Uncovering the clock that sets the speed of embryo development

Why do pregnancies last longer in some species than others? Researchers have found the clock that sets the speed of embryonic development and discovered the mechanism is based on how proteins are made and dismantled. The study could also help us understand how different mammals evolved from one another and help refine methods for regenerative […]

A scientific first: How psychedelics bind to key brain cell receptor

For the first time, scientists solved the high-resolution structure of these compounds when they are actively bound to the 5-HT2A serotonin receptor on the surface of brain cells. This discovery is already leading to the exploration of more precise compounds that could eliminate hallucinations but still have strong therapeutic effects. Psilocybin – the psychedelic compound […]

Scientists discover what happens in our brains when we make educated guesses

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 […]

Curve at tip of shoes eases movement but may lead to weaker muscles, problems

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 […]

Humans develop more slowly than mice because our chemistry is different

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. […]

New high-speed test shows how antibiotics combine to kill bacteria

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.

Quizzes improve academic performance

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 […]

Algorithms uncover cancers' hidden genetic losses and gains

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 […]
