David Suzuki: ‘It’s very, very late and urgent’ to take climate action if we want to prevent human extinction
Astronomers say it’s time to start taking the search for E.T. seriously
Science News reports: Long an underfunded, fringe field of science, the search for extraterrestrial intelligence may be ready to go mainstream. Astronomer Jason Wright is determined to see that happen. At a meeting in Seattle of the American Astronomical Society in January, Wright convened “a little ragtag group in a tiny room” to plot a course for putting the scientific field, known as SETI, on NASA’s agenda. The group is writing a series of papers arguing that scientists should be…
Inside the struggle to define life
Ian Sample writes: All the brain cells of life on Earth still cannot explain life on Earth. Its most intelligent species has uncovered the building blocks of matter, read countless genomes and watched spacetime quiver as black holes collide. It understands much of how living creatures work, but not how they came to be. There is no agreement, even, on what life is. The conundrum of life is so fundamental that to solve it would rank among the most important…
What animals are thinking and feeling, and why it should matter
Chinese scientist who claimed to make genetically edited babies is kept under guard
The New York Times reports: The Chinese scientist who shocked the world by claiming that he had created the first genetically edited babies is sequestered in a small university guesthouse in the southern city of Shenzhen, where he remains under guard by a dozen unidentified men. The sighting of the scientist, He Jiankui, this week was the first since he appeared at a conference in Hong Kong in late November and defended his actions. For the past few weeks, rumors…
Hume believed we were nothing more or less than human
Julian Baggini writes: Socrates died by drinking hemlock, condemned to death by the people of Athens. Albert Camus met his end in a car that wrapped itself around a tree at high speed. Nietzsche collapsed into insanity after weeping over a beaten horse. Posterity loves a tragic end, which is one reason why the cult of David Hume, arguably the greatest philosopher the West has ever produced, never took off. While Hume was lying aged 65 on his deathbed at…
The discovery of vast populations of subsurface microbial beings is shaking up what we think we know about life
JoAnna Klein writes: At the surface, boiling water kills off most life. But Geogemma barossii is a living thing from another world, deep within our very own. Boiling water — 212 degrees Fahrenheit — would be practically freezing for this creature, which thrives at temperatures around 250 degrees Fahrenheit. No other organism on the planet is known to be able to live at such extreme heat. But it’s just one of many mysterious microbes living in a massive subterranean habitat…
Russians interacted with at least 14 Trump associates during the campaign and transition
The Washington Post reports: The Russian ambassador. A deputy prime minister. A pop star, a weightlifter, a lawyer, a Soviet army veteran with alleged intelligence ties. Again and again and again, over the course of Donald Trump’s 18-month campaign for the presidency, Russian citizens made contact with his closest family and friends, as well as figures on the periphery of his orbit. Some offered to help his campaign and his real estate business. Some offered dirt on his Democratic opponent….
If dying could be sweet
When former presidents or other famous people die, the news of such events is always dominated by recollections of their lives. Generally we learn only the most abbreviated details of the circumstances in which life came to an end. The final days of George H W Bush’s life were unusual in that they were shared with his lifelong friend James Baker and other friends and family members who then graciously provided the New York Times with an account that conveys…
The insect apocalypse is here. What does it mean for the rest of life on Earth?
Brooke Jarvis reports: Sune Boye Riis was on a bike ride with his youngest son, enjoying the sun slanting over the fields and woodlands near their home north of Copenhagen, when it suddenly occurred to him that something about the experience was amiss. Specifically, something was missing. It was summer. He was out in the country, moving fast. But strangely, he wasn’t eating any bugs. For a moment, Riis was transported to his childhood on the Danish island of Lolland,…
Humanity is destroying life on Earth
The Guardian reports: Humanity has wiped out 60% of mammals, birds, fish and reptiles since 1970, leading the world’s foremost experts to warn that the annihilation of wildlife is now an emergency that threatens civilisation. The new estimate of the massacre of wildlife is made in a major report produced by WWF and involving 59 scientists from across the globe. It finds that the vast and growing consumption of food and resources by the global population is destroying the…
The rhythm of life
Living in ignorance about our ignorance
Kaidi Wu and David Dunning write: In 1806, entrepreneur Frederic Tudor sailed to the island of Martinique with a precious cargo. He had harvested ice from frozen Massachusetts rivers and expected to make a tidy profit selling it to tropical customers. There was only one problem: the islanders had never seen ice. They had never experienced a cold drink, never tasted a pint of ice cream. Refrigeration was not a celebrated innovation, but an unknown concept. In their eyes, there…
We are more than our brains
Alan Jasanoff writes: Brains are undoubtedly somewhat computer-like – computers, after all, were invented to perform brain-like functions – but brains are also much more than bundles of wiry neurons and the electrical impulses they are famous for propagating. The function of each neuroelectrical signal is to release a little flood of chemicals that helps to stimulate or suppress brain cells, in much the way that chemicals activate or suppress functions such as glucose production by liver cells or immune…
What matters
Owen Flanagan writes: In “The Strange Order of Things” Antonio Damasio promises to explore “one interest and one idea … why and how we emote, feel, use feelings to construct our selves; how feelings assist or undermine our best intentions; why and how our brains interact with the body to support such functions.” Damasio thinks that the cognitive revolution of the last 40 years, which has yielded cognitive science, cognitive neuroscience and artificial intelligence, has been, in fact, too cognitive,…
Have we forgotten how to die?
In a review of seven books on death and dying, Julie-Marie Strange writes: James Turner was twenty-five when his four-year-old daughter Annice died from a lung condition. She died at home with her parents and grandmother; her sleeping siblings were told of her death the next morning. James did everything to soothe Annice’s last days but, never having encountered death before, he didn’t immediately recognize it. He didn’t know what to do or expect and found it hard to discuss…
