, a schoolboy committed suicide after being bullied for having red hair.[81] In 2013, a fourteen-year-old boy in Lincoln had his right arm broken and his head stamped on by three men who attacked him “just because he had red hair”. The three men were subsequently jailed for a combined total of ten years and one month for the attack.[82]

This prejudice has been satirised on a number of TV shows. The British comedian Catherine Tate (herself a redhead) appeared as a red-haired character in a running sketch of her series The Catherine Tate Show. The sketch saw fictional character Sandra Kemp, who was forced to seek solace in a refuge for ginger people because she had been ostracised from society.[83] The British comedy Bo’ Selecta! (starring redhead Leigh Francis) featured a spoof documentary which involved a caricature of Mick Hucknall presenting a show in which celebrities (played by themselves) dyed their hair red for a day and went about daily life being insulted by people.(Hucknall, who says that he has repeatedly faced prejudice or been described as ugly on account of his hair colour, argues that Gingerism should be described as a form of racism.[84][85]) Comedian Tim Minchin, himself a redhead, also covered the topic in his song “Prejudice”.[86]

The pejorative use of the word “ginger” and related discrimination was used to illustrate a point about racism and prejudice in the “Ginger Kids”, “Le Petit Tourette”, “It’s a Jersey Thing” and “Fatbeard” episodes of South Park.

Film and television programmes often portray school bullies as having red hair.[87] However, children with red hair are often themselves targeted by bullies; “Somebody with ginger hair will stand out from the crowd,” says anti-bullying expert Louise Burfitt-Dons.[88]

In Australian slang, redheads are often nicknamed “Blue” or “Bluey”.[89] More recently, they have been referred to as “rangas” (a word derived from the red-haired ape, the orangutan), sometimes with derogatory connotations.[90] The word “rufus” has been used in both Australian and British slang to refer to red-headed people;[91] based on a variant of rufous, a reddish-brown color.

In November 2008 social networking website Facebook received criticism after a ‘Kick a Ginger’ group, which aimed to establish a “National Kick a Ginger Day” on 20 November, acquired almost 5,000 members. A 14-year-old boy from Vancouver who ran the Facebook group was subjected to an investigation by the Royal Canadian Mounted Police for possible hate crimes.[92]

In December 2009 British supermarket chain Tesco withdrew a Christmas card which had the image of a child with red hair sitting on the lap of Santa Claus, and the words: “Santa loves all kids. Even ginger ones” after customers complained the card was offensive.[93]

In October 2010, Harriet Harman, the former Equality Minister in the British government under Labour, faced accusations of prejudice after she described the red-haired Treasury secretary Danny Alexander as a “ginger rodent”.[94] Alexander responded to the insult by stating that he was “proud to be ginger”.[95] Harman was subsequently forced to apologise for the comment, after facing criticism for prejudice against a minority group.[96]

In September 2011, Cryos International, one of the world’s largest sperm banks, announced that it would no longer accept donations from red-haired men due to low demand from women seeking artificial insemination.[97]

The term ang mo (Chinese: ; pinyin: hng mo; Peh-e-j: ng-mo) in Hokkien (Min Nan) Chinese means “red-haired”,[98] and is used in Malaysia and Singapore to refer to white people. The epithet is sometimes rendered as ang mo kui () meaning “red-haired devil”, similar to the Cantonese term gweilo (“foreign devil”). Thus it is viewed as racist and derogatory by some people.[99] Others, however, maintain it is acceptable.[100] Despite this ambiguity, it is a widely used term. It appears, for instance, in Singaporean newspapers such as The Straits Times,[101] and in television programmes and films.

The Chinese characters for ang mo are the same as those in the historical Japanese term Km (), which was used during the Edo period (16031868) as an epithet for Dutch or Northern European people. It primarily referred to Dutch traders who were the only Europeans allowed to trade with Japan during Sakoku, its 200-year period of isolation.[102]

There has been an annual Redhead Day festival in the Netherlands that attracts red-haired participants from around the world. The festival is paid for by the local government in Breda, a city in the south east of the Netherlands.[103] It attracts participants from over 80 different countries. The international event began in 2005, when Dutch painter Bart Rouwenhorst decided he wanted to paint 15 redheads. Today, the festival includes music, fashion shows, art exhibitions and a picnic[104]

The Irish Redhead Convention, held in late August in County Cork since 2011, claims to be a global celebration and attracts people from several continents. The celebrations include crowning the ginger King and Queen, competitions for the best red eyebrows and most freckles per square inch, orchestral concerts and carrot throwing competitions.[105]

A smaller red-hair day festival is held since 2013 by the UK’s anti bullying alliance in London, with the aim of instilling pride in having red-hair.[106]

Since 2014, a red-hair event is held in Israel, at Kibbutz Gezer (Carrot), held for the local Israeli red hair community,[107] including both Ashkenazi and Mizrahi red-heads.[108] However, the number of attendees has to be restricted due to the risk of rocket attacks, leading to anger in the red-hair community.[109] The organizers state; “The event is a good thing for many redheads, who had been embarrassed about being redheads before.[109]

The first and only festival for red heads in the United States was launched in 2015. Held in Highwood, Illinois, Redhead Days draws participants from across the United States.[110]

A festival to celebrate the red-haired people is held annually in Izhevsk (Russia), the capital of Udmurtia, since 2004.[111]

In the Iliad, Achilles’ hair is described as [112] (ksanths), usually translated as blonde, or golden[113] but sometimes as red or tawny.[114][115] His son Neoptolemus also bears the name Pyrrhus, a possible reference to his own red hair.[116]

The Norse god Thor is usually described as having red hair.[117]

The Hebrew word usually translated “ruddy” or “reddish-brown” (admoni , from the root ADM , see also Adam and Edom)[118][119][120] was used to describe both Esau and David.

Early artistic representations of Mary Magdalene usually depict her as having long flowing red hair, although a description of her hair color was never mentioned in the Bible, and it is possible the color is an effect caused by pigment degradation in the ancient paint.

Judas Iscariot is also represented with red hair in Spanish culture[121][122] and in the works of William Shakespeare,[123] reinforcing the negative stereotype.

Robot Security Guards Will Constantly Nag Spectators at the Tokyo Olympics

Over and Over

“The security robot is patrolling. Ding-ding. Ding-ding. The security robot is patrolling. Ding-ding. Ding-ding.”

That’s what Olympic attendees will hear ad nauseam when they step onto the platforms of Tokyo’s train stations in 2020. The source: Perseusbot, a robot security guard Japanese developers unveiled to the press on Thursday.

Observe and Report

According to reporting by Kyodo News, the purpose of the AI-powered Perseusbot is to lower the burden on the stations’ staff when visitors flood Tokyo during the 2020 Olympics.

The robot is roughly 5.5 feet tall and equipped with security cameras that allow it to note suspicious behaviors, such as signs of violence breaking out or unattended packages, as it autonomous patrols the area. It can then alert security staff to the issues by sending notifications directly to their smart phones.

Prior Prepration

Just like the athletes who will head to Tokyo in 2020, Perseusbot already has a training program in the works — it’ll patrol Tokyo’s Seibu Shinjuku Station from November 26 to 30. This dry run should give the bot’s developers a chance to work out any kinks before 2020.

If all goes as hoped, the bot will be ready to annoy attendees with its incessant chant before the Olympic torch is lit. And, you know, keep everyone safe, too.

People Would Rather a Self-Driving Car Kill a Criminal Than a Dog

Snap Decisions

On first glance, a site that collects people’s opinions about whose life an autonomous car should favor doesn’t tell us anything we didn’t already know. But look closer, and you’ll catch a glimpse of humanity’s dark side.

The Moral Machine is an online survey designed by MIT researchers to gauge how the public would want an autonomous car to behave in a scenario in which someone has to die. It asks questions like: “If an autonomous car has to choose between killing a man or a woman, who should it kill? What if the woman is elderly but the man is young?”

Essentially, it’s a 21st century update on the Trolley Problem, an ethical thought experiment no doubt permanently etched into the mind of anyone who’s seen the second season of “The Good Place.”

Ethical Dilemma

The MIT team launched the Moral Machine in 2016, and more than two million people from 233 countries participated in the survey — quite a significant sample size.

On Wednesday, the researchers published the results of the experiment in the journal Nature, and they really aren’t all that surprising: Respondents value the life of a baby over all others, with a female child, male child, and pregnant woman following closely behind. Yawn.

It’s when you look at the other end of the spectrum — the characters survey respondents were least likely to “save” — that you’ll see something startling: Survey respondents would rather the autonomous car kill a human criminal than a dog.

Ugly Reflection

While the team designed the survey to help shape the future of autonomous vehicles, it’s hard not to focus on this troubling valuing of a dog’s life over that of any human, criminal or not. Does this tell us something important about how society views the criminal class? Reveal that we’re all monsters when hidden behind the internet’s cloak of anonymity? Confirm that we really like dogs?

The MIT team doesn’t address any of these questions in their paper, and really, we wouldn’t expect them to — it’s their job to report the survey results, not extrapolate some deeper meaning from them. But whether the Moral Machine informs the future of autonomous vehicles or not, it’s certainly held up a mirror to humanity’s values, and we do not like the reflection we see.

Scientists Say New Material Could Hold up an Actual Space Elevator

Space Elevator

It takes a lot of energy to put stuff in space. That’s why one longtime futurist dream is a “space elevator” — a long cable strung between a geostationary satellite and the Earth that astronauts could use like a dumbwaiter to haul stuff up into orbit.

The problem is that such a system would require an extraordinarily light, strong cable. Now, researchers from Beijing’s Tsinghua University say they’ve developed a carbon nanotube fiber so sturdy and lightweight that it could be used to build an actual space elevator.

Going Up

The researchers published their paper in May, but it’s now garnering the attention of their peers. Some believe the Tsinghua team’s material really could lead to the creation of an elevator that would make it cheaper to move astronauts and materials into space.

“This is a breakthrough,” colleague Wang Changqing, who studies space elevators at Northwestern Polytechnical University, told the South China Morning Post.

Huge If True

There are still countless galling technical problems that need to be overcome before a space elevator would start to look plausible. Wang pointed out that it’d require tens of thousands of kilometers of the new material, for instance, as well as a shield to protect it from space debris.

But the research brings us one step closer to what could be a true game changer: a vastly less expensive way to move people and spacecraft out of Earth’s gravity.

AI Dreamed Up These Nightmare Fuel Halloween Masks

Nightmare Fuel

Someone programmed an AI to dream up Halloween masks, and the results are absolute nightmare fuel. Seriously, just look at some of these things.

“What’s so scary or unsettling about it is that it’s not so detailed that it shows you everything,” said Matt Reed, the creator of the masks, in an interview with New Scientist. “It leaves just enough open for your imagination to connect the dots.”

Creative Horror

To create the masks, Reed — whose day job is as a technologist at a creative agency called redpepper — fed an open source AI tool 5,000 pictures of Halloween masks he sourced from Google Images. He then instructed the tool to generate its own masks.

The fun and spooky project is yet another sign that AI is coming into its own as a creative tool. Just yesterday, a portrait generated by a similar system fetched more than $400,000 at a prominent British auction house.

And Reed’s masks are evocative. Here at the Byte, if we looked through the peephole and saw one of these on a trick or treater, we might not open our door.

FBI’s Tesla Criminal Probe Reportedly Centers on Model 3 Production

Ups and Downs

Can we please get off Mr. Musk’s Wild Ride now? We don’t know how much more of this Tesla rollercoaster we can take.

In 2018 alone, Elon Musk’s clean energy company has endured a faulty flufferbot, furious investors, and an SEC probe and settlement. But there was good news, too. Model 3 deliveries reportedly increased, and just this week, we found out that Tesla had a historic financial quarter, generating $312 million in profit.

And now we’re plummeting again.

Closing In

On Friday, The Wall Street Journal reported that the Federal Bureau of Investigation (FBI) is deepening a criminal probe into whether Tesla “misstated information about production of its Model 3 sedans and misled investors about the company’s business going back to early 2017.”

We’ve known about the FBI’s Tesla criminal probe since September 18, but this is the first report confirming that Model 3 production is at the center of the investigation.

According to the WSJ’s sources, FBI agents have been reaching out to former Tesla employees in recent weeks to ask if they’d be willing to testify in the criminal case, though no word yet on whether any have agreed.

Casual CEO

We might be having trouble keeping up with these twists and turns, but Musk seems to be taking the FBI’s Tesla criminal probe all in stride — he spent much of Friday afternoon joking around with his Twitter followers about dank memes.

Clearly he has the stomach for this, but it’d be hard to blame any Tesla investors for deciding they’d had enough.

Zero Gravity Causes Worrisome Changes In Astronauts’ Brains

Danger, Will Robinson

As famous Canadian astronaut Chris Hadfield demonstrated with his extraterrestrial sob session, fluids behave strangely in space.

And while microgravity makes for a great viral video, it also has terrifying medical implications that we absolutely need to sort out before we send people into space for the months or years necessary for deep space exploration.

Specifically, research published Thursday In the New England Journal of Medicine demonstrated that our brains undergo lasting changes after we spend enough time in space. According to the study, cerebrospinal fluid — which normally cushions our brain and spinal cord — behaves differently in zero gravity, causing it to pool around and squish our brains.

Mysterious Symptoms

The brains of the Russian cosmonauts who were studied in the experiment mostly bounced back upon returning to Earth.

But even seven months later, some abnormalities remained. According to National Geographic, the researchers suspect that high pressure  inside the cosmonauts’ skulls may have squeezed extra water into brain cells which later drained out en masse.

Now What?

So far, scientists don’t know whether or not this brain shrinkage is related to any sort of cognitive or other neurological symptoms — it might just be a weird quirk of microgravity.

But along with other space hazards like deadly radiation and squished eyeballs, it’s clear that we have a plethora of medical questions to answer before we set out to explore the stars.

We Aren’t Growing Enough Healthy Foods to Feed Everyone on Earth

Check Yourself

The agriculture industry needs to get its priorities straight.

According to a newly published study, the world food system is producing too many unhealthy foods and not enough healthy ones.

“We simply can’t all adopt a healthy diet under the current global agriculture system,” said study co-author Evan Fraser in a press release. “Results show that the global system currently overproduces grains, fats, and sugars, while production of fruits and vegetables and, to a smaller degree, protein is not sufficient to meet the nutritional needs of the current population.”

Serving Downsized

For their study, published Tuesday in the journal PLOS ONE, researchers from the University of Guelph compared global agricultural production with consumption recommendations from Harvard University’s Healthy Eating Plate guide. Their findings were stark: The agriculture industry’s overall output of healthy foods does not match humanity’s needs.

Instead of the recommended eight servings of grains per person, it produces 12. And while nutritionists recommend we each consume 15 servings of fruits and vegetables daily, the industry produces just five. The mismatch continues for oils and fats (three servings instead of one), protein (three servings instead of five), and sugar (four servings when we don’t need any).

Overly Full Plate

The researchers don’t just point out the problem, though — they also calculated what it would take to address the lack of healthy foods while also helping the environment.

“For a growing population, our calculations suggest that the only way to eat a nutritionally balanced diet, save land, and reduce greenhouse gas emission is to consume and produce more fruits and vegetables as well as transition to diets higher in plant-based protein,” said Fraser.

A number of companies dedicated to making plant-based proteins mainstream are already gaining traction. But unfortunately, it’s unlikely that the agriculture industry will decide to prioritize growing fruits and veggies over less healthy options as long as people prefer having the latter on their plates.

Report Identifies China as the Source of Ozone-Destroying Emissions

Emissions Enigma

For years, a mystery puzzled environmental scientists. The world had banned the use of many ozone-depleting compounds in 2010. So why were global emission levels still so high?

The picture started to clear up in June. That’s when The New York Times published an investigation into the issue. China, the paper claimed, was to blame for these mystery emissions. Now it turns out the paper was probably right to point a finger.

Accident or Incident

In a paper published recently in the journal Geophysical Research Letters, an international team of researchers confirms that eastern China is the source of at least half of the 40,000 tonnes of carbon tetrachloride emissions currently entering the atmosphere each year.

They figured this out using a combination of ground-based and airborne atmospheric concentration data from near the Korean peninsula. They also relied on two models that simulated how the gases would move through the atmosphere.

Though they were able to narrow down the source to China, the researchers weren’t able to say exactly who’s breaking the ban and whether they even know about the damage they’re doing.

Pinpoint

“Our work shows the location of carbon tetrachloride emissions,” said co-author Matt Rigby in a press release. “However, we don’t yet know the processes or industries that are responsible. This is important because we don’t know if it is being produced intentionally or inadvertently.”

If we can pinpoint the source of these emissions, we can start working on stopping them and healing our ozone. And given that we’ve gone nearly a decade with minimal progress on that front, there’s really no time to waste.

An AI Conference Refusing a Name Change Highlights a Tech Industry Problem

Name Game

There’s a prominent artificial intelligence conference that goes by the suggestive acronym NIPS, which stands for “Neural Information Processing Systems.”

After receiving complaints that the acronym was alienating to women, the conference’s leadership collected suggestions for a new name via an online poll, according to WIRED. But the conference announced Monday that it would be sticking with NIPS all the same.

Knock It Off

It’s convenient to imagine that this acronym just sort of emerged by coincidence, but let’s not indulge in that particular fantasy.

It’s more likely that tech geeks cackled maniacally when they came up with the acronym, and the refusal to do better even when people looking up the conference in good faith are bombarded with porn is a particularly telling failure of the AI research community.

Small Things Matter

This problem goes far beyond a silly name — women are severely underrepresented in technology research and even more so when it comes to artificial intelligence. And if human decency — comforting those who are regularly alienated by the powers that be — isn’t enough of a reason to challenge the sexist culture embedded in tech research, just think about what we miss out on.

True progress in artificial intelligence cannot happen without a broad range of diverse voices — voices that are silenced by “locker room talk” among an old boy’s club. Otherwise, our technological development will become just as stuck in place as our cultural development often seems to be.

Scientists Are Hopeful AI Could Help Predict Earthquakes

Quake Rate

Earlier this year, I interviewed U.S. Geological Survey geologist Annemarie Baltay for a story about why it’s incredibly difficult to predict earthquakes.

“We don’t use that ‘p word’ — ‘predict’ — at all,” she told me. “Earthquakes are chaotic. We don’t know when or where they’ll occur.”

Neural Earthwork

That could finally be starting to change, according to a fascinating feature in The New York Times.

By feeding seismic data into a neural network — a type of artificial intelligence that learns to recognize patterns by scrutinizing examples — researchers say they can now predict moments after a quake strikes how far its aftershocks will travel.

And eventually, some believe, they’ll be able to listen to signals from fault lines and predict when an earthquake will strike in the first place.

Future Vision

But like Baltay, some researchers aren’t convinced we’ll ever be able to predict earthquakes.University of Tokyo seismologist Robert Geller told the Times that until an algorithm actually predicts an upcoming quake, he’ll remain skeptical.

“There are no shortcuts,” he said. “If you cannot predict the future, then your hypothesis is wrong.”

A Stem Cell Transplant Let a Wheelchair-Bound Man Dance Again

Stand Up Guy

For 10 years, Roy Palmer had no feeling in his lower extremities. Two days after receiving a stem cell transplant, he cried tears of joy because he could feel a cramp in his leg.

The technical term for the procedure the British man underwent is hematopoietic stem cell transplantation (HSCT). And while risky, it’s offering new hope to people like Palmer, who found himself wheelchair-bound after multiple sclerosis (MS) caused his immune system to attack his nerves’ protective coverings.

Biological Reboot

Ever hear the IT troubleshooting go-to of turning a system off and on again to fix it? The HSCT process is similar, but instead of a computer, doctors attempt to reboot a patient’s immune system.

To do this, they first remove stem cells from the patient’s body. Then the patient undergoes chemotherapy, which kills the rest of their immune system. After that, the doctors use the extracted stem cells to reboot the patient’s immune system.

It took just two days for the treatment to restore some of the feeling in Palmer’s legs. Eventually, he was able to walk on his own and even dance. He told the BBC in a recent interview that he now feels like he has a second chance at life.

“We went on holiday, not so long ago, to Turkey. I walked on the beach,” said Palmer. “Little things like that, people do not realize what it means to me.”

Risk / Reward

Still, HSCT isn’t some miracle cure for MS. Though it worked for Palmer, that’s not always the case, and HSCT can also cause infections and infertility. The National MS Society still considers HSCT to be an experimental treatment, and the Food and Drug Administration has yet to approve the therapy in the U.S.

However, MS affects more than 2.3 million people, and if a stem cell transplant can help even some of those folks the way it helped Palmer, it’s a therapy worth exploring.

This AI Lie Detector Flags Falsified Police Reports

Minority Report

Imagine this: You file a police report, but back at the station, they feed it into an algorithm — and it accuses you of lying, as though it had somehow looked inside your brain.

That might sound like science fiction, but Spain is currently rolling out a very similar program, called VeriPol, in many of its police stations. VeriPol’s creators say that when it flags a report as false, it turns out to be correct more than four-fifths of the time.

Lie Detector

VeriPol is the work of researchers at Cardiff University and Charles III University of Madrid.

In a paper published earlier this year in the journal Knowledge-Based Systems, they describe how they trained the lie detector with a data set of more than 1,000 robbery reports — including a number that police identified as false — to identify subtle signs that a report wasn’t true.

Thought Crime

In pilot studies in Murcia and Malaga, Quartz reported, further investigation showed that the algorithm was correct about 83 percent of the time that it suspected a report was false.

Still, the project raises uncomfortable questions about allowing algorithms to act as lie detectors. Fast Company reported earlier this year that authorities in the United States, Canada, and the European Union are testing a separate system called AVATAR that they want to use to collect biometric data about subjects at border crossings — and analyze it for signs that they’re not being truthful.

Maybe the real question isn’t whether the tech works, but whether we want to permit authorities to act upon what’s essentially a good — but not perfect — assumption that someone is lying.

These Bacteria Digest Food Waste Into Biodegradable Plastic

Factory Farm

Plastics have revolutionized manufacturing, but they’re still terrible for the environment.

Manufacturing plastics is an energy-intensive slog that ends in mountains of toxic industrial waste and greenhouse gas emissions. And then the plastic itself that we use ends up sitting in a garbage heap for thousands of years before it biodegrades.

Scientists have spent years investigating ways to manufacture plastics without ruining the planet, and a Toronto biotech startup called Genecis says it’s found a good answer: factories where vats of bacteria digest food waste and use it to form biodegradable plastic in their tiny microbial guts.

One-Two Punch

The plastic-pooping bacteria stand to clean up several kinds of pollution while churning out usable materials, according to Genecis.

That’s because the microbes feed on waste food or other organic materials — waste that CBC reported gives off 20 percent of Canada’s methane emissions as it sits in landfills.

Then What?

The plastic that the little buggers produce isn’t anything new. It’s called PHA and it’s used in anything that needs to biodegrade quickly, like those self-dissolving stitches. What’s new here is that food waste is much cheaper than the raw materials that usually go into plastics, leading Genecis to suspect it can make the same plastics for 40 percent less cost.

There are a lot of buzzworthy new alternative materials out there, but with a clear environmental and financial benefit, it’s possible these little bacteria factories might be here to stay.

You Can Now Preorder a $150,000 Hoverbike

Please, Santa?

It’s never too early to start writing your Christmas wish list, right? Because we know what’s now at the top of ours: a hoverbike.

We’ve had our eyes on Hoversurf’s Scorpion-3 since early last year — but now, the Russian drone start-up is accepting preorders on an updated version of the vehicle.

Flying Bike

The S3 2019 is part motorcycle and part quadcopter. According to the Hoversurf website, the battery-powered vehicle weighs 253 pounds and has a flight time of 10 to 25 minutes depending on operator weight. Its maximum legal speed is 60 mph — though as for how fast the craft can actually move, that’s unknown. Hoversurf also notes that the vehicle’s “safe flight altitude” is 16 feet, but again, we aren’t sure how high it can actually soar.

What we do know: The four blades that provide S3 with its lift spin at shin level, and while this certainly looks like it would be a safety hazard, the U.S. Department of Transportation’s Federal Aviation Administration approved the craft for legal use as an ultralight vehicle in September.

That means you can only operate an S3 for recreational or sports purposes — but you can’t cruise to work on your morning commute.

Plummeting Bank Account

You don’t need a pilot’s license to operate an S3, but you will need a decent amount of disposable income — the Star Wars-esque craft will set you back $150,000.

If that number doesn’t cause your eyes to cross, go ahead and slap down the $10,000 deposit needed to claim a spot in the reservation queue. You’ll then receive an email when it’s time to to place your order. You can expect to receive your S3 2019 two to six months after that, according to the company website.

That means there’s a pretty good chance you won’t be able to hover around your front yard this Christmas morning, but a 2019 jaunt is a genuine possibility.

WHO Director: Air Pollution Is the “New Tobacco”

Wrong Direction

Breathing polluted air is as likely to kill you as tobacco use — worldwide, each kills about 7 million people annually. But while the world is making progress in the war against tobacco, air pollution is getting worse.

The Director General of the World Health Organization (WHO) hopes to change that.

“The world has turned the corner on tobacco,” wrote Tedros Adhanom Ghebreyesus in an opinion piece published by The Guardian on Saturday. “Now it must do the same for the ‘new tobacco’ — the toxic air that billions breathe every day.”

Taking Action

According to the WHO, nine out of 10 people in the world breathe polluted air.

This week, the organization is hosting the first Global Conference on Air Pollution and Health, and Ghebreyesus is hopeful world leaders will use the conference as the opportunity to commit to cutting air pollution in their nations.

“Despite the overwhelming evidence, political action is still urgently needed to boost investments and speed up action to reduce air pollution,” he wrote, noting that this action could take the form of more stringent air quality standards, improved access to clean energy, or increased investment in green technologies.

Reduced Risk

The impact sustained action against air pollution could have on public health is hard to overstate.

“No one, rich or poor, can escape air pollution. A clean and healthy environment is the single most important precondition for ensuring good health,” wrote Ghebreyesus in his Guardian piece. “By cleaning up the air we breathe, we can prevent or at least reduce some of the greatest health risks.”

The conference ends on Thursday, so we won’t have to wait long to see which nations do — or don’t — heed the WHO’s call to action.

Scientists May Have Put Microbes in a State of Quantum Entanglement

Hall of Mirrors

A few years ago, the journal Small published a study showing how photosynthetic bacteria could absorb and release photons as the light bounced across a minuscule gap between two mirrors.

Now, a retroactive look at the study’s data published in The Journal of Physics Communications suggests something more may have been going on. The bacteria may have been the first living organisms to operate in the realm of quantum physics, becoming entangled with the bouncing light at the quantum scale.

Cat’s Cradle

The experiment in question, as described by Scientific American, involved individual photons — the smallest quantifiable unit of light that can behave like a tiny particle but also a wave of energy within quantum physics — bouncing between two mirrors separated by a microscopic distance.

But a look at the energy levels in the experimental setup suggests that the bacteria may have become entangled, as some individual photons seem to have simultaneously interacted with and missed the bacterium at the same time.

Super Position

There’s reason to be skeptical of these results until someone actually recreates the experiment while looking for signs of quantum interactions. As with any look back at an existing study, scientists are restricted to the amount and quality of data that was already published. And, as Scientific American noted, the energy levels of the bacteria and the mirror setup should have been recorded individually — which they were not — in order to verify quantum entanglement.

But if this research holds up, it would be the first time a life form operated on the realm of quantum physics, something usually limited to subatomic particles. And even though the microbes are small, that’s a big deal.

There’s No Way China’s Artificial Moon Will Work, Says Expert

Good Luck

On October 10, a Chinese organization called the Tian Fu New Area Science Society revealed plans to replace the streetlights in the city of Chengdu with a satellite designed to reflect sunlight toward the Earth’s surface at night.

But in a new interview with Astronomy, an associate professor of aerospace engineering at the University of Texas at Austin named Ryan Russel argued that based on what he’s read, the artificial moon plan would be impossible to implement.

Promised the Moon

Wu Chunfeng, the head of the Tian Fu New Area Science Society, told China Daily the artificial moon would orbit about 310 miles above Earth, delivering an expected brightness humans would perceive to be about one-fifth that of a typical streetlight.

The plan is to launch one artificial moon in 2020 and then three more in 2022 if the first works as hoped. Together, these satellites could illuminate an area of up to 4,000 square miles, Chunfeng claims.

But Russell is far from convinced.

“Their claim for 1 [low-earth orbit satellite] at [300 miles] must be a typo or misinformed spokesperson,” he told Astronomy. “The article I read implied you could hover a satellite over a particular city, which of course is not possible.”

Overkill Overhead

To keep the satellite in place over Chengdu, it would need to be about 22,000 miles above the Earth’s surface, said Russel, and its reflective surface would need to be massive to reflect sunlight from that distance. At an altitude of just 300 miles, the satellite would quickly zip around the Earth, constantly illuminating new locations.

Even if the city could put the artificial moon plan into action, though, Russell isn’t convinced it should.

“It’s a very complicated solution that affects everyone to a simple problem that affects a few,” he told Astronomy. “It’s light pollution on steroids.”

Maybe Chengdu shouldn’t give up on its streetlights just yet.
