Stem cell ‘organoid’ mimics developing brain

0
Scientists are using stem cell-derived tissue models to reduce the number of drug failures in clinical trials. The findings offer a cost-effective approach for assessing chemical safety. The researchers have developed a screening system for predicting...

Some ants are lucky: Their job is being lazy

0
Humans aren’t the only species that can be notoriously lazy. A new study with ants shows some spend the majority of their time in a consistent state of rest. The findings even suggest inactivity may...

Is ecology too quick to say species are cheating?

0
Is cheating really widespread among “mutualists”—species that cooperate for mutual benefit? It’s a commonly held belief in ecology, but a new look at dozens of key studies finds very little evidence to back it...

How suicide in sci fi helps us deal with change

0
A new book argues that science fiction’s fascination with characters in suicidal crisis has been a part of the genre from the beginning. A few examples: A husband persuades his wife to commit a “pretend” suicide, only...

Does BPA make mice daughters lazy?

0
When female mice are exposed to bisphenol A (BPA), a chemical found in plastics, or to ethinyl estradiol (EE), the estrogen in birth control pills, their daughters exercise less and have slower metabolisms. Both BPA and EE...

Zoom in on metallic glasses to find fractals

0
Metallic glasses are very strong and elastic materials that appear with the naked eye to be identical to stainless steel. But metallic glasses differ from ordinary metals in that they are amorphous, lacking an...

A kid’s math ‘self-concept’ predicts test scores

0
How strongly children identify with math—their math “self-concept”—can predict how high they will score on a standardized test of math achievement, a new study shows. The study also measured the strength of students’ stereotype that “math...

A new book uses insights into the reading brain to give writers clear-cut, science-based guidelines on how to write anything well, from an email to a multi-million-dollar proposal. Yellowlees Douglas, an associate professor of management communication...

Scientists release first draft of the ‘supertree’ of life

0
Scientists have just released a first draft of the “tree of life” for the roughly 2.3 million named species of animals, plants, fungi, and microbes. The tree depicts the relationships among living things as they...

Scientists zoom in on 2 brain cells touching

0
A new technique is letting scientists study the exact way two brain cells interact. The work focuses on myelin, the fatty insulator that enables communication between nerve cells. Cellular interactions that trigger the production of...
