Researchers believe they can diagnose depression by looking at Instagram photos

It may seem that everyone on Instagram is living their best life, but according to new research photos that are bluer, darker, and less populated might reveal a struggle with mental health.

Researchers from the University of Vermont and Harvard University, have found that they could diagnose depression by using machine learning to study the composition of Instagram photos.

According to the researchers, photos that are bluer, more gray, dark or with fewer faces indicate that the profile’s owner has depressive tendencies.

The computer’s detection rate of 70% is more reliable than the 42% success rate of general-practice doctors diagnosing depression in-person.

“This points toward a new method for early screening of depression and other emerging mental illnesses,” says Chris Danforth, a professor at the University of Vermont who co-led the new study. “This algorithm can sometimes detect depression before a clinical diagnosis is made.”

“So much is encoded in our digital footprint. Clever artificial intelligence will be able to find signals, especially for something like mental illness.”

To conduct the study, the researchers used the Instagram feeds of 166 people, around half of whom had reported having been clinically depressed in the last three years.

The researchers then collected and analysed 43,950 photos, using insights from well-established psychology research, about people’s preferences for brightness, colour, and shading. They also investigated the filters used by healthy and mentally ill people.

They found that healthy individual chose Instagram filters, like Valencia, that gave their photos a warmer brighter tone. Among depressed people the most popular filter was Inkwell, making the photo black-and-white.

Faces in photos also turned out to provide signals about depression. The researchers found that depressed people were more likely than healthy people to post a photo with people’s faces—but these photos had fewer faces on average than the healthy people’s Instagram feeds.

“People suffering from depression were more likely to favour a filter that literally drained all the colour out the images they wanted to share,” said Danforth and Andrew Reece of Harvard University who co-wrote the study.

“Fewer faces may be an oblique indicator that depressed users interact in smaller settings.”

More than half of a general practitioners’ depression diagnoses are false, but the computational algorithm was able to achieve a detection rate of 70%, while GPs are said to have only a 42% success rate.

The new study also shows that the computer model was able to detect signs of depression before a person’s date of diagnosis. “This could help you get to a doctor sooner,” Danforth says. “Or, imagine that you can go to doctor and push a button to let an algorithm read your social media history as part of the exam.”

DeepMind’s Go-playing AI can learn the game for itself now

Google’s AI subsidiary DeepMind believes it is one step closer to creating AI with general intelligence because its Go-playing software, AlphaGo, has been updated and can now teach itself how to play. AlphaGo Zero was only programmed with Go's basic rules, and from there it learns everything else by itself.

UK spies monitoring social media in mass surveillance tactic

The privacy rights group Privacy International says it has obtained evidence for the first time that UK spy agencies are collecting social media information on potentially millions of people. The discovery raises concerns about whether effective oversight of the mass surveillance programs is in place.

Blue Origin passes hot-fire test

Blue Origin, the aerospace company fronted and largely funded by Jeff Bezos, has released footage of its BE-4 engine's first and successful completion of a hot-fire test. The successful hotfire supports the idea that Blue Origin could in the future be used for orbital and deep space missions.

Climate change makes it more likely to see hurricanes in Europe

Meteorologists from the University of Bristol have predicted that the likelihood of hurricane-force storms hitting the UK, much like Hurricane Ophelia did this week, will be enhanced in the future due to human-induced climate change.

Human habitat located on the Moon that will shield us from its extreme elements

Researchers have discovered a potential habitat on the Moon, which may protect astronauts from hazardous conditions on the surface.

No one has ever been on the Moon for longer than three days, largely because space suits alone can’t shield astronauts from its elements: extreme temperature variation, radiation, and meteorite impacts. Unlike Earth, the Moon also has no atmosphere or magnetic field to protects its inhabitants.

However, in a study published in Geophysical Research Letters, researchers have claimed that the safest place for astronauts to seek shelter is inside an intact lava tube.

“It’s important to know where and how big lunar lava tubes are if we’re ever going to construct a lunar base,” said Junichi Haruyama, a senior researcher at JAXA, Japan’s space agency.

Lava tubes are naturally occurring channels formed when a lava flow develops a hard crust, which thickens and forms a roof above the still-flowing lava stream. Once the lava stops flowing, the tunnel sometimes drains, forming a hollow void.

The Lava tubes located by Purdue University researchers are said to be spacious enough to house one of the United States’ largest cities, and while their existence – and in particular their entrance near the Marius Hills Skylight – was previously known, their size was previously an unknown quantity.

“They knew about the skylight in the Marius Hills, but they didn’t have any idea how far that underground cavity might have gone,” said Jay Melosh, professor of Earth, Atmospheric and Planetary Sciences at Purdue University.

“Our group at Purdue used the gravity data over that area to infer that the opening was part of a larger system. By using this complimentary technique of radar, they were able to figure out how deep and high the cavities are.”

At the first meeting of the US’ reintroduced National Space Council, vice president Mike Pence announced that the Trump administration will redirect America’s focus to travelling back to the Moon.

Pence’s declaration marks a fundamental change for NASA, which abandoned plans to send people to the moon in favour of Mars under President Barack Obama.

“We will return NASA astronauts to the moon – not only to leave behind footprints and flags, but to build the foundation we need to send Americans to Mars and beyond,” Pence said.
