Research by Brazilian scientists at D'Or Institute for Research and Education reveals Zika virus infection in human neural stem cells causes cell death, malformations, and reduced growth in neurospheres and brain organoids. The study highlights the etiological nature of microcephaly cases in Brazil.
A small study suggests Zika virus may be associated with an autoimmune disorder attacking the brain's myelin, similar to multiple sclerosis. Researchers found six people developed neurologic symptoms consistent with autoimmune disorders and underwent exams and blood tests, revealing signs of damage to the brain's white matter.
Researchers suggest that Neanderthals across Europe were infected with diseases carried out of Africa by waves of anatomically modern humans. This could have weakened the hunter-gathering Neanderthals and contributed to their extinction.
A large study found that fatty liver disease is common among liver transplant recipients, with a significant increase in prevalence over time. The condition is linked to various risk factors, including high body mass index, elevated blood triglycerides, and type 2 diabetes, but does not affect short-term patient survival.
Researchers found that exposure to cigarette smoke and flu viruses reduces the effectiveness of common COPD medication salbutamol. A new model could help identify alternative treatments for patients with these symptoms.
Geologists now track tectonic plate motion to understand ocean and mountain range formation, as well as animal species distribution. The technology reveals new geological relationships in Papua New Guinea and the Solomon Islands, with implications for predicting earthquakes and volcanic eruptions.
Researchers found that applying a magnetic field to PdCoO2, a non-magnetic metal, increases its electrical conductivity and reduces resistance. The phenomenon was linked to the material's layered crystal structure and topological characteristics.
A new lipid, LPA, has been found to regulate lymphocyte motility in narrow lymph nodes. LPA enables efficient movement through spaces jammed with immune cells and stromal cells. This discovery may lead to novel strategies for controlling immune responses.
A new Boston College study found that four leading teacher education rating systems lack evidence-based policies, questioning their validity. The researchers concluded that these accountability policies assume teachers are the primary solution to educational inequality, ignoring systemic societal inequalities.
