Reagent pencils, turning chemistry into child’s play

Tweet Follow @Sci_ents If you’ve ever sat opposite a doctor and wondered what she was scribbling on her notepad, the answer may soon not only be medical notes on your condition, but real-time chemical preparations for an instant diagnostic test. Thanks to the work of a team of researchers from California Polytechnic State University, recently … Continue reading »

A review of Philip Schewe's "Maverick Genius", a biography of Freeman Dyson

Freeman Dyson is a unique treasure; he is not only a brilliant and accomplished physicist who has made important contributions to an astonishingly diverse range of topics in physics and mathematics, but he is also one of the very few scientists around who can craft genuinely eloquent prose.

The Food Babe quiz. Can you tell Vani Hari quotes from other irrational nonsense?

Tweet Follow @Sci_ents By now I’m sure you’ve all seen the ravings of Vani Hari a.k.a. Food Babe. Her one women campaign to spread fear through nonsense has netted her (in)fame, fortune and influence. Not to mention a pretty strong back lash from the rational side of the internet. So to test if you’ve been paying … Continue reading »

More than two thirds of California is in “extreme” or “exceptional” drought this year, according to the University of Nebraska’s drought monitor website. The irony that California borders the Pacific Ocean, which contains 187 quintillion gallons of undrinkable water, is not lost on scientists and legislators. Show More Summary

The Hubble Space Telescope was launched 25 years ago today. Rumor has it that whale oil was used to lubricate its internal moving parts. Was whale oil ever actually sent into space? Read this article from our magazine to find out. Image: (Flickr user aaroneoustruths)

What is the probability of a chemist discovering a drug? Is that the right question?

Over on Twitter there has been a lively discussion sparked by a question from C&EN's Lisa Jarvis: What is the probability that a medicinal chemist will discover a marketed drug in his or her career? I have some interest in this question...Show More Summary

Blogroll: Comment etiquette

Moore's Law turns 50: The End of the Beginning?

The cost of gene sequencing has surpassed even Moore's Law. Nature has a perspective reminding us that Moore's Law turns fifty this month. The article talks about the ramifications of the law for the physics of transistors and electronics. Show More Summary

One hundred years ago today, a small unit of German soldiers lugged more than 5,000 90-pound steel cylinders into the small Belgium town of Ypres. After unscrewing the caps, they turned and ran as fast as they could upwind. As the contents...Show More Summary

Shape vs vibration: Continuous rather than discrete?

There's an article in C&EN by Sarah Everts on a new paper by Eric Block's group at SUNY Albany that throws a rather large stone at the window constructed by Luca Turin's vibrational theory of smell. As readers interested in the topic...Show More Summary

The Romance of Chemistry

We’ve spent the past week looking at Moore’s law, its history, implications, and what it might look like in the future. But today, on the 50th anniversary of the publication of his landmark paper, we want to consider the making of Moore the man. Show More Summary

It’s time science reclaimed health food from the quacks

Tweet Follow @Sci_ents I’m not quite sure what came over me, I’d set out in search of a beer and a burger. But somehow ended up in a juice bar wolfing down falafel, quaffing a cucumber, celery, ginger smoothie and sprinkling sweet potato chips with some strange pink salt. And it was good. Really, really … Continue reading »

Do these dolls look familiar? In 1997 Intel released the Pentium II processor and advertised it with commercials starring “BunnyPeople.” That name is not a reference to the animals with floppy ears; bunny suits are protective clothing worn by lab technicians who build microprocessors.

Check out our trailer of CHF’s new video about Gordon Moore and his influence on the world. Go to after 4:30 p.m. EDT to watch the full film. Tomorrow we revisit an Intel advertising gem from the 1990s.

Nobelist John Pople on using theories and models the right way

John Pople was a towering figure in theoretical and computational chemistry. He contributed to several aspects of the field, meticulously consolidated those aspects into rigorous computer algorithms for the masses and received a Nobel for his efforts. Show More Summary

Three Reasons Why Moore’s Law Might Be Doomed

On April 19, 1965, Gordon Moore published a prediction that would shape the computer industry for the next 50 years: every year the number of transistors that fit on a microchip will double. (A transistor is basically an electric switch that allows a computer chip to make calculations.) In 1975 he revised this rate to every two years. Show More Summary

Moore and the Microprocessor

Gordon Moore first published the article containing what would become his namesake law 50 years ago this week. At the time he was serving as research director at Fairchild Semiconductor. Fairchild had pioneered the development of the...Show More Summary

A letter from a chemist to homeopaths

Tweet Dear Homeopaths, Homeopathy awareness week is here again. And I’ve got some questions about this most popular of alternative therapies. The answers to which I’d very much like to be aware of. Homeopath, as I understand it (please correct me if I’m wrong), is based on a idea that ‘like cures like’. So if your … Continue reading »

A graph from Gordon Moore’s “The Future of Integrated Electronics” from 1965: an article that lays out Moore’s belief that the number of transistors on a microchip would double every year. Click here to read the entire paper. Come back Wednesday to see a circuit board from CHF’s collections and learn about how Intel built the first computer chip.
