Nobel prize-winner Steven Weinberg’s history of knowledge covers well trodden ground, barely straying from physics and astronomy“I confess that I find Aristotle frequently tedious, in a way that Plato is not,” writes Steven Weinberg, “but although often wrong Aristotle is not silly, in the way that Plato sometimes is.”It’s a school report to make the philosophers blush, but with his latest book, To Explain the World, Weinberg makes it clear he isn’t out to polish anyone’s pedestal. No, he has turned to the notes and theories from classical Greece to reveal how far our understanding, and investigative techniques, progressed between antiquity and the age of enlightenment. For, as Weinberg argues, while Aristotle prized theories based on mental rumination alone, it was the emergence of the scientific method, rooted in physical experimentation, that has allowed us to discover, explain and harness the laws of nature.

Palaeontologists of the past have fallen for some barely believable fakes. So what to think about ultra-sceptics who still question the existence of dinosaurs?The history of palaeontology is littered with examples of famous frauds and fakes, often with eminent researchers in the field being thoroughly hoodwinked by some fairly shoddy fabrications.One of the most famous is Piltdown Man. Discovered in a gravel pit in Sussex in 1912, a few ancient-looking fragments of a skull and jawbone quickly became hailed as evidence of a very early type of human, perhaps half a million years old. The specimens were named Eoanthropus dawsoni (“Dawson’s dawn man”), after their discoverer, amateur archaeologist Charles Dawson. Continue reading...

Expert cautions that antibiotic-resistant bacteria needs to come under control but says ordinary Americans do not need to worryA “superbug” outbreak made national headlines this week, as up to 179 patients at the UCLA Ronald Reagan medical center in Los Angeles were potentially exposed to “nightmare” bacteria through a pair of specialized gastrointestinal tools. The germs may have been a contributing factor in the deaths of two people, doctors said.Related: Superbug at LA hospital linked to two deaths and 179 potential infections Continue reading...

Much scientific discovery is for the betterment, amusement and curiosity of a lucky few in this world. Those without water, meanwhile, are temporarily forgottenI read the news of the proposed one-way trip to Mars for up to 40 lucky Earthlings with curious fascination. First, I browsed through the 100 candidates who had made the shortlist. Of course there was a Nigerian, a certain Ighodalo whose upbeat personableness came across well in his application video. No matter how bizarre the enterprise, I am always glad to see Nigeria represented. Next, I discovered that to fund the mission, both the journey out and the first years on the red planet will be turned into a reality show: perhaps Big Brother Mars, The Only Way is Martian, The Real Housewives of the Athabasca Valles. I could go on for a whole episode of Star Trek.What struck me as I surfed through the profiles of shortlisted candidates and watched applicants’ interviews, was that the mission is surrounded by a certain rhetoric of progress. Going to Mars will move humanity forward and open up new frontiers; it will be a veritable leap for mankind. I watched a woman look forward to the day her statue will be planted on Mars’s red soil in honour of her services to mankind. I watched a father willing to leave his wife and children behind for a chance to make this jump for humanity. I watched a young man speak of his application as a “sacrifice” for the rest of us. Through the glories of modern science, mankind is once again forging ahead. Continue reading...

Hannah Earnshaw explains why she wants to be part of the mission to colonise the red planetI have always been in awe of the night sky, trying to comprehend the vastness of space and the countless wonders it contains. But I have always felt a certain dissatisfaction with only being able to see it at a distance.One day I imagine that humanity will be able to visit other planets in the solar system, and venture even further to other stars, but this has always seemed very far away. That’s the reason why I applied for the Mars One mission, aimed at starting a human colony on Mars – it seemed like a real opportunity to get closer to the rest of the night sky, to give me a chance to be a part of taking humanity into the stars.Related: Mars One shortlist: five Britons among 100 would-be astronauts Continue reading...

The spectacular fall of the Japanese scientist who claimed to have triggered stem cell abilities in regular body cells is not uncommon in the scientific community. The culprit: carelessness and hubris in the drive to make a historic discoveryThe year 2014 was one of extremes for Haruko Obokata. A year of high highs and even lower lows. Barely 30 years old, she was head of her own laboratory at the Riken Center for Developmental Biology (CDB) in Kobe, Japan, and was taking the male-dominated world of stem cell research by storm. She was hailed as a bright new star in the scientific firmament and a national hero. But her glory was short-lived and her fall from grace spectacular, completed in several humiliating stages.

He may be adored for his portrayal of Hawkeye the wisecracking doctor in MASH, but Alan Alda has a second passion: science. Which is why he has written a play, Radiance, about the hounding of Marie CurieAlan Alda works from an office in midtown Manhattan, around the corner from Grand Central station and in the shadow of the Chrysler Building. “It’s funny,” he says, looking up at the skyscraper while waiting for a cab. “I come here every day and I never saw it from this angle before.”The veteran actor, now 79, is used to approaching things from unusual angles – it is what he has been doing, forcefully, for most of his career: taking the lessons learned from one area of expertise and applying them to another. So it is that, having just finished appearing nightly on Broadway, opposite Candice Bergen in Love Letters, Alda now has a production up and running at a much smaller venue: the Tabard in west London.

A new study by scientists at the University of Cambridge claims teenage sperm is genetically weak, but is the claim credible?Teenage boys already have plenty to worry about: spots, girls and the size of their “thing”, as Adrian Mole might have put it. Does the problem of having genetically weak adolescent sperm really need to be added to this list?Scientists at the University of Cambridge have suggested this is the case after carrying out a study involving more than 24,000 parents and their children. The analysis focused on tiny genetic differences between parents and offspring, which are assumed to be caused by copying errors in the egg or sperm cells. Continue reading...

Penguins have bad taste, at least compared to other birds. Based on their genes, it’s unlikely they can sense sweet, umami or bitterA penguin’s sense of taste appears to be limited to just sour and salt. Genetic research suggests that of the five vertebrate senses (sweet, umami, bitter, sour and salt), penguins only have taste receptors for sour and salt.If you were to make a microscopic inspection of a penguin’s tongue, you’d find something fishy. “The lack of taste buds strongly suggests a reduction in taste function,” write the authors of a paper just out in Current Biology. This supposition is supported by their observation that Adelie and Emperor penguins (and by extension all other penguins) only have taste receptors responsive to sour and salt. Continue reading...
