Science is deeply imaginative. Why is this treated as a secret?

Science is deeply imaginative. Why is this treated as a secret?

By Tom McLeish My latest book, The Poetry and Music of Science (2019), starts with my experiences of visiting schools and working with sixth-form pupils in general-studies classes. These students, aged 17-18, would tell me that they just didn’t see in science any room for their own imagination or creativity. Not just on one occasion but repeatedly I heard this from young people bright enough to have succeeded at any subject to which they set their minds.  Yet it doesn’t…

DEA seeks major increase in federally-approved cannabis production to meet growth in research needs

DEA seeks major increase in federally-approved cannabis production to meet growth in research needs

The Motley Fool reports: The U.S. Drug Enforcement Agency (DEA) had an opportunity to reschedule or de-schedule marijuana back in the summer of 2016 in response to two petitions but chose not to take any action. However, news out of the DEA this past week might signal that the regulatory agency is changing its tune, or at least softening its stance, on marijuana. As reported by Forbes, the DEA has requested an annual grow quota of 3,200,000 grams (about 7,055…

How rich donors like Epstein (and others) undermine science

How rich donors like Epstein (and others) undermine science

Adam Rogers writes: Imagine a billionaire with an abiding interest in science, but also in having sex with young girls. He’s famous, our billionaire, and he associates with what used to be called boldface names, some of whom know—they’d have to, right?—about his habits. But they let it go. And eventually the billionaire’s name gets associated with all sorts of do-gooderish public endeavors, before the truth gets told—mostly after the billionaire’s death under salacious and suspicious circumstances. To be clear—not…

Can physicists rewrite the origin story of the universe?

Can physicists rewrite the origin story of the universe?

Jess Romeo writes: During a 2015 conference on theoretical cosmology at Princeton University, Roger Penrose, a pioneer in the field of mathematical physics, was asked to speak on a panel about the origin of the universe. For decades, the leading theory had been that, during roughly the first trillionth of a trillionth of a nanosecond following the Big Bang, there was a single period of extremely rapid expansion, known as inflation, that formed the universe we observe today. When it…

NOAA’s chief scientist stands up for scientific integrity and against political interference

A Message from Craig McLean: Hurricane Dorian and Exceptional Service, addressing his colleagues, states: During the course of the storm, as I am sure you are aware, there were routine and exceptional expert forecasts, the best possible, issued by the NWS Forecasters. These are remarkable colleagues of ours, who receive our products, use them well, and provide the benefit of their own experience in announcing accurate forecasts accompanied by the distinction of all credible scientists—they sign their work. As I’m…

We scientists must rise up to prevent the climate crisis. Words aren’t enough

We scientists must rise up to prevent the climate crisis. Words aren’t enough

Charlie Gardner and Claire Wordley write: As scientists, we tend to operate under an unspoken assumption – that our job is to provide the world with factual information, and if we do so our leaders will use it to make wise decisions. But what if that assumption is wrong? For decades, conservation scientists like us have been telling the world that species and ecosystems are disappearing, and that their loss will have devastating impacts on humanity. Meanwhile, climate scientists have…

Climate change advancing faster than scientists previously thought

Climate change advancing faster than scientists previously thought

Naomi Oreskes, Michael Oppenheimer, and Dale Jamieson write: Recently, the U.K. Met Office announced a revision to the Hadley Center historical analysis of sea surface temperatures (SST), suggesting that the oceans have warmed about 0.1 degree Celsius more than previously thought. The need for revision arises from the long-recognized problem that in the past sea surface temperatures were measured using a variety of error-prone methods such as using open buckets, lamb’s wool–wrapped thermometers, and canvas bags. It was not until…

In a review of Violet Moller’s new book, The Map of Knowledge: A Thousand-Year History of How Classical Ideas Were Lost and Found, Katie Hafner writes: While religion dictated the cultural winds of the Western world, ideas flowed freely through the Middle East, traversing religions and cultures. Knowledge began flowing into Baghdad from every direction as scholars translated Greek manuscripts into Arabic. Book production soared as texts were read aloud to roomfuls of scribes so that many copies could be…

NASA should focus on saving Earth

Lori Garver, former deputy NASA administrator, writes: In a July Pew Research Center study, 63 percent of respondents said monitoring key parts of Earth’s climate system should be the highest priority for the United States’ space agency — sending astronauts to the moon was their lowest priority, at 13 percent ; 18 percent favor Mars. The public is right about this. Climate change — not Russia, much less China — is today’s existential threat. Data from NASA satellites show that future generations here…
