By the end of this century, rice may not be what it used to be. As CO2 increases, rice loses B vitamins and other nutrients, which may put 600 million people at risk of nutritional deficiencies
The asteroid that killed the dinosaurs also baked Earth for 100,000 years. By analyzing tiny fish bones and teeth, researchers determined global CO2 levels reached 2,300 ppm following the impact. For comparison, CO2 levels recently climbed above 410 ppm for the first time in millions of years.
Depression speeds up brain aging, find psychologists. This is the first study that provides comprehensive evidence for the effect of depression on decline in overall cognitive function (also referred to as cognitive state), in a general population.
Abortions don’t lead to an increased risk of suicidal thoughts - Suicidal ideation was similarly low for women who had abortions and for those denied abortions. Policies requiring that women be warned that they are at increased risk of becoming suicidal if they choose abortion are not evidence based
More than 425,000 Australians live with dementia and a common, potentially life-threatening behaviour linked to the disease is wandering. Researchers to recommend a 'Silver Alert' system, similar to alerts for missing children, be activated when someone with dementia is reported lost.
For the first time a new study has shown how the size of interpersonal space changes depending on the tone and content of other people’s conversations, suggesting that the average size of someone’s interpersonal space becomes larger after listening to an aggressive conversation taking place nearby.
UCLA scientists have identified specific gut bacteria that play an essential role in the anti-seizure effects of the high-fat, low-carbohydrate ketogenic diet. The study, published in the journal Cell, is the first to establish a causal link between seizure susceptibility and the gut microbiota.
Men take shortcuts, while women follow well-known routes, finds a new study that suggests that men and women tend to adopt different navigation strategies and men navigate more efficiently than women.
A new study found that children on the threshold of obesity or overweight in the first two years of life had lower perceptual reasoning and working memory scores than lean children when tested at ages five and eight.
Studies in mice show that some of the effects of stress can be transmitted to offspring via environmentally-induced changes in sperm miRNA levels. A new study suggests that the same is true in humans, by showing the levels of the same miRNAs change in both men and mice exposed to early life stress

Titan’s windswept dunes may sprawl millions of more kilometers than previously thought and were likely formed by geological processes similar to those on Earth, according to a new study. The new findings could help scientists look for life or its molecular precursors on Saturn’s largest moon.
When it comes to getting one of their most critical nutrients, some plants recruit soil bacteria that live in their roots and harvest nitrogen from the air. A new study reveals that these partners are expensive to keep, however, so much so that some species have given up on these microbial gardeners
Scientists use improved algorithms and supercomputer power to predict the existence of a new di-baryon particle. The deuterium nucleus (proton-neutron thus 2 baryons in weak bond) is the only known di-baryon, and now scientists hope to conduct experiments to find this new particle as well.
Social media posts may signal whether a protest will become violent. Researchers found that people are more likely to endorse violence when they moralize the issue that they are protesting -- and when they believe that others in their social network moralize that issue, too
A new replication study of the well-known “marshmallow test” – a famous psychological experiment designed to measure children’s self-control – suggests that being able to delay gratification at a young age may not be as predictive of later life outcomes as was previously thought.
The Convoluted Ethics of Big Tech's Futurist Philanthropy: all lives have equal value, & that includes the many more people who will live in future generations than live today... our obligation [is] to invest now to improve the lives of all those coming into this world, not just those already here.
Study: Hot cars can hit deadly temperatures in as little as one hour - The team found that a child trapped in a car in the study’s conditions could reach hyperthermic temperatures in about an hour if a car is parked in the sun, and just under two hours if the car is parked in the shade.
Researchers have found that oxytocin mediates subjective duration of social interactions. They found that socially less proficient individuals were less susceptible to the effect of "subjective time" than socially proficient ones. Social proficiency has been linked to one’s endogenous oxytocin level
Obesity is linked to as many as 12 different forms of cancer, according to new research which advises giving up bacon and swapping sugary drinks for water as part of a 10-point plan for avoiding the disease. Obesity will overtake smoking as the biggest cause of cancer within a couple of decades.
Students from some of England’s worst performing secondary schools who enrol on medical degrees with lower A Level grades, on average, do at least as well as their peers from top performing schools, a new study has revealed.
A new study suggests that people can identify grandiose narcissists by the distinctiveness of their eyebrows. Using image manipulation, the study found that a non-narcissist donning a narcissistic person’s brows was judged as more narcissistic, and vice-versa.
Scientists have created a pill-size device that can detect bleeding deep inside a pig’s digestive tract and relay that information via a wireless signal to a cellphone. If modified to detect other chemicals this could be incredibly useful for human medical use.

Logical fallacies play a huge role in how people think and in how they communicate. Understanding how fallacies work and why they occur is the key to understanding how you can deal with them effectively.
Research suggests rising temperatures are encouraging antibiotic resistance in cities across the United States. Until now, health researchers assumed antibiotic resistance was primarily the result of overprescription and overuse. But a new study suggests climate change is also to blame.
Many people think of lactate as the cause of muscle fatigue, reduced performance, and pain. It isnt, it’s often the preferred source of energy in the body: The brain and heart both run more efficiently, strongly when fueled by lactate rather than by glucose
Scientists expect thermoelectric materials (heat to electricity) to double in efficiency when placed in an ambient magnetic field (MRI machine level or higher). The topological semimetals studied could be used in industrial power plants to recover electricity from waste heat.
Research highlights the psychological dangers of long-haul space flights particularly to Mars. Communication with family and friends will be extremely minimal. Even talking to Mission Control will be difficult, given that signals to and from the craft will take almost an hour to arrive.
Religious individuals are, on average, less humble about their intellectual prowess than non-religious individuals, and it is right-wing authoritarianism that accounts for most of the correlation between religiosity and lack of intellectual humility, study shows.

In honor of my Pacific Crest Trail thru hike last year, the Steller's Jay. These loud, beautiful bastards followed me from Mexico to Canada - done by Annelise Kinney at Diving Swallow Tattoo, Oakland, CA.
Quaillike creatures were the only birds to survive the dinosaur-killing asteroid impact. A new study suggests that widespread forest fires made it impossible for tree-dependent birds to survive, meaning the vast avian diversity of today likely arose from just a few ground-dwelling survivors.
An argument against every general theory of consciousness: Every theory unjustifiably assumes either the falsity of panpsychism, the falsity of highly restricted views of consciousness, or both.
A new study has found children and adolescents who grow up with one or more of these environmental risk factors are likely to resort to violence, aggression and crime as adults, irrespective of an underlying mental illness
Scientists have discovered three vast canyons in one of the last places to be explored on Earth - under the ice at the South Pole. The deep troughs run for hundreds of kilometres, cutting through tall mountains - none of which are visible at the snowy surface of the continent.

The asteroid that hit the Earth 66 million years ago decimated Earth's forests, leading to the extinction of three-quarters of all plant and animal life. Study suggests that among the survivors were ferns and hardy, ground-dwelling birds.
Alabama police shot a teen dead, but his friend got 30 years for the murder. Kant might argue this violates the respect principle, which holds that we can only punish people for things they've actually done
Actualism is a widely-held view in the metaphysics of modality, which represents the philosophical position that everything there is must exist. This is in contrast with Possibilism, which states that there are things that do not exist, but which could have existed.
The dominant hypothesis for why we evolved such large brains suggests that challenging social interactions were the driving force. A new study finds evidence against this idea and shows that human brain expansion was likely driven by ecology.
Stringent limits on global warming would bolster the world economy by averting tens of trillions of dollars in damage this century from heat waves, droughts and floods, a U.S. study said on Wednesday.
“Heidegger’s central postmodern insight into the inexhaustible plurality of being serves best to justify and promote a robust liberal tolerance, a tolerance intolerant only of intolerance itself. ”
