Tribal STEM...



Salish Kootenai College (SKC) is a four-year college located on the Flathead Indian Reservation in western Montana. It is one of 32 fully-accredited US colleges and universities in which at least 51% of students are enrolled in federally recognized tribes.



The US Department of Education classifies these higher education institutions as TCUs (tribal colleges and universities). Most of the TCUs are chartered and controlled by tribal governments. Three are controlled by the US Bureau of Indian Affairs. The Confederated Salish and Kootenai Tribes govern SKC.



The first TCUs were established in the late 1960s and early 1970s, and initially these institutions focused on vocational education programs. Although vocational training remains an important part of their mission, TCUs also offer a growing number of two- and four-year science, technology, engineering, and mathematics (STEM) degrees.



SKC awarded its first four-year STEM degree, in environmental science, in 1997. Since then, SKC has added baccalaureate programs in computer engineering, forestry, hydrology, information technology, life science, and secondary science education. The programs aim to provide additional career opportunities, and to promote long-term economic development of reservation communities. Today's STEM graduates will be tomorrow's entrepreneurs who provide economic opportunities for tribal members. Economically-strong tribal communities help preserve the cultures, languages, histories, and natural environment of their constituents.




In many ways, SKU's programs mirror the curricula one finds at non-TCUs. But they also incorporate traditional indigenous knowledge of the natural world and pedagogical approaches that reflect tribal cultural norms. They emphasize a teamwork approach, and they focus on strategies to improve quality of life and preserve natural environments. SKC STEM faculty members generally view traditional indigenous worldviews to be complementary to, rather than in conflict with, Western science.

The Science of Beatboxing...


As a young man, exposed to the first rap song - The Fatback Band: King Tim III - Personality Jock, and the first rap album, The Sugar Hill Gang (all in the same crazy week, mind you) - I could never do it, but it's nice to see someone has actually studied it.

However, as evidenced from the Large Hadron Collider rap... ahem, the physicists would need a few more decades of practice to master it (my humble opinion).

Many of the same mechanisms observed in human speech production were exploited for musical effect, including patterns of articulation that do not occur in the phonologies of the artist's native languages: ejectives, clicks and implosives.

The scientists found the beatboxer, a speaker of American English and Panamanian Spanish, was able to generate a wide range of sound effects that do not appear in either of the languages he spoke. Instead, they appeared similar to clicks seen in African languages such as Xhosa from South Africa, Khoekhoe from Botswana, and !Xóõ from Namibia, as well as ejective consonants — bursts of air generated by closing the vocal cords — seen in Nuxálk from British Columbia, Chechen from Chechnya and Hausa from Nigeria and other countries in Africa.

 

"A key finding of our work is to show that we can describe the basic sounds used by the artist with the same system used to describe speech sounds, which suggests that there is a common inventory of sounds that are drawn upon to create any vocal expression," Proctor said.

 

The research also sheds light on the human ability to emulate sounds, and on how the human instincts for music and language can overlap and converge. Also, "learning more about beatboxing and other forms of vocal musical expression may offer insights into novel future speech therapy," Narayanan said.

Mandela, Man of Mission

  I paused to praise a man in the twilight of life.  One brave enough to fight for his brethren, sacrifice 27 years of his life in a small dingy cell on an island that seems a lifetime away from everything one loves, and one who rose to exultation in 1994 to become president of the very people he was shackled for defending.  AMANDLA! 
     Mandela, there are few like you past and present, that have ever walked the earth.  A man who could stare down fear and hate, and survive!  There are no words that could truly do you justice.  As you prepare to leave this place, as you prepare to lock in the embrace of the heavens and continue your great work in the Angelic realms, just know that I, that we, are grateful that you walked amongst us.  I would like to thank your children, your wives, and your close friends, for their hardships and sacrifices as well.  I would like to thank them for lending you to us, for supporting you, and helping you to become the hero that you are.
     Mandela, my eyes widened with wonder when you were released from prison on February 11, 1990.  I sat on the chest in my grandmothers room and asked, "Who is this man?  Why is everyone sooo happy?" I was seven years old.  Henceforth, I read all of the articles and watched all of the news reports about the horrors of apartheid and your hero's journey.  20 years later, I had the opportunity to visit South Africa, to understand what Hell apartheid was, to see the ineffable poverty, and  to bear witness to the journey of healing that South Africa still must travel.  Again, to what you have given, there are truly no words.
     Mandela, you are about to join Malcolm X, Martin Luther King, Marcus Garvey, Medgar Evers, and so many other freedom fighters, my God, what good company you are in!  I cannot wait to see what amazing work you do from the heavens!  I'm just glad that I was able to see your amazing work in my lifetime.  Thank you Nelson Rolihlahla Mandela, you are appreciated. AMANDLA!

Outsmarting Heisenberg...



Laser interferometers detect tiny distance changes with high precision. Stray light reduces and limits the measurement accuracy of these instruments. Researchers at the Albert Einstein Institute in Hannover have now shown for the first time how to discriminate between measurement signal and stray light using lasers with tailored quantum properties. The novel measurement concept circumvents the Heisenberg uncertainty principle and could enhance the precision of gravitational-wave detectors like GEO600 or the closely cooperating Advanced LIGO (aLIGO) detectors in the USA.

 

The scientists at the Albert Einstein Institute (AEI; Institute for Gravitational Physics at Leibniz Universität Hannover and Max Planck Institute for Gravitational Physics) in Hannover are hunting for elusive gravitational waves—a prediction from Einstein's general theory of relativity. Their first direction detection will open a new window to our Universe and usher in the era of gravitational-wave astronomy. The AEI researchers aim to detect these tiny space-time ripples using detectors like GEO600 near Hannover, Germany, and aLIGO in the U.S. These detectors use lasers to measure the tiny distance changes caused by passing gravitational waves. Thus, the continuous improvement of those lasers and the minimization of disturbances like stray laser light is of great importance.

 

R&D Mag: Outsmarting Heisenberg

Hello again!  I know it's been a little while since I've blogged, but after getting in a few online scrapes, I felt I just had to clear things up for future reference.  I've found that most people, Christian or otherwise, really do have this candy-coated picture of what Christian mercy and forgiveness is supposed to be.  They're under the peculiar impression that the Biblical definition of mercy and forgiveness is "anything goes".  I will agree that Jesus Christ does want all Christians to be forgiving and He desires us to be merciful.  What's been lost is the context in which this was said. 
Let's begin with God, also known as Jehovah, the God of the Covenant that was established in the book of Leviticus (which is also in the Bible).  Christians are supposed to worship Jesus Christ because we believe that He is the son of Jehovah, the God of the Covenant.  In this Covenant, rules are laid down as to what Jews, Christians, and even some Muslims, should and should not do.  Leviticus is quite simply "The Law" as far as Judeo-Christian religions are concerned.  Now when the Law was written it also established the punishment that was required for each infraction.  Feel free to read it on your own, but in the meantime,  here's an abstraction:
If you committed adultery, you were killed.
If you had sex with an animal, you were killed.
If you were gay, you were killed.
If you were a woman that kicked a man in the nuts, you were killed.
If you raped a woman, you had to marry her.  If you didn't, you were killed.
You're probably starting to notice a theme here.  Don't worry.  If you were found guilty of theft, you only had to repay the value of what you stole seven times over.  However, if you were caught in a person's home stealing, there was a good chance you'd be killed.  Also...
If your child was a hellion no one could control, he/she was killed. 
If you went to worship while on your menstrual cycle, you were killed.
It is worth noting that if you beat your meat (masturbated), you were not killed.  You were merely considered unclean and could not participate in any holy ceremony until you had bathed and waited until evening.  However, if you went to worship without doing this,  you were killed.  
Now this is The Law.  This is what Christians are talking about usually when they say that the Bible forbids something.  Have you ever heard the saying, "The wages of Sin are Death"?  That's not a metaphor.  The Bible is filled with metaphors, I'll admit, and there's a bit of "spiritual death" in the book, but, more often than not, Biblical characters (including Jesus) took that saying VERY literally.  Also that verse about "Thou shalt not kill" was a mistranslation if you didn't get the memo.  The correct translation is "Thou shalt not murder".  The difference?  Killing is the ending of a life, any life, human or otherwise.  Murder is usually defined as a human specifically that kills another human being that has not wronged them or committed an immoral act.  In practice?  You can kill bugs, but not children, unless the community has deemed the child an uncontrollable hellion. 
Now The Law did have some escape clauses in it.  Certain crimes could be forgiven with the sacrifice of a certain animal.  If you did this correctly, you would be FORGIVEN (not killed).  Of course, if you sacrificed the animal after having terrific sex with your wife that morning, well, you would be... deprived of your breathing privileges.  This is what FORGIVENESS means in the Bible: a lighter sentence than what the Law would prescribe, i.e. you weren't killed.  This is the Law that Jehovah, the God of the Covenant, gave to us.  So if you cheat on your Christian wife and she slashes your tires, she is being FORGIVING because according to The Law, she can get her brothers to kill you and be well within her rights.  I reiterate, having your cheating spouse killed, according to Levitical Law, is not a sin.  It's illegal.  It's unmerciful.  It's unforgiving, but not immoral.
This is Christian forgiveness.  Then again, you probably think that Christians should be more God-like in how they forgive.  Well, let's take a look at how the Judeo-Christian God forgives.  The character of David in the Bible is one of the most important as he is considered to be God's favorite, second only to Jesus Christ Himself.  However, David, like all humans, sinned against God.    He had a man killed so that he could sleep with the man's wife.  The Law specifically says not to lust after another man's wife.  Would you like to take a wild guess as to what David's punishment should have been?  But NO!  David begged, prayed, and pleaded with God for His Forgiveness.  Then God, in His Great Mercy, forgave David.  He gave David a lighter sentence.  The sentence?  His next baby would be killed and "evil" would rise against David from his own house.  What kind of evil, you ask?  His daughter was raped by her brother.  That brother was killed by another brother, then that brother tried to kill David.  This was David's punishment AFTER he was forgiven.  Dead sons and raped family. 
Remember this when you chastise another Christian for not showing, what you believe to be, God's Forgiveness.  David was not killed for his transgression.  His children were.  Oh, and a couple of his wives were raped too.  FORGIVENESS is such a beautiful thing, isn't it?  Now I've said and done some harsh things to people who have wronged me, but, yes, I do walk around with a very clear conscience.  Why?  Because I showed mercy and forgiveness.  I didn't kill any of the offenders (although the thought did cross my mind) and I didn't rape or slaughter their children.  Thus I have forgiven my offenders and shown them mercy.  Their refusal of my non-murderous and non-sexually-aggressive harshness I simply see as an act of ingratitude. 
Oh, but still, some of you believe that Christians should focus less on the Old Testament and more on the New Testament because the New Testament has Jesus Christ in it.  Ah, Jesus Christ!  The greatest person in history!  What a wonderful man!  He's here to save the day!  Here it comes:
"He who is without sin cast the first stone"
BAM!  POW!  ZING!  That metaphor has destroyed my whole argument.   But wait...  You've forgotten the context again.  Jesus Christ wasn't being metaphorical.  He was talking to a crowd of people intent on throwing actual stones.  Thus Christian forgiveness is still centered around giving lighter sentences than what The Law prescribes.  The crime here?  Adultery.  Hmm...what's the sentence for adultery again?  Oh yeah!  Death.  The person being stoned was a woman, which the scripture explicitly states, was caught in the act of adultery.  Jesus prevented her from being killed for this crime.  He also told her not to sin again, i.e., screw the same guy they caught her screwing before.  This is another part of Christian forgiveness: the cessation of the offense.  Jesus Christ doesn't want us to kill people for their sins, but he would like for those people to stop sinning. 
Now you're probably still grinning about the non-murderous Messiah and you're planning on berating some more Christians that take you to task for your lifestyle since they're not being the pacifist punk you believe our Savior to be.  Well...I'll try to make this brief:
This is how Jesus Christ would speak to the Pharisees, the people who were constantly trying to trick, deceive, and destroy Jesus, a.k.a. his "haters". 
"But when he saw many of the Pharisees and Sadducees coming to where he was baptizing, he said to them: "You brood of vipers! Who warned you to flee from the coming wrath?"  (Matthew 3:7 NIV)
"You snakes! You brood of vipers! How will you escape being condemned to hell?"  (Matthew 23:33 NIV)
"Woe to you, teachers of the law and Pharisees, you hypocrites!"  (Matthew 23: 23, 25, 27 & 29 NIV)
Oh, and that last notation isn't a mistake.  Jesus Christ repeated that exact same line four times in the same chapter.  Then there was that incident with the money changers in the temple:
"Jesus entered the temple courts and drove out all who were buying and selling there. He overturned the tables of the money changers and the benches of those selling doves."  (Matthew 21:12 NIV)
Then there was the Syro-Phoenician woman:
"She begged Jesus to drive the demon out of her daughter.
'First let the children eat all they want,' he told her, 'for it is not right to take the children’s bread and toss it to the dogs.'
'Lord,' she replied, 'even the dogs under the table eat the children’s crumbs.'
Then he told her, 'For such a reply, you may go; the demon has left your daughter.' "
For those of you who missed that, yes, that passage contains a woman begging for her child to be healed and Jesus not wanting to because the woman is not Jewish, or even Samaritan (Samaritans used a different Torah).  Yes, Jesus Christ, a Jew, had a strong preference for other Jews.  The original twelve Apostles?  All Jewish.  Today, we would call that racism.  I just call it good Christian fun.  With that being said, what were you telling other Christians about tolerance again? 
Well, let me tell you how Jesus actually treated people.  He would call you names and insult you if He didn't like you or were "proud" of the sin you were committing.  If you brought your mess into a church, he would knock over your tables and tell you to leave.  And when you finally came to Him asking for FORGIVENESS and mercy, His race would get preferential treatment, although he wouldn't reject you outright. 

But...

Jesus didn't kill anyone and he didn't rape or murder any children.  Why?  Because He was FORGIVING.  Now you actually know what you're asking Christians when you tell them to have Christian forgiveness.  You're simply telling us not to kill you or rape your children.  I mean, we're Christians.  We kill people, and much like the ancient Hebrews we strive to emulate, we've been killing people for a very long time.  We follow a more forgiving Deity in that He preferred to insult people rather than butcher them, but if you're looking for quiet pacifists, go dig up Gandhi or call the Dalai Lama.  Do not ask Christians for forgiveness or mercy because if you're still alive and your children are living and un-raped (in the  literal sense), then you have already received it.

Okay, the Supreme Court, with five conservative white men (we’ll argue about that later, I’m sure), displaying the fear conservative whites have over losing their racial majority and traditional white privilege in these United States of America, has rolled back one of the few protections non-whites in traditionally racist states have against complete political irrelevance.

The political ramifications aside, let us imagine today’s America degenerating into a 1850s social, economic, political and cultural landscape.

Let’s imagine women no longer able to vote, and once again the property of men, unable to own property on their own.

Let’s imagine Black men relegated to slave status, also not having the ability to vote and to only be counted as 3/5ths of a man in the census.

Let’s imagine Black women as little better than sex slaves and the subjects of breeding experiments to try to produce that “perfect” slave; big, stupid and compliant.

Let’s imagine Blacks unable to own property or to be allowed to have or control their own money.

Let’s re-imagine those Blacks who will curry favor from the white masters in order to eat in the big house, wear better clothes, and most importantly, lord their status over the rest.

This trend in conservative strategy just begs for a look at just how America would turn out today with early 1800s', Paula Dean type sensibilities...

Novella anyone?

This was unveiled at the Paris Air Show as "radical and unpractical." Possibly why EADS is giving itself until 2050 to bring it to fruition. Superconductivity seems to be a part of the design - currently only used on Maglev Trains in Japan and Shanghai - some considerable technological advances are required to make such a hybrid mostly electric/minimized fuel engine.

About Your Region

Your ethnicity indicates that you have ancestry from West Africa, an area that stretches along the continent's Atlantic coast from the desolate sands of the Sahara in Mauritania and Mali to the humid canopies of the central African rain forests in Gabon and Congo. Camel caravans once hauled rock salt from desert mines through the legendary city of Timbuktu. And it's the only place on Earth where you can see a lowland gorilla outside of a zoo.

The people of this region trace their ethnic and cultural roots to numerous different sources. The Tuareg Berbers in the predominantly Muslim north are descended from the desert nomads of the Sahara; the sub-Saharan African populations including the Hausa, Mandinka, and Youruba are descendents of the ancient western kingdoms that dominated the region before the arrival of European colonists; the Baka of Cameroon and Gabon, previously referred to as "pygmies," are some of the oldest residents of the area; and the Bantu language group, which originated in Cameroon, is spoken across the entire southern half of the continent.

European colonialism and exploitation, including a centuries-long slave trade, as well as brutal civil wars, despotism, and uncontrolled governmental corruption in the post-colonial era have kept the region mired in poverty. Since the end of Liberia's second civil war in 2003, the region has seen a stretch of relative peace and a decrease in corruption. Hopefully the future will bring prosperity to this region.

Migrations into this region

Western Africa was first occupied by modern humans about 50,000 years ago. More recently, the colonial period saw immigrants from many European countries establish colonies and trading posts throughout Western Africa. However, the genetic impact of these historical Europeans is thought to be very small.

Migrations from this region

The majority of African-Americans ancestry derives from Western Africa. This is mostly because during the Atlantic slave trade of the 18th and 19th centuries, African slaves from the coastal regions of Western Africa were captured and shipped to the Americas. Even groups further inland were sometimes captured and traded out to the coast for slavery.

 From the start I face palmed my entire time seeing the trailer for once again while White audiences are given Superman and Thor, Black audiences are graced with yet another Black maid/servant movie. Now don't get me wrong the movie seems to have a solid cast and I would give anything to bet one of the Black cast members will be rewarded with an Oscar for being a maid or butler. While watching the movies trailer on YouTube I couldn't help but to look at the comments to see what others were saying about the film and one comment posted was that stories like these need to be told. While I agree to a certain extent I still beg the question how long will this story be told? Is this the only story Black Americans have to tell? Are moving stories from the Black mind only about being some "dignified" Black servant for White America?

 The character of the Black servant be it historical or fictional has been a character that Hollywood has had no problem marketing. From Gone with the Wind in 1939 to The Help in 2011 to The Butler in 2013 the character of the black servant is slowly being reintroduced in modern society. All these films seem to tell the movie going audiences that no matter how bad Black servants where treated during these time periods Black maids and butlers didn't care and saw some type of dignity in what they are doing. On top of that you throw in a few "Good" White people to let both white and black audiences know that not all Whites were bad doing this time. To many times we get into the habit of believing these stories are true simply because there was a time when these things did happen and that somehow these films are good to the black mind to see what we know to be untrue to suddenly become true because "good" white people are behind it.

When it comes to historical movies about African-Americans the only movies that are successful are Black servants films but movies depicting African-Americans as heroes like in Red Tails or a messiah type character like in Malcolm X seem doomed to fail. Why? Because it is my opinion that Black people have been conditioned only to see themselves in a certain way. White audiences are given the images of themselves as Superman, Iron man, and Thor but Black audiences are given Precious and The Help and I believe that there is a reason for this. How many movies have been made on Abraham Lincoln? How many World War 2 films have been made? How many American western films are made? My point in saying this is these films are Historical films yet they all showing different sides of White American history. When it comes to Black American history or The World history of Black people we are only given one side of the story as if our history begins and ends in a state of servitude. Where are the epic films on the Nubian Pharaohs of Africa? We seem to have hundreds on the "great" accomplishments of the Greeks and Romans!

  Films like The Butler may be true stories and may move hearts, but I believe those are stories that white audiences are comfortable seeing and Black audiences are conditioned to accept. Anything beyond that territory will ultimately begin to wake up the hearts and minds of black people.

Genie Out of the Bottle...



Given his calm and reasoned academic demeanor, it is easy to miss just how provocative Erik Brynjolfsson’s contention really is. ­Brynjolfsson, a professor at the MIT Sloan School of Management, and his collaborator and coauthor Andrew McAfee have been arguing for the last year and a half that impressive advances in computer technology—from improved industrial robotics to automated translation services—are largely behind the sluggish employment growth of the last 10 to 15 years. Even more ominous for workers, the MIT academics foresee dismal prospects for many types of jobs as these powerful new technologies are increasingly adopted not only in manufacturing, clerical, and retail work but in professions such as law, financial services, education, and medicine.

That robots, automation, and software can replace people might seem obvious to anyone who’s worked in automotive manufacturing or as a travel agent. But Brynjolfsson and McAfee’s claim is more troubling and controversial. They believe that rapid technological change has been destroying jobs faster than it is creating them, contributing to the stagnation of median income and the growth of inequality in the United States. And, they suspect, something similar is happening in other technologically advanced countries.

I talked about this here, here, here and here. Wrote a book about it (literally).

We're given ourselves self-serving mythologies of "shining cities on a hill"; "chosen nation"; pursue multiple choice exams over education, creationism/intelligent design and other made-up "controversies"; junk science in the halls of congress, #scamdals, chimeras and "created realities" because pursuit of poltergeists allow pols not to do their actual elected jobs of managing the commonwealth for the common good (i.e. redistricting = Zombie government).

Our technology is literally superseding our need for certain workers.

For example, when some of us just "couldn't do college" a generation ago, Americans could get a job in a factory - I'll use the automotive industry - and build a decent middle-class life for themselves and a family. A blue collar job might have been to use a drill on an assembly line for lug nuts, bolts, etc. Now, that's done by a robot that doesn't call in sick; doesn't need vacation; won't demand a retirement. Most hiring by US firms is abroad where pay is lower than our national minimum wage. The other good option was the military - recall it was a "peacetime force" post Vietnam.

I am not advocating slowing down, "crawling in a cave"; running for the hills. The genie is out of the bottle now, and we're debating (if you want to call it that) problems that have no impact. Period.

Our sense of the "American Dream" is changing daily, as should our definition of middle class, upper class and financial plasticity - the ability to move freely from class-to-class (hopefully upward). We've got the most expensive health care on the planet, and I've had two good friends - one my fraternity line brother - perish due to lack thereof: insurance is an expensive business with real casualties. Our living longer puts stress on geriatrics, resources and food supplies. Weather, whether you want to call it climate change or a rather heated solar cycle, is now part of what is briefed in the actual Situation Room. We either accept these realities, and prepare our children academically and morally for them: or, inherit the whirlwind of societal instability. This is Sky-net in slow-mo, and "The Hunger Games"; "Brave New World"  nor "1984" should not be a blueprint for our collective futures.

What Orwell feared were those who would ban books. What Huxley feared was that there would be no reason to ban a book, for there would be no one who wanted to read one. Orwell feared those who would deprive us of information. Huxley feared those who would give us so much that we would be reduced to passivity and egotism. Orwell feared that the truth would be concealed from us. Huxley feared the truth would be drowned in a sea of irrelevance. Orwell feared we would become a captive culture. Huxley feared we would become a trivial culture, preoccupied with some equivalent of the feelies, the orgy porgy, and the centrifugal bumblepuppy. As Huxley remarked in Brave New World Revisited, the civil libertarians and rationalists who are ever on the alert to oppose tyranny "failed to take into account man's almost infinite appetite for distractions". In 1984, Huxley added, people are controlled by inflicting pain. In Brave New World, they are controlled by inflicting pleasure. In short, Orwell feared that what we hate will ruin us. Huxley feared that what we love will ruin us.

This book is about the possibility that Huxley, not Orwell, was right.

Dropping Science...


Marks the 1,215th post (also, my childhood street address).

 

Don't panic: I know school's out for summer...and that's the chant from the teachers!Smiley

 

This is something I've thought about. In the seventies we had School House Rock (you better believe I have this DVD). A lot of great memories: multiplication, science, grammar, government and how it should work. As a teacher, I recall having to compete with the district demands of test prep, video game systems, mobile devices and the latest script-and-drama from reality TV. Rock was the innovation of its day, a way to engage us in passive learning. I can still sign most of the songs and recall things from its lessons (what I don't remember, I can now review in my living room).

 

This is just another means to engage kids in science, something as a nation we still need to do...

 

As part of a program created by Columbia professor Christopher Emdin, 10 New York City high school classes have been writing raps as a way to learn about science. The program is called Science Genius, and it sounds like the sort of patronizing pop-culture hijack kids hate more than anything. But when Wu-Tang’s GZA drops by a Bronx classroom to discuss the importance of scientific inquiry, you can see the actual moment when the students realize the program is legit.

The Smallest Battery...


Saw this on my FB feed from "I f#&$ing love science." This is REALLY fantastic...

A research team from Harvard University and the University of Illinois at Urbana-Champaign has demonstrated the ability to 3D print a battery. This image shows the interlaced stack of electrodes that were printed layer by layer to create the working anode and cathode of a microbattery. (SEM image courtesy of Jennifer A. Lewis.)


Cambridge, Mass. – June 18, 2013 – 3D printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on lab benches for lack of a battery small enough to fit the device, yet provide enough stored energy to power them.

 

To make the microbatteries, a team based at Harvard University and the University of Illinois at Urbana-Champaign printed precisely interlaced stacks of tiny battery electrodes, each less than the width of a human hair.

 

“Not only did we demonstrate for the first time that we can 3D-print a battery; we demonstrated it in the most rigorous way,” said Jennifer A. Lewis, senior author of the study, who is also the Hansjörg Wyss Professor of Biologically Inspired Engineering at the Harvard School of Engineering and Applied Sciences (SEAS), and a Core Faculty Member of the Wyss Institute for Biologically Inspired Engineering at Harvard University. Lewis led the project in her prior position at the University of Illinois at Urbana-Champaign, in collaboration with co-author Shen Dillon, an Assistant Professor of Materials Science and Engineering there.

 

The results have been published online in the journal Advanced Materials.

By Chaz Ebert, wife of the Late Roger Ebert

Roger was writing reviews right until the very end. One day in the hospital I suggested that he take a break from work-related writing and write something creative that made him feel like he did when he was writing science fiction articles for fanzines when he was a boy. He began writing "The Thinking Molecules of Titan", a story about space exploration set in part at his beloved University of Illinois. 

He never got a chance to finish it.  

In the spirit of Roger's belief in crowd participation, we're having a contest to help complete the story.

Write your own ending and email it to us at contests@ebertdigital.com, with the subject header "TITAN ENDING", followed by your FULL NAME. 

We'll gather the submissions and narrow it down to a select group of finalists, solicit your votes on which is the best, and announce the winner on the site. -- Chaz

Breaking the Gigahertz Barrier...


Researchers in the US and Italy have made the first integrated graphene digital circuits that function at gigahertz frequencies. The circuits are ring oscillators and the work could be an important step towards realizing all-graphene microwave circuits, says the team.



Graphene is a 2D sheet of carbon just one atom thick and it – along with similar 2D materials such as carbon nanotubes and molybdenite – shows great promise for future electronics. This is because electronic devices smaller than 10 nm could be made using these 2D materials – at least in principle. Below the 10 nm length scale, devices based on conventional silicon are expected to be too small to function properly and therefore graphene and similar materials offer a route to making ever-smaller electronic devices.

One major challenge facing those developing such 2D devices is speed. Modern silicon processors operate at microwave (gigahertz) frequencies, as do communications chips in devices such as mobile phones. Therefore, any practical 2D device would have to run just as fast. Until now, however, the fastest 2D device – a carbon-nanotube ring oscillator – operates at a lethargic 50 MHz.

Now, a team led by Roman Sordan of the Politecnico di Milano and Eric Pop of the University of Illinois says it has made the first integrated graphene oscillators – with the added bonus that the devices operate at 1.28 GHz. The graphene ring oscillators also appear to be less sensitive to fluctuations in the supply voltage compared with both conventional silicon CMOS devices and earlier oscillators made from the 2D materials.

Growing Your Phototransistor...



TECHNOLOGY REVIEW: Chlorophyll is one of the most efficient light-absorbing materials known to science. It also happens to be remarkably stable and abundant beyond imagination.


Researchers studying ways to capture and exploit photons view the amazing capabilities of chlorophyll with green-eyed wonder. Indeed, they would dearly love to copy this extraordinary light-gathering ability.

But there may be a quick way of catching up. Instead of designing and making artificial materials that attempt to copy chlorophyll, researchers have begun to think about using this naturally-occurring material itself and attempting to bend it to their will.

Today, Shao-Yu Chen at the Institute of Atomic and Molecular Sciences in Taiwan and a few buddies reveal how they have incorporated chlorophyll into graphene transistors to make light-activated switches.

The new phototransistor design is relatively simple. It consists of two silver electrodes connected by a sheet of graphene. The graphene is then covered by a layer of chlorophyll using a method known as drop casting. This involves placing a drop of liquid containing chlorophyll on top of the graphene and letting it evaporate. This coats the graphene with a layer of chlorophyll.

I just got a message from someone who thinks that I should change the page name from "Black" to "African Heritage".

She feels that everyone else is identified by their ethnicity, but that page is identified by color and so she doesn't feel comfortable recommending the website to children and young people because she doesn't feel that the label is suitable.

One of the reasons I have "Black" is that not all those who are called "Black" are African or of (recent) African heritage. The indigenous people of Australia are considered Black, as are the native peoples of the Philippines.

Also, honestly, I am U.S. based and Black is how most of my brothers and sisters refer to themselves.

Please be super honest with me. If you need to rip a hole because I'm wrong, wrong, wrong, then please do tell me. I'm a big girl, I can handle it.

Thanks so much, Ruth

Context

When looking at this picture I was initially amazed, since I believed it to be something that it is not.

What it is, is a group of businessmen looking at the hull of a larger early 20th century cruise liner. Possibly the Titanic, but it could be anything from the Lusitania to some unknown ship that was sunk during the Battle of the Atlantic.

However, what it looked to me at first glance, was the undercarriage of a great Airship. These gentlemen, these Aeronauts, were proudly embarking on a circumnavigation of the globe in their floating dreadnought. Armed with wits and guns and inevitable communicable diseases, they would venture into the dense jungles of Amazonia . On their journeys, they would encounter the fabled lost cities described by defrocked Jesuit Francisco DeOriana, fight dangerous Air-Pirates and commit wanton acts of Derring-Do.

Of course, none of this happened, but it is an important lesson for any story teller or historian. Context matters. Context told me I was looking at the ribs of a giant inflatable balloon, not the walkways to a ship deck.

Context matters to story tellers because we can slant stories in a certain way. Make certain people the heroes or the villains, depending on the context, depending on the point of view.

In fiction, it used to be that POCs were typically the enemy, or if not worthy of fear, then contempt.

(See Armageddon 2419AD for a pretty racist view of both Asians and Africans)

POC and depictions of them have changed in the 80 years since 2419 published. Partly that is because of context. Consumers and their tastes have changed. While POC have not achieved parity in terms of "hero" status, actors such as Will Smith and Vin Diesel have proven that there is a commercial market for a POC as the heroic lead.  In order to see greater representation in both interactive and static entertainment, authors have to continue to shift the context.

However, context shifting has to be more than preaching to some POC choir. It has to involve moving the context of what a hero does, what he or she looks like, and what is the nature of heroism. If you are fighting on someone else's ground, you will always be seen in their context.

It would like to say that we at MM are doing that, but the honest truth is that we haven't done it well enough.
