Phys.org / Unique instruments automate sample preparation, quality control for cryo-electron microscopy
Cryo-electron microscopy (cryo-EM) can help scientists determine the three-dimensional structure of proteins in unprecedented detail. Jacques Dubochet, former group leader at EMBL, shared the 2017 Nobel Prize in chemistry ...
Medical Xpress / Fat tissue could explain triple negative breast cancer spread—and point to treatments
Triple-negative breast cancer (TNBC) is aggressive and hard to treat. But the role of fat tissue in how the cancer spreads may help point toward new understanding and treatments, according to a new paper from scientists at ...
Phys.org / Symbiotic partner-swapping or long-term fidelity? Partnership success between beetles and bacteria revealed
Some insects and microbes develop symbiotic partnerships that become so interdependent they can no longer survive without each other. But how specific are these heritable symbioses? Is it possible for the same species of ...
Medical Xpress / Steep drop in metabolic coenzyme could trigger preterm labor
Declining placental concentrations of a molecule that plays a key role in metabolism appear to trigger the end of pregnancy and hasten labor and delivery, suggesting a study co-led by researchers at UT Southwestern Medical ...
Tech Xplore / Meta offers lower cost glasses as wearables competition heats up
