A large proportion of patients seeking help for urinary tract infections are being misdiagnosed – and even told their problem is psychological, say researchers
A test that is routinely used by doctors to diagnose urinary tract infections wrongly gives a negative result in a fifth of cases, scientists have found.
The findings imply that a large proportion of women who seek medical help for UTIs such as cystitis are being misdiagnosed, with some being told their problem is psychological. Many women with severe symptoms are also likely to have been refused antibiotics.Continue reading...

Smashed mastodon bones show humans arrived over 100,000 years earlier than previously thought say researchers, although other experts are sceptical
The history of the people of America, a story that dates back to the last ice age, has been upended by the battered bones of a mastodon found under a freeway construction site in California.
Archaeological sites in North America have led most researchers to believe that the continent was first reached by humans like us, Homo sapiens, about 15,000 years ago. But inspection of the broken mastodon bones, and large stones lying with them, point to a radical new date for the arrival of ancient humans. If the claim stands up, humans arrived in the New World 130,000 years ago.Continue reading...

Treatments approved by David Cameron’s scheme were not worth money, extended life very little and often had adverse side-effects, study finds
The Cancer Drugs Fund, set up by the government to pay for expensive medicines that the NHS would not normally finance, failed to benefit patients and may have resulted in some of them suffering unnecessarily from toxic side-effects, experts say.
An analysis in a leading cancer journal has found that the fund paid out £1.27bn from 2010 to 2016 – an amount that would have paid for an entire year of mainstream cancer drugs for the NHS.Continue reading...

Mandibulates, a group that includes crustaceans and insects, show huge diversity – Tokummia katalepsis could be the missing link that explains why
A fossilised ancient creature boasting huge pincers resembling can-openers, a hinged two-piece shell and more than 50 pairs of legs has been discovered, shedding light on the evolutionary past of a huge and diverse group of animals.
Researchers say the creature, thought to have lived about 507 million years ago during the Cambrian period, offers insights into the early body plan of mandibulates – a group that encompasses creatures including millipedes, crabs and ants. The group takes its name from the presence of mouth parts known as mandibles, which the animals use to help hold or eat food.Continue reading...

A new systematic review of existing studies suggests it will reduce smoking, but long-term impacts of standardised cigarette packaging are still unknown
Standardised packaging for cigarettes was first introduced in the UK in May last year. Tobacco companies were forced to stop producing branded packs, but were still allowed to sell off existing stock. From 21 May 2017, that must stop too. Fancy, colourful, unique branding on cigarette packets will be completely replaced by uniform olive green boxes, larger health warnings, and brand names written in the same size and font, regardless of make.
These changes are the latest in a long line of regulations designed to make smoking less appealing, particularly to teenagers – two-thirds of long-term smokers will start before they’re 18 years old. But is there evidence to support the effectiveness of such packaging?Continue reading...

It’s a sensational claim, but a group of researchers believe that they may have found evidence that will rewrite the history of human arrival in North America. The scientists believe that smashed mastodon bones found under a freeway construction site in California indicate that humans arrived over 100,000 years earlier than previously thought. To say that other experts are sceptical, however, would be to understate the situation somewhat. “They are going to face a shitstorm,” said one scientist who preferred not to be named. For my (admittedly limited) money, however, the two biggest stories this week were advances in cancer screening and care for premature babies. The first is a ‘liquid biopsy’, a DNA-based test that in a major lung cancer trial was able to spot cancer recurrence up to a year before conventional scans. But to me, the most impressive breakthrough this week is the artificial womb intended to help premature babies. It has been shown to keep that premature lambs alive and growing for four weeks. Doctors are hoping that this could act as a bridge between the womb and the outside world for the the most fragile newborns – those born between 23 and 28 weeks’ gestation.Continue reading...

‘Liquid biopsy’ diagnosed cancer recurrence up to a year before CT scans are able to in major lung cancer trial, and could buy crucial time for doctors
A revolutionary blood test has been shown to diagnose the recurrence of cancer up to a year in advance of conventional scans in a major lung cancer trial.
The test, known as a liquid biopsy, could buy crucial time for doctors by indicating that cancer is growing in the body when tumours are not yet detectable on CT scans and long before the patient becomes aware of physical symptoms.Continue reading...

Lambs born at equivalent of 23 weeks human gestation kept alive and developing in advance could transform outlook for very premature babies
An artificial womb designed to support critically premature babies has been demonstrated successfully in animals for the first time, in an advance that could transform the lives of the most fragile newborns.
Lambs born at the equivalent of 23 weeks in a human pregnancy were kept alive and appeared to develop normally while floating inside the transparent, womb-like vessel for four weeks after birth. Doctors said that the pioneering approach could radically improve outcomes for babies born so early that they cannot breathe, feed or fight infection without medical help.Continue reading...

Tranexamic acid could save the lives of a third of women who die in childbirth from excessive bleeding, which kills 100,000 a year
A cheap and widely available drug could save the lives of thousands of women who die in childbirth from excessive bleeding, one of the main killers of women worldwide.
The drug, tranexamic acid, is available over the counter in the UK to women suffering from heavy periods. In Japan and the far east, it is used as a skin whitener. But now a very large study of 20,000 women in 21 countries has shown it can stop a third of cases of bleeding to death after giving birth.Continue reading...

Mathematical analysis reveals that for players with good control, using an unorthodox underarm technique gives better odds of scoring
It might invite ridicule, but it gets results. A scientific analysis has concluded that using a “granny style” underarm technique is the optimal way to take a free throw in basketball.
Adopting the unorthodox strategy could result in marginal gains for professional players, the research suggests. And, as sporting doctrine goes, marginal gains can lead to remarkable results.Continue reading...

Wax moth larvae are usually bred as fish bait, but a chance discovery has revealed their taste for plastic – which could be used to beat polluting plastic
For caterpillars that are bred as premium fish bait, it must rank as a better life. Rather than dangling on the end of a hook and wondering what comes next, the grubs are set to join the war on plastic waste.
The larvae of wax moths are sold as delicious snacks for chub, carp and catfish, but in the wild the worms live on beeswax, making them the scourge of beekeepers across Europe.

Support for ‘machine learning’ depended on what it would be used for, with mass unemployment among main fears
Apart from fears of mass unemployment, accidents with machinery, restrictions on freedom, increased economic inequality and a devalued human experience, the public are broadly optimistic about the arrival of artificial intelligence, according to one of the first surveys of British opinions about the technology.
Research by the polling firm Ipsos Mori found nearly a third of people believe the risks of “machine learning” outweigh the benefits, while 36% believe the risks and benefits are balanced.Continue reading...

In a week in which we discovered that a rather large river has disappeared (hat tip to anthropogenic climate change, you old rogue!) and that aliens so far seem to desire no encounters with us, let alone close ones, it might seem tempting to turn on, tune in and drop out. Certainly the brain scans showing the first evidence of a ‘heightened state of consciousness’ from psychedelic drugs might make this seem a reasonable alternative to facing the tactical voting and alternative fact awfulness currently everywhere. You could always go on a healthy March for Science this weekend instead, though (coming to a city in a country near you!). Or – and this is my my preferred option – you could spend your time marvelling at the incredible adaptability of naked mole rats, whose ability to survive without oxygen was revealed this week. If your weird threshold is particularly high you could give yourself a further treat and spend time looking with revolted fascination at the first living giant shipworm, discovered in the Philippines. It’s very, um. Yes. Um. You’re welcome.Continue reading...

The Cassini spacecraft and its dramatic dive towards Saturn have been in the news this week, but the human Cassini is no less memorable
As a historian of science, when I scroll through my Twitter timeline and see mentions of Cassini, my thoughts tend to go not to the spacecraft that is, at the time of writing, somewhere between Saturn’s rings and the planet itself. Rather, they turn to Cassini I, II, III and IV, the 17th and 18th-century dynasty of Paris Observatory directors. With the word Saturn appearing alongside, I fix on Cassini I, Giovanni Domenico (or, after he moved to France, Jean-Dominique) Cassini.
Giovanni Domenico Cassini was the first director of the observatory founded by Louis XIV and, among much else, he discovered two of Saturn’s moons, the planet’s equatorial belt and a division in its rings. This last has been named the Cassini Division in his honour. Thus the Cassini Spacecraft has imaged the Cassini Division that was first depicted by Cassini I. It can just be seen in the image at the top, which was published in 1676 in the Philosophical Transactions of the Royal Society.Continue reading...

Despite sensational news reports and pop-culture portrayals, the notion that any human has, or even could have, a 100% reliable memory is far from certain
Every now and then, you see news reports of people with incredible memories, able to recall every single thing from their life at a moment’s notice. Initially, it may sound like an incredibly useful ability. No more searching for your car keys that you had in your hand minutes ago, no more desperately stalling for time as you flounder to remember the name of the casual acquaintance who’s just said hello to you, no more taking notes at all. Why would you need to? It’s no wonder it pops up often in pop culture.
Indeed, there are many people who can demonstrate incredible memory prowess, having trained their memories to be as efficient and thorough as possible via useful and approved techniques, in order to compete in memory sports, which are an actual thing. Clearly, for some people at least, there is potential to greatly boost the brain’s ability to store and recall information to well above average levels. Ben Carson even claimed to be able to induce this with a simple bit of surgery (which is utterly wrong)Continue reading...

A recent meta-study suggests that regular exercise improves the functioning of the brain in people aged 50 and over. How does that work, and is it even surprising?
A recently-published study has provided strong evidence that regular exercise is very beneficial for the health and functioning of the brain in the over 50s. To many scientists, this is just confirming what we already knew. But for others, this may come as a surprise to hear.
Who can blame them? Crude portrayals and stereotypes from mainstream entertainment, most obviously bawdy American comedies of the 80s, give the impression there is some sort clear divide between enjoying physical or intellectual activities, as if these things are incompatible. They present a world where you can either be a big, lumbering, strong-but-monosyllabic sports star, or a feeble, pasty, asthmatic book-and-gadget-loving genius.Continue reading...

Scientists can’t turn their backs on the engagement of mass-media, but when it comes to inaccurate and sensational headlines, do the ends justify the means?
“The public is mostly made of people who just don’t care. The media know they don’t understand the science and they don’t want to learn about it either.” An established scientist bitterly confesses to me his experiences with public outreach, via news media. He is red-faced and his voice is getting louder. “I know you have good intentions, but when you’ve been in the field for as long as me you’ll realise that we can’t win – the media will always take your words and turn them against you. All they care about is public entertainment. Accuracy? Forget it!”
We’ve been talking for ten minutes, and it has become increasingly tense. The frustration is obvious: here is someone who loves his work and really wants to tell people about it. Yet he no longer engages with the press office at his institution, not if he can avoid it. He has learnt the hard way that if you speak to the media, what you say is too often misquoted and misunderstood. The science, the real message, is lost to sensationalism.Continue reading...

The British Isles split from Europe several thousand years ago. Now, maritime archaeology is revealing a lost landscape on the seafloor
The British Isles separated from the European continent approximately 8,000 years ago. For this Brexit there was no referendum or bus, no Leavers or Remainers, nor was it hard or soft. This was a watery Brexit as rising sea levels filled the Channel and created the North Sea. Maritime archaeology is revealing this submerged landscape that once connected the continent to Britain.
Earth is a dynamic planet that is constantly changing. Going back far enough in time, Britain has been separated from the continent several times as sea levels changed. However, for the study of Homo sapiens it is the change at end of the Pleistocene and the start of the Holocene epoch 11,700 years ago that is most interesting.Continue reading...

Psychology research shows people mistrust those who make moral decisions by calculating costs and benefits – like computers do
Technologies built on artificial intelligence are revolutionising human life. As these machines become increasingly integrated in our daily lives, the decisions they face will go beyond the merely pragmatic, and extend into the ethical. When faced with an unavoidable accident, should a self-driving car protect its passengers or seek to minimise overall lives lost? Should a drone strike a group of terrorists planning an attack, even if civilian casualties will occur? As artificially intelligent machines become more autonomous, these questions are impossible to ignore.
There are good arguments for why some ethical decisions ought to be left to computers—unlike human beings, machines are not led astray by cognitive biases, do not experience fatigue, and do not feel hatred toward an enemy. An ethical AI could, in principle, be programmed to reflect the values and rules of an ideal moral agent. And free from human limitations, such machines could even be said to make better moral decisions than us. Yet the notion that a machine might be given free reign over moral decision-making seems distressing to many—so much so that, for some, their use poses a fundamental threat to human dignity. Why are we so reluctant to trust machines when it comes to making moral decisions? Psychology research provides a clue: we seem to have a fundamental mistrust of individuals who make moral decisions by calculating costs and benefits – like computers do.Continue reading...

Empathy requires mental gymnastics at the best of times. Empathy for whole categories of people requires Olympic-level skills
It is usually seen as a depressing paradox about human beings that we find it easier to sympathise with one person’s suffering than with that of thousands: Stalin probably never really said “one death is a tragedy, a million deaths is a statistic” – but he was right all the same. It’s not much of a paradox, though. It makes sense: each of us has access to only one set of thoughts and emotions – our own – so we’re obliged to relate to others by analogy, working on the assumption that they feel pain and joy like we do. (As philosophers enjoy pointing out, you can’t truly know that your family and friends aren’t just meaty robots, with no inner life at all.) And it’s obviously easier to draw an analogy between yourself and one other person, as opposed to “the population of Somalia” or “all victims of domestic violence”, let alone those killed in the future by global warming, who aren’t necessarily even born yet. Empathy requires mental gymnastics at the best of times. Empathy for whole categories of people requires Olympic-level skills, and most of us aren’t up to it.
But there’s an intriguingly easy way to induce compassion for groups, according to a new study by the psychologist Kurt Gray and colleagues, published in the Journal Of Experimental Psychology and reported by Vox. It makes a difference, they found, whether you say “a group of 50 refugees” (for example) versus “50 refugees in a group”. The first phrasing focuses on the group, not its members, with the result that we think of those members as less capable of rich inner experience – and less human, if we’re honest – than ourselves. The latter phrasing focuses on the members, rather than the group. That linguistic switch proved sufficient for participants in the study to treat them as fully human, and fully deserving of compassion.Continue reading...

Sun, 23 Apr 2017 06:00:05 GMT2017-04-23T06:00:05ZBritish scientists are exploring ways to use the steel industry’s waste to capture carbon dioxide in the atmosphere
The Industrial Revolution left a deep mark on our world. Its dawning saw the start of the widespread burning of coal for factories and steam engines and, as a result, the beginning of significant outputs of carbon dioxide into the atmosphere. Our climate is now warming noticeably as these emissions have accumulated across the planet.
The British landscape has also been changed dramatically. In particular, the countryside is now peppered with piles of slag left over from old steel mills. Landscaping these piles of industrial waste has required major efforts by local authorities in recent decades.Continue reading...

As linguists celebrate English Language Day and Shakespeare’s birthday, what does the ever-changing way we speak reveal about us?
It is a division as entrenched and as bitter as the split between Brexit backers and EU Remainers – though in this case, the issue is truly personal. Do you pronounce the word “scone” to rhyme with “cone”, or to rhyme with “gone”?
To those in the latter group, it is a posh affectation to use a long vowel for this staple item of afternoon tea. By contrast, those in the former group believe they are merely following a logical extension of the pronunciation of the word cone by adding an s as a prefix.Continue reading...

March for Science organisers hope the mobilising thousands around the world can help restore science to its rightful place. But marching may not be enough
The placards are made, the speeches prepared. On Saturday, crowds in their thousands are expected at 500 marches in more than 35 countries to remind the world, and its many politicians, that society cannot thrive without science. It will be the largest show of solidarity for science the globe has ever seen.
Arranged to coincide with Earth Day, the anniversary of the modern environmental movement, organisers hope that the mobilisation of so many can help restore science to what they consider to be its rightful place. But despite healthy support for the events – more than 100 professional societies and organisations have endorsed them – marches alone will not be enough, according to researchers who study protest movements.

In the early 1970s, a short article by a little-known US scholar reported the discovery of an ancient road near the site of Gordion, the capital city of the ancient kingdom of Phrygia. This article, and his own chance encounter on a family picnic with a batch of undocumented Roman milestones next to a stretch of Roman road west of the modern Turkish capital, Ankara, inspired the archaeologist David French, who has died aged 83, to start the project that occupied him for the rest of his life. This was a comprehensive study, based on field work which took him to every corner of Turkey, of all aspects of the Roman roads of Asia Minor: milestones, road surfaces, bridges, the imperial road stations, and military installations.
He combined classical training with archaeological experience and an intimate knowledge of Turkey to acquire a more profound understanding of the topographical history of Anatolia – Asiatic Turkey – than any other scholar past or present. His passion for roads and routes extended from the Roman empire back to its Hittite and Persian predecessors and forward to the Ottoman period. At the start of his project, about 450 milestones were known from Asia Minor; by 2016, his discoveries had raised this number to more than 1,200. The research, carried out single-handed in the company of a series of Turkish government representatives, was a perfect match for his skills and character.Continue reading...

The effects of psychedelic drugs can lead to colours seeming more vivid and things seeming more beautiful, finds Rosalind Stone
My favourite trip was in Richmond Park in 2014. I took 100 micrograms of 1P-LSD, a designer LSD analogue which was legal in the UK until May 2016. The acid come-up starts in your throat: warmth spreads through you like syrup. Words will be more fun to say. Dust, sunbeams and the lint on your sleeves take on a faint, bluish fizz, or is it a whizz?Continue reading...

Trump is the worst thing that could have happened to the planet. That’s all the more reason to fight on - and celebrate even the smallest successes
There is no upside to the Trump presidency. To be in DC – I’ve come for Saturday’s giant climate march – is to be reminded up close what all Americans have known for months: we’ve put the country in the hands of a man completely unequal to the task. A man so cluelessly over his head that he keeps telling reporters he’s in over his head.
But if you want a few grayish linings to the dark-orange cloud, you can find them. In fact, the last few days have given those of us in the climate fight a few glimmers of light.Continue reading...
Fri, 28 Apr 2017 12:15:56 GMT2017-04-28T12:15:56ZAntidotes to these dangerous, destructive synthetic drugs are desperately needed. But the government is standing in the way of their development
Last year I wrote to the health and home secretaries with suggestions on how antidotes for spice could be developed. Their replies revealed a complete lack of appreciation of the magnitude of the synthetic cannabinoid problem and lack of interest in the idea of an antidote.
Spice-induced “zombie” outbreaks in New York and in Manchester have hit the headlines in the past year. Use of these new damaging and powerful forms of synthetic cannabinoids is rife in our prisons and by homeless people, with estimates of up to 50 deaths last year. They can produce extremely strong psychotic states often with very violent behaviour. Sometimes a frozen unconscious state results. Either of these outcomes are health emergencies that consume vast amounts of police, prison officer and health professionals time, and so waste a huge amount of public money.Continue reading...

Encounters with new worlds and new life will present religions with the ultimate theological conundrum. But they will adapt, as they have done before
About two decades ago, it was quite uncertain whether stars other than our own sun even hosted their own planets. However, according to Nasa, the latest count of confirmed exoplanets stands at around 3,500 – and at least six of them are potential Earths. This count will definitely go up and many researchers believe that the advancement of technology will enable humans to discover some form of life on another planet in the coming years.Continue reading...

Nearly half of LGBTIQ Australians hide their sexual identity at work, with many experiencing homophobic abuse. It’s time to do better
In 2015 a US survey found that LGBTIQ scientists felt more accepted in their workplaces than their peers in other professions did. The Queer in Stem survey, published in the Journal of Homosexuality, surveyed 1,400 LGBTIQ workers in science, technology, engineering and mathematics. They found respondents in scientific fields that had a high proportion of women were more likely to be out to their colleagues than those who worked in male-intensive disciplines.
This is heartening news as it’s not necessarily that way in most Australian workplaces. Last year a report found that nearly half of LGBTIQ Australians hide their sexual identity at work. The report also found six in 10 LGBTIQ people have experienced verbal homophobic abuse in the workplace, while two in 10 have experienced physical violence.Continue reading...

Caterpillars that can munch up plastic bags have just been identified, fuelling excited speculation that this could one day eliminate global pollution from plastic waste. The chance discovery, initially made by a scientist and amateur beekeeper whose plastic bag had been eaten through by the moth caterpillars, was reported this week by researchers at Cambridge University and the Spanish National Research Council.Continue reading...
Sun, 23 Apr 2017 14:04:31 GMT2017-04-23T14:04:31ZWe all love science when it’s making life better, longer and easier. It’s a much harder sell when it points to inconvenient truths about our way of life
There is an old joke about being able to tell an extroverted scientist: instead of staring at their shoes when they talk to you, they stare at yours. This is no longer true. Scientists are the new rock stars. Tonight Einstein gets the full soft-focus Crown-style treatment as National Geographic launches a 10-part series about the man described by the actor Geoffrey Rush, who portrays him in Genius, as a “stud-muffin theoretical physicist”.

$100m spent and still there is no sign of extraterrestrials
Very sad news for fans of aliens (should they exist). After more than a year of listening for signals, astronomers working on the $100m Breakthrough Listen project, funded by Silicon Valley billionaire Yuri Milner, have found no evidence of extraterrestrials. The only “intelligent signals” came via satellites, mobile phones and other “earthly devices”.
The good news is that the “ET phone home” scene packs an even greater punch now that we know about all those strong mobile signals. A tiny negative: $100m is rather a lot for what sounds like the equivalent of holding your phone in the air and yelling: “No UFOs as yet, but I’ve got three bars.”Continue reading...

Some say that the March for Science risks making science political. But it already is – and not addressing that is a problem
Tens of thousands of scientists and supporters of science are pouring into the streets of Washington DC and other cities around the world on Saturday in a massive March for Science, aimed at highlighting the importance of science to society and the need for basing government policies on evidence.
But some thoughtful people, including some very distinguished scientists, have argued that the March is a mistake – that, by marching, scientists will create the impression that they are just one more interest group and, worse, will be seen as “politicizing science”. I beg to differ. Those criticisms will surely continue to be hurled at the March, but I believe they are off the mark.Continue reading...

When politicians smear science, real people get hurt. I’m marching because we must fight for communities who are harmed by bad science policy
I’m marching for science today because I’m mad. Yes, I’m a mad scientist. I became a scientist because I wanted to help people. In my career I’ve researched gene therapy, how to engineer new antibiotics and how to make better cancer drugs. But now what I do and care about has come under attack. I’m mad at politicians for hijacking science for their own selfish interests.
I know that many people just love debating whether science should be political or not. But personally I’m not really too interested in spinning my wheels in this pyrrhic war. Science has always been political ever since we first used it to show that the Earth orbits the sun. And right now, we haven’t any time to waste.Continue reading...

Nuclear tensions appear to be mounting again amidst political upheaval. So if the event of nuclear war, where should you head?
We are safer now than perhaps any time in our history. Let’s take the cheery topic of violent death, for example. In most of the world, murder rates are falling along with other violent crimes. A recent UN study reported that homicide rates in North America, Europe and Asia have been declining for last 15 years, and wars have also become less deadly when compared to conflicts in the 20th century. Even contemporary atrocities in the Middle East do not compare to the industrial genocide of Stalin, Mao, or Hitler. Research by the Early Warning Project for example, has shown a clear decline in mass killings in wars and conflicts since 1992.Continue reading...

A former analyst with the US Department of Defence is on the trail of an astronomical ‘cold case’ – an unexplained signal that some believe could have come from extraterrestrials
Way back in 1977 something amazing happened (apart from the release of Star Wars obviously). Astronomer Jerry Ehman was using the Ohio State University’s Big Ear radio telescope to sweep the sky for possible signals from extraterrestrial civilisations. He found something.
While pointing towards a grouping of stars called Chi Sagittarii on 15 August, he received a powerful blast of radio waves that lasted for 72 seconds. He circled it on the readout and wrote: “Wow!”Continue reading...
Mon, 28 Nov 2016 15:02:20 GMT2016-11-28T15:02:20ZThe term ‘snowflake’ has been thrown around with abandon in the wake of Brexit and the US election, usually to express generic disdain for young people. How can we neutralise its power – and is it a bad metaphor anyway?Between the immediate aftermath of Brexit and the US presidential election, one insult began to seem inescapable, mostly lobbed from the right to the left: “snowflake.” Independent MEP Janice Atkinson, who was expelled from Ukip over allegations of expenses fraud, wrote a piece for the Huffington Post decrying the “wet, teary and quite frankly ludicrous outpouring of grief emails” she had received post-referendum as “snowflake nonsense”. The far-right news site Breitbart, whose executive chairman Stephen Bannon is now Donald Trump’s chief strategist, threw it around with abandon, using it as a scattershot insult against journalists, celebrities and millennials who objected to Trump’s inflammatory rhetoric; its UK site used it last week to criticise a proposed “class liberation officer” at an Oxford college who would provide more support for working-class students.On an episode of his long-running podcast in August, Bret Easton Ellis discussed the criticism of a lascivious LA Weekly story about the pop star Sky Ferreira with a furious riposte to what he calls “little snowflake justice warriors”: “Oh, little snowflakes, when did you all become grandmothers and society matrons, clutching your pearls in horror at someone who has an opinion about something, a way of expressing themselves that’s not the mirror image of yours, you snivelling little weak-ass narcissists?” Continue reading...[...]

First ever observed case of ‘river piracy’ saw the Slims river disappear as intense glacier melt suddenly diverted its flow into another watercourse
An immense river that flowed from one of Canada’s largest glaciers vanished over the course of four days last year, scientists have reported, in an unsettling illustration of how global warming dramatically changes the world’s geography.
The abrupt and unexpected disappearance of the Slims river, which spanned up to 150 metres at its widest points, is the first observed case of “river piracy”, in which the flow of one river is suddenly diverted into another.Continue reading...

Study records what appears to be the first evidence for mind-opening state experienced by users of LSD, ketamine and psilocybin
Brain scans have revealed the first evidence for what appears to be a heightened state of consciousness in people who took psychedelic drugs in the name of science.
Healthy volunteers who received LSD, ketamine or psilocybin, a compound found in magic mushrooms, were found to have more random brain activity than normal while under the influence, according to a study into the effects of the drugs.
