Researchers studying p53, the heralded cancer-fighting ‘guardian of the genome,’ found that the human protein also plays a role in promoting tumors, in addition to suppressing them. They found that the PUMA protein works inside the cell’s mitochondria to switch energy production processes and stimulate cancer growth. Source: Opposite effect: Protein widely known to fight […]

Researchers revealed that the immune cells basophils caused emphysema in mice with COPD-like features induced by intranasal administration of elastase. They showed that basophils, previously linked mainly to allergies and fighting parasites, initiated a cascade of reactions eventually leading to the release of excess MMP-12 and the destruction of alveolar walls. The team hopes that […]

In a context of overuse of insecticides, which leads to the selection of resistant mosquitoes, it is already known that this resistance to insecticides affects interactions between mosquitoes and the pathogens they transmit. Researchers demonstrate that mechanisms of insecticide resistance, observed in Culex quinquefasciatus vector, impact the transmission of West Nile virus. Source: Insecticide resistance […]

Researchers showed that we can acquire the vocabulary of a new language during distinct phases of slow-wave sleep and that the sleep-learned vocabulary could be retrieved unconsciously following waking. Memory formation appeared to be mediated by the same brain structures that also mediate wake vocabulary learning. Source: Learning new vocabulary during deep sleep

In a single sneeze or a cough, as many as 40,000 tiny droplets are forcibly propelled from our mouth and nose into the air. While we cannot control our sneezing, researchers have recently developed an original method to collect micro-droplets, such as these ‘precious’ human dewdrops, which may shed light on applications in detecting disease-causing […]
