A ‘spooky’ effect of physics that Einstein couldn’t believe has been photographed for the first time


quantum entanglement image picture pa moreau et al science advances enlarged

  • Albert Einstein‘s work in part led to the prediction of quantum entanglement: the idea that two particles can remain connected across vast distances of space and time.
  • Einstein found the idea absurd and "spooky," but it has since been proven with countless quantum physics experiments.
  • No had ever photographed entangled photons (pieces of light), though, until one research team recently did so with a high-tech laser experiment.
  • Visit Business Insider’s homepage for more stories.

The black-and-white photo above isn’t much to look at. However, the ghostly, eye-like shapes illustrate a strange phenomenon that rattled Albert Einstein so much that he died disbelieving it could exist.

The picture represents the first-ever photograph of quantum entanglement, or the "spooky" pairing of particles.

"The image we’ve managed to capture is an elegant demonstration of a fundamental property of nature, seen for the very first time in the form of an image," Paul-Antoine Moreau, a physicist at the University of Glasgow, said in a press release.

Moreau led a team of researchers who managed to create the image, which the group published in a study on Friday in the journal Science Advances.

Quantum entanglement 101

Quantum entanglement is the now well documented idea that two tiny particles can be paired and separated, yet remain intimately and instantly connected across vast distances.

By the laws of physics, two particles can get entangled with a binary, yes-or-no-like property or state, such as spin or phase polarization. But that state remains fuzzy — or in "superposition" — until one particle is measured. Then at the exact moment of observation, even if the particles are separated by light-years of space, the other particle takes on the opposite state of its twin.

To understand this concept, imagine each entangled particle were a box containing a cat. The cat inside would be both alive and dead at the same time — that is, until someone opened one of the boxes. If the cat seen in one box was alive, then the cat in the other box would have to be dead (or vice versa).

Einstein thought this teleportation-like effect was so absurd that he described it as "spooky action at a distance."

"Einstein couldn’t accept this," J.C. Séamus Davis, a physicist at Cornell University who studies quantum mechanics, previously told Business Insider. "He essentially went to his grave not accepting this as fact, but it’s now been shown millions of times to work."

One of the latest studies to prove it, published in February 2017, used 600-year-old starlight to show that two particles couldn’t "cheat" at the moment of entanglement and share a state before being measured.

How and why small particles can get entangled makes no sense in the context of our everyday lives. At tiny scales, the universe appears to play by different rules, many of which are paradoxical and defy reason. In some quantum-mechanical scenarios, for instance, an effect doesn’t always follow a cause; the effect can, in fact, happen before its cause occurs.

No one should be blamed for being confused by quantum mechanics, Davis said, since "we didn’t evolve to understand" the theory and its counterintuitive ramifications.

"But the math, the predictions starting in the 1920s, have all turned out to be correct," he said. "It’s the most successful scientific theory in the human race."

In all those decades, however, no one has ever captured an image of entangled particles. So that is what Moreau and his colleagues set out to do.

How entanglement was photographed for the first time

quantum entanglement image picture setup lasers pa moreau et al science advances

Particles of light called photons can be entangled by a number of quantum properties. With their experiment, though, the researchers chose a property called phase. The photons came out of an ultraviolet laser beam, then passed through a special crystal known to entangle the phase of some photons.

Next, their experiment split the beam into two equal "arms" with a beam splitter, or half-mirrored glass. At this point, some of the photons that the crystal had entangled parted ways.

One arm of photons passed through a filter to limit the particles to one of four phases (a phase filter effectively "measures" that property of a photon, so it’d instantly cause its partner to flip). Then the photons went into a very sensitive camera that’s able to detect individual photons. The other arm led to a high-speed trigger device for the camera.

The camera sensor recorded information only when two entangled photons — each from a separate arm — arrived at their respective detectors at same time and with opposite phases.  Over time, the researchers built up a patterned image of the entangled photons striking the camera.

Entangled photons that passed through the phase filter were expected to form four eye-like patterns, and that’s exactly what the image showed.

The experiment piles on more proof that what spooked Einstein is real, but also that entangled particles might be used in future imaging applications in science, Moreau said.

Wedding photographer’s rant against guests ruining shots with smartphones goes viral


Wedding photographer’s rant against guests ruining shots with smartphones goes viral

by Leave a Comment

It’s a common complaint of wedding photographers and happy couples alike. Although, with the latter, it’s typically after the wedding when they see how many of their friends and relatives have ruined the paid photographer’s shots by standing in the way with smartphones and even iPads to get snaps of their own. Fortunately, more couples are speaking out and going “unplugged”, but word hasn’t spread to everybody yet.

For photographer Hannah Mbalenhle Stanley of Hanna Way Photography, she faced one iPhone too much recently and posted a rant to Facebook expressing her thoughts. It’s since been shared over 150,000 times, with over 140,000 reactions and has left commenters divided.

The post reads…

To the girl with the iPhone…
Not only did you ruin my shot, but you took this moment away from the groom, father of the bride, and the bride. What exactly do you plan on doing with that photo? Honestly. Are you going to print it out? Save it? Look at it everyday? No. You’re not. But my bride would have printed this photo, looked at it often and reminisced over this moment as her dad walked her down the aisle on her wedding day. But instead, you wanted to take a photo with your phone, blocking my view, and taking a photo that you will not use.
Guests, please stop viewing weddings you attend through a screen but instead turn OFF your phone, and enjoy the ceremony. You are important to the bride and groom, you would not be attending the wedding otherwise. So please, let me do my job, and you just sit back, relax and enjoy this once in a lifetime moment.

Wedding photographers

The responses to Hannah’s post have been mixed, with some saying that the guests are more important and have the right to do what they want, and others backing up Hannah’s position completely. Personally, if guests at my wedding started getting in the way of the person I’d paid to be there and record the day, I’d be pissed.

This one of the reasons why I won’t ever shoot weddings. It’s just too much of a headache for me to want to deal with. But for those of you that do, how do you deal with smartphone-wielding guests? And if it was your wedding, how would you feel if your guests were constantly in the way of the photographer you’d hired to be there?

Harvard’s camera can show you the world through the eyes of a shrimp


Shrimp and insect species that can see polarized light experience the world in a much, much different way than we do — just take look at the image above to see what we mean. The only way we can get a glimpse of their polarized world is through devices like cameras, but polarization cameras are bulky and pricey at this point in time, limiting their potential applications. Harvard’s portable and compact camera that can image polarization in a single shot, however, could change all that.

Paul Chevalier, one of the co-authors of the study published in Science, explained how polarization can help us:

"Polarization is a feature of light that is changed upon reflection off a surface. Based on that change, polarization can help us in the 3D reconstruction of an object, to estimate its depth, texture and shape, and to distinguish man-made objects from natural ones, even if they’re the same shape and color."

Unlike the big and bulky polarization cameras used today, the one developed by researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) is about the size of a thumb. And even with a lens and a protective case, it’s just as big as a small lunchbox. The researchers used nanoscale structures to design a device small and uncomplicated enough to be incorporated into existing imaging systems, such as the one on your phone.

They believe it could be used on autonomous vehicles to give them a boost in terms of being able to detect objects on the road. It could also be used to give planes and satellites the ability to detect camouflaged objects or to distinguish between man-made and natural structures. Simply put, they believe their research is a game changer and that their camera could enable the widespread adoption of polarization imaging.

A scientist who won the Nobel Prize for revolutionizing how we treat cancer says young scientists shouldn’t set out to cure the disease


Jim allison immunotherapy cancer

  • Jim Allison won the Nobel Prize last year for transforming the way that cancer is treated, along with Tasuku Honjo, a scientist at Kyoto University.
  • At the start of his career, Allison didn’t set out to cure cancer. Instead, he wanted to better understand how a part of the human immune system worked in the body. 
  • That led to immunotherapy treatments that fight cancer by using the body’s built-in immune system. 
  • His advice for young scientists is: "work on what really interests you, and you care about. Don’t worry if it has any impact on cancer, at least not when you’re working on it." 
  • Click here for more BI Prime stories.

For Jim Allison, cancer has always been at the back of his mind. He’d lost many family members to the disease, including his mother when he was young, and is himself a cancer survivor.

But when Allison started off his scientific career decades ago, "I didn’t set out saying, ‘I’m going to cure cancer,’" Allison told Business Insider.

Instead, the scientist pursued something he found fascinating: the human immune system, which naturally fends off infections and disease.

Allison’s work in this area would pave the way for immunotherapy treatments, which use the body’s natural immune system to fend off cancer and transformed the way the disease is treated. For that, Allison and Tasuku Honjo won the Nobel Prize last year. 

So his advice for young scientists is to "work on what really interests you," Allison says. "Don’t worry about if it has any impact on cancer, at least not when you’re working on it."

Instead, "study the fundamental mechanisms until you really learn how things work," Allison added, speaking with Business Insider after a panel about cancer immunotherapy last month that was hosted by the nonprofit Cancer Research Institute

Cancer cell

Allison, who holds a doctorate in biological sciences from The University of Texas at Austin, has long worked in academia conducting research about a component of the immune system called T cells.

A Texan and scientist through and through, he’s now the chair of the immunology department at the MD Anderson Cancer Center in Texas and director of the Parker Institute for Cancer Immunotherapy, which was set up by the internet billionaire Sean Parker

At the most basic level, Allison’s passion has been to understand how diseased cells get noticed in the body by T cells. T cells then kill those sick cells.

"And that has nothing to do with cancer. Or everything, depending on how you look at it," he says. 

That scientific work was then harnessed for drugs that stimulate the immune system to fight cancer.

In any case, Allison says he wasn’t worried about where that research would lead. 

"Well, the immune system is important in many kinds of disease. I figured it would go somewhere," he said.

A newly discovered species of African fish with gleaming purple scales has been named after Wakanda, the fictional home of Marvel’s Black Panther


wakanda fish

  • Divers have discovered a new species of wrasse — a brightly-colored marine fish — in the waters off Zanzibar, Tanzania.
  • They named the fish Cirrhilabrus wakanda, after the fictional country that’s home to Marvel superhero Black Panther.
  • The fish’s common name is "vibranium fairy wrasse," after the powerful metal that lines the Black Panther’s suit. The scientists said the creature’s gleaming purple scales reminded them of the vibranium-laced outfit.
  • Visit Business Insider’s homepage for more stories.

Deep in the Indian Ocean, off the coast of Zanzibar, Tanzania, swims a tiny, reclusive, and colorful fish.

Its deep purple scales, set in a chain-link pattern, reminded scientists of the high-tech suit worn by the superhero Black Panther.

So they named the previously-undiscovered, 2-inch-long fish Cirrhilabrus wakanda, after the Black Panther’s mythical African country, Wakanda.

In a new study, researchers describe the creature, whose common name is "vibranium fairy wrasse" — a moniker that gives a nod to the fantastical, near-indestructible metal that lines the Black Panther’s superhero suit.

"When we thought about the secretive and isolated nature of these unexplored African reefs, we knew we had to name this new species after Wakanda," Yi-Kai Tea, lead author of the new study, said in a press release. "We’ve known about other related fairy wrasses from the Indian Ocean, but always thought there was a missing species along the continent’s eastern edge. When I saw this amazing purple fish, I knew instantly we were dealing with the missing piece of the puzzle."

Diving to reefs up to 260 feet below the surface

zanzibar dive site

The vibranium fairy wrasse prefers the remote, dimly lit waters of the "twilight zone," hiding among tropical coral reefs up to 260 feet below the surface.

That depth is far below recreational diving limits and extremely challenging for humans to access, which is why the fish has gone undiscovered for so long, the scientists said.

Tea’s team, used special gear in order to dive hundreds of feet down. Their closed-circuit, multi-tank diving equipment recycles their breath to use every last bit of oxygen, but even that technology only allows them a few minutes to explore and document the deep before they have to swim back to the surface. 

"When we reach these reefs and find unknown species as spectacular as this fairy wrasse, it feels like our hard work is paying off," Luiz Rocha, another study author and a diver, said in a press release.

Colorful males and females

In their deep dives, scientists were able to scoop up sample fish and return them to the surface. 

Under a microscope, they analyzed the fish’s scales, fins, body structure, and DNA, and determined that it was a new species previously unknown to science. Both male and female wrasses boast a vibrant purple color with a pair of facial stripes above their eyes. Their fins and tails are also a beautiful two-toned color.

wakanda fish

Surprisingly, the wrasse’s purple scales stayed vibrant and gleaming even after being preserved in alcohol for future research. Usually fish scales lose their color during that process.

The vibranium fairy wrasse joins a family of seven other fairy wrasse species in the western Indian Ocean, with some extended fishy relatives in the Pacific.

But as the planet and its oceans warm — last year was the hottest on record for the world’s oceans — the coral reefs where these fish live are at risk of extinction. Oceans absorb 93% of the extra heat that man-made greenhouse gases trap in Earth’s atmosphere, and warmer oceans lead corals to expel the algae living in their tissues and turn white. That process is known as coral bleaching.

As a consequence, coral reefs, and the marine ecosystems they support, are dying. Around the world, about 50% of the world’s reefs have died over the past 30 years.

"It’s a time of global crisis for coral reefs, and exploring little-known habitats and the life they support is now more important than ever," Rocha said. "Because they are out of sight, these deeper reefs are often left out of marine reserves, so we hope our discoveries inspire their protection."

An incredible new 60-second animation shows where 4,000 planets beyond our solar system are located in deep space


exoplanet extrasolar planet locations night sky nasa kepler tess data animated map milky way galaxy apod system sounds russo santaguida

Earth is not alone, and a stunning new animation created using NASA data beautifully illustrates that point.

There may be trillions of other planets in our galaxy, the Milky Way (which itself is one of hundreds of billions of other galaxies in the universe). But finding such extrasolar planets, or exoplanets, is not easy — even when they’re relatively close by.

In fact, it takes more than four years for light to travel from the nearest star to our solar system. Meanwhile, exoplanets are both small and dim, and the Milky Way is a 100,000 light-year-wide haystack for astronomers to scour.

Despite their long odds, however, astronomers have logged thousands of exoplanets since a team confirmed the existence of the first one in October 1991. This June, in fact, marked a milestone: researchers logged the 4,000th discovery in an ever-growing NASA archive of exoplanets.

To celebrate the achievement, two artists pulled all of that data and compiled it into a short animated map and timeline called "4000 Exoplanets," shown below.

The animation was created by artist Matt Russo and scored by musician Andrew Santaguida, who both work with a science-art outreach project called System Sound. The short film was published to YouTube on Sunday and described on Wednesday by NASA’s Astronomy Picture of the Day (APOD) site.

What the animated exoplanet timeline shows

The video shows a flattened map of the 360-degree night sky as seen from Earth. The bright band of stars in the center is a cross-cut view of the Milky Way; it looks this way because our solar system drifts within the spiral galaxy.

milky way galaxy sun solar system earth location nasa labeled 1200

Each circle that appears represents a confirmed exoplanet discovery. The main method used to find each world is shown as one of seven colors.

For example, purple circles show a planet found by its transit, or passage in front of a parent star; this is detectable because it causes periodic, subtle drops in the parent star’s brightness level relative to Earth. Pink, meanwhile, shows distant worlds that were located because their gravitational pull was strong enough to make their star "wiggle" sufficiently for astronomers to detect.

Read more: Jupiter is so big it does not actually orbit the sun

The pace of discoveries in the 60-second timeline starts off slowly, with only about 70 extrasolar worlds located in the first decade of discoveries. That’s because finding and confirming the existence of exoplanets was extraordinarily difficult without advanced tools and resources.

But as funding grows, techniques improve, more ground telescopes help with the search, and new space observatories launch into space, the rate at which exoplanets have been found has increased. The pace of discovery really exploded after 2009, when NASA launched its Kepler Space Telescope.

Kepler focused its search on a small patch of the sky and used the transit method of exoplanet detection on 150,000 stars. This is why, in the animation, a big purple blob suddenly begins to appear around 2010 (at top-left) and the exoplanet count skyrockets.

NASA deactivated Kepler in late 2018, but in April 2018, NASA launched a similar planet hunter called the Transiting Exoplanet Survey Satellite (TESS).

TESS is expected to scan 200,000 nearby stars across 85% of the night sky, revealing thousands of additional planets. Below is an animation of TESS’ planned survey.

Around 50 of the planets TESS detects should be Earth-size and potentially habitable, creating promising targets for more detailed observations by telescopes that can image objects much deeper in space.

The first pictures of Earth-like worlds may come from enormous ground-based observatories, including the Giant Magellan Telescope in Chile, which are poised to come online starting in the mid-2020s. Astronomers hope such telescopes can take raw exoplanet discoveries a step further by picking up light from their atmospheres — and potentially "sniffing" out biosignatures that may indicate the presence of alien life.

Cannabis processing startups hope to unlock new chemicals and treatments


Jeff Ubersax knows yeast.

The chief executive officer of Demetrix studied yeast genetics and biochemistry in school and was an early employee at Amyris Biotechnologies, a technology company that was using fermentation to make biofuels back in the early days of the first clean technology boom back in 2008. 

Now, the same technology that Ubersax and Jay Keasling, the celebrated professor from the University of California at Berkeley who co-founded Amyris and Demetrix, used to make biofuels is being applied to the production of cannabis.

The company launched with an $11 million seed round led by Horizons Ventures, a Hong Kong-based investment fund backed by the multi-billionaire real estate mogul Li Ka-shing, to begin commercializing the technology that Keasling had been researching in his lab.

The goal was to refine a process that would enable yeasts to make a range of cannabinoids that are found in the marijuana plant which could be used to develop new pharmaceuticals, additives and supplements for use in clinical and consumer applications. The technology works much the same way as brewing beer. Except instead of fermenting to produce alcohol, the fermentation process produces cannabinoids from genetically modified yeast cells.

While the technology holds promise, it’s still got a long way to go before it becomes competitive with extracts from the marijuana plant, but given new capital infusions the tide is turning.

Demetrix, for instance, has raised another $50 million from Horizons Ventures and Tuatara Capital, an investment firm focused on the legal cannabis industry, to significantly expand its production while simultaneously pursuing initial tests on the efficacy of rare strains of cannabinoids as treatments for certain illnesses.

“Natural cannabinoids have been used for a really long time,” says Ubersax. And last June the U.S. Food and Drug Administration approved the first pharmaceutical derived from cannabis, Epidiolex, as a treatment for patients with epilepsy.
