Researchers find birds can theorize about the minds of others, even those they cannot see | Phys.org

The question of what sets humans apart from other animals is one of the oldest philosophical puzzles. A popular answer is that only humans can understand that others also have minds like their own.

But new research suggests that ravens - birds singled out by many cultures as a symbol of intelligence and wisdom - share at least some of the human ability to think abstractly about other minds, adapting their behavior by attributing their own perceptions to others.

The study, "Ravens Attribute Visual Access to Unseen Competitors," was published Feb. 2 in Nature Communications. It found that ravens guarded caches of food against discovery in response to the sounds of other ravens if a nearby peephole was open, even if they did not see another bird. They did not show the same concern when the peephole was closed, despite the auditory cues.

The findings shed new light on science's understanding of Theory of Mind, the ability to attribute mental states - including vision - to others, said Cameron Buckner, assistant professor of philosophy at the University of Houston. Buckner is an author of the paper, along with Thomas Bugnyar and Stephan A. Reber, cognitive biologists at the University of Vienna.

Can Physicians Work in US Immigration Detention Facilities While Upholding Their Hippocratic Oath? | JAMA

The modern successor to the Hippocratic oath, called the Declaration of Geneva, was updated and approved by the World Medical Association in 2017. The pledge states that “The health and well-being of my patient will be my first consideration” and “I will not use my medical knowledge to violate human rights and civil liberties, even under threat.”1 Can a physician work in US immigration detention facilities while upholding this pledge?

Scientists Just Detected Brain Waves in Mini Lab-Grown Brains | Mother Jones

For the first time, scientists have detected brain waves similar to those of a pre-term baby in miniature, lab-grown brains.

The results, published Thursday in the journal Cell Stem Cell, have big implications for the medical field. Access to human brains are a consistent barrier to studying conditions like Alzheimer’s, autism, or schizophrenia; for obvious reasons, infant brains are even more difficult to obtain. So models that are grown from stem cells like these mini-brains (known to scientists as “cortical organoids”) may offer a solution.

A Successful Artificial Memory Has Been Created | Scientific American

We learn from our personal interaction with the world, and our memories of those experiences help guide our behaviors. Experience and memory are inexorably linked, or at least they seemed to be before a recent reporton the formation of completely artificial memories. Using laboratory animals, investigators reverse engineered a specific natural memory by mapped the brain circuits underlying its formation. They then “trained” another animal by stimulating brain cells in the pattern of the natural memory. Doing so created an artificial memory that was retained and recalled in a manner indistinguishable from a natural one.

Memories are essential to the sense of identity that emerges from the narrative of personal experience. This study is remarkable because it demonstrates that by manipulating specific circuits in the brain, memories can be separated from that narrative and formed in the complete absence of real experience. The work shows that brain circuits that normally respond to specific experiences can be artificially stimulated and linked together in an artificial memory. That memory can be elicited by the appropriate sensory cues in the real environment. The research provides some fundamental understanding of how memories are formed in the brain and is part of a burgeoning science of memory manipulation that includes the transfer, prosthetic enhancement and erasure of memory. These efforts could have a tremendous impact on a wide range of individuals, from those struggling with memory impairments to those enduring traumatic memories, and they also have broad social and ethical implications.

‘They are together, they are equal’: the agonising choice facing father of conjoined twins | The Guardian

Marieme and Ndeye each have a sticker on their faces: a butterfly for Ndeye, and a green smiley face for her twin sister. They giggle as they take them off and stick them back on; then Ndeye decides it’s their dad’s turn, placing the smiley face over his right eye.

“Ndeye is the lively one, she likes attention, and Marieme is a quieter personality – calm and thoughtful,” said Ibrahima Ndiaye, the twins’ father. “Ndeye is fire and Marieme is ice.”

Their behaviour – and their differences – are typical for three-year-old twins, but Marieme and Ndeye are not typical at all. The sisters are conjoined: they have separate brains, hearts and lungs, but share a liver, bladder and digestive system, and have three kidneys between them.

Ndiaye brought his daughters from Senegal to Great Ormond Street hospital (GOSH) in London at the age of eight months after a desperate search for medical help. Over the past two and a half years, he and the hospital have wrestled with an agonising decision about whether to go ahead with a surgical separation that Marieme would not survive, but that could give Ndeye a chance of a reasonable life. Without a separation, both will almost certainly die.

Maths and tech specialists need Hippocratic oath, says academic | The Guardian

Mathematicians, computer engineers and scientists in related fields should take a Hippocratic oath to protect the public from powerful new technologies under development in laboratories and tech firms, a leading researcher has said.

The ethical pledge would commit scientists to think deeply about the possible applications of their work and compel them to pursue only those that, at the least, do no harm to society.

Hannah Fry, an associate professor in the mathematics of cities at University College London, said an equivalent of the doctor’s oath was crucial given that mathematicians and computer engineers were building the tech thatwould shape society’s future.

Should Chimpanzees Be Considered ‘Persons’? | New York Times

You might be aware that chimpanzees can recognize themselves in a mirror, communicate through sign language, pursue goals creatively and form long-lasting friendships. You might also think that these are the kinds of things that a person can do. However, you might not think of chimpanzees as persons.

The Nonhuman Rights Project does. Since 2013, the group has been working on behalf of two chimpanzees, Kiko and Tommy, currently being held in cages by their “owners” without the company of other chimpanzees. It is asking the courts to rule that Kiko and Tommy have the right to bodily liberty and to order their immediate release into a sanctuary where they can live out the rest of their lives with other chimpanzees.

The problem is that under current United States law, one is either a “person” or a “thing.” There is no third option. If you are a person, you have the capacity for rights, including the right to habeas corpus relief, which protects you from unlawful confinement. If you are a thing, you do not have the capacity for rights. And unfortunately, even though they are sensitive, intelligent, social beings, Kiko and Tommy are considered things under the law.

If God Is Dead, Your Time Is Everything | James Wood, New Yorker

At a recent conference on belief and unbelief hosted by the journal Salmagundi, the novelist and essayist Marilynne Robinson confessed to knowing some good people who are atheists, but lamented that she has yet to hear “the good Atheist position articulated.” She explained, “I cannot engage with an atheism that does not express itself.”

She who hath ears to hear, let her hear. One of the most beautifully succinct expressions of secular faith in our bounded life on earth was provided not long after Christ supposedly conquered death, by Pliny the Elder, who called down “a plague on this mad idea that life is renewed by death!” Pliny argued that belief in an afterlife removes “Nature’s particular boon,” the great blessing of death, and merely makes dying more anguished by adding anxiety about the future to the familiar grief of departure. How much easier, he continues, “for each person to trust in himself,” and for us to assume that death will offer exactly the same “freedom from care” that we experienced before we were born: oblivion.

Japan approves first human-animal embryo experiments | Nature

A Japanese stem-cell scientist is the first to receive government support to create animal embryos that contain human cells and transplant them into surrogate animals since a ban on the practice was overturned earlier this year.

Hiromitsu Nakauchi, who leads teams at the University of Tokyo and Stanford University in California, plans to grow human cells in mouse and rat embryos and then transplant those embryos into surrogate animals. Nakauchi's ultimate goal is to produce animals with organs made of human cells that can, eventually, be transplanted into people.

Until March, Japan explicitly forbid the growth of animal embryos containing human cells beyond 14 days or the transplant of such embryos into a surrogate uterus. That month Japan’s education and science ministry issued new guidelines allowing the creation of human-animal embryos that can be transplanted into surrogate animals and brought to term.

Soon, intelligent machines could help decide whether to keep people in jail. It’s time to prepare | The Star

Fahad Diwan logs in and fills out the details of a person facing a bail hearing. Date of birth. Current charges. Pending charges. Past convictions.

Once his SmartBail program is done, he says, an algorithm trained on a mountain of data will be able to assess whether that suspect is a good candidate for pretrial release. Unlikely to be a flight risk. Unlikely to commit offences. Likely to comply with the conditions of release.

Suspects in custody are “legally innocent people,” said Diwan, 30, who hopes to one day put his software to use in Ontario’s bail courts. “We just want to find a way to make the system better, faster, economical.”

Proponents of this kind of program say machine learning would save time and money by quickly identifying people who should be released, speeding up bail hearings, reducing the number of people in jails and freeing up courts to focus on defendants who should have a full, contested hearing. All that with less bias and without affecting the crime rate.

The Ethics of Zoos with associate professors Dr. Andrew Fenton & Dr. Letitia Meynell

In this episode, Kathryn Sussman talks with Dr. Andrew Fenton and Dr. Letitia Meynell, authors and associate professors of Philosophy at Dalhousie University in Halifax. We learn from them about the ethics behind animal captivity in zoos and the relationship that such institutions create between humans and other animal species. They also reflect upon the ethical ways of displaying animals, particularly exotic animals such as polar bears in zoos far from their natural habitat, and the justifications of doing that.

The experts unravel the differences between zoos and sanctuaries as depending on who the exhibits are built for – human visitors or the animals themselves. They also explain how zoo professionals and zoo associations are now starting to aim towards a transformation, focusing onto the animals’ well-being, giving them a life worth living where their basic needs are met.

Scientists Are Giving Dead Brains New Life. What Could Go Wrong?

A few years ago, a scientist named Nenad Sestan began throwing around an idea for an experiment so obviously insane, so “wild” and “totally out there,” as he put it to me recently, that at first he told almost no one about it: not his wife or kids, not his bosses in Yale’s neuroscience department, not the dean of the university’s medical school.

Like everything Sestan studies, the idea centered on the mammalian brain. More specific, it centered on the tree-shaped neurons that govern speech, motor function and thought — the cells, in short, that make us who we are. In the course of his research, Sestan, an expert in developmental neurobiology, regularly ordered slices of animal and human brain tissue from various brain banks, which shipped the specimens to Yale in coolers full of ice. Sometimes the tissue arrived within three or four hours of the donor’s death. Sometimes it took more than a day. Still, Sestan and his team were able to culture, or grow, active cells from that tissue — tissue that was, for all practical purposes, entirely dead. In the right circumstances, they could actually keep the cells alive for several weeks at a stretch.

When I met with Sestan this spring, at his lab in New Haven, he took great care to stress that he was far from the only scientist to have noticed the phenomenon. “Lots of people knew this,” he said. “Lots and lots.” And yet he seems to have been one of the few to take these findings and push them forward: If you could restore activity to individual post-mortem brain cells, he reasoned to himself, what was to stop you from restoring activity to entire slices of post-mortem brain?

German Ethics Council: Germline editing “not ethically out of the question” | European Scientist

On Monday, the German Ethics Council made public a 230-page report discussing their current position on human genome manipulation and in particular, germline editing. According to the press release published on 9 May, a few days before the report, “germline interventions currently too risky, but not ethically out of the question”.

The council made up of 26 ethicists, legal scholars, scientists, and other experts unanimously agreed there are no compelling philosophical arguments against altering human germlines, which they write is not “in principle, ethically reprehensible.” […]

The World Health Organization called for the establishment of a global registry of gene editing research on humans last March. And many scientists would now agree, genome-editing in the human germline should not be regulated by the scientific community but by law.

All members agreed “ the human germline is not inviolable”, although not all are in favour of the pursuing germline interventions – some are concerned the possible benefits may not outweigh the potential downsides.

[…] The first wave of evolution is expected to offer healing-of-sorts for various individuals such as those profiled in the film with Parkinson’s Disease, paralysis, blindness and more. The next wave is more about general usage.

Of course, who would deny any person suffering from neurological disorders the ability to possess a better quality of life through brain implants? But when such technology is beginning to be touted via interviews in this documentary as that which will be able to help you jump higher, run faster, rid oneself of this habit or that, or that annoying personality trait or another via programming, we could be teetering on some very shaky moral and spiritual ground.

A war made me realize: The world needs biomedical engineers | Zahra Moussavi

It was a sunny and pleasant spring day in Dezful, a small city in the south part of Iran. There were not many people on the street but I remember a young teenager pedalling slowly on his bike. I remember him because a moment later he was decapitated by a piece of metal when an Iraqi missile hit the neighbourhood.

His headless body pedalled for a while before falling to the ground. Everything in that moment registered in my brain like a scene in slow motion.

In shock, all I was thinking was: “Wow! How can the body balance without the brain? The body’s motion must have also been programmed in the spinal cord!”

It was spring of 1981 and I was 20 at the time, a second year university student with no background in biology or human physiology. A year earlier, I wanted to become a nuclear physicist and work on a Nobel Prize winning project. Then the war between Iran and Iraq started and the universities closed. I went to the Red Cross and to hospitals to learn first aid and then to the fronts to help with the war casualties.

The war scenes — and particularly the teenage cyclist on that particular day — made me decide to become a biomedical engineer.

AI MIT CSAIL’s AI can predict the onset of breast cancer 5 years in advance

Breast cancer is the second leading cancer-related cause of death among women in the U.S. It’s estimated that in 2015, 232,000 women were diagnosed with the disease and approximately 40,000 died from it. And while exams like mammography have come into wide practice — in 2014, over 39 million breast cancer screenings were performed in the U.S. alone — they’re not always reliable. About 10% to 15% of women who undergo a mammogram are asked to return following an inconclusive analysis.

Fortunately, with the help of AI, scientists at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and Massachusetts General Hospital are making steps toward more consistent and reliable screening procedures. In a newly published paper in the journal Radiology, they describe a machine learning model that can predict from a mammogram if a patient is likely to develop breast cancer as many as five years in the future.

Should fentanyl dealers be charged with manslaughter if their customers die? | CBC News

The Sarnia, Ont., case of a drug dealer charged with manslaughter after a customer died from taking cocaine laced with fentanyl is raising questions about the legal and moral implications of such charges. 

As the opioid crisis in Canada deepens, the defence lawyer who represented the Sarnia drug dealer thinks there will be more such charges. 

In 2017, a drug dealer sold cocaine laced with fentanyl to someone who died of an overdose. The dealer was charged with trafficking and manslaughter, and this week, she pleaded guilty to the lesser charge of criminal negligence causing death.

For people with dementia, a fight for the right to die | MacLean's

Minister of Health Ginette Petitpas Taylor speaks outside the House of Commons, in Ottawa on Thursday, Nov. 30, 2017., about medical assistance in dying (Adrian Wyld/CP)

Ron Posno was diagnosed with mild cognitive impairment—a precursor to dementia—in 2016, and soon after, the London, Ont., resident re-wrote his will. He already had a Do Not Resuscitate order in place, and to this he added instructions for the niece who was his substitute decision maker that at a specific point in the progress of his illness, she was to seek medical assistance in dying on his behalf.

The eight conditions that Posno identified as signalling the proper time for his death are like a photographic negative that also reveals what he considers a life worth living. When I am unable to recognize and respond to family and friends; when I frequently experience hallucinations, paranoia or acute depression; when I become routinely incontinent; when I am unable to eat, clean or dress myself without assistance: that is when I want it to be over.

But then Posno’s niece, a lawyer in Toronto, informed him that an advance request like this for medical assistance in dying (MAID) was against the law and she would have no ability to act on it once he could no longer consent.

Posno had assumed that this request was basically an extension of his DNR: a statement of his desires for medical treatment in a given set of circumstances. He found it incomprehensible that he could legally state that he did not want CPR and the instruction would be followed if he were unconscious with a DNR in place, but in the face of an illness that would eventually render him unable to provide informed consent, he couldn’t request MAID on behalf of a carefully delineated future version of himself.

SCOTUS LGBT Discrimination Case Will Test Conservative Commitment to Textualism | Verdict

Last week, the Supreme Court agreed to review three lower court decisions posing the important question whether Title VII of the Civil Rights Act of 1964—which makes it unlawful for an employer or prospective employer “to discriminate against any individual . . . because of such individual’s . . . sex”—thereby forbids discrimination on the basis of sexual orientation and gender identity. There is little doubt that few if any of the members of the Congress that originally enacted the statutory language would have thought it had that effect.

However, as the late Justice Antonin Scalia wrote for the Court in a 1998 Title VII case that applied the statute’s sex discrimination prohibition to other circumstances that its drafters likely did not envision, “it is ultimately the provisions of our laws rather than the principal concerns of our legislators by which we are governed.” And there are straightforward reasons to think that discrimination based on sexual orientation or gender identity is sex discrimination.

The pending Title VII cases thus pose a test for the Court’s conservative majority. At one point or another and to varying degrees, all of the Court’s conservatives have embraced some version of the so-called textualist approach to statutory interpretation epitomized by Justice Scalia’s observation in the 1998 case, Oncale v. Sundowner Offshore Services, Inc. If they keep faith with their textualist commitment, they will rule in favor of the plaintiffs.

Decoded Brain Signals Could Give Voiceless People A Way To Talk | NPR

Scientists have found a way to transform brain signals into spoken words and sentences.

The approach could someday help people who have lost the ability to speak or gesture, a team from the University of California, San Francisco reported Wednesday in the journal Nature.

"Finding a way to restore speech is one of the great challenges in neurosciences," says Dr. Leigh Hochberg, a professor of engineering at Brown University who wasn't associated with the study. "This is a really exciting new contribution to the field."
