Your photo could soon reveal your political views, says a Stanford professor.
Voters have a right to keep their political beliefs private. But according to some researchers, it won't be long before a computer program can accurately guess whether people are liberal or conservative in an instant. All that will be needed are photos of their faces.

Michal Kosinski - the Stanford University professor who went viral last week for research suggesting that artificial intelligence (AI) can detect whether people are gay or straight based on photos - said sexual orientation was just one of many characteristics that algorithms would be able to predict through facial recognition.

The 'electric cars aren't green' myth debunked (sort of)

electric cars emissions

It's time to bust this thing wide open.

'Electric cars aren't green' is a great bit of counter-intuitive headline bait, but it's bad maths. This is how the argument goes, again and again...

Electric cars have higher manufacturing emissions than normal cars. Electric cars also use electricity that has its own footprint. And put together these two factors are a 'dirty little secret' that negate any climate benefit of electric cars!

No. Let's clear this thing up once and for all.

Comment: It's a big 'if'. As things stand, most 'juice' in most countries is from fossil-fuel-powered electric grids. The only reason France has 'green-juice-electric cars' is because they're nuke-powered, which no self-respecting 'climate-savior' would ever consider 'green'!

As the author himself says: "real life comes in shades of grey."

Restrain your baby and let the robo-crib rock them to sleep?

snoo, baby, crib

Looks comfy?
Would you trust a robot to rock your baby to sleep? The question likely elicits the chilling vision of a Terminator cradling your child. However, a new product - the Snoo - is, in fact, an automated crib, a high-tech bassinet perfectly calibrated to 'swaddle' infants and lull them into slumber. It's an early entry of automated child care in an age that promises to integrate robotics into the daily fabric of human life.

So, back to the question at hand:

Would you trust a robot to swaddle your child while she sleeps?


The Snoo was developed by renowned pediatrician Dr. Harvey Karp, MIT-trained engineers, and Yves Behar, who runs a tech-savvy industrial design firm. The team's goal was to recreate the sensations of being in the womb by swaddling the infant - restricting their limb movement, a practice some have criticized - and inundating them with white noise. This is accomplished with a sleeper outfit that one mother, Samantha Murphy Kelly, referred to as a "straight jacket" that safely secures the child as the bassinet rocks her to sleep.

Toxoplasma parasite effects severely underestimated

Two billion people are infected with the Toxoplasma Gondi parasite, most commonly contracted from cats.
Except for a couple of specific circumstances - notably pregnancy - the world's most common parasite in humans, Toxoplasma gondii, is thought to induce few symptoms and no serious effects.

However, research from 32 scientists at 16 institutions, linking parasite proteins with small non-coding human RNA molecules known as microRNA, and comparing outcomes for various diseases between infected and non-infected people, suggests we have severely underestimated the situation.

The research, published in the journal Scientific Reports, implicates T. gondii in the progress of neurodegenerative diseases, epilepsy, and certain cancers.

Around the world, more than two billion people carry the parasite. The most common route of infection involves one of its primary reservoirs, the domestic cat. Parasite eggs find their way into humans - and many other animals - via contact with cat faeces.

Such contact does not need to be direct. T. gondii eggs are extremely resilient and can survive dormant for many months in open environments - these frequently include vegetable patches and fields, where cats may defecate into the soil, from which the eggs are transferred to harvested plants.

The parasite, once hatched, lodges in the brain.

China's mysterious 'physics-defying' EmDrive could allow journey to Mars in weeks

China's announcement would put them ahead of NASA in the race for an EM Drive.
A mysterious propulsion system that 'defies physics' may be close to reality in China, where scientists say they have finished work on the EmDrive. Much sought after by space agencies, the system could potentially allow for travel to Mars in weeks. Scientists in China claim to have developed a working prototype of the EmDrive, according to state TV, with a test due to take place in space in the near future. Developed by scientist Dr Chen Yue at the China Academy of Space Technology (CAST), it would put China's space agency ahead of NASA.

The EmDrive is key to the future of space exploration, eliminating the need for a conventional propellant to produce thrust. "For every action there must be an equal and opposite reaction," Newton's Third Law states, emphasizing the need for propellant in all modes of travel. China claims to have defied that law, producing an EmDrive that produces thrust by bouncing microwaves around in a closed container with no propellant required. In theory, this is the equivalent of "trying to pull yourself up by your shoelaces and hoping you'll levitate," Steven Thomson of the University of St Andrews said in 2015.

Comment: China has leapfrogged other countries in terms of technology development over the past 15 years.

Scientists find evidence linking Antarctic volcanic eruptions to ancient climate change in the Southern Hemisphere

A 15-meter pan-sharpened Landsat 8 image of the Mount Takahe volcano rising more than 2,000 meters (1.2 miles) above the surrounding West Antarctic ice sheet in Marie Byrd Land, West Antarctica.
New findings published today in the Proceedings of the National Academy of Sciences of the United States of America (PNAS) by Desert Research Institute (DRI) Professor Joseph R. McConnell, Ph.D., and colleagues document a 192-year series of volcanic eruptions in Antarctica that coincided with accelerated deglaciation about 17,700 years ago.

"Detailed chemical measurements in Antarctic ice cores show that massive, halogen-rich eruptions from the West Antarctic Mt. Takahe volcano coincided exactly with the onset of the most rapid, widespread climate change in the Southern Hemisphere during the end of the last ice age and the start of increasing global greenhouse gas concentrations," according to McConnell, who leads DRI's ultra-trace chemical ice core analytical laboratory.

Climate changes that began ~17,700 years ago included a sudden poleward shift in westerly winds encircling Antarctica with corresponding changes in sea ice extent, ocean circulation, and ventilation of the deep ocean. Evidence of these changes is found in many parts of the Southern Hemisphere and in different paleoclimate archives, but what prompted these changes has remained largely unexplained.

"We know that rapid climate change at this time was primed by changes in solar insolation and the Northern Hemisphere ice sheets," explained McConnell. "Glacial and interglacial cycles are driven by the sun and Earth orbital parameters that impact solar insolation (intensity of the sun's rays) as well as by changes in the continental ice sheets and greenhouse gas concentrations."

Facial recognition algorithm that identifies sexual orientation has LGBT community in uproar over potential uses

Gay AI identification software

The study created composite faces judged most and least likely to belong to homosexuals
A facial recognition experiment that claims to be able to distinguish between gay and heterosexual people has sparked a row between its creators and two leading LGBT rights groups.

The Stanford University study claims its software recognises facial features relating to sexual orientation that are not perceived by human observers.

The work has been accused of being "dangerous" and "junk science".

But the scientists involved say these are "knee-jerk" reactions.

Details of the peer-reviewed project are due to be published in the Journal of Personality and Social Psychology.

AI algorithms are getting schooled on fairness

There is more than one approach to trimming unintended biases from the machines that we are teaching to make more and more of our decisions.
Machine-learning programs can introduce biases that may harm job seekers, loan applicants and more

You've probably encountered at least one machine-learning algorithm today. These clever computer codes sort search engine results, weed spam e-mails from inboxes and optimize navigation routes in real time. People entrust these programs with increasingly complex - and sometimes life-changing - decisions, such as diagnosing diseases and predicting criminal activity.

Machine-learning algorithms can make these sophisticated calls because they don't simply follow a series of programmed instructions the way traditional algorithms do. Instead, these souped-up programs study past examples of how to complete a task, discern patterns from the examples and use that information to make decisions on a case-by-case basis.

Unfortunately, letting machines with this artificial intelligence, or AI, figure things out for themselves doesn't just make them good critical "thinkers," it also gives them a chance to pick up biases.

A new look at archaic DNA tells a different story of human evolution

These population trees with embedded gene trees show how mutations can generate nucleotide site patterns. The four branch tips of each gene tree represent genetic samples from four populations: modern Africans, modern Eurasians, Neanderthals, and Denisovans. In the left tree, the mutation (shown in blue) is shared by the Eurasian, Neanderthal and Denisovan genomes. In the right tree, the mutation (shown in red) is shared by the Eurasian and Neanderthal genomes.
Hundreds of thousands of years ago, the ancestors of modern humans diverged from an archaic lineage that gave rise to Neanderthals and Denisovans. Yet the evolutionary relationships between these groups remain unclear.

A University of Utah-led team developed a new method for analyzing DNA sequence data to reconstruct the early history of the archaic human populations. They revealed an evolutionary story that contradicts conventional wisdom about modern humans, Neanderthals and Denisovans.

The study found that the Neanderthal-Denisovan lineage nearly went extinct after separating from modern humans. Just 300 generations later, Neanderthals and Denisovans diverged from each other around 744,000 years ago. Then, the global Neanderthal population grew to tens of thousands of individuals living in fragmented, isolated populations scattered across Eurasia.

Scientists have discovered that while monstrous dinosaurs roamed the earth, the insect world contained its own fearsome creature - a 'hell ant' with a reinforced metal horn on its head.

A number of extinct insects have been given the sinister 'hell ant' moniker - including the Haidomyrmex cerberus, which had curious L-shaped mandibles.

But researchers from the New Jersey Institute of Technology have revealed a new hair-raising creature found inside amber, dating back 99 million years.

According to the study, the hell ant, known as Linguamyrmex vladi, hunted and defended itself in ways which differ dramatically from modern ants.
