In 1988, Bernie Sanders outlined the key problem with news media today
"The function of private media is to make money for the people who own the media. It is a business," Sanders said.
- Over his four-decade political career, Senator Bernie Sanders has been an outspoken critic of mass news media.
- In a 1988 speech, Sanders described how it's virtually impossible to meaningfully discuss substantial political issues in 30-second sound bites, and how the consolidation of news outlets makes it harder for alternative views to reach the public.
- Surveys show that America's trust in mass media has been declining for years.
No matter your stance on the Vermont senator, it's hard to deny that Bernie Sanders has rightfully earned a reputation for not changing his politics over his four-decade career. In speeches and interviews, Sanders reliably returns to mantras about the one percent, voter turnout, and affordable healthcare and education, to name a few. These views have long been divisive, and it's up for debate whether his unwavering politics is indeed a virtue.
But one of Sanders' long-held views seems uniquely uncontroversial: that the structure of news media makes it hard, if not impossible, to discuss important political topics in a meaningful way. Speaking in 1988 at an event honoring the Vermont Vanguard, an independent newspaper, Sanders spoke about how hard it is to cram coherent ideas into TV-news soundbites.
"If you are a serious public official, how do you deal with the complex issues that your city faces or your state faces?" Sanders said. "And you look at that camera and you say, 'Oh god, I got 30 seconds to do it.' And then you understand why politicians become morons. It's not necessarily their fault. You try it sometime. Try to deal about a complex and serious issue, and get it into the 24 seconds that you need to get it into to get it onto the tube. It drives you a little bit crazy."
Echoing this idea in a 2019 interview with The Nation, Sanders said:
"This country faces enormous crises, and you can't do it in 45 seconds or a minute. That's just the simple reality. And I understand the problem of how many candidates are running. But we need a political structure in this country which allows serious debate about serious issues, and the structure of those debates makes it impossible I think for any candidate to do more than shout out a sound bite."
This "politics by soundbite" nature of TV news has changed not only the media, but also the way politicians think, Sanders said in 1988.
"You have politicians who then think in 30-second tidbits, which leads you to Ronald Reagan," he said. "The deep issues, the hard issues, are not as exciting as simplistic stuff."
Sanders' critiques of TV and corporate media extend further back than this speech. In a 1979 op-ed titled "Social Control and the Tube," Sanders said control of TV should be considered a political issue, and that public ownership would enable "serious writers" and "people with all kinds of views" to produce better work for the public.
"What the owners of the TV industry want to do, and are doing, in my opinion, is use that medium to intentionally brainwash people into submission and helplessness," Sanders wrote. "With considerable forethought they are attempting to create a nation of morons who will faithfully go out and buy this or that product, vote for this or that candidate, and faithfully work for their employers for as low a wage as possible."
Still, in his 1988 speech, Sanders said he doesn't support government control of the media, but that "corporate control over the media is equally dangerous, and that's very clearly the trend to which we're moving today."
Three decades later, Sanders said: "In 1983, the largest 50 corporations controlled 90 percent of the media. Today, as a result of massive mergers and takeovers, six corporations control 90 percent of what we see, hear, and read [...] These powerful corporations also have an agenda, and it would be naive not to believe that their views and needs impact coverage of issues important to them."
The consolidation of media companies was accelerated by changes to the Federal Communications Commission, with two major deregulatory shifts that occurred under Reagan and then Clinton, whose administration passed the 1996 Telecommunications Act. That law raised the cap on the number of local news stations and newspapers media corporations could buy.
Fewer Americans trust mass media
What also adds to the homogeneity of news media is shrinking revenues and a trend toward click-bait content. Big Think's Reuben Jackson recently noted:
"One effect of the contraction of the news industry is that journalists are networking with fewer peers and sources. In one recently published study, "Sharing Knowledge and 'Microbubbles': Epistemic Communities and Insularity in US Political Journalism," researchers from the University of Illinois explore the extent to which groupthink bias is increasingly being built into the content we consume."
These factors may help explain why Americans' trust in news media is declining. A 2020 Gallup survey found that six in 10 Americans have "not very much" trust (27 percent) or "none at all" (33 percent) trust in mass media. It's not a new trend: Gallup notes that trust in mass media hovered just above the majority level until 2005, and since it hasn't risen above 47 percent.

A Harvard professor's study discovers the worst year to be alive.
- Harvard professor Michael McCormick argues the worst year to be alive was 536 AD.
- The year was terrible due to cataclysmic eruptions that blocked out the sun and the spread of the plague.
- 536 ushered in the coldest decade in thousands of years and started a century of economic devastation.
The past year has been nothing but the worst in the lives of many people around the globe. A rampaging pandemic, dangerous political instability, weather catastrophes, and a profound change in lifestyle that most have never experienced or imagined.
But was it the worst year ever?
Nope. Not even close. In the eyes of the historian and archaeologist Michael McCormick, the absolute "worst year to be alive" was 536.
Why was 536 so bad? You could certainly argue that 1918, the last year of World War I when the Spanish Flu killed up to 100 million people around the world, was a terrible year by all accounts. 1349 could also be considered on this morbid list as the year when the Black Death wiped out half of Europe, with up to 20 million dead from the plague. Most of the years of World War II could probably lay claim to the "worst year" title as well. But 536 was in a category of its own, argues the historian.
It all began with an eruption...
According to McCormick, Professor of Medieval History at Harvard University, 536 was the precursor year to one of the worst periods of human history. It featured a volcanic eruption early in the year that took place in Iceland, as established by a study of a Swiss glacier carried out by McCormick and the glaciologist Paul Mayewski from the Climate Change Institute of The University of Maine (UM) in Orono.
The ash spewed out by the volcano likely led to a fog that brought an 18-month-long stretch of daytime darkness across Europe, the Middle East, and portions of Asia. As wrote the Byzantine historian Procopius, "For the sun gave forth its light without brightness, like the moon, during the whole year." He also recounted that it looked like the sun was always in eclipse.
Cassiodorus, a Roman politician of that time, wrote that the sun had a "bluish" color, the moon had no luster, and "seasons seem to be all jumbled up together." What's even creepier, he described, "We marvel to see no shadows of our bodies at noon."
...that led to famine...
The dark days also brought a period of coldness, with summer temperatures falling by 1.5° C. to 2.5° C. This started the coldest decade in the past 2300 years, reports Science, leading to the devastation of crops and worldwide hunger.
...and the fall of an empire
In 541, the bubonic plague added considerably to the world's misery. Spreading from the Roman port of Pelusium in Egypt, the so-called Plague of Justinian caused the deaths of up to one half of the population of the eastern Roman Empire. This, in turn, sped up its eventual collapse, writes McCormick.
Between the environmental cataclysms, with massive volcanic eruptions also in 540 and 547, and the devastation brought on by the plague, Europe was in for an economic downturn for nearly all of the next century, until 640 when silver mining gave it a boost.
Was that the worst time in history?
Of course, the absolute worst time in history depends on who you were and where you lived.
Native Americans can easily point to 1520, when smallpox, brought over by the Spanish, killed millions of indigenous people. By 1600, up to 90 percent of the population of the Americas (about 55 million people) was wiped out by various European pathogens.
Like all things, the grisly title of "worst year ever" comes down to historical perspective.
A new paper reveals that the Voyager 1 spacecraft detected a constant hum coming from outside our Solar System.
Voyager 1, humanity's most faraway spacecraft, has detected an unusual "hum" coming from outside our solar system. Fourteen billion miles away from Earth, the Voyager's instruments picked up a droning sound that may be caused by plasma (ionized gas) in the vast emptiness of interstellar space.
Launched in 1977, the Voyager 1 space probe — along with its twin Voyager 2 — has been traveling farther and farther into space for over 44 years. It has now breached the edge of our solar system, exiting the heliosphere, the bubble-like region of space influenced by the sun. Now, the spacecraft is moving through the "interstellar medium," where it recorded the peculiar sound.
Stella Koch Ocker, a doctoral student in astronomy at Cornell University, discovered the sound in the data from the Voyager's Plasma Wave System (PWS), which measures electron density. Ocker called the drone coming from plasma shock waves "very faint and monotone," likely due to the narrow bandwidth of its frequency.
While they think the persistent background hum may be coming from interstellar gas, the researchers don't yet know what exactly is causing it. It might be produced by "thermally excited plasma oscillations and quasi-thermal noise."
The new paper from Ocker and her colleagues at Cornell University and the University of Iowa, published in Nature Astronomy, also proposes that this is not the last we'll hear of the strange noise. The scientists write that "the emission's persistence suggests that Voyager 1 may be able to continue tracking the interstellar plasma density in the absence of shock-generated plasma oscillation events."

The researchers think the droning sound may hold clues to how interstellar space and the heliopause, which can be thought of as the solar's system border, may be affecting each other. When it first entered interstellar space, the PWS instrument reported disturbances in the gas caused by the sun. But in between such eruptions is where the researchers spotted the steady signature made by the near-vacuum.
Senior author James Cordes, a professor of astronomy at Cornell, compared the interstellar medium to "a quiet or gentle rain," adding that "in the case of a solar outburst, it's like detecting a lightning burst in a thunderstorm and then it's back to a gentle rain."
More data from Voyager over the next few years may hold crucial information to the origins of the hum. The findings are already remarkable considering the space probe is functioning on technology from the mid-1970s. The craft has about 70 kilobytes of computer memory. It also carries a Golden Record created by a committee chaired by the late Carl Sagan, who taught at Cornell University. The 12-inch gold-plated copper disk record is essentially a time capsule, meant to tell the story of Earthlings to extraterrestrials. It contains sounds and images that showcase the diversity of Earth's life and culture.
A team of scientists managed to install onto a smartphone a spectrometer that's capable of identifying specific molecules — with cheap parts you can buy online.
- Spectroscopy provides a non-invasive way to study the chemical composition of matter.
- These techniques analyze the unique ways light interacts with certain materials.
- If spectrometers become a common feature of smartphones, it could someday potentially allow anyone to identify pathogens, detect impurities in food, and verify the authenticity of valuable minerals.
The quality of smartphone cameras has increased exponentially over the past decade. Today's smartphone cameras can not only capture photos that rival those of stand-alone camera systems but also offer practical applications, like heart-rate measurement, foreign-text translation, and augmented reality.
What's the next major functionality of smartphone cameras? It could be the ability to identify chemicals, drugs, and biological molecules, according to a new study published in the Review of Scientific Instruments.
The study describes how a team of scientists at Texas A&M turned a common smartphone into a "pocket-sized" Raman and emission spectral detector by modifying it with just $50 worth of extra equipment. With the added hardware, the smartphone was able to identify chemicals in the field within minutes.
The technology could have a wide range of applications, including diagnosing certain diseases, detecting the presence of pathogens and dangerous chemicals, identifying impurities in food, and verifying the authenticity of valuable artwork and minerals.
Raman and fluorescence spectroscopy
Raman and fluorescence spectroscopies are techniques for discerning the chemical composition of materials. Both strategies exploit the fact that light interacts with certain types of matter in unique ways. But there are some differences between the two techniques.
As the name suggests, fluorescence spectroscopy measures the fluorescence — that is, the light emitted by a substance when it absorbs light or other electromagnetic radiation — of a given material. It works by shining light on a material, which excites the electrons within the molecules of the material. The electrons then emit fluorescent light toward a filter that measures fluorescence.
The particular spectra of fluorescent light that's emitted can help scientists detect small concentrations of particular types of biological molecules within a material. But some biomolecules, such as RNA and DNA, don't emit fluorescent light, or they only do so at extremely low levels. That's where Raman spectroscopy comes into play.
Raman spectroscopy involves shooting a laser at a sample and observing how the light scatters. When light hits molecules, the atoms within the molecules vibrate and photons get scattered. Most of the scattered light is of the same wavelength and color as the original light, so it provides no information. But a tiny fraction of the light gets scattered differently; that is, the wavelength and color are different. Known as Raman scattering, this is extremely useful because it provides highly precise information about the chemical composition of the molecule. In other words, all molecules have a unique Raman "fingerprint."
Creating an affordable, pocket-sized spectrometer
To build the spectrometer, the researchers connected a smartphone to a laser and a series of plastic lenses. The smartphone camera was placed facing a transmission diffraction grating, which splits incoming light into its constituent wavelengths and colors. After a laser is fired into a sample, the scattered light is diffracted through this grating, and the smartphone camera analyzes the light on the other side.

To test the spectrometer, the researchers analyzed a range of sample materials, including carrots and bacteria. The laser used in the spectrometer emits a wavelength that's readily absorbed by the pigments in carrots and bacteria, which is why these materials were chosen.
The results showed that the smartphone spectrometer was able to correctly identify the materials, but it wasn't quite as effective as the best commercially available Raman spectrometers. The researchers noted that their system might be improved by using specific High Dynamic Range (HDR) smartphone camera applications.
Ultimately, the study highlights how improving the fundamentals of a technology, like smartphone cameras, can lead to a surprisingly wide range of useful applications.
"This inexpensive yet accurate recording pocket Raman system has the potential of being an integral part of ubiquitous cell phones that will make it possible to identify chemical impurities and pathogens, in situ within minutes," the researchers concluded.
