Scientists created a mixture of silicone-coated and normal sand to study the behavior of wet granular materials. Adding a certain threshold of magic sand leads to an abrupt change in clustering and rigidity, allowing for the tuning of flow properties.
Researchers at Göttingen University have discovered that adult mice brains display increased experience-dependent spine removal, a hallmark of critical period-like plasticity. This study reveals structural changes in the visual cortex associated with silent synapses and sheds light on lifelong neural plasticity.
The DESIRE study found that efficacy was the strongest determinant of participants' stated modality choice, followed by delivery method and side effects. Participants preferred a douche used 30 minutes before sex with 95% efficacy, offering three to five days of protection.
