Lots of people think they're allergic to penicillin, but aren't -- so when they have infections, doctors are obliged to skip the front-line drugs, which accelerates the pace of antibiotic resistance in common bacteria. Read the rest
University of Western Ontario researchers examined the electrical activity in several patients before and after their life support was turned off and they were declared clinically dead, when the heart had stopped beating. In one patient, brain waves, in the form of single delta wave bursts, continued for minutes after death.
"It is difficult to posit a physiological basis for this EEG activity given that it occurs after a prolonged loss of circulation," the researchers write in their scientific paper. "These waveform bursts could, therefore, be artefactual in nature, although an artefactual source could not be identified."
This kind of research in the niche field of necroneuroscience is relevant to ethical discussions around organ donation and how the moment of death is defined.
Water is viscous. With heat, the viscosity drops. And you can hear the difference in its splash.
Last year, MIT News editor Maya Weinstock submitted her Women of NASA minifigures design to LEGO Ideas. LEGO has just approved the idea and laster this year or early 2018 will release an official minifig set of these five inspiring women in science:

Margaret Hamilton, computer scientist: While working at MIT under contract with NASA in the 1960s, Hamilton developed the on-board flight software for the Apollo missions to the moon. She is known for popularizing the modern concept of software.
Katherine Johnson, mathematician and space scientist: A longtime NASA researcher, Johnson is best known for calculating and verifying trajectories for the Mercury and Apollo programs — including the Apollo 11 mission that first landed humans on the moon.
Sally Ride, astronaut, physicist, and educator: A physicist by training, Ride became the first American woman in space in 1983. After retiring as a NASA astronaut, she founded an educational company focusing on encouraging children — especially girls — to pursue the sciences.
Nancy Grace Roman, astronomer: One of the first female executives at NASA, Roman is known to many as the "Mother of Hubble" for her role in planning the Hubble Space Telescope. She also developed NASA's astronomy research program.
Mae Jemison, astronaut, physician, and entrepreneur: Trained as a medical doctor, Jemison became the first African-American woman in space in 1992. After retiring from NASA, Jemison established a company that develops new technologies and encourages students in the sciences.
Psychologist Gert Storms doesn't want to review scientific papers if their authors refuse to share with him the underlying data. The American Psychological Association (APA), which publishes the journal he edits, has asked him to resign.
Nature.com's Gautam Naik reports that the effort to force him out is a test of The Peer Reviewer's Opennness Initiative, a move crafted to "increase transparency in a field beset by reports of fraud and dubious research."

Storms, a psychologist at the Catholic University of Leuven in Belgium and a consulting editor for the APA’s Journal of Experimental Psychology: Learning, Memory, and Cognition, accepted an invitation last year to review a study for the journal, and pointed out his new open-data policy. The journal's editor, Robert Greene, wrote back to say that Storms’s stance set “a terrible precedent” because it was unfair to the author of the paper and opposed the APA’s policies and the guidelines followed by other reviewers. “Given that your policy conflicts with that of the journal, I think that it's best that you step down from the editorial board,” he wrote.
Storms refused, writing that he would continue to do what he thought was necessary to “prevent sloppy science”. And he forwarded his correspondence to other editors at the journal. Two of them, Robert Hartsuiker and Marc Brysbaert, both psychologists at Ghent University in Belgium, wrote to Greene saying that they, too, would quit if Storms was forced to resign. "The policy of asking people to leave rather than inviting a discussion and getting critical voices — I found that quite inappropriate," said Hartsuiker.
In 1958 in an Illinois creek bed, an amateur fossil collector named Francis Tully discovered the fossilized remains of a bizarre creature that resembled a mollusk, insect, and worm yet was none of those things. Since then, thousands of 300 million-year-old fossilized "Tully Monsters" have turned up and the creature was officially named as the Illinois state fossil.
KSU plant biochemical geneticist Raj Nagarajan describes the properties of Thaumatin, Monellin and Brazzein, all found in west African plants that are generally considered safe for consumption; each is a protein, and they are, respectively, 1,000x, 2000x, and 3000x sweeter than sugar. Read the rest
The amazing suckers on octopus arms aren't just for sucking. They also are used to smell and taste. To deal with all that sensory input, the vast majority of an octopus's brain cells are in its eight arms!
“It’s more efficient to put the nervous cells in the arm,” neurobiologist Binyamin Hochner, of the Hebrew University of Jerusalem, told KQED's Deep Look. “The arm is a brain of its own.”
Magdalena Cerdá and Garen Wintemute are epidemiological researchers with US Davis's Violence Prevention Research Program; when they witnessed the Trump administration's mass-deletion of publicly funded EPA research, they feared gun violence stats would be next. Read the rest
A trio of "scientists against a fascist government" set out a program for resisting trumpism with science, delving into the moral duty of scientists to resist the perversion of their work to attain cruel and evil ends. Read the rest
