Researchers have developed a protein-based coating that can help rehabilitate long-term brain function and prevent the brain's immune response from rejecting brain-computer interface electrodes. The coating, using an interleukin-1 receptor antagonist, has shown promising results in pre-clinical studies with animal models.
A new approach to treating triple negative breast cancer and clear cell renal cell carcinoma has been discovered by researchers at Mayo Clinic. The approach involves activating a potent tumor suppressor gene called sFRP1, which is silenced in these cancers. Once activated, the laboratory tumor cells stopped growing and died.
Scientists at University of Leeds used Diamond Light Source to study calcium oxide-based materials as CO2 sorbents. They found a mechanism for interaction between CaO and water, which led to disintegration and generation of nano-sized crystallites. This new knowledge aims to improve the efficiency of this economically viable method.
A Mayo Clinic-led analysis found that approximately 1.8 million Americans suffer from undiagnosed celiac disease, while 1.6 million use a gluten-free diet without medical confirmation.

A study by the University of Western Australia has identified 8% of Olympic athletes with asthma and airway hyper-responsiveness, with summer sports showing a higher prevalence. Intense training may be a contributing factor, while genetic aspects also play a role in airway damage.
Research on prospective memory reveals that failures occur when we form intentions but lose focus due to interruptions or multitasking. Habital tasks can also lead to implicit intentions, making it harder to remember them. To defend against these failures, professionals use memory tools like checklists and implementation intentions.
A new report concludes that commercial 'wildlife encounter' operations promoting captive lion reintroduction do little to conserve African lions. Wild-born lions are better equipped for survival and release compared to captive-bred ones. These programs divert critical resources from projects addressing declining wild lion populations.
Researchers found anxiety is a stronger risk factor for prolonged and frequent sick leave than depression alone. The study, which followed 13,436 participants over six years, also showed that pain can impact the association between common mental disorders and sick leave.
Research published in the FASEB Journal reveals a link between maternal stress and abdominal obesity in mice offspring. The study found that manipulating the neuropeptide Y system in visceral fat may prevent stress-induced obesity, offering potential insight into how to counteract the negative effects of stress.
