‘Over the past 60 years, the population of cephalopods—octopuses, squids, and cuttlefish—has been steadily growing. This is particularly remarkable because many types of marine life have been dying out as carbon levels in the oceans rise, making the water more acidic. So even as numbers of crabs, sea stars, and coral reefs are shrinking, the tentacled creatures of the deep are thriving.
Writing in Current Biology, a large group of marine biologists describe how they discovered this trend. Looking at the past 61 years of fisheries data from all major oceans, they examined numbers of cephalopods that are bycatch, or accidentally caught along with target fish. Using these numbers as a proxy for cephalopod populations as a whole, they discovered a steady increase over the decades, across all cephalopod species. The question is why.
The researchers say it’s likely a function of a cephalopod’s ability to adapt quickly. “These ecologically and commercially important invertebrates may have benefited from a changing ocean environment,” they write. Most cephalopods have very short lifespans and are able to change their behavior very quickly during their lifespans. Indeed, octopuses are tool-users who can learn quickly, leading to many daring escapes from tanks in labs as well as brilliant forms of camouflage at the bottom of the ocean. All these characteristics add up to a set of species who can change on the fly, as their environments are transformed.
If trends continue, cephalopods may be among the species who are poised to survive a mass extinction in the oceans, leading to a future marine ecosystem ruled by tentacles…’

‘…Jake had spent his life respecting the Earth, and he didn’t want his final act to harm it. He was also opposed to the death care industry — a $20 billion-a-year business notorious for preying on people at the lowest points in their lives. It’s an industry increasingly controlled by a single entity called Service Corporation International (SCI), a company with 20,000 employees and a market capitalization of $4 billion.
Jake decided on something different: a natural burial. He wanted to go back to the burial traditions humans embraced for thousands of years, before the development of chemical embalming and steel-lined caskets. There would be no formaldehyde, no coffin, just a simple shroud and a hole in ground.”
…Natural burial is perfectly legal in the United States, but that doesn’t mean it’s easy. Jake’s friends and family couldn’t just dig a hole on his land in Port Angeles and leave him there to rest — although they did think about it, Tristan says. Natural burial requires a cemetery willing to take the body, which can be difficult to find. Because so many cemeteries are owned by SCI, a company that pushes clients to take the full package — embalming, concrete-lined vaults, etc. — there are only a handful of natural cemeteries in all of Washington state…’
Partly, it’s because we have a bewildering array of problems that emerge when we try to get close to others. We seem normal only to those who don’t know us very well. In a wiser, more self-aware society than our own, a standard question on any early dinner date would be: “And how are you crazy?”
Perhaps we have a latent tendency to get furious when someone disagrees with us or can relax only when we are working; perhaps we’re tricky about intimacy after sex or clam up in response to humiliation. Nobody’s perfect. The problem is that before marriage, we rarely delve into our complexities. Whenever casual relationships threaten to reveal our flaws, we blame our partners and call it a day. As for our friends, they don’t care enough to do the hard work of enlightening us. One of the privileges of being on our own is therefore the sincere impression that we are really quite easy to live with.
Our partners are no more self-aware. Naturally, we make a stab at trying to understand them. We visit their families. We look at their photos, we meet their college friends. All this contributes to a sense that we’ve done our homework. We haven’t. Marriage ends up as a hopeful, generous, infinitely kind gamble taken by two people who don’t know yet who they are or who the other might be, binding themselves to a future they cannot conceive of and have carefully avoided investigating…’

‘Few atheists know the Bible as intimately as Dan Barker. Few, after all, can profess to have begun their careers as fundamentalist Christian preachers. Currently co-president of the Freedom from Religion Foundation, an American non-profit organisation, Barker was a self-proclaimed “extremist” for 19 years, until he renounced the faith.
Given how vehemently the 66-year-old now defends a life free of any supernatural authority, I ask him if he regrets the consequences that his Christian ministry may have had on people he would now describe as vulnerable. “Yes, I do regret a lot of it,” he says with candour. “I would counsel people to pray for healing. That’s dangerous. That’s harmful. People die from that. And I acted irresponsibly with my health, because I knew that God was going to take care of me.” This is a window that, once opened, is difficult to close. Barker reels off multiple instances in which he believes that he seriously damaged the lives of his parishioners.
In Arizona, a woman approached him, looking for faith healing to cure her of an illness. The two prayed together and when, inevitably, it did nothing, he said, “Let it be unto you according to your faith” (a reference to a line originally found in Matthew 8:13). “In other words,” Barker says, “it was her fault. She walked out of that meeting not only not healed but feeling chastised. It’s not a kind way to treat another human being.”
In his mid-twenties, he counselled a woman who was struggling with an abusive husband. Barker told her to persevere with him because, as the Bible says, he would eventually see the light. “So I counselled a woman to stay in an abusive relationship, because the Bible says that you are married for life.” What would he say if she approached him with the same problem now? “I would tell her to run for the nearest shelter and get out of there.”
Barker may have left religion behind but he is still a preacher of sorts. His latest book, God: the Most Unpleasant Character in All Fiction, draws on his knowledge of scripture to attack the Bible’s claim to moral authority. If the title sounds familiar, that’s because it’s a phrase that Richard Dawkins uses to introduce the second chapter of The God Delusion. There, he accuses the God of the Old Testament of 19 character flaws, among them jealousy, sadomasochism, caprice and ethnic cleansing. In a foreword to Barker’s book, Dawkins writes that The God Delusion’s reputation for stridency owes much to this one sentence…’

‘The demonstration began on the afternoon of May 21, 1946, at a secret laboratory tucked into a canyon some three miles from Los Alamos, New Mexico, the birthplace of the atom bomb. Louis Slotin, a Canadian physicist, was showing his colleagues how to bring the exposed core of a nuclear weapon nearly to the point of criticality, a tricky operation known as “tickling the dragon’s tail.” The core, sitting by itself on a squat table, looked unremarkable—a hemisphere of dull metal with a nub of plutonium sticking out of its center, the whole thing warm to the touch because of its radioactivity. It had been quickly molded into shape after the bombing of Nagasaki, to be used in another attack on Japan, then reallocated when it turned out not to be needed for the war effort. At that time, Slotin was perhaps the world’s foremost expert on handling dangerous quantities of plutonium. He had helped assemble the first atomic weapon, barely a year earlier…
Slotin’s procedure was simple. He would lower a half-shell of beryllium, called the tamper, over the core, stopping just before it was snugly seated. The tamper would reflect back the neutrons that were shooting off the plutonium, jump-starting a weak and short-lived nuclear chain reaction, on which the physicists could then gather data. Slotin held the tamper in his left hand. In his right hand, he held a long screwdriver, which he planned to wedge between the two components, keeping them apart. As he began the slow and painstaking process of lowering the tamper, one of his colleagues, Raemer Schreiber, turned away to focus on other work, expecting that the experiment would be uninteresting until several more moments had passed. But suddenly he heard a sound behind him: Slotin’s screwdriver had slipped, and the tamper had dropped fully over the core. When Schreiber turned around, he saw a flash of blue light and felt a wave of heat on his face…’

‘Abstract: The annual list of the most common causes of death in the United States, compiled by the Centers for Disease Control and Prevention (CDC), informs public awareness and national research priorities each year. The list is created using death certificates filled out by physicians, funeral directors, medical examiners, and coroners. However, a major limitation of the death certificate is that it relies on assigning an International Classification of Disease (ICD) code to the cause of death.1 As a result, causes of death not associated with an ICD code, such as human and system factors, are not captured. The science of safety has matured to describe how communication breakdowns, diagnostic errors, poor judgment, and inadequate skill can directly result in patient harm and death. We analyzed the scientific literature on medical error to identify its contribution to US deaths in relation to causes listed by the CDC…’

Are We Headed for Thousands of Times the Number of Overdose Deaths?
‘Global media outlets have recently been reporting the appearance of a terrifying new drug, known as W-18, on the streets of Canada, with many suggesting that the substance could be as much as 10,000 times stronger than morphine. However, the truth is that such comparisons are somewhat tenuous, since very little is actually known about how this alarming drug works – a fact that could potentially make it more dangerous than even these sensational reports imply.
Originally developed by scientists at the University of Alberta back in the mid-1980s, W-18 was intended to be a synthetic painkiller that could outperform existing opioid medications such as morphine and oxycodone. The substance was only ever tested on mice, and proved to be so strong that it sent some of the rodents into a five-day coma. However, research on W-18 was never taken any further, so instead of being used to develop new pharmaceuticals for human consumption, the compound went the way of so many other rejected research chemicals and simply disappeared into the abyss of forgotten science – until now.
The first sign of W-18 rearing its ugly head in the guise of a street drug came in August 2015, when police in Calgary busted a shipment of 110 pills thought to contain the prohibited substance fentanyl – itself a synthetic opioid purported to be around 10 times stronger than heroin. Chemical analysis revealed that a small number of these pills actually contained traces of W-18, thought to have been produced in Chinese laboratories. Since then, larger stashes of the substance have been found in other locations across Canada and the U.S., although because W-18 is so rare and unheard of, it has never actually been scheduled as an illegal compound…’
