Three recent important research developments, all readable in one minute
The narwhal's tusk possesses a distinctive double twist, featuring left-handed and right-handed layers of microscopic collagen fibrils. These opposing twists generate internal tension, enabling the tusk to maintain a straight and robust structure. This unique formation may provide insights into how tissues incorporate patterns to develop specific mechanical characteristics.
Recent research has revealed that psychedelics do not disorganize brain signals as previously thought. Instead, a study of 62 adults found that psilocybin usage led to brain activity aligning more closely with the individual's environment, a phenomenon termed "embeddedness." This enhanced alignment was associated with improved mood, indicating that the connection to surroundings may play a crucial role in the therapeutic effects of psychedelics.
When subjected to shock waves of 1 terapascal, equivalent to roughly 10 million times Earth's atmospheric pressure, diamond samples remained intact and did not undergo structural changes. Instead, their melting point only slighty decreased. These findings could aid in understanding the conditions within giant planets such as Neptune and in optimizing nuclear fusion processes that employ diamond components.
