Are There Bacteria In Your Brain?
The brain is protected from the bacterial menagerie of the body by the blood-brain barrier, and is considered a sterile organ. Which made it all the more surprising when Rosalinda Roberts, along with Charlene Farmer and Courtney Walker, realized that the unknown objects in their slides were bacteria.
The Citizen Scientist Who Finds Killers From Her Couch
CeCe Moore has no scientific degree. Like other prominent figures in the genealogy community, she is self-taught. Moore is, in her own estimation, among the most experienced genetic genealogists in the world. Now she is using her genetic knowledge to expose murderers.
Data Compression Drives the Internet. Here’s How It Works.
With more than 9 billion gigabytes of information traveling the internet every day, researchers are constantly looking for new ways to compress data into smaller packages. Cutting-edge techniques focus on lossy approaches, which achieve compression by intentionally “losing” information from a transmission.
We’re Getting Closer To The Quantum Internet, But What Is It?
Instead of the bits that today’s network uses, which can only express a value of either 0 or 1, the future quantum internet would utilize qubits of quantum information, which can take on an infinite number of values. A quibit is the unit of information for a quantum computer; it’s like a bit in an ordinary computer.
The True Toll Of The Chernobyl Disaster
On 26 April 1986 reactor number four at the power plant suffered a catastrophic explosion that exposed the core and threw clouds of radioactive material over the surrounding. Covered up by a secretive Soviet Union at the time, the true number of deaths and illnesses caused by the nuclear accident are only now becoming clear.
Scientists Create Enzyme That Breaks Down Plastic To Raw Materials
French scientists have discovered a mutant bacterial enzyme that can break down plastic for recycling within hours. The plastic-eating enzyme could offer an innovative recycling solution for millions of tonnes of toxic plastic waste material.
The Diabetes Patients Who Hacked A Pancreas
While diabetics anxiously awaited the release of commercial systems, tech-savvy diabetics and their loved ones worked on do-it-yourself systems. How could a bunch of hackers, working in their free time, create something medical manufacturing companies had yet to put on the market?
What Facial Recognition Steals From Us
In just the past five years, the meaning of the human face has quietly but seismically shifted. That’s because researchers at Facebook, Google, and other institutions have nearly perfected techniques for automated facial recognition.
‘Astounding New Finds’ Suggest Ancient Empire May Be Hiding In Plain Sight
Evidence from Maya writing and art suggests Teotihuacan conquered Tikal outright, adding it to what some archaeologists see as a sweeping empire that may have included several Maya cities. Teotihuacan may have turned against Maya expatriates who had lived there peacefully for decades.
How Political Opinions Change
A powerful shaping factor about our social and political worlds is how they are structured by group belonging and identities. For instance, researchers have found that moral and emotion messages on contentious political topics, such as gun-control and climate change, spread more rapidly within rather than between ideologically like-minded networks.
Inside SpinLaunch, The Space Industry’s Best Kept Secret
Last summer, a secretive space company took up residence in a massive warehouse in the sun-soaked industrial neighborhood that surrounds Long Beach Airport. The company is building a massive centrifuge to accelerate rockets and send them screaming into space.
When Gravity Breaks Down
Albert Einstein’s theory of general relativity is more than a hundred years old, but still it gives physicists headaches. Not only are Einstein’s equations hideously difficult to solve, they also clash with physicists’ other most-cherished achievement, quantum theory.
How One NASA Image Tells Dozens Of Stories
In 2016, NASA used the Suomi NPP weather satellite to create a high resolution image of the earth at night. It can help us better understand the current developments and conflicts underway. The amount of light pollution is most severe in heavily populated areas, as well as in regions of high prosperity.
What Fruits And Vegetables Looked Like Before Humans Intervened
The fruits and vegetables we know and love are a lot more complicated than you’d think. They didn’t always look like they do. In fact, it took decades of human intervention to transform them into the delicious, nutrient-rich morsels they are today.
Peter Hotez Vs. Measles And The Anti-Vaccination Movement
Texas is at risk of a deadly measles outbreak, and yet few have been willing to cast blame on the state’s combative anti-vaccine movement. Enter Peter Hotez, an affable, bow-tie-wearing scientist who decided he’d had enough.
How To Keep The Earth As Inhabitable As Possible
We’ve been behind where we need to be for decades now, and the fact that we’ll be living in a hotter, less hospitable world is an inevitability. The only uncertainty left is how quickly we respond and how much damage we’re going to be able to prevent.
How The U.S. Betrayed The Marshall Islands, Kindling The Next Nuclear Disaster
Between 1946 and 1958, the United States detonated 67 nuclear bombs on, in and above the Marshall Islands — vaporizing whole islands, carving craters into its shallow lagoons and exiling hundreds of people from their homes.
Light Dawns: Why Is The Speed Of Light The Speed Of Light?
We have fixed the speed of light in a vacuum at exactly 299,792.458 kilometres per second. Why this particular speed and not something else? Or, to put it another way, where does the speed of light come from?
The Real Reason The Sound Of Your Own Voice Makes You Cringe
A common explanation is that because we normally hear our own voice while talking, we receive both sound transferred to our ears externally by air conduction and sound transferred internally through our bones. This bone conduction of sound delivers rich low frequencies that are not included in air-conducted vocal sound.
The Doomsday Invention: Will Artificial Intelligence Bring Us Utopia Or Destruction?
Philosopher Nick Bostrom argues that true artificial intelligence, if it is realized, might pose a danger that exceeds every previous threat from technology—even nuclear weapons—and that if its development is not managed carefully humanity risks engineering its own extinction.
Why Do Smart People Do Foolish Things?
Intelligence is not the same as critical thinking—and the difference matters. Most intelligence tests fail to capture real-world decision-making and our ability to interact well with others. This is why “smart” people do “dumb” things.
