Researchers have identified how cells in our brains work together to join up memories of separate experiences, allowing us to make educated guesses in everyday life. By studying both human and mouse brain activity, they report that this process happens in a region of the brain called the hippocampus. Source: Scientists discover what happens in […]

The scientists found that the more curved a toe spring is, the less power the foot inside the shoe has to exert when pushing off from the ground while walking. That means foot muscles are doing less work, and this, the researchers hypothesize, may have consequences such as less endurance and make people more susceptible […]

Scientists have found that the ‘segmentation clock’ — a genetic network that governs the body pattern formation of embryos — progresses more slowly in humans than in mice because the biochemical reactions are slower in human cells. The differences in the speeds of biochemical reactions may underlie differences between species in the tempo of development. […]

Researchers have developed a new method to determine – rapidly, easily and cheaply – how effective two antibiotics combined can be in stopping bacterial growth. The new method is simple for laboratories to use and can provide greater scope for customizing treatment of bacterial infections. Source: New high-speed test shows how antibiotics combine to kill […]

Students who are quizzed over class material at least once a week tend to perform better on midterm and final exams compared to students who did not take quizzes, according to a new meta-analysis. The researchers found in addition to frequency, immediate feedback from instructors also seemed to positively impact student performance. Source: Quizzes improve […]

Limitations in DNA sequencing technology make it difficult to detect some major mutations often linked to cancer, such as the loss or duplication of parts of chromosomes. Now, methods developed by computer scientists will allow researchers to more accurately identify these mutations in cancerous tissue, yielding a clearer picture of the evolution and spread of […]
