9:05 AM | Predictive text: Darwin’s computers
Charles Darwin’s IBM computers There are lots of quotes around attributed to the great and the good throughout the years, but often these are anything but direct quotes and in some cases turn out to have far more intriguing origins. For example, the quote often attributed to Thomas John Watson, Sr. (1874–1956) who was chairman […]Predictive text: Darwin’s computers is a post from the science blog of science journalist, photographer and musician David […]

12:16 AM | "N": "a very blunt conversation with my boss"
From "N", their story of why they quit graduate school in chemistry:After three and a half years of graduate school, I left the program with a Master of Science degree. I was attending graduate school that had a smaller faculty, lots of equipment, and is located in a beautiful area. To fully understand my dilemma, I wanted to study synthetic chemistry, but I didn't feel comfortable with the available research groups once I was already enrolled at the University. I joined an [redacted by CJ: […]

9:22 PM | Major Classes of Antidepressants
You might have noted that yesterday was ‘Blue Monday’ – lauded as the most depressing day of the year. You might also be aware that Blue Monday was actually the construct of a Sky Travel marketing campaign several years ago, and is complete pseudoscience. Still, it seemed like as good an excuse as any to throw together […]

9:12 PM | Vin Mariani: alcohol y coca para Su Santidad
Por suerte, esta bebida se prohibió en 1914¿Qué pasaría si os dijera que hubo una vez un papa que le pegaba al alcohol y la coca? Pensaríais que estoy loco o que manejo información privilegiada de los archivos del Vaticano. Pero no es así. La anécdota es real, tiene una explicación histórica y es bastante conocida en el mundillo de la toxicología, pero no por ello deja de ser sorprendente e interesante. Y creo que es […]

7:32 PM | Stories wanted: "I Quit Graduate School in Chemistry"
At the end of Vinylogous' recent excellent post on mental health and graduate school in chemistry, he posited questions that people considering leaving graduate school should consider: There's a pervasive thought--"I've already put in 2 years, so it would be a waste of time to quit now." (Or however many years). But time already invested is a sunk cost. It doesn't matter how much time you've put in if you're not going to get anything out of the degree. Only three factors should matter when […]

3:57 PM | Glassdoor Review of the Week: Moderna Therapeutics
Speaking of Moderna, I am reminded that a couple weeks ago, someone at In the Pipeline posted a pretty awesome-not-awesome Glassdoor review of them (the review was written a year ago): Moderna takes advantage of all employees below the executive level- overworked and grossly underpaid, they feel as though they can get away with this type of behavior because of rival companies recently closing their doors. When the bubble bursts, the executives will have handsome rewards while the little […]

1:06 PM | Wearable nanowire sensor clears path to long-term EKG, EMG monitoring
Researchers have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography (EKG) or electromyography (EMG). The new sensor is as accurate as the 'wet electrode' sensors used in hospitals, but can be used for long-term monitoring and is more accurate than existing sensors when a patient is moving.

10:53 AM | Atoms can be in two places at the same time
According to the predictions of quantum mechanics, microscopic objects can take different paths at the same time. The world of macroscopic objects follows other rules: objects always moves in a definite direction. But is this always correct? Physicists have constructed an experiment designed to possibly falsify this thesis. Their first experiment shows that Caesium atoms can indeed take two paths at the same time.
